Transmissive liquid crystal panel and 3D printer
Transmissive liquid crystal panel and 3D printer including the same, the panel includes: a first substrate including a plurality of data lines and scan lines, data lines intersecting with scan lines to define a plurality of pixels; a second substrate; a liquid crystal layer located between the first and second substrate; a black matrix defining a plurality of aperture areas corresponding to the pixels; a monochromatic quantum dot layer covering the aperture areas, the monochromatic quantum dot layer being excitable under near ultraviolet light to generate light having a wavelength in a range of 385 nm-420 nm. The panel does not use chromatic filter layer, which improves transmittance of the panel with respect to near ultraviolet light, when the panel is applied in 3D printer, photographic efficiency of photosensitive resin and printing speed are improved, and utilization of near-ultraviolet light emitted by the backlight source is improved.
