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/$cm^2$.
