Problems solved by technology

In the prior art, the lower polarizer is generally an absorbing polarizer. When the unpolarized light emitted by the backlight passes through the lower polarizer, the component in the direction of the absorption axis of the lower polarizer will be absorbed and cannot pass through. Therefore, the light transmittance of the lower polarizer to the backlight produced by the backlight module is theoretically no more than 50%, and after the light passes through the liquid crystal panel, the user can actually see the brightness of the liquid crystal display generally not exceeding the brightness of the backlight. The module emits 10% of the brightness of the backlight, which makes the utilization rate of the backlight quite low and causes energy waste

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Wherein, the accompanying drawings are only used for exemplary illustration, and represent only schematic diagrams, and should not be understood as limitations on this patent.

[0020] see figure 1 , the present invention provides a liquid crystal display 100 . The liquid crystal display 100 includes a backlight module 10 , a quantum rod film 20 , a lower polarizer 30 , a liquid crystal panel 40 and an upper polarizer 50 stacked in sequence. The quantum rod film 20 is located between the lower polarizer 30 and the backlight module 10 . The backlight generated by the backlight module 10 enters the liquid crystal panel 40 through the quantum rod film 20 and the lower polarizer 30, and then emits light through the upper polarizer 50, thereby completing the liquid crystal display ...

Abstract

The invention provides a liquid crystal display. A quantum rod film is arranged between a lower polaroid and a backlight module. Backlight generated by the backlight module is absorbed firstly by a quantum rod on the quantum rod film, and then, a polarized light of which the emergent direction is same as the alignment direction of the quantum rod exits. As the alignment direction of the quantum rod is same as the polarization axis direction of the lower polaroid, the backlight penetrating through the quantum rod film can largely penetrate through the lower polaroid, light rays absorbed by the lower polaroid are reduced, light transmittance of the lower polaroid to the backlight generated by the backlight module is increased, and the utilization rate of the backlight is increased, and then, brightness of the liquid crystal display is increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display. Background technique [0002] The liquid crystal display includes a liquid crystal panel and a backlight module arranged in layers, and a lower polarizer is provided between the liquid crystal panel and the backlight module, so that the backlight generated by the backlight module is incident to the said backlight module according to a certain polarization direction. in the LCD panel. In the prior art, the lower polarizer is generally an absorbing polarizer. When the unpolarized light emitted by the backlight passes through the lower polarizer, the component in the direction of the absorption axis of the lower polarizer will be absorbed and cannot pass through. Therefore, the light transmittance of the lower polarizer to the backlight produced by the backlight module is theoretically no more than 50%, and after the light passes through the...
