Abstract
The invention provides a backlight module which comprises a light-emitting layer and a brightness enhancement layer, and the brightness enhancement layer is arranged on the surface of the light-emitting layer. The brightness enhancement layer comprises a plurality of optical micro-cavities, and each optical micro-cavity is used for enabling light emitted into the light-emitting layer to generate resonance to obtain resonance light and emitting the resonance light out. According to the backlight module provided by the invention, the brightness enhancement layer is arranged on the surface of thelight-emitting layer; the brightness enhancement layer is designed to be of an optical micro-cavity structure, the intensity of part of light emitted into the optical micro-cavity by the light-emitting layer is greatly enhanced and emitted out based on the WGM resonance effect and the antenna effect of the optical micro-cavity, and therefore the light-emitting brightness of the light-emitting layer is greatly improved. The invention further provides a display device with the backlight module.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display device with the backlight module. Background technique [0002] Mini Light Emitting Diode (Mini-LED) is a light-emitting device obtained by miniaturizing the size of traditional LEDs. Compared with traditional LEDs, it is smaller in size, so if it is used in displays , the resolution of the display screen can be increased. [0003] Usually, the Mini-LED is used as a backlight and combined with a Liquid Crystal Display (LCD) panel to form an LCD display. In order to improve the contrast of the display screen, it is necessary to increase the luminous brightness of the Mini-LED. In the prior art, the reflective method is usually used Improve the luminous brightness of the Mini-LED, but this method has a limited effect on improving the luminous brightness of the Mini-LED. Contents of the invention [0004] Therefore, it is necessary to ...
