With LED selected as the light source of side-incident light guide plates
it solves the difficult problems with the design of scattering netted dots with various distances on light guide plates of side-incident LED backlight efficiently by deriving a rule of scattering netted dots arrangement
based on the optics theories such as total reflection
refraction and the principle of luminous flux conservation. The critical array pitch of LED is deduced
which can effectively eliminate the different light intensity caused by LED arrays. Then
the optical design software TracePro was used to establish the physical simulation model. Through repeated experimental investigation
optimum parameters have been obtained. The simulation results show that the illumination uniformity of the designed light guide plate is close to 93%(over 80%)
which satisfies the requirements of the national illumination standard.
