Abstract

The asymmetric prism structure contains multiple asymmetric prisms arranged in parallel where each asymmetric prism has a first slant face, a second slant face, and a bottom face, connected end-to-end together. The first slant face directs light beams propagating perpendicular to the prism direction to a lateral side, and the second slant face directs light beams propagating perpendicular to the prism direction to the other lateral side. The present invention further provides a light guide plate, a backlight module, and a related application utilizing the asymmetric prism structure. When vertical asymmetry is present in the timing sequences for the backlight scanning and the signal to the LCD panel, the asymmetric prism structure can reduce the cross-talk near a side from the error signal, thereby enhancing the video quality.
