Problems solved by technology

Before SMT packaging LEDs, the backplane can only use Automated Optical Inspection (AOI), and cannot perform Cell test inspection. Due to design reasons, there is a risk of missing inspections for the detection and location of short circuits at cross-lines, which greatly affects Production Yield and Reliability

Abstract

The invention discloses a display panel detection device. The display panel detection device comprises a mounting table; a display panel fixing assembly, arranged on the mounting table, and the display panel fixing assembly positioning a display panel and being horizontally arranged on the mounting table; a moving assembly, comprising a translation movable frame which is connected to the horizontal table surface of the mounting table in a sliding fit manner; and a detection assembly, installed on the translation movable frame, the detection assembly comprising at least one detection part, and the detection part being in electric contact with the display panel to detect whether the display panel is abnormal or not. The display panel detection device comprises a movable electrical detection mechanism which is used for detecting the short circuit / open circuit and the occurrence position of the short circuit / open circuit, so that the defective detection rate of the back plate of the display panel in the manufacturing process is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel detection device. Background technique [0002] In recent years, the application of mini LEDs as backlights in Liquid Crystal Display (LCD) panels can significantly improve display quality such as contrast and brightness, and has attracted more and more attention from the LCD market. The mini LED backlight technology is to bond the LED chip to the backplane with the drive circuit, and control the LED partition to emit light through the drive circuit to realize the dynamic backlight. Equipped with this backlight technology, LCD can achieve display quality with thinner appearance, higher brightness and super contrast. [0003] At present, LCD manufacturers realize the mini LED display technology by making the drive backplane required by mini LED through mature backplane technology, and then sending the backplane to the LED printing factory for LED bonding, and fin...
