Abstract
The utility model relates to the technical field of handsets and display screens, and particularly relates to a novel light guide plate, which comprises a plate body. The plate body is covered with screen dots and each screen dot is in the form of a triangular boss. Each triangular l boss is composed of a front sharp corner and a rear sharp corner, wherein the front sharp corner is larger than the rear sharp corner in angle. According to the technical scheme of the utility model, the novel light guide plate improves both the utilization rate and the brightness of the light.
Description
Technical field:
The present invention relates to mobile phone, display screen technology field, refer in particular to a kind of light guide plate.
Background technology:
Light guide plate is to utilize acryl/PC sheet material of optical grade, then, with having high reflectivity and the hitech materials of extinction not, in the acryl sheet material bottom surface of optical grade, with UV screen printing technology, stamps light guiding points.The light that utilizes optical grade acryl sheet material to draw to send from lamp is in the stop on optical grade acryl sheet material surface, and when light is mapped to each light guiding points, reflected light can be toward all angles diffusion, then destroys conditioned reflex and penetrates by light guide plate is positive.By various density, light guiding points not of uniform size, can make light guide plate uniformly light-emitting.The purposes of reflector plate is that the light that bottom surface is exposed is reflected back in light guide plate, is used for improving the service efficiency of light.
Light guide plate design concept comes from the LCDs of notebook computer, is the high-tech product that line source is changed into area source.Optical grade acryl (PMMA)/PC is base material, use the back light model setting technology of LCD display and notebook computer, see through the high light line conductivity of light guiding points, through computer, light guiding points is calculated, make light guide plate light refraction become the equal light state of area source to manufacture moulding.Product adopts spectrophotometry to combine with digital UV printing technology and is made under constant temperature, constant humidity, dustless environmental baseline, have that ultra-thin, superbright, leaded light are even, energy-saving and environmental protection, no dark space, durable, be difficult for the distinguishing features such as yellow, installation and maintenance simple and fast.
Also there is certain problem in existing light guide plate, net-pont design is science not in design, has following several sites production method: 1. silk-screen, 2. die corrosion, 3. laser dotting, 4. machinery hits a little, dot shape: circle, weak point: brightness is low, light guide effect is inhomogeneous.
Summary of the invention:
The object of the invention is for the deficiencies in the prior art, and a kind of light guide plate is provided, improved the utilization factor of light, promote brightness.
For achieving the above object, the present invention adopts following technical scheme, is covered with site on plate body, and site is triangle boss, has front acute angle, rear acute angle on triangle boss, and the angle of front acute angle is greater than the angle of rear acute angle, and one end of plate body is provided with illuminating source.
The density of site is for increasing gradually by the illuminating source density that stretches out.
Beneficial effect of the present invention is: on plate body, be covered with site, site is triangle boss, has front acute angle, rear acute angle on triangle boss, and the angle of front acute angle is greater than the angle of rear acute angle, has improved the utilization factor of light, promotes brightness.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cut-open view of the present utility model.
Fig. 3 is the enlarged drawing at A place in Fig. 2.
Fig. 4 is single lattice point structure schematic diagram of the present utility model.
Embodiment:
See shown in Fig. 1 to Fig. 4: it comprises on plate body 1 and be covered with site 2, site 2 is triangle boss, has front acute angle 3, rear acute angle 4 on triangle boss, and the angle of front acute angle 3 is greater than the angle of rear acute angle 4, and one end of plate body 1 is provided with illuminating source 5.
The density of site 2 is for increasing gradually by illuminating source 5 density that stretches out.
Improved the utilization factor of light, promoted brightness, the display light of machine, display screen is even.
Principle of work: light inlet side angle degree large (front acute angle 3) utilizes total reflection that light is derived from front, bright dipping side low-angle (rear acute angle 4) transmits light backward, can effectively improve like this utilization factor of light, the brightness that can effectively improve 10%-20% than the brightness of conventional site.
In same face light-emitting area, dot density is larger, and reflection utilization factor is just higher, and brightness is just higher.
The above is only preferred embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
