Embodiment Construction

[0032] As mentioned in the background section, the printing fineness of the 3D printing system in the prior art is relatively low.

[0033] The inventors found that the reason for the above phenomenon is that the 3D printing system in the prior art usually uses a liquid crystal display panel as a photomask, please refer to figure 1 and figure 2 , figure 1 is a schematic cross-sectional view of a display panel in the prior art; figure 2 It is a schematic diagram of a top view structure of a display panel in the prior art.

[0034] The liquid crystal display panel includes a first substrate 01 and a second substrate 02 oppositely arranged, and a plurality of spacers 03 are arranged between the first substrate 01 and the second substrate 02 for supporting the display panel. Among them, the plurality of spacers 03 includes a plurality of main spacers 031 and a plurality of auxiliary spacers 032, the height of the main spacers 031 is larger than the height of the auxiliary spa...

Abstract

The present application provides a display panel and a 3D printing system. The display panel includes a main spacer and an auxiliary spacer, and a black matrix. The black matrix includes a first shielding part and a second shielding part. The first shielding part is used to shield the main The spacer, the second shielding part is used to shield the auxiliary spacer, wherein the pixels overlapping with the first shielding part are the first pixels, and the pixels not overlapping with the first shielding part are the second pixels, and the second shielding part The portion includes a first sub-second shielding portion, and an overlapping area of ​​the first sub-second shielding portion and the first pixel is smaller than an overlapping area of ​​the first sub-second shielding portion and the second pixel. By reducing the overlapping area of ​​the first sub-second shielding part and the first pixel, increasing the area of ​​the opening area of ​​the first pixel, so that the difference between the aperture ratio of the first pixel and the aperture ratio of the second pixel is reduced, so that the display The light transmittance of the first pixel and the second pixel in the panel are the same, thereby improving the fineness of 3D printing.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a 3D printing system. Background technique [0002] 3D printing technology drives intelligent manufacturing, greatly improves the production efficiency of traditional manufacturing, and greatly simplifies the manufacture of complex samples. The application in fields such as parts processing and manufacturing is gradually deepening, and the market prospect is very promising. [0003] Stereo Lithography Apparatus (SLA) is a widely used 3D printing technology at present. In this method, a laser with a specific wavelength and intensity is focused on the surface of the photocurable material, making it from point to line, and then from line to line. The surface is sequentially solidified to complete the drawing operation of one layer, and then the lifting platform moves the height of one layer in the vertical direction, and then solidifie...
