Problems solved by technology

However, during the lamination process of polarizers, foreign matter, air bubbles, and dirt are likely to occur. In this case, it is necessary to rework the defective products. 200' detach and reattach polarizer 300' see image 3 The traditional method of separating the polarizer 300' from the flexible OLED display panel 200' is to tear the polarizer 300' from the flexible OLED display panel 200' by external force. However, the flexible OLED display panel 200' is stacked by a multi-layer structure. As a result, the pull of external force is easy to cause poor peeling (Peeling) between the layers, and the success rate of separation is low, which increases the production cost

Embodiment Construction

[0032] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0033] see Figure 4 , the present invention provides a method for separating a polarizer and a flexible OLED display panel, comprising the following steps:

[0034] Step 1. Please refer to Figure 5 , providing mutually bonded polarizers 100 and flexible OLED display panels 200;

[0035] The polarizer 100 includes an adhesive layer 110 , a polarizing layer 120 , and a protective layer 130 sequentially arranged from bottom to top; the adhesive layer 110 is attached to the upper surface of the flexible OLED display panel 200 .

[0036] Specifically, the adhesive layer 110 is made of pressure sensitive adhesive.

[0037] Specifically, the polarizing layer 120 includes two layers of cellulose triacetate (TAC) and a layer of polyvinyl alcohol (...

Abstract

The invention provides a method for separating a polarizer from a flexible OLED display panel. Laser irradiation is carried out on an adhesive layer laminated on the flexible OLED display panel in the polarizer to carbonize the adhesive layer until loss of the viscosity, a polarizing layer and a protective layer of the polarizer can be conveniently stripped from the flexible OLED display panel, the carbonized adhesive layer on the flexible OLED display panel is cleaned, and separation of the polarizer and the flexible OLED display panel can be completed without relatively high external force, so that the success rate is high, poor striping caused by the stress among various layers of structures of the flexible OLED display panel in the separation process can be effectively prevented and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for separating a polarizer and a flexible OLED display panel. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, also known as organic electroluminescent display, is a new type of flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminance, Wide range of working temperature, light and thin size, fast response speed, easy to realize color display and large-screen display, easy to realize matching with integrated circuit driver, easy to realize flexible display, etc., so it has broad application prospects. [0003] According to the driving method, OLED can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor (ThinFilm Transistor, TFT) m...
