Abstract
The utility model discloses a backlight source with good display effect, which comprises a light guide plate and a plurality of lamp beads, wherein the plurality of lamp beads are uniformly distributed on the side surface of the top of the light guide plate and are connected with conductive wires, the outer ring of the upper surface of the light guide plate is provided with a convex edge, the height of the convex edge is 0.2mm, the upper surface of the light guide plate is pasted with a diffusion film, the lower surface of the light guide plate is pasted with a reflective film, the left side, the right side and the bottom side are respectively provided with an edge covering film, and the convex edge of the light guide plate is provided with an external liquid crystal module by upward pressing; through increasing protruding edge assembly pressfitting outside the circle can not contact with the light guide plate middle part, the difficult outdiffusion of dust, the display effect is good, and the yields is high, uses visual effect to be good, effectively satisfies the operation requirement.
Description
Technical Field
The utility model belongs to the photoelectricity field, in particular to better backlight of display effect.
Background
The light guide plate of backlight is after the pad pasting is accomplished, need accomplish the pressfitting to the light guide plate to the LCD module again on, with regard to the light guide plate of using at present, its one side with the liquid crystal complex is complete smooth, certain operation requirement can be satisfied to the complete smooth structure of this kind of light guide plate contact surface, but also there is great defect, the mid portion of light guide plate probably has the dust, the dust can the outdiffusion behind the liquid crystal pressfitting to the light guide plate, the backlight display effect is unsatisfactory, the yields is low, use visual effect is not good, can't effectively satisfy the operation requirement.
The to-be-solved technical problem of the utility model is to provide a dust can not the outdiffusion during assembly pressfitting, the display effect is good, the yields is high, use visual effect is good, effectively satisfy operation requirement's backlight.
SUMMERY OF THE UTILITY MODEL
Dust can outdiffusion when solving above-mentioned prior art assembly pressfitting, backlight display effect is unsatisfactory, the yields is low, use visual effect not good, can't effectively satisfy operation requirement scheduling problem, the utility model discloses a following technical scheme:
the utility model provides a backlight that display effect is good, including light guide plate and a plurality of lamp pearl, a plurality of lamp pearl evenly distributed sets up on light guide plate top side and is connected with the conductor wire, light guide plate upper surface outer lane department is equipped with protruding edge, protruding edge height is 0.2mm, light guide plate upper surface is posted diffusion barrier, lower surface and is posted the reflective membrane, controls and the bottom side all is equipped with the envelope membrane, the protruding edge top pressure of light guide plate is equipped with external liquid crystal module.
The beneficial effects of the utility model reside in that: through increasing protruding edge assembly pressfitting outside the circle can not contact with the light guide plate middle part, the difficult outdiffusion of dust, the display effect is good, and the yields is high, uses visual effect to be good, effectively satisfies the operation requirement.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a backlight source with good display effect includes a light guide plate 1 and a plurality of lamp beads 2, the plurality of lamp beads 2 are uniformly distributed on the side surface of the top of the light guide plate 1 and connected with conductive wires 21, a convex edge 11 is arranged at the outer ring of the upper surface of the light guide plate 1, the height of the convex edge 11 is 0.2mm, a diffusion film is pasted on the upper surface of the light guide plate 1, a reflective film is pasted on the lower surface of the light guide plate, side surfaces of the left side and the right side and the bottom side are respectively provided with a surrounding film 12, an external liquid crystal module is arranged on the convex edge of the light guide plate 1 in an upward pressing manner, when the assembly and the pressing are performed, the liquid crystal module only presses the convex edge of the light guide plate to be in direct contact with the convex edge, and is not in contact with the middle of the light guide plate, so that dust is not diffused outwards even in the middle of the light guide plate, the display effect is not affected, and the yield is higher.
The beneficial effects of the utility model reside in that: through increasing protruding edge assembly pressfitting outside the circle can not contact with the light guide plate middle part, the difficult outdiffusion of dust, the display effect is good, and the yields is high, uses visual effect to be good, effectively satisfies the operation requirement.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
