CHROMINANCE VISUAL ANGLE CORRECTION METHOD FOR DISPLAY, AND INTELLIGENT TERMINAL AND STORAGE MEDIUM
A chrominance visual angle correction method for a display (30), and an intelligent terminal and a storage medium. The method comprises: acquiring data of the brightness of different primary colors varying with the gray scale at a vertical visual angle and a squint visual angle, and generating a search database (S10); splitting, according to the search database and a present rule, the pixel gray scale of the display (30) into a plurality of high and low gray scale combinations composed of high gray scales and low gray scales (S20); and calculating the scale of brightness of the plurality of high and low gray scale combinations, and acquiring a high and low gray scale combination the scale of brightness of which is closest to the scale of vertical vision brightness as a primary color pixel gray scale (S30). By means of making primary colors have the same scale of brightness at the vertical visual angle and the squint visual angle, the chrominance visual angle of the display (30) is improved, such that the squint visual angle can be improved without changing the performance at the vertical visual angle, thereby greatly improving a viewing effect of the display (30) at the squint visual angle, and facilitating a large-visual-angle application scenario of the display (30).

The system may adjust an image to be displayed on the display using the custom correction map. The custom correction map may correct non-uniformity of the display as viewed from the eye of the user. The system may display the image adjusted using the custom correction map on the display.
