Abstract

The invention discloses an LED back light module. The module comprises sequentially a light guide plate, a quantum dot color enhancement film, a first bright enhancement film and a second bright enhancement film. The peripheral area of the quantum dot color enhancement film is filmed with light absorbing media. The second bright enhancement film comprises a plurality of lens structure. The lens structure includes a first lens structure located on the peripheral area of the second bright enhancement film and a second lens structure located at the center of the second bright enhancement film. The peripheral area encloses the central area. The light collection performance of the first lens structure exceeds the light collection performance of the second lens structure. Through the high light collection performance of the peripheral area of the second bright enhancement film, the module can enhance the emergent light brightness in the peripheral area, thus modify the problem of relatively low brightness in the peripheral area in comparison with the brightness of the central area of the LED display equipment, enhance the display uniformity of the LED display equipment. An LED display device is also disclosed.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal backlight module and a liquid crystal display device including the liquid crystal backlight module. Background technique [0002] A liquid crystal display device cannot emit light independently, therefore, a backlight source needs to be provided in the liquid crystal display device. [0003] The backlight of liquid crystal display devices generally uses blue light-emitting diodes. In a traditional liquid crystal display device, red and green phosphors are usually covered on the blue light-emitting diode, and the red and green phosphors covered on the blue light-emitting diode can convert the blue light emitted by the blue light-emitting diode into white light. [0004] However, the performance of this traditional liquid crystal display device to improve the color gamut is limited. For example, the color gamut of the traditional liquid crystal disp...
