Glass Surface Bump Impact on Performance of Liquid Crystal Displays
The properties of the interior surfaces of a liquid crystal display (LCD) panel have been found to critically influence the display performance. In this article, the glass surface bump at -micron (~10‐6 m) size range in height and -millimeter (~10‐3m) range in width will be evaluated with assembled testing cell. The experimental and simulation results indicated that the surface bump causes cell gap, pretilt angle and twisted angle change. The color gamut and light transmission (gray scale) at normal area and bump area are changed differently with applied voltage. As result, a spot mura could be seen during the panel inspection process at manufacturing plants. The experimental results also show that the most effect region on V-T curve by surface bump is not at the un-driven state or the fully driven regimes of LCDs. Instead, it will happen at intermediate states. The experiments agreed very well with simulation results.
