Abstract
The utility model provides an LED backlight monitor of fluorescent lighting, which is used for utilizing the light which is leaked from the edge of a light guide device and an LED array module as the weak light illumination so as to save the energy, and comprises a liquid crystal screen and a light guide device which is arranged behind the liquid crystal screen, wherein an LED array module is arranged behind the light guide device, and the liquid crystal screen, the light guide device and the LED array module are installed inside a frame of the monitor; the outer side of the edge of the light guide device is provided with a noctilucent board, noctilucent powder is coated on the noctilucent board, the side of the noctilucent board having the noctilucent powder faces towards the light guide device and forms an oblique angle towards the liquid crystal screen; and the noctilucent board is arranged behind the frame, and the frame in front of the noctilucent board is of a transparent rim. The LED backlight monitor can store the optical energy which is leaked from the edge of the light guide device.
Description
Technical field
The utility model relates to a kind of LCD of LED-backlit, particularly relates to a kind of LCD of direct-light type LED backlight.
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, its general structure is the direct-light type LED backlight structure, its structure description is: the guiding device with multilayer optical character plate is set in the liquid crystal display back, in the guiding device back led array module is set, 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
Technical problem to be solved in the utility model is: provide a kind of LED-backlit display of fluorescent illumination, in order to using from the light that the edge of guiding device and led array module is missed, as low light level illumination, with energy savings.
In order to solve the problems of the technologies described above, the utility model proposes a kind of LED-backlit display of fluorescent illumination, the guiding device that comprises liquid crystal display and liquid crystal display back, be provided with the led array module in photoconduction electro-optical device back, liquid crystal display, guiding device and led array module are installed in the framework of display; The outside, edge at described guiding device is provided with luminous plate, is coated with luminescent powder on luminous plate, and luminous plate has the one side of luminescent powder towards described guiding device, and certain inclination angle is arranged outside liquid crystal display; Luminous plate is located at the back of described framework, and a part of framework of that of luminous plate front is transparent edge.
Preferably: described led array module back is provided with reflecting plate.
Preferably: described guiding device comprises by the led array module successively to the stacked diffuser plate of liquid crystal display direction, first diffusion barrier, light-collecting piece, second diffusion barrier, brightening piece.
Preferably: described inclination angle is 45 °.
Preferably: described luminescent powder be rear-earth-doped aluminate light-accumulating luminous material luminescent powder or be zinc sulphide series luminescent powder.
The beneficial effects of the utility model are as follows:
Compared to existing technology, the utility model can be with the light that spills from the guiding device edge, and the luminous energy that spills in the slit between led array module and the guiding device stores.When display was opened, the light part that LED sends spilt the back and is absorbed by luminescent powder and store from the edge of guiding device.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.
