Embodiment Construction

[0046] The invention is described below with reference to illustrative embodiments. Those skilled in the art will recognize that many alternative embodiments can be accomplished using the teachings of the present invention and that the invention is not limited to the exemplary embodiments which are described for explanatory purposed.

[0047] The invention uses an elastic member, which is made of, for example, silicone rubber and is triangular in shape, wherein the ends of the longitudinal cross-section are more pointed than the bottom. And, the elastic portion prevents the intrusion of dust without adversely affecting the display condition of the screen. In other words, the elastic member improves display quality, shock resistance, and impact resistance.

[0048] Exemplary embodiments of the present invention include the first to sixth embodiments. The first exemplary embodiment ( image 3 and Figure 4 ) is an example of placing an elastic member between the liquid crysta...

Abstract

An elastic member ( 3 b) is fixed to a space between a front surface of an intermediate frame ( 4 a) and a rear surface of a liquid crystal panel ( 2 ) constituting a liquid crystal display module ( 12 ), or a space between a rear surface of an upper frame ( 1 ) and the rear surface of the liquid crystal panel ( 2 ) constituting the liquid crystal display module ( 12 ). Alternatively, the elastic members ( 3 b) are fixed to both of the spaces. A peak portion ( 14 a) of the elastic member ( 3 b) is formed to possess a flexible structure. The liquid crystal display module is configured to hermetically seal the space between a back light ( 11 a) and the liquid crystal panel ( 2 ), the space between the upper frame ( 1 ) and the liquid crystal panel ( 2 ), or both of the spaces.

Description

technical field [0001] The invention relates to a liquid crystal display module and a backlight used for the module. More specifically, the present invention relates to a liquid crystal display module with a dustproof structure and a backlight for the module. Background technique [0002] For example, Japanese Unexamined Patent Publication No. 2003-005658 (pp. 2-3, image 3 and 5 ) has disclosed a display device configured to integrate a liquid crystal panel and an illumination panel to enhance the dustproof effect of the liquid crystal display module. [0003] The display device disclosed in this publication includes a display unit in which a constant space is maintained between a display panel and an illumination panel for illuminating the display panel by using a frame main body. The display unit is covered with a protective cover unit. Specifically, the frame body is made of flexible components, and a protrusion is integrally formed on the frame body to fill the space...
