DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/166025
Kind Code:
A1
Abstract:
A display device, comprising a display panel (10) and a backlight source (20), wherein the display panel (10) comprises an upper substrate (11) and a lower substrate (12) that are arranged opposite each other; a reflective filter layer (111) and a colour light-emitting layer (112) are arranged on the upper substrate (11); and the reflective filter layer (111) transmits the red, green and blue light emitted from the colour light-emitting layer (112), and reflects some of the light rays emitted from the backlight source (20) to the colour light-emitting layer (112), so as to excite the colour light-emitting layer (112) to emit light again. The efficiency for solar energy utilisation of the backlight source (20) and the luminous efficiency of the colour light-emitting layer (112) are improved, and the content of quantum dots in the colour light-emitting layer (112) is reduced with little or no impact on the light-emitting effect, thereby reducing the content of cadmium in the quantum dots, so as to conform to standard requirements.
