摘要: 本研究在探討高功率發光二極體(High Power LED)運用於導光板(Light Guide Plate, LGP)入光側之液晶顯示器(Liquid Crystal Display, LCD)背光模組均勻性改善,在模擬上利用光學分析軟體Trace Pro 3.3進行研究探討,研究中將高功率發光二極體運用於側向式導光板之背光模組(Back Light Module)中,由於高功率發光二極體具有高亮度之特性,導致大部份的光線會集中在入光側,無法均勻散開,所以本研究提出在高功率發光二極體光源與導光板入光側間加入側向反射片,讓光線束先在燈箱中均勻反射,再進入導光板中,此設計將可改善入光側光線集中之現象;而側向反射片模擬結果為,開口寬度A=225~325µm、B=400~500µm,側向反射片與高功率發光二極體間距C=1100~1600µm,反射區域寬度D=2000µm,在此參數下,輝度值可達4000nits,均齊度可達90%以上;在實驗方面,將模擬出之側向反射片加工製作,並且進行反射率測試,以及將側向反射片實際放入背光模組中進行入光側亮點測試,測試結果,亮點面積從77mm^2減小為20mm^2,証實本項研究之可行性。
This invention addresses the brightness uniformity improvement of high power LED illuminating light-guide plate for LCD backlighting modules. The simulated back-lighting module is a high power LED as the light source to illuminate light-guide plate from the edge. Since the high power LED with high intensity characteristic, the illuminating light is not spread into the light-guide plate. This invention proposes to add an edge reflector between the high power LED and light-guide plate. This invention can improve the brightness uniformity of backlighting modules. In the experiment, the simulation and fabrication of edge reflector were completed. A back-lighting module to prove the brightness uniformity improvement was assembled. The bright spot area was decreased from 77 mm^2 to 20 mm^2. It shows that the invention is feasible.
