Problems solved by technology

[0003] However, in the process of lighting detection for high-PPI panels, due to the fact that the product pixels are getting smaller and thinner, the alignment accuracy is required to be within 2 μm, and the defect detection also requires a larger inspection angle of up, down, left, and right. For special defects such as color moiré (Mura), it must be found in the case of defective product comparison inspection, and the detection equipment used before is very easy to cause damage to the panel and probe caused by the operation, which greatly restricts the high-quality The yield rate of PPI products affects the design and production of subsequent products

Abstract

The invention provides a detection jig, which comprises a carrying table and a testing signal output device. The detection jig is characterized by also comprising a position adjusting mechanism, wherein the position adjusting mechanism is used for adjusting an inclining angle of the carrying table, the carrying table comprises a plurality of carrying parts, each carrying part is used for carrying a to-be-detected display panel which is arranged on the corresponding carrying part, and the testing signal output device is used for respectively providing testing signals for a plurality of display panels which are arranged on the corresponding carrying parts. The detection jig is suitable for detecting the high-PPI (pixel per inch) display panels.

Description

technical field [0001] The present invention relates to the field of manufacturing display devices, in particular to a testing jig for testing display panels. Background technique [0002] In the flat panel display manufacturing process, in order to quickly and accurately check the product's adverse reaction to the production situation, a panel inspection station is set up in the production line. The general panel inspection engineering inspection is placed after the cutting process, and the probe unit in the special inspection equipment is used to perform probe testing on the panel. Probe test includes open test and color test for panel data lines and gate lines, targeting a single pixel. Use the probe unit to input display signals to the terminal area to detect defects. [0003] However, in the process of lighting detection for high-PPI panels, due to the fact that the product pixels are getting smaller and thinner, the alignment accuracy is required to be within 2 μm, a...
