Development of world's largest 21.3” LTPS LCD using sequential lateral solidification (SLS) technology

Abstract The world largest 21.3” LTPS LCD has been successfully developed using SLS crystallization technology. Integration of gate circuit, transmission gate and level shifter was successfully performed in a large area display. Uniform and high performance of high quality grains of SLS technology make it possible to realize a uniform large size LTPS TFT‐LCD with half the number of data driver IC's that is typically used in a‐Si LCD. High aperture ratio of 65 % was achieved using an organic inter insulating method which lead to a high brightness of 500 cd/cm2.
