A multi-channel gamma adjustment method and device

Abstract

The invention relates to a multichannel gamma adjustment method and device. In particular, as for each to-be-adjusted OLED module, a corresponding image printing instruction is independently outputted, the module thus presents a W0-255 image corresponding to a gamma binding point; each to-be-adjusted OLED module shares gamma adjustment parameters configured by an upper software interface, the gamma adjustment parameters comprises brightness and color coordinate adjustment of each binding point and an check error ranges, the parameter information of the to-be-adjusted OLED module is acquired independently, a corresponding gamma register value is obtained, an instruction is outputted through script compilation to the corresponding to-be-adjusted OLED module to enable an image after the gammaregister value is written to be presented. The gamma adjustment system efficiency can be enhanced, the operation is more flexible, production line operation is more facilitated, realization of true multichannel system adjustment is not influenced between mutual channels, and the production line operation capacity is further improved.

Description

technical field [0001] The invention relates to a gamma adjustment method and device, in particular to a multi-channel gamma adjustment method and device. Background technique [0002] OLED (Organic Light-Emitting Diode, OLED) is also known as organic electro-laser display and organic light-emitting semiconductor. It was discovered in the laboratory by Chinese-American professor Ching W.Tang in 1979. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast, low power consumption, and extremely high response speed. However, as a high-end display, the price will be more expensive than LCD TVs. [0003] At present, OLED manufacturing technology is still in the stage of continuous development, and major panel manufacturers are conducting experimental verification and trial production. Due to the immaturity of the manufacturing process technology, there must be differences in the modules produced. This difference will...

Problems solved by technology

Due to the immaturity of the manufacturing process technology, there must be differences in the modules produced. This difference will directly lead to differences in the initial gamma of some modules in a batch of modules, which will affect the efficiency and effect of gamma debugging.

[0004] At present, the multi-channel OLED gamma adjustment system adopts a single-threaded multi-channel simultaneous adjustment method. This test method encounters some modules with inconsistent manufacturability, which will lead to low adjustment efficiency and inflexible operation, because they can only be uploaded at the same time. For multi-block modules, when some modules are produced, the gamma adjustment takes a long time, while other modules take a long time to adjust, and need to wait for the next film, resulting in a waste of time

The operation is not flexible enough. In an emergency, the adjustment of the single-chip module cannot be terminated, and another module cannot be reconnected to start the adjustment of the single-chip module.
