Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and particularly relates to a display screen driving architecture. Background Art

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

[0003] Touch technologies are mainly divided into two types: external (Out cell) and embedded (In cell). For mobile phones, tablets, and laptop products, due to considerations of cost, weight, and thickness, embedded (In cell) touch products are gradually replacing external (Out cell) touch products.

[0004] Currently, embedded (In cell) touch products tend to develop towards medium and large-sized products, and the requirements for touch functions are getting higher and higher. Especially for products such as active pens, higher precision is required for touch functions, which requires increasing the resolution of the touch panel (Touch Panel). Increasing the resolution of the touch panel will inevitably require an increase in the number of touch signal control lines. However, the space in the side area (border) between the working area (AA area) of the touch panel and the touch IC chip is limited. Therefore, optimizing the number of touch signal control lines while ensuring the resolution of the touch panel is a major challenge.

[0005] As Figure 1 shown, in the conventional design of an embedded touch display screen, the routing is such that one touch sensor is connected to one touch signal control line, and each touch signal control line independently controls one touch sensor. The number of touch signal control lines is equal to the number of touch sensors. For example, the touch signal control line RX1 controls the touch sensor sensor1, the touch signal control line RX2 controls the touch sensor sensor2, the touch signal control line RX3 controls the touch sensor sensor3, and so on. The touch signal output and reception of the corresponding touch sensor are carried out by the touch signal control line. The touch signal control line is connected to the touch IC chip through the lower side (border) of the touch panel.

[0006] As Figure 2As shown in the figure, the touch panel 100 is stacked above the pixel panel 200. The pixel panel includes pixel light-emitting units and a pixel GIP driving circuit. 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 one row of pixel light-emitting units, and the multiple pixel GIP driving circuits are connected in a cascading manner; 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 liquid crystal. The pixel GIP driving circuit transmits signals to the gates of the pixel TFTs through horizontally arranged scanning lines to control the on and off of one row of pixel TFTs. The source electrodes of the pixel TFTs are connected to vertically arranged data signal lines, and the drain electrodes of the pixel TFTs are connected to the liquid crystal. When the pixel TFT is in the conducting 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 gates of the pixel TFTs in the corresponding row but also participate in the operation of the pixel GIP driving circuits at the previous and next levels.

[0007] For a conventional in-cell touch display screen, when the resolution of the touch panel is larger, the number of touch sensors is more, and then the number of touch signal control lines required is more. The space occupied by the touch signal control lines at the lower border of the touch panel is more, and more dimensions need to be reserved for the lower border of the touch panel when designing the touch panel; this is not conducive to manufacturing a narrow-border touch panel.

[0008] Therefore, how to ensure the resolution requirement of the in-cell touch panel and reduce the number of touch signal control lines is a technical problem urgently to be solved in this field. SUMMARY OF THE UTILITY MODEL

[0037] An embodiment of the present utility model provides a display screen driving architecture, which overcomes the drawback in the background art that the number of touch signal control lines is equal to the number of touch sensors. When a high-resolution touch panel is required, there are many touch signal control lines, occupying a large amount of space on the side of the panel. It achieves the technical effect of ensuring the resolution requirement of the inlaid touch panel, reducing the number of touch signal control lines. Under the condition of the same resolution, the number of touch signal controls in the present utility model is less, which is beneficial to the production of a narrow-edge touch panel.

[0038] The general idea of the technical solution of the embodiment of the present utility model is as follows:

[0039] Referring to the working mode of progressive scanning of the reference pixel GIP driving circuit, changing the connection mode in the background art where one touch sensor is connected to one touch signal control line to one control signal line corresponding to controlling one column of touch sensors, and one touch signal control line is sequentially connected to and communicates with one touch sensor in one column, greatly reducing the number of touch signal control lines.

[0040] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0041] Refer to Figures 1 to 7 , the preferred embodiment of the present utility model.

[0042] A display screen driving architecture, comprising:

[0043] A touch panel 100, the touch panel 100 includes touch sensors, a touch GIP driving circuit, a touch signal switch, and touch signal control lines;

[0044] The touch sensors are distributed in an M-row and N-column matrix. The N touch signal control lines respectively correspond to the N columns of touch sensors. Each touch signal control line is allocated M touch GIP driving circuits, and the M touch GIP driving circuits are connected in series. Each touch GIP driving circuit is allocated one touch signal switch, and the M touch signal switches respectively correspond to the M touch sensors;

[0045] 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;

[0046] Both M and N are integers greater than or equal to.

[0047] The beneficial effects of the technical solution of the present utility model are as follows: Referring to the working mode of the row-by-row scanning of the reference 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 and communicates with one column of touch sensors one by one. The number of touch signal control lines is equal to the number of columns of the matrix-distributed touch sensors, ensuring the resolution requirements of the inlaid touch panel and reducing the number of touch signal control lines. In this way, the space occupied by the touch signal control lines on the side of the touch panel is reduced, which is beneficial to the production of a narrow-edge touch panel and improves the market competitiveness of the panel.

[0048] When the control end of the touch signal switch is at a high level, the first signal transceiver end and the second signal transceiver end of the touch signal switch are conducted; when the control end of the touch signal switch is at a low level, the first signal transceiver end and the second signal transceiver end of the touch signal switch are disconnected.

[0049] The working mode of the touch GIP driving circuit refers to the working mode of the pixel GIP driving circuit.

[0050] Combined Figure 4 , for example, M is three and N is two. The touch sensors are distributed in a three-row and two-column matrix, and the total number of touch sensors is six, 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 three touch GIP driving circuits, namely TP_GIP1, TP_GIP3, and TP_GIP5. The touch signal control line RX2 is allocated 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.

[0051] The output end of the touch GIP driving circuit TP_GIP1 first sends a high-level signal to the touch signal switch T1 to connect the touch signal control line RX1 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 to make the touch signal control line RX1 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 to make the touch signal control line RX1 connected to the touch sensor sensor5. Finally, the touch signal control line RX1 is connected back to the touch sensor sensor1.

[0052] 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 connected to the touch sensors sensor2, sensor4, and sensor6 in sequence. Since the speed of progressive scanning is very fast, the user cannot perceive the delay with the naked eye.

[0053] Combined with the background art Figure 1 , six touch sensors sensor1, sensor2, sensor3, sensor4, sensor5, and sensor6 require six touch signal control lines RX1, RX2, RX3, RX4, RX5, and RX6. Combined with Figure 4 , in the present invention, six touch sensors sensor1, sensor2, sensor3, sensor4, sensor5, and sensor6 only require two touch signal control lines RX1 and RX2.

[0054] For example, when M is six and N is four, the touch sensors are distributed in a six-row and four-column matrix, and the number of the touch signal control lines is four. Each touch signal control line is allocated six touch GIP driving circuits and six touch signal switches.

[0055] It further includes a pixel panel 200, and the pixel panel includes pixel light-emitting units and pixel GIP driving circuits;

[0056] The pixel light-emitting units are distributed in an R-row and S-column matrix. R pixel GIP driving circuits respectively correspond to R rows of the pixel light-emitting units. The R pixel GIP driving circuits are connected in a cascaded manner. 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;

[0057] Both S and R are integers greater than or equal to two;

[0058] 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 the touch signal control lines (RX1, RX2) are both located in the left-side area 102 of the touch panel;

[0059] The touch panel 100 is stacked above the pixel panel 200. The beneficial effect of this technical solution is that both the touch GIP driving circuit and the pixel GIP driving circuit are located on the left side of the corresponding panel, and the touch GIP driving circuit is located above the pixel GIP driving circuit, effectively utilizing the panel space and contributing to the narrow bezel of the display screen.

[0060] For example, R is ninety and S is sixty. The pixel light-emitting units are distributed 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.

[0061] According to the actual situation of the 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.

[0062] It further includes a touch IC chip (not shown), and the touch IC chip is connected to the touch signal control line.

[0063] The touch signal switch is a thin-film field-effect transistor.

[0064] The touch signal switch is connected to the touch sensor through a transparent conductive wire. The transparent conductive wire is made of ITO material.

[0065] 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.

[0066] In another embodiment of the present invention, in the touch panel 100, one row of the touch sensors corresponds to one touch GIP driving circuit and N touch signal switches. The control ends of the N touch signal switches are all connected to the output end of one touch GIP driving circuit;

[0067] The total number of the touch GIP driving circuits is M, and the M touch GIP driving circuits are connected in a cascaded manner. Combining Figure 5 , for the first row of touch sensors sensor1 and sensor2, they correspond to one touch GIP driving circuit TP_GIP1 and two touch signal switches T1 and T2. The control ends of the two touch signal switches T1 and T2 are both connected to the output end of the touch GIP driving circuit TP_GIP1. Similarly, for the second row of touch sensors sensor3 and sensor4, they correspond to one touch GIP driving circuit TP_GIP2 and two touch signal switches T3 and T4. For the third row of touch sensors sensor5 and sensor6, they correspond to one touch GIP driving circuit TP_GIP3 and two touch signal switches T5 and T6.

[0068] The beneficial effect of this technical solution is to reduce the number of touch GIP driving circuits and save the manufacturing cost; when the touch signal control line RX1 is connected to the touch sensor sensor1, and at the same time 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, and at the same time the touch signal control line RX2 is disconnected from the touch sensor sensor2.

[0069] A display driving method, using the above-mentioned display driving architecture, includes:

[0070] Within the display time of one frame, first all the pixel GIP driving circuits drive the pixel light-emitting units row by row, and then all the 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 simultaneously.

[0071] When the touch signal switches in the same row are in the on state, N touch sensors in the same row are respectively connected to 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 in the same row are in the off state, N touch sensors in the same row are respectively disconnected from N touch signal control lines, so that the touch signal control lines do not receive and process the touch signals of this row.

[0072] For example, the touch sensors are distributed in a three-row and two-column matrix, and the pixel light-emitting units are distributed in a ninety-row and sixty-column matrix. After the pixels of the pixel TFTs of the ninety-row pixel light-emitting units receive the conduction signals from top to bottom in sequence, the touch signal switches corresponding to the three-row touch sensors receive the conduction signals from top to bottom in sequence. The two touch sensors in each row are simultaneously connected to the two touch signal control lines.

[0073] Another embodiment of the present utility model is that the touch GIP driving circuits located in the same row drive the touch signal switches in the same row in sequence. For example, in the first row, the touch signal control line RX1 is first connected to the touch sensor sensor1, and then the touch signal control line RX2 is 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 then the touch signal control line RX2 is 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 then the touch signal control line RX2 is connected to the touch sensor sensor6.

[0074] Further, Q rows of the pixel light-emitting units are provided for one row of the touch sensors, where Q is an integer greater than or equal to two, and the number of rows R of the pixel light-emitting units is Q times the number of rows M of the touch sensors;

[0075] Taking Q rows of the pixel light-emitting units and Q rows of the pixel driving circuits as a group;

[0076] During the display time of one frame, first, when the first group of the pixel GIP driving circuits drive the first group of the pixel light-emitting units row by row, all the touch GIP driving circuits do not work;

[0077] Then, when the Mth group of the pixel GIP driving circuits drive the Mth group of the pixel light-emitting units row by row, the (M - 1)th row of the touch GIP driving circuits drive the (M - 1)th row of the touch signal switches;

[0078] Finally, when all the pixel light-emitting units are driven, the Mth row of the touch GIP driving circuits drive the Mth row of the touch signal switches.

[0079] For example, Q is thirty, R is ninety, and M is three. During the display time of one frame, the thirty pixel GIP driving circuits (GIP1 to GIP30) in the first group drive the thirty pixel light-emitting units in the first group row by row, and the output ends of all the touch GIP driving circuits do not emit conduction signals. Then, the thirty pixel GIP driving circuits (GIP31 to GIP60) in the second group drive the thirty pixel light-emitting units in the second group row by row. At this time, the first row of touch GIP driving circuits (TP_GIP1, TP_GIP2) drive the touch signal switches (T1, T2) in the first row, and the touch signal control lines RX1 and RX2 are respectively connected to the touch sensors sensor1 and sensor2. Then, the thirty pixel GIP driving circuits (GIP61 to GIP90) in the third group drive the thirty pixel light-emitting units in the third group row by row. At this time, the second row of touch GIP driving circuits (TP_GIP3, TP_GIP4) drive the touch signal switches (T3, T4) in the second row, and the touch signal control lines RX1 and RX2 are respectively connected to the touch sensors sensor3 and sensor4. Finally, the output ends of all the pixel GIP driving circuits do not emit conduction signals to the pixel light-emitting units. At this time, the third row of touch GIP driving circuits (TP_GIP5, TP_GIP6) drive the touch signal switches (T5, T6) in the third row, and the touch signal control lines RX1 and RX2 are respectively connected to the touch sensors sensor5 and sensor6.

[0080] The working mode of the present utility model: In combination with Figure 4 , a touch GIP driving circuit (TP_GIP1 to TP_GIP6) is newly added beside the pixel GIP driving circuits (GIP1 to GIP90) on the left side of the original display screen. One touch GIP driving circuit controls one in a row of touch sensors. 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 circuits (TP_GIP1, TP_GIP3, TP_GIP5) output row by row, the touch signal control line RX1 can sequentially control the touch sensors sensor1, sensor3, and sensor5. Similarly, the touch signal control line RX2 sequentially controls the touch sensors sensor2, sensor4, and sensor5. In Figure 4 , there are a total of six touch sensors, and only two touch signal control lines RX1 and RX2 are required; much less than the conventional structure, as Figure 1 shown, the six touch signal control lines (RX1 to RX6) required, significantly reducing the number of touch signal control lines.

[0081] Adopting the display screen driving architecture of the present utility model, the driving timing of the original touch signal control line also needs to be adjusted accordingly, such asFigure 3 As shown, the driving timing of the conventional touch signal control line is that within one frame time, after the pixel display work in the working area of the pixel panel, the signal transmission between the touch signal control line and the touch sensor is carried out. As Figure 6 shown, in the present invention, the driving timing of the touch signal control line is also within one frame time. After the pixel display work in the working area of the pixel panel, since the touch GIP circuit needs to output line by line, the signals of the touch signal control line need to be separately touched line by line, so as to meet the touch timing requirements of the present invention. From the comparison of the driving timings of the new and old touch signal control lines, it can be seen that while reducing the number of touch signal control lines in the present invention, the sensing time for the touch signal control line to connect to the touch sensor will be shortened. For this defect, the driving timing of the dedicated touch signal control line of the present invention can be further developed. As Figure 7 shown, after the output of the GIP30 stage of the pixel GIP driving circuit ends, the touch sensors sensor1 / 2 can start to work until the output of the GIP60 stage of the pixel GIP driving circuit ends, and then the touch sensors sensor1 / 2 stop working and are replaced by the touch sensors sensor3 / 4 to work, and so on. Only the display time of the last row of touch sensors needs to be reserved within one frame, and the remaining touch sensor time can be used as the pixel display working time to maximize the pixel display work.

[0082] Combined with Figure 3 , one frame time is composed of the display time and the touch (RX) time. Combined with Figure 6 , the sensing time of the improved single touch sensor is the touch (sensor1 / 2, sensor3 / 4, sensor5 / 6) time divided by the number of touch GIP driving circuits; combined with Figure 7 , the sensing time of the dedicated single touch sensor is the display time divided by the number of touch GIP driving circuits. Generally, the display time is much longer than the touch (sensor1 / 2, sensor3 / 4, sensor5 / 6) time, so the sensing time of the improved single touch sensor will be much less than that of the dedicated version. Therefore, the driving timing of the dedicated touch signal control line of the present invention can significantly increase the display time and the touch (sensor1 / 2, sensor3 / 4, sensor5 / 6) time compared with the driving timing of the improved touch signal control line of the present invention.

[0083] Although the specific embodiments of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should all be covered by the scope protected by the claims of the present utility model.
