Embodiment Construction

[0039] see figure 1 , which is a flow chart of the compression method of the gray scale compensation table of the OLED display panel of the present invention, the present invention mainly includes:

[0040]Step 10. When transmitting a set of gray-scale compensation tables of the OLED panel to the encoder for encoding, first perform a difference between multiple gray-scale compensation tables with the same color channel and different gray scales in the set of gray-scale compensation tables Operation to obtain the corresponding reference image and difference image as a substitute for the plurality of gray scale compensation tables;

[0041] Step 20, transmit the corresponding reference image and differential image to the encoder as a substitute for the plurality of gray scale compensation tables;

[0042] Step 30, the encoder encodes and compresses the received gray scale compensation table.

[0043] see figure 2 , which is an overall algorithm flow chart of a preferred embo...

Abstract

The invention relates to a method for compressing a gray scale compensation table of an OLED display panel. The method for compressing the gray-scale compensation table of the OLED display panel includes: step 10, when transmitting a group of gray-scale compensation tables of the OLED panel to the encoder for encoding, firstly have the same color in the group of gray-scale compensation tables channel, and multiple gray-scale compensation tables of different gray scales to perform differential operations to obtain the corresponding reference image and differential image as a substitute for the multiple gray-scale compensation tables; step 20, using the corresponding reference image and differential image as the The replacements of the multiple gray scale compensation tables are transmitted to the encoder; step 30, the encoder encodes and compresses the received gray scale compensation table. The method for compressing the gray-scale compensation table of the OLED display panel of the present invention performs frame-level difference between the same color component and different gray-scale compensation tables in the same group of OLED compensation tables, thereby improving the efficiency and performance of the compressed compensation table.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for compressing a gray scale compensation table of an OLED display panel. Background technique [0002] Organic light-emitting diode (OLED) display devices have self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, and wide operating temperature range, which can realize flexible display and large-area full-color display And many other advantages, it is recognized by the industry as the display device with the most development potential. According to the driving method, OLED display devices can be classified into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED). Among them, AMOLED has pixels arranged in an array, belongs to the active display type, has high luminous efficiency, and is usually used as a high-defini...
