Abstract
AbstractAn excimer‐laser‐based two‐shot sequential lateral solidification (TS‐SLS) process has been developed to fabricate 30” FHD (1920×RGB×1080) AMOLED TVs using both 2D projection and line‐scan SLS systems. We have optimized (1) the microstructure of TS‐SLS processed polycrystalline materials, (2) the geometry of driving TFTs to minimize non‐uniformity of the pixel brightness and (3) the off‐bias TFT aging process to reduce the leakage current. This result verifies that the TS‐SLS process can be utilized to make large area AMOLED TVs without any laser related mura.
