Problems solved by technology

Based on this, it can be seen that no matter what kind of specification it is, it takes time to edit a large number of grayscale display images before testing the response time, which consumes too much time and cost, and the test steps are cumbersome, so the measurement speed is slow and time-consuming too long

Abstract

The invention provides a response time testing method and a response time testing device, relating to the technical field of display. The testing method comprises the following steps: displaying a testing screen, wherein the testing screen comprises a testing background and a testing pattern moving on the testing background; and acquiring a smearing length of the testing pattern on the testing background, and evaluating the response time of a display device according to the smearing length of the testing pattern, wherein the testing background and the testing pattern on the testing backgroundhave different gray scales. By adopting the response time testing method and the response time testing device, measurement on response time can be rapidly and conveniently achieved.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a response time testing method and testing device. Background technique [0002] With the development of optical technology and semiconductor technology, flat-panel displays represented by Liquid Crystal Display (LCD) have the advantages of thinness, lightness, low power consumption, no radiation, good color purity, and high contrast, and have occupied an important position in the display field. leading position. The widespread use of liquid crystal displays has drawn increasing attention to their performance, such as response time. Among them, fast response is to require that when the external voltage signal of the liquid crystal display changes, each pixel can respond quickly so that the liquid crystal molecules can rotate to the corresponding position, thereby displaying the corresponding brightness and picture. [0003] The response time specified by the liquid cr...
