Description
Technical field
Field of liquid crystal panel display is the utility model is related to, more particularly to a kind of ultra-thin direct-type backlight flat panel Liquid Crystal is shown
Module.
Background technology
Liquid crystal display panel is to show image by thin film transistor (TFT) driving electrodes, itself does not shine, so being
The backlight that liquid crystal display panel provides all light sources plays highly important role, and the cost of backlight accounts for liquid crystal
Show the 30-50% of device, the electric power consumed more accounts for 75%, can say it is considerable component in liquid crystal display.According to backlight
The difference of the position of placement, backlight module can be divided into two kinds of direct-type backlight and side entrance back, when large-sized liquid crystal display
When device uses side-edge type backlight, cost and size, the weight of light guide plate are directly proportional, and the uniformity of area source and arrival liquid
The index such as brightness of crystalline substance screen can decline, and down straight aphototropism mode set due to light source directly vertically upward, light loss is small, with side entering type
Backlight module, which is compared, to be saved electric power and is increasing brightness and reduce and take advantage in cost, thus down straight aphototropism mode set into
The mainstream developed for the backlight of large scale liquid crystal display panel.
Although application of the down straight aphototropism mode set in large scale liquid crystal display is with the obvious advantage, its application there is also
Some defects, cause the liquid crystal display die set of current direct-type backlight more thick and heavy；Specifically include：1st, down straight aphototropism mode set

Diffuser plate and optical diaphragm be installed on the back plate openings end face that four side plates enclose, then in backlight light-emitting surface
Liquid crystal panel is simultaneously fixed on fixed frame by upper installation liquid crystal panel fixed frame, finally installs front frame in liquid crystal panel surface
It is fixedly connected with backboard, causes the gap of liquid crystal panel and light-emitting surface larger and complicated, heavy；2nd, for straight-down negative LED
Backlight module, module thickness indication are defined as mixed light height, at present needed for its backlight of down straight aphototropism mode set on the market
Light mixing distance is longer, adds the thickness of backing structure；And make since warpage easily occurs for the reflecting plate of conventional plastic material
Obtain it needs prearrangement of deformation amount wide arc gap between liquid crystal panel, further increases the thickness of the liquid crystal display die set of direct-type backlight
Degree；Since plastics diffuser plate is too soft, so wanting mounted array or diffuser plate to support post on backboard, picture can be influenced and form light
Point.3rd, the down straight aphototropism mode set of large scale liquid crystal display is intended to open large-scale metal stamping die for different sizes, opens
Mould expense is sufficiently expensive, then the chassis of the thick and heavy down straight aphototropism mode set of punching press iron plate making, chassis are gone to metal stamping die
Rust, plating, drilling, rivet, spraying etc. clearly are also carried out after shaping, complex process cost is expensive, and dimensional variations are all each time
Tool is re-molded, opening period length, causes the new-product development time to be grown, and mould increases, stamping parts stock increase.How not
Increase backlight cost, reduce power consumption, under energy-saving preceding topic, brightness is improved by new construction design, is improved out
The uniformity of light and to direct-type backlight liquid crystal module carry out be thinned loss of weight be research and development emphasis and difficult point.
The content of the invention
