Patent number: 11973261Abstract: An antenna structure with wide radiation bandwidth in a reduced physical space includes a metallic housing, a first feed portion, and a second feed portion. The metallic housing includes a metallic side frame and a metallic back board. The metallic side frame defines a slot, and first and second gaps. The metallic side frame between the first gap and one end of the slot forms a first radiation portion. The second gap divides the first radiation portion into first and second radiation sections. The first feed portion feeds current and signal to the first radiation section, and the first radiation section works in a GPS mode and a WIFI 2.4 GHz mode. The second feed portion feeds current and signal to the second radiation section, and the second radiation section works in a WIFI 5 GHz mode.Type: GrantFiled: January 15, 2021Date of Patent: April 30, 2024Assignee: Chiun Mai Communication Systems, Inc.Inventors: Kun-Lin Sung, Yung-Chin Chen, Yi-Chieh Lee

Patent number: 11955054Abstract: A device may include a display that display an image frame that is divided into adjustable regions having respective resolutions based on compensated image data. The device may also include image processing circuitry to generate the compensated image data by applying gains that compensate for burn-in related aging of pixels of the display. The gains are based on an aggregation of history updates indicative of estimated amounts of aging associated with pixel utilization. The circuitry may generate a history update by obtaining boundary data indicative of the boundaries between the adjustable regions, determining an estimated amount of aging, and dynamically resampling the estimated amount of aging by resampling a portion of the estimated amount of aging corresponding to an adjustable region by a factor and resampling of a different portion of the estimated amount of aging corresponding to another adjustable region by a different factor based on the boundary data.Type: GrantFiled: September 20, 2022Date of Patent: April 9, 2024Assignee: Apple Inc.Inventors: Jim C Chou, Shereef Shehata, Yung-Chin Chen

Patent number: 11908376Abstract: A compensation system includes a processor configured to determine compensated data for display on a sub-pixel of the display device. The processor may receive image data configured to be displayed on the sub-pixel, convert the gray level data to first voltage data; fetch, from a memory, compressed 1×1 sub-pixel uniformity compensation data for the sub-pixel, and decompress the compressed 1×1 sub-pixel uniformity compensation data via a decompressor. The decompressed data comprises the 1×1 sub-pixel uniformity compensation data for the sub-pixel. The processor may also determine a voltage compensation offset value associated with the sub-pixel based on the second voltage data, generate compensated voltage data based in part on the voltage compensation offset value and the first voltage data, convert the compensated voltage data to compensated gray level data; and transmit the compensated gray level data to pixel driving circuitry associated with the sub-pixel.Type: GrantFiled: March 31, 2022Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Lingtao Wang, Giovanni Carbone, Chaohao Wang, Enkhamgalan Dorjgotov, Sheng Zhang, Jim C Chou, Shereef Shehata, Yung-Chin Chen
