Example Embodiment

[0021] In order to further illustrate the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0022] figure 2 It is a schematic diagram of a cross-sectional structure of an adhesive tape in an embodiment of the present invention. The adhesive tape is used for pasting between two objects to be pasted together. Such as figure 2 As shown, the adhesive tape 23 of the present invention includes an upper surface 231 and a lower surface 232, and both the upper surface 231 and the lower surface 232 are adhesive. Further, there is a closed cavity 233 between the upper surface 231 and the lower surface 232 of the tape 23, the cavity 233 extends along the length of the tape 23, and the cavity 233 is in a vacuum state. Since the cavity 233 is in a va...

Abstract

The invention provides an adhesive tape, a liquid crystal display module and a method for disassembling a liquid crystal display panel and a back light. The upper surface and the lower surface of the adhesive tape both have viscosity; an enclosed cavity is located between the upper surface and the lower surface of the adhesive tape and is in a vacuum state to allow the upper surface and the lower surface of the adhesive tape to stick close to each other; the upper surface and the lower surface of the adhesive tape are respectively adhered with two objects to be pasted; when the two objects are to be disassembled, the cavity is inflated, the volume of the cavity increases, the two objects are jacked up by the expanded adhesive tape, the upper surface and the lower surface of the adhesive tape form curved surfaces, sticking and contact areas respectively between the upper surface of the adhesive tape and one of the two objects and between the lower surface of the adhesive tape and the other of the two objects decrease, and the two objects are stripped from two sides of the adhesive tape to the center of the adhesive tape. According to the invention, the enclosed cavity is arranged in the adhesive tape, functions of the adhesive tape are changed through changing pressure intensity in the cavity, so the sticking function of the adhesive tape is not influenced while disassembling of the liquid crystal display panel and the back light is facilitated, which enables damage to the liquid crystal display panel in the process of disassembling to be avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an adhesive tape, a liquid crystal display module and a method for disassembling a liquid crystal panel and a backlight plate. Background technique [0002] With the rapid development of electronic products towards lightness, thinness and miniaturization, almost all kinds of portable electronic products use liquid crystal displays (Liquid Crystal Display, LCD) as display panels, especially in camcorders, notebook computers, desktops, etc. In products such as computers, smart TVs, mobile terminals or personal digital processors, liquid crystal displays are already an important component. [0003] A liquid crystal display module (Liquid Crystal Module, LCM) is an important component of a liquid crystal display. Such as figure 1 As shown, in the production process of the liquid crystal display module, the liquid crystal panel 11 and the backlight plate 12 of the liq...
