In this study, we have developed high performance TFT (thin film transistor) and a 7.4-inch high resolution LCD (liquid crystal display) panel of full color WSXGA (1600×RGB×1024, 257ppi, 43% aperture ratio) format using ‘sequential lateral solidification (SLS)’ laser crystallization process [Y.J. Kim et al., Grain boundary effect on the characteristics of the high-performance poly-Si TFTs crystallized...
By the integrated drive circuitry with laser crystallization process, the gate and data driver circuits required for full color WVGA(800×RGB×480) LCD are integrated on panel. The integrated driver comprises a sequential analog sampling data driver and a dual logic gate scanner for redundancy. The characteristics and uniformities of the LTPS (low temperature polycrystalline silicon) devices have been...
