Abstract
The utility model relates to the field of a backlight source, in particular to a liquid-crystal display backlight source for a handset. The liquid-crystal display backlight source comprises a backlight source substrate which is provided with a light guide plate; one surface silk-screen thin layer of the light guide plate is a lighting material layer; holes or slots are carved at the circumference of the backlight source substrate; light-emitting diodes (LED) or LED pasters are embedded in the holes or the slots; and the luminescent surface of the LED is vertical to the end surface of the light guide plate. When the LED is electrified and shines, light beam leads the whole surface of the light guide plate to shine by utilizing the complex optical principle of the light guide plate and the lighting material thin layer, therefore, an LED spot light source is changed into a soft surface light source with two luminescent surfaces; and a light-reflecting membrane is bonded on the back surface of the LED so as to reinforce the luminous intensity of the surfaces of the guide light plate needing to shine.
Description
[technical field]
The utility model relates to the backlight field, specifically refers to a kind of mobile phone LCD backlight source that adopts led light source.
[background technology]
LCD (LCD) is widely used in computer, communication apparatus, television set and other various displays.Now general LCD backlight source is used cold-cathode tube more, advantage brightness height, and shortcoming is the high voltage source that needs high pressure.And the mobile phone LCD backlight source, many applied films cold light source EL EL sheet, it is very thin that advantage can be done, and shortcoming is that the life-span is short, and brightness easily decays, and also need go up a few kilocycle high frequency electric sources of hectovolt, easily wave interference.
[utility model content]
The brightness that the utility model purpose is to solve above-mentioned mobile phone display screen is the problem of decay easily, and a kind of mobile phone LCD backlight source of reasonable in design, dependable performance is provided.
A kind of mobile phone LCD backlight source, comprise the backlight substrate, described backlight substrate is provided with LGP, a surperficial silk-screen thin layer of LGP is the lighting material layer, the backlight substrate periphery is carved and is provided with hole or groove, stud with LED or LED paster in described hole or the groove, the vertical LGP end face of the light-emitting area of LED.
Preferably, described diode (LED) or LED paster stick with glue agent and LGP encapsulation, and described diode (LED) or LED paster post reflective membrane outward.
The utility model mobile phone LCD backlight source, comprise the backlight substrate, described backlight substrate is provided with LGP, a surperficial silk-screen thin layer of LGP is the lighting material layer, the backlight substrate periphery is carved and is provided with hole or groove, stud with LED or LED paster in described hole or the groove, the vertical LGP end face of the light-emitting area of LED.Behind the LED electrified light emitting, light is through the complicated optical principle of LGP and lighting material thin layer, the whole surface light emitting of LGP has then become the area source of soft double-side to the LED spot light, and LED sticks at the back side luminous intensity that reflective membrane or brightness enhancement film increase need light-emitting area.
[description of drawings]
Fig. 1 is the structural representation of the utility model one embodiment.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model mobile phone LCD backlight source, comprise the backlight substrate, described backlight substrate is provided with LGP 1, a surperficial silk-screen thin layer of LGP 1 is the lighting material layer, the backlight substrate periphery is carved and is provided with hole or groove 2, stud with LED or LED paster 3 in described hole or the groove, the vertical LGP end face of the light-emitting area of LED 3.
Preferably, described diode (LED) or LED paster 3 stick with glue agent and LGP 1 encapsulation, described diode (LED) or the LED paster 3 outer reflective membranes that post.
The area size of LGP 1 is cut out according to the size requirements of LCDs, and LGP 1 periphery becomes the equidistant holes or the groove 2 of rule with milling machine or laser engraving.Also available Shooting Technique forms hole or groove 2, the degree of depth in hole and diameter, the degree of depth of groove and width can be inlayed and advance LED or LED paster 3 or the integrated chip that welds with printed circuit board (PCB), LED luminous tube or paster or chip 3 in advance on printed circuit board (PCB) the grouping series and parallel weld.
According to the DC voltage of selecting for use, the form of LED grouping series and parallel connects.It is good to stick with glue the agent packaging protection then, pastes reflective membrane again.
Show for large-screen lc, adopt the LED luminous tube; And in, the small screen liquid crystal display, adopt the LED paster; To mobile phone display screen,, adopt the integrated chip welding because of thickness below the 1.3mm.
LED adopts LED luminous tube or the paster or the chip of single spectrum, two spectrum, three primary colours according to actual needs, or pure white light.
The thickness of LGP depends on the LCDs of the LED size of employing and practical application and decides.
The utility model is applied to large-screen lc and shows, the laptop computer liquid crystal display, and the mobile phone liquid crystal display, backlight fields such as other liquid crystal displays also can be applicable to the dull and stereotyped attached lighting field that helps.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
