Problems solved by technology

[0004] Currently, panel makers such as Samsung, BOE, AUO, and CSOT are vigorously developing QD technology. However, the limitations of QD itself and the high-standard development goals make the realization of QD technology difficult.
One of the difficulties is how to achieve >90% BT2020 color gamut, because it is difficult to improve QY and reduce FWHM from the perspective of QD materials

Abstract

The invention provides a display panel and a display device. The display panel comprises a base plate, wherein the base plate is provided with a color film layer; the color film layer is provided witha first color resistor; and a green or red quantum dot is arranged in the first color resistor; and the first color resistor is also provided with a first shading layer, and materials adopted by thefirst shading layer comprise yellow light resistance materials or red light resistance materials. By sue of the display panel and the display device provided by the invention, the color purity of green light or red light emitted after the quantum dot in the color resistor is stimulated can be improved.

Description

technical field [0001] The invention relates to the field of plane display, in particular, a display panel which can be used in plane display devices such as OLED and LCD. Background technique [0002] With the continuous improvement of the market's pursuit of display panel user experience, the development and production of displays with higher color gamut and higher brightness has become the goal pursued by various panel manufacturers in the industry. Among them, the strong attack of OLED technology has made TFT-LCD panels face the risk of being eliminated. How to enhance competitiveness and occupy a place in the market has become the most urgent key point for all panel manufacturers in the industry to think about. [0003] The QD (Quantum Dots, Quantum Dots) material has a wider absorption peak and a narrower emission peak, so that it can show higher purity in color display, so that when it is used in a display device, it can improve the display. The display effect of the...
