  • Patent number: 10916175
    Abstract: A method for correcting uniformity of a panel is provided. A display panel is set with four color patterns respectively, and respective raw data of the four color patterns are respectively measured by an optical instrument. Three primary color chromaticity variations are obtained based on the raw data of each of the four color patterns. A chromaticity uniformity table is obtained based on the chromaticity variations of three primary colors and chromaticity intensity. A proportional calculation is executed for the chromaticity uniformity table to obtain a luminance comparison table. A luminance uniformity table is obtained based on the chromaticity uniformity table, the luminance comparison table, and luminance intensity. The display panel adjusts an output signal based on the chromaticity uniformity table.
