And acquiring the light and dark stripe positions of the whole screen, performing gray scale adjustment on the whole screen according to the light and dark stripe positions, judging whether the picture after the gray scale adjustment meets the preset condition, if so, finishing the gray scale adjustment, and if not, continuing to perform the gray scale adjustment until the preset condition is met. By adjusting the gray scale of the whole screen, the picture can become high frequency, so that people can not visually see the horizontal stripes, and the problem that the horizontal stripes appear on the picture observed at different azimuth angles in a double-domain mode is solved.
The above steps are explained as follows:
step S301 may specifically adopt the following manner: the position of the dark stripe and the position of the bright stripe are obtained by lighting the panel to display 64 gray-scale pictures, and two situations generally exist, namely, the situation 1: the odd lines are darker and the even lines are brighter; case 2: the odd rows appear brighter and the even rows appear darker.
After the light and dark stripe position of the whole screen is acquired, step S302 is executed, wherein step S302 further includes the steps of:
increasing preset gray scale values to the dark stripes every other preset pixels; and reducing the preset gray level value of the bright stripes every other preset pixels. The following method can be specifically adopted:
in this embodiment, it is preferable that 2 × 2 pixels are one period in units of pixels, that is, every other pixel of the dark stripes is increased by a predetermined gray scale value, and every other pixel of the bright stripes is decreased by the predetermined gray scale value, and the entire screen is processed, as shown in fig. 4 (in fig. 4, it is to be noted that the odd rows are displayed darker, and the even rows are displayed brighter).
In other embodiments, the preset gray-scale value may be increased or decreased by selecting every other pixel according to actual conditions, which is not limited herein.
The following description is provided for the two cases of dark odd-numbered lines, bright even-numbered lines, bright odd-numbered lines and dark even-numbered lines, respectively:
