The present invention provides a folding portable display device having an effect of viewing at least one screen by interconnecting at least two flat panel displays. As a flat panel display panel, LCD, OLED, FED, PDP, Electric Paper, etc. can be used, but not limited to this, any flat panel display can be used.

And, when the panel housing in the stacked state up and down is unfolded, the two displays are connected to each other within 0.1mm or more and less than 5mm to form a single screen.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to an accompanying drawing and an Example.

Example 1

1 illustrates a portable display device of the present invention.

FIG. 1 is a view illustrating a state in which the

displays

2 and 4 are unfolded. The upper panel housing 20 includes an upper display 2, and the lower panel housing 40 includes a lower display 4. The upper and

lower panel housings

20 and 40 are provided in the housing 50.

As shown in the figure, a lower panel housing 40 on which the lower display 4 is mounted is provided below the upper panel housing 20 on which the upper display 2 is mounted. That is, the upper panel housing 20 and the lower panel housing 40 overlap each other and are formed by being stacked.

Then, the housing 50 for fixing the upper and

lower panel housing

20, 40 is provided. Therefore, it is possible to grasp the handle 45 and to slide the lower panel housing 40 in the horizontal (arrow) direction.

3 is a diagram illustrating a state in which the display is slid.

As shown in the figure, the lower panel housing 40 and the lower display 4 are unfolded so that the screen is expanded. In this case, the protective cover 43 is connected to the lower panel housing 4 and moves together.

Then, when the lower panel housing 40 is moved upward in the vertical direction (arrow), as shown in FIG. 1, the lower display 4 and the upper display 2 are adjacent to each other to form one screen. It becomes the structure that there is. At this time, the heights of the upper and

lower displays

2 and 4 are the same.

When the protective cover 43 is pressed, it enters into the lower panel housing 40 to be received. That is, when the upper display 20 and the lower display 40 are unfolded, the protective cover 43 can be stored as shown in FIG. 1.

4 is a view illustrating a panel housing with a protective cover removed.

As shown in the figure, the side of the

display

2, 4 is mounted close to the panel housing side wall 20a.

In general, the input device 250 is often provided at the top of the

display

2, 4, and accordingly, the embodiment of the present invention includes the input device 250 at the top of the

display

2, 4.

In addition, the

displays

2 and 4 are mounted to the panel housings 20 and 40 while being mounted to the chassis 16. Thus, the input device 250 is provided on the top of the chassis 16.

To this end, the attachment part 16c is provided on the side of the chassis 16 so that the input device is attached. It is obvious that the attachment portion 16c may use a double-sided adhesive, and an adhesive such as an adhesive bond may be used. In addition, fixing parts 16b are provided at both sides.

Meanwhile, the input device may not be provided separately from the display, but may be provided as a sensor in each pixel of the display, and in this case, the embodiment of the present invention may be applied. At this time, the sensor is a micro sensor element such as an optical sensor or a resistance sensor, various methods are possible.

display

2 and 4.

When there is a pixel 2n closest to the seam 8 as shown in the drawing, the distance J between the adjacent pixel 2n and the partition wall 2f is within 1 mm, and in the closest case, within 0.01 mm. Of course, the boundary of the pixel 2n and the boundary of the partition 2f may coincide with each other.

In addition, the thickness K of the partition 2f is also within 1 mm and at least 0.05 mm. Therefore, the distance between the pixel 2n closest to the seam and the edge boundary 2g of the

display

2, 4 is within 2 mm at least 0.06 mm or more.

In addition, the thickness of the chassis 16 shall not exceed 0.1 mm or more and 1 mm or less. However, the maximum thickness of the most efficient chassis 16 does not exceed 0.5 mm. Thus, the distance from the seam 8 to the boundary between the nearest pixel 2n and the chassis 16 is at most 2.5 mm and at least 0.16 mm.

Of course, it is not necessary that the boundary between the boundary line 2g and the partition wall 2f of the joint part 8 completely match, and the partition wall may be provided within the range of 0.001mm to 0.5mm at the boundary line 2g. . In this case, the distance from the closest pixel 2n to the outer boundary 16g of the chassis 16 in the seam 8 is at most 3.0 mm or 3.5 mm.

In general, an input device is mounted on an upper portion of a display to serve to input or select information. Accordingly, the portable display device of the present invention may further include an input device 250. However, the conventional input device should not be used as it is, but the input device 250 made by design change is used.

That is, in the input device, a lead wire reading a capacitance value or a resistance value is provided on each side of the input device. At this time, the position of the lead wire 250n in the joint portion must be changed. The partition 250f may also exist. Of course, the partition wall 250f may be omitted depending on the scheme.

The distance M between the lead wire 250n and the partition wall in the joint 8 is at least 0.005 mm to 1 mm, and the thickness L of the partition wall 250 f is also within 0.05 mm to 1 mm or 2 mm.

Therefore, in the seam 8, the distance between the lead wire 250n and the boundary 250g of the input device 250 is within 0.00mm to 2mm or within 3mm.

Of course, the boundary 250g of the seam 8 and the boundary of the partition 250f do not need to coincide completely, and it is natural that the partition 250f may be provided within a range of 0.5 mm from the boundary 250g. . In this case, the maximum value between the lead wire 250n and the boundary line 250g is 2.5 mm or 3.5 mm.

On the other hand, the partition wall does not necessarily need to exist depending on the input device method such as the capacitance method. In this manner, the distance between the boundary line 250g and the lead wire 250n is within 2mm or 3mm from 0.01mm (0.06mm minus the minimum thickness of the bulkhead 0.05mm).

250a represents an information input unit of the input device and may also be referred to as an active area in the input device. The structure varies depending on the resistive film type and the capacitive type, and although the conventional method is used, any type of input device may be used as long as the input device has a flat plate structure and inputs information through the surface of the input device. Of course it is included.

9 is a cross-sectional view of the display.

LCD can be used as the display, OLED or electronic paper, etc. can be used, and no matter which display is used, the distance between the display boundary 2g and the neighboring pixel 2n is very important in the seam 8, Naturally, the design values designed in the present invention can be applied to all flat panel displays as they are.

In the portable display device of the present invention, an OLED method is used, and a cross section of the structure is illustrated in FIG. 9.

The

display

2, 4 includes an insulating layer 53, an electrode 54, a coating electrode 58, an organic multilayer film 53, and the like on a substrate 51, and a moisture absorbing layer with a separator 57 interposed therebetween. 56 may also be further provided.

Then, the substrate 51 is covered with the cover substrate 52. In this case, the partition 2f may be a sealant formed of an adhesive or the like, but it is obvious that the substrate may serve as the partition 2f.

That is, when the substrate surface is partially removed by an etching process to make a space inside the substrate surface, and then an insulating layer and an organic multilayer or electrode are formed, the edge portion of the substrate remaining in the etching process serves as the partition wall 2f. It is natural to be able to.

As shown in the drawing, the neighboring pixels 2n should be formed closely in the joint portion 8, and the extent to which the neighboring pixels 2n are formed is the same as in the embodiment of FIG. 7.

On the other hand, although the chassis 16 partially covers the screen non-display area at the top of the

display

2, 4, the seam 8 should be determined at its value (" P " value in the figure).

That is, when a portion of the joint portion 8 covering the screen non-display area is referred to as "P", the distance of P is set to be within 2 mm or 3 mm as in the embodiment of FIG. Of course, the minimum value is 0.06mm or more. In this way, the display pixel 2n should not be covered. Naturally, at the seam, the chassis 16 should not cover the pixels of the

display

2, 4.

An input device 250 is provided so that the seam 8 of the

display

2 or 4 is mounted on the top of one side wall 20a of the panel housing.

In addition, a "" shaped cover 24 is provided at the top of the panel housing 20 to cover the edge of the non-display area of the

display

2 or 4.

As shown in the drawing, the display 2 and the input device 250 are separated from each other and mounted on the panel housing 20, and the cover 24 provided in FIG. 10 is not provided.

Accordingly, the input device 250 also serves as an external protective plate that protects the surface of the display 2 in the portable display device.

At this time, the ““ ”shaped mask printing 16d is applied to the input device 250. The mask printing 16d blocks the non-display area of the edges of the

display

2 and 4. The blocking effect is more visual.

Of course, as shown in the original, another embodiment of the mask printing 16d can also be seen, in which case the mask printing 16d is "" shaped but the seam is thinly formed, wherein the seam is thinly formed. The reason is the same as that in which the "P" value in Fig. 9 is determined.

The battery or circuit main body 29 is provided inside the panel housing 20, and the supporting part 26a is further provided. The support 26a supports the

display

2 and 4.

In addition, the panel housing side wall 20a of the joint portion 8 is formed with a step so that the

display

2 and 4 can be mounted on the step 20c. A protrusion 20d is formed to support the input device 250.

In general, when the input device 250 is provided on the top of the

display

2, 4, a predetermined gap exists between the display and the input device 250, and a protrusion 20d is formed to compensate for the gap. . Therefore, the thickness Y of the protrusion 20d is equal to the distance between the display and the input device. In addition, the length W from which the protrusion 20d protrudes should not exceed 2.5 mm or 3.5 mm in consideration of the non-display area of the display 2 and the thickness of the chassis 16. In addition, considering that the input device 250 is supported, the length W of the protrusion 20d should be at least 0.1 mm.

As shown in the figure, the upper cover 24 is omitted, and thus the input device 250 has a function of functioning as the upper cover.

In this case, each of the first supporting part 26a supporting the display 2 and the second supporting part 26b supporting the input device 250 are provided. However, the structure in which the display 2 and the input device are mounted on the joint 8 has a concept similar to that of FIG.

Therefore, the step 20c of the side wall 20a supports the display 2, and the protrusion 20d of the side wall 20a supports the input device 250. In this case, the length W of the protrusion 20d should not be beyond the screen non-display area of the display and should be 0.1 mm or more and 2.5 mm or less or 3.5 mm or less.

At this time, the protective film 20b is further provided to protect the side of the display 2 and the input device 250. In this case, the protective film 20b has a higher function of sealing effect than a function of protecting from physical shock. Therefore, the thickness does not need to be thick, but it is within 0.5mm from 0.01mm or more. Of course, when the protective film only to protect from external impact, the thickness of the protective film (20a) can be up to 1mm.

And, when the display (2) 4 is provided on the top of the side wall of the

panel housing

20, 40, a structure in which the protective film 20b is omitted can be made. At this time, the thickness of the chassis 16 can be thickened to serve as a protective film. And. In the figure, the "B" part of the boundary is coated with an adhesive, which can lead to a sealing effect (no protective film can be used to give the adhesive a sealing effect instead).

Meanwhile, in the case of FIG. 15, since the distance between the display 2 and the input device 250 becomes larger, the intermediate support part 30 is provided to support the input device 250.

In addition, the intermediate support part 30 is present in the non-display area of the display 2 joint part 8. Therefore, the intermediate support portion 30 has a width of at least 0.16mm to at most 2.5mm or 3.5mm, as described in FIG. 8.

FIG. 16 shows that the display 2 with the input device 250 is mounted to the panel housing 20, and FIGS. 17 and 18 show that the display 2 and the input device 250 are separate from the panel housing 20. It is divided into and it is a figure which shows that each is mounted.

In the panel housing 20, the third support part 26c is provided on the side wall 20a adjacent to the display so that the third support part 26c supports the display 2, and the display 2 is The input device 250 is supported.

However, when the input device 250 and the display 2 are separated and mounted on the panel housing 20 as in the case of 17, the fourth support part 26d is further provided on the side wall 20a of the panel housing 20. To support the input device 250.

Naturally, the width of the fourth support part 26d also has a value of at least 0.16 mm to at most 2.5 mm or 3.5 mm. That is, the fourth support part 26d is present in the screen non-display area at the joint part of the display 2.

In this case, since the screen non-display area is a non-display area in one display (mounted in the chassis), the screen non-display area when the two displays are adjacent to each other is within 5 mm or 6 mm.

When the display 2 is in close contact with the joint side wall of the panel housing 20 as shown in FIG. 16, if the reliability is considered, the thickness of the side wall of the panel housing 20 joint is 1.5 mm at maximum and the thickness of the chassis 16 is increased. It can be about 1mm. Therefore, the sum of the thickness of the chassis 16 that surrounds the display 2 seam side and the thickness of the side wall of the seam side of the panel housing 20 is 2.5 mm.

Therefore, when two

panel housings

20 and 40 are in close contact with each other, the distance between the two

displays

2 and 4 becomes 5 mm, which is twice the value of 2.5 mm.

On the other hand, as shown in Fig. 18, if the thickness of the

side walls

20a and 40a of the panel housing is 0.5 mm each (1 mm if the two side walls are combined), the thickness of the chassis 16 is also 0.5 mm, respectively. The distance between the

displays

2 and 4 does not become 5 mm. In this case, the distance between the displays is 2 mm.

However, as in the embodiment of FIG. 18, the

panel housing sidewalls

20a and 40a and the display 2 and 4 (the display mounted on the chassis) are located slightly apart so that the distance between the

displays

2 and 4 is 5 mm. Of course it can be. Similarly, even if the

panel housing sidewalls

20a and 40a are thinner and the chassis 16 is thinner, the distance between the displays can be 5 mm.

The distance between the input devices may also be determined based on the distance between the displays, that is, the distance between the display and the input device may be the same.

In addition, in the present invention, the chassis is a part that surrounds the display in the form of aluminum, but in some cases it may be in the form of plastic appliances. In addition, the chassis and the apparatus may be used together, and in all of these cases, the principle of covering the upper end of the joint part is in accordance with the present invention.

19 shows the support means between the display and the input device.

The

display

2 and 4 and the input device 250 are spaced apart at regular intervals, and the distance thereof may vary from 0.5 mm to 5 mm depending on the characteristics of the terminal. Therefore, it is necessary to separately support the input device, and this supporting means is shown in FIG.

Although the intermediate supporting part 30 and the fourth supporting part 26d have the same shape, the intermediate supporting part serves to support the input device 250 at the top of the display 2, and the fourth supporting part 26d is It is formed on the side wall 20a of the panel housing 20 to support the input device 250.

7 to 18 illustrate and illustrate one

display

2, 4, and

panel housing

20, 40 for convenience, the left and right symmetry around the seam 8, that is, the boundary portion. It goes without saying that another display and panel housing in place can be provided on the same principle.

19 is a view showing the shape of the intermediate supporting part 30, but it can be said that the shape of the fourth supporting part 26d is similar.

The width "W" of the center portion is 2.5 mm or 3.5 mm or less in the non-display area of the present invention.

20, 21 and 22 are views showing the supporting means in the form of another intermediate plate of the display and the input device.

The support means uses a transparent plastic plate. Transparent plastics include, for example, polycarbonate (PC) and polyethylene terephthalate (PET).

That is, the intermediate support plate may be made of a transparent plastic plate having a thickness of the distance from the display 2 (or the chassis 16) to the input device 250, or as shown in FIG. The plate 30a may be mounted to the display 2 and the chassis to serve as a supporting role.

In FIG. 20, "I" refers to one width of a wave pattern, and may have a size of about 0.2 to about 10 times the height "H". And, the height "H" is the height corresponding to the gap between the display (2) 4 and the input device 250.

In addition, the joint portion 8 may be provided with an intermediate plate 30b of the form of FIG. 21 made of a constant thickness and the other portion thinned. At this time, the height "H" corresponds to the distance between the display (2) 4 and the input device 250, the constant width "Z" refers to the width enough to effectively support the input device in the joint portion. Usually, the value of "Z" is determined within 0.2 to 20 times of "H".

In addition, as shown in Figure 22 may be provided with an intermediate plate (16c) supporting only the joint portion 8, the size of "H" and "Z" can be said to be the same as the case of 20, respectively.

23 shows a display with a connector attached.

Conventional displays and input devices are provided with a connector for connecting with the terminal body, in the present invention is to change the design of the connector.

As shown in the figure, the

display

2, 4 and the input device 250 is provided to have a symmetrical structure with respect to the joint portion (8). Here, a flexible printed circuit (FPC) 2c, 4c, 250c connecting the display device and the input device with the

connectors

2d and 250d is provided, wherein the

connectors

2d and 250d and the FPC are provided. (2c) (4c) 250c are mounted on opposite sides of the joint.

In this case, the connector 250d of the input device 250 may be connected to the

junction portions

2e and 4e of the

display

2 and 4 through a solder or the like. In this case, the connection between the input device 250 and the main body is also solved by the connection between the

connectors

2d and 4d of the

display

2 and 4 and the main body. In other words, the

display connectors

2d and 4d may include the function of the input device connector.

Then, the external signal line FPC is connected to one side of the display and the input device, and the external signal line is connected to one side of the opposite side of the joint shown in each of FIGS. 12 to 18.

Of course, when the

display

2, 4 and the input device 250 is separated and mounted on the

panel housing

20 and 40 separately (the embodiments of FIGS. 13, 15, and 17), the input device 250 When connecting the external signal line (FPC) to the, it is possible to select one side of the other three sides except the joint (8).

In FIG. 24, the part where the drive driver 2k (drive IC semiconductor chip) is located turns into a 4th side when a 1st side is a joint part. In other words, when the joint is made to the right side (in some cases, the left side), the portion where the drive driver 2k is located becomes the upper side or the lower side.

In order to mount the drive driver 2k on the fourth side, the supply line 2i connected to the panel electrode 2f on the first side or the third side is connected to the fourth side. That is, the supply line 2i is divided into one side and three sides to reach the fourth side. At this time, the supply line 2i is an electrical wire for connecting to the driving driver 2k to supply a signal line. In the present invention, the electrode 2f is simply expressed, but may actually mean a pixel electrode that transmits a driving signal to a TFT (Thin Film Transister).

Therefore, in this case, a margin of 1.5 mm is further added to the value of 2 mm, which is the sum of the value of "J" and "k" shown in FIG. That is, to secure a distance for the supply line 2i to pass within the 1,5mm. Therefore, the distance from the pixel closest to the display seam 8 to the boundary of the

display

2 and 4 is preferably no more than 3.5 mm.

25 is a view of another embodiment in which the connection supply line is changed;

When the first side is called a joint, the supply line 2i does not pass in the first side in order to minimize the joint. Then, all the supply lines 2i pass through the third side opposite to the seam 8, and the supply lines 2i meet the driving driver 2k. In this case, in the first side, the distance from the pixel closest to the joint portion 8 to the boundary line of the

display

2 and 4 can be 2.0 mm at the maximum.

Of course, depending on the design conditions, it is possible to make the supply line 2i pass a lot on three sides and to pass a little on the first side. That is, the rate at which the supply line 2i passes can be distributed to the third side and the first side at a constant ratio, respectively.

FIG. 26 is a diagram in which two displays are arranged. FIG.

The drawing illustrates an in-cell method in which the

input devices

200 and 400 are mounted directly on the upper side of the

display

2 and 4, and the driving driver is provided when the joint 8 is right (or in some cases left). FPC (2c) (4c) or the external connection connector (2d) (4d) to be connected to the lower side (may be the upper side in some cases).

Similarly, the FPC 250c and the connector 250d for connecting the input device are also positioned below.

Of course, if the display (2) 4 and the

input device

200, 400 is mounted at a predetermined interval apart, the input device connector can be mounted on three sides except for the joint portion.

27 to 30 are block diagrams illustrating the present invention.

In the present invention, two

displays

2 and 4 are provided, and two input devices 250-1 and 250-2 are also provided, and an input device is provided on the top of the display.

Therefore, the present invention is provided with a control unit for controlling the two display (2) (4), and also controls the signals output through the two input devices (250-1) (250-2).

As shown in FIG. 27, the controller 110, a memory 120, a time controller 125, a display driver 130, an input device driver 140, and the like are provided in the main body controller 105. .

That is, each element that functions as the controller 110, the memory 120, the time controller 125, the display driver 130, and the input device driver 140 may be provided in the main body controller 105. It can be manufactured and provided as a part of.

The display driver 130 divides the screen and sends data to the first display 2 and the second display 4, respectively. In addition, the input device driver 140 also corrects and adjusts signals output from the first input device 250-1 and the second input device 250-2, respectively.

In addition, in order to display the screen of the display (2) (4), the source (2b) (4b) section for providing a data signal and the gate section (2c) (4c) for providing a line selection signal Will be present.

In addition, the sensor 135 is a sensor that promotes the coupling state of the

panel housing

2 and 40. In other words. It is detected whether the upper and

lower panel housings

20 and 40 are coupled in a stacked state.

28 and 29 illustrate the display driver 130, and the driver 130 includes a column data processor 131 and a row data processor 132.

At this time, a method of dividing a display screen into two may be divided into source data and a gate signal.

As shown in FIG. 28, the column data processing unit 131 for supplying source data (data signal on the screen) supplies the same data signal to the first display 2 and the second display 4, and the raw data processing unit (Gate signal). In 132, the signal is divided and supplied to the first display 2 and the second display 4.

In this case, the degree of division is usually 1: 1 (120 lines each for the first second display if the entire screen is 240 lines), but the ratio may be adjusted according to the terminal design. For example, various ratios can be adjusted to the 140 lines of the first display and the 100 lines of the second display.

In the block diagram of FIG. 29, the raw data processing unit (Gate signal) 132 supplies the same data signal to the first display 2 and the second display 4, and supplies the source data (data signal on the screen). The supplied column data processing unit 131 divides and sends a signal to the first display 2 and the second display 4, respectively.

30 is a detailed view of the input device driver 140.

First, the calibration function performing unit 141 performs a calibration function on the input device 250 when the system is initially operated. According to a calibration function performed by the calibration function performing unit 141, a signal of a panel (a portion where information is directly input from the input device) corresponding to the correct coordinate value of the input device 250 is selected.

That is, the input device 250 signal corresponding to the coordinate value is selected according to the resolution of the display 2 and 4 (the number of lines of the source and the gate), and the selected signal is provided to the controller 110. Accordingly, the controller 110 stores and manages the coordinate values corresponding to the panel signal.

The average value detection frequency adjusting unit 143 adjusts the average value detection frequency for the panel signal output from the input device 250 based on the screen resolution information of the

display device

2 or 4 provided from the control unit 110. When the screen resolution is changed to a high resolution, the average number of times of detection is adjusted to be larger than a previously set value. On the contrary, when the screen resolution is changed to a low resolution, the average number of times of detection is adjusted to be smaller than a previously set value.

In addition, the average value detector 142 detects the average value of the panel signal transmitted from the input device 250 based on the average value detection frequency adjusted by the average value detection frequency adjustment unit 143. The detected average value is transmitted to the adjusted panel signal generator 144.

The adjusted panel signal generator 144 uses the average information of the position information of the display screen changed by the changed screen resolution or the virtual scroll of the

display apparatus

2 or 4 provided from the controller 110 and the currently input panel signal. To generate an adjusted panel signal.

At this time, in the present invention, the first input device 250-1 and the second input device 250-2 are provided. Therefore, the input device driver 140 controls the signal of the first input device 250-1. Signal control of the second input device 250-2 is performed.

That is, the first input device 250-1 and the second input device 250-2 alternately control the input device driver 140 by the control of the time controller 125 and the controller 110. )).

Alternatingly connecting means processing the signal generated by the first input device 250-1 and then processing the signal generated by the second input device. 1) It processes the signal of 250-2.

And this time division is divided into very small time, such as one tenth of a second to one thousandth of a second or one millionth of a second, so that when a user inputs information by a human hand, it can cope with enough.

Of course, the signal of the input device may be alternately processed as in the embodiment of the present invention, but it is natural that the input device 250-1 and 250-2 may be respectively provided to control and process the input device signal. Do.

31 is a flowchart showing the present invention.

When the display device of the present invention is operated, the main body control unit 105 is also operated to drive each device (step 400).

The controller 110 in the main body controller 105 divides the screen display data or the received screen display data stored in the memory 120. In this case, the function is controlled by the control unit 105 and the display driver 130. The controller 125 performs this operation (see the description of FIGS. 28 and 29).

Therefore, the main body controller 105 divides the screen and transmits screen data information corresponding to the first display and the second display, respectively (step 302).

Then, the input device driver 140 drives the first input device 250-1 by the switching device 145 of FIG. 30. That is, it controls the information output from the first input device (step 404) and controls the information output from the first input device according to the screen display information of the first display 2 (step 406). The method of controlling the input device according to the display information follows the method of FIG. 30.

Similarly, the switching device 145 controls the input device driver to output an output signal from the second input device (step 408), and controls the signal of the second input device according to the screen display information of the second display. Step) This step also follows the method of FIG.

If there is no stop command, the main body controller continuously divides the screen and drives each input device, but if there is a stop command, the series of performing functions ends (steps 412 and 414).

That is, in the present invention, the input device driver controls the information output from the first input device according to the screen information of the first display and controls the information output from the second input device according to the screen information of the second display. By repeating the above control execution of the input device driver, the two input devices are controlled as one input device.

Example 2

32 to 37 show another embodiment of the sliding structure.

32 is a diagram illustrating a state before the screen is expanded by sliding.

As shown in the figure, the display 2 mounted on the panel housing 20 located above is shown. Then, the speaker 101 used during the call and the microphone 102 used during the phone call are mounted so that the mobile phone functions in the above state. In addition, the selection button 100 or the like is also mounted.

Of course, when the portable display device of the present invention needs to hear a loud sound in order to be used as a multimedia device, a separate speaker may be mounted on the 100 object. A protective cover 51 serving as a cover for protecting the side of the joint 8 of the display 2 is provided.

33 is a view showing a state of sliding in the left and right directions.

As shown in the drawing, when the upper panel housing 20 is slid to the left and right directions, the lower display 4 mounted to the lower panel housing 40 appears. And, the sliding movement is made through the sliding groove (50a) provided on the inner side of the housing 50.

In addition, another cover 23 is provided on the opposite side of the joint 8 in the upper panel housing 20, and the protective cover 23 protects the side of the joint 8 of the lower display 4.

That is, the cover 23 formed in the outer wall shape provided on the upper panel housing 20 protects the side surface of the lower display 4, and the cover 51 provided on the lower panel housing 40 is the upper display 2. Protect the seam side of the.

In the figure, the inner side 51a of the cover or outer wall 51 protects the side of the seam of the upper display 2.

Accordingly, the

protective cover

23, 51 protects the side surfaces of the

display

2 and 4 joints while the upper and lower displays overlap, and the side surfaces of the

display

2 and 4 joints are moved when the upper and lower displays slide. There is no protection.

That is, as the display slides, the protective covers 23 and 51 protecting the side surfaces of the

joints

2 and 4 move together.

34 is a view showing a state in which the sliding movement in the vertical direction.

When the upper panel housing 20 is slidably moved in the left and right directions and then slidably moved in the vertical direction again, the upper and

lower displays

2 and 4 have the same height and are adjacent to each other.

35 and 36 are views illustrating a state in which the upper and lower panel housings are separated.

35 shows the upper panel housing 20, and FIG. 36 shows the housing 50 and the lower panel housing 40.

As shown in the figure, the sliding protrusion 21 provided in the upper panel housing 20 is coupled to the sliding groove 50a, thereby coupling and sliding the upper and

lower panel housings

20 and 40.

On the other hand, the grooves 50a provided on both side surfaces of the lower panel housing 40, that is, the inner sidewalls of the housing 50, have a curved shape at the joint portion 8. Therefore, when the upper and

lower panel housings

20 and 40 move vertically, the curved panel moves.

37 is a view showing a sliding structure.

The figure above the arrow in FIG. 37 is a figure with the upper and

lower displays

2 and 4 superimposed, and the figure under an arrow is a figure with the display unfolded.

As shown in the drawing, since the sliding groove 50a has a curved shape in the joint portion 8, the panel housings 20 and 40 move linearly when they move left and right, but when they move up and down, they move. .

In addition, the inner surface 51a of the lid 51 or the cover 23 provided on the upper panel housing may have a shaving curved surface shape, and thus the panel housing 20 which abuts with the inner surfaces of the lids 51 and 23 ( The

side walls

20a and 40a of the 40 also have a curved shape. Naturally, the

side walls

20a and 40a are portions having seams.

38 is a view showing the upper and

lower panel housings

20 and 40 overlapping each other. In the overlapped state, the speaker 101 and the microphone 102 which are used at the time of making a call are provided.

In addition, a handle 45 is provided on the protective cover 43 that protects the side surface of the joint 8 of the upper display 2. The handle 45 has a long protrusion or a long groove shape on the surface of the cover 43 so as to be easily held by the hand when the outer wall or the cover 43 is gripped and moved by hand.

In addition, the cover 43 connected to the lower panel housing 40 protects the side surface of the joint part 8 of the upper display 2.

39 is a view of a state in which the lower panel housing 40 is slid. When the lower panel housing 40 is slid and moved as shown in the drawing, the protective cover 43 does not protect the upper display seam 8 side.

In addition, the sliding protrusion 50a formed on the inner surface of the housing 50 also has the shape of a curvature. In other words, when the lower panel housing 40 moves left and right, the linear panel moves, but when the lower panel housing 40 moves, the lower panel housing 40 performs the curved motion.

Therefore, as shown in FIG. 37, the inner surface of the cover 43 has a curved shape, and the side wall of the joint portion of the panel housing 20 which contacts the inner surface of the cover 43 also has a curved shape.

Meanwhile, although omitted in the drawing, when the

displays

2 and 4 are stacked up and down, the side of the seam of the lower display 4 extends to the housing 50 or the upper panel housing 20 to be protected. Of course.

40 is a diagram with the display fully extended. That is, in the state where the upper and

lower panel housings

20 and 40 overlap (FIG. 38), the lower panel housing 40 slides in the left and right directions (FIG. 39), and then the two panels (2) are curved in the upward direction. 4 is fully expanded, resulting in two

displays

2 and 4 having the same height (FIG. 40).

Example 3

41 through 52 are diagrams of yet another embodiment.

41 is a view of another embodiment in which the panel housing is in a stacked state.

The upper panel housing slides in the direction of arrow A, and the seam 8 of the upper display 2 is protected by the lid 43.

42 is a state in which the upper panel housing is slid and expanded.

As the panel housings 20 and 40 are expanded, the cover 43 is not covered by the joint part 8, and the lower display 4 mounted on the lower panel housing 40 is visible.

43 is a diagram with two displays fully extended.

In FIG. 42, when the upper panel housing 20 moves in the direction of arrow B, that is, downward, the state of FIG. 43 is obtained.

In the present invention, the lower cover 43a is configured to move in the vertical direction from the side of the lower panel housing 40. That is, when the lower cover 43a slides downward, the upper panel housing 20 on the top of the lower cover 43a also moves downward.

That is, the lower cover 43a is provided at the side of the lower panel housing 40 to protect the seam 8 of the lower display 4. However, as the lower cover 43a is moved downward, the lower display 4 does not protect the seam, and as a result, the upper and

lower displays

2 and 4 are adjacent to each other.

44 and 45 are views illustrating a state in which the upper panel housing is removed.

As shown in the figure, a projection plate 71 is provided on the upper end of the lower cover 43a as a sliding means. The protrusion plate 71 allows the upper panel housing 20 to slide while supporting the upper panel housing 20, and the protrusion 72 plays a role in sliding movement.

That is, the basic structure of the embodiment of the present invention is that the plate-shaped structure made of metal, alloy or reinforced plastic supports and moves the upper panel housing.

In addition, the protrusion plate 71 is firmly fixed to the upper end of the lower cover 43a through the plate fixing part 75. At this time, the fixing portion 75 is fixed through the projection plate groove 73 provided in the projection plate 71, the projection plate groove 73 is formed in the recess 74.

The recessed portion 74 is formed lower than the surface of the protrusion plate 71 so that the fixing portion 75 fixed to the protrusion plate 71 does not become higher than the surface of the protrusion plate 71.

At this time, the projection plate 71 and the fixing portion 75 which is a sliding means is made of a metal or alloy, etc. to make it durable.

46 shows the lower part of the upper panel housing.

A leg 20b is provided below the upper panel housing 20 so as to be formed higher than the bottom surface of the upper panel housing. Therefore, a space in which the protrusion plate 71 is slid and moved in the bottom portion of the upper panel housing 20 is made.

A bottom groove 80 is formed at the bottom of the upper panel housing 20, and the protrusion 72 of the protrusion plate 71 is engaged with the bottom groove 80 so as to slide.

And the bottom groove 80 is made by the bottom plate (81).

47 and 48 are views of the bottom plate removed from the upper panel housing.

Steps 84 are provided at the bottom of the upper panel housing to form a predetermined space and a hook 83 is formed in the formed space, and a ring 82 formed behind the bottom plate 81 is firmly fixed to the hook 83.

49 and 50 are views with the lower cover removed.

When the lower cover 43a is removed from the lower panel housing 40, the vertical movement means provided in the joint portion of the lower panel housing 40 appears. The vertical movement means allows the lower cover 43a to slide in the upper and lower directions in the lower panel housing 40.

In addition, the vertical movement means is composed of a support plate 90, the spring device 91 is further provided on both sides of the support plate 90. Inner grooves 90a are provided at both sides of the support plate 90, and an inner bottom 92 is also provided.

51 and 52 are views showing the coupling portion of the lower cover.

In the figure it can be seen that the side of the lower cover 43a is coupled to the side of the panel housing 40.

Cover spaces 94 are formed on both side surfaces of the lower cover 43a, and coupling portions 95 are provided in the cover space 94. The coupling portion 95 is formed of a head 95a and an attachment portion 95b, and the coupling portion 95 is fixed to the internal space 94 through the attachment portion 95b. It will be fixed with adhesives, screws, engaging projections, etc. on the marked part.)

Therefore, the coupling portion 95 is engaged with the inner groove (90a) on both sides of the support plate 90 to move. The movement of the coupling portion 95 is limited by the inner bottom 92. In other words, the lower lid 43a is prevented from falling downward more than necessary. And, by the spring 91 will be able to easily move back to the lower cover (43a).

Example 4

53 is a sectional view of two panel housings.

As shown in the drawing, the panel housings 20 and 40 may have different thicknesses. In the case of FIGS. 32 to 34, the upper panel housing 20 may have a thinner structure. In the present invention, the panel housings 20 and 40 serve as cases in the portable display device.

The display 2 and the input device 200 are directly provided on the upper portion of the bottom portion of the thinly formed panel housing 20 (indicated by the arrows "0" in the drawing).

Then, parts such as a battery or a main body control unit are provided in the main body part 25 provided at the lower part of the display of the panel housing 40 formed thickly.

Naturally, the supporting

parts

26 and 46 supporting the display 2 and the like may be provided.

12 also shows a cross-sectional view of one panel housing 20 for convenience of illustration. The reason for this is that another panel housing 40 is similarly provided to form a symmetrical structure.

54 is an embodiment diagram showing an example of such a symmetrical structure. Naturally, this symmetrical structure is applied to all of FIGS. 12 to 18.

However, the symmetrical structure does not mean that even the parts mounted on each panel housing are the same. That is, the

display

2, 4, the

input device

200, 400, and the parts related to the display and the input device are provided in both

panel housings

20, 40.

However, parts such as the main body control unit 105 and the battery (not shown for convenience) shown in FIG. 27 need not be provided in both panel housings. The battery 25 is mounted, and the main body control part 105 can be mounted to the other parts 45.

On the other hand, when the panel housing is unfolded as shown in Figs. 53 and 54, a protective film 14 may be provided between the two

displays

2 and 4, but as shown in the previous embodiment, the

display

2 and 4 may be provided. Naturally, the

panel housing sidewalls

20a and 40a may be provided between them. At this time, the thickness of the panel housing sidewall is preferably not more than 1.5mm.

55 to 57 show an embodiment with a frame housing.

As shown in FIG. 55, the lower panel housing 20 is equipped with a battery or a main body circuit portion, and a frame housing 20-1 or a bracket 20-1 is mounted on the upper panel housing. At this time, the display is mounted on the frame housing 20-1.

When the display 2 is mounted on the frame housing 20-1, the display 2 is mounted closer to the joint 8. Here, the seam is a portion where the

displays

2 and 4 are interconnected. That is, when a portion of the display 2 on which the screen is displayed is called an active area 2-1, the active area 2-1 is larger than the opposite side of the joint of the frame housing 20-1. It is mounted closer to the seam 8.

And the protection plate or the input device 200 is mounted on the top. The area in which information can be input from the input device 200 may be referred to as an active area 200-1, which is indicated by white color at 200 in FIG. 55.

The active area 200-1 of the input device is also mounted closer to the seam than to the seam opposite.

In FIG. 55, the L-L direction cross section is FIG. 56, and the K-K direction cross section is FIG. 57. In the drawings, it is shown that a protective plate or an input device is mounted around the frame housing 20-1. In addition, the supporting part 30-1 is mounted between the display 2 and the frame housing to support the display or absorb shock.

In the drawing, the lower part of the frame housing 20-1 may be partially cut. (As shown in FIG. 56 and FIG. 57, as indicated by D, the cut may be possible.)

58 shows a structure in which the displays are adjacent to each other.

This is a diagram of an embodiment showing that when the two

panel housings

20 and 40 are adjacent to each other, the height of one panel housing is higher than the height of the other panel housing.

In the drawing, the panel housing 20 having a low height is directly mounted on the lower portion of the panel housing 20. At this time, a support part 30-1 may be provided between the panel housing lower portion and the display 20. The support part may also serve as a protective plate for absorbing shock. The protective plate 30-1 may be provided as a whole between the panel housing display, or may be partially provided between the display and the panel housing.

In addition, the distance between the lower panel housing 20 and the display 2 is within 2mm. The length H1 from the bottom of the panel housing to the protective plate or the input device 200 is also within 10 mm. However, when thinning is realized, the display can be within 1.5mm, the panel housing thickness within 1mm, and the input device including the protective plate within 1.5mm in thickness. H1 can be within 4mm and within 5mm. That is, the size of H1 may be different depending on the case of a mobile phone and a tablet PC.

On the other hand, the display may be mounted directly under the panel housing 20, in which case the distance between the panel housing lower and the display is 0 mm.

In addition, the height H2 of the thicker panel housing may be within 8-12 mm or 16-25 mm depending on the situation.

If H1 is 3-5mm and H2 is 7 15mm, the ratio of H1 / H2 is 0.20 (3/15) to 0.71 (5/7).

In addition, the protection means 14 is provided in the portion where the display is interconnected, the protection means may be a separate protective plate or a protective film, may be a side wall connected to the

panel housing

20, 40, frame housing ( It may also be a side wall connected to 40-1).

In addition, the thickness of the perforated plate or the side wall at the portion where the display is connected, and the arrangement of the display and the input device according to another embodiment of the present invention.

59 to 62 illustrate a method of mounting a display.

When a part of the display 2, which is made of glass or plastic and represents a screen, is referred to as a display panel 2a, and the backlight 2b is provided on the rear surface of the display panel 2a, the OLED element does not have a backlight 2b. . In the drawings, the driver circuit is omitted for convenience of illustration.

In this case, when the display is provided in the panel housing 20 or the frame housing 20-1, the display may be provided in a state in which the display is mounted on the chassis or the apparatus as shown in FIGS. 59 and 60. There is a display panel 2a and a backlight 2b, and if it is an OLED, there is only a display panel 2a. (The driving part is a common part and thus is omitted from the description.)

61 and 62, the display may be directly mounted to the panel housing 20 or the frame housing 20-1.

In this case, an interval between the display 2 and the panel housing 20 or the frame housing 20-1 may be 2 mm or less, and in some cases, no gap may be 0 mm. And the supporting plate (30-1) is provided between the intervals.

And, when the display 2 is mounted directly to the panel housing 20 or the frame housing 20-1, another embodiment of the OLED device can be considered. That is, the figure above the arrow in FIG. 62 shows that the OLED element can be mounted directly to the housing 20, 20-1.

Yet another embodiment is shown in the figure below the arrow in FIG. In other words, the panel housing 20 or the frame housing 20-1 (hatched portion in the figure below the arrow) can replace the function of the OLED lower substrate (No. 52 in FIG. 9). In some cases, the panel housing substrate or the frame housing substrate may be made of a metal material. In this case, the panel housing 20 or the frame housing 20-1 may replace one substrate of the OLED. By doing so, the thickness of the display device can be made thinner.

63 is a diagram of an embodiment when using as a mobile phone.

While the speaker 101 and the microphone 102 are used during the call, the input keyboard 256 can be displayed on the screen when a telephone number or the like is input. Although the screen is in the form of a plurality of boxes (Box), it is obvious that a number character symbol or the like is displayed in the box.

And a simple button 100 may be provided. Naturally, a separate speaker that can make a loud sound at the position of the button 100 may be provided.

64 is a diagram of an embodiment when used for character input or the like.

When the two

displays

2 and 4 are extended to use various contents such as data communication and information use, the input keyboard 255 may be displayed on only one screen. In this case, the input keyboard 255 displays a keyboard shape that can function as a keyboard input function in which both Korean alphabet and alphabet are displayed. Then, when the user touches a portion where a desired letter is displayed, the

input apparatus

200 or 400 may recognize the information.

Meanwhile, in the present invention, although the capacitive type and the resistive type input devices are taken as an example, it is obvious that the input device for inputting information on a flat plate may be used as it is.

When the portable display device of the present invention is operated, the sensor 135 of FIG. 27 determines whether the panel housings 20 and 40 are coupled. Here, the coupled state means that the upper panel housing 20 and the lower panel housing 40 are stacked up and down.

When the display is selected to display the input keyboard on the screen (step 455), it is determined by the sensor 135 whether it is in the engaged state (step 460).

If the channel housing is in the coupled state, the type A keyboard is displayed on the screen (step 470). At this time, the type A keyboard is the type shown in the embodiment of FIG. If not, the B-type keyboard is displayed on the screen (step 465). At this time, the B-type keyboard is the type shown in the embodiment of FIG.

If the user selects to exit, the system is shut down (step 475).

As described above, it is possible to automatically control the state displayed on the screen according to the coupling state of the upper and

lower panel housings

20 and 40.

66 is a flowchart illustrating a coupling sensor.

When the portable display device of the present invention is operated, it is determined whether the panel housings 20 and 40 are coupled by the sensor 135 shown in the block diagram of FIG. 27 (step 485).

Once assembled, the display mounted on the top panel housing is driven. A screen format for driving one display is selected (step 490). If not combined, both displays are driven, and a screen format for driving two displays is selected. (Step 495)

The display device of the present invention can be used with only one screen and can be used with only two screens. Therefore, the screen format for displaying one screen and the screen format for displaying two screens are stored in the memory 120 of the main body controller 105 shown in FIG. 27. In addition, the controller 110 selects a screen format suitable for the detection of the sensor 135.

When the screen is selected, the controller 110 controls the screen display according to the selected screen. In other words, the control mode when displaying one screen is different from the control mode when displaying two screens.

FIG. 69 is a view showing another embodiment of the coupling part, in which the shape of the coupling head 95a is changed to a protrusion shape. That is, the coupling protrusion 95c is formed, and the coupling protrusion 95c is coupled to the elastic support plate 91a of FIG. 67.

The upper and lower positions of the upper and

lower panel housings

20 and 40 are effectively fixed by the coupling protrusion 95c and the elastic support plate 91a. In other words, the upper and

lower panel housings

20 and 40 are easily fixed in the upper and lower positions, and are not fixed in the intermediate stage positions.

70 is a diagram illustrating an upper and lower error of the upper and lower panel housings. That is, the embodiment when the bottom support plate 93 is provided as shown in FIG. In principle, when the upper and

lower panel housings

20 and 40 are unfolded, the mutual heights of the

displays

2 and 4 and the panel housings 20 and 40 are the same.

However, there can be differences in height above and below the value. At this time, the value should not exceed about 2mm or 2.5mm. That is, it means that the upper and

lower panel housings

20 and 40 go up or down by about 1.5 mm or 2 mm in the vertical movement, and then have the same height.

71 to 72 are views illustrating a lower panel housing and a projection board according to still another embodiment.

In this embodiment, when the lower panel housing 20 moves while supporting the upper panel housing 40, the lower panel housing 20 has a structure that further includes a plate-shaped moving support separately for rigidity.

In the present invention, the projection means 76 is provided as the moving means. In addition, the protrusion is made of steel, stainless steel or alloy as a metal material to increase the robustness.

In the figure it is shown that the projection plate 76, which is another embodiment of the sliding means on the top of the lower cover (43a) is provided. Therefore, the upper panel housing 20 is mounted on the top of the projection board 76, and the projection board 76 may be provided with one or two fixing protrusions 76a, and up to about three depending on the situation. Can be.

In FIG. 71, the protruding plate 76 is slid outwardly in FIG. 72. That is, the projection board 76 has a structure that is made wider than the width (width) of the lower cover (43a).

In the present invention, the protrusion plate 76 substantially supports the upper panel housing 20, so that the width of the protrusion plate 76 is wider than the width of the lower cover 43a to make the upper panel housing 20 more firm. To support it.

73 is a view showing the projection plate 76, and a fixing projection 76b is further provided below the projection plate. The lower cover 43a supports the protrusion plate 76 through the fixing protrusion 76b.

71 and 73 are embodiments of a principle in which the panel housing is slidably moved in the left and right directions, and the up and down movement is performed by the movement of the protective cover as in the embodiment of FIGS. 41 to 43.

As shown in the figure, a square groove 77 is provided in the lower cover 43a, and a leaf spring 77a is provided in the square groove as shown in the drawing.

74 is a view illustrating a state in which the fixing protrusion 76b is slidably moved. Since the plate spring (77a) is provided so that the projection plate 76 is in the initial position and the later position, not in the middle position when sliding the top of the lower cover (43a).

FIG. 75 is a detailed view of the square groove 77. The leaf springs 77a are provided at both sides of the square groove 77 provided in the lower cover 43a, and the fixing projections of the protrusion 76 are interposed therebetween. 76b is made to slide. In the figure, the lower part of the projection board 76 is shown and shown.

In addition, the lower panel housing 40 described in the embodiments of FIGS. 71 to 75 is similar to the embodiment of the upper and

lower panel housings

20 and 40 described in FIGS. 41 to 52 and FIGS. 67 to 70. Naturally, it can be applied as it is.

76 is a view of still another embodiment in which the protrusion plate is slid.

In the drawings, a moving bar 78 and a moving shaft 78a are provided below the protrusion plate 76. Therefore, the protrusion plate 76 is moved from the upper portion of the lower cover 43a by the moving bar 78 and the moving shaft 78a.

77 and 78 are views showing the principle of movement by the moving bar.

FIG. 77 is a view showing the projection board 76 with the moving bar 78, and FIG. 78 is a view showing the movement of the projection board 76. As shown in FIG.

In the drawings, the left and right direction movement is shown in one step, and the up and down direction movement is shown in this step.

The left and right movements are moved by the movement bar 78 and the movement shaft 78a and are movable by the elasticity of the movement spring 78b.

In addition, although not shown in the drawings for convenience, it is obvious that there is a locking means for preventing the projection board 76 from deviating too far outward of the panel housing 40. 74 and 75 embodiments may be applied as appropriate locking means in this embodiment.

The vertical movement is also moved by the movement bar 78 and the movement shaft 78a and is movable by the elasticity of the movement spring 78b. Here, the moving shaft 78a has an axis connecting the moving bar and the moving bar 78, and there is also an axis for fixing the moving bar 78 to the protruding plate 76, and the moving bar 78 is fixed to the panel housing 40. Of course, there is an axis.

79 to 81 are views showing the lower part of the upper panel housing.

In the figure, the bottom groove 80 is provided at the bottom of the upper panel housing 20, the bottom groove 80 is further provided with a fixing spring 81a, one at the front and one at the rear. Of course, the fixed spring may be used in the form of a leaf spring. The position of the upper panel housing 20 is fixed by the action of the fixing spring 81a.

That is, when the upper panel housing 20 is positioned in the state of FIG. 41 of the previous embodiment, a fixing spring close to E " acts to fix the upper panel housing 20, and FIGs. In the state, a fixing spring provided close to the joint 8 acts to fix the upper panel housing 20.

In other words, when the upper panel housing 20 moves with the lower panel housing 40, the upper panel housing 20 is reliably positioned at a desired position by a spring action.

In addition, when there are two fixing protrusions 76a on the top of the protrusion plate 76, the fixing spring 81a is positioned between the two fixing protrusions 76a to further increase the firmness.

On the other hand, the portion denoted by E "may be referred to as the end of the bottom groove 80, as well as serves to push the end portion (part denoted by E) fixing protrusion 76a of the bottom groove 80, The upper panel housing 20 and the lower panel housing 40 and the projection plate 76 serves to determine the mutual position.

Therefore, each design value reflects the design. In this case, since the value varies depending on the size and specification of the panel housing, the present invention does not need to represent each design value one by one, but only represents the principle.

FIG. 80 is a view showing an embodiment in which the portion indicated by E in FIG. 79 is replaced with the moving support plate 81b.

As shown in the figure, a support spring 81c is provided on the rear side of the movable support plate 81b, and a support groove 81d on which the support spring 81c is mounted. And as shown in Figure 55a, the fixing projection (76a) is located between the fixing spring 81a and the movable support plate (81b).

However, at this time, the moving support plate 81b may be pushed in the direction of the arrow. This is to give an error range that can adjust the degree of close contact between the two

panel housings

20, 40, so as to withstand more impact.

That is, the state in which the two

panel housings

20 and 40 are completely in contact with each other in FIG. 81 becomes a state in which the movable support plate 81b is not pushed in the direction of the arrow in FIG. 80, and the two panel housings 20 in 81. 40, the state in which the moving support plate 81b is pushed in the arrow direction is shown in FIG.

In addition, if the value of the degree that the two panel housings can fall to the maximum, a value, the a value is appropriate within 2.5mm. That is, the value a represents a range of distances between two

panel housings

20 and 40 that can fall during vertical movement.

82 to 84 are views of the embodiment provided with the side protuberances.

FIG. 82 is a view showing a side protrusion 79 provided with side protrusions 79a. That is, another form of protrusion plate for supporting the upper panel housing 20 in the lower panel housing 40.

As shown in the figure, the protrusions supporting the upper panel housing 20 are on the side, and thus the side protrusions 79a are provided on the side protrusions 79.

FIG. 83 is a view illustrating a form in which the width of the side protrusion board 79 is wider than the width of the lower cover 43a. In this case, although not shown in the drawings, as shown in the embodiment of FIGS. 74 to 75, the fixing protrusion 76b is provided under the side protrusion plate 79. The side protrusion plate 79 is moved from the upper end of the lower cover 43a to the left and right directions by the fixing protrusion.

In the drawing of FIG. 83, the fixing protrusion 76b is not shown for convenience and the position thereof is shown by the dotted line.

84 is a view showing the upper panel housing 20 having side grooves. In order to engage the side projection (79a) it is provided with a side groove (86a) in the upper panel housing (20).

That is, as shown in the drawing, a lower space 85 is formed in the lower side of the upper panel housing 20, which is a space for moving the side protrusion plate, and the side grooves (bottom side 86) formed on both side surfaces of the lower space 85 ( 86a).

At this time, the side groove (86a) is further provided with a spring, such as a leaf spring, as in the previous embodiment, it is of course possible to ensure the position where the upper panel housing and the lower panel housing are mutually located.

Example 7

As shown in the figure, the height of the protective covers 23 and 43 is lowered, and instead, the portion engaging with the protective covers 23 and 43 is also adjusted to the height.

The figure conceptually illustrates the principle of sliding movement, and the upper and lower panel housings 20 are slidably moved in the left and right directions in a stacked state, and are slidably moved in the vertical direction again.

When the two panel housings are stacked, the protective covers 23 and 43 are covered and mutually supported.

In this way, the height of the protective cover (23) (43) can be lowered to improve the design, and when the two panel housings (20) and (40) are unfolded, the upper panel housing (20) is more firmly supported. You can also build a structure to do it.

As shown in the figure, the projection board 76 is moved in the jaw direction and the vertical direction by the moving bar 78 and the moving shaft 78a.

As shown in FIG. 86, when the moving bar 78 is bent, as shown in FIG. 87, the protrusions 76 move outward. And when the moving bar 78 is in the down state, as shown in Figure 88, the projection plate 76 is moved downward. In addition, the movement of the movement bar 78 is controlled by the action of the cylinder 78b.

As described in the foregoing embodiment, the width of the protrusion 76 is wider than that of the protective cover 43a or the lid support 43b. The protrusion 76 is supported more effectively than the upper panel housing 20. To do that.

As shown in the present invention so far, the projection plate 76, the moving bar 78 and the parts integrally attached thereto are all made of an alloy of metal to enhance the robustness.

As described above, when the lower panel housing 20 moves while supporting the upper panel housing 40, the lower panel housing 20 further includes a plate-shaped moving support for robustness.

Example 8

As shown in the figure, the upper panel housing 20 has a structure that makes both edges longer. In doing so, the length of the protective cover 43 provided in the lower panel housing 40 is also shortened.

In FIG. 89, the upper and

lower panel housings

20 and 40 are stacked. When the upper panel housing 20 is moved in the direction of the arrow, the upper and

lower panel housings

20 and 40 are stacked.

In this case, in FIG. 90, both edges of the upper panel housing 20 are longer. That is, the length of the S "is as much as the width of the protective cover 43 when the degree of lengthening is S".

Of course, S ″ may be formed shorter than the width of the protective cover. In this case, the shape of the protective cover is designed and manufactured to engage with it. Various design variations are not shown for convenience.

The state moved downward in FIG. 90 is the state in which the two panel housings are fully unfolded in FIG. 91.

92 and 93 are views illustrating the lower panel housing.

That is, the drawing is a structure of the lower panel housing according to the embodiment of FIGS. 89 to 91. That is, the protrusion plate 76 is formed in a "-shape, and is further extended in both edge directions. Therefore, the position of the fixing protrusion 76a is also moved inward.

On the other hand, the lower cover 43a also extends in both edge directions to have a "-shaped shape.

FIG. 89 shows the state of 92, and when the protrusion 76 moves outward, the state of FIG. 90 becomes FIG. That is, as in the previous embodiment, the fixing protrusion 76a of the protrusion plate 76 supports and moves the upper panel housing 20.

In addition, the projection head 97a is positioned between the spring protrusion 307b and the curved housing 308 so that the protrusion head 97a moves up and down along the curved shape. That is, curved housing 308. The spring protrusion 307b, the side plate 307, and the supporting portion 43a all move downward, but the protrusion head 97a and the lower panel housing 40 do not move relatively downward.

In addition, the upper panel housing 20 and the lower panel housing 40 move upward and downward in a curve by the movement of the projection head 97a.

In the figure, the protruding head 97a moves in the direction of the arrow, and of course, moves again in the direction opposite to the arrow.

On the other hand, the coupling protrusion 97 is also formed inside the side wall of the lower panel housing 40, the spring device 97b is wrapped as shown in the figure. A jaw 97c is also provided to prevent the engaging projection 97 from escaping the side wall of the lower panel housing 40.

And, because of the spring device (97b) the projection head (97a) is able to move the surface of the spring projection (307b) of the curved shape. That is, the coupling protrusion 97 may move left and right about the side wall of the lower panel housing 40.

The bottom plate 330 is coupled to the lower portion of the upper panel housing 20, and the sliding groove 80 is inserted to allow the sliding protrusion 332 of the bottom plate 330 to be inserted into the guide groove 314b of the plate 310.

That is, the bottom plate 300 and the plate 310 slides and moves, and the support plate 300 and the plate 310 slide. Each

spring assembly

320 and 325 is then compressed, as described in FIGS. 95 and 97.

The sliding movement in the left and right directions is made possible by moving the fixing groove 311 through the bottom groove (80).

Meanwhile, when the upper panel housing 20 is slid to the left and right directions as far as possible, the upper panel housing 20 is moved in the vertical direction, thereby bringing the state of FIG. 103. This movement is because the projection head 97a moves between the spring projection 307b and the curved housing 308 as in FIG.

That is, when a force is applied, the upper panel housing 20 is moved downward by the force of the spring protrusion 307b, so that the upper panel housing 20 is in close contact with the lower panel housing 40. As a result, the two displays 2 (4) becomes adjacent to each other as shown in FIG.

104 is a view showing the cross-sectional shape of the bottom plate.

As shown in the figure, the bottom plate 330 is connected to the lower portion of the upper panel housing 20 and mounted directly under the upper panel housing 20. Therefore, the bottom plate 330 is made of a material such as metal. In addition, sliding protrusions 332 are formed at both ends of the bottom plate 330, and the bottom grooves 80 are formed to be movable by inserting and coupling the sliding protrusions 332 and the fixing grooves 311 of the plate 310.

In the case of FIG. 105, the upper panel housing 20 moves up and down with respect to the lower panel housing 40 in a direction opposite to the curved shape (arrow posh) shown on the right side. That is, when the upper panel housing 20 and the lower panel housing 40 move up and down, the linear panel moves in a curved motion rather than linearly. As a result, the upper panel housing 20 and the lower panel housing 40 mutually move up and down. The distance will be close and then close again.

At this time, the distance to be separated is not good too large and usually 0.5mm is suitable, but may be from 1mm to 3mm. And this separation distance is determined by the size of the left and right width of the spring projection (307b).

106 illustrates a spring protrusion 307b having a protruding curved shape, and thus the upper panel housing 20 and the lower panel housing 40 also move in the opposite direction.

That is, when the upper panel housing 20 moves below the lower panel housing 40, the upper panel housing 20 is positioned slightly higher than the lower panel housing 40 and then moves downward. Then, as a result, the upper panel housing and the lower panel housing come into close contact with each other at the same height.

In this case, the distance from the high position is usually about 0.5mm is enough, but within 3mm may be appropriate.

Conversely, when the lower panel housing 20 returns to its original position, it moves along the opposite path.

On the other hand, as shown in the drawing, the protrusion 307d can be taken as a design structure that is easily contracted by adding a separate spring device.

107 is a view showing the movement of the upper and lower panel housings.

As shown in the figure, the upper and

lower panel housings

20 and 40 are slidably moved in the left and right directions ((A) state in the drawing), and are in a state before moving in the vertical direction (B) state in the drawing. This movement takes place in the process of compressing the

spring assembly

320, 325 by applying pressure.

Further, applying a further moving pressure causes the upper panel housing 20 to rise slightly above the lower panel housing 40 ((C) state in the drawing). About 3 mm is suitable, and the distance is determined by the size of the projection 307d in FIG.

The upper panel housing 20 is slightly raised and then moved downwards ((D) state in the drawing). In this case, the upper panel housing 20 and the lower panel housing 40 move in a slightly spaced state. At this time, there is a suitable separation distance and may be very small as 0.05 mm, but 0.5 to 3 mm is suitable.

In addition, through the above process, the display is in a state of being adjacent to each other ((E) state in the drawing). This process can also be pressurized and reversed.

Comparing such a situation in the drawing, the state where the projection head 97a is located below in FIGS. 105 and 106 (the projection head located below in solid lines in FIGS. 35 and 36 is shown in solid lines) is the state (B) in FIG. The state where the projection head 97a is located upward (shown by the dashed-dotted line in the upper part in FIGS. 35 and 36) is the state (E) in FIG. 107. And this process can be repeated as pressure is applied and released.

108-111 illustrate an embodiment of a spring assembly.

In the present invention, it is possible to compress by applying a force and to restore again when the force is released, or to use a conventional spring composite that is expanded and restored when the force is released. Naturally, it is possible to use a variety of spring composites that are capable of overstressing or restoring or expanding and restoring.

108 The two sliding

bars

320b and 320c coupled to the coil spring 320a are mutually slid by the sliding means 320d, at which time the two sliding

bars

320b and 320c are moved by the coil spring 320a. Can be mutually compressed and expanded. Naturally, one of the sliding

bars

320b and 320c is coupled to the bottom plate 330 and the other to the plate 310.

109 is a principle that allows the plate 310 to move using the inclined bar 327a and the compression spring 327. That is, when the pressure is applied to the plate 310 and pushed upward, the compression spring 327 is compressed by the inclined bar 327a. When the pressure is released, the compression spring 327 is expanded to expand the plate 310 by the sliding groove or the sliding bar. Through 335 is restored to the original position.

110 and 111 is a spring assembly to enable compression and expansion by connecting a plurality of springs in the form of a semi-circular wire. That is, a plurality of semicircular wire springs 329b are connected to each other by a rotation hinge 329c to form a rotatable joint, and then, the fixing parts 329a and 329d are placed at both ends.

Of course, one of the fixing parts 329a and 329d is fixed to the plate 310 and the other to the bottom plate 330. In addition, when the sliding movement is applied to the movement of the plate 310 and the bottom plate 330, the wire spring 329b is compressed, and when the force is released, the wire spring 329c is expanded to expand the plate 310 and the bottom plate ( The position of 330 is to be restored.

Meanwhile, FIG. 111, which is another embodiment of a semicircular spring structure, is an example of a spring structure used when two panel housings have a large moving distance.

Example 10

112 to 115 are views illustrating the sliding movement principle. The process in which the spring composite 320 connected to the plate 310 is connected to the bottom plate of the upper panel housing 20 (the bottom plate of the upper panel housing is omitted) and the principles of the embodiments of FIGS. 94 to 103 may be applied. .) To allow the upper panel housing 20 and the lower panel housing 40 to slide in the left and right directions.

At this time, the spring complex repeats the restoration in expansion or contraction in expansion, it is made of accessories such as spring and has the force to make the sliding movement by elastic force.

In addition, the support plate 340 is further provided, the support plate 340 and the plate 310 may be moved together as an integral part. The shape of the support plate 340 may be deformed by applying the function of the protrusion plate 76 illustrated in FIGS. 92 and 93.

The backing plate 340 is mounted inside the lower panel housing 40 and moves to slide from the lower panel housing so that a part of the support plate 340 may come out. At this time, the principle that the support plate 340 sliding out of the lower panel housing 40 can also be applied to the principle that the plate 310 and the spring composite 320 is moved, or a conventional guide structure and spring The device can be used.

However, the principle of the operation of the support plate 340 in this embodiment is not described separately because the principle can be applied through the previous embodiment.

At this time, when the supporting plate 340 is partially out of the lower panel housing, it can make a structure that can support the supporting plate 340, this structure is the lower panel housing of Figure 85 to Figure 88 in the above embodiment The structure may be applied.

When the user of the display device pushes the upper panel housing 20 in the overlapping upper and lower panel housings (FIG. 112), the spring 310 is compressed or expanded and the upper and lower panel housings are expanded in the left and right directions. (Figure 113)

Further, when pushed further, the support plate 340 comes out, and thus, the plate 310 connected to the support plate also comes out of the lower panel housing boundary (FIG. 114), where the support plate 340 also comes out of the panel housing. The spring mounted on the backing plate is compressed or expanded.

Then, when the user pushes the upper panel housing downward, the upper panel housing and the lower panel housing are in the same state as each other (FIG. 115). For this purpose, the support plate 340 is in the lower panel housing 40. The plate 310 moves downward, so that the plate 310 also moves downward, so that the upper panel housing 20 supported by the plate 310 also descends.

At this time, the principle of the support plate 340 to move down can be implemented using the pressing side or expansion of the spring and the moving guide component.

On the other hand, when the upper and lower panel housings are in the same height, mutual coupling means or locking means exist to maintain the same height.

When the user of the display device releases the coupling means or the locking means, the spring used to move the support plate 340 is restored so that the upper panel housing is raised above the lower panel housing, and used to move in the left and right directions. The springs of the supporting plate 340 and the plate 310 are also restored so that the upper and lower panel housings overlap in the original state.

FIG. 116 is a view for explaining a principle in which the upper and lower panel housings move by side movement. Here, the support part 43C which supports the support plate 340, and the moving means 341 which move and use the support plate 340 mutually are provided. The moving unit 341 may be a component to which the principle of moving the plate and the bottom plate through the spring composite is applied.

On the other hand, when the panel housings 20 and 40 are unfolded and then moved in the vertical direction, one panel housing needs to have a thinner height in order to reduce the vertical movement distance. The thinner structure of the panel housing can be applied to the embodiments of FIGS. 53 and 58.

117 and 118 are views showing an outline of a lower panel housing state, and it can be seen that the shape of the protrusion 76 shown in FIGS. 92 and 93 is applied to the previous embodiment. 117 shows that the plate 310 and the support plate 340 are connected in one piece, and the support 43C moves downward, so that the support plate 340 moves downward. 117 is without the middle part of 23C of FIG.

Thus, in the case of FIG. 117 without the middle portion of 23c, the lid 23 described in FIG. 37 should be provided in the upper panel housing, and the use thereof is the same as the lid 23 of FIG.

FIG. 118 shows the backing plate 340 and plate 310 moving out of the lower panel housing boundary. As the structure moves outward, the upper panel housing can be moved downward.

119 and 120 are views of an embodiment provided with an extension.

32 to 40 is applied to the above embodiment, and further includes an extension portion 345 which comes out of the panel housing boundary to support each other more firmly in the state where the heights of the upper and lower panel housings are equal to each other. It will play a role.

At this time, the extension portion 345 is a structure that is capable of sliding movement through the spring device and the guide means in the both sides of the upper panel housing 20. Accordingly, in the state where the upper panel housing and the lower panel housing overlap, the extension part 345 enters the upper panel housing 20, and in the unfolded state, the extension part 345 comes out.

121 is a view showing an example of a coupling unit.

It is an example of the engaging

means

55, 55a or the locking means 55, 55a for maintaining the state in which the upper panel housing and the lower panel housing are unfolded and then the same height.

In the drawings, the upper and lower panel housings are provided with protrusions or grooves in contact with each other when the upper and lower panel housings are unfolded at the same height so as to have a coupling bearing force. In FIG. 121, it is a figure which shows the position of the engagement means or the locking means 55 and 55a, and it does not matter where the upper panel housing and the lower panel housing contact actually.

In addition, the object of the present invention can be achieved by taking the form of the groove and the protrusion to engage with each other.

FIG. 122 is a view illustrating a principle in which the lower panel housing 40 in the housing 50 slides in the left and right directions and moves in the upper direction so that the two panel housings are unfolded.

123 is a view showing the principle of such a movement, the bottom panel 81-1 is provided in the lower upper panel housing, the fixing groove 350 is moved through the projections on both sides of the bottom plate 81-1. .

In addition, the support plate 351 is formed integrally with the fixing groove 350 is provided with an extension support plate 352. In other words, the extended support plate 352 is further extended so that the lower panel housing 40 comes out of the boundary of the upper panel housing 20. The lower panel housing 40 moves upward through the

spring devices

353 and 353a. At this time, the moving means 352a is a spring composite to allow the support plate 351 and the extended support plate 352 to move left and right.

That is, when the lower panel housing 40 moves in the left and right directions, the bottom plate 81-1 and the fixing groove 350 are used. And, when the lower panel housing 40 comes out of the upper panel housing 20 boundary, the support plate 351 and the extended support plate 352 are used. In addition, the spring device (353, 353a) is used when the lower panel housing 40 is moved upward.

At this time, the embodiment of Fig. 112 to 118 is the spring when the

panel housing

20, 40 is expanded to the same height (Fig. 115) when the spring is in an expanded or compressed state, the panel housing is overlapped (Fig. 112) The spring is in a restored state. On the other hand, FIGS. 122 and 123 show the spring in the expanded or compressed state when the panel housing overlaps, and the spring in the restored state when the panel housing is unfolded.

Accordingly, in the embodiment of FIG. 112 to 118, when the

panel housing

20 and 40 are unfolded at the same height, the locking means or the coupling means (described in FIG. 121) is required to maintain the state. However, FIG. 122 and FIG. 123 need to have a locking means or a coupling means (described in FIG. 121) when the two panel housings overlap to maintain the state.

Of course, the compression inflation or restoring state of the spring may be reversed, resulting in a restoring state of the spring when FIGS. 112 and 118 are in the extended state in the embodiment. That is, when the locking means or the coupling means is in a compressed or expanded state, the upper and lower panel housings may be provided at positions where they are in contact with each other to serve as a locking function.

The action of the engaging means or the securing means can be seen by the movement of the two panel housings in FIG. That is, when the two panel housings touch each other, a little wider space is brought into contact with each other.
