Embodiment 1

[0059] figure 1 This embodiment provides a flow chart of an HDR display module detection method, see figure 1 As shown, the method includes the following steps:

[0060] S1: Analyze the control instructions issued by the data source to obtain the interface timing and data types required by the module to be tested;

[0061] S2: Receive and analyze the HDR point screen data sent by the data source to obtain metadata corresponding to the HDR point screen data; the HDR point screen data includes image data and / or video data;

[0062] Since the display module to be tested requires different types of screen data in different application scenarios, the HDR screen data includes static picture data, dynamic video data or both picture data and video data; the receiving data source sends The HDR point screen data is analyzed to obtain the metadata corresponding to the HDR point screen data; when the HDR point screen data is image data, the obtained metadata is HDR Static Metadata; when...

Embodiment 2

[0083] This embodiment provides a device for detecting an HDR display module. The device can be implemented in software and / or hardware, and can be integrated on an electronic device.

[0084] figure 2 It is a logical block diagram of an HDR display module detection device provided in this embodiment, see figure 2 As shown, the device includes a control unit, a parsing unit, a cache unit and a data sending unit for detecting the HDR module;

[0085] Among them, the control unit is used to analyze and analyze the control instructions issued by the data source, and obtain the interface timing and data type required by the module to be tested;

[0086] The parsing unit is used to obtain and analyze the HDR point screen data provided by the data source to obtain metadata corresponding to the HDR point screen data; the HDR point screen data includes image data and / or video data;

[0087] According to the different data types required by the module to be tested, the HDR point sc...

Embodiment 3

[0106] This embodiment has the same logical structure as the HDR display module detection device provided in Embodiment 2, the difference is that the HDR display module detection device provided in this embodiment can automatically adapt to the HDR module and the SDR module; specifically:

[0107] The control command and picture data sent by the data source through the network port, the control command includes the interface timing and data type required by the module to be tested, and also includes the flag bit used to indicate the imaging type required by the module to be tested, the imaging The type is HDR or SDR;

[0108] The network port module receives the control command and picture data sent by the data source. When the flag points to SDR imaging, the picture data is SDR picture data; the network port module sends the control command to the control unit, and sends the SDR picture data to the data processing module ;

[0109] The control unit sends the control command ...

Abstract

The invention discloses an HDR display module detection method and device and electronic equipment, and relates to the technical field of panel display and testing. The method comprises the steps of analyzing a control instruction sent by a data source to obtain an interface time sequence and a data type required by a to-be-tested module; analyzing the HDR point screen data to obtain correspondingmetadata; wherein the HDR point screen data comprises picture data and / or video data; caching the HDR point screen data and the metadata corresponding to the HDR point screen data respectively, and reading the HDR point screen data and the metadata matched with the data type under the triggering of the control instruction; outputting the HDR point screen data and the metadata corresponding to theHDR point screen data to a to-be-tested module according to an interface time sequence. According to the invention, detection of the HDR module can be realized, detection of the SDR module can be compatible, imaging data matched with the to-be-detected module can be automatically output according to the imaging type of the to-be-detected module, and thus display modules of different imaging typescan be compatible and automatically adapted.

Description

technical field [0001] The invention belongs to the technical field of display and testing of display modules, and more particularly relates to a method, device and electronic equipment for testing HDR display modules. Background technique [0002] High Dynamic Range (HDR) imaging is used in computer graphics and cinematography to achieve a larger exposure dynamic range (that is, a greater difference between light and dark) than Standard Dynamic Range (SDR) imaging technology A technology, the purpose of HDR imaging is to correctly reflect the light and dark pictures of the real world. [0003] HDR Metadata is the metadata used as the carrier of HDR content parameters, and the display module needs to use this metadata when analyzing HDR data. At this stage, HDR Metadata includes HDR Static Metadata and HDR Dynamic Metadata. Static Metadata means that the display module maps HDR data in a fixed way for screen display, and Dynamic Metadata means that the display module can ma...
