DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The present invention is a foldable portable display device having an effect that one screen can be viewed by interconnecting at least two or more flat panel displays. In addition, since an input device for inputting information is provided on the same plane as the display, two or more input devices can be used.

As the flat panel display panel used in the present invention, all flat panel display types such as LCD, OLED, FED, PDP, and Electric Paper can be used. Then, detailed embodiments will be described according to the embodiments of the present invention.

- Example 1 -

1 and 2 are views showing a foldable portable display device of the present invention.

As shown in FIG. 1 , the foldable portable display device of the present invention includes two displays 2 and 4 and two panel housings 20 and 40 on which the displays are mounted. In addition, circuits or components for driving or mounting the display are provided in the panel housings 20 and 40 .

In addition, the two panel housings 20 and 40 are connected by a connecting shaft 6 that can be folded and unfolded, and a hinge is used as the connecting shaft 6 in this embodiment. However, a means for enabling folding and unfolding does not necessarily mean only using a hinge.

In other words, even if it is not in the form of a hinge or a shaft, it can be said that both panel housings can be connected to each other in such a way that they can be pushed and unfolded.

2 is a view of the foldable portable display device of the present invention in a folded state.

A cover means 85 is provided on the side surfaces of the panel housings 20 and 40 . The cover means 85 is positioned behind the display when the displays 2 and 4 are unfolded, but covers the side surface of the display when the displays 2 and 4 are folded. In the case of the cover means 85, a side cover 85a for blocking the side is further provided.

In order to make the distance between the displays 2 and 4 close, the panel housings 20 and 40 sidewalls or protective plates that protect the display side at the joint where the displays 2 and 4 are connected are thinly formed. And, at this time, the cover means 85 will protect the displays 2 and 4 from physical impact.

3 to 9 are diagrams illustrating an input device and a display.

In particular, the method of the input device applicable to the present invention has been described with reference to FIGS. 3 to 5 .

3 is a diagram illustrating a positional relationship between an input device and a display. There is an OUT-Cell method in the form in which the input device 200 and the display 2 are spaced apart from each other at a certain distance as in (A) of FIG. There is also an on-cell method in the form in which the input device 200 is located. In addition, there is an in-cell method in which a micro sensor is inserted into a display device by a completely different method.

That is, the present invention is applied to all input devices for inputting information on the display (2) (4).

4 is an embodiment showing a method of a sensor inserted into a display. The figure is a view showing one pixel in the display 2, and the pixel is provided with three pixels of R (Red), G (Green), and B (Blue). In addition, a thin film transistor (TFT) element is also provided in the area of a portion of the pixel, and a sensor is provided together with the element.

4A is a diagram of an embodiment in which the micro optical sensor 207 is built-in. The rectangle shown in (A) shows that there are three pixels in one pixel. That is, the TFT element and the micro photosensor 207 are provided in the pixel.

In addition, the sensor X-Line (207b) and the sensor Y-Line (207c) are connected to the optical sensor 207, respectively, so that the coordinate position value can be known.

Figure 4 (B) is a diagram showing an embodiment of the micro switch (Micro switch) (207a) type sensor is built-in. When the portion displaying the screen in the display 2, 4 is referred to as a display panel, the panel is composed of two substrates, and when pressure is applied to the outside of the substrate, the microswitch 207a of the portion to which the pressure is applied is the sensing principle. Similarly, the sensor X-Line 207b and the sensor Y-Line 207c are connected to the micro switch 207a, respectively, so that the position can be known.

And, if it is a sensor that can be inserted into a display pixel other than the above two methods, it is natural that the principle of the present invention is applied.

5 is a schematic cross-sectional view of an input device. FIG. 5A is a diagram illustrating a capacitive method, and FIG. 5B is a diagram illustrating a resistive film method.

That is, in FIG. (A), an electrode plate 241 is provided under the protective plate 240, and the electrode plate 241 is composed of one or two films coated with a transparent electrode. And, when a hand or a pin through which an electric current can pass is brought into contact with the upper portion of the protective plate 240 , the position of the contacted portion is sensed.

In addition, in FIG. (B), two films 241a and 241b coated with a transparent electrode on the upper portion of the protective plate 240 are provided to face each other while maintaining a constant distance, and the films 241a and 241b are disposed on top of the film 241a and 241b. When pressure is applied, the position of the part to which the pressure is applied is sensed.

In addition, an external protective plate (or decorative plate) 240a may be further provided on the upper end of the input device. And a desired pattern of coating is made on the protection plate 240a.

6 is a view illustrating a cross-section of a display, and has a shape in which pixel electrodes are located closer to each other at a seam. Since the pixel electrode constitutes an active area on which a screen is displayed, it means that the active area is located closer to the seam as a result.

LCD can be used as the display, OLED or electronic paper can be used, and whatever flat panel display is used, the distance between the display boundary 2g and the nearest pixel 2n at the seam 8 is very important. , it is natural that 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 shown.

The displays 2 and 4 include an insulating layer 53 , an electrode 54 , a coating electrode 58 , an organic multilayer film 53 , etc. on a substrate 51 , and a moisture absorption layer with a separator 57 interposed therebetween. (56) may be further provided.

Then, the substrate 51 is covered with the cover substrate 52 . At this time, the partition wall 2f seals the edge of the display. In addition, a driving unit 2k was provided on the opposite side of the joint.

On the other hand, when the display 2 is mounted on the chassis 16, at the seam, the chassis 16 covers only the side of the display or, even if the upper part is covered, only the portion P corresponding to the non-display area of the screen should be covered. .(marked in drawing)

In addition, the design structure of such a seam is not applied only to the OLED method, and it can be said that all flat-panel display devices are applied.

7 is an enlarged view of a seam portion of the display. In the present invention, since the seam is minimized by connecting two screens, a design to reduce the seam (non-display area of the screen) is required in the displays 2 and 4 as well.

As shown in the drawing, when there is a pixel 2n closest to the seam 8, the distance J between the adjacent pixel 2n and the barrier rib 2f is within 1 mm, and there is no problem even if the J value is 0.

In addition, the thickness (K) of the partition wall (2f) is also made less than 1 mm, at least 0.01 mm or more. Accordingly, the distance from the pixel 2n closest to the seam to the edge boundary 2g of the display 2 (4) is set to within 2 mm.

Here, the partition wall 2f refers to the boundary between the inside and the outside at the edge of the display.

Meanwhile, the displays 2 and 4 are usually mounted on a chassis 16, and the chassis is made of a metal material such as aluminum or alloy. Then, a display, a display driving unit, or a backlight component (when the display is an LCD) is mounted on the chassis to constitute a display module.

In this case, the chassis is not necessarily made of a metal material, and may be in the form of an appliance made of plastic resin. In addition, a mixed form of a metal material and a plastic apparatus is possible.

In addition, the thickness of the chassis 16 at the seam 8 is 0.01 mm or more and 1 mm or less. However, the maximum thickness of the most efficient chassis 16 should not exceed 0.5 mm. In addition, an open structure is also possible in the joint part.

Of course, it is not necessary that the boundary between the display boundary line 2g and the partition wall 2f completely coincide with each other at the seam 8, and the partition wall 2f may be provided within a range of 0.5 mm from the boundary line 2g. do.

8 is an enlarged view of a seam portion of the input device in the form of a capacitive type. It is a diagram showing the active area at the seam, when the area in which the input device can detect the presence or absence of contact is referred to as the active area.

As shown in the drawing, the distance from the active area boundary 223a to the input device boundary 250g is within 1 mm - 2 mm or 3 mm.

9 is an enlarged view of a seam in the resistive film method of the input device. That is, it has a structure in which two substrates (transparent plastics) coated with transparent electrodes are coupled to each other.

The distance M between the bus 250n and the barrier rib in the joint 8 is set to within 1 mm, and the thickness L of the barrier rib 250f is also set to within 0.01 mm to 1 mm. Of course, it is natural that the interval M may be 0 mm.

Here, the barrier ribs are used for the conductive films 220 to be coupled to each other or another plate to be coupled to the input device.

In addition, in the joint portion 8, the distance between the electrode wire 250n and the boundary 250g of the input device 200 is within 2 mm. Alternatively, the distance from the boundary of the active area 250a to the boundary 250g of the input device 200 is within 2 mm (or 3 mm).

Of course, it is not necessary that the boundary 250g of the seam 8 and the boundary of the partition 250f completely coincide, and it is natural that the partition 250f may be provided within 0.5 mm of the boundary 250g. .

In addition to the above two input devices (capacitive type and resistive type), it can be said that the principle of the present invention is applied to an input device capable of inputting information from a flat panel.

10 and 11 are diagrams of an embodiment showing a cross-sectional structure in which a display is mounted on a panel housing.

In FIG. 10, when the panel housings 20 and 40 are unfolded to be in close contact with each other, the displays 2 and 4 are adjacent to each other. At this time, the display (2) (4) is to be provided on the upper side of the panel housing (20, 40).

In addition, various circuits and devices 25 and 45 are provided inside the panel housings 20 and 40, and support portions 26 and 46 for supporting the displays 2 and 4 are also provided. In addition, a cover 24 is provided on the edges of the displays 2 and 4 . Meanwhile, the cover means 85 is omitted for convenience. In addition, the extension of the center of rotation A meets the surface of the cover (24). That is, the height of the rotation center is the height of the cover.

And, when the displays 2 and 4 are in close contact with each other, they may come into contact with each other, but in some cases, the distance between the displays may be 0.005 to 0.2 mm apart. If the gap is small, a thin protective film that seals and protects the side of the display is used.

11 is a view of an embodiment having a protective means on the top of the display. As shown in the drawing, a step 24a is provided on the side surfaces of the cover 24 and the panel housings 20 and 40, and the protection means 14 is mounted on the step 24a, so that the side surfaces of the displays 2 and 4 are Protective means 14 can be mounted on the front of the display (2) (4).

And the optical means 27 may be provided under the protection means 14 . At this time, the optical means is a means used to optically reduce the seam that is the interface between the displays 2 and 4 . And, the protection means 14 is formed as thin as 1 mm or 0.5 mm or less.

In this case, the optical means in the present invention may be referred to as an optical plate having a function of reducing the non-display area of the screen occurring at the boundary between the two displays. And as the optical means, a lens that refracts light, a micro lens, a micro prism, etc. can be used. In addition, various means for moving the path of the light toward the display boundary may be used.

That is, in the case of an in-cell type input device, the mutual distance between the micro-sensors in the seam 8 may be limited. When information is input as a contact or a point on the display (2) (4) and the area of a portion for sensing the input information is referred to as a sensing area, the portion provided in the first display is the first sensing area and the second sensing area. If the portion provided in the display is referred to as the second sensing area, the distance between the first sensing area and the second sensing area in the joint 8 of the displays 2 and 4 may be equal to the non-display area of the screen.

- Example 2 -

12 to 15 are block diagrams and flowcharts of a portable display device including an input device and a display.

In the present invention, two displays 2 and 4 are provided and two input devices 250-1 and 250-2 are also provided, and the input device is provided on the upper part of the display.

12 is a block diagram of the present invention, which is a block diagram illustrating control of a display and an input device.

In the drawing, the central processing unit 105 is a control means for controlling the overall operation of the portable display device of the present invention. The ROM 121 controls the execution program of the display device, the RAM 122 stores data generated when the program is executed, and the EEPROM 123 is the data required by the user and data required to process it. keep the

The R/F unit 124 as a radio frequency (Radio Frequency) tunes to an RF channel, amplifies an input audio signal, and converts an RF signal received from the antenna into an intermediate frequency signal. The input unit 110 is shown including various input devices, numeric keys, menu keys, and selection keys.

There is a display driving circuit 130a for driving the display by the output of the central processing unit 105, and there are first and second displays 2 and 4 for displaying information on the screen according to the output signal of the driving circuit.

In addition, by providing a gravity sensor 235, it is determined whether the two displays 2 and 4 are positioned vertically or horizontally. Of course, as a sensor for reflecting the position of the portable display device to screen control, it is natural that sensors commonly used in mobile phones, such as an acceleration sensor, a position sensor, and a gyroscope, can also be applied to the present invention.

In addition, the central processing unit controls the first and second input devices 250-1 and 250-2 through the first and second input device controllers 1401-1 and 140-2. That is, since there are two input devices 250-1 and 250-2, respectively, there are also two input device controllers 1401-1 and 140-2 to control corresponding input devices.

In this case, when an in-cell micro sensor is built in a display pixel, a sensor controller is provided instead of an input device controller. The sensor controller supplies a current to the micro-sensor and senses a signal of the micro-sensor.

In addition, the X-axis and Y-axis are connected in the form of a matrix with all micro-sensors, so that the position coordinate values of the detected sensors can be known.

That is, the first and second sensors may be referred to instead of the first and second input devices in the above description. Accordingly, the first and second sensors refer to micro-sensors inserted into display pixels. Accordingly, the set of micro-sensors inserted into the first display 2 may be referred to as a first sensor, and the set of micro-sensors inserted into the second display 4 may be referred to as a second sensor.

At this time, the input devices 250-1 and 250-2 shown in the block diagram of this figure are the same as the input devices 200 and 400 shown in other drawings of the present invention.

13 to 14 show an embodiment of a block diagram of the present invention.

13 , in the central processing unit or main body control unit 105 , a control unit 110 , a memory 120 and a time controller 125 , a display driving unit 130 and an input device driving unit 140 are included. is provided

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 is provided in the main body controller 105 to form one component. can be manufactured with

In addition, the display driver 130 divides the screen and transmits 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 screens of the displays 2 and 4, source 2b and 4b for providing data signals and gates 2c and 4c for providing line selection signals. will exist

Of course, even at this time, the data line of the first display 2 and the data line of the second display are not necessarily divided 1:1. It goes without saying that it can be divided into various ratios such as 2:3, 10:6, 6:4, etc. That is, the capacity of the first display 2 and the second display 4 does not necessarily have to be 1:1 according to the design of the terminal.

14 is a diagram illustrating the input device driving unit 140 in detail.

First, the calibration function performing unit 141 performs a calibration function on the input device 250 when the system is first operated. A panel signal corresponding to an accurate coordinate value of the input device 250 is selected according to the calibration function performed by the calibration function performing unit 141 .

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

In addition, the average number of detections adjustment unit 143 adjusts the average number of detections of the panel signal output from the input device 250 based on screen resolution information of the display device 2 and 4 provided from the controller 110 . When the screen resolution is changed to a high resolution, the number of times of detection of the average value is adjusted to be greater than a previously set value. Conversely, when the screen resolution is changed to a low resolution, the number of times of detection of the average value is adjusted to be smaller than a previously set value.

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

The adjusted panel signal generator 144 uses the changed screen resolution of the display devices 2 and 4 provided from the controller 110 or the location information of the display screen changed by virtual scrolling and the average value of 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 driving unit 140 controls the signal for the first input device 250-1 and Signal control of the second input device 250-2 is performed.

However, in the switching device 145 under the control of the time controller 125 and the controller 110 , the first input device 250-1 and the second input device 250-2 alternately operate the input device driver 140 . It can also be connected to

The signal generated by the first input device 250-1 is processed and then the signal generated from the second input device is processed, and each input device 250-1 alternately divides a very short time into a circuit. It is to process the signal of (250-2).

As in this figure, when the switching element 145 is used, an embodiment is shown in which two or more input devices can be driven by using one driving unit. However, the switching element 145 may not be used and in that case It goes without saying that as many input device drivers as the number of input devices can be provided.

15 is a view showing a flowchart of the present invention.

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

The control unit 110 in the main body control unit 105 divides the screen display data stored in the memory 120 or the received screen display data. The controller 125 performs this.

Accordingly, the main body controller 105 divides the screen and transmits screen data information corresponding to the first display and the second display, respectively. (Step 402)

Then, the input device driver 140 drives the first input device 250 - 1 by the switching device 145 . That is, the information output from the first input device is controlled (step 404). Then, the information output from the first input device is controlled to match the information displayed on the screen of the first display 2 (step 406).

Similarly, the input device driver controls the output signal from the second input device by the switching device 145 (step 408), and controls the signal of the second input device according to the screen display information of the second display (410). step)

And, if there is no stop command, the main body controller continuously divides the screen and drives each input device. However, if there is a stop command, this series of execution functions ends. (Steps 412 and 414)

As a result, the first display and the second display divide one entire screen vertically or horizontally, and the first display and the second display have a structure adjacent to each other, A first input device and a second input device corresponding to the output information of the second display are provided, and since the input devices are also adjacent to each other, the two input devices are used as one input device.

- Example 3 -

16 to 27 are views showing a structure in which a display, an input device, or a light means is mounted.

16 is an exemplary embodiment in which the display and the input device are separated by the same distance.

As shown in the figure, when forming the part marked with "V" in the form of a protective film, the protective film should be as thin and strong as possible. can be used

When the part marked with "V" is a protective film or protective means, it is preferable to set the thickness to about 0.005 mm or more and 0.5 mm or less. In this case, the sealing effect may be more important than protection from physical impact. The minimum distance between the two displays 2 and 4 is 0.01 mm, and the maximum is 1 mm. Similarly, the distance between the two input devices 200 and 400 is at least 0.01 mm and the maximum is 1 mm.

And, when "V" is in the form of a protection means, the thickness can be within 1.5 mm.

On the other hand, the portion marked "V" can be formed integrally with the panel housing without using a separate protective means. In this case, the sidewalls of the panel housings 20 and 40 protect the sides of the display 20 and 40 and the side surfaces of the input devices 200 and 400 .

In this case, the portion marked with “V” is shown to be thinner than the panel housing sidewalls 20 and 40, in order to make the distance between the displays as close as possible. That is, if it is made thinner than the side wall of the panel housing, it is suitable to be within 0.5mm, but it may be within 1mm at most.

That is, the “V” portion may be thicker than other sidewalls of the panel housings 20 and 40 .

Alternatively, even if the panel housings 20 and 40 are thicker than the sidewalls, it is preferable not to exceed 2 mm. In conclusion, the distance between the displays 2 and 4 may be a minimum of 0.1 mm and a maximum of 4 mm.

And, even if the thickness of "V" is only 0.5 mm, the distance between the displays 2 and 4 can be 4 mm. In addition, when the "V" is separated from the side of the display or the input device, there may be a space therebetween, but a shock absorbing member may be provided.

Naturally, the distance between the joint portion 8 and the input devices 200 and 400 is also a minimum of 0.01mm and a maximum of 4mm.

17 is an embodiment in which a distance between input devices is shorter than a distance between displays.

As shown in the figure, the display (2) (4) and the input device 200 are provided so as to have a mutually symmetrical structure around the seam (8). Here, a flexible printed circuit (FPC) (2c) (4c) (250c) for connecting the display device and the input device to the connectors (2d) (4d) (250d) is provided, and in this case, the FPC (2c) (4c) is provided. ) (250c) is mounted on the opposite side of the seam.

Of course, there are cases in which the displays 2 and 4 and the input device 200 are separated by a predetermined interval and mounted on the panel housings 20 and 40 separately from each other. (Out-cell method) In this case, when connecting the external signal line FPC to the input device 200 , one side may be selected from among the other three sides except for the seam 8 .

29 is a view showing the structure of one electrode of the display panel.

The display is usually divided into a driving part panel part, and the display panel is usually made of a glass substrate, and in some cases it is also made of a transparent plastic substrate.

In this case, the drawing is a view showing a display panel. When each of the four sides is 1, 2, 3, and 4 sides, respectively, if the first side is a joint portion, the driving driver 2k is mounted on the third side opposite to that.

Then, the supply line 2i connected to the panel electrode 2f from the second side and the fourth side is connected to the third side. In this way, it is possible to send a signal to the entire display panel with only the driving driver 2k mounted on the third side.

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

Of course, when the displays 2 and 4 and the input devices 200 and 400 are mounted at a predetermined distance apart, the input device connector can be mounted on three sides except for the seam.

33 is a view showing a state in which the display 2 is mounted on the chassis 16, and connectors and signal lines are omitted for convenience. As shown in the drawing, the active area is located close to the seam, and even when the chassis 16 covers the edge of the upper portion of the display panel 2a, the area other than the seam is covered thicker.

Meanwhile, the fixing part 16c is provided on the chassis 16 to be firmly fixed to the panel housing 20 .

In this embodiment, the driving driver is provided on one side of the display, and in many cases, the driving driver is installed on two sides according to the size of the display. In that case, it is enough to select two of the other three sides except for the seam and provide a driving driver.

44 to 48 are diagrams of an embodiment showing an input method.

44 and 45 are diagrams showing an embodiment of inputting information on the surface of the display 2 and 4 in the display device of the present invention. FIG. 44 is a form of inputting information in one screen mode, and FIG. 45 is a form of inputting information in two screen modes.

Here, when inputting information through the input device, the single screen mode is a mode in which two screens are used as one screen, and the two screen mode is a mode in which two screens are separated and information is inputted.

Fig. 44 (A) is a diagram of an embodiment showing that two or more input points 147 are also recognized, and a path 147a (indicated by an arrow) along which the points 147 moves is also recognized. In this case, even if two dots 147 exist across two screens, it is recognized as if they exist on one screen.

If the screen is reduced when two dots move inward by a predetermined program and the screen is enlarged when two dots move outward, the central processing unit 105 or the control unit 110 controls the movement of the two dots 147 In response, screen information on which the screen is enlarged or reduced is sent to the display driving units 130a and 130 to display the screen. That is, two screens are combined into one screen to enlarge or reduce.

44(B) is an embodiment showing when two or more points 147 select a pattern (or image) 147b. Even when the pattern (or image) 147b spans two screens, it is recognized as if it were on one screen.

Here, the point is a point indicating a position for inputting information when inputting information on the display (2) (4) screen.

If two points selected for a pattern or image by a predetermined program move inward, the pattern (or image) is reduced, and when the pattern (or image) is enlarged when moved outward, the central processing unit 105 or the control unit 110 ) transmits screen information on which the pattern (or image) is enlarged or reduced according to the movement of the two points 147 to the display drivers 130a and 130 to display the enlarged or reduced screen.

44(C) shows that one point 147 selects a pattern (or image) 147b, and when the point moves, the pattern (or image) 147b also moves along the point 147 movement path. .

If the above movement is programmed as a map, the central processing unit 105 or the control unit 110 moves the pattern (or image) 147b by moving the point, and the pattern (or image) 147b This means that the movement is made as if it were moving on a single screen.

In (C), a case where the point 147 moves left and right and a case of rotation are shown, and the selected pattern (or image) 147b may be rotated during rotation.

44(D) is an embodiment showing that one point 147 moves. Even if the moving path 147a passes through two screens, it is as if it moves within one screen.

If the screen is programmed to change according to the movement path of the dot, the central processing unit 105 or the control unit 110 sends information about the previous screen or the next screen to the display driver 130 (130a) by the movement of the dot. can cause the screen to be displayed.

Similarly, when the movement path 147a of the point 147 rotates, the gray surface may also be rotated.

45 is a diagram of an embodiment showing an input form of information in a two-screen mode.

45A shows that when the point 147 is moved within one screen, the screen is displayed according to the movement path 147a. In this case, the result is displayed only within one screen.

45(B) shows that one pattern (or image) 147b is selected within one screen. And, according to the movement path 147a of the point 147, the pattern (or image) 147b may move in one screen or move to another screen.

46 is a view of limiting the height of the protection means 14 (or sidewalls or extensions) existing between the two input devices 200 and 400 (or two protection plates may be provided).

In the present invention, a protection means 14 (or a side wall or an extension) is provided between the two input devices 200 and 400 or the protection plate.

In addition, instead of the protection means 14, the panel housings 10 and 40 sidewalls may be provided, and the cover sidewall 24d or the sidewall extension 24a extending from the cover frame (or frame) may be provided. .

In addition, in order to reduce the inconvenience of movement between the two touch panels, it is preferable to limit the value of H1 to H2 within 2 mm or 3 mm. Of course, the more the values of H2 and H3 are 0 or close to 0, the more convenient it is to use.

47 is a view showing a flowchart of information input through the input device of the present invention.

When the display device of the present invention is started (step 300), the first and second displays are driven and the first and second input devices (or sensors) are also controlled (step 305).

In the above, the first and second sensors refer to micro-sensors inserted into the display pixels, and a set of micro-sensors inserted into the first display 2 is the first sensor and the micro-sensors inserted into the second display 4 . A set of can be referred to as a second sensor.

At this time, to control the input device is to send a current to the input device and to detect the coordinates at which information is input when information is input to the input device. This sensing is performed through the input device driving unit 140 and the central processing unit 105 .

Select whether it is one-screen mode or two-screen mode. (Step 310)

In the one screen mode, the first and second displays are driven as one display, and the first and second input devices (or sensors) are also controlled as one input device.

That is, even if the movement path 147a of the input point 147 passes through the first and second input devices 200 and 400, it is controlled as if it passed through one input device.

As a result, the first and second displays are combined into one screen, and a position corresponding to the coordinate value of one combined screen is compared with the coordinate value input through the input device (sensor), and the central processing unit or the control unit displays the display To run the program to display in

That is, when the input coordinate value is one point, when there are two or more points, or when the input coordinate value moves, the corresponding program is executed.

In the single screen mode, it is determined whether the coordinate value input through the input device (or sensor) selects the coordinate value of the pattern (or image) displayed on the display (Step 315).

If a pattern (or image) is not selected, even if the input point and the movement path of the input point are both in the first and second input devices (or sensors), the program runs as if information was input through one input device and the screen moves. (Step 320) At this time, as in the case where a pattern is not selected in the single screen mode as described in the previous embodiment, the central processing unit or the control unit executes a predetermined program.

In addition, if a pattern (or image) is selected, even if the input point and the movement path of the input point are both in the first and second input devices (or sensors), the selected pattern (or image) is The moving program is executed. (Step 325)

At this time, when a pattern is selected in the single screen mode as in the previous embodiment, the central processing unit or the control unit executes a predetermined program according to the number of dots or the movement path of the dots.

Then, when the two screen mode is selected in step 310, a program determined according to whether a pattern (or image) is selected in the two screen mode, the number of input dots, and a movement path is executed (step 330).

That is, as in the embodiment of the previous figure, the program is executed according to the number of input points and the movement path of the points in the two screen mode.

In addition, in the single screen mode, the central processing unit or the control unit sends a driving signal to the display driver according to the program control result, and displays the result on the first and second displays, which is displayed as a single screen (Step 335).

On the other hand, even if the program is executed using the first and second displays as separate screens, the program determined according to the input points and the movement path of the points is executed, and the results are displayed on the first and second displays. ( 340 steps)

Finally, after the program execution result is displayed on the screen, if there is no stop command, it moves to the initial step of step 305, and if there is a stop command (step 345), the program ends. (step 355)

48 is a view for explaining the principle of making two devices as one.

As shown in the drawing, each of the first and second input devices or the first and second displays has corresponding coordinates. In fact, in the present invention, since the input devices or displays are separated from each other, the corresponding coordinates are separated as shown in FIG. (A).

However, to control two input devices as if they were one input device means to connect the coordinates that are actually separated as shown in Figure (B).

On the other hand, the shaft having a certain thickness for the shaft rigidity can provide more reliability, so the diameter (B) of the shaft is 0.25 times or more of the thickest part (A) of the panel housings 20 and 40 it's good That is, if the value of "B" is 0.25 times or more of the value of "A", it brings stability by design. Of course, it is good that the value of "B" is not greater than the value of "A".

On the other hand, the moving cam 69 is coupled to one part of the shafts 61 and 62, but linear motion in the direction of the shaft center is possible.

Accordingly, when the shafts 61 and 62 are rotated, the protrusions 68a and 69a of the fixed cap and the moving cam meet or cross each other. When the protrusions 68a and 69a meet, pressure is applied to the spring, and when the protrusions cross each other, the pressure of the spring is released.

69 is a view showing an angle;

From 0 degrees to α degrees, the protrusions 68a and 69a are in a state of crossing each other, and similarly from β to 180 degrees, the projections 68a and 69a are in a state in which they are staggered. However, from α to 180-β degrees, the protrusions 68a and 69a meet each other and pressure is applied to the spring.

Therefore, when the panel housings 20 and 40 are opened, a force is added after a certain angle α, and the panel housings open by themselves after 180-β.

In this case, the angle of α or β should be within 50 degrees, but it is appropriate. Depending on the design needs, it can be enlarged up to 80 degrees. And, the angle value is determined by the angle of the area occupied by the protrusion in the entire cam.
