Abstract
An LED backlight module comprises a light guide plate (1) and an LED light source (2). The light guide plate (1) is spliced by at least two light guide plate units, contact sections (3) of the adjacent light guide plate units are coated with reflective or light-proof materials, one side or the bottom surface of each light guide plate unit is used as an incident plane (4), and each light guide plate unit is provided with an independent LED light source group facing the incident plane. The LED backlight module has subarea backlight and subarea display effects, so that power consumption for display of a mobile phone is lowered, and flexibility of the mobile phone is improved. When subarea display is required, the LED light source group within the subarea is lighted, so that backlight of an LCD (liquid crystal display) of the subarea is uniform by the aid of the light guide plate unit of the subarea. When full-screen display is required, the light guide plate units of all subareas are lighted simultaneously, so that the whole display screen is uniform in backlight by means of closed combination of the light guide plates of all the subareas.
Description
Technical field
The utility model relates to the backlight technical field of mobile phone display screen, relates in particular to a kind of LED-backlit module.
Background technology
Ultra-thin big screen mobile phone is the development trend of mobile phone industry, yet screen size is big more, and its power problems is outstanding more, and bigger screen means bigger display screen drive current and backlight drive electric current.Now the used display screen of mobile phone on the market generally adopts full screen display, and the user only wanting the time of watching, having or not under the situation of information such as missed call, all must light full framely, and this has wasted a large amount of electric energy undoubtedly.Display screen is the bigger parts of mobile phone supply current, and its supply current can be divided into LCD drive current and LED drive current backlight, and LED drive current backlight occupies than great share.The part backlight of mobile phone provides light source by a plurality of LED lamps.If, reduce LED lamp drive current backlight for reducing power consumption, then can cause brightness of display screen not enough, if close local LED lamp backlight, can cause brightness of display screen inhomogeneous.
The utility model content
Be the problem that overcomes the not enough of prior art and exist, the utility model provides a kind of LED-backlit module of realizing that subregion is backlight, subregion shows, to reduce the handset displays power consumption.
The utility model is realized through following technical scheme: a kind of LED-backlit module; Comprise LGP and led light source; Said LGP is spliced by at least two LGP unit, and is coated with reflective on the contacting section of adjacent LGP unit or separated luminescent material; Said each LGP unit all is provided with a side or bottom surface as incidence surface, and is provided with the independent led light source group towards this incidence surface.
Said led light source group comprises several equally distributed led light sources towards incidence surface.
The utility model and prior art relatively adopt the LED-backlit module that subregion is backlight, subregion shows, to reduce the handset displays power consumption, promote the flexibility that the user uses mobile phone.When the needs subregion shows, only light the led light source group of this subregion, the LGP unit through this subregion makes this subregion LCD even back; When needs are displayed in full screen, light the LGP unit of all subregions simultaneously, the combining closely of the LGP through each subregion so that entire display screen is evenly backlight.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the designs simplification figure that uses the display screen of the utility model.
Among the figure: 1-LGP, 2-LED light source, 3-contacting section, 4-incidence surface, the 5-first LGP unit, the 6-second LGP unit.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.Should be pointed out that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.
Shown in accompanying drawing 1, a kind of LED-backlit module comprises LGP 1 and led light source 2, and said LGP 1 is spliced structure, comprises at least two LGP unit, is provided with reflector layer or separated photosphere between the contacting section 3 of said adjacent LGP unit.In the utility model; Said reflector layer or be to be sprayed at reflective on the contacting section 3 or at a distance from optical coating, printing ink etc. at a distance from photosphere; The contacting section 3 of perhaps adjacent LGP unit utilizes prior art to take other at a distance from light, reflective processing mode, should fall into the protection domain of the utility model.Said each LGP unit all is provided with a side or bottom surface as incidence surface 4, and is provided with the independent led light source group towards this incidence surface 4.Said led light source group can perhaps make up separately through system program control and light.
Said led light source group comprises several equally distributed led light sources 2 towards incidence surface 4.
Accompanying drawing 2 is the designs simplification figure that use a kind of display screen of the utility model.This display screen comprises the LED-backlit module, is covered in the LCD (LCD is the abbreviation of Liquid Crystal Display) of LED-backlit module upper bottom surface and is connected in the reflector of LED-backlit module bottom surface.Said LGP 1 is spliced by the first LGP unit 5 and the second LGP unit 6, forms upper and lower two subregions.The said first LGP unit 5 and the second LGP unit 6 are incidence surface 4 with a left side or right flank, and the led light source group towards this incidence surface 4 is set.Said incidence surface 4 is perpendicular to the contacting section 3 of two LGP unit.In the present embodiment, said led light source group comprises three evenly distributed led light sources 2.When the needs subregion shows, only light the led light source group backlight of particular zones, the LGP unit through this subregion makes this subregion led light source even back; Shown in accompanying drawing 2, when the first LGP unit, 5 corresponding led light source groups are lighted, these first LGP unit, 5 leaded lights, the second LGP unit 6 is leaded light not.When needs are displayed in full screen, light the led light source group simultaneously, the first LGP unit 5 and the second LGP unit 6 be leaded light simultaneously, the combining closely so that whole screen is the evenly backlight of LGP through each subregion.
The content of mentioning in the foregoing description is not to be the qualification to the utility model, and under the prerequisite of the inventive concept that does not break away from the utility model, any conspicuous replacement is all within the protection domain of the utility model.
Claims (2)
1. a LED-backlit module comprises LGP (1) and led light source (2), and it is characterized in that: said LGP (1) is spliced by at least two LGP unit, and is coated with reflective on the contacting section (3) of adjacent LGP unit or separated luminescent material; Said each LGP unit all is provided with a side or bottom surface as incidence surface (4), and is provided with the independent led light source group towards this incidence surface.
