Abstract

The utility model relates to a light guide plate, and particularly relates to a light guide plate structure adopting an LED (light emitting diode) light emitting source. The light guide plate provided by the utility model is characterized in that one surface of a light-passing plate is printed with light guide points; one side edge of the light-passing plate, which is close to an interruption type LED line type light source, is provided with a blank area, a plurality of light guide points which are arranged into triangles with vertexes up are printed on the blank area; and the position of each triangular corresponds to the position between adjacent two LEDs of the interruption type LED line type light source. The light guide plate provided by the utility model is applied to the interruption type LED line style light source to obtain a backlight source which can emit light uniformly.

Description

LGP
Technical field
The utility model relates to LGP, relates in particular to the light conducting plate structure that adopts the LED light emitting source.
Background technology
LGP is generally to be applied in liquid crystal display, as an important component part in LED-backlit source.LGP is the illumination of the line sources such as CCFL (CCFL), fluorescent tube to be changed into a kind of structure member of illuminated by surface light source.
LGP is the acryl of utilizing optical grade/PC sheet material, and the bottom surface that then is used in the acryl sheet material of optical grade or PC sheet material stamps light guiding points (or claim " site ") with printing technologies such as UV half tone or laser.LGP is that the light that utilizes optical grade acryl/PC sheet material to draw to send from line source is in the stop on optical grade acryl sheet material surface, when light is mapped to each light guiding points, reverberation can toward all angles diffusion, then destroy conditioned reflex and penetrate by LGP is positive.By various densitys, light guiding points not of uniform size, can make the LGP uniformly light-emitting on the exiting surface of LGP.
Existing LGP is to be applied in the line sources such as CCFL (CCFL), fluorescent tube.Along with the consideration of energy-saving and environmental protection, begin to have and adopt LED as the light emitting source of LCD backlight.Yet LED is a kind of spot light, in order to have the characteristic effect of line source, it is generally even distribution plurality of LEDs on a long strip type substrate, be that it is discontinuous LED linear light sources, therefore this discontinuous LED linear light sources is to have LED position and bright alternately dark without the LED position, if the LGP of existing CCFL to this discontinuous LED linear light sources, obviously can be affected whole display picture taste like this.
The utility model content
Therefore, the utility model proposes a kind of improved LGP, can be applied in discontinuous LED linear light sources, and avoid bright dark Alternate Phenomenon backlight, and make bright dipping backlight even.
The utility model adopts following technical scheme:
LGP is that the one side at a light-passing board is printed with light guiding points.Wherein, this light-passing board leaves one section clear area being positioned at a side that closes on discontinuous LED linear light sources, and be printed with on this clear area and a plurality ofly be arranged in triangular shaped a plurality of light guiding points of just putting, and each leg-of-mutton position is corresponding to the position between adjacent 2 LED of this discontinuous LED linear light sources.
The utility model adopts as above technical scheme, discontinuous LED linear light sources is formed backlight uniformly.Position by the dark space of correspondence between adjacent 2 LED of discontinuous LED linear light sources is printed with triangular shaped light guiding points, can be with the luminance raising without the LED dark space, and make LED over against the zone with basic identical over against regional luminance without LED.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Figure 1ly, the LGP of embodiment is that the one side at a light-passing board 1 is printed with light guiding points.Wherein, this light-passing board 1 leaves one section clear area 11 being positioned at a side that closes on discontinuous LED linear light sources 2, and be printed with on this clear area 11 and a plurality ofly be arranged in a plurality of light guiding points of triangular shaped 101 of just putting, and each position of triangular shaped 101 is corresponding to the position 22 between adjacent 2 light emitting diodes (LED) 21 of this discontinuous LED linear light sources 2.
The LGP of the present embodiment is printed with triangular shaped light guiding points by the position of the dark space of correspondence between adjacent 2 LED of discontinuous LED linear light sources, can be with the luminance raising without the LED dark space, and make LED over against zone and basic identical over against regional luminance without LED, bright, the shadow that have solved the LED lamp of discontinuous LED linear light sources are joined problem, thereby have realized that the backlight bright dipping is even.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.

Claims (1)

1. LGP, that one side at a light-passing board is printed with light guiding points, it is characterized in that: this light-passing board leaves one section clear area being positioned at a side that closes on discontinuous LED linear light sources, and be printed with on this clear area and a plurality ofly be arranged in triangular shaped a plurality of light guiding points of just putting, and each leg-of-mutton position is corresponding to the position between adjacent 2 LED of this discontinuous LED linear light sources.
