Abstract
Two types of display defects were found at special positions near the pixel indium tin oxide (ITO) edge in the multi-domain vertical alignment (MVA) mode liquid crystal display (LCD). Through simulated and experimental results, the formation mechanisms of these two types of display defects, the detailed configurations of liquid crystal (LC) orientations at the display defect regions and the principle to suppress the defect dark line were analyzed and discussed. It was further found that the occurrence of the dark line was related to the positioning accuracy of substrate assembly. The reason of the dark line occurrence related with the positioning accuracy and the manufacturing margin were provided here.
