Problems solved by technology

[0003] However, the inventor found in the process of implementing the present invention that if the sampling point is inappropriate when using fixed point calibration, the calibration error will be large, and when the method of point-by-point calibration is used to correct each sampling point individually, the calculation of the current point cannot be applied in time The calculation to the next point is inefficient and prone to errors

Abstract

The invention discloses a display device display parameter correction method comprising the following steps: obtaining the maximum debug point and the minimum debug point of a to-be-corrected displaydevice, and obtaining the maximum brightness according to the maximum debug point; calculating to form a first Gamma check table according to the maximum brightness and the minimum brightness of the display device; forming debug points of a preset number according to the maximum debug point and the minimum debug point; forming a debug point set according to each debug point and correction data obtained by correcting each debug point; arranging the debug point set according to the correction data and the first Gamma check table, thus obtaining a second Gamma check table; fitting according to the second Gamma check table so as to form a Gamma correction curve and a third Gamma check table. The invention also discloses a display device display parameter correction device, terminal equipment and a storage medium, thus improving the correction point selection accuracy and validity, providing more accurate correction data, and improving the user experiences.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display parameter correction method, device, terminal equipment and storage medium of a display. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of technology, display devices such as LCD TVs and electronic whiteboards have become more and more popular. In order to obtain visual comfort, the user's requirements for the display quality of the display device are getting higher and higher, and adjusting the gamma curve is a very important factor to improve the display quality (such as brightness and color temperature). measure. At present, the method of fixed-point calibration or point-by-point calibration is generally used to correct the gamma curve, so that the picture of the display screen is pure and delicate, and the color is truly restored. [0003] However, the inventor found in the process...
