Abstract

The invention provides a backlight generating device and display equipment. The backlight generating device comprises a red light vertical cavity surface emitting laser device, a green light vertical cavity surface emitting laser device and a blue light source, wherein the blue light source is arranged between the red light vertical cavity surface emitting laser device and the green light vertical cavity surface emitting laser device, and the light emitting surfaces of the red light vertical cavity surface emitting laser device, the green light vertical cavity surface emitting laser device and the blue light source face the same side. According to the invention, the backlight generating device comprises the red light vertical cavity surface emitting laser device, the green light vertical cavity surface emitting laser device and the blue light source, the red light vertical cavity surface emitting laser device and the green light vertical cavity surface emitting laser device are high in color radiation energy and narrow in half-wave width, the blue light source is mixed with the red light vertical cavity surface emitting laser device and the green light vertical cavity surface emitting laser device, and blue, red and green colors are pure, so that the color gamut can be improved.

Description

technical field [0001] The present application belongs to the field of display technology, and more specifically, relates to a backlight generating device and a display device. Background technique [0002] Some display screens often use LED backlight as the light source. The principle of LED light emission is to excite phosphor powder with blue light to emit red light and green light, which are mixed to generate white light. Phosphor powder is a kind of composite material, the red light and green light emitted have wide peaks, the radiant energy is not strong, and the red and green are impure, resulting in a low color gamut, in some cases, the color gamut is only 70%, which affects the display performance. Color display quality. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a backlight generating device and a display device, so as to solve the technical problem of the low color gamut of the display screen exist...
