摘要

A conventional backlight unit (BLU) is utilized to as the light module to present uniform light of liquid crystal display (LCD). In general, cold cathode fluorescent lamp (CCFL) is used to be the light source of BLU. The light emitting diode (LED) is well known as a promising device for solid state lighting. It has the advantages of long life, no mercury containing and good endurance of heavy impact. To satisfy the market demands of the thin-film liquid crystal display (LCD) and the green product, the LED is applied to as the light source to make display thinner, lighter, no Hg containing. In this research, the LED light-linear device with microprism structure is demonstrated that it can make the point-like light to distribute propagating-light line pattern successfully. By optimizing the distributions and sizes of microprisms, the designed LED-linear device can achieve an illuminative efficiency more than 80%～90%, and its light output area is two times the input light source. Thus, the LED light-linear device with microprsims not only can decrease the LED to save the space, but also increase the optical efficiency. In future, a novel LED light module could make displays thinner and lighter for light guide plate (LGP) applications.
