It is different, generally comprise backlight module, liquid crystal display panel, backboard and frame.Backlight module and liquid crystal display panel are fixed on backboard
In the cavity formed with frame.
In the prior art, when realizing curved design, typically use and liquid crystal display panel bent into certain radian,
And coordinate the method for curved surface backlight module.However, in the backlight module of curved surface, the LED backlight of generally use straight-down negative structure,
Since the light-emitting surface of light guide plate is curved surface, the intensity of the middle part light of light-emitting surface can be caused high, and the intensity of four period-luminosity of light-emitting surface
It is low, so as to cause light extraction uneven, influence the display effect of display.
Utility model content
The purpose of this utility model is to provide a kind of brand-new backlight module curved surface ultra-thin LCD, it has hair
The uniform backlight module of light, so as to solve above-mentioned technical problem.
In the utility model embodiment, there is provided a kind of brand-new backlight module curved surface ultra-thin LCD, it includes
Backlight module and curved surface liquid crystal display panel, the backlight module include reflective back plane, array arrangement in the reflective back plane
Multiple LED point light sources and light guide plate, the light guide plate includes incidence surface and the light-emitting surface opposite with the incidence surface, described
Incidence surface is plane, and the light-emitting surface is the corresponding curved surface of shape with the curved surface liquid crystal display panel, the multiple LED
Point light source is set relative to the incidence surface of the light guide plate, from the center of the reflective back plane to the surrounding of the reflective back plane,
Spacing between the LED point light source is gradually reduced.
In the utility model embodiment, be additionally provided with ripples shape lines on the light-emitting surface, and the ripples shape lines from
The center of the light-emitting surface is gradually intensive to the edge of the light-emitting surface.
In the utility model embodiment, the backlight module, which further includes, is arranged at the light guide plate and the LCD display
Polaroid between plate.
In the utility model embodiment, the brand-new backlight module curved surface ultra-thin LCD, which further includes, is arranged at institute
State the blast piece between light guide plate and the polaroid.
Compared with prior art, the brand-new backlight module curved surface ultra-thin LCD of the utility model, using brand-new
LED light source arrangement backlight module, from the center of the reflective back plane to the surrounding of the reflective back plane, the LED points
Spacing between light source is gradually reduced, so that the light extraction of the light-emitting surface of light guide plate is more uniform；In addition, it is described go out
Ripples shape lines is additionally provided with smooth surface, and the ripples shape lines is from the center of the light-emitting surface to the edge of the light-emitting surface
It is gradually intensive, the light-emitting uniformity of the light-emitting surface of the light guide plate is further increased, it is bent to improve the brand-new backlight module
The display effect of face ultra-thin LCD.
Brief description of the drawings
Fig. 1 is the structural representation for the brand-new backlight module curved surface ultra-thin LCD that the utility model embodiment provides
Figure.
Fig. 2 is the schematic diagram of the lines of the light-emitting surface of the light guide plate shown in Fig. 1.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
It is described in detail below in conjunction with realization of the specific embodiment to the utility model.
Referring to Fig. 1, the utility model embodiment provides a kind of brand-new backlight module curved surface ultra-thin LCD, its
Including the backlight module being arranged in order（Do not identify）, blast piece 40, polaroid 50 and liquid crystal display panel 60.The liquid crystal display
Panel 60 is curved surface, and correspondingly, the blast piece 40 and the polaroid 50 are also curved surface.
The backlight module includes reflective back plane 10, array arrangement in multiple LED point light sources in the reflective back plane 10
20 and light guide plate 30.The light guide plate 30 includes incidence surface 31 and the light-emitting surface 32 opposite with the incidence surface 31, it is described enter
Smooth surface 31 is plane, and the light-emitting surface 32 is the corresponding curved surface of shape with the liquid crystal display panel 60.The multiple LED
Point light source 20 is set relative to the incidence surface 31 of the light guide plate 30, from the center of the reflective back plane 10 to the reflective back plane
10 surrounding, the spacing between the LED point light source 20 is gradually reduced, so that entering light into the light guide plate 30
It is weaker and surrounding is stronger among the light in face 31, so that the light extraction of the light-emitting surface 32 of the light guide plate 30 is more uniform.
Further, as shown in Fig. 2, being additionally provided with ripples shape lines on the light-emitting surface 32 of the light guide plate 30, and it is described
Ripples shape lines is gradually intensive to the edge of the light-emitting surface 32 from the center of the light-emitting surface 32, can further improve described
32 surrounding of light-emitting surface goes out luminous intensity, so as to improve the light-emitting uniformity of the light-emitting surface 32 of the light guide plate 30.
In conclusion the brand-new backlight module curved surface ultra-thin LCD of the utility model, using brand-new LED light source
Arrangement backlight module, from the center of the reflective back plane to the surrounding of the reflective back plane, between the LED point light source
Spacing is gradually reduced, so that the light extraction of the light-emitting surface of light guide plate is more uniform；In addition, also set on the light-emitting surface
Ripples shape lines is equipped with, and the ripples shape lines is gradually intensive to the edge of the light-emitting surface from the center of the light-emitting surface,
The light-emitting uniformity of the light-emitting surface of the light guide plate is further increased, improves the ultra-thin liquid crystal of the brand-new backlight module curved surface
The display effect of display.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
