Problems solved by technology

However, after continuous application and research in the later stage, it was found that the use of the above-mentioned gamma adjustment test fixture has the following defects: 1. The angle of the working platform of the test fixture is not fixed, and the compatibility of the platform test fixture is poor; 2. The test fixture The operation is mainly completed by manual operation, the operation efficiency is low, and there are certain operation errors, which is not conducive to industrial automation operations
The above defects limit the test efficiency of gamma adjustment to a certain extent, and increase the test cycle and test cost

Abstract

The invention discloses a gamma adjusting method used for a liquid crystal screen. Single station Gamma equipment is used to realize. The single station Gamma equipment uses mutual matching of a detection apparatus, an automatic conduction apparatus and a liquid crystal screen test carry tool, and uses a vacuum apparatus to adsorb and fix a liquid crystal screen to be tested so as to realize a liquid crystal screen gamma adjusting process. In the disclosed gamma adjusting method of the liquid crystal screen, through fixing a work platform angle, compatibility of a test platform is increased; a structure component of a test carry tool unit is preferentially selected to position the liquid crystal screen with different sizes so as to realize detection of the liquid crystal screen with the different sizes; and a corresponding man-machine interaction device is arranged so that a detection rate of gamma adjusting is increased, detection cost is reduced and detection precision is increased.

Description

technical field [0001] The invention belongs to the field of liquid crystal screen detection, and in particular relates to a gamma adjustment method of a liquid crystal screen. Background technique [0002] With the rapid development of flat panel displays and the improvement of people's living standards, liquid crystal display screens have been widely used in daily life and industrial production, and their application fields and application forms are becoming more and more diverse. [0003] With the continuous expansion of the application field of LCD screens and the continuous improvement of people's requirements for the quality of LCD screens, it is necessary to perform gamma tuning on the LCD screen after the production of the LCD screen to find the best "gray-brightness" The curve can achieve the effect that the color change of the LCD screen displayed by the human eye is linear without distortion. However, since traditional gamma adjustment equipment can only perform ...
