Problems solved by technology

However, it is difficult to remove the liquid crystal display panel after sticking it to the plastic frame or other parts by the first method, which brings great difficulties to manufacturing and heavy work; and it is difficult to effectively fix the liquid crystal display panel by the second method. Accurately control the expansion and contraction of LCD panels and acrylic panels, which can easily lead to broken LCD panels

Abstract

The invention discloses a liquid crystal display device and a rubber frame thereof. The liquid crystal display device comprises the rubber frame, a back plate, an optical plate, at least one optical diaphragm and a liquid crystal display panel, wherein the optical plate is arranged on the back plate, the optical diaphragm is arranged on the optical plate, the rubber frame is fixedly connected with the back plate, and the optical diaphragm is fixedly pressed by the rubber frame so as to fix the optical plate and the optical diaphragm. The rubber frame comprises at least one rim and a plurality of vacuum absorption pipes, wherein first ports of the vacuum absorption pipes are arranged on the rims, the liquid crystal display panel is arranged on the rims and covers the first ports, and air in the vacuum absorption pipes are extracted from second ports of the vacuum absorption pipes so as to enable the liquid crystal display panel to be absorbed and fixed. The liquid crystal display device enables the liquid crystal display panel to be absorbed and fixed through the vacuum absorption pipes arranged on the rubber frame, is free of frame, simple in absorption operation and not prone to break when the liquid crystal display panel is expanded or contracted, and improves process yield and competitiveness of products.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display. More specifically, it relates to a liquid crystal display device and its plastic frame. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as light weight, thin body, power saving, etc., and thus has been widely used. Most of the existing liquid crystal display devices are backlight liquid crystal display devices, which include a backlight module, a liquid crystal display panel and a frame, wherein the frame is fixedly connected to the backlight module to fix the liquid crystal display panel on the backlight module, and the backlight The module provides a light source with uniform brightness to the liquid crystal display panel, so that the liquid crystal display panel displays images. [0003] However, with the continuous development of production technology of liquid crystal display devices, frameless design has become a...
