Description

Double-gate panel display method
Technical Field
The invention relates to the technical field of panel display, in particular to a double-gate panel display method.
Background
Cell phone manufacturers have successively released full-screen cell phones, which require the lower bezel of the cell phone panel to be narrowed. Compared with a single-gate panel, the number of data wires of the double-gate panel is reduced to half of the original number, so that the area of a data line wiring area (fan-out area) of the panel is smaller; the effect that the lower frame of the panel becomes narrow is achieved, and finally the full-face screen is achieved.
However, the dual-gate panel still has the problem of poor display, the dual-gate panel displays double row inversion, i.e. the liquid crystal polarity is two rows positive and two rows negative, compared with the single-gate panel which displays single row inversion, the dual-gate panel displays each frame with lower spatial frequency, and human eyes are more sensitive to low frequency, and the liquid crystal polarity has brightness difference between positive and negative. The human eyes watch the picture in integral mode, generally, the time of two frames is integrated (default 60Hz display), and when the human eyes watch the pure-color picture of the double-gate panel in a shaking mode, only one frame of picture is watched, so that the straight-line phenomenon can be seen; when the panel is watched without shaking the head, the positive and negative polarities of the liquid crystal are continuously reversed, and the straight stripe phenomenon disappears when the integral of two or more frames with the positive liquid crystal polarity and the negative liquid crystal polarity is observed.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: a display method capable of improving the straight-line phenomenon of a dual-gate panel is provided.
In order to solve the technical problems, the invention adopts the technical scheme that:
a double-gate panel display method comprises the following steps:
s1, adjusting the gray-scale values of all the pixel points in the double-gate panel to obtain the adjusted gray-scale value corresponding to each pixel point;
s2, comparing the adjusted gray scale value corresponding to each pixel point obtained in the step S1 with a preset gray scale reference value respectively to obtain a difference value corresponding to each pixel point;
s3, judging whether the difference value corresponding to each pixel point obtained in the step S2 is within a preset gray scale change threshold value;
s4, if yes, controlling the double-gate panel to input high level and collecting the brightness values of all pixel points in the double-gate panel;
s5, judging whether the brightness values of all the adjacent pixel points with the same polarity acquired in the step S4 are equal or not;
s6, if yes, repeating the steps S1-S5, and executing a step S7 when the brightness values of all the adjacent pixels with the same polarity, which are acquired in the step S4, are not equal;
and S7, controlling the double-grid panel to input low level.
The invention has the beneficial effects that:
the gray-scale values of all pixels in the double-gate panel are adjusted, so that when the double-gate panel is in a lighting state (namely, a high level is input), the brightness values of adjacent pixel points with the same polarity are unequal, and at the moment, when the double-gate panel displays a pure-color picture or a gray-scale picture, the panel is not a low-frequency picture in space any more but a high-frequency picture, so that the straight-line phenomenon of the double-gate panel disappears. The display method designed by the scheme can solve the straight grain phenomenon of the double-gate panel without changing the panel design, reduces the manufacturing process difficulty and improves the quality of the panel.

Detailed Description
In order to explain the technical contents, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1, the technical solution provided by the present invention is:
a double-gate panel display method comprises the following steps:
s1, adjusting the gray-scale values of all the pixel points in the double-gate panel to obtain the adjusted gray-scale value corresponding to each pixel point;
s2, comparing the adjusted gray scale value corresponding to each pixel point obtained in the step S1 with a preset gray scale reference value respectively to obtain a difference value corresponding to each pixel point;
s3, judging whether the difference value corresponding to each pixel point obtained in the step S2 is within a preset gray scale change threshold value;
s4, if yes, controlling the double-gate panel to input high level and collecting the brightness values of all pixel points in the double-gate panel;
s5, judging whether the brightness values of all the adjacent pixel points with the same polarity acquired in the step S4 are equal or not;
s6, if yes, repeating the steps S1-S5, and executing a step S7 when the brightness values of all the adjacent pixels with the same polarity, which are acquired in the step S4, are not equal;
and S7, controlling the double-grid panel to input low level.
From the above description, the beneficial effects of the present invention are:
the gray-scale values of all pixels in the double-gate panel are adjusted, so that when the double-gate panel is in a lighting state (namely, a high level is input), the brightness values of adjacent pixel points with the same polarity are unequal, and at the moment, when the double-gate panel displays a pure-color picture or a gray-scale picture, the panel is not a low-frequency picture in space any more but a high-frequency picture, so that the straight-line phenomenon of the double-gate panel disappears. The display method designed by the scheme can solve the straight grain phenomenon of the double-gate panel without changing the panel design, reduces the manufacturing process difficulty and improves the quality of the panel.
Further, step S1 is specifically:
increasing the gray-scale values of the pixel points of the pixel units positioned in odd-numbered rows and odd-numbered columns in more than two pixel unit groups in the double-gate panel and the gray-scale values of the pixel points of the pixel units positioned in even-numbered rows and even-numbered columns to obtain the adjusted gray-scale value corresponding to each pixel point;
the gray-scale values of the pixel points positioned in the odd-numbered rows and the even-numbered columns in the pixel unit groups of more than two pixel units in the double-gate panel are kept unchanged.

the gray-scale values of the pixel points positioned in the odd-numbered rows and the even-numbered columns in the pixel unit groups of more than two pixel units in the double-gate panel are kept unchanged.
Furthermore, the gray scale value of the pixel point of each pixel unit group has the same change, and more than two pixel unit groups are distributed in an array;
one pixel unit group includes four pixel units and constitutes an arrangement structure with a column number of 2 and a row number of 2.

the gray-scale values of the pixel points of the pixel units positioned in other rows and columns in more than two pixel unit groups in the double-gate panel are kept unchanged.

In summary, according to the dual-gate panel display method provided by the present invention, the gray-scale values of all pixels in the dual-gate panel are adjusted, so that when the dual-gate panel is in a lighting state (i.e. a high level is input), the brightness values of the adjacent pixels with the same polarity are not equal, and at this time, when the dual-gate panel displays a pure color picture or a gray-scale picture, the panel is not a low-frequency picture but a high-frequency picture, so that the straight-line phenomenon of the dual-gate panel disappears. The display method designed by the scheme can solve the straight grain phenomenon of the double-gate panel without changing the panel design, reduces the manufacturing process difficulty and improves the quality of the panel.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
