Patent number: 12259548Abstract: A light guide substrate, including a light coupling-in region with multiple first gratings, a light expansion region with multiple sub light expansion regions, and a light coupling-out region, is provided. Each sub light expansion region includes multiple second gratings. The sub light expansion regions include a first set of sub light expansion regions and a second set of sub light expansion regions. Each second grating in the first set of sub light expansion regions includes a first microstructure and a second microstructure. The light coupling-out region includes multiple third gratings. When an image light enters the light guide substrate from the light coupling-in region through the first gratings, the image light is first transmitted to the light expansion region in the light guide substrate, then transmitted to the light coupling-out region through the second gratings, and then emitted from the light coupling-out region through the third gratings.Type: GrantFiled: February 8, 2022Date of Patent: March 25, 2025Assignee: ASUSTeK COMPUTER INC.Inventors: Wen-Chang Hung, Yu-Chieh Cheng

Patent number: 10591770Abstract: A display device comprising a color filter layer and a light-emitting unit is provided. The color filter layer includes a first subpixel area, a second subpixel area and a third subpixel area. The first subpixel area includes a first quantum dot material, and the second subpixel area includes a second quantum dot material. The light-emitting unit provides light to the color filter layer. A wide color gamut and a polarization effect are achieved via the quantum dot materials and the polarization material. Furthermore, due to no additional loss of the light at the light-emitting unit (backlight module), the luminous efficiency is high.Type: GrantFiled: April 14, 2017Date of Patent: March 17, 2020Assignee: ASUSTeK COMPUTER INC.Inventors: Chin-An Tseng, Wen-Chang Hung, Yung-Ming Huang, Mien-Mien Cheng, Yi-Ching Chen
