Description
Technical Field
The invention belongs to the technical field of display and test of display modules, and particularly relates to a method and a device for detecting an HDR display module and electronic equipment.
Background
High Dynamic Range (HDR) imaging is a technique used in computer graphics and cinematography to achieve a larger Dynamic Range of exposure (i.e. a larger shading difference) than Standard Dynamic Range (SDR) imaging techniques, and the purpose of HDR imaging is to accurately reflect real-world shadows.
HDR Metadata is Metadata used as a carrier of HDR content parameters, which a display module needs to use when performing HDR data analysis. The HDR Metadata at the present stage comprises HDR Static Metadata and HDR Dynamic Metadata, wherein the Static Metadata indicates that the display module maps HDR data to display pictures according to a fixed mode, and the Dynamic Metadata indicates that the display module can map the HDR data to display pictures according to different parameter modes; the current mainstream equipment mostly uses HDR Static Metadata.
Display ID is a standard established by VESA (Video Electronics Standards Association) as metadata (metadata) describing the capabilities of a Display module. It was proposed to be version 1.0 from 12 months 2007, and developed to version 2.0 by September 2017. With the development of the Display industry, the functions of modules are more and more (8K, 3D, WCG, etc.), the original description text, Extended Display Identification Data (EDID), cannot meet the requirement, so that the Extended Display Identification Data (EDID) is designed to replace the E-EDID and EDID 1.4 versions.
With the increasing living standard of people, the display performance of the household display equipment is required to be higher and higher, and the technical level of the display industry is also continuously improved. VESA has thus enacted HDR protocol standards to regulate the development of the display industry. The current VESA HDR grading standards fall into two broad categories, one is the panel (LCD) standard using backlight, HDR400, HDR 500, HDR 600, HDR 1000, and the other is the self-luminous panel (OLED) standard, HDR400 True Black and HDR 500 True Black.
Based on the above background, the popularization of HDR imaging technology can be an inevitable trend in the display industry, and has been greatly popularized at the present stage. Therefore, module manufacturers have more demands for testing equipment for detecting the HDR module, but most of the testing equipment in the market at the present stage only support the detection of the SDR module, and cannot meet the testing requirements of the HDR module.
