Description

technical field

[0001] Embodiments of the present invention generally relate to the field of display devices, and in particular, relate to a method for manufacturing a quantum dot light emitting diode sub-pixel array, a quantum dot light emitting diode sub-pixel array manufactured thereby, and a display device including the quantum dot light emitting diode sub-pixel array. Background technique

[0002] Active-matrix organic light-emitting diodes (AMOLEDs) were once recognized as promising next-generation display products to replace liquid crystal displays (LCDs). However, with the improvement of consumers' consumption level, high-resolution products have become the key development direction of display products, and it is difficult for high-resolution AMOLED products to compete with LCD, because the organic layer structure of organic light-emitting display products usually adopts a mask However, the mask evaporation method has defects such as difficult alignment, low yield, a...
