20250178948. Reduced Optical Transmitt (CORNING INCORPORATED)
REDUCED OPTICAL TRANSMITTANCE GLASSES FOR EMISSIVE DISPLAYS
Abstract: glasses are disclosed which can be used to produce glass articles, e.g., glass substrates, for flat panel display devices. the glasses may be substantially alkali free. the glasses are doped with one or more transition metals (e.g., ni, co) and exhibit reduced optical transmittance to suppress light leakage from the display device and/or to improve contrast. the display device may be a bottom emission display device or a top emission display device. the display device may be a tiled display device. glasses disclosed herein may be used, for example, as a baseplate having a plurality of display substrates disposed thereon, a display substrate (e.g., backplane) having a plurality of light emitters disposed thereon, a glass cover plate, or combinations thereof.
