Problems solved by technology

However, the energy of blue light photons is relatively high, and it is easy to cause the decay of polymer organic materials in the light-emitting layer, which greatly reduces the service life of active light-emitting display panels.

Abstract

The invention discloses an active light emitting display panel and a manufacturing method thereof. A light emitting layer of the active light emitting display panel is designed to give out red light or green light rather than blue light; and since the energy of red-light photon and green-light photon both are lower than the energy of blue-light photon, the attenuation of a macromolecule organic material in the light emitting layer is difficult to cause, and the service lifetime of the light emitting display panel can be prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an active light emitting display panel and a manufacturing method thereof. Background technique [0002] Active light-emitting display panels, such as display panels with OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) or QLED (Quantum Dot Light Emitting Diodes, Quantum Dot Light-Emitting Diodes) devices, have the advantages of fast response and high contrast. mainstream trends in the field. At present, active light-emitting display panels generally use "OLED or QLED+CF" technology to achieve full-color display. In the pixel area and the green sub-pixel area, the blue light is irradiated to the luminescent CF (Color Filter, color filter), the luminescent CF in the red sub-pixel area emits red light when excited by the blue light, and the luminescent CF in the green sub-pixel area emits red light. The light CF emits green light when excited by blue light, ther...
