Abstract

The invention provides a quantum dot display panel and a three-dimensional printing apparatus. The quantum dot display panel is composed of a substrate, a control circuit layer, a pixel definition layer, and a plurality of light-emitting units. The control circuit layer arranged at one side of the substrate includes a plurality of control circuits. The pixel definition layer and the plurality of light-emitting units are arranged at one side, far away from the substrate, of the control circuit layer; the pixel definition layer includes a plurality of openings; and the plurality of light-emitting units are arranged in the openings. The control circuit is connected with the plurality of light-emitting units electrically and is used for controlling light-emitting states of the light-emitting units; each light-emitting unit consists of a first electrode, a quantum dot light-emitting layer, and a second electrode successively in a direction away from the substrate; and light emitted by eachlight-emitting unit has the wavelength of 350nm to 450nm. With the quantum dot display panel and the three-dimensional printing apparatus, the dark-state brightness of the display panel is reduced, sothat a problem of light sensitivity of the resin corresponding to a non-effective graphic is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot display panel and a three-dimensional printing device. Background technique [0002] Rapid prototyping technology, also known as three-dimensional printing (3D printing), is a high-tech manufacturing technology based on material accumulation method. According to the three-dimensional model data of parts or objects, physical objects or Mock-up. Due to the advantages of greatly reducing production costs, improving the utilization of raw materials and energy, customizing according to needs, and greatly saving product production time, 3D printing technology has gradually entered the public eye and developed rapidly in recent years. [0003] The basic principle of 3D printing is layered processing and superimposed molding, that is, to generate 3D entities by adding materials layer by layer. When 3D printing is performed, the computer first obtains the 3D model of the o...
