Chrominance visual angle correction method for display, and intelligent terminal and storage medium

An intelligent terminal, wherein the intelligent terminal comprises:

• a memory, a processor, and a chrominance visual angle correction program for a display that is stored in the memory and executable by the processor, to perform operations comprising:
• acquiring brightness data of primary colors Red (R), Green (G), and Blue (B) varying with gray scales at a vertical visual angle and at an oblique visual angle respectively, and generating a search database based on the brightness data;
• splitting a pixel gray scale of the display into a plurality of high and low gray scale combinations according to the search database and a preset rule, wherein each of the plurality of high and low gray scale combinations comprises a first high gray scale and a first low gray scale corresponding to R, a second high gray scale and a second low gray scale corresponding to G, and a third high gray scale and a third low gray scale corresponding to B;
• calculating a first ratio of brightness of R gray scale, brightness of G gray scale and brightness of B gray scale at the vertical visual angle before the splitting, and second ratios respectively corresponding to the plurality of high and low gray scale combinations at the oblique visual angle, wherein each of the second ratios is equal to a ratio of a sum of brightness of the first high gray scale and brightness of the first low gray scale, a sum of brightness of the second high gray scale and brightness of the second low gray scale, and a sum of brightness of the third high gray scale and brightness of the third low gray scale for one of the plurality of high and low gray scale combinations at the oblique visual angle;
• and
• determining one of the second ratios closest to the first ratio, and determining one of the plurality of high and low gray scale combinations corresponding to the one of the second ratios as a primary color pixel gray scale.

A non-transitory storage medium, wherein the storage medium stores a chrominance visual angle correction program for a display executable by a processor to perform operations comprising:

• acquiring brightness data of primary colors Red (R), Green (G), and Blue (B) varying with gray scales at a vertical visual angle and at an oblique visual angle respectively, and generating a search database based on the brightness data;
• splitting a pixel gray scale of the display into a plurality of high and low gray scale combinations according to the search database and a preset rule, wherein each of the plurality of high and low gray scale combinations comprises a first high gray scale and a first low gray scale corresponding to R, a second high gray scale and a second low gray scale corresponding to G, and a third high gray scale and a third low gray scale corresponding to B;
• calculating a first ratio of brightness of R gray scale, brightness of G gray scale and brightness of B gray scale at the vertical visual angle before the splitting, and second ratios respectively corresponding to the plurality of high and low gray scale combinations at the oblique visual angle, wherein each of the second ratios is equal to a ratio of a sum of brightness of the first high gray scale and brightness of the first low gray scale, a sum of brightness of the second high gray scale and brightness of the second low gray scale, and a sum of brightness of the third high gray scale and brightness of the third low gray scale for one of the plurality of high and low gray scale combinations at the oblique visual angle;
• and
• determining one of the second ratios closest to the first ratio, and determining one of the plurality of high and low gray scale combinations corresponding to the one of the second ratios as a primary color pixel gray scale.
