Display module separation device and separation method

Abstract

The invention discloses a display module separation device and a separation method. A display module comprises a first part and a second part which are bonded through a bonding layer. The separation device comprises a first fixing platform, a second fixing platform, a laser cutting mechanism and a control mechanism; the first fixing platform and the second fixing platform are parallelly arranged in the opposite direction, and the display module is arranged between the first fixing platform and the second fixing platform; and the first part is fixed to the first fixing platform, and the secondpart is fixed to the second fixing platform; and the laser cutting mechanism is used for cutting the bonding layer so that the first part and the second part can be separated. The first part and the second part can be separated by cutting the bonding layer through laser, acting force is applied only to the bonding layer during cutting, the situation that the first part and / or the second part are / is broken after being stressed is avoided, the repair yield of the display module and the material utilization rate can be effectively increased, the display module separation device and the separationmethod are especially suitable for repair or remachining of the AMOLED display module, the cost is reduced, and the enterprise competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of display module rework, and more particularly relates to a display module separation device and a separation method. Background technique [0002] At present, in consumer fully bonded display products, the application of organic displays (such as AMOLED) is gradually increasing, and in the overall design of display products, organic displays are usually combined with optical glue and protective glass or touch screen panels. In the way of full lamination, when the lamination is out of position or damaged and it is necessary to separate the organic display screen from the protective glass or touch screen panel, the method used in the prior art is to cut the optical glue by metal wire cutting or cutting knife To achieve the purpose of separation, the application of this technology in LCD is still feasible, because the glass in LCD has good flexibility, but due to the process characteristics of organic display...

[0002] At present, in consumer fully bonded display products, the application of organic displays (such as AMOLED) is gradually increasing, and in the overall design of display products, organic displays are usually combined with optical glue and protective glass or touch screen panels. In the way of full lamination, when the lamination is out of position or damaged and it is necessary to separate the organic display screen from the protective glass or touch screen panel, the method used in the prior art is to cut the optical glue by metal wire cutting or cutting knife To achieve the purpose of separation, the application of this technology in LCD is still feasible, because the glass in LCD has good flexibility, but due to the process characteristics of organic display screens, the glass has high hardness, poor toughness, and fragility. The above separation method It is easy to cause the breakage or deformation of the organic display screen, resulting in a low repair yield rate, and the current organic display screen price is much more expensive than LCD, and the low repair yield rate will directly increase the production cost of the enterprise
