Abstract

The present invention provides a quantum dot display panel and a three-dimensional printing device. The quantum dot display panel includes: a substrate; a control circuit layer located on one side of the substrate, and the control circuit layer includes a plurality of control circuits; a pixel definition layer and A plurality of light-emitting units are located on the side of the control circuit layer away from the substrate; the pixel definition layer includes a plurality of openings, and the plurality of light-emitting units are respectively located in the openings; the control circuit is electrically connected to the light-emitting A unit for controlling the light-emitting state of the light-emitting unit; any of the light-emitting units sequentially includes a first electrode, a quantum dot light-emitting layer, and a second electrode in a direction away from the substrate; the light emitted by the light-emitting unit The wavelength is between 350nm and 450nm. The invention provides a quantum dot display panel and a three-dimensional printing device to reduce the brightness of the display panel in a dark state and solve the problem of photosensitive resin corresponding to the non-effective pattern area.

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...
