Abstract: The present disclosure provides a quantum dot-based display panel, a method and a display device. A pixel of the display panel includes four sub-pixels of R, G, B and W, each of which uses blue light as backlight, both the red sub-pixel and the green sub-pixel include quantum dots, the blue sub-pixel includes a light transmitting layer, and a white sub-pixel includes a yellow light conversion layer. Quantum dots of the yellow light conversion layer are configured to convert a portion of the blue light to yellow light and at the same time transmit the other portion of the blue light such that the obtained yellow light and the transmitted blue light are mixed to form white light. Thereby, R, G, B and W four-color display based on the quantum dots is realized, which enhances the richness of color, display brightness and resolution, the utilization ratio of backlight.
