Problems solved by technology

For example, each support member 17 represents an increase in manufacturing cost and production time, and as the size of the liquid crystal display panel and the backlight module 1 are different, the height H from the back plate 11 to the optical film group 15 is also different (see figure 2 ), so the support 17 of the backlight module 1 of different sizes cannot be shared, and the height of the new support 17 needs to be redesigned, so the raw material compatibility of the support 17 is reduced, so the manufacturing cost will be increased, especially the optical grade The polycarbonate material is a high-cost material, and a large amount of use will increase the manufacturing cost

Embodiment Construction

[0021] Hereinafter, a backplane, a backlight module, and a liquid crystal display device according to preferred embodiments of the present invention will be described with reference to related drawings, in which the same components will be described with the same reference numerals.

[0022] Please refer to image 3 As shown, a backplane 2 according to a preferred embodiment of the present invention includes a backplane body 21 and a plurality of protrusions 22. The backplane body 21 has a plurality of holes 211, and each protrusion 22 is correspondingly disposed in each hole 211. , And form an angle with the back plate body 21. In this embodiment, the material of the back plate 2 is metal, such as aluminum or aluminum alloy, to facilitate heat conduction and heat dissipation. In addition, the surface of the back plate 2 can also be a galvanized steel sheet to resist oxidation. It should be noted that the backplane body 21 of this embodiment is substantially flat, but not limited...

Abstract

An LCD apparatus comprises a backlight module and an LCD panel which is adjacent to the backlight module that includes a backplane and an optical plate. The backplane comprises a backplane body and a projecting part and the backplane body is provided with a hole and the projecting part is arranged around the edge of the hole to form a certain angel with the backplane body. One end of the projecting part which is far away from the hole clings to the optical backplane.

Description

Technical field [0001] The invention relates to a back plate, a backlight module and a liquid crystal display device, and more particularly to a back plate, a backlight module and a liquid crystal display device having a convex portion to support an optical film. Background technique [0002] Liquid Crystal Display (LCD) has been used in a variety of electronic products due to its low power consumption, low heat generation, light weight, and non-radiation properties, and has gradually replaced traditional Cathode Ray Tube Display (CRT Display). [0003] Generally speaking, the liquid crystal display device includes a liquid crystal display panel (LCD Panel) and a backlight module (Backlight Module). Among them, the liquid crystal display panel mainly has two substrates and a liquid crystal layer sandwiched between the two substrates; and the backlight module can evenly distribute light from a light source to the liquid crystal display panel. [0004] Please refer to figure 1 , Whic...
