Problems solved by technology

Therefore, when the inspection fixture performs the quality inspection of the display panel before leaving the factory, it needs to occupy the resources of the signal generator for a long time, and the inspection time needs to be manually controlled, which will lead to low inspection efficiency and occupy human resources.

Abstract

The invention discloses a tooling fixture for detecting a display panel and a detection method thereof. The reading module of the tooling fixture is used to read the picture information that needs to be output when the tooling fixture detects the display panel; the control module is used for according to The picture information generates a corresponding data signal for driving the display panel to be detected for display and outputs it to the distribution module; the distribution module is used for distributing the data signal to at least one display panel to be detected for display. In this way, the tooling fixture of the present invention can generate a data signal for detecting the display panel according to the read picture information, that is, it can generate a detection picture by itself, and does not need to occupy signal generation resources compared with the prior art; and the data signal is transmitted through the distribution module. It is distributed to multiple display panels to be tested to drive the display panels to display and complete the quality inspection of the display panels before leaving the factory, so that multiple display panels can be tested at the same time, which greatly improves the detection efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a tooling fixture for testing a display panel and a testing method thereof. Background technique [0002] At present, display technology is widely used in the display of televisions, mobile phones, and public information, and the flat panel display used for displaying pictures is vigorously promoted because of its advantages of ultra-thin and energy-saving. [0003] However, display panels need to undergo quality inspection before leaving the factory, and some military display panels have a more stringent inspection environment and a longer period of time. Detection fixtures in the prior art such as figure 1 As shown, it includes: a signal generator and a driver board; the detection fixture is a one-to-one detection, the detection efficiency is relatively slow, and the detection time needs to be controlled artificially. Therefore, when the inspection fixture performs the quali...
