Problems solved by technology

[0004] However, Mura, a phenomenon in which the uneven brightness of the display causes various traces, affects the display taste of the display panel and the visual experience of the user.
When the display panel is abnormal in a large area, it takes a lot of time to shoot and measure, and manual focus often produces errors, especially for areas with extremely small brightness abnormalities that are not easy to find and overcome

Abstract

The invention discloses a detecting method and device of a display panel. The detecting method comprises the steps that the display panel is continuously shot in a scanning mode, and original images are collected; the collected original images are subjected to preprocessing so as to obtain to-be-detected images; the to-be-detected images are detected, and detection results are output. Because abnormal areas in the display panel are automatically detected while the display panel is panoramically scanned, the abnormality measuring time can be reduced, the requirements for wide-range detection of the abnormal areas are met, the measurement is accurate, the detecting method and system are convenient to use, and the display quality of the display panel and the visual experience of a user can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a detection method and a detection device of a display panel. Background technique [0002] Liquid crystal displays have many advantages such as thin body, power saving, and no radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power consumption, e...
