Device for repairing defects of flexible OLED display device

Abstract

The invention relates to a device for repairing defects of a flexible OLED display device. The device comprises a display panel alignment mechanism, a movement mechanism, a laser repairing mechanism,an OLED lighting mechanism and a control mechanism, the display panel alignment mechanism is provided with a UVW console used for adjusting an alignment angle; the OLED lighting mechanism is providedwith a lighting control unit and an air suction needle pressing unit used for adsorbing and fixing a to-be-repaired workpiece to, the lighting control unit is electrically connected with the air suction needle pressing unit, and the air suction needle pressing unit is fixed to the UVW console; the movement mechanism is provided with a displacement table movement unit and a gantry movement unit, the laser repairing mechanism is arranged on a gantry movement unit, and the UVW console is arranged on the displacement table movement unit. A placing position and angle of the to-be-repaired workpieceare accurately controlled through the movement mechanism and the display panel alignment mechanism, the defect positioning and repairing precision of the to-be-repaired workpiece is better, defects can be completely repaired, and the repairing efficiency and the repairing quality are improved.

Description

technical field [0001] The invention relates to the technical field of display device repair, in particular to a device for repairing defects of flexible OLED display devices. Background technique [0002] OLED-Organic Light-Emitting Diode (OLED-Organic Light-Emitting Diode) display technology represented by flexible display is becoming more and more common, and has gradually become a new star of display panels. It is most noticeable in products such as mobile phones, media players and small entry-level TVs. Different from standard liquid crystal displays, OLED display technology has many advantages such as self-luminous technology without backlight, higher contrast, better image quality, thinner overall thickness and bendability, coupled with the continuous reduction of cost and the continuous increase of yield rate , it can be said that OLED display technology has already occupied half of the display market. With the increasing size and higher resolution of display panel...

AI Technical Summary

Problems solved by technology

At present, the net profit of panel manufacturers is usually less than 10%, and every 1% increase in yield means an increase in profit growth of nearly 10%

[0005] In the existing technology, the defects of flexible OLED display devices are usually repaired by laser, which can solve the purpose of repair and real-time detection, but the current automatic repair process is complicated, low in efficiency, and high in cost, especially the one-time repair success rate is low
