Embodiment 1

[0023] This embodiment provides a method for adjusting the value of the gamma register of the display, which is used for AMOLED to quickly adjust the value of the gamma register of the display, so that the value of the gamma register and its corresponding brightness value are more accurate, so as to ensure that the display displayed Images can be better restored, the method includes:

[0024] S101. Obtain a current value of a gamma register. The current value here can be an initial value preset manually or automatically. The initial value can be the value before adjustment, or the value of a gamma register obtained after trying to adjust once, which can be adjusted later by monitoring The change of the current value to judge whether the adjustment is appropriate.

[0025] S102. Monitor the current value of the gamma register corresponding to the driving current value. When the value of the register is the first gamma value, the driving current value at this time can be monit...

Embodiment 2

[0035] In this embodiment, a device for adjusting the value of the display gamma register is provided, and the structural block diagram is as follows figure 2 As shown, it includes an initial acquisition unit 001, a detection unit 002, a judgment unit 003, a loop unit 004, and a fine-tuning unit 005, wherein:

[0036]The initial acquisition unit 001 is used to acquire the current value of the gamma register, where the current value can be manually or automatically adjusted to a preset initial value.

Abstract

The invention provides a method and device for adjusting a value of a gamma register of a display. The method comprises the steps that a current value of the gamma register is obtained; a driving current value corresponding to the current value of the gamma register is monitored; whether the driving current value is a current gray scale driving current value or not is judged; if driving current is not the current gray scale driving current value, the value of the gamma register is repeatedly adjusted till the driving current value corresponding to the value is the current gray scale driving current; when the driving current value is the current gray scale driving current value, the value of the current gamma register is finely adjusted. In the scheme, the range of the value of the gamma register is rapidly locked by monitoring the driving current value, the adjusted range is rapidly and coarsely positioned, fine adjustment is performed after the coarsely positioned value of the value of the gamma register is located, accordingly the adjusting speed and precision of the value of the gamma register are effectively improved, and the problem that the value of the gamma register is low in adjusting speed, a value of a low-gray-scale gamma register is difficult to adjust and the time is consumed is solved.

Description

technical field [0001] The invention relates to the field of image display, in particular to a method and device for adjusting the value of a display gamma register. Background technique [0002] Gamma curve correction is an important technology for a display device to improve the overall display effect according to the characteristics of the main display device itself. Gamma voltage value correction refers to changing the gamma voltage value to match the middle gray scale of the monitor. Gamma voltage value correction compensates for the color display differences of different output devices, so that the image appears the same on different monitors. Effect. [0003] At present, the method to adjust the gamma voltage value of the AMOLED (Active-matrix organic light emitting diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) display screen is to use the color analyzer CA310 to monitor the brightness of the module screen And color...
