A novel Black Photo Spacer (BPS) structure is demonstrated in this present work. The black BPS material supports the substitution of black matix (BM) to realize shading function. Thus the BPS technology can integrate BM into PS process, which saves the material, mask, machine and time cost. In order to improve stability, we use full tone mask design. Different height (ΔH) of Main PS and Sub PS are generated by color filter stacking. Polymer film on array (PFA) is used to reduce the excessive primary height between Main PS and Sub PS. In addition, all the patterns included color filter, BM and PS are on array side, which can effectively avoid the backlight leakage and enhance contrast ratio (CR). More discussions of the designs, process and optical performances about 1‐tone BPS such as Data line BM less (DBS) are demonstrated in this paper, and a 28 inch demon with this BPS technology is shown at the end.
