Problems solved by technology

In actual application design, the greater the amount of moisture absorption deformation, the larger the gap that must be reserved between the display panel and the diffuser plate, thus increasing the thickness of the entire display element

Embodiment Construction

[0045] Fixing mechanism

[0046] FIG. 3A is a schematic diagram showing a fixing mechanism disposed on a backlight module according to a preferred embodiment of the present invention. Please also refer to Figure 3B, which is an enlarged schematic view showing the fixing mechanism in FIG. 3A. The backlight module of FIG. 3A includes a housing (Metal rear) 30, and the housing 30 has a housing (housing) 31 for placing a plurality of optical components (Back Light Components) (not shown) of the backlight module. The bottom surface of the housing 30 preferably has a reflector 32 . In the present invention, at least one fixing mechanism is arranged in the casing, and then the diffusion plate 36 is placed to reduce the deformation and warping of the diffusion plate 36 due to high temperature and moisture absorption. The fixing mechanism includes a supporting member 33 and an adhesive body (not shown). Such as Figure 3B As shown, the supporting member 33 has a pillar 331, and t...

Abstract

A fixing mechanism for preventing diffusion plate on back light module from warping consists of a supporting column, holding portion and fixing portion connected at two ends of said column separately and adhesive body set on holding portion of support column. It features that diffusion plate is set above holding portion of support column and is drawn on by sticking force of adhesive body.

Description

technical field [0001] The invention relates to a fixing mechanism arranged in a direct-type backlight module, and in particular to a fixing mechanism which can prevent the warping of the diffuser plate of the direct-type backlight module. Background technique [0002] Liquid Crystal Display (LCD) has been widely used in recent years because of its thin size, light weight, low power consumption, and no radiation pollution. A liquid crystal display (LCD) is assembled from a display unit, a backlight module, and a casing with a frame. The display unit includes a display panel (displ8y panel), a circuit board capable of processing data signals, and a supporting thin film package (Tape Carrier Package, TCP). [0003] The backlight module is located under the display unit to provide a uniform light source to the display unit of the LCD. The way of providing the light source can be divided into side-light type backlight module or direct-type backlight module. Generally speaking...
