Problems solved by technology

Currently, there is no way to measure the image display response time performance of the display system. It is only judged by whether the response of the mouse is smooth, and it is impossible to evaluate whether the display response of different images can meet the diagnostic requirements.

Embodiment 1

[0064] The present embodiment provides a method for testing the response time of a liquid crystal display system, comprising the following steps:

[0065] Get the refresh rate of the LCD system;

[0066] Generate a test image set according to the refresh rate and control the playback of the test image set;

[0067] Collect the image information of the image playback process of the liquid crystal display system;

[0068] The response time of the liquid crystal display system is acquired according to the image information of the image playing process of the liquid crystal display system.

[0069] Specifically, the method for obtaining the refresh rate of the liquid crystal display system includes: obtaining the refresh rate by invoking a system parameter obtaining interface through application software connected to the liquid crystal display system.

[0070] Specifically, the method for generating the test image set according to the refresh rate and controlling the playback of...

Embodiment 2

[0109] This embodiment provides a device for testing the response time of a liquid crystal display system, such as Figure 5 As shown, the device achieves the purpose of the present invention through the following major modules:

[0110] (1) Frame rate identification and control module: The frame rate identification and control module is used to identify and obtain the refresh rate of the graphics card, and the refresh rate value is used as the frame rate and image frame number of the test image playback, which is used to generate the test image set. The input of the playback module generates images of the corresponding number of frames and controls the playback of the images.

[0111] (2) Test image set generation and playback module: generate a test image set according to the frame rate obtained by the frame rate identification and control module.

[0112](3) High-frequency image acquisition module: The high-frequency image acquisition module collects the images generated b...

Embodiment 3

[0140] The embodiment of the present invention also provides a device for testing the response time of a liquid crystal display system, including a processor and a storage medium;

[0141] the storage medium is used for storing instructions;

[0142] The processor is configured to operate according to the instructions to perform the steps of the method according to the first embodiment:

[0143] Get the refresh rate of the LCD system;

[0144] Generate a test image set according to the refresh rate and control the playback of the test image set;

[0145] Collect the image information of the image playback process of the liquid crystal display system;

[0146] The response time of the liquid crystal display system is acquired according to the image information of the image playing process of the liquid crystal display system.

[0147] As will be appreciated by those skilled in the art, the embodiments of the present application may be provided as a method, a system, or a com...

Abstract

The invention provides a method and a device for testing the response time of a liquid crystal display system, which can accurately and systematically evaluate the response time of the liquid crystal display system when different image contents change under different image refresh rates. The method comprises the following steps: acquiring the refresh rate of the liquid crystal display system; generating a test image set according to the refresh rate and controlling playing of the test image set; collecting image information of an image playing process of the liquid crystal display system; and obtaining the response time of the liquid crystal display system according to the image information in the image playing process of the liquid crystal display system.

Description

technical field [0001] The invention relates to a method and a device for testing the response time of a liquid crystal display system, belonging to the technical field of liquid crystal display. Background technique [0002] In the field of medical image display, there are high requirements for the response time of image display, such as DSA and dynamic images of endoscopic surgery. At the same time, in the field of radiology reading, with the application of high-resolution systems, the response time of the display system is more important. The response time will lead to the poor fluency of the doctor's use of PACS to retrieve the image set and the poor timeliness of the mouse response, which seriously affects the customer's trial. reflect. [0003] Display products have various refresh rates and various panels. The combination of different refresh rates and different panels will produce characteristic display response characteristics, and the final response time will vary...
