Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. "upper", "lower", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
The display panel of the embodiment includes: a plurality of gate lines and a plurality of data lines; the grid line and the data line are arranged in a crossed manner to define a pixel area; at least one sub-pixel is arranged in each pixel area; the sub-pixels in each pixel area are connected with a data line; sub-pixels in adjacent pixel areas positioned in the same column are connected with different data lines; the sub-pixels in the pixel regions of two adjacent rows in two adjacent columns are connected with the same data line, and the sub-pixels in the two pixel regions are connected with different grid lines.
Specifically, as shown in fig. 1, the present embodiment is described by taking an example in which one sub-pixel is disposed in each pixel region, wherein the sub-pixel may be one of a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Of course, two sub-pixels and the like may be disposed in each pixel region, which is not limited herein.
In addition, it should be noted that if all the pixel regions in the display panel are considered as a whole, the whole is the entire pixel region of the display panel of this embodiment, at this time, the data input end of the entire pixel region is provided with a source driving circuit (not shown in fig. 1), and the source driving circuit is respectively electrically connected to the plurality of data lines and is used for transmitting data voltages to the data lines.
Example 1:
as shown in fig. 2, the present embodiment provides a display method of a display panel, including the following steps:
s1, obtain a sub-pixel at the center of the display panel, which is referred to as a first sub-pixel, and a sub-pixel located in an adjacent row to the first sub-pixel and connected to the same data line, which is referred to as a second sub-pixel.
It can be seen that the first sub-pixel and the second sub-pixel of the present embodiment are two sub-pixels connected to the same data line in two adjacent rows, respectively. Specifically, as shown in fig. 1, in the present embodiment, along the top-to-bottom direction, the red sub-pixels R located in the third row and the fourth column (i.e., the red sub-pixels R in the dashed line area in fig. 1) are taken as the first sub-pixels, and the blue sub-pixels B located in the fourth row and the third column (i.e., the blue sub-pixels B in the dashed line area in fig. 1) are taken as the second sub-pixels for explanation.
And S2, acquiring data voltages of the first sub-pixel and the second sub-pixel when the display panel displays the picture, and respectively recording the data voltages as an initial data voltage and a termination data voltage.
Wherein, the step S2 specifically includes: firstly, when the display panel displays a picture, the gray-scale values of the red sub-pixel R and the blue sub-pixel B obtained in step S1 are respectively obtained and recorded as a first gray-scale value and a second gray-scale value; then, according to the gamma voltage division, a start data voltage corresponding to the first gray scale value and an end data voltage corresponding to the second gray scale value are obtained.
It should be noted that the Gamma voltage division (Gamma voltage division) includes a corresponding relationship between different data voltages and different gray scale values, or a corresponding relationship between different gray scale values and different data voltages. That is, when the data voltage is known, the gray value corresponding to the known data voltage can be obtained according to the gamma voltage division; similarly, when the gray scale value is known, the data voltage corresponding to the known gray scale value can be obtained according to the gamma voltage division.
S3, adjusting the image displayed on the display panel to make the display image reach a preset display mode, obtaining the data voltage of the second sub-pixel, and recording the data voltage as the actual data voltage.
It should be noted that, the reason why the picture displayed on the display panel needs to be adjusted is that when the display panel performs normal display, the electric quantity charged in the pixels of two adjacent rows has a certain difference, so that a visible fine line appears on the display picture displayed on the display panel, and the fine line is very likely to affect the viewing effect of the user using the display panel. It is obvious that, as can be seen, the aforementioned preset display mode means that the display panel is no longer provided with fine lines.
Wherein, the step S3 specifically includes: firstly, adjusting the picture displayed on the display panel to make the picture displayed on the display panel no longer have fine lines, and at this time, acquiring the gray-scale values of the blue sub-pixels B located in the fourth row and the third column, acquired in step S1; then, the actual data voltage corresponding to the gray-scale value of the blue subpixel B is acquired again according to the gamma voltage division. It is understood that, at this time, the actual data voltage of the blue sub-pixel B should be greater than the termination data voltage thereof acquired in step S2.
And S4, acquiring the reference voltage change rate according to the initial data voltage, the termination data voltage and the actual data voltage and a preset algorithm.
Specifically, in this step, the reference voltage change rate is obtained according to the initial data voltage value and the end data voltage obtained in step S2 and the actual data voltage obtained in step S3, and according to a preset algorithm. Wherein, hereinThe preset algorithm may be c ═ V (V)B-VA)/(VC-VA) (ii) a Wherein c is a reference voltage change rate, VAIs an initial data voltage, VBTo terminate the data voltage, VCIs the actual data voltage.
And S5, acquiring an actual gray scale value according to the initial gray scale value, the termination gray scale value and the reference voltage change rate, and generating a first mapping table.
It should be noted that the initial gray scale value and the termination gray scale value are both known gray scale values, that is, as shown in fig. 3, the values of 0, 32, 64, 96, etc. in the first row are the initial gray scale values of this embodiment, and the values of 0, 32, 64, 96, etc. in the first column are the termination gray scale values of this embodiment.
That is, in this step, first, known initial gray scale values and known end gray scale values are obtained; then, according to the gamma voltage division, the initial data voltage V corresponding to the initial gray-scale value and the ending gray-scale value is respectively obtainedAEnd data voltage VBAnd according to the reference voltage change rate c obtained in step S4, and the preset algorithm c ═ VB-VA)/(VC-VA) That is, the actual data voltage V can be obtainedC(ii) a Finally, the voltage V is obtained and actually compared according to the gamma voltage divisionCThe corresponding actual gray scale values, for example: when the initial gray scale value is 32 and the final gray scale value is 64, the actual gray scale value 65 corresponding to the initial gray scale value and the final gray scale value can be obtained according to a preset algorithm. Thus, the step S5 is repeated several times, so that the first mapping table shown in fig. 3, i.e. the corresponding relationship table of different initial gray-scale values, different ending gray-scale values and different actual gray-scale values, can be generated.
And S6, adjusting the data voltage on the data line when the display panel displays according to the first mapping table generated in the step S5.
Specifically, when a certain row of gate lines is scanned, all the pixels in the row are turned on, and at this time, according to the first mapping table generated in step S5, the data voltages on the data lines connected to each sub-pixel in the row are respectively adjusted, so that each sub-pixel in the row can normally display.
S7, acquiring the display mode of each sub-region when the display panel displays according to the first mapping table, adjusting the numerical value which is stored in the second mapping table and corresponds to the sub-region according to the display mode, and adjusting the data voltage on the data line again according to the adjustment result; the second mapping table is a corresponding relation table of different sub-areas and different values.
Note that, the display mode of each sub-region described above means: and when the display panel displays according to the first mapping table, whether each sub-area has fine lines or not is judged. In addition, the size range of different values stored in the second mapping table is 0-255; when the value 128 is a reference value, that is, when the display panel displays according to the first mapping table generated in step S5, if the value corresponding to a sub-region is 128, it indicates that the data voltage of the sub-region is the data voltage corresponding to the actual gray scale value in the first mapping table, and the display image displayed by the sub-region does not have fine lines. Correspondingly, when the value corresponding to a sub-region is greater than or less than 128, it indicates that there is a fine-line in the display screen displayed by the sub-region.
Specifically, the display panel of the present embodiment includes a plurality of sub-regions arranged in an array, wherein as shown in fig. 4, the present embodiment is described by taking an example in which the display region of the display panel is divided into 28 sub-regions (i.e., the X1Y1 sub-region, the X1Y2 sub-region, the X1Y3 sub-region, the X1Y4 sub-region, the X2Y1 sub-region, etc. shown in fig. 4).
The step S7 includes: when the display panel displays according to the first mapping table generated in step S5, acquiring the display mode of each sub-region, in this case, if taking the sub-region X1Y1 as an example, acquiring the display mode of the sub-region X1Y1, when the sub-region X1Y1 does not have fine lines, the value corresponding to the sub-region X1Y1 in the second mapping table should be 128, and at this time, there is no need to adjust the data voltage on the data lines; when the sub-area X1Y1 has a fine line, adjusting the value corresponding to the sub-area X1Y1 stored in the second mapping table until the sub-area X1Y1 does not have a fine line; when the adjusted value is greater than 128, it indicates that the data voltage required by the sub-area X1Y1 should be greater than the data voltage corresponding to the actual gray level value in the first mapping table, and at this time, to solve the problem of the fine texture, the data voltage on the data line should be increased; when the adjusted value is smaller than 128, it indicates that the data voltage required by the sub-area X1Y1 should be smaller than the data voltage corresponding to the actual gray level in the first mapping table, and at this time, to solve the problem of the fine texture, the data voltage on the data line should be reduced.
And displaying the display panel after the operation is finished.
In summary, the display method of the display panel provided in this embodiment mainly obtains the first mapping table including the corresponding relationships between different initial gray-scale values, different ending gray-scale values and different actual gray-scale values according to the calculated reference voltage change rate, so that when the display panel performs display according to the first mapping table, the data voltages on the data lines are uniformly adjusted. Meanwhile, when the display panel displays by using the display method provided by the embodiment, the data voltage on the data line is adjusted for the second time by using the second mapping table, so that the defect that the data line and the gate line have certain resistance is further overcome, fine lines do not appear on the display picture, and the experience of a user using the display panel of the embodiment is improved.
