A 118 cm(47 in) LED backlight was designed with reasonable selecting sheets and optimizing the mechanical structure. To ensure the brightness of backlight
a piece of diffusion sheet
two pieces of prism sheets and a piece of DBEF were combined. And the distance between LED and LED
the gap between LED and LGP
were determined by a series tests. Then according to the tests results
118 cm(47 in) LED backlight sample was assembled. Comparing with other products
the module has the lowest power consumption than others with the same optical performances.
