Abstract

The invention relates to a measurer which is used to measure a reaction speed of a display panel. The measurer comprises a microcontroller and a photodetector. The microcontroller provides a control instruction so that a display controller of the display panel provides test frame data to the display panel according to the control instruction. The photodetector senses a test frame of the display panel corresponding to the test frame data and provides a corresponding sensing signal. The sensing signal is associated with brightness and a reaction signal. The reaction signal can be used to calculate the reaction speed of the display panel. Related methods are disclosed.

Description

technical field [0001] The present invention relates to a display panel response speed measuring device and a related measuring method, and in particular relates to a high-efficiency and low-cost display panel response speed measuring device and a related measuring method. Background technique [0002] Display panels, such as liquid crystal display panels, are the core components for audio-visual products such as monitors, monitors, and TVs to display images; audio-visual products are equipped with display controllers to provide image (picture frame or frame) data according to the content of the image to be displayed to the display panel to drive the display panel to present image images. In order to ensure the quality of image display, it is necessary to measure the characteristics of the display panel so that the display controller can compensate the characteristic defect of the display panel. Response time (response time) is a very important display panel characteristic....
