Background technology
Mobile phone mobile phone, or be radio telephone, commonly referred to as mobile phone, it is a kind of communication tool originally, early stage is again
There is being commonly called as mobile telephone, be the portable telephone terminal that can be used in the broader context, is by AT＆T Labs of the U.S. earliest
The battlefield mobile phone manufactured in 1940 develops.
The row of Soviet Union engineer in 1958 hold high Maimonides Ku Puliyang Milunovich and have invented Л К -1 type mobile phones, 1973 years
Motorola of U.S. engineer Martin library pa has invented first commercialization mobile phone in the world.When being developed to 4G so far
Dai Liao.
Light guide plate (light guide plate) is acrylic/PC plate material using optical grade, then high anti-with having
Rate and the not hitech materials of extinction are penetrated, carve in the acryl plates bottom surface laser engraving of optical grade, V-type cross grid,
UV screen printing technologies stamp light guiding points.The light issued from lamp is drawn in optical grade acrylic using optical grade acryl plates
The stop of plate surface, when light is mapped to each light guiding points, reflected light can be spread toward all angles, then destroy conditioned reflex
It is projected by light guide plate front.By various densitys, light guiding points not of uniform size, light guide plate uniformly light-emitting can be made.The use of reflector plate
Way is that the light reflection for exposing bottom surface is returned in light guide plate, for improving the service efficiency of light;With homalographic light emission luminance situation
Under, luminous efficiency is high, low in energy consumption.
Point light source or linear light source emit beam into propagating in light guide plate, by light guide plate with optical texture design
Bottom surface and reflecting plate make light diffusion project, and are evenly distributed in light-emitting zone, to coordinate the optical characteristics of liquid crystal display
It is required that.When more smooth due to the surface of light guide plate, light is easily set to generate scattering phenomenon, and in turn to the visual angle of image and light
The uniformity generates image.Therefore, the bottom or top of part light guide plate are provided with multiple micro-structures, to lower light in leaded light
The scattering phenomenon that plate surface generates, and promote whole outgoing light homogeneity and radiance degree.
Indispensable component during light guide plate is produced as mobile phone has higher requirement to the quality of light guide plate.It is guide-lighting
Loss of the light source of plate in conductive process is more serious, and the conductibility of light is bad, and hardly possible has the condition of batch production, and processing is wanted
It asks and increases, cause to process complex, difficulty of processing is larger.
