Abstract: Disclosed is an LED light-incident method of an edge-lit backlight module. Light emitted by an is converged by a lens or a lens group that is arranged between the LED and a light guide structure, and then enters the light guide structure. When a thickness of the LED is larger than that of the light guide structure, the light emitted by the LED can completely enter the light guide structure after being converged, so that requirement of reducing a thickness of the light guide structure can be satisfied, and meanwhile light utilization efficiency can be ensured.

Abstract: The invention provides an LCD device, with both the upper polarizer and the lower polarizer having a multi-layer film structure, and comprising a plurality of stacked polarizing film units, with each comprising at least two layers of material films with different refraction index. The backlight module emits light to shine onto the upper and lower polarizers at a tilt angle, and the light is reflected and refracted a plurality of times at the interfaces inside the multi-layer film structure, and the S-polarized light and P-polarized light are separated completely to form linearly polarized light. Only the P-polarized light can pass. Compared to the conventional absorbing polymer polarizer, the upper and lower polarizers use a multi-layer film structure and the backlight module emitting light at a specific angle, so that the upper and lower polarizers provide high temperature stability, high humidity stability and high reliability, and simple to manufacture.
