Abstract

The invention provides an image data storage method and device, and belongs to the technical field of image display. The image data storage method comprises the steps: obtaining an image display requirement, including image quality or response speed required by an image; determining a data compression ratio corresponding to the display requirement; compressing the image data of the image according to the data compression ratio and storing the compressed image data in an RAM of a driving chip. The invention solves a problem of great limitation because of the fact that compression and storage can be performed only according to a constant compression ratio in correlation technology; an effect that the data compression ratio can be flexibly adjusted according to the display request of the image to adapt to various scenarios is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of image display, and in particular to an image data storage method and device. Background technique [0002] In order to buffer the image data of the image to be displayed, the driver IC (Integrated Circuit integrated circuit) of the display screen is usually provided with a RAM (Random Access Memory, random access memory) for buffering the image data. [0003] In the related art, the RAM of the driving IC generally has two specifications, one is 1 / 2 RAM corresponding to a data compression ratio of 1 / 2, and the other is 1 / 4 RAM corresponding to a data compression ratio of 1 / 4. Taking RAM as an example of 1 / 2RAM corresponding to 1 / 2 data compression ratio, the terminal compresses the image data of the image to be displayed with a 1 / 2 compression ratio, and stores the compressed image data in the RAM of the driver IC . [0004] However, in the technical solution provided above, the display data can...
