Problems solved by technology

Due to the wide spectrum of white light, when using a color filter (CF) to separate white light into RGB three primary colors, the RG spectrum is usually wide and the color purity is low, and the color gamut performance of the panel is difficult to break through the 100 set by NTSC %standard
In addition, when white light is separated into RG spectrum, only a small amount of red or green light in the white light spectrum can be used, and the energy loss of blue and yellow light is relatively large.
Therefore, due to the low energy utilization rate of the existing WOLED, it will cause the problem of high power consumption when the panel is working.

Abstract

A bottom emission white light organic light emitting diode display panel and its manufacturing method, display device, wherein the bottom emission WOLED display panel includes a substrate, a thin film transistor, a WOLED color filter layer, a quantum dot photoelectric conversion layer, a first electrode, a WOLED electric A luminescent functional layer and a second electrode. The WOLED color filter layer is provided with red, green, blue and white pixels in sequence. The quantum dot phototransformation layer includes quantum dot red and green luminescent materials corresponding to the red and green pixels. The WOLED electroluminescent functional layer is arranged on the first electrode. The second electrode is arranged on the WOLED electroluminescent functional layer, and the blue light or yellow light of the WOLED electroluminescent functional layer is converted into red by the quantum dot red-green luminescent material of the quantum dot phototransformation layer. light and green light, so as to increase the brightness of the red pixel and the green pixel, so as to improve the color gamut performance of the bottom emission WOLED display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a bottom emission white light organic light emitting diode (WOLED) display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (OLED) is a new type of display technology. Compared with LCD display technology, it has active light emission, true color, infinite contrast, zero delay, transparent display, flexible display, free-form display (Free-Form D insulation It is a next-generation display technology that can replace liquid crystal display technology. Since OLED display technology does not require a backlight source, its structure is simpler than that of LCD, and the volume of display products can be made lighter and thinner. White organic light-emitting diodes (WOLED) are mainly used in large-size panel display technology. WOLED technology is different from the side-by-side (side-by-side) RGB technology wide...
