Abstract

An embodiment of the invention provides a display screen flicker detecting device and method, relates to the field of display technology and is used for solve a problem of incapability of detection offlicker degree of multiple positions in a display screen at the same time. The device includes a sensor module used for collecting luminance data of different positions of a to-be-detected display screen in the same moment; a data processing module used for generating a flicker detecting result at least including a first flicker detection result used for indicating the flicker degree of the different positions of the to-be-detected display screen in the same moment according to the luminance data of the different positions of the to-be-detected display screen in the same moment; and a displaycontrol module used for outputting the flickering result to a display module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen flicker detection device and method. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display), as a flat panel display device, is more and more used in the field of high-performance display because of its small size, low power consumption, no radiation and relatively low production cost. among. [0003] Existing liquid crystal display devices are mostly driven by pixel polarity reversal, but since the absolute values ​​of the positive and negative pixel voltages are not completely symmetrical, the brightness of each frame of the picture will have periodic high and low changes, and the reaction is visually difficult. Flicker occurs; therefore, the degree of flicker is an important indicator for judging the quality of the display screen of a liquid crystal display, and the detection of the degree of flicker is generally performed by a co...
