Abstract
The utility model relates to a technical field of a computer peripheral, in particular to a backlight unit of an ultrathin liquid crystal screen. The backlight unit of the ultrathin liquid crystal screen comprises a light guide plate and light-emitting diode (LED) units which are placed at two sides of the light guide plate. The LED unit comprises a LED light. An in-light surface is placed at a side which the light guide plate is opposite to the LED light, the out-light surface is placed at the top surface of the light guide plate, the in-light surface is a slope, the LED light is installed aslant, and the in-light surface is opposite to the LED light. By adoption of the in-light surface of the guide light plate set a slope, the backlight units enables the light from the LED light to enter the guide light plate through the slope, resolves the problem of light leakage efficiently, and saves optical energy.
Description
Technical field
The utility model relates to the computer peripheral technical field, specifically, relates to a kind of backlight module of Ultrathin liquid crystal display screen.
Background technology
Along with the development of science and technology, the technology of LCDs is more and more higher, computer screen from before CRT change present LCDs into, itself is not luminous for LCDs, but passive luminous; So need backlight module that light source is provided, LCDs can be divided into CCFL backlight module and LED-backlit module from the classification of light source, because LED has characteristics energy-conservation, long service life, the LCDs of most has all adopted the LED-backlit module, and in the LED-backlit module, be divided into straight-down negative and side-light type according to the position of LED; Because side-light type can reduce the thickness of display screen, and can save certain LED, therefore mostly adopt the LED-backlit module of side-light type, and the thickness of the LGP in the present Ultrathin liquid crystal display screen can be accomplished 0.1mm, and the thickness minimum of LED only can reach 0.4mm, and the LED operated by rotary motion is in the side of LGP, and the LED in therefore a lot of backlight modules is luminous only, and some enters LGP, cause the light leak problem, and the problem of luminous energy waste.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of backlight module of Ultrathin liquid crystal display screen is provided, and the light that this backlight module can effectively utilize the LED module to send is conducive to energy-conservation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of backlight module of Ultrathin liquid crystal display screen, comprise LGP and the LED module that is arranged on the LGP both sides, described LED module comprises the LED lamp, the described LGP side relative with the LED lamp is for advancing the light face, the upper surface of LGP is exiting surface, described to advance the light face be the inclined-plane, and described LED lamp is obliquely installed, and advance the light face and the LED lamp arranges in opposite directions.
The utility model will advance the light face and be arranged to the inclined-plane, and the LED lamp is obliquely installed, and the cross-sectional area of the relative LED lamp of LGP increases, thereby so that the light that the LED lamp sends enters LGP increases.
Further, the below of described LGP is provided with reflecting piece, fits in the lower surface of reflecting piece and LGP.
By reflecting piece is set below LGP, penetrate from light-emitting area so that enter the light of LGP, improve the luminous utilization rate of LED lamp.
Further, the exiting surface of LGP is provided with scattering sheet.
Scattering sheet is set, and the light of being convenient to shoot out from LGP shines on the display screen.
Further, the top of described scattering sheet is provided with the anti-reflection film of fitting with it.
Anti-reflection film is set, can assists visible light to pass through.
Further, the angle between the lower surface of advancing light face and LGP of described LGP is 15 ~ 75 degree.
In order to increase the inlet of LED light, also to consider the installation of LED lamp simultaneously, the angle between the lower surface of advancing light face and LGP of LGP is set to 15 ~ 75 degree and is advisable.
Further, the angle between the lower surface of advancing light face and LGP of described LGP is 45 degree.
The beneficial effect that the utility model is obtained is: the utility model is set to the inclined-plane by the light face that advances of LGP, so that the light that LED sends enters LGP by the inclined-plane, can effectively solve the light leak problem, saves luminous energy.
Description of drawings
Fig. 1 is part-structure cross-sectional schematic of the present utility model.
Reference numeral is:
1---LGP 2---reflecting piece
3---LED lamp 4---scattering sheet
5---anti-reflection film 6---LED module.
The specific embodiment
Below in conjunction with accompanying drawing 1, and the specific embodiment is described further the utility model.
Embodiment: referring to Fig. 1.
A kind of backlight module of Ultrathin liquid crystal display screen, comprise LGP 1 and the LED module 6 that is arranged on LGP 1 both sides, described LED module 6 comprises LED lamp 3, the relative side of described LGP 1 and LED lamp 3 is for advancing the light face, the upper surface of LGP 1 is exiting surface, advance the light face tilt and be arranged to the inclined-plane, LED lamp 3 is obliquely installed, and advances light face and LED lamp 3 in opposite directions.The thickness of LED lamp 3 equates with the width that advances the light face at this moment, or approximately equal.The light that LED sends nearly all can enter LGP 1 by advancing the light face, thereby the situation that the light that minimizing LED lamp 3 sends spills is saved luminous energy simultaneously.
Because the exiting surface of LGP 1 is arranged on the one side relative with display screen, so the lower surface of LGP 1 need to reflect light, and transmissive not; Therefore be provided with reflecting piece 2 below described LGP 1, reflecting piece 2 is fitted with the lower surface of LGP 1.After reflecting piece 2 is set, penetrate from light-emitting area so that enter the light of LGP 1, improve the luminous utilization rate of LED lamp 3.
For further, increase the light effect that of LGP 1, on the exiting surface of LGP 1, be provided with successively scattering sheet 4 and anti-reflection film 5.After scattering sheet 4 and anti-reflection film 5 were set, the light of being convenient to shoot out from LGP 1 shone on the display screen.
When implementation arranges the inclined-plane, need to consider the installation of LED lamp 3, and LED light inlet, therefore the angle between the lower surface of advancing light face and LGP 1 of described LGP 1 is set to 15 ~ 75 degree.Best angle is 45 degree.
The utility model has been done to explain, and those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from essence and the scope of technical solutions of the utility model.
