Organic light-emitting diode (OLED) display and method for coating polarizing film of OLED display

Abstract

The embodiment of the invention discloses a method for coating a polarizing film of an organic light-emitting diode (OLED) display. The OLED display comprises an OLED device. The method mainly comprises the following steps of: coating an adhesive on the surface of the polarizing film; attaching the surface of the polarizing film, on which the adhesive is coated, to the OLED device; and heating or irradiating the adhesive, so the polarizing film is tightly attached to the OLED device. The embodiment of the invention also discloses the OLED display. The method and the OLED display have the advantages that bubbles can be prevented from being generated in a polarizing film coating process, and the yield of the polarizing film coating process is improved.

Description

technical field [0001] The invention relates to the technical field of polarizer cladding, in particular to an organic electroluminescent diode display and a polarizer cladding method thereof. Background technique [0002] OLED (Organic Light Emitting Diode) displays need to vapor-deposit a layer of metal electrodes on the light-emitting surface to form diodes. However, this layer of metal will cause users to be affected by external light reflection when viewing OLED displays, which will reduce the contrast. Affects the viewing quality, especially under strong light or outdoors, so whether it is a top-emitting or bottom-emitting AMOLED display, it is necessary to attach a polarizer to block the reflection of external light. [0003] In the prior art, the method of pasting the polarizer is to first make the adhesive layer on the polarizer, and then attach the adhesive layer to the organic electroluminescent diode device. However, this method of pasting the polarizer is easy ...

[0003] In the prior art, the method of pasting the polarizer is to first make the adhesive layer on the polarizer, and then attach the adhesive layer to the organic electroluminescent diode device. However, this method of pasting the polarizer is easy Bubbles are generated between organic electroluminescent diode devices, especially when the substrate is a flexible substrate. Because the softness of the flexible substrate and the polarizer is different, bubbles are more likely to be generated during bonding, resulting in a very low yield rate in the polarizer process.
