Problems solved by technology

However, during the operation of assembling the plastic frame after the expansion sheet is assembled, due to the existence of the bump 13, it is easy to lift the expansion sheet when the diaphragm is pressed, resulting in deformation of the expansion sheet and WAVING phenomenon in the finished product

Embodiment

[0013] A kind of liquid crystal display rubber frame of the present embodiment, such as figure 2 with image 3 As shown, it includes a frame-shaped plastic frame body 1. A number of vertically inwardly extending ribs 2 are provided on the inner side of a frame of the plastic frame body 1, and each rib 2 is provided with a protrusion on one side of the plastic frame body 1. Block 3, the side of the bump 3 facing the plastic frame body 2 is a slope with an inverted C angle.

[0014] In this embodiment, the ribs of the rubber frame of the liquid crystal display are designed as an inclined surface with an inverted C angle. This inclined surface can have a slope surface when the diaphragm is pressed, so that it will not interfere with the expansion sheet during assembly, and the expansion sheet will be lifted. It caused expansion deformation and WAVING phenomenon in the finished product, and the defect rate was improved from 1.58% before the design change to 0.

Abstract

The invention discloses a rubber frame of a liquid crystal display, and the rubber frame comprises a frame-shaped rubber frame body, wherein at least one vertically inward extending rib is arranged inside a border of the rubber frame body; a lug is arranged on one side wall, opposite to the rubber frame body, of each rib; and the side wall, opposite to the rubber frame body, of the lug is a slope with a reverse C-shaped angle. In the invention, the rib of the rubber frame for the liquid crystal display is designed into the slope with the reverse C-shaped angle, so that a slope surface exists during a diaphragm covering process, and during an assembling process, the rib is free from interfering an expanding piece, jacking the expanding piece, causing the expanding piece to deform and causing a WAVING phenomenon of an end product.

Description

technical field [0001] The invention relates to a plastic product, in particular to a plastic frame for fixedly installing optical parts in a backlight module. Background technique [0002] At present, liquid crystal display devices have the characteristics of light weight, thin thickness, low power consumption and low radiation, and have been widely used in information technology, multimedia technology and other fields, and gradually become the mainstream of various display devices. Generally, a liquid crystal display includes a display panel for image display and a backlight module for providing planar light to the display panel, and uses a metal frame and a plastic frame to accommodate and fix the display panel and the Backlight module. In the existing technology, such as figure 1 As shown, the plastic frame is a frame-shaped frame 11, and the inside of the frame of the frame-shaped frame 11 is provided with several vertically inwardly extending ribs 12, and a protrusio...
