In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. It is to be understood that the described embodiments are merely exemplary of a portion of the invention and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without inventive step, shall fall within the scope of protection of the present invention.
It should be noted that the terms "first," "second," and the like in the description, the claims, and the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
First, please refer to fig. 2 for better explaining the inventive concept of the present application, and fig. 2 is a scan timing diagram of an in-cell touch panel according to an embodiment of the present invention. The embedded Touch panel of this embodiment employs a TDDI LHB (Touch and Display Driver Integration) Touch mode, in which the LHB mode scanning mode is performed in a Touch and Display time-sharing manner, and a Touch stage is inserted in a Display process at intervals in segments, that is, a part of Touch scanning is inserted after a certain number of lines are scanned in a Display process, and such an alternate scanning manner is performed. As shown in fig. 2, in one display frame period, a multi-line display scan is performed per display stage. Including but not limited to the same number of rows per scan. For example, in fig. 2, a touch scan (TP period) is inserted after each scan of 4 rows of display lines. That is, when a display period (display period) starts, the Gate lines Gate1-Gate4 sequentially scan, a plurality of Gate lines are used to sequentially Gate the pixel units in the corresponding row, the source driver transmits corresponding gray scale voltages through the source data lines (the gray scale voltages are processed after the source driver receives the source data to obtain corresponding gray scale voltages), when the Gate lines Gate4 finishes scanning, touch starts scanning (i.e., touch detection is realized), and the Gate lines stop scanning. After the scanning of the touch control is finished, the 5 th row (Gate5) is displayed, namely, the Gate line Gate5 is scanned, and then a display stage is started, namely, the Gate lines Gate5-Gate8 are scanned in sequence, pixel units of the corresponding row are gated, gray scale voltages are transmitted by source lines, when the scanning of the Gate line Gate8 is finished, the touch control starts to scan again, the Gate lines stop scanning, the process is circulated, the scanning of every four Gate lines is taken as a display stage, and in each display frame period, the display stage and the touch control stage are alternately performed. In the scanning mode, the touch scanning is interrupted in the normal display process, the level on the source line is changed during the touch scanning, the level on the common electrode is also changed, and when the scanning signal is output again, the ramp time of the process voltage during the period can also cause insufficient charging, and possibly influence a plurality of display lines after the scanning is restarted, so that the display abnormality occurs on the display lines immediately after the touch scanning is finished. And due to the insertion of the touch stage, display abnormalities caused by leakage of some display lines before the touch stage starts may also occur, so the cross striation phenomenon may occur in the display line immediately after the touch scanning, including but not limited to the line closest to the front and back of the touch stage, such as the 4 th line, the 5 th line, and the 8 th line in fig. 2.
Therefore, the present invention is conceived to solve the problems of the display horizontal stripes caused by the leakage of the display lines before the touch stage and/or the insufficient charging of the display lines after the touch stage during the display due to the in-cell touch panel alternately performing the display stage and the touch stage at different times, and thus the display panel can be driven by higher gray scale voltages by modifying the gray scales of the related display lines, for example, increasing the gray scales of the related display lines before and after the touch stage, so as to solve the problems of the leakage of the display lines before the touch stage and/or the insufficient charging of the display lines after the touch stage.
To solve the above technical problems, embodiments of the present invention provide a source data generating method, a timing controller, a display device and a storage medium. First, a method for generating source data according to an embodiment of the present invention will be described.
Referring to fig. 3, fig. 3 is a flow chart illustrating a source data generating method according to an embodiment of the invention. In this embodiment, the source data generation method is applied to a timing controller, the timing controller is connected to an in-cell touch panel, the in-cell touch panel includes a display stage and a touch stage within a display frame, and the display stage and the touch stage are alternately performed at different times. Accordingly, as shown in fig. 3, the method for generating source data according to the embodiment of the present invention includes:
step S101, performing gray scale compensation on source data corresponding to pixel units of a display line, where the display line includes at least one display line before and/or after the touch stage starts and/or ends.
Specifically, the source data is substantially a gray scale voltage applied to the pixel unit by the source driver through the source data line. Due to the problem of charging time, the voltage signal loaded in the pixel unit cannot reach the gray scale which is originally supposed to be displayed, and due to the insertion of the touch stage, at least one display line before the touch stage has electric leakage, so that normal display cannot be performed, and cross striations occur. Therefore, the source data generating method provided in this embodiment alternately performs the in-cell touch panel in the display phase and the touch phase in a time-sharing manner, and performs the gray scale compensation on the source data corresponding to the pixel units of at least one display line before and/or after the touch phase, which essentially adopts an overdrive solution logic. For example, in the scanning method shown in fig. 2, if a frame is a frame with the same gray level, for example, the gray level of each row is 127 gray levels, and at this time, the source data is not adjusted, that is, the gray level voltage loaded on the panel is not corrected, the cross striation phenomenon occurs in the rows before and after the touch stage (for example, Gate4 and Gate5, Gate8 and Gate 9), according to the scheme of the present embodiment, the source data of the display rows such as Gate4 and Gate5, Gate8 and Gate9 are compensated to 128 gray levels, that is, 1 gray level is added to the original gray level, so that the cross striation phenomenon can be better improved, and the compensation of the gray levels includes but is not limited to increasing 1 gray level, and also includes but is not limited to increasing one row before and after the touch stage.
It should be noted that gray scale compensation is performed on the source data corresponding to the pixel units of at least one display line before and/or after the touch stage, and the gray scale level is not necessarily increased, and may also be decreased according to the actual application scenario, i.e. the display panels with different characteristics.
In one embodiment, the at least one display line before the touch phase starts and/or after the touch phase ends includes a last line before the touch phase starts and/or a first line after the touch phase ends.
Specifically, as shown in fig. 2, the at least one display line before the touch phase starts and/or after the touch phase ends includes the last line before the touch phase starts and/or the first line after the touch phase ends, that is, the last line before the touch phase starts is a display line such as Gate4 or Gate8, and the first line after the touch phase ends is a display line such as Gate5 or Gate 9. Of course, the case where the number of lines per scan is the same is exemplified here, and thus the cycle is regularly made.
It should be noted that the scanning timing of the gate driver is preset according to the specific display panel, so that the specific display lines of at least one display line before and/or after the touch stage is started can be determined by reading the preset scanning timing.
In one embodiment, the step S101 of performing gray scale compensation on the source data corresponding to the pixel units in the display row includes:
and performing gray scale compensation on source electrode data corresponding to the pixel units of the display row according to a preset compensation voltage value to increase a preset gray scale level, wherein the preset compensation voltage value is greater than 0.
Specifically, the voltage difference between different adjacent gray scales is the same, for example, Δ V, so that one gray scale difference is Δ V, two gray scale differences are 2 Δ V, and N gray scale differences are N Δ V, so that when gray scale compensation is performed on the source data, the voltage value of N Δ V can be increased to the original source data according to the preset compensation voltage value Δ V and the gray scale number to be increased, i.e., the preset gray scale number N, and Δ V is greater than 0.
In one embodiment, the at least one display line before the start and/or after the end of the touch phase includes the last line before the start of the touch phase and/or a plurality of lines in sequence after the end of the touch phase.
Specifically, since different display panels have different characteristics, when the gate scanning is performed again, there is insufficient charging of the display rows, and certainly, the insufficient charging phenomenon is weakened in sequence, so that the gray scale compensation of the source data needs to be performed on the display rows in sequence after the touch stage is finished.
In one embodiment, when the display line includes a plurality of lines in sequence after the touch stage is finished, performing gray scale compensation on source data corresponding to pixel units of the display line, including:
and performing gray scale compensation on source electrode data corresponding to the pixel units of the multiple rows in sequence after the touch control stage is finished according to a preset compensation voltage value so as to respectively increase different preset gray scale levels, wherein the preset compensation voltage value is greater than 0, and the increased preset gray scale levels are sequentially decreased progressively.
Specifically, as described in the foregoing embodiments, since different display panels have different characteristics, when the gate scanning is performed again, there is insufficient charging of the plurality of rows of display lines, and the phenomenon of insufficient charging is sequentially reduced. For example, in one display frame period, each display stage performs 8 lines of display scanning, namely, Gate1-Gate8 before the first touch stage and Gate9-Gate16 after the first touch stage, if the scanning is restarted, the 3 lines of display lines, namely, Gate9, Gate10 and Gate11, are affected, and it is easy to know that the problem of insufficient charging of the three lines is sequentially decreased. Therefore, when gray scale compensation is performed on the source data corresponding to the corresponding row, the compensated gray scale levels are sequentially decreased, for example, 3-level gray scale is added to Gate9, 2-level gray scale is added to Gate10, and 1-level gray scale is added to Gate11, so that the cross striation phenomenon caused by insufficient charging is solved.
Step S102, the source data after the gray scale compensation is provided to the source driver to drive the in-cell touch panel for displaying.
Specifically, the source data after the gray scale compensation is provided to the source driver, and the source driver drives the pixel unit of the in-cell touch panel to display through the corresponding gray scale voltage.
Therefore, the source data generating method provided by the embodiment of the invention includes performing gray scale compensation on source data corresponding to pixel units of a display line, and providing the source data subjected to the gray scale compensation to a source driver to drive the in-cell touch panel to display, wherein the display line includes at least one display line before and/or after the touch stage starts and/or ends. According to the invention, gray scale compensation is carried out on the source data corresponding to the pixel units of the display lines before and after the touch control stage, so that the problem of display cross striations caused by electric leakage of the display lines before the touch control stage and/or insufficient charging of the display lines after the touch control stage during display of the embedded touch panel alternately carried out in the display stage and the touch control stage in a time-sharing manner can be solved.
