Light guide plate and backlight module using the same |
摘要 |
A light guide plate includes an emitting surface; a reflective surface opposite to the emitting surface; an incident surface interconnecting with the emitting surface and the reflective surface. A plurality of ridges are formed on the reflective surface. Each ridge has a first base angle and a second base with respect to the reflective surface. The first base angle closest to the incident surface is in a range from about 86 degrees to 90 degrees. The second base angle furthest from the incident surface is in a range from about 41.8 degrees to 45.8 degrees. A backlight module using the light guide plate is also provided. The present light guide plate and a backlight module using the same can efficiently increase light brightness.
