Abstract

The invention discloses a detecting device and detecting method for a display panel. The detecting device comprises a detecting module, a power supply module, a data control module and a switching signal generating module. When a signal that is received by the data control module and is generated by the switching signal generating module is a first enabling signal, the data control module controlsthe output data interface to be in a high impedance state. Therefore, power-off turning off of the detecting device is not needed; the time of the whole system of the detecting device for power-off turning off and display panel restarting is saved while the panel is replaced normally and the panel is protected from being burned by short circuit. The production efficiency is improved and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a detection device and a detection method 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, the main component of the liquid crystal display is a display panel. The production of the display panel is complicated. During the production of the ...
