Abstract
A reworking apparatus for a display module includes a chamber and a temperature control unit. The temperature control unit controls a temperature in the chamber to reduce an adhesive property of an adhesive material of the display module. The adhesive material couples a first layer of the display module to a second layer of the display module. A stage is disposed in the chamber and holds the display module. A separation unit is disposed in the chamber and is inserted in between first and second layers of the display module. A movement unit moves the separation unit.
Claims28
A display module reworking apparatus, comprising:
- a chamber;
- a temperature control unit, wherein the temperature control unit is configured to control a temperature in the chamber to reduce an adhesive property of an adhesive material of the display module, the adhesive material coupling a first layer of the display module to a second layer of the display module disposed on the first layer;
- a stage disposed in the chamber, the stage configured to support the display module;
- a separation unit disposed in the chamber, the separation unit configured to be inserted in between the first layer and the second layer, wherein the separation unit comprises a separation knife having a quadrangular pyramid shape and first and second separation frames disposed at opposite sides of the separation knife;
- and
- a movement unit connected to the separation unit, the movement unit configured to move the separation unit inserted in between the first layer and the second layer to separate the second layer from the first layer,
- wherein the adhesive material has a first adhesive force in a first temperature and a second adhesive force which is lower than the first adhesive force in a second temperature, and wherein the temperature control unit changes the temperature in the chamber from the first temperature to the second temperature.
A reworking method for a display module, comprising:
- fixing a display module comprising a first layer and a second layer disposed on the first layer and coupled to the first layer, using an adhesive material, to a stage;
- controlling a process temperature to decrease an adhesive property of the adhesive material;
- inserting a separation unit in between the first layer and the second layer, wherein the separation unit comprises a separation knife having a quadrangular pyramid shape and first and second separation frames disposed at opposite sides of the separation knife;
- and
- moving the first and second separation frames after the separation knife is inserted in between the first layer and the second layer to separate the second layer from the first layer,
- wherein the adhesive material has a first adhesive force in a first temperature and a second adhesive force which is lower than the first adhesive force in a second temperature, and wherein a temperature control unit changes the temperature in the chamber from the first temperature to the second temperature.
