Problems solved by technology

However, although this method can improve the display color gamut of the OLED display panel, because the quantum dot film emits light from nanoparticles, its light emission angle is relatively scattered, and the emitted light of different colors will overlap and interfere with each other, reducing the color of the OLED display panel. purity

Abstract

The embodiment of the invention provides a display panel. The display panel comprises a plurality of pixel units, and each pixel unit comprises a red area, a green area and a blue area; the display panel comprises a substrate, a blue light-emitting device, a packaging layer and a quantum dot film, the quantum dot film comprises a red quantum dot color area, a green quantum dot color area and a light-transmitting area, the red quantum dot color area is located in the red area, the red quantum dot color area emits red light under excitation of blue light emitted by the blue light-emitting device, the green quantum dot color area is located in the green area, the green quantum dot color area emits green light under excitation of blue light emitted by the blue light-emitting device, the light-transmitting area is located in the blue area, and the light-transmitting area is configured to transmit the blue light emitted by the blue light-emitting device; and the display panel further comprises a light conversion layer arranged between the packaging layer and the quantum dot film. Red light and green light which are emitted downwards are converted into blue light through the light conversion layer, so that superposition and interference between different colors of light emitted by the quantum dot film are reduced, and the color purity of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Organic Light Emitting Diode (OLED) has many advantages such as self-illumination, high brightness, high contrast, fast response, wide viewing angle, simple structure, and flexible display. It has attracted universities and enterprises because of its excellent performance. Favored by the rapid development, and widely used in display products. [0004] In related technologies, in order to increase the display color gamut of the OLED display panel, the OLED display panel uses quantum dots (Quantum dot) to make a color film (Color Film, CF for short) layer, which is to form a quantum dot film, so that the blue light can be emitted The luminescent layer emits light to excite the quantum dots in the c...
