The Brightness Characteristics of the V- grooved LGPs Carved with Heated Tip

LGP referred as an important component in a back light unit of the LCD. Appropriate cutting conditions of the tip were investigated followed by the LGP was fabricated using the previously optimized tip. The tip was heated to make the V-groove which possessed the depths of tens to hundreds ㎛. The brightness and brightness uniformity characteristics of the LGP fabricated in this experiment were found to be about 20% and 15% higher than that of the commercial products.
