Display device, and optical compensation system and optical compensation method thereof

摘要

A display device, and an optical compensation system and an optical compensation method thereof. A display device including a display panel including pixels; and a display driving circuit for driving the display panel and including: a storage unit for storing defect pixel information indicating which of the pixels are detected as defect pixels based on a brightness trend line of the pixels, and for storing compensation parameters regarding the defect pixels; and a brightness compensation unit for converting image data corresponding to the defect pixels according to the defect pixel information and the compensation parameters.

主权项

1. A display device comprising:
a display panel comprising a plurality of pixels; and a display driving circuit for driving the display panel and comprising:
a storage unit for storing defect pixel information indicating which pixels from among the plurality of pixels are detected as defect pixels based on a brightness trend line of the plurality of pixels, and for storing compensation parameters regarding the defect pixels, wherein the brightness trend line is determined by modeling a distribution of brightness data to a form of an Nth order function (where N is an integer equal to or greater than 1) and determining an appropriateness of the form of the Nth order function based on a ratio of the defect pixels to a total number of the plurality of pixels before determining it as the brightness trend line; anda brightness compensation unit for converting image data corresponding to the defect pixels according to the defect pixel information and the compensation parameters.
