For narrow border TFT-LCD TV ( < 1 mm border), we propose a glass diffuser plate (GDP) by using Corning Eagle XG ™ with a bottom cut structure to reduce light leakage in larger viewing angle. The reasons why Corning’s GDP are helpful to improve cosmetic issue. First, Corning provides precise cutting tolerance (± 0.1 mm) of GDP size to narrow gap. Second, the bottom cut edge finishing could enables light leakage reduction (~40%) compared to no edge chamfer. In addition, by simulation, this paper also discusses the effect of GDP size control, GDP thickness and GDP lamination length with optical films on light leakage improvement.
