The technical solution of the present application will be described below with reference to specific examples.
Referring to fig. 1, the display panel 100 includes a display region and a non-display region located at a periphery of the display region. A plurality of sub-pixels arranged in a matrix are disposed in the display area, and the plurality of sub-pixels are divided into a plurality of repeated sub-regions 200 arranged along the row direction or/and the column direction. This embodiment will be described by taking the repetitive sub-area 200 of 4X8 as an example.
In this embodiment, the repeated sub-area 200 includes two first areas 10, and any one of the first areas 10 may include a plurality of sub-pixels arranged in a 4X4 matrix.
In the present embodiment, the sub-pixels in the repeated sub-region 200 are arranged in the form of RGB or BGR. The sub-pixels in the same column are the same color, i.e. the sub-pixels are arranged in a standard RGB arrangement.
In the present embodiment, the first row of sub-pixels 201 and the second row of sub-pixels 202 in the repeated sub-area 200 are controlled by the first scan line 21 to input corresponding scan signals, and the third row of sub-pixels 203 and the fourth row of sub-pixels 204 in the repeated sub-area 200 are controlled by the second scan line 22 to input corresponding scan signals. In the embodiment, two rows of sub-pixels are simultaneously opened through one scanning line, so that the charging time of any sub-pixel is reduced, and the refresh rate is accelerated.
In this embodiment, the first region 10 corresponds to 8 data lines. The sub-pixels of any column are subjected to data input by two different data lines so as to provide different brightness signals and polarity control signals.
The display panel 100 includes a plurality of pixel units 11 repeatedly arranged along rows and columns. Two sub-pixels with the same color are arranged in one pixel unit 11. The sub-pixels in the same pixel unit 11 are input with the same polarity control and different brightness signals from the same data line.
Referring to fig. 1 to 3, the first row of sub-pixels and the third row of sub-pixels are connected to the corresponding data lines in the same manner, and the second row of sub-pixels and the fourth row of sub-pixels are connected to the corresponding data lines in the same manner. And the connection mode of the first column of sub-pixels or/and the third column of sub-pixels and the corresponding data lines is opposite to the connection mode of the second column of sub-pixels or/and the fourth column of sub-pixels and the corresponding data lines.
For example, a first data line 31 connects the first and fourth sub-pixels of the first column in the first area 10, and a second data line 32 connects the second and third sub-pixels of the first column in the first area 10. The third data line connects the second and third sub-pixels in the second row in the first area 10, and the fourth data line connects the first and fourth sub-pixels in the second row in the first area 10. Similarly, a fifth data line connects the first and fourth sub-pixels of the third row in the first area 10, and a sixth data line connects the second and third sub-pixels of the third row in the first area 10. The seventh data line connects the second and third sub-pixels of the fourth column in the first area 10, and the eighth data line connects the first and fourth sub-pixels of the fourth column in the first area 10.
Referring to fig. 2, in a first frame, the polarities of the first row of sub-pixels 201 in the first area 10 are positive, negative, and positive, and the gray-scale signals of the first row of sub-pixels 201 are high gray-scale, low gray-scale, high gray-scale, and low gray-scale. The polarity of the second row of sub-pixels 202 is negative, positive, negative, and the gray scale signals of the second row of sub-pixels 202 are low gray scale, high gray scale, low gray scale, and high gray scale. The polarity of the third row of sub-pixels 203 is negative, positive, negative, and the gray scale signals of the third row of sub-pixels 203 are high gray scale, low gray scale, high gray scale, and low gray scale. The polarity of the fourth row sub-pixel 204 is positive polarity, negative polarity, positive polarity, and the gray scale signal of the fourth row sub-pixel 204 is low gray scale, high gray scale, low gray scale, and high gray scale.
In addition, the polarity of the data lines in the first area 10 is positive, negative, positive, and positive. For example, the first data line 31 is connected to the first and fourth sub-pixels in the first column of sub-pixels 41 to output the corresponding luminance signal and the polarity control signal. The first data line 31 has positive polarity, and the first and fourth sub-pixels have positive polarity. The second data line 32 adjacent to the first data line 31 is connected to the second and third sub-pixels in the first column of sub-pixels 41 to output corresponding luminance signals and polarity control signals. The second data line 32 has a negative polarity, and the second and third sub-pixels have negative polarities. Therefore, in the first frame, the polarities of the sub-pixels 41 in the first column in the first area 10 are positive, negative, and positive. Similarly, the polarities of the other columns of sub-pixels in the first area 10 are similar to the polarities of the first column of sub-pixels 41.
Referring to fig. 3, in the second frame, the polarities of the first row of sub-pixels 201 in the first area 10 are negative, positive, and negative, and the gray-scale signals of the first row of sub-pixels 201 are low gray-scale, high gray-scale, low gray-scale, and high gray-scale. The polarity of the second row of sub-pixels 202 is positive polarity, negative polarity, positive polarity, and the gray scale signals of the second row of sub-pixels 202 are high gray scale, low gray scale, high gray scale, and low gray scale. The polarity of the third row of sub-pixels 203 is positive polarity, negative polarity, positive polarity, and the gray scale signals of the third row of sub-pixels 203 are low gray scale, high gray scale, low gray scale, and high gray scale. The polarity of the fourth row sub-pixel 204 is negative polarity, positive polarity, and negative polarity, and the gray scale signal of the fourth row sub-pixel 204 is high gray scale, low gray scale, high gray scale, and low gray scale.
The polarity of the data lines in the first region 10 is negative, positive, negative. For example, the first data line 31 is connected to the first and fourth sub-pixels in the first column of sub-pixels 41 to output the corresponding luminance signal and the polarity control signal. If the first data line 31 has a negative polarity, the first and fourth sub-pixels have negative polarities. The second data line 32 is connected to the second and third sub-pixels in the first column of sub-pixels 41 to output the corresponding luminance signal and the polarity control signal. The second data line 32 has positive polarity, and the second and third sub-pixels have positive polarity. Therefore, in the second frame, the polarities of the sub-pixels 41 in the first column in the first area 10 are negative, positive, and negative. Similarly, the polarities of the other columns of sub-pixels in the first area 10 are similar to the polarities of the first column of sub-pixels 41.
In the row direction of the first area 10, the polarities of the sub-pixels (for example, in the first frame) are cyclically set to positive polarity, negative polarity, and positive polarity. In the column direction of the first area 10, the polarities of the sub-pixels (for example, in the first frame) are cyclically set to positive, negative, and positive. The above arrangement eliminates the polarity between the sub-pixel deflections, avoids the crosstalk of the display screen, and improves the display effect of the display panel 100.
When the display panel 100 displays the third frame and above, the polarity and gray scale of the corresponding sub-pixels are the same as or similar to those of the first frame and the second frame, and the description thereof is omitted.
On the basis of the display panel 100, the present application proposes a display method, including: randomly acquiring a first gray-scale value and a second gray-scale value of two sub-pixels in a pixel unit 11; acquiring a first average value of the first gray scale value and the second gray scale value; when the first average value is smaller or larger than 128, the gray-scale values of the two sub-pixels in the pixel unit 11 are adjusted to be equal to 128. According to the method and the device, on the basis of not changing original brightness, the thin film transistor driving framework is compatible with the existing large visual angle algorithm, and the technical problem that the chromaticity visual angle of the existing display panel is narrow is solved.
The present application also proposes a display device 300.
Referring to fig. 4, the display device 300 mainly includes a timing controller 301, a source driver 302, a gate driver 303, the display panel 100, and a common voltage output terminal 305.
In the present embodiment, the timing controller 301 transmits a luminance signal and a polarity control signal to the source driver 302, and transmits a scan signal to the gate driver 303. The source driver 302 outputs a data voltage, the common voltage output terminal 305 outputs a common voltage, and a voltage difference between the data voltage and the common voltage (i.e., a driving voltage) drives the liquid crystal molecules to rotate to complete the display, so that the display panel 304 displays an image, and when the data voltage is higher than the common voltage, the polarity of the driving voltage is positive; on the contrary, the polarity of the driving voltage is negative, thereby realizing the inversion of the liquid crystal molecules.
