Patent number: 11990836Abstract: A power supply system with dynamic current sharing includes a current-sharing bus and a plurality of power supply units connected to each other through the current-sharing bus. The current-sharing bus provides a first current signal. Each power supply unit includes a local current bus for providing a second current signal. The active current-sharing unit compares the first current signal with the second current signal to generate a compensation voltage. The current-averaging unit compares a difference value between an average value of the first current signal and an average value of the second current signal to generate an average voltage. The droop current unit receives the second current signal to generate a droop compensation voltage. The integration calculation unit makes output currents of the power supply units be approximately equal according to the compensation voltage, the average voltage, and the droop compensation voltage.Type: GrantFiled: April 5, 2022Date of Patent: May 21, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Chi-Hung Lin, Guo-Hua Wang, Yu-Jie Lin, Hsien-Kai Wang

Patent number: 11968856Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.Type: GrantFiled: October 4, 2021Date of Patent: April 23, 2024Assignee: Applied Materials, Inc.Inventors: Chung-Chih Wu, Po-Jui Chen, Hoang Yan Lin, Guo-Dong Su, Wei-Kai Lee, Chi-Jui Chang, Wan-Yu Lin, Byung Sung Kwak, Robert Jan Visser

Patent number: 11956994Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.Type: GrantFiled: August 10, 2021Date of Patent: April 9, 2024Assignee: Applied Materials, Inc.Inventors: Chung-Chih Wu, Hoang Yan Lin, Guo-Dong Su, Zih-Rou Cyue, Li-Yu Yu, Wei-Kai Lee, Guan-Yu Chen, Chung-Chia Chen, Wan-Yu Lin, Gang Yu, Byung-Sung Kwak, Robert Jan Visser, Chi-Jui Chang
