Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Implementations of various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself.

[0041] Such as figure 1 As shown, a gamma correction method for a display module proposed in the first embodiment of the present invention includes:

[0042] 101. Acquire a time parameter value stored in a time register.

[0043] In this embodiment, the time parameter value stored in the time register and the compensation times parameter value stored in the compensation times register can be set according to the relationship between brightness and time of the display module.

Abstract

The invention discloses a gamma correction method and apparatus for a display module group. The method comprises: a time parameter value registered by a time register is obtained; the obtained time parameter value is assigned to a counter and the counter is started to start counting; if the counter completes timing, a compensation frequency parameter value registered by a compensation frequency register is corrected; gamma register value adjustment is carried out on one group of pre-stored compensation values corresponding to all gray scales and gamma correction is carried out on a display module group. According to the gamma correction method and apparatus disclosed by the invention, gamma register value adjustment can be carried out on one group of pre-stored compensation values corresponding to all gray scales and thus gamma correction is carried out on the display module group. Therefore, the device luminance can be compensated automatically; the color cast can be eliminated; and the influence on the display effect by device aging can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gamma correction method and device for a display module. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) display device is an emerging flat panel display device, compared with liquid crystal display (Liquid Crystal Display, LCD), OLED can self-illuminate without backlight unit, therefore, in general sense OLED display devices are considered to consume less power than LCDs. [0003] A pixel unit in an OLED display device includes a plurality of pixel units arranged in a matrix. According to the driving mode, the pixel unit is divided into two types: a passive matrix (Passive Matrix, PM) driving mode and an active matrix (Active Matrix, AM) driving mode. Because AMOLED has obvious advantages in viewing angle, color reproduction, power consumption, and response time, it has been widely used. [0004] In the process of pra...
