Embodiment Construction

[0036] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0037] see figure 1 , the present invention provides a method for compressing a compensation table of an OLED display device, comprising the following steps:

[0038] Step S1, obtaining a compensation table to be compressed, which includes a plurality of sequentially arranged data to be compressed;

[0039] Step S2, sequentially read the data to be compressed in the compensation table to be compressed, and when the number of consecutively read data to be compressed with the same value exceeds or equals the preset number threshold, then for those data to be compressed Run-length encoding is performed on the compressed data to generate corresponding compressed data, and the compressed data is written into the compressed file, otherwise the read...

Abstract

The invention provides a compensation table compression method and a decompression method for an OLED display device. The compensation table compression method for an OLED display device compresses data size of compensation tables through run-length coding of data which is arranged continuously and equal in values in the compensation tables, and through adjusting the size of a preset number threshold value, condition of the run-length coding to start is controlled, to prevent to increase redundancy and expand data size caused by coding. The method can compress size of the compensation tables, reduce system storage space occupied by the compensation tables, and shorten time for transmitting and burning data on a production line.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation table compression method and decompression method of an OLED display device. Background technique [0002] Organic Light Emitting Display (OLED) has self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response, can be used for flexible panels, wide operating temperature range, structure It is considered to be an emerging application technology for the next generation of flat panel displays due to its excellent characteristics such as simple manufacturing process. [0003] OLED display devices generally include: a substrate, an anode disposed on the substrate, an organic light-emitting layer disposed on the anode, an electron transport layer disposed on the organic light-emitting layer, and a cathode disposed on the electron transport layer. When working, emit holes from the anode and electrons from the cathode to the organic l...
