Problems solved by technology

In addition, with the continuous popularization of display devices, the existing TFT-LCD has many advantages in terms of color quality, contrast, viewing angle, response speed, etc., but there are still some aspects that need further improvement, such as the picture quality of TFT-LCD. Flicker phenomenon (TFT-LCD Flicker), this is because the gray scale of the displayed screen will change slightly every time the screen is updated, making the human eye feel that the screen is flickering
[0003] Existing TFT-LCD flickers generally adjust the input voltage manually to achieve the best panel flicker. However, when the panel is used for a long time and ages, the panel flicker will become worse, so it is necessary to adjust the input voltage twice or multiple times. And after the whole machine is formed, it cannot be adjusted, so it is time-consuming and laborious, and the operation has certain limitations

Embodiment 1

[0042] Embodiments of the present invention provide a method for self-adjusting panel flicker, such as figure 1 shown, including:

[0043] S101. The device for self-adjusting panel flicker obtains a relationship curve between the public voltage value and the panel usage time when the panel screen flicker value is the smallest.

[0044] Before obtaining the relationship curve between the public voltage value and the panel use time when the flicker value of the panel screen is the smallest, it is necessary to first obtain the relationship curve between the panel use time and the flicker value of the panel screen, and obtain the The public voltage value corresponding to the minimum flicker value of the panel screen, and the relationship curve between the panel use time and the flicker value of the panel screen and the relationship curve between the public voltage value and the flicker value of the panel screen are obtained. A relationship curve between the public voltage value a...

Embodiment 2

[0049] Embodiments of the present invention provide a method for self-adjusting panel flicker, such as figure 2 shown, including:

[0050] S201. The device for self-adjusting panel flicker obtains the flicker value of the panel screen every preset time, obtains the time point corresponding to the flicker value of the panel screen every preset time, and obtains every preset time according to the acquisition The flickering value of the panel screen and the time point corresponding to the acquisition of the flickering value of the panel screen every preset time are used to obtain a relationship curve between the panel usage time and the flickering value of the panel screen.

[0051] First set a time, which can be 1 hour, 2 hours or other time, and then every set time, through the optical equipment to test the flicker value of the screen at different times when the panel is turned on, and record it, and then you can pass the test The screen flicker value of the panel at differen...

Embodiment 3

[0064] An embodiment of the present invention provides a device 1 for self-adjusting panel flicker, such as Figure 6 shown, including:

Abstract

The embodiment of the invention discloses a panel flicker self-regulation method and device and relates to the technical field of display. The panel flicker self-regulation method and device solve the problems that in the displayer panel flicker regulating process, manual regulation of input voltage consumes time and labor and operations are limited. According to the specific scheme, the relation curve between common voltage values generated when a panel flicker value is the minimum and the service life of a panel is acquired, and when the panel is used, the common voltage value corresponding to the current moment is periodically or non-periodically regulated according to the relation curve between the common voltage values and the service life of the panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and device for self-adjusting flicker of a panel. Background technique [0002] With the continuous advancement of display technology, users' demand for display devices continues to increase. TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor Liquid Crystal Display) has been widely used in mobile phones, liquid crystal displays, tablet computers and other products. Applications. In addition, with the continuous popularization of display devices, the existing TFT-LCD has many advantages in terms of color quality, contrast, viewing angle, response speed, etc., but there are still some aspects that need further improvement, such as the picture quality of TFT-LCD. Flicker phenomenon (TFT-LCD Flicker), this is because the gray scale of the displayed screen will change slightly every time the screen is updated, which makes the human eye f...
