Abstract

The invention provides a display compensation method for a display panel. The display compensation method comprises the following steps: setting a first random access memory and a second random accessmemory; executing a first display compensation mode in a first time period; executing a second display compensation mode in a second time period, wherein the first time period and the second time period are independent of each other; the step of executing the first display compensation mode includes reading first compensation data and storing the compensation data in the second random access memory; and the step of executing the second display compensation mode includes reading second compensation data and storing the second compensation data in the first random access memory and the second random access memory. According to the display compensation method for the display panel provided by the invention, the first random access memory and the second random access memory jointly store thesecond compensation data, and the information amount of the second compensation data is larger than the capacity of the second random access memory, so as to compensate for uneven display and optimizea display effect, avoid the problem that the display effect is poor due to the fact that the first compensation data are used for compensation, and the information amount of the first compensation data is less than or equal to the capacity of the second random access memory.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display compensation method for a display panel. 【Background technique】 [0002] In the prior art, the display panel tends to be thinner and lighter, and the random access memory therein is set to a small size / small capacity; the display panel uses a single-level gray scale to display images in the gray scale of 0 to 255, and the compensation for the single-level gray scale The data has a small amount of information, the random access memory can read and store the compensation data for the single-level gray scale, and the display panel can perform compensation for the single-level gray scale and achieve uniform display of the single-level gray scale. However, the display panel uses multi-level gray scales from 0 to 255 gray scales to display images, and the compensation data for the multi-level gray scales has a large amount of information, and the RAM cannot read and store ...
