Polarization plate, screen module group and manufacturing method of the screen module group

Abstract

The polarizing plate, the screen module and the preparation method of the screen module provided by the present invention relate to the field of semiconductor device manufacturing, all of which can be based on the traditional structure of the screen module, by arranging the adhesive layer between the polarizing plate and the protective film Even if the polarizer is directly attached to the touch panel, it can not only minimize the pollution damage to the device structure during the manufacturing process, but also facilitate visual inspection, so that the contaminated device structure can be found in time to continue Subsequent rework operation; In addition, in the above-mentioned rework operation process, the thicker optical adhesive layer is generally separated, and since the polarizer is attached to the touch panel during the separation operation, It can effectively protect the touch sensor on the touch panel from damage, thereby effectively improving the efficiency of heavy industrial operations and greatly reducing production costs.

Description

technical field [0001] The invention relates to the field of semiconductor device manufacturing, in particular to a polarizing plate, a screen module and a method for preparing the screen module. Background technique [0002] At present, in the manufacturing process of display devices (such as AMOLED display devices, etc.), it is generally necessary to attach a polarizer on the cover glass of the panel (Panel) to form a screen module. [0003] figure 1 It is a schematic structural diagram of a traditional screen module; figure 1 As shown, a conventional display module generally includes a sandwich structure composed of a polarizer 11, an optical clear adhesive (OCA for short) 12 and a touch panel (TP for short) 13, and the optical clear adhesive 12 is disposed on Between the polarizer 11 and the touch screen 13 , that is, the optical adhesive layer 12 is directly attached to the surface of the touch screen 13 . [0004] However, since the thickness of the optical adhesive...

[0004] However, since the thickness of the optical adhesive layer 12 (about 0.12-0.15 mm) is much greater than the thickness of the adhesive layer in the polarizer 12 (about 0.01-0.03 mm); therefore, when the screen module needs to be reworked, it will Choosing to peel off the optical adhesive layer 12 will easily cause damage to the touch sensor (Touch Sensor) on the touch screen 13, and even cause the entire touch screen 13 to be scrapped

[0005] In addition, the defect rate of the current TP full lamination technology is very high, that is, there are many reworked products, and because the OCA and the touch sensor on the TP will be in direct contact, the touch sensor will be unprotected when the bad rework is separated, which is extremely difficult. It is easy to cause TP to be scrapped, which greatly increases the cost of production
