Problems solved by technology

[0005] In the prior art, when the liquid crystal panel is subjected to high-temperature and high-humidity tests, multiple external test circuit boards are required to provide images and clock signals. The external test circuit boards have poor performance in high-temperature and high-humidity resistance. The external test circuit board is easily damaged

Abstract

The invention discloses a display panel detection method and a display panel detection device. The detection method comprises the following steps: storing an image for detection in a source driver circuit board of a display panel; directly and electrically connecting a power board generating a power signal to the source driver circuit board; and transmitting the power signal and a clock signal to the source driver circuit board. The equipment investment cost and maintenance cost in the process of detection are saved. The number of working procedures in the process of detection is reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a detection method of a display panel 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 (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 fie...
