Optimizing method and equipment for brightness compensation data volume

Abstract

Provided are a method and device for optimizing a brightness compensation data (D) volume. The method comprises: providing a panel (1) to undergo compensation, the panel (1) having a brightness compensation data storage device (11) storing multiple brightness compensation data items (D) of the panel (1); connecting to an external data processor (12) having an external storage device (121), the external storage device (121) storing determination information determining whether the brightness compensation data items (D) require compensation; the data processor (12) reading the brightness compensation data items (D), classifying, according to the determination information, the brightness compensation data items (D) into multiple data items to undergo compensation (CD) and multiple data items not requiring compensation (ND), and storing the determined multiple data items to undergo compensation (CD) and the multiple data items not requiring compensation (ND) in the external storage device (121); and reading and storing, by means of the brightness compensation data storage device (11), the data items to undergo compensation (CD) in the external storage device (121).

Description

technical field [0001] The invention relates to a method and equipment for optimizing the amount of brightness compensation data, in particular to a method and equipment for optimizing the amount of brightness compensation data through information stored in an external memory. Background technique [0002] Flat-panel display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. Existing flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic light emitting diode display devices (Organic Light Emitting Display, OLED). Organic light-emitting diode display devices have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, and relatively simple structure and manufacturing process. It is considered as an emergi...

Problems solved by technology

[0007] At present, this method is relatively simple and easy, but the premise of calculating the brightness compensation data is to assume that the panel to be compensated is already a standard Gamma2. To be accurately controlled, and the center point to be compensated (mura) generally cannot be eliminated, so it will be easier to affect the final effect of Demura

[0008] At the same time, by default, the calculation will be performed for each area, and in order to ensure the Demura effect, the minimum unit of the area to be compensated should not be too large (generally 8*8 pixel units), so the final brightness compensation data of the entire panel to be compensated The amount will be larger, so the capacity of the external memory (Demura flash) will be larger, and the internal RAM of the processing IC on the driver board will also be larger, which will also bring limitations on data transmission time and rate.
