In this embodiment, the operating device 11 can be, for example, a stylus, or a wafer card, or a short-range wireless reading device, or a user (especially a user's hand). When the operating device 11 is an electronic device, it may have a function circuit such as a processing control circuit, a storage circuit or a transmitting circuit. Here, the "circuit" may be constituted by a hardware, a soft body, or a firmware, or a combination thereof.

2 is a side elevational view of matrix display device 12. As shown in FIG. 2, the matrix display device 12 includes a display surface 121 and a matrix substrate 122. The matrix substrate 122 includes a substrate 123 and a matrix 124. The matrix 124 is disposed on one side of the substrate 123, and the display surface 121 is located on the other side of the substrate 123. In the present embodiment, the display surface 121 refers to the surface of the matrix display device 12 closest to the user when the user views the matrix display device 12 to display an image.

3 is a schematic view of a thin film transistor substrate used in the present embodiment. Referring to FIG. 2 and FIG. 3 simultaneously, the matrix 124 may include a plurality of row electrodes S ₁ -S _M , a plurality of column electrodes D ₁ -D _N , and a plurality of pixel electrodes E ₁₁ -E _MN , and the row electrode systems and the same The column electrodes are staggered and are substantially perpendicular or at an angle to each other. In addition, the matrix 124 may further include a plurality of transistors T ₁₁ -T _MN , respectively, and the row electrodes S ₁ -S _M , the column electrodes D ₁ -D _N , and the pixel electrodes E ₁₁ -E _MN Sexual connection. Here, the row electrodes S ₁ to S _M are so-called scanning lines, and the column electrodes D ₁ to D _N are so-called data lines. In addition, a driving module can be further disposed on the substrate 123, and includes a data driving circuit, a scanning driving circuit, a timing control circuit (not shown), and a gamma correction circuit (not shown), which can be driven by the driving module. The LCD panel displays the image. Since the driving of the image by the driving module is a conventional technique, it will not be described here. In addition, the matrix substrate of this aspect is merely illustrative and is not intended to limit the present invention. The focus of this embodiment is to transmit the encoded signal from the matrix substrate to the operating device by using the row electrodes S ₁ -S _M and/or the column electrodes D ₁ -D _N to generate a transmission signal. Note that the encoded signal can imply different messages to correspond to different applications. From the reference coordinates of the display screen to the file data of various formats such as personal data, music, pictures, etc., it can be implicitly transmitted in the encoded signal.

In this embodiment, the column electrodes D ₁ -D _N can transmit the encoded signals in addition to the data signals of the display screen. For example, a display signal signal is directly superimposed with a coded signal higher than the frequency of displaying the data signal or a neutral time at which the display data signal is transmitted, for example, after all the row electrodes S ₁ to S _{M are} scanned, before the next scan is continued. Time (the gap time between the frame and the frame); either before a line electrode scan is completed and before the next one starts scanning; or during each line electrode scan time, the display data is shortened and the data signal is transmitted. Waiting before. Here, the encoded signal can be provided by extended timing control (T-con) circuit functions as well as data or scan drive circuits to simplify circuit design.

4 is a schematic diagram of signals of adjacent two rows of electrodes and adjacent two columns of electrodes. The row electrodes S ₁ -S _M respectively transmit the scanning signals SS to sequentially turn on the transistors of each column, and in the time when each column of transistors is turned on, the column electrodes D ₁ -D _N respectively transmit the encoded signals ES and display data. Signal DS. Hereinafter, the coded signal ES will be described by taking the one-dimensional touch control perpendicular to the column electrode direction as an example and timing coding. The same method can also be applied perpendicular to the direction of the row electrodes, thus forming a complete two-dimensional planar touch. In this embodiment, as shown in FIG. 4, when one row of electrodes transmits their scanning signals, only one column of electrodes transmits the encoded signal ES. In the figure, the coded signal FS is marked in a different level from the display data signal DS, and can be implemented in the same level. In addition, the coded signals ES are exemplified by the same polarity, and the coded signals ES have the same polarity as the display data signals DS; in other embodiments, the coded signals ES and the display materials The signal DS can have opposite polarities, that is, the coded signals ES have polarity reversal characteristics similar to those of the display data signals DS, so as to avoid a DC bias of the same polarity under long-term operation and thus affect the display image quality.

In this way, the timing chart of the encoded signal transmitted on each column electrode can be as shown in FIG. 5 (the data signal for display is omitted), and the column electrodes D ₁ to D _N respectively transmit the encoded signal ES1 when the row electrode transmits the scanning signal. ~ESN. It should be added that the above coded signals can be transmitted on different column electrodes respectively, or a plurality of column electrodes can transmit the same coded signal. For example, the column electrodes D ₁ to D ₃ can transmit the coded signal ES1; the same principle can also be applied to The encoded signal transmitted by the row electrode. In addition, the coded signals transmitted by the row electrodes and the column electrodes can be independently formed into a system. Since the column electrodes sequentially transmit the coded signal ES, it is necessary to obtain a reference point for a time, and the column electrode position can be known by comparison with the reference point. This reference point can be a special code transmitted in the same way, for example, all column electrodes transmit two 1s before starting the sequential transmission. In the above manner, the coded signal to which the operating device is coupled is, for example, 110010000, and the operating device is located at the third column electrode, so that the coordinates (X coordinate) of the operating device can be derived. In the same way, the Y coordinate of the operating device can be known via another set of encoded signals applied to the row electrodes. In addition, since the scanning signals applied by the row electrodes for driving the display data signals are sequentially generated, the scanning signals can be regarded as the encoded signals of the row electrodes of the present invention. The reference point required for the coded signal of the row electrode can be shared with the column electrode, for example, using horizontal or vertical sync signals for the display screen. Of course, the column electrodes D ₁ -D _N and the row electrodes S ₁ -S _M may additionally transmit more complicated coded signals, and details are not described herein.

In addition, the duty cycle of the encoded signal in this embodiment is less than the duty cycle of the data signal, thereby maintaining display quality.

When the user operates the display device 121 on the display surface 121 of the matrix display device 12 (e.g., touches the display surface or approaches the display surface), the encoded signal can be capacitively coupled from the matrix substrate 122 to the operating device 11. For example, the column electrode D ₁ -D _N transmits the coded signal ES as an example, so that the column electrode serves as one of the capacitive coupling electrodes, and the operating device 11 has another electrode capacitively coupled, for example, the operating device 11 is When the stylus is used, the tip contains a conductor as the other electrode for capacitive coupling.

After the operating device 11 receives the encoded signal ES by capacitive coupling, the operating device 11 processes the encoded signal ES to obtain a transmitted signal TS. The processing may include amplifying and/or decoding the encoded signal ES to interpret which column electrode is touched, or to interpret the touch position, or to interpret the touch gesture (hand gesture), or to interpret the touch The function instructions corresponding to the control. Note that the coded signal ES is capacitively coupled to the operating device 11. The size of the capacitor is related to the distance between the operating device and the display surface, that is, the Z-axis information can be obtained from the signal size, so that the operating device 11 can obtain not only the plane 2 The dimensional coordinates also include the Z coordinate with the plane distance. Accordingly, the coverage of the so-called transmission signal TS can be from the pair coding The signal ES is simply amplified to the last processed into an action command.

Then, after the operating device 11 generates the transmission signal TS, the operating device 11 can transmit the transmission signal TS to the matrix display device 12 by wire or wirelessly, or electrically coupled (including capacitive coupling) or optically coupled. Other relay devices or other devices other than the visual interface system are exemplified by direct transmission to the matrix display device 12.

When the present invention is applied to other non-touch applications, the message to be transmitted is first encoded into the encoded signal ES according to a specific principle, and then coupled to the operating device 11 by the matrix substrate 122 (for example, included in a mobile phone or a tablet). (eg a close-range wireless reader fixed to the wall). Similarly, the operating device 11 processes (for example, decodes and/or modifies data) the encoded signal ES according to the set principle to obtain the transmission signal TS, and then uses the transmission signal TS according to the respective use, for example, for access control, shopping and financial transactions. , file transfer, etc.

The above is processed by the operating device 11 to obtain information that the transmission signal TS already has, such as touch information, command information, identification information, transaction information, file information or other information. In addition, in other embodiments, the matrix display device 12 can process the transmission signal TS to obtain an information signal, and the information signal has touch information, command information, identification information, transaction information, file information or other information, that is, information signals. Only complete information is included.

As described above, referring to FIG. 1, the signal is transmitted from the coded signal ES to the operating device 11 to generate the transmission signal TS, and then the signal TS is transmitted to the matrix display device 12 to obtain the information signal. Processing, such as amplification and decoding, and these processes can be concentrated Or the operating device 11 or the matrix display device 12, such that the transmission signal TS has touch information, command information, identification information, transaction information, file information or other information, or the information signal has touch information, instruction information, identification information , trading information, file information or other information.

In addition, a response signal RS can be transmitted between the operating device 11 and the matrix display device 12. The response signal RS can be used to notify the matrix display device 12 of the receiving state of the operating device 11 or a message notification operation. The device 11 is ready to receive signals; it can also be a synchronization signal between the operating device 11 and the matrix display device 12. This creates an interactive chat mechanism between signal transmission and reception. In addition, the response signal RS can also serve as a synchronization function for both to form an information handshaking process.

FIG. 6 is a schematic diagram of the appearance of a matrix display device 12 of a visual interface system according to a first embodiment of the present invention. As shown in FIG. 6, the visual interface system further includes a mode triggering device 127. A user or operating device can trigger the mode triggering device 127 to activate the matrix display device 12 to enter an operational mode to transmit the encoded signal ES. Taking the touch as an example, when the user needs to utilize the touch function, the mode triggering device 127 is touched to start the matrix display device 12 to enter the touch mode. At this time, the row electrode or the column electrode transmits the encoded signal, and the rest of the time can turn off the touch function of all or part of the matrix display device 12, thereby preventing the touch screen from causing malfunction and saving power. Note that the operating mode of the sensing device 127 can have various modes, such as a state after a single trigger, a state before the recovery, a state change every time the trigger is triggered, and a state is maintained after the continuous trigger. Also need to pay attention The mode triggering device 127 can also be disposed on the operating device (for example, a switch on the stylus). In this case, after the mode triggering device 127 is triggered, the operating device 11 transmits a trigger signal to the matrix display device. 12 to put it into touch mode. It should be noted that the mode triggering device 127 referred to herein may be a single-trigger mode to switch the touch function, or the user must maintain contact to switch the touch function. In addition, taking the access control, ticket card, credit card, or file transfer as an example, the user can trigger the device to trigger the device to perform the identity transfer data transfer function by using the number signal, for example, transferring the data to the card reader, or another A device with a receiver. The mode triggering device 127 can be, for example, a mechanical switch, or a touch switch or the like.

The user operating device simultaneously contacts the display surface 121 of the matrix display device 12 and the sensing device 128 to transmit the transmission signal TS to Matrix display device 12. It is intended that the user transmits the transmission signal TS to the matrix display device 12 as a conductor. The actual action can be, for example, the right hand of the user operating on the display surface 121, while the left hand presses the sensing device 128 so that the encoded signal ES can be accessed from the right hand of the user and the transmitted signal TS can be transmitted from the left hand. The sensing device 128 can also have the function of the mode triggering device 127. For example, when the left hand is pressed and held by the sensing device 128, the working mode is started, and the rest of the time is not. This can greatly reduce power consumption and false touches.

Here, the user transmits the transmission signal TS to the relay device 13 and then transfers the relay processing signal IS to the matrix display device 12, but the technical features described below can be Multiple relays. Of course, when the operating device 11 is a user, the user can transmit the transmission signal TS to the relay device 13 for signal transmission, and can no longer return the signal to the matrix display device 12. In this case, the relay device 13 can be a mobile communication device, such as a mobile phone, so that the user can use the medium to transmit the encoded signal ES sent by the matrix display device 12 to the relay device 13 for use in the file. Transmission of data.

The relay device 13 processes the transmission signal TS to obtain a relay processing signal IS, and transmits the relay processing signal IS to the matrix display device 12.

In the process, the signals are subjected to some processing, such as amplification, decoding, modification, interpretation, etc., and these processes may be concentrated or dispersed in the operating device 11, the matrix display device 12 or the relay device 13. As a result, the transmission signal TS has touch information, instruction information, identification information, transaction information, file information or other information; or the relay processing signal IS can have touch resources Information, command information, identification information, transaction information, file information or other information; or, the information signal has touch information, instruction information, identification information, transaction information, file information or other information.
