Abstract
The LCD includes one LCD panel, one frame and one optical membrane. The LCD panel is for display image; the frame for supporting the LCD panel has several lamp tubes for projecting light to the LCD panel and one runner; and the optical membrane is set inside the runner. The back light module of the present invention has enough thickness and strength and no need of supporting metal frame. In addition, the optical membrane is screwed inside the runner to reduce deformation.
Description
Technical field
The present invention relates to a kind of LCD and backlight module thereof, be meant a kind of LCD and backlight module thereof that chute is used to embed blooming piece that have especially.
Background technology
Along with the progress of electronics technology, the accompanied electronic product is in vogue especially in daily life, increases day by day for the demand of the display compact, that power consumption is low.LCD because have that power consumption is low, thermal value is few, advantage such as in light weight and non-light emitting type display, be often used in the above-mentioned electronic product, even progressively replace traditional cathode-ray tube display.Figure 1 shows that the structure of existing LCD.Generally speaking, LCD comprises that the middle panel of LCD 10, that is provided with liquid crystal material of a two substrates is disposed at the direct type backlight module 20 and the shell 11 of panel of LCD 10 belows.Direct type backlight module 20 configurations one light source, the light that light source sent is dispensed on the surface of liquid crystal panel 10 uniformly.With regard to large-sized LCD, direct type backlight module 20 has and is easy to make and advantage cheaply, is used widely.Direct type backlight module 20 comprises a shell 70, and shell 70 has one and is disposed at the reflector plate 60 of its lower surface and is positioned at the fluorescent tube such as cold-cathode tube 50 and a plurality of blooming piece 30 such as diffusion sheet and prismatic lens that is disposed on the shell 70 of its bottom.Fluorescent tube 50 compartment of terrains are disposed in the viewing area of panel of LCD 10.Because the fluorescent tube 50 as light source is line sources, the illumination on panel of LCD 10 is uneven.Therefore the blooming piece 30 that must dispose diffusion sheet and prismatic lens and so on is used to provide even planar light source between fluorescent tube 50 and panel of LCD 10.Multiple backlight module is provided in the prior art, had for example licensed to the 6407781B2 United States Patent (USP) of Kitada on June 18th, 2002 and licensed to people's such as Takemoto 6417833B1 United States Patent (USP) on July 9th, 2002.Backlight module 20 generally has a metal frame 40 in addition, is disposed at the front end of backlight module 20.Metal frame 40 normally with aluminium, stainless steel or galvanized steel plain sheet manufacturing, is used for fixing diffuser plate and blooming piece, is used to support panel of LCD simultaneously.For large-sized LCD, particularly greater than the size more than 30 inches, metal frame 40 will be difficult to the mat stamped, and need make in the mode of welding, but this manufacture is expensive and consuming time.
Summary of the invention
The objective of the invention is, a kind of LCD and backlight module thereof are provided, have bottom-lighting type back light module and and be used for fixing the blooming piece chute.
The objective of the invention is to realize: a kind of LCD and backlight module thereof by following technological means, comprise: one is used for panel of LCD, a framework and a blooming piece of show image, it is characterized in that: framework has a plurality of throw lights that are used for to panel of LCD and support the fluorescent tube and a chute of panel of LCD; Blooming piece is configured in the chute.
The blooming piece of described LCD and backlight module thereof by a plurality of bolt in chute.Be provided with a plurality of on the framework of described LCD and backlight module thereof in being used for that panel of LCD is fixed in set locational jut.Also be provided with a backboard on the framework.The inboard of backboard disposes a reflecting plate.
Another kind of LCD provided by the invention and backlight module thereof comprise: a main body, a projection, a plurality of fluorescent tube and a blooming piece is characterized in that: the profile of main body is a rectangle; The projection that is disposed on the main body constitutes a chute; A plurality of fluorescent tubes are disposed in the main body; Blooming piece is disposed in the chute.
The blooming piece of described LCD and backlight module thereof by a plurality of bolt in chute.The LCD of described LCD and backlight module thereof has a panel of LCD, and backlight module comprises that also a plurality of being disposed at is used on the projection panel of LCD is fixed in set locational jut.One backboard is set on the framework of described LCD and backlight module thereof, and the inboard of backboard is provided with a reflecting plate.
The invention has the advantages that:, therefore do not need metal frame to support backlight module 1, because the main body of LCD of the present invention and backlight module thereof has suitable thickness and intensity.2, blooming piece is in the sub-chute of nationality bolt, and LCD is normally upright in use, so blooming piece is hung on the bolt basically, but not stand on the framework, and this will help to improve the deflection of blooming piece.
