Problems solved by technology

[0004] However, the locking screw hole of the front frame is very close to the polarizing film. If the locking device shakes or slides obliquely due to careless use, and the polarizing film is extremely thin, the tip of the locking device will easily scratch the polarizing film, causing the The whole film is scrapped

Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in further detail below with reference to the accompanying drawings. Throughout the description, like reference numerals refer to like parts.

[0020] Figure 1a A schematic diagram of a locking device kit is shown. refer to Figure 1a , the locking device kit includes: an integral component 100 of a sleeve and an insulating rod, a sleeve 101 , an insulating rod 102 , elastic terminals 103 and nylon cable ties 104 . Wherein, the sleeve 101 and the insulating rod 102 are fixedly connected, for example, integrally formed. The end of the insulating rod 102 away from the sleeve 101 and the elastic terminal 103 are fixedly connected with a nylon cable tie 104. The insulating rod 102 is made of a cylindrical plastic material, and the elastic terminal 103 can be a rubber strip, a plastic strip, etc. Elastic material.

Abstract

The invention provides a polarizing film locking unit on a front frame of a liquid crystal display, which is applicable to preventing the locking device from damaging the polarizing film of a liquid crystal display panel module while assembling the liquid crystal display panel module by using the locking device. The locking device unit comprises an integral member of a sleeve and an insulating rod and an elastic terminal, wherein the integral member of the sleeve and the insulating rod is sleeved on the locking device through the sleeve; the elastic terminal is arranged at the tail end of the insulating rod. When the locking device unit is arranged on the locking device, the tail end of the insulating rod exceeds one end of the locking device which is used for locking screws. In the locking unit of the invention, when the liquid crystal display panel module is assembled, the locking device vibrates or obliquely slips, and the tail end of the insulating rod in the locking device unit arranged on the locking device exceeds one end for locking the screws of the locking device,, which can provide the function of horizontally limiting, and has supporting action to rapidly adjust the position of the locking device to ensure that the top end of the locking device returns to an accurate operating point. Thus, the top end is prevented from scratching the polarizing film.

Description

technical field [0001] The invention relates to the assembly of liquid crystal display panel modules, in particular to a protective device used to avoid damage to the polarizing film on the liquid crystal display panel during the assembly of the front frame and the liquid crystal display panel. Background technique [0002] Currently, in the assembly of the liquid crystal display panel module, the fixing between the front frame and the liquid crystal display panel is involved. The front frame is generally a metal or plastic frame, which is used to protect the edges of the liquid crystal display, prevent the impact of electrostatic discharge and reinforce the structure of the liquid crystal display. The liquid crystal display panel has polarizers above and below. Polarizer, also called polarizing film, is an optical film that only allows light in a certain polarization direction to pass through, and is an optical element that converts natural light into polarized light.
