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

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

- Example 1 -

1 and 2 are views showing a foldable portable display device according to 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 in which the displays are mounted. In addition, the panel housings 20 and 40 are provided with circuits or components for driving or mounting the display.

And, the two panel housings 20 and 40 are connected by a connecting shaft 6 capable of folding and unfolding, and a hinge is used as the connecting shaft 6 in this embodiment. However, if it is a means for enabling folding and unfolding, it does not necessarily mean that only a hinge is used.

That is, even if the two panel housings can be connected to each other in such a way that they are not hinged or shafted, it can be said that they are all applicable.

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

Side surfaces of the panel housings 20 and 40 are provided with cover means 85. The cover means 85 is located on the back side of the display when the displays 2 and 4 are unfolded, but covers the side 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 shorten the distance between the displays 2 and 4, the side walls of the panel housings 20 and 40 or protective plates protecting the side surfaces of the displays are thinly formed at the seams where the displays 2 and 4 are connected. And, at this time, the cover means 85 protects the displays 2 and 4 from physical impact.

3 to 9 are views showing an input device and a display.

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

3 is a diagram illustrating a positional relationship between an input device and a display. As shown in (A) of FIG. 3, there is an OUT-Cell method in which the input device 200 and the display 2 are spaced apart at regular intervals, and as shown in (B), the display 2 is directly on top. There is also an on-cell method in which the input device 200 is located. In addition, there is also an in-cell method, which is a form of inserting a micro sensor into a display device in a completely different way.

That is, the present invention applies to all input devices that input information on the displays (2) and (4).

4 is an embodiment showing a method of a sensor inserted into a display. The figure shows one pixel in the display 2, and the pixel includes 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 one part of the pixel, and a sensor is provided together with the element.

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

4(B) is a view showing an embodiment in which a sensor of the micro switch 207a type is embedded. When the part displaying the screen in the normal display (2) (4) is called a display panel, the panel is composed of two substrates, and when pressure is applied to the outside of the substrate, the micro switch 207a of the part where pressure is applied is the principle that is detected. Similarly, the sensor X-Line (207b) and the sensor Y-Line (207c) are connected to the micro switch (207a), respectively, so that the location can be known.

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

FIG. 5 is a simplified cross-sectional view of an input device. FIG. 5(A) is a view showing a capacitive type, and FIG. 5(B) is a view showing a resistive type.

That is, in (A), the electrode plate 241 is provided under the protective plate 240, and the electrode plate 241 is composed of one or two sheets of film coated with a transparent electrode. In addition, when a hand or a pin through which current can flow is brought into contact with the top of the protective plate 240, the position of the contacted portion is sensed.

In addition, in (B), two films 241a and 241b coated with transparent electrodes are provided on top of the protective plate 240 to face each other while maintaining a regular interval, and on top of the films 241a and 241b. When pressure is applied, the position of the part to which pressure is applied is sensed.

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

6 is a cross-sectional view of a display, and has a shape in which pixel electrodes are positioned closer to each other in a seam portion. Since the pixel electrode constitutes an active area where a screen is displayed, as a result, the active area is located closer to the seam.

LCD can be used as a display, OLED or electronic paper can also be used, and whatever flat panel display is used, the distance between the display boundary 2g and the nearest pixel 2n is very important in the joint 8, , it is natural that the design value designed in the present invention can be applied to all flat panel displays as it is.

An OLED method was used in the portable display device of the present invention, 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, and the like on a substrate 51, and a moisture absorption layer with a separator 57 therebetween. (56) may also be provided.

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

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

And, it can be said that the design structure of the joint part is not applied only to the OLED method, and is applied to all display devices in the form of a flat panel.

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 (screen non-display area) must be made in the display (2) (4).

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

In addition, the thickness K of the partition 2f is also within 1 mm, and at least 0.01 mm or more. Therefore, the distance from the pixel 2n closest to the seam to the edge boundary 2g of the display 2, 4 is set within 2 mm.

Here, the barrier rib 2f means a 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 an alloy. And, a display module is formed by mounting a display and a display driver or a backlight component (when the display is an LCD) to the chassis.

At this time, the chassis does not necessarily have to be made of a metal material, and may be in the form of an instrument made of plastic resin. In addition, a mixed form of metal material and plastic mechanism is also possible.

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

Of course, it is not necessary that the boundary between the display boundary 2g and the partition wall 2f completely coincide at the joint 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 of the input device in the form of a capacitive type. This is a diagram showing the active area at the seam when the area where the input device can sense whether or not it is touched is referred to as an 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 a resistive type input device. That is, it has a structure in which two substrates (transparent plastic) coated with transparent electrodes are coupled to each other.

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

Here, the barrier rib is used to couple the conductor films 220 to each other or to couple other plates in the input device.

In addition, in the joint portion 8, the distance between the electrode line 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, the boundary 250g of the joint 8 and the boundary of the partition wall 250f do not need to completely coincide, and it is natural that the partition wall 250f may be provided within a range of 0.5 mm from 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 on 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.

10 shows that when the panel housings 20 and 40 are unfolded and brought into close contact with each other, the displays 2 and 4 are brought into close contact with each other. At this time, the display (2) (4) is provided at the top of the side surface of the panel housing (20) (40).

In addition, various circuits and devices 25 and 45 are provided inside the panel housing 20 and 40, and support portions 26 and 46 supporting the displays 2 and 4 are also provided. Also, a cover 24 is provided at the edge of the display 2 or 4. Meanwhile, the cover means 85 is omitted for convenience. In addition, the extension line of the rotation center A meets the surface of the lid 24. That is, the height of the center of rotation is the height of the lid.

In addition, 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 gap 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.

Figure 11 is a view of an embodiment having a protective means on top of the display. As shown in the drawing, by providing a step 24a on the side of the cover 24 and the panel housing 20, 40, and mounting the protective means 14 on the step 24a, the side of the display 2, 4 A protective means 14 may be mounted on the front of the display 2 or 4.

And an 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, which is the interface between the displays 2 and 4. And, the protective means 14 is formed thinly less than 1 mm or 0.5 mm.

At this time, the optical means in the present invention can be referred to as an optical plate that functions to reduce a screen non-display area generated at the boundary between the two displays. And, as the optical means, a lens that refracts light, a micro lens, a micro prism, and the like can be used. In addition, various means for moving the light path toward the display boundary can be used.

That is, in the case of an in-cell type input device, the mutual distance between the microsensors at the seam 8 may be limited. When information is input by contact or point on the display (2) (4) and the area of the part that detects the input information is called the sensing area, the part provided in the first display is the first sensing area second 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 at the joint 8 of the display 2 and 4 may be equal to the screen non-display area.

- Example 2 -

12 to 15 show block diagrams and flow charts 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, so that the input device is provided on top of the display.

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

In the figure, the central processing unit 105 is a control means for controlling the entire 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 EPROM 123 stores the data required by the user and the data required to process it. keep

The R/F unit 124 is a radio frequency, and tunes to an RF channel, amplifies an input voice signal, and changes an RF signal received from an antenna into an intermediate frequency signal. The input unit 110 includes various input devices, number keys, menu keys, and selection keys.

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

In addition, a gravity sensor 235 is provided to determine whether the two displays 2 and 4 are positioned vertically or horizontally. Of course, as a sensor for reflecting the position of a portable display device to screen control, it is natural that sensors commonly used in mobile phones such as acceleration sensors, position sensors, and gyroscopes 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 the respective input devices.

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

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

That is, it may be referred to as the first and second sensors instead of the first and second input devices. Therefore, the first and second sensors refer to micro-sensors inserted into display pixels. Accordingly, a set of microsensors inserted into the first display 2 may be referred to as a first sensor, and a set of microsensors 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 drawing are the same as the input devices 200 and 400 shown in other drawings of the present invention.

13-14 show block diagram embodiments of the present invention.

As shown in FIG. 13, in the central processing unit or main body controller 105, a controller 110, a memory 120, a time controller 125, a display driver 130, and an input device driver 140 is provided

That is, each element that functions as the controller 110, memory 120, time controller 125, display driver 130, and input device driver 140 is all provided in the main body controller 105 as one component. can be manufactured with

In addition, the display driving unit 130 splits the screen and sends data to the first display 2 and the second display 4 respectively. In addition, the input device driver 140 also calibrates 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), a source (2b) (4b) unit for providing a data signal and a gate unit (2c) (4c) for providing a line selection signal will come into existence

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

14 is a view showing the input device driving unit 140 in detail.

First of all, the calibration function execution unit 141 performs a calibration function for the input device 250 when the system initially operates. According to the calibration function performed by the calibration function execution unit 141, a panel signal corresponding to an accurate coordinate value for the input device 250 is selected.

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

Also, 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 devices 2 and 4 provided from the controller 110. When the screen resolution is changed to a high resolution, the number of detections of the average value is adjusted to be greater than a previously set value. Conversely, when the screen resolution is changed to a lower resolution, the average value detection count is adjusted to be smaller than a previously set value.

Also, the average value detection unit 142 detects the average value of the panel signal transmitted from the input device 250 based on the number of average detection times adjusted by the average 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 control unit 110 or the positional 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, and therefore, the input device driver 140 controls the signal for the first input device 250-1 and Signal control of the second input device 250-2 is performed.

However, under the control of the time controller 125 and the control unit 110, the switching element 145 alternately operates the first input device 250-1 and the second input device 250-2. can also be connected to.

The signal generated by the first input device 250-1 is processed, and then the signal generated by the second input device is processed. It is to process the signal of (250-2).

As in this drawing, when using the switching element 145, an embodiment in which two or more input devices can be driven using one driving unit has been shown. However, the switching element 145 may not be used, and in that case Of course, the number of input device driving units may be provided.

15 is a diagram showing a flow chart of the present invention.

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

The controller 110 in the main body controller 105 divides the screen display data stored in the memory 120 or the received screen display data. The controller 125 will perform.

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, by the switching element 145, the input device driver 140 drives the first input device 250-1. 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 according to the information displayed on the screen of the first display 2 (Step 406).

Likewise, the input device driving unit controls the output signal from the second input device by the switching element 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, but if there is a stop command, these series of functions are terminated. (Steps 412 and 414)

As a result, the first display and the second display display one entire screen by dividing it vertically or horizontally, the first display and the second display have a structure in which they are adjacent to each other, and corresponding to the output information of the first display The first input device and the second input device corresponding to the output information of the second display are provided, and the input devices are also adjacent to each other, so that 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 are mounted.

16 is an example of a case in which a display and an input device are separated by the same distance.

As shown in the figure, when the part marked with "V" is formed in the form of a protective film, since the protective film must be as thin and strong as possible, a metal film or resin film is used, or a material coated with a metal or inorganic film is used. can be used

When the portion marked with "V" is a protective film or protective means, the thickness is preferably set to 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 distance between the two displays (2) and (4) is at least 0.01mm and the maximum is 1mm. Similarly, the distance between the two input devices 200 and 400 is at least 0.01 mm and at the maximum is 1 mm.

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

Meanwhile, the portion marked with "V" may be integrally formed with the panel housing without using a separate protective means. In this case, the side wall of the panel housing 20 or 40 protects the side of the display 20 or 40 and the side of the input device 200 or 400.

At this time, the portion marked with “V” is shown thinner than the side walls 20 and 40 of the panel housing, and this is to make the distance between the displays as close as possible. That is, when thinning the side wall of the panel housing, within 0.5 mm is appropriate, but may be within 1 mm at the maximum.

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

Even if it is thicker than the side walls of the panel housings 20 and 40, it is better not to exceed 2 mm. In conclusion, the distance between the displays 2 and 4 can 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. And, when the display side or the input device side and "V" are apart, the space between them may be a space as it is, but a shock absorbing member may be provided.

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

17 illustrates an example in which the distance between input devices is smaller than the distance between displays.

If the board provided between the input devices 200 and 400 is referred to as "V1" and the board provided between the displays 2 and 4 is referred to as "V2", the distance of "V1" is greater than the distance of "V2". small. That is, the distance between the input devices 200 and 400 is shorter than the distance between the displays 2 and 4.

At this time, both "V1" and "V2" may be integrally formed with the sidewall of the joint of the panel housing 20, 40.

In addition, only "V2" is integrally formed with the sidewall of the joint of the panel housing (20, 40), and "V1" may be a separate protective film or protective means. In the case of using a protective film or protective means, the protective means or film described in the previous embodiment is followed as it is.

At this time, the distance between the displays 2 and 4 and the distance between the optical means 27 are equal to each other. As shown in the drawing, a protective film is provided to make the distance as close as possible. Naturally, the protective film is within 0.5 mm.

21 and 22 are diagrams of another embodiment showing the arrangement of a display and components.

It goes without saying that the thicknesses of the panel housings 20 and 40 may be different from each other as shown in the drawings. In the present invention, the panel housings 20 and 40 serve as a case in a portable display device.

Among the two displays 2 and 4, the bottom plate of the panel housing 20 is located directly under one display 2, and the main body control unit or central processing unit and battery are located under the other display 4. are provided

FIG. 22 is a view showing the distance (S) between the bottom part of the panel housing 20 and the display. The distance may be 0 due to complete close contact, but a space may be formed. Of course, since it cannot be made too thick, it is recommended that the interval (S) be within 0.5 mm or within 2.5 mm.

Further, although separate illustration is omitted in the drawing, it is natural that a shock absorbing plate in the form of a display support or a sheet for absorbing shock may be inserted into the gap S.

23 is a view of an embodiment in which the optical unit 27 is provided on top of the display 20 or 40 and the input device 200 or 400 is provided thereon.

The displays 2 and 4 have a screen non-display area such as a barrier rib (or sealant) or chassis 16, and the optical means 27 naturally exists in the screen non-display area to reduce seams.

At this time, "V5" attached to the side of the display 2 and 4, the optical means 27 and the input device 200 and 400 represents a protective film or a side wall of the panel housing.

In the case of a protective film, it may have a coating form. And, within tens of micrometers or 0.2 mm, it may have a sealing effect rather than physical impact, and also, within 0.5 mm or 1 mm, it may be in the form of a protective means.

In addition, “V5” may be integrally formed with the panel housings 20 and 40. In this case, it may be as thick as the panel housings 20 and 40, slightly thicker, or thinner.

24 is a diagram illustrating a case where the distance between displays is greater than the distance between the input devices and the optical means.

"V6" located on the side of the display (2) (4) may be integrally formed with the panel housing (20) (40), or "V6" may be a separate protective means. The thickness is smaller than that of the side walls of the panel housings 20 and 40, but may be the same or slightly larger.

In addition, the "V7" located on the side of the optical means 27 and the input device 200, 400 may be integrally formed with the panel housing 20, 40, but may also be formed in the form of a separate protective means. there is. However, the thickness is smaller than that of "V6".

-Example 4-

28 to 33 are diagrams illustrating the structure of a display module (Module).

28 is a diagram showing an actual arrangement of a display and an input device.

28 shows an on-cell method, and when the input devices 200 and 400 are provided directly on top of the displays 2 and 4, it is an embodiment in which the display and the input device come into close contact with each other. .

As shown in the drawing, the displays 2 and 4 and the input device 200 are provided so as to have a mutually symmetrical structure around the joint 8. Here, an FPC (Flexible Printed Circuit) (2c) (4c) (250c) connecting the display device and the input device to the connectors (2d) (4d) (250d) is provided. At this time, the FPC (2c) (4c) (4c) ) (250c) is mounted on the opposite side of the seam.

Of course, there are cases where the displays 2 and 4 and the input device 200 are separated at regular intervals and separately mounted in the panel housings 20 and 40. (Out-cell method) In this case, when connecting the external signal line (FPC) to the input device 200, one of the other three sides excluding the joint 8 may be selected and connected.

29 is a diagram illustrating a structure of one electrode of a display panel.

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

At this time, the drawing is a drawing showing the display panel. When each of the four sides is referred to as 1, 2, 3, and 4, respectively, and the first side is referred to as a joint, the driving driver 2k is mounted on the opposite third side.

Then, the supply line 2i connected to the panel electrode 2f at the second and fourth sides is connected to the third side. In this way, signals can be sent to the entire display panel only with the drive driver 2k mounted on the third side.

30 to 32 are views showing the shape of a display panel according to another embodiment.

30, when the first side is a seam, the portion where the driving driver 2c is located becomes the fourth side. That is, when the seam is set to the right (left side in some cases), the part where the driving driver 2k is located is up or down.

In order to mount the drive driver 2c on the fourth side, the supply line 2i connected to the panel electrode 2f of the first or third side is connected to the fourth side. That is, the supply line 2i is divided into one side and three sides so as to reach the fourth side. At this time, the supply line 2i is an electrical wire connected to the drive driver 2k to supply a signal line. In addition, although it is simply expressed as the electrode 2f in the present invention, it may actually mean a pixel electrode that sends a driving signal to a thin film transistor (TFT).

31 is a view of another embodiment in which the connection supply line is changed,

When the first side is referred to as a seam, the supply line 2i does not pass through the first side in order to minimize the seam. Then, the supply line 2i passes through the third side opposite to the joint 8, and the supply line 2i meets the drive driver 2k.

Of course, depending on the design conditions, the supply line 2i can be made to pass more on the three sides and less on the first side. That is, the passing rate of the supply line 2i can be distributed to the third side and the first side at a constant rate.

32 is a diagram when two displays are arranged.

The drawing shows an in-cell method in which the input devices 200 and 400 are mounted directly above the displays 2 and 4, and if the joint 8 is on the right side (left in some cases), the drive driver The FPC (2c) (4c) or the external connection connector (2d) (4d) connected to is located on the lower side (which may be on the upper side in some cases).

Likewise, the FPC 250c and the connector 250d for connecting the input device are also located on the lower side.

Of course, if the displays 2 and 4 and the input devices 200 and 400 are mounted at a certain interval, the input device connector can be mounted on three sides excluding 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 upper edge of the display panel 2a, the area other than the seam is covered more thickly.

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

This embodiment is an embodiment for providing a driving driver on one side of the display, and in many cases, driving drivers are installed on two sides depending on the size of the display. In this case, two of the other three sides excluding the seam need only be selected and equipped with a driving driver.

Meanwhile, instead of the cover sidewall 24d, it may simply be provided in the form of a protective film, or the cover sidewall 24d may be omitted so that the joint 8 of the frame 20b may have an open structure. Similarly, the cover sidewall 24d or the protective film may be provided at the joint of the cover frame 24 . Here, the cover sidewall 24d or the protective film serves to protect the joint 8 of the input device 200 or 400.

In addition, in the present invention, when the cover frame 24 or frame 20b is mounted on the panel housing 20, it is natural that it is mounted with grooves, protrusions, screws, etc., but this is a common Since it is based on the method, a special description is omitted and illustrated in the drawings.

39 is a structure made by combining the cover frame 24 and the frame 20b described above. The upper part and the lower part are provided in the form of a cover 24, and the side part is provided with mask printing (16d). In the drawing, a step is formed because the cover 24 and the input device 200 have a different height, but depending on the design, the height of the cover 24 and the input device 200 may be the same, so the step may not be formed. .

40 shows a structure in which a plate-shaped optical means 27 having a certain thickness can be placed on top of the input device 200. That is, it has a structure in which the optical means 27 can be placed on top of the input device 200 and can be removed as needed.

At this time, as shown in the drawing, when the frame 20b is formed somewhat high, it may be designed to have an optical means inside the frame and play a role in holding the optical means 27. To this end, the material of the part where the screen is not displayed at the bottom of the optical means can be made of a material that has a high friction coefficient and has a property of sticking well to glass or a plate.

41 and 42 are views of another embodiment of a cover frame or frame.

Figure 41 shows the cover frame (Frame) form of another embodiment. That is, as shown in the drawing, the side wall extension portion 24a is provided at the joint portion 8 of the cover frame 24. Accordingly, it is natural that the joint portion 8 has a structure in which the sidewall extension portion 24a can be in close contact with the side surface of the joint portion of the display 2 or 4 or the side surface of the joint portion of the input device 200 or 400.

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

44 and 45 are views of an embodiment showing a form of inputting information on the surface of the display (2) (4) in the display device of the present invention, FIG. 44 is a form of inputting information in one screen mode, and FIG. 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 information is input by separating the two screens.

44(A) is a diagram showing an embodiment in which two or more input points 147 are also recognized, and a path 147a (indicated by an arrow) along which the points 147 move is also recognized. At this time, even if the two dots 147 exist across two screens, they are recognized as existing on one screen.

If the screen is reduced by a predetermined program when the two dots move inward and the screen is enlarged when the two dots move outward, the central processing unit 105 or the controller 110 moves the two dots 147. According to this, the screen information on which the screen is enlarged or reduced is sent to the display driver 130a (130) so that the screen is displayed. That is, two screens are combined into one screen to be enlarged or reduced.

(B) of FIG. 44 shows an example in which two or more dots 147 select a pattern (or image) 147b. Even when the pattern (or image) 147b spans two screens, it is recognized as if it is on one screen.

Here, the dot is a point indicating a location where information is input when information is input on the screens of the display (2) (4).

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

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

If the above movement is programmed with mapangi, the central processing unit 105 or the control unit 110 moves the pattern (or image) 147b by the movement of the dot, and of this pattern (or image) 147b The movement is like moving on one screen.

In (C), the case of the point 147 moving left and right and the case of rotation are shown. When rotating, the selected pattern (or image) 147b can be rotated.

44(D) shows an example in which one point 147 moves. Even if the moving path 147a passes through two screens, it is like moving within one screen.

If the screen is programmed to change according to the movement path of the dot, the CPU 105 or the controller 110 sends information about the previous screen or the next screen to the display driver 130 (130a) by the movement of the dot. The given screen can be displayed.

Similarly, if the moving path 147a of the point 147 rotates, the rotation surface can also rotate.

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

In (A) of FIG. 45, when the point 147 moves within one screen, the screen is displayed along the movement path 147a, but in this case, the result is displayed only within one screen.

45(B) shows selection of one pattern (or image) 147b within one screen. In addition, the pattern (or image) 147b may move within one screen or another screen according to the movement path 147a of the dot 147 .

FIG. 46 is a view defining the height of the protection means 14 (or the side wall or extension) between the two input devices 200 and 400 (or two protection plates may be provided).

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

And, instead of the protection means 14, the side walls of the panel housings 10 and 40 may be provided, and the cover side walls 24d or side wall extensions 24a extending from the cover frame (or frame) may come. .

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

47 is a diagram 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 microsensors inserted into display pixels, and a set of microsensors inserted into the first display 2 is referred to as a first sensor and a microsensor inserted into the second display 4. A set of may be referred to as a second sensor.

At this time, controlling the input device means sending a current to the input device and detecting at which coordinate information is input when information is input to the input device. This detection is performed through the input device driving unit 140 and the central processing unit 105.

Select one screen mode or two screen mode. (Step 310)

In the single screen mode, the first and second displays are driven like one display, and the first and second input devices (or sensors) are also controlled like 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 the location corresponding to the coordinate values of the combined screen is compared with the coordinate values input through the input device (sensor), so that the central processing unit or the control unit displays It is to run the program to display on .

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

In the single screen mode, it is determined whether the coordinate values input through the input device (or sensor) have selected the coordinate values of the pattern (or image) displayed on the display (step 315).

If no pattern (or image) is selected, the program runs as if information was input through one input device, even if the input point and the movement path of the input point are both in the first and second input devices (or sensors). (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 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 in both the first and second input devices (or sensors), the selected pattern (or image) is like the input of one input device 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 control unit executes a predetermined program according to the number of dots or the moving path of the dots.

And, if the two-screen mode is selected in the previous step 310, the program determined according to whether a pattern (or image) is selected in the two-screen mode, the number of input points, and the movement path is executed (step 330).

That is, as in the example of the previous drawing, the program is executed according to the number of points input and the moving path of the points in the two screen mode.

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

On the other hand, even if the first and second displays are used as separate screens to execute the program, the program determined according to the input points and the moving paths of the points is executed, and the result of the execution is 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 diagram explaining the principle of making two devices into one.

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

However, controlling two input devices as one input device means connecting coordinates that are actually separated as shown in (B).

As shown in FIG. 50, the outer surface (D) of the thickest part of the panel housing is connected to the axis by a curved surface (C) or an inclined surface (C).

On the other hand, for the robustness of the shaft, a shaft having a certain thickness can provide more reliability. Therefore, the diameter (B) of the shaft is 0.25 times or more of the thickest part (A) of the panel housing (20, 40). It is good. That is, when the value of "B" is 0.25 times or more of the value of "A", design stability is brought about. Naturally, the value of "B" should not be greater than the value of "A".
