Problems solved by technology
[0005] However, the fixing of the masking tape is not firm, and the protective hard film will slide slightly relative to the LCD panel module, so that in the subsequent tests, whether it is the aging test of the LCD panel module, pixel detection, In the test steps such as polarizer detection, the protective hard film must be torn off for testing and then put back on the protective hard film
This not only increases a lot of time and manpower consumption, but also increases the chances of the polarizer being damaged and dust particles falling on the polarizer
Moreover, repeatedly tearing and pasting the protective hard film will directly affect the final quality of the LCD panel module.

Embodiment Construction
[0026] The embodiment of the present invention will cooperate with Figure 2 to Figure 3 A detailed description is as follows. Please refer first figure 2 The schematic diagram shows a top view of the protective hard film of the liquid crystal display panel module of the present invention.
[0027] Such as figure 2 As shown, the protective hard film 200 of the liquid crystal display panel module includes a body 202, a flange 204, two first adhesive layers 206 and a second adhesive layer 208 arranged on the body 202, and two layers covering the first adhesive layer. Release layers 210 and 212 on layer 206 and second adhesive layer 208. The main body 202 has a first side 224 and a second side 225 located on the opposite side of the first side 224. In this embodiment, the first adhesive layer 206 and the second adhesive layer 208 may be double-sided adhesive tapes, and the release layers 210 and 212 may be release paper. In other embodiments of the present invention, the first ...

The invention discloses a protective hard film of a liquid crystal display panel mould, which comprises a protective hard film body, a flange, a first adhesion layer, a second adhesion layer and a releasing layer. The shape of the protective hard film body corresponds to and slightly larger than that of a liquid crystal display panel, and the protective hard film body is provided with a first side edge and a second edge which is positioned at the opposite side of the first side edge. The flange extends outwards from the second side edge of the protective hard film body, and the length of the flange is less then that of the second side edge. The first adhesion layer is arranged on the lower surface of the first side edge, and the length of the first adhesion layer is approximatively equal to that of the first side edge. The second adhesion layer is arranged on the lower surface of the second side edge at which the flange is arranged, and the length of the second adhesion layer is slightly more than, or equal to ,or slightly less than that of the flange. The releasing layer covers over the adhesion layers, and the length of the releasing layer is equal to or more than that of the adhesion layers, and one end of the releasing layer extends out of the adhesion layers. The invention relates to a liquid crystal display panel mould and a use method of the protective hard film thereof.
Description
【Technical Field】 [0001] The present invention relates to a protective hard film, in particular to a protective hard film suitable for liquid crystal display panel modules. 【Background technique】 [0002] Liquid crystal displays have the characteristics of light and thin appearance, low power consumption and no radiation pollution. They have been widely used in portable information products such as notebooks and personal digital assistants (PDAs), and have replaced traditional CRTs. The monitor has become a mainstream product. [0003] Generally speaking, the liquid crystal display includes a liquid crystal display panel module and a backlight module. The liquid crystal display panel module is assembled by the liquid crystal display panel, frame and various components. The upper and lower sides of the liquid crystal display panel each include an upper polarizer and a lower polarizer. The backlight module is arranged on the lower side of the lower polarizer. The backlight module...
