Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen module processing technology, and in particular to a rapid curing device for OLED screen modules. Background Technology
[0002] OLED screen modules, or Organic Light Emitting Diode screen modules, are an advanced display solution. They mainly consist of an OLED display screen, a PCB board, and a frame. The OLED display screen is the core component, possessing self-emissive properties and eliminating the need for a backlight required by traditional LCDs. Its working principle is based on an organic material coating and a glass substrate. When an electric charge passes through, the organic material emits light, and the color of the light emitted depends on the material of the organic light-emitting layer. Structurally, the bottom layer is the substrate, usually made of glass or flexible plastic, which provides support. Above it is the anode layer, often made of transparent and conductive indium tin oxide, which is responsible for injecting holes. Next are the crucial organic layers, including a hole injection layer, a transport layer, and an emissive layer, where electrons and holes combine to generate photons and emit light. The topmost cathode layer injects electrons to complete the circuit. To quickly cure the OLED screen module, a rapid curing device for OLED screen modules is required.
[0003] Currently available OLED screen module rapid curing devices mainly consist of a curing stage, a curing unit, and a clamping and fixing device. They are used in the adhesive curing stage of module production and are suitable for curing encapsulation adhesives and bonding adhesives. In the process of flexible OLED module encapsulation and screen-touch layer bonding, they rapidly cure adhesives through ultraviolet light or thermal radiation, shortening the production cycle, improving bonding strength and stability, ensuring module sealing performance and structural robustness, and meeting the needs of mass production. However, during long-term operation, the concentrated heat from the light source can easily damage OLED materials due to high temperatures, especially the plastic substrate of flexible modules, which is prone to deformation. To solve the above problems, existing technologies only integrate a microchannel water-cooling structure next to the light source module, combined with a graphene heat sink, to control the temperature within the OLED's tolerance range. However, they have not improved the screen module fixing structure, resulting in local over- or under-curing of the module, affecting the adhesive bonding strength, increasing the risk of delamination and light leakage, and failing to meet the usage requirements.
