  • Abstract For Liquid crystal display (LCD) products that under the needing of characteristics try to get high colors quality, life of products, fast booting and low voltage driven. The manufacturer begins to ponder the substituting light source over the scheme of Cold Cathode Fluorescent Lamps (CCFL), and LED is the most favored use as light sources to next century’s backlight.
    LED is use on backlight source module and often seen it applied in Edge lighting module already (screen of mobile phone, PDA and NB for example). As for LED applied in direct-lighting module design which because of LED with directed light and pointed light characters, raise the bottleneck problem of design can’t achieve color with uniform and the thin thickness of module not easily , so not popularize it until now. This thesis’s research point is use TracePro optical simulation software to execute the simulation of direct-lighting module, analysis and design the best LED Lens structure, through this structure to make light with an even distribute on chamber of backlight module, then achieve the goal that module’s luminance and color even distribution and get thin thickness at same time.
