摘要:
An exemplary light emitting diode (LED) includes an LED chip and a transparent sealant covering the LED chip. The sealant contains transparent filling particles and phosphor particles, wherein the filling particles are adjacent each other. Intervals are defined between the filling particles, and the phosphor particles are located in the intervals.

An exemplary backlight module (1) includes a reflective polarizer sheet (10), a diffusing sheet (11), and a reflective sheet (14). The reflective polarizer sheet includes a light incident surface (102), a light emitting surface (104) opposite to the light incident surface, and a plurality of prism structures (106) at the light emitting surface. The diffusing sheet is adjacent to the light incident surface of the reflective polarizer sheet. The reflective sheet is below the diffusing sheet. The backlight module has a high brightness and an improved light utilization ratio with a low cost and a reduced thickness.
摘要:
A light guide plate (200) includes at least one surface through which light beams pass, at least one translucent ink film (220) disposed on the at least one surface through which light beams pass, and the at least one translucent ink film includes a plurality of pigment particles (221). The pigment particles of the translucent ink film can absorb red light and green light, and thereby compensate for a shift in chromaticity that would otherwise occur in a backlight module due to absorption of blue light in the optical sheets of the backlight module. Therefore degradation of the display quality of the LCD is reduced or even eliminated.
