detailed description

In the digital drive scanning algorithm in the related art, the scanning time of each row of pixels is related to the number of rows of the display panel. Therefore, for a display panel with a large number of rows, the scanning time of each row of pixels is very short, resulting in a relatively short display effect. Bad situation. According to the applicant’s research, it is found that the digital drive scanning algorithm usually adopts a progressive scan method, after scanning one row of sub-pixels, then scanning the next row of sub-pixels. For example, for the sub-field scanning method, a frame is usually divided into multiple sub-frames. In each sub-frame, all sub-pixels in the display panel are scanned row by row. Therefore, the time to scan each row of sub-pixels is very short. When scanning sub-pixels, the corresponding data voltages are usually written into the sub-pixels, so that the time for writing the data voltages into the sub-pixels is very short, resulting in insufficient data voltage writing time, making the data voltage unable to be written The input completely causes the grayscale display to be abnormal, and the display effect is poor.

An embodiment of the present application provides a digital driving method for a display panel. FIG. 1 is a schematic structural diagram of a display panel provided by an embodiment of the present application, and FIG. 2 is a digital driving method for a display panel provided by an embodiment of the present application. A flowchart of the method. FIG. 3 is a working timing diagram of a display panel digital drive provided by an embodiment of the present application. Referring to FIG. 1, FIG. 2 and FIG. 3, the display panel includes sub-pixels 110 arranged in an array of m rows and n columns. , Multiple scan lines (S1, S2, S3, S4...) and multiple data lines (D1, D2, D3, D4...), each scan line is connected to a row of sub-pixels, and each data line is connected to a column of sub-pixels , Where m and n are both integers greater than or equal to 1, and the digital driving method of the display panel includes step 210 to step 220.

In step 210, a scan pulse signal is simultaneously provided to a plurality of scan lines, and a first data voltage is simultaneously provided to a plurality of data lines.

1, the display panel may further include a scan driving circuit 120, a data driving circuit 130, a data processor 140, and a timing controller 150. The displayed data stream enters the data processor 140, and the timing controller 150 controls the driving timing of the scan driving circuit 120 and the data driving circuit 130 respectively. Exemplarily, when the display panel is driven by the digital driving method, the data voltage provided to the data line usually only includes the black state data voltage and the bright state data voltage, and the black state data voltage and the bright state data voltage may be fixed values. In the digital driving method of the display panel, one frame of display screen can be divided into multiple sub-frames. Fig. 3 schematically shows the driving sequence in two sub-frames. Referring to Fig. 3, each sub-frame may include data In the writing phase t1 and the driving light-emitting phase t2, in different sub-frames in one frame, the time length of the driving light-emitting phase t2 may be different. For example, when one frame is divided into four sub-frames, the driving light-emitting phase of the four sub-frames The time ratio can be 1:2:4:8. Wherein, in a sub-frame, when the sub-pixel 110 is finally written with a black data voltage in the data writing stage, the sub-pixel 110 does not emit light during the driving and light-emitting stage of the sub-frame; in one sub-frame, the sub-pixel 110 In the case where the bright data voltage is finally written into the data writing stage 110, the sub-pixel 110 emits light in the driving light-emitting stage of the sub-frame. The sub-pixel 110 is controlled to emit light in different sub-frames. The light-emitting duration in the frame (that is, by controlling the input of different data voltages to the sub-pixels 110 in different sub-frames), the display of different gray levels is realized. Wherein, the first data voltage may be a black state data voltage or a bright state data voltage.

The scan pulse signal can be used to control the writing of the data voltage. FIG. 4 is a schematic structural diagram of a digital driving pixel circuit provided by an embodiment of the present application. Referring to FIG. 4, the digital driving pixel circuit includes a first transistor T1 and a second transistor. Transistor T2, third transistor T3, storage capacitor Cst, data voltage input terminal Vdata, light emitting device D5, scan signal input terminal Scan and light emission control signal input terminal EM, first power supply voltage input terminal VDD, and second power supply voltage input terminal VSS . Among them, the scan signal input terminal Scan can be connected to a scan line, and the data voltage input terminal Vdata can be connected to a data line. 4, the scan pulse signal is used to control the conduction of the first transistor T1, so that when the first transistor T1 is turned on, the data voltage on the data line can be written to the gate of the second transistor T2 through the first transistor T1. The second transistor T2 serves as the driving transistor of the pixel circuit. It should be noted that the digital driving method provided in this embodiment is not only applicable to the display panel including the pixel circuit shown in FIG. 4, and the display panel of the pixel circuit shown in FIG. 4 is only used to illustrate that the scan pulse signal can be used to control whether the data voltage It can be written into the sub-pixel 110.

After the scan pulse signal is provided to the scan line, the data voltage can be written into the sub-pixel 110 that is electrically connected to the scan line; if the scan pulse signal is not provided to the scan line, the sub-pixel that is electrically connected to the scan line cannot be provided. The data voltage is written in the pixel 110. Exemplarily, referring to FIG. 3, the full-screen data signal Data includes two voltages, where the low level may represent the first data voltage. In this step, multiple scan lines are provided with scan pulse signals at the same time, that is, all rows of pixels in the display panel are scanned at the same time, and the first data voltage is provided to the data lines at the same time, so that each sub-pixel 110 in the display panel is simultaneously Write the first data voltage. Among them, Scan1, Scan2, Scan3, Scan4, Scan5, Scan6, Scan7...Scanm in Figure 3 can respectively represent the scan signals input to the first, second, third, fourth, fifth, sixth, seventh...m rows of sub-pixels. Referring to FIG. 3, the scan pulse signal may be a low-level pulse signal, and step 210 in FIG. 2 corresponds to the stage indicated by t11 in the figure. At this stage, all rows of sub-pixels 110 are scanned simultaneously, and the first data voltage is completed. Write.

In step 220, the second data voltage is provided to a plurality of data lines one by one. During the period when the second data voltage is provided to one data line, a scan pulse signal is simultaneously provided to the scan lines connected to the sub-pixels that need to write the second data voltage. .

Exemplarily, in a sub-frame, the data voltages that need to be written to different sub-pixels 110 may be different. Therefore, after the first data voltage is written to the sub-pixels 110 in step 210, it is necessary to correspond to the data in the display panel. The sub-pixel 110 of the second data voltage re-writes the data voltage. The writing method may be to write the second data voltage to the sub-pixels 110 corresponding to the second data voltage in the display panel column by column. When the second data voltage is written, the second data voltage is provided to a plurality of data lines one by one, and during the period when the second data voltage is provided to one data line, the scanning is connected to the sub-pixel 110 that needs to write the second data voltage. The line provides scan pulse signals at the same time, so that among the sub-pixels 110 that are electrically connected to the data line, the sub-pixels 110 that need to write the second data voltage are turned on to ensure that the data voltage can be written in, but not The scan line connected to the sub-pixel 110 of the first data voltage provides a scan pulse signal, so that the sub-pixel 110 that needs to write the first data voltage maintains the first data voltage that has been written in step 210. Referring to FIGS. 2 and 3, step 220 in FIG. 2 may correspond to the stage corresponding to t12 in FIG. 3. Referring to FIGS. 1 and 3, the first three columns of sub-pixels 110 in the display panel are taken as an example for description. In one column of sub-pixels 110, there is no sub-pixel 110 that needs to write the second data voltage. In the second column of sub-pixels 110, the sub-pixels 110 in the first row, third row, and seventh row need to write the second data voltage. The sub-pixels 110 located in the first row, second row, fourth row, and m-th row of the column sub-pixels 110 need to write the second data voltage; then, the first column sub-pixel r1 that is electrically connected to the first data line D1 When the second data voltage is provided, no scan pulse signal is provided to the multiple scan lines; when the second data voltage is provided to the second column sub-pixel r2 electrically connected to the second data line D2, The scan lines electrically connected to the sub-pixels 110 in the three rows and the seventh row provide scan pulse signals at the same time, and the second data voltage is written into the sub-pixels 110 in the first, third, and seventh rows in the second column of sub-pixels 110 ; When the second data voltage is provided to the third column of sub-pixels r3 electrically connected to the third data line D3, to the scan lines electrically connected to the first row, second row, fourth row, and m-th row sub-pixels 110 A scan pulse signal is provided, and the second data voltage is written into the sub-pixels 110 in the first row, the second row, the fourth row, and the m-th row in the second column of sub-pixels 110. In this step, the method of scanning the sub-pixels 110 line by line (after scanning one line of sub-pixels 110, scanning the next line of sub-pixels 110) is not adopted, but during the period when the second data voltage is provided to one data line, The rows of the sub-pixels 110 that need to write the second data voltage among the sub-pixels 110 electrically connected to the data line are scanned at the same time. Therefore, the scanning time for each row of the sub-pixels 110 is independent of the number of rows of the sub-pixels 110 in the display panel. It is related to the number of columns of sub-pixels 110 in the display panel and the number of sub-pixels 110 corresponding to the second data voltage in each row of sub-pixels 110. Since the scan time of each row of sub-pixels 110 has nothing to do with the number of rows of sub-pixels 110, there will be no case that the scan time of each row of sub-pixels 110 is too short due to the large number of rows of sub-pixels 110 in the display panel. The display abnormality caused by the short scanning time of each row of sub-pixels 110 caused by the excessive number of rows of the display panel in the technology.

The digital driving method of the display panel provided by the embodiments of the present application provides scan pulse signals to multiple scan lines at the same time, and provides first data voltages to multiple data lines simultaneously; and provides second data to the multiple data lines one by one. During the period when the second data voltage is provided to one data line, a scan pulse signal is simultaneously provided to the scan line connected to the sub-pixels to which the second data voltage needs to be written, so that the The scanning time has nothing to do with the number of rows of sub-pixels in the display panel, so as to avoid display abnormalities caused by the short scanning time of each row of sub-pixels caused by the excessive number of rows of the display panel in the related art.

In one embodiment, m>n+1.

The display panel in the related art, especially a mobile phone, is usually a vertical display panel, and the number m of rows of sub-pixels 110 in the vertical display panel is generally much larger than the number of columns n of sub-pixels 110. In a portrait display panel, too many rows of 110 sub-pixels cause display abnormalities, which is particularly serious. In the embodiment of the present application, by simultaneously providing scan pulse signals to multiple scan lines and simultaneously providing the first data voltage to multiple data lines, the first data voltage is written into all sub-pixels 110 in all display panels at the same time; By providing the second data voltage to a plurality of data lines one by one, during the period when the second data voltage is provided to one data line, the scan pulse signal is simultaneously provided to the scan line connected to the sub-pixel 110 that needs to write the second data voltage, which can extend The data voltage writing time to each sub-pixel 110. Exemplarily, in one sub-frame, the total scanning time of all sub-pixels 110 in the display panel is T. When the traditional scanning method is adopted, the scanning time of each row of sub-pixels 110 (the time corresponding to the width of each scanning pulse signal ) Is T/m, and when the traditional scanning algorithm is used, the data voltage of a row of sub-pixels 110 is usually written at the same time, and the time for each sub-pixel 110 to write the data voltage is T/m. When the digital drive scanning algorithm provided by the embodiment of this application is used, the time corresponding to the width of each scan pulse signal is T/n+1, and the time corresponding to the width of each scan pulse signal is equal to the writing data voltage of one sub-pixel 110 time. Since m>n+1, then T/m<T/n+1, the digital driving method provided in this embodiment can widen the width of a single scan pulse signal. Correspondingly, the scanning of each row of sub-pixels 110 The longer the time, the longer the time for writing the data voltage in the sub-pixel 110, and the data voltage corresponding to the sub-pixel 110 can be fully written, so that each sub-pixel 110 can display the gray scale normally and improve the display effect.

In one embodiment, the first data voltage is a bright data voltage, and the second data voltage is a black data voltage.

As described above, in the digital driving method, the data voltage written into the sub-pixel 110 usually only includes the bright state data voltage and the black state data voltage. Provide scan pulse signals to multiple scan lines at the same time, and provide bright data voltages to multiple data lines at the same time, so that all sub-pixels 110 in the display panel are initially written with the bright data voltages, and some sub-pixels 110 correspond to When the data voltage is the black state data voltage, the black state data voltage is provided to the data lines one by one, and during the period when the black state data voltage is provided to a data line, the sub-pixel 110 electrically connected to the data line needs to be written The row of the sub-pixel 110 of the black state data voltage can be scanned; thus, the scanning time of each row is independent of the number of rows of the sub-pixels 110 in the display panel, and the scanning of each row of the sub-pixels 110 caused by too many rows of the display panel can be avoided. Abnormal display caused by short time.

In one embodiment, the first data voltage is a black data voltage, and the second data voltage is a light data voltage.

Exemplarily, scan pulse signals are provided to multiple scan lines at the same time, and bright data voltages are provided to multiple data lines at the same time, so that all sub-pixels 110 in the display panel are initially written with black data voltages. When the data voltage corresponding to the sub-pixel 110 is the bright-state data voltage, the bright-state data voltage is provided to the data lines one by one, and during the period when the black-state data voltage is provided to one data line, the sub-pixel 110 electrically connected to the data line It is sufficient to scan the row of the sub-pixel 110 where the bright-state data voltage needs to be written; thus, the scanning time of each row is independent of the number of rows of the sub-pixels 110 in the display panel, so as to avoid each row of sub-pixels caused by too many rows in the display panel. The display is abnormal due to the short scanning time of the pixel 110.

FIG. 5 is a flowchart of another digital driving method for a display panel provided by an embodiment of the present application. Referring to FIG. 5, the digital driving method includes steps 310 to 320.

Exemplarily, the beginning stage of each sub-frame may be the moment when each sub-frame is entered; that is, after entering a sub-frame, the scan pulse signal is provided to multiple scan lines at the same time, and the first data voltage is provided to the data line at the same time Therefore, the time of each sub-frame can be fully utilized, so that the subsequent writing of the second data voltage can also have sufficient time, so that the data voltage can be fully written into the sub-pixel 110 to ensure a good display effect.

In step 320, the second data voltage is provided to the plurality of data lines one by one, and during the period when the second data voltage is provided to one data line, a scan pulse signal is simultaneously provided to the scan line connected to the sub-pixel that needs to write the second data voltage. .

In an embodiment, each sub-pixel 110 includes a digital driving pixel circuit.

In step 520, the second data voltage is provided to a plurality of data lines one by one. During the period when the second data voltage is provided to one data line, a scan pulse signal is simultaneously provided to the scan line connected to the sub-pixel to which the second data voltage needs to be written. In any sub-frame, when the second data voltage is provided to the multiple data lines one by one, the light-emitting control module in the digital driving pixel circuit of each sub-pixel is controlled to turn off;

In step 530, after the second data voltage is provided to all the data lines, the light emitting control module in the digital driving pixel circuit of each sub-pixel is controlled to be turned on.

3 and 4, taking the third transistor T3 as a P-type transistor as an example, when the second data voltage is provided to a plurality of data lines one by one, the light emission control signal input terminal EM inputs a high level to control the power of each sub-pixel 110 The light-emitting control module in the digital drive pixel circuit is turned off, which can ensure that the sub-pixel 110 does not emit light when the second data voltage is written to the sub-pixel 110. After the second data voltage is provided to all data lines, the light-emitting control signal input terminal EM inputs a low level to control the light emission control module in the digital drive pixel circuit of each sub-pixel 110 to turn on, so that after the data voltage corresponding to the sub-pixel 110 in the display panel is written, the full-screen sub-pixel 110 corresponds to the bright state The sub-pixels 110 of the data voltage emit light together, thereby facilitating the control of the light-emitting time of the sub-pixels 110 in the sub-frame, thereby ensuring the normal display of gray scales, and improving the display effect.

It should be noted that when the scan pulse signal is provided to multiple scan lines at the same time, and the first data voltage is provided to multiple data lines at the same time, the light emitting control module can also be controlled to be turned off to avoid light emission when writing the first data voltage.

Exemplarily, in any sub-frame, the number of scan pulse signals output to a scan line is determined by the number of sub-pixels 110 to which the second data voltage needs to be written in the row of sub-pixels 110 electrically connected to the scan line . In any sub-frame, if the signal output to at least one scan line includes at least two scan pulse signals, the second data voltage can be written to two sub-pixels 110 in at least one row of sub-pixels 110. In addition, the signal output to at least one scan line includes at least two scan pulse signals, so that the scan time for a row of sub-pixels 110 is relatively longer, which is more conducive to the full writing of the second data voltage and ensures a good display effect.

3, in an embodiment, the digital driving method includes a first stage t11 and a second stage t12;

In a sub-frame, the data voltages corresponding to the sub-pixels in different rows in the same column may all be the second data voltage. In this case, it is necessary to provide scan pulses to the sub-pixels in the same column corresponding to the second data voltage. Signal, the scan pulse signals provided to the at least two scan lines overlap, thereby ensuring the normal writing of the second data voltage to the at least two sub-pixels 110 in the same column and ensuring the display effect.

Referring to FIG. 3, in one embodiment, in the second stage t12, the scan pulse signals provided to the scan lines include scan pulse signals with different pulse widths.

Exemplarily, in some display screens, the data voltages corresponding to sub-pixels in adjacent columns in the same row may all be the second data voltages.
