Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a display screen driving architecture and method. Background Art

[0002] In recent years, the touch screen display market has entered a period of product diversification, ranging from small-sized mobile phones to medium- and large-sized laptops, tablets, car-mounted products and even IT products.

[0003] Touch technology is mainly divided into two types: out-cell and in-cell. For mobile phones, tablets and notebook computers, in-cell touch products are gradually replacing out-cell touch products due to cost, weight and thickness considerations.

[0004] At present, embedded touch products are gradually developing towards medium and large-sized products, and the requirements for touch functions are getting higher and higher, especially for products such as active pens, which require higher touch accuracy, which requires improving the resolution of the touch panel. Increasing the resolution of the touch panel will inevitably increase the number of touch signal control lines, and the space between the working area (AA area) of the touch panel and the side area (border) between the touch IC chip is limited, so it is a big challenge to optimize the number of touch signal control lines while ensuring the resolution of the touch panel.

[0005] like Figure 1 As shown, the conventional embedded touch display screen is designed with one touch sensor connected to one touch signal control line. Each touch signal control line independently controls one touch sensor, and the number of touch signal control lines is equal to the number of touch sensors. For example, touch signal control line RX1 controls touch sensor sensor1, touch signal control line RX2 controls touch sensor sensor2, touch signal control line RX3 controls touch sensor sensor3, and so on. The touch signal control line outputs and receives the touch signal of the corresponding touch sensor. The touch signal control line is connected to the touch IC chip through the lower side (border) of the touch panel.

[0006] like Figure 2As shown, the touch panel 100 is stacked on top of the pixel panel 200. The pixel panel includes pixel light-emitting units and pixel GIP driving circuits. The pixel light-emitting units are distributed in a matrix and are located in the working area of ​​the pixel panel. The pixel GIP driving circuit is located on the left side of the pixel panel. One pixel GIP driving circuit controls a row of pixel light-emitting units. Multiple pixel GIP driving circuits are connected in stages. The pixel GIP driving circuit scans and drives the pixel light-emitting units row by row. For an LCD display screen, the pixel light-emitting unit includes a pixel TFT and a liquid crystal. The pixel GIP driving circuit transmits a signal to the gate of the pixel TFT through a horizontally arranged scanning line to control the on and off of a row of pixel TFTs. The source of the pixel TFT is connected to the data signal line arranged vertically, and the drain of the pixel TFT is connected to the liquid crystal. When the pixel TFT is in the on state, the voltage signal of the data signal line is sent to the liquid crystal. The output signal of the pixel GIP driving circuit at this level will not only be transmitted to the gate of the pixel TFT of the corresponding row, but also participate in the work of the pixel GIP driving circuits of the previous and next levels.

[0007] For conventional embedded touch display screens, when the resolution of the touch panel is larger, the number of touch sensors is greater, and the number of touch signal control lines is greater. The touch signal control lines occupy more space on the bottom side (border) of the touch panel, and more space must be reserved for the bottom side of the touch panel when designing the touch panel; this is not conducive to making a touch panel with narrow edges.

[0008] Therefore, how to ensure the resolution requirement of the embedded touch panel and reduce the number of touch signal control lines is a technical problem that needs to be solved urgently in the art. Summary of the invention

[0018] The touch sensor is located in the working area of ​​the touch panel, and the touch GIP driving circuit and the touch signal control line are both located in the left side area of ​​the touch panel;

[0019] The touch panel is stacked on the pixel panel.

[0020] Furthermore, it also includes a touch IC chip, and the touch IC chip is connected to the touch signal control line.

[0021] Furthermore, the touch signal switch is a thin film field effect transistor.

[0022] Furthermore, the touch signal switch and the touch sensor are connected via a transparent conductive wire.

[0023] Furthermore, the pixel light emitting unit includes liquid crystal and a pixel TFT, the output end of the pixel GIP driving circuit is connected to the gate of the pixel TFT, the source of the gate of the pixel TFT is connected to the data signal line, and the drain of the gate of the pixel TFT is connected to the liquid crystal.

[0024] Further, in the touch panel, one row of the touch sensors corresponds to one touch GIP driving circuit and N touch signal switches, and the control ends of the N touch signal switches are all connected to the output end of one touch GIP driving circuit;

[0025] There are M touch GIP driving circuits in total, and the M touch GIP driving circuits are connected in stages.

[0027] During the display time of one frame, first all pixel GIP driving circuits drive the pixel light-emitting units row by row, and then all touch GIP driving circuits drive the touch signal switches row by row. The touch GIP driving circuits in the same row drive the touch signal switches in the same row at the same time.

[0028] Furthermore, the touch GIP driving circuits in the same row drive the touch signal switches in the same row in sequence.

[0029] Further, one row of the touch sensors is provided with Q rows of pixel light emitting units, Q is an integer greater than or equal to 2, and the number of rows R of the pixel light emitting units is Q times the number of rows M of the touch sensors;

[0032] Then, when the pixel GIP driving circuit of the Mth group drives the pixel light-emitting units of the Mth group row by row, the touch GIP driving circuit of the M-1th row drives the touch signal switches of the M-1th row;

[0033] Finally, when all the pixel light emitting units are driven, the touch GIP driving circuit in the Mth row drives the touch signal switches in the Mth row.

The number of touch signal control lines is equal to the number of columns of touch sensors distributed in the matrix, ensuring the resolution requirement of the embedded touch panel and reducing the number of touch signal control lines.

[0045] The embodiments of the present invention provide a display screen driving architecture and method, which overcome the disadvantages in the background technology that the number of touch signal control lines is equal to the number of touch sensors, and when the touch panel requires high resolution, there are more touch signal control lines, which occupy more panel side space; it achieves the technical effect of ensuring the resolution requirement of the embedded touch panel and reducing the number of touch signal control lines. Under the condition of the same resolution, the number of touch signal control lines of the present invention is small, which is conducive to the production of a narrow-edge touch panel.

[0046] The overall idea of ​​the technical solution of the embodiment of the present invention is as follows:

[0047] Referring to the row-by-row scanning working mode of the pixel GIP driving circuit, the connection between one touch sensor and one touch signal control line in the background technology is changed to one control signal line corresponding to one column of touch sensors. One touch signal control line is connected to one column of touch sensors one by one and sends and receives signals, which greatly reduces the number of touch signal control lines.

[0048] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] See also Figures 1 to 7 , a preferred embodiment of the present invention.

[0050] A display screen driver architecture, comprising:

[0051] A touch panel 100, wherein the touch panel 100 includes a touch sensor, a touch GIP driving circuit, a touch signal switch and a touch signal control line;

[0052] The touch sensors are arranged in a matrix of M rows and N columns, the N touch signal control lines correspond to the N columns of touch sensors respectively, each of the touch signal control lines is allocated with M touch GIP driving circuits, and the M touch GIP driving circuits are connected in stages, each of the touch GIP driving circuits is allocated with a touch signal switch, and the M touch signal switches correspond to the M touch sensors respectively;

[0053] The control end of the touch signal switch is connected to the output end of the touch GIP driving circuit, the first signal transceiver end of the touch signal switch is connected to the corresponding touch signal control line, and the second signal transceiver end of the touch signal switch is connected to the corresponding touch sensor;

[0054] The M and N are both integers greater than or equal to.

[0055] The beneficial effect of the technical solution of the present invention is that: referring to the working mode of row-by-row scanning of the pixel GIP driving circuit, the driving mode of the touch signal control line is optimized, so that a touch signal control line is connected to a column of touch sensors one by one and sends and receives signals, the number of touch signal control lines is equal to the number of columns of touch sensors distributed in the matrix, ensuring the resolution requirement of the embedded touch panel and reducing the number of touch signal control lines. In this way, the space occupied by the touch signal control line on the side of the touch panel is reduced, which is conducive to the production of narrow-edge touch panels and improves the market competitiveness of the panels.

[0056] When the control end of the touch signal switch is at a high level, the first signal receiving and transmitting end of the touch signal switch is connected to the second signal receiving and transmitting end; when the control end of the touch signal switch is at a low level, the first signal receiving and transmitting end of the touch signal switch is disconnected from the second signal receiving and transmitting end.

[0057] The working mode of the touch GIP driving circuit refers to the working mode of the pixel GIP driving circuit.

[0058] Combination Figure 4, for example, M is three, and N is two. The touch sensors are arranged in a matrix of three rows and two columns, and the number of touch sensors is six in total, namely sensor1, sensor2, sensor3, sensor4, sensor5, and sensor6. The number of the touch signal control lines is two, namely RX1 and RX2. The touch signal control line RX1 is allocated with three touch GIP driving circuits, namely TP_GIP1, TP_GIP3, and TP_GIP5. The touch signal control line RX2 is allocated with three touch GIP driving circuits, namely TP_GIP2, TP_GIP4, and TP_GIP6. The number of the touch signal switches is six, namely T1, T2, T3, T4, T5, and T6.

[0059] The output end of the touch GIP driving circuit TP_GIP1 first sends a high-level signal to the touch signal switch T1, so that the touch signal control line RX1 is connected to the touch sensor sensor1; then the output end of the touch GIP driving circuit TP_GIP1 sends a low-level signal to the touch signal switch T1, and at the same time, the output end of the touch GIP driving circuit TP_GIP3 sends a high-level signal to the touch signal switch T3, so that the touch signal control line RX1 becomes connected to the touch sensor sensor3; then the output end of the touch GIP driving circuit TP_GIP3 sends a low-level signal to the touch signal switch T3, and at the same time, the output end of the touch GIP driving circuit TP_GIP5 sends a high-level signal to the touch signal switch T5, so that the touch signal control line RX1 becomes connected to the touch sensor sensor5. Finally, the touch signal control line RX1 is connected back to the touch sensor sensor1.

[0060] Similarly, the touch GIP driving circuits TP_GIP2, TP_GIP4, and TP_GIP6 drive the corresponding touch signal switches T2, T4, and T6 one by one, so that the touch signal control line RX2 is sequentially connected to the touch sensors sensor2, sensor4, and sensor6. Since the line-by-line scanning speed is very fast, the user cannot see the delay.

[0061] Combined with background technology Figure 1 , six touch sensors sensor1, sensor2, sensor3, sensor4, sensor5, sensor6 require six touch signal control lines RX1, RX2, RX3, RX4, RX5, RX6. Figure 4 In the present invention, the six touch sensors sensor1, sensor2, sensor3, sensor4, sensor5, and sensor6 only need two touch signal control lines RX1 and RX2.

[0062] For example, when M is six and N is four, the touch sensor is arranged in a matrix of six rows and four columns, and the number of the touch signal control lines is four. Each touch signal control line is allocated with six touch GIP driving circuits and six touch signal switches.

[0063] Also included is a pixel panel 200, the pixel panel including a pixel light emitting unit and a pixel GIP driving circuit;

[0064] The pixel light emitting units are arranged in a matrix of R rows and S columns, the R pixel GIP driving circuits correspond to the pixel light emitting units in the R rows respectively, the R pixel GIP driving circuits are connected in stages, the pixel light emitting units are located in the working area 201 of the pixel panel, and the pixel GIP driving circuits are located in the left side area 202 of the pixel panel;

[0065] Said S and R are both integers greater than or equal to 2;

[0066] The touch sensors (sensor1, sensor2, sensor3, sensor4, sensor5, sensor6) are located in the working area 101 of the touch panel, and the touch GIP driving circuits (TP_GIP1, TP_GIP2, TP_GIP3, TP_GIP4, TP_GIP5, TP_GIP6) and touch signal control lines (RX1, RX2) are all located in the left side area 102 of the touch panel;

[0067] The touch panel 100 is stacked on the pixel panel 200. The beneficial effect of this technical solution is that the touch GIP driving circuit and the pixel GIP driving circuit are both located on the left side of the corresponding panel, and the touch GIP driving circuit is located above the pixel GIP driving circuit, which effectively utilizes the panel space and helps to narrow the edge of the display screen.

[0068] For example, R is ninety, and S is sixty. The pixel light-emitting units are arranged in a matrix of ninety rows and sixty columns; there are ninety pixel GIP driving circuits, and the pixel GIP driving circuits scan and drive the pixel light-emitting units row by row. The pixel light-emitting units corresponding to the pixel GIP driving circuits GIP1 to GIP30 are located below the touch sensors sensor1 and sensor2; the pixel light-emitting units corresponding to the pixel GIP driving circuits GIP31 to GIP60 are located below the touch sensors sensor2 and sensor4; the pixel light-emitting units corresponding to the pixel GIP driving circuits GIP61 to GIP90 are located below the touch sensors sensor5 and sensor6.

[0069] According to the actual display screen, either the pixel light-emitting units corresponding to the pixel GIP driving circuits GIP1 to GIP15 are located below the touch sensors sensor1 and sensor4; or the pixel light-emitting units corresponding to the pixel GIP driving circuits GIP1 to GIP40 are located below the touch sensors sensor1 and sensor4.

[0070] The device further comprises a touch IC chip (not shown), wherein the touch IC chip is connected to the touch signal control line.

[0071] The touch signal switch is a thin film field effect transistor.

[0072] The touch signal switch and the touch sensor are connected via a transparent conductive wire, which is made of ITO.

[0073] The pixel light emitting unit includes liquid crystal and a pixel TFT, the output end of the pixel GIP driving circuit is connected to the gate of the pixel TFT, the source of the gate of the pixel TFT is connected to the data signal line, and the drain of the gate of the pixel TFT is connected to the liquid crystal.

[0074] In another embodiment of the present invention, in the touch panel 100, a row of the touch sensors corresponds to one touch GIP driving circuit and N touch signal switches, and the control ends of the N touch signal switches are all connected to the output end of one touch GIP driving circuit;

[0075] There are M touch GIP driving circuits in total, and the M touch GIP driving circuits are connected in stages. Figure 5 , the first row of touch sensors sensor1 and sensor2 correspond to a touch GIP driving circuit TP_GIP1 and two touch signal switches T1 and T2, and the control ends of the two touch signal switches T1 and T2 are connected to the output end of the touch GIP driving circuit TP_GIP1. Similarly, the second row of touch sensors sensor3 and sensor4 correspond to a touch GIP driving circuit TP_GIP2 and two touch signal switches T3 and T4. The third row of touch sensors sensor5 and sensor6 correspond to a touch GIP driving circuit TP_GIP3 and two touch signal switches T5 and T6.

[0076] The beneficial effect of this technical solution is that the number of touch GIP driving circuits is reduced and the manufacturing cost is saved; when the touch signal control line RX1 is connected to the touch sensor sensor1, the touch signal control line RX2 is connected to the touch sensor sensor2; when the touch signal control line RX1 is disconnected from the touch sensor sensor1, the touch signal control line RX2 is disconnected from the touch sensor sensor2.

[0077] A display screen driving method, using the display screen driving architecture, comprising:

[0078] During the display time of one frame, first all pixel GIP driving circuits drive the pixel light-emitting units row by row, and then all touch GIP driving circuits drive the touch signal switches row by row. The touch GIP driving circuits in the same row drive the touch signal switches in the same row at the same time.

[0079] When the touch signal switches located in the same row are in the on state, the N touch sensors located in the same row are respectively connected to the N touch signal control lines, so that the touch signal control lines receive and process the touch signals of this row; when the touch signal switches located in the same row are in the off state, the N touch sensors located in the same row are respectively disconnected from the N touch signal control lines, so that the touch signal control lines do not receive and process the touch signals of this row.

[0080] For example, the touch sensor is arranged in a matrix of three rows and two columns, and the pixel light emitting unit is arranged in a matrix of ninety rows and sixty columns. After the pixel TFTs of the pixel light emitting units in the ninety rows receive the conduction signal from top to bottom, the touch signal switches corresponding to the touch sensors in the three rows receive the conduction signal from top to bottom. The two touch sensors in each row are connected to the two touch signal control lines at the same time.

[0081] In another embodiment of the present invention, the touch GIP driving circuits in the same row sequentially drive the touch signal switches in the same row. For example, in the first row, the touch signal control line RX1 is first connected to the touch sensor sensor1, and the touch signal control line RX2 is then connected to the touch sensor sensor2; then in the second row, the touch signal control line RX1 is first connected to the touch sensor sensor3, and the touch signal control line RX2 is then connected to the touch sensor sensor4; finally, in the third row, the touch signal control line RX1 is first connected to the touch sensor sensor5, and the touch signal control line RX2 is then connected to the touch sensor sensor6.

[0082] Further, one row of the touch sensors is provided with Q rows of pixel light emitting units, Q is an integer greater than or equal to 2, and the number of rows R of the pixel light emitting units is Q times the number of rows M of the touch sensors;

[0083] The pixel light emitting units in the Q rows and the pixel driving circuits in the Q rows are grouped as one group;

[0084] In a display time of one frame, first, when the first group of pixel GIP driving circuits drives the first group of pixel light-emitting units row by row, all the touch control GIP driving circuits do not work;

[0085] Then, when the pixel GIP driving circuit of the Mth group drives the pixel light-emitting units of the Mth group row by row, the touch GIP driving circuit of the M-1th row drives the touch signal switches of the M-1th row;

[0086] Finally, when all the pixel light emitting units are driven, the touch GIP driving circuit in the Mth row drives the touch signal switches in the Mth row.

[0087] For example, Q is thirty, R is ninety, and M is three. During the display time of one frame, the first group of thirty pixel GIP driving circuits (GIP1 to GIP30) drive the first group of thirty pixel light-emitting units row by row, and the output ends of all the touch GIP driving circuits do not send out conduction signals. Then the second group of thirty pixel GIP driving circuits (GIP31 to GIP60) drive the second group of thirty pixel light-emitting units row by row. At this time, the first row of touch GIP driving circuits (TP_GIP1, TP_GIP2) drive the first row of touch signal switches (T1, T2), and the touch signal control lines RX1 and RX2 are connected to the touch sensors sensor1 and sensor2, respectively. Then the third group of thirty pixel GIP driving circuits (GIP61 to GIP90) drive the third group of thirty pixel light-emitting units row by row, at which time the second row of touch GIP driving circuits (TP_GIP3, TP_GIP4) drive the second row of touch signal switches (T3, T4), and the touch signal control lines RX1, RX2 are connected to touch sensors sensor3, sensor4 respectively. Finally, the output ends of all the pixel GIP driving circuits do not send a conduction signal to the pixel light-emitting units, at which time the third row of touch GIP driving circuits (TP_GIP5, TP_GIP6) drive the third row of touch signal switches (T5, T6), and the touch signal control lines RX1, RX2 are connected to touch sensors sensor5, sensor6 respectively.

[0088] Working method of the present invention: Combination Figure 4, a touch GIP driving circuit (TP_GIP1 to TP_GIP6) is added next to the pixel GIP driving circuit (GIP1 to GIP90) on the left side of the original display screen. A touch GIP driving circuit controls one of the touch sensors in a row. The touch sensors in the same column are controlled by the same touch signal control line through the corresponding touch GIP driving circuit. When the touch GIP driving circuit (TP_GIP1, TP_GIP3, TP_GIP5) outputs row by row, the touch signal control line RX1 can control the touch sensors sensor1, sensor3, and sensor5 in turn. Similarly, the touch signal control line RX2 controls the touch sensors sensor2, sensor4, and sensor5 in turn. Figure 4 There are a total of six touch sensors, and only two touch signal control lines RX1 and RX2 are needed; far less than conventional structures, such as Figure 1 As shown, the required six touch signal control lines (RX1 to RX6) significantly reduce the number of touch signal control lines.

[0089] When the display screen driving architecture of the present invention is adopted, the original touch signal control line driving timing also needs to be adjusted accordingly, such as Figure 3 As shown, the conventional driving timing of the touch signal control line is within one frame, after the pixels in the working area of ​​the pixel panel display work, the touch signal control line and the touch sensor are transmitted. Figure 6 As shown, in the present invention, the driving timing of the touch signal control line is also within the time of one frame. After the pixels in the working area of ​​the pixel panel are displayed, since the touch GIP circuit needs to output row by row, the signal of the touch signal control line needs to be separately touched row by row, thereby meeting the touch timing requirements of the present invention. By comparing the driving timing of the new and old touch signal control lines, it can be seen that the present invention reduces the number of touch signal control lines while shortening the sensing time of the touch signal control line connecting to the touch sensor. To address this defect, the driving timing of the dedicated touch signal control line of the present invention can be further developed, such as Figure 7 As shown, after the pixel GIP driving circuit GIP30 level output ends, the touch sensor sensor1 / 2 can start working, until the pixel GIP driving circuit GIP60 level output ends, the touch sensor sensor1 / 2 stops working, and the touch sensor sensor3 / 4 starts working, and so on. In one frame, only the display level transmission time of the last row of touch sensors needs to be retained, and the remaining touch sensor time can be used as the pixel display working time, so as to maximize the pixel display work.

[0090] Combination Figure 3 , one frame time consists of display time and touch time. Figure 6, the sensing time of a single touch sensor of the improved version is the touch (sensor1 / 2, sensor3 / 4, sensor5 / 6) time divided by the number of touch GIP drive circuits; combined Figure 7 , the sensing time of a single touch sensor of the dedicated version is the display time divided by the number of touch GIP driving circuits, and the general display time is much longer than the touch time (sensor1 / 2, sensor3 / 4, sensor5 / 6), so the sensing time of a single touch sensor of the improved version will be much shorter than that of the dedicated version. Therefore, the driving timing of the touch signal control line of the dedicated version of the present invention can significantly increase the display time and touch time (sensor1 / 2, sensor3 / 4, sensor5 / 6) compared with the driving timing of the touch signal control line of the improved version of the present invention.

[0091] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
