Abstract
The invention provides a quantum dot display panel. The quantum dot display panel comprises a pixel layer, a color filter layer, a reflective optical filter layer and a circular polarizer which are arranged in a laminated mode. Two of every three sub-pixels in the pixel layer are filled with red quantum dots and green quantum dots; the color filter layer comprises a color filter, and the color filter comprises a red filter corresponding to the red quantum dots and a green filter corresponding to the green quantum dots; the reflective optical filter layer comprises a reflective optical filter,and the reflective optical filter comprises at least one first film and at least one second film. When the quantum dot display panel displays in a dark state, the quantum dot display panel prevents the quantum dots from being excited by ambient light, also eliminates the ambient light reflected by the metal electrode in the backlight source, and maintains the contrast of the quantum dot display panel.
Description
technical field [0001] The invention relates to the technical field of quantum dot display panels, in particular to a quantum dot display panel optical filter. Background technique [0002] Quantum dots (quantum dot, QD) are tiny semiconductor particles at the nanometer scale, whose optical and electronic properties are different from larger general particles due to quantum mechanics. When the quantum dots receive external light, the electrons in the quantum dots will be excited, and the electrons will jump from the valence band to the conduction band. When the excited electrons return to the valence band again, they will release their energy with light emission. This is the so-called photo-emissive quantum dot. In addition, the quantum dots will also receive the energy provided by the electric field to generate light, which is the so-called electro-emissive quantum dots. [0003] The size of quantum dots affects their light-emitting properties. Larger quantum dots, with ...
