The interface or PS/2 interface allows the touch panel control unit to be connected to the central processing unit. This saves a lot of cost and can easily manage the power of the display and the touch panel. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the two preferred embodiments of the drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. 2 is a first preferred embodiment of the electronic system 10 of the present invention. The electronic system 10 includes a touch display device 1 and a computer host 30. The touch display device 1 includes a two-wire serial interface 2 (/2C). An interface 11 electrically connected to the host computer 30 by a two-wire serial interface 2 and having a liquid crystal display panel 17 for displaying a picture, a touch panel 12 mounted in front of the liquid crystal display panel 17, and a The touch panel control unit 13 is mounted inside the display 11. It is worth mentioning that at present, there is a low-temperature polysilicon process technology (LTPS) that directly integrates the touch circuit into the display panel of the display during the process of manufacturing the liquid crystal display. The invention concept described below can also be applied to this new In terms of process technology, it should be familiar to those skilled in the art, so the new process technology will not be described. The display 11 has a read-only memory 14, and a timing controller 15 for receiving an image signal from the host computer 30 to control the display of the liquid crystal display panel 17 of the display 11; in the read-only memory 14, a display 11 is stored. In the embodiment, the display device information is an external display device identification data (EDID), and the EDID includes the support resolution, specifications, manufacturer, and the like of the display 11. . It should be noted that, in this embodiment, the read-only memory 14 is an electrically-erasable programmable read-only memory (hereinafter referred to as EEPROM), and the memory is not Need to use ultraviolet radiation, 201011607 can also use a specific voltage to wipe the information on the wafer to write new data without being removed, so it is widely used to store the monitor's Edid data 'but can also be of other kinds Memory storage' is not limited to EEPROM. The computer main unit 30 includes a central processing unit 3 (shown in phantom), and the central processing unit 3 has a graphic processing unit (Graphic Processing Unit 33) that is electrically connected to the read-only memory 14 and the timing controller 15. GPU), a central processing unit 31, and a bridged graphics processor 33 and a North Bridge 32 of the central processing unit. When the display 11 is connected to the host computer 30, the graphics processor 33 reads the EDID data about the display 11 through the second-line serial interface 2, and the graphics processor 33 can determine which specifications of the video signal to be sent to the display according to the EDID. The timing controller 15' of u controls the screen display of the liquid crystal display panel 17 of the display 11. After the graphics processor 33 reads the EDID data, it no longer captures the read-only memory 14 via the second-line serial interface 2. The data, and therefore the second-line sequence interface 2, is temporarily idle. The touch panel control unit 13 is electrically connected to the touch panel 12 and is electrically connected to the graphics processor 33 of the central processing unit 3 via the two-wire serial interface 2. When the touch panel 12 is touched by the user, the touch panel 12 can sense the touched contact position and transmit the information of the contact position to the touch panel control unit 13; the touch panel control unit 13 The contact position is resolved and a corresponding touch signal is generated and transmitted to the graphics processor 33 of the central processing unit 3 through the two-wire serial interface 2, and the touch signal is then transmitted to the central processor via the north bridge chip 32. 31. The central processing unit 201011607 31 causes the computer host 30 to generate a corresponding action according to the touch signal. Since the two-line serial interface 2 is already in the interposed state after the graphics processor 33 reads the eDII information, when the touch panel control unit 13 transmits the touch signal to the graphics processor 33, there is no Different signals interfere with each other in the second-line sequence interface 2. In this way, the touch panel 12 and the display u can share the data transmission line, eliminating the cost of having to connect the USB interface or the ps/2 interface. In addition, the touch panel control unit 13 can be mounted on the display. Within 11, it saves a lot of space. It is worth mentioning that the touch panel 12 mentioned in this embodiment may actually be a resistive touch panel, a capacitive touch panel, an acoustic wave touch panel, and an infrared touch panel. And any one of the drawing boards and the like, as long as any input interface mounted on the display u can be realized by the concept of the present invention, and is not limited to the embodiment. In addition to the foregoing functions, the embodiment also controls the touch of the display 11 when the graphics processor 33 turns off the backlight of the display 11, and the panel control unit 13 sets the touch panel 12 to enter the power saving mode; That is to say, while the user no longer watches the screen of the display 11, the touch panel ❿ 12 enters the power saving mode to save power, so that it is not necessary to set the touch panel 12 to the power saving mode after turning off the power of the display. The power of the display u and the touch panel 12 can be managed at the same time in one operation. It is worth mentioning that 'this embodiment is based on the brightness of the backlight of the display U, to determine whether the user still needs to use the touch surface & 12, but not limited thereto, and can also be controlled by the timing controller of the display 11 15 has stopped receiving the image signal from the graphics processor 33 to determine whether the user still needs to use the touch panel 201011607 control panel 12, and controls whether the touch panel 12 needs to enter the power saving mode. Referring to FIG. 3, the second preferred embodiment of the electronic system of the present invention has the same functions and most of the components as the first preferred embodiment. The difference is that in order to reduce the cost, the embodiment will The touch panel control unit A 13 of the first preferred embodiment, the read only memory unit 14 and the timing controller 15 are integrated in a system wafer 16, that is, the system chip magazine stores EDID data about the display U'. The graphics processor 33 can determine which format image signal is sent to the display u according to the EDID, and the system wafer 16 controls the display of the display 11'; and the system chip 16 also generates the touch signal. The two-line serial interface 2 is transmitted to the graphics processor 33 of the central processing unit 3, and the touch signal is then transmitted to the central processor 31 via the north bridge chip 32, and the central processing unit 31 transmits the signal to the computer host 30. Produce the corresponding action. Referring to FIG. 4, the third preferred embodiment of the electronic system of the present invention has the same functions and most of the components as the first preferred embodiment. The difference is that 'in order to further reduce the touch display device 1 The thickness of the display panel 17 and the touch panel 12 of the first preferred embodiment are integrated into an in-cell touch panel 18 by using the LTPS process technology, that is, the in-cell touch panel 18 is In the semiconductor process, another transparent conductive layer (ITO) is splashed on the existing transparent conductive electrode layer of the color filter substrate of the display panel to form a capacitive touch directly between the two layers. Control the touch sensor to reduce the thickness of one touch panel. Therefore, the in-cell touch panel 18 not only has a display function, but also can sense a touched contact position by using a capacitive touch sensing circuit directly formed thereon, and 11 201011607 The information is transmitted to the touch panel control unit u, so that the touch panel control unit 13 analyzes the contact position, and generates a corresponding touch signal transmitted to the central processing unit 3 through the two-line serial interface 2, and the central processing unit 31 Then, the computer-based host 30 generates a corresponding operation. It should be noted that the descriptions in the first, second, and third preferred embodiments are all described as touching the touch panel 12 - the point, and the sense of the position of the contact - but the invention does not limit this, of course, the user also touches the touch panel 12 multiple touch positions (Multrnmch) '" is the user The various gestures made on the touch panel 12 and the like can be analyzed by the touch panel control unit 13 and the corresponding input signals can be generated by the touch panel control unit 13 through the two-line serial interface 2 pass To the central processing unit 3. In summary, the effect of the present invention is to utilize the original data transmission path of the display, that is, the second-line serial interface for transmitting EDID data as the path for transmitting the touch signal, instead of the conventional USB. The interface or ps/2 interface allows the touch panel control unit to be connected to the central processing unit ,, which saves a lot of cost. In addition, the touch panel control unit can be installed in the display 11, saving a lot of space. In addition, it is also convenient to jointly manage the power of the display and the touch panel.
