Abstract

The invention discloses a self-light emitting display structure. The structure includes a first substrate, a first electrode arranged on the first substrate, a second electrode arranged on the first electrode, a light emitting layer disposed between the first electrode and the second electrode, a quantum dot layer which is arranged on the second electrode and comprises at least one quantum dot film, and a first polymer film arranged on the quantum dot layer. The self-light emitting display structure is advantaged in that the first polymer film is arranged on the quantum dot layer, so excitation photons which pass through the quantum dot layer but are not absorbed can be reflected back again, so quantum dots can be excited again, the photon recovery function is added, excitation efficiencyof the quantum dots is improved, light emitting efficiency of the whole system is improved, and the display effect is improved.

Description

technical field [0001] The invention belongs to the field of display panels, and in particular relates to a self-luminous display structure and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is a flat panel display technology with great development prospects. It not only has excellent display performance, but also has self-illumination, simple structure, ultra-thin, fast response, wide viewing angle , low power consumption and flexible display can be realized. [0003] At present, the existing technology provides a kind of blue-light OLED to excite red or green quantum dots to make them emit light to obtain the three primary colors of red, green and blue to realize color display. This technology needs to uniformly mix a certain amount of quantum dots (QUANTUM DOT) into the dispersion material, however, this will cause problems of insufficient light absorption (light leakage) and a decrease in luminous efficiency.
