Title: QUANTUM DOT LIGHT-EMITTING DIODE DISPLAY PANEL, PREPARATION METHOD THEREFOR, DISPLAY DEVICE
Abstract:
Provided is a quantum dot light-emitting diode display panel. The display panel comprises a TFT array substrate (1) and multiple pixel structures (2) disposed on the TFT array substrate (1) in an array manner. The display panel is characterized in that each pixel structure (2) comprises a first electrode (21), a cavity transmission function layer (22), a quantum-dot luminescent layer (23), an electronic transmission function layer (24) and a second electrode (25) that are successively laminated along a direction distant from the TFT array substrate (1). The quantum-dot luminescent layer (23) comprises an organic solvent material and quantum dot materials dispersed in the organic solvent material, and the quantum dot materials emit light in the condition electricity excitation. Also provided is a preparation method for the quantum dot light-emitting diode display panel. The quantum-dot luminescent layer (23) in each pixel structure (2) is prepared and obtained and by means of a coating technology.
