Abstract
The utility model provides a backlight laser dot light guide plate. The backlight laser dot light guide plate comprises a laser dot surface composed of pits arrayed scatteredly. At least two groups of laser dot belts of zonal distribution are arranged at the lower end of the laser dot surface. The laser dot belts consist of arrayed pits. The backlight laser dot light guide plate has the advantages that by arranging the laser dot belts , light-emitting diode (LED) backlight is dispersed first through the laser dot belts, and the uniformity of the backlight is improved preferably.
Description
Technical field
The utility model relates to a kind of backlight laser dot light guide plate.
Background technology
Light guide plate is to utilize the method for ejection formation that propylene is pressed into ganoid plate, then at the acryl flat board with high reflectance and the material of extinction not, stamp circular or square light guiding points in the plate bottom surface with screen painting, come diffusing light with this.When light was mapped to light guiding points, light can toward all directions reflection, then destroy conditioned reflex and penetrate by light guide plate is positive.For making uniformly light-emitting, must utilize light guiding points to guarantee that light is roughly the same toward the probability of all directions reflection.
Existing backlight laser dot light guide plate comprises the laser dot surface, and the laser dot surface is by being made of the concave point that disperses array, and its deficiency is backlight still even not after being to disperse.
The utility model content
The utility model provides a kind of backlight laser dot light guide plate for overcoming above-mentioned deficiency.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of backlight laser dot light guide plate, comprise the laser dot surface that is consisted of by the concave point that disperses array, the lower end of described laser dot surface also is provided with the laser site band that at least two groups are zonal arrangement, and described laser site band is comprised of the concave point of array.
Preferably, described laser site band is the waveform with certain flexibility.
Preferably, described laser site band is provided with the 4-6 group.
The beneficial effects of the utility model are: by the setting of laser site band, so that LED-backlit is at first disperseed by laser site band, can increase better homogeneity backlight.
Description of drawings
Fig. 1, the one-piece construction figure of embodiment backlight laser dot light guide plate.
Fig. 2, the A-A partial enlarged drawing of Fig. 1.
Fig. 3, the B-B partial enlarged drawing of Fig. 2.
Embodiment
A kind of backlight laser dot light guide plate, its one-piece construction figure is referring to accompanying drawing 1, comprise light guide plate 1, LED-backlit source 2 and the laser dot surface 3 that is consisted of by the concave point that disperses array, the lower end of laser dot surface 3 also is provided with 5 groups of laser site bands 4 that are zonal arrangement, Fig. 2 is the A-A partial enlarged drawing of Fig. 1, and Fig. 3 is the B-B partial enlarged drawing of Fig. 2.Referring to Fig. 3, laser site band 4 is comprised of three row concave points, and the laser site band 4 that three row concave points form is the waveform with certain flexibility.The present embodiment so that LED-backlit is at first disperseed by laser site band 4, can increase homogeneity backlight by the setting of laser site band 4 better.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
