Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should also be noted that for ease of description, only the parts relevant to the application are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
It can be understood that, as shown in the schematic structural diagram of the display panel shown in fig. 1, circuit boards are packaged at two sides of the display panel, the circuit boards are externally connected with processing modules such as a Timing Controller (TCON) and a Digital Voltage Regulator (DVR) to provide data signals for the display panel, and a plurality of rows of pixel arrays are arranged on the display panel and connected with signal lines on the circuit boards.
It can also be understood that due to the capacitive coupling between the signal lines and the gray scale voltage difference between two adjacent pixel array rows, a horizontal Crosstalk picture (H Crosstalk Pattern) may occur on the display panel, that is, a horizontal Crosstalk picture occurs in different gray scale transition regions.
As shown in FIG. 1, if the display panel is 8bit, the horizontal crosstalk image may appear on both sides of the central white frame, such as at the transition from G255 (G63) gray scale to G63 (G255) gray scale, or at the transition from G0 (G63) gray scale to G63 (G0) gray scale. That is, due to the effect of capacitive coupling, the gray scale voltage difference existing at the gray scale change boundary will cause the change of the output value of the common electrode, thereby causing horizontal crosstalk.
In the embodiment of the present application, in order to eliminate the generated horizontal crosstalk, a method as shown in fig. 2 may be combined to analyze a variation of the output value of the corresponding common electrode by detecting a gray-scale voltage difference between two adjacent pixel array rows, so as to compensate the variation according to the analyzed variation, so as to eliminate a fluctuation of the output value of the common electrode, that is, eliminate a horizontal crosstalk image on the display panel.
Fig. 2 is a schematic flowchart of a crosstalk cancellation method provided in an embodiment of the present application, and as shown in fig. 2, the method includes:
s210, detecting data signals of the first row of pixel arrays and data signals of the second row of pixel arrays.
S220, determining the gray scale voltage difference between the first row of pixel array and the second row of pixel array based on the data signals of the two adjacent rows of pixel arrays.
And S230, determining the change amount of the output value of the common electrode based on the gray-scale voltage difference.
And S240, correcting the target output value of the common electrode based on the variation.
Specifically, in order to eliminate the horizontal crosstalk, in the embodiment of the present application, data signals of two adjacent rows of pixel arrays (that is, a first row of pixel arrays and a second row of pixel arrays) on the display device are detected, a difference between a gray scale voltage corresponding to the first row of pixel arrays and a gray scale voltage corresponding to the second row of pixel arrays is analyzed, a variation of an output value of the common electrode is determined according to the difference, and finally, a target output value of the common electrode can be corrected according to the variation to compensate a variation (VCOM Ripple) of the output value of the common electrode caused by the capacitive coupling and the gray scale voltage difference, so as to eliminate the horizontal crosstalk and improve the display effect of the display screen.
In order to better understand the crosstalk cancellation method provided in the embodiment of the present application, the crosstalk cancellation method is described in detail below with reference to fig. 3 and 4, fig. 3 is a schematic flow chart of the crosstalk cancellation method provided in another embodiment of the present application, and fig. 4 is a schematic diagram of gray-scale voltage differences and common electrode output variation in the embodiment of the present application. As shown in fig. 3, the method includes:
s310, detecting the data signals of the first row of pixel arrays and the data signals of the second row of pixel arrays.
Specifically, as shown in the structural diagram of the display panel shown in fig. 1, when the data signal to be displayed is transmitted to a processor, such as binary data input by a Time Controller (TCON), the TCON can detect the input binary data signal.
S321, determining gray scale voltage values of the data signals of the first row of pixel arrays and the data signals of the second row of pixel arrays on each data line.
S322, determining a gray scale voltage difference between the first row of pixel arrays and the second row of pixel arrays on each data line based on the gray scale voltage value.
Specifically, after binary data signals of two adjacent rows of pixel arrays on each data line are detected, the difference between the gray scale voltages of the two adjacent rows of pixel arrays can be calculated through the corresponding gray scale voltage values. That is, the detected binary data signal corresponds to a gray scale level, which corresponds to a corresponding gray scale voltage, i.e., a driving voltage.
For example, taking an 8-bit display panel as an example, 256 gray scales (0-255) are provided, G0 represents black, G255 represents white, and G63 represents an intermediate gray scale; and the gray scale voltage corresponding to G255 is represented as V1 (positive voltage) and V18 (negative voltage); the gray scale voltages corresponding to G63 are V6 (positive voltage) and V13 (negative voltage). That is, the gray-scale voltages detected are V1, V6, V13, and V18, respectively.
It can be understood that for the 8-bit display screen in the above example, the horizontal Crosstalk picture (H Crosstalk Pattern) usually appears at the transition from the G255 gray scale to the G63 gray scale, or at the transition from the G63 gray scale to the G255 gray scale; or the transition part from the G0 gray scale to the G63 gray scale; or G63 gray level to G0 gray level transition.
Further, for the above example, as shown in fig. 4 and fig. 1, when the gray scale G255 of the first row pixel array on the positive polarity data line (Source line a) changes to the gray scale G63 of the second row pixel array, the gray scale voltage corresponding to the data line changes from V1 to V6, and the gray scale voltage on the negative polarity data line changes from V18 to V13, thereby generating the gray scale voltage difference. Similarly, when the gray scale G63 of the first row of pixel arrays on the positive polarity data line changes to the gray scale G255 of the second row of pixel arrays, the gray scale voltage corresponding to the data line changes from V6 to V1, and the gray scale voltage corresponding to the negative polarity data line changes from V13 to V18, thereby generating a gray scale voltage difference between the adjacent rows of pixel arrays.
And S230, determining the change quantity of the output value of the common electrode based on the gray scale voltage change value and a preset comparison table.
Specifically, the VCOM Ripple corresponding to the gray scale voltage difference of the current data signal on each data line may be searched from the comparison table between the pre-established gray scale voltage difference and the variation (VCOM Ripple) of the common electrode output value according to the obtained gray scale voltage difference of the adjacent pixel array row.
It can be understood that, the crosstalk cancellation method provided in the embodiment of the present application may generate a comparison table in advance. For example, a table of gray level voltage differences and VCOM Ripple can be generated by sequentially detecting and recording VCOM Ripple caused by each gray level voltage difference through simulation experiments and the like. I.e., the amount of change corresponding to each data line.
For example, taking the above gray scale voltage values and the obtained gray scale voltage differences as examples, the lookup table can determine that VCOM Ripple of two adjacent rows of pixel arrays on a positive polarity data line from V1 to V6 is-a Δ V1, VCOM Ripple of n negative polarity data lines caused by the change of gray scale voltage from V18 to V13 is n Δ V2, VCOM Ripple of m data lines caused by the change of gray scale voltage from V6 to V1 is m Δ V1, and VCOM Ripple of b negative polarity data lines caused by the change of V13 to V18 is-b Δ V2.
Then based on the above variation and the total amount of data lines, the total VCOM Ripple caused by the gray scale voltage difference can be calculated as:
(m-a)△V1+(n-b)△V2
and S340, correcting the target output value of the common electrode based on the variation.
Specifically, after the total variation of the common electrode output Value (VCOM) caused by the gray-scale voltage difference of the pixel arrays in the adjacent rows is obtained through search and calculation, the amount of adjustment of the common electrode output value, that is, the total variation of VCOM, may be determined according to the total variation:
-(m-a)△V1-(n-b)△V2
further, the target output value of the common electrode may be determined according to the total variation of VCOM:
V-(m-a)△V1-(n-b)△V2
for example, the TCON may be utilized to send the adjusted target output value to the DVR via an interface (e.g., I2C) to cause the DVR to generate the adjusted common electrode output value.
According to the crosstalk elimination method provided by the embodiment of the application, the gray-scale voltage difference between the adjacent pixel array rows is obtained through analysis by detecting the data signals of the two adjacent pixel array rows on the display device, and the output value variable quantity of the corresponding public electrode is searched from the pre-established comparison table according to the gray-scale voltage difference, so that the target output value of the public electrode can be adjusted by utilizing the variable quantity, the floating of the voltage of the public electrode caused by the gray-scale voltage difference is compensated, the influence of the gray-scale voltage change caused by capacitive coupling on the output of the public electrode is reduced, the horizontal crosstalk is eliminated, and the display quality is improved.
