We proposed a new type backlight model that offered oblique incident light source. An optical software (Trace Pro TM) was utilized to simulate the backlight model design. We added a focusing foil upon the light guide plate and combined vertex angles for the focusing foil, and then characterized the relationship between the vertex angles and exit angle. The simulation results showed as follows. 1. The light is able to be focused at two directions as the vertex angles are identical on the both sides. 2. Two concentrated lights symmetrical distribution at exit surface as the vertex angles are identical on the both sides 3. The space between two concentrated lights decreased with the vertex angles increased. 4. Two concentrate lights percentage of total lights increased with the vertex angles increased.
