Abstract
The utility model provides a lateral ultra-thin LED backlight achieving device. A liquid crystal display panel, a first diffusion plate, a brightening plate, a backlight supporting frame, a light reflecting plate with an arc line, an LED array placed laterally and a backing plate are sequentially arranged on the lateral ultra-thin LED backlight achieving device from the top to bottom. The lateral ultra-thin LED backlight achieving device provided by the utility model can effectively balance the temperature of an LED backlight device, and meanwhile, can reduce the cost of backlight for high-performance liquid crystals.
Description
Technical field
The utility model relates to a kind of LED-backlit implement device, is specifically related to a kind of side LED ultrathin backlight implement device.
Background technology
Present stage, the advantages such as liquid crystal display is lightweight owing to having, volume is little, little power consumption, radiation is low, quality is good, be widely used in the individual consumer's goods such as notebook computer, computer monitor, TV.Because LCD panel itself does not have the characteristics of luminescence, therefore must on the LCD panel, add a light emitting source, can reach display effect, backlight source module is to provide the optical module of LCD display back light.
The LCD backlight source module can be used light emitting diode (LED), cold-cathode fluorescence lamp (CCFL), external electrode fluorescent lamp (EFFL) etc. as light source.
On market, the backlight of giant-screen LCD main flow remains CCFL, but, along with the appearance of the development, particularly high-power LED chip of semiconductor technology, the LED luminance and efficiency has had significant raising, make the LED-backlit source more and more be applied to LCD backlight in.Utilizing LED light source is that panel backlight has a lot of advantages as LCD panel backlight than with common CCFL.Wherein the most significantly improving is the expansion of colour gamut.Use LED-backlit to there is broader colour gamut, realize more gorgeous color.But also can realize dynamically controlling the RGB mixed light, and adjust white balance between 9600K and 650OK, and can sacrificing luminance and contrast.
LED-backlit, in the designing and making process, is different from CCFL backlight fully at present, mainly contains two kinds of side-light type and straight-down negatives.The side-light type scheme adopts side emitting, utilizes the blooming piece such as light guide plate that light is turned to, on the LCD panel in guiding dead ahead.What the straight-down negative scheme was neat by LED is arranged in over against the direction of LCD panel, utilizes the blooming pieces such as light guide plate, and by photoconduction, to the LCD panel, but existing LED-backlit installation cost is higher, easily aging, and the local temperature that works long hours is high.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of side LED ultrathin backlight implement device is provided, and this device is the temperature of balanced described LED-backlit device effectively, and cost of manufacture is low simultaneously.
For achieving the above object, the utility model provides a kind of side LED ultrathin backlight implement device, and described side LED ultrathin backlight implement device is provided with successively from top to bottom liquid crystal panel, the first diffuser plate, blast plate, support frame backlight, band camber line reflector, is sidelong LED array and backboard.
Be provided with the second diffuser plate between described support frame backlight and blast plate.
Described placement direction of being sidelong LED in LED array is horizontal direction.
It is described that to be arranged in the part of being sidelong directly over LED array 6 LED with camber line reflector 7 parallel with the upper surface of described LED.The utlity model has following beneficial effect:
Side described in the utility model LED ultrathin backlight implement device is provided with successively from top to bottom liquid crystal panel, the first diffuser plate, blast plate, support frame backlight, band camber line reflector, is sidelong LED array and backboard, thereby LED light is repeatedly reflected, realize LED-backlit, can under lower cost, realize that like this liquid crystal of superior performance is with backlight.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is that liquid crystal panel, 2 is that the first diffuser plate, 3 is that blast plate, 4 is that the second diffuser plate, 5 is that support frame backlight, 6 is backboard for being sidelong LED array, 7 for being with camber line reflector, 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1, side described in the utility model LED ultrathin backlight implement device is provided with successively from top to bottom liquid crystal panel 1, the first diffuser plate 2, blast plate 3, support frame backlight 5, band camber line reflector 7, is sidelong LED array 6 and backboard 8, be provided with the second diffuser plate 4 between described support frame backlight 5 and blast plate 3, described placement direction of being sidelong LED in LED array 6 is horizontal direction, and described to be arranged in the part of being sidelong directly over LED array 6 LED with camber line reflector 7 parallel with the upper surface of described LED.。LED light repeatedly can be reflected by side described in the utility model LED ultrathin backlight implement device, thereby realize LED-backlit, effectively reduce cost backlight for the high-performance liquid crystal simultaneously.
