The light-emitting device provided by the present invention includes a first light source, a second light source, a dichroic mirror, a wavelength conversion device, a first optical path adjustment device or a second optical path adjustment device, and a first scattering optical system. In the present invention, the light mixing effect of the emitted light can be improved by using the first scattering optical system. The color temperature of the emitted light of the light-emitting device can be freely adjusted by adjusting the power of the first light source and the second light source separately. A laser that can emit light of different main wavelengths can also be used in the second light source to improve the color rendering index of the emitted light of the light-emitting device. The light emitted by the first light source in the present invention is all used to excite the wavelength conversion device. Compared with the prior art solution, the light-emitting device provided in the present invention can achieve a higher luminous flux output without increasing the optical extension. If a polarization selection element is used in the first light source, the luminous flux output of the light-emitting device can be further improved.

Light-emitting substrate, backlight module and display device

ActiveCN119882306Bextended pathImprove light mixing effectNon-linear opticsDisplay deviceHemt circuits
The application discloses a light-emitting substrate, a backlight module and a display device, and belongs to the technical field of display. The light-emitting substrate provided by the application comprises a back plate, a driving circuit layer and a plurality of light-emitting units. The light-emitting unit comprises a reflecting layer, a paving layer and a light-emitting chip. Since the light-emitting surface of the light-emitting chip faces the reflecting layer, the light emitted by the light-emitting chip is first transmitted to one side of the back plate, and then is reflected by the reflecting layer arranged on the inner wall of the counterbore on the back plate, so that the path of the light emitted by the light-emitting chip is prolonged. In this way, after the light-emitting substrate is integrated in the backlight module, the distance between the light-emitting substrate and the diffusion plate in the backlight module does not need to be increased, the backlight module can have a better light mixing effect, and the overall thickness of the backlight module is relatively low.
