Abstract
The utility model discloses a noctilucent lighting LED (Light Emitting Diode) backlight liquid crystal display (LCD). The noctilucent lighting LED backlight LCD comprises an LCD screen and a light guide device behind the LCD screen, wherein an LED array module is arranged behind the light guide device, and the LCD screen, the light guide device and the LED array module are all mounted in a frame body of the LCD. Noctilucent plates are arranged at the outer side of the edge of the light guide device, noctilucent powder is coated on the noctilucent plates, and one face of each noctilucent plate with the noctilucent powder faces the light guide device and is provided with a certain inclination angle towards the outside of the LCD screen; the noctilucent plates are arranged behind the frame body, and the part of the frame body in front of the noctilucent plates is transparent frame sides; and noctilucent plates are also arranged on the opaque part in front of the frame body, and noctilucent powder is coated on the noctilucent plates. When people get up to fetch objects or walk in rooms at midnight, an electric lamp is not needed to be additionally turned on, thus great convenience is provided for the nocturnal behavior of people; and the lighting basically does not need separate energy consumption, so that the noctilucent lighting LED backlight LCD is more environment-friendly and energy-saving.
Description
Technical field
The utility model relates to a kind of LCD, especially a kind of LED-backlit LCD that can send fluorescence at night.
Background technology
The LED-backlit LCD is applied on high-end LCD, LCD TV now.The LCD of this LED-backlit need be used great power LED; Structure is the direct-light type LED backlight structure as the one of which; Its structure description is: the guiding device with multilayer optical character plate is set at liquid crystal display at the back; At guiding device the led array module is set at the back, then they is all wrapped in the framework.
The LED-backlit display of said structure, the edge meeting light leak of guiding device, this makes the part energy of LED lamp waste.
The utility model content
The purpose of the utility model is to provide a kind of LED-backlit LCD of luminescent lighting, and the light that can display be missed and the light that sends collect, and throw light on as the low light level.
The utility model is realized through following technical scheme:
The LED-backlit LCD of luminescent lighting comprises: the guiding device of liquid crystal display and liquid crystal display back, be provided with the led array module at the back at guiding device, and liquid crystal display, guiding device and led array module are installed in the framework of display; The outside, edge at said guiding device is provided with luminous plate, on luminous plate, is coated with luminescent powder, and luminous plate has the one side of luminescent powder towards said guiding device, and certain inclination angle is arranged outside liquid crystal display; Luminous plate is located at the back of said framework, and a part of framework of that of luminous plate front is transparent edge; Be provided with luminous plate equally on the opaque part in said framework front, be coated with luminescent powder on this luminous plate.
Preferably: said led array module is provided with reflecting plate at the back.
Enemy choosing ground: said guiding device comprises by the led array module successively to the range upon range of diffuser plate of liquid crystal display direction, first diffusion barrier, light-collecting piece, second diffusion barrier, brightening piece.
Preferably: said inclination angle is 45 °.
Preferably: said luminescent powder is that the luminescent powder of the light-accumulating luminous material of rear-earth-doped aluminate perhaps is zinc sulphide series luminescent powder.
The beneficial effect of the utility model is following: compare prior art, the utility model can store the luminous energy that the light that spills the slit between the light that spills from the guiding device edge, led array module and the guiding device and liquid crystal display send.After on that night turned off the light in the room, luminescent powder sent faint light above the display, and this light can provide the illumination as moon luminance brightness, and can continue more than 8 hours.Like this, the article of taking if people stand up midnight, or walk about in the room, do not need to have opened electric light in addition, provide great convenience for people's behavior at night, and this illumination just need not to expend separately the energy, more environmental protection and energy saving at all.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Fig. 2 is the structural drawing of guiding device.
Among the figure: reflecting plate 1, led array module 2, guiding device 3, liquid crystal display 4, framework 5, luminous plate 6;
