Patent number: 9618807Abstract: Methods and devices to compensate for image color variance due to display temperatures are provided. In one example, a display of an electronic device may include a first pixel section that has multiple pixels. The pixels may include a red subpixel, green subpixel, and blue subpixel that each has a respective aperture ratio. The display may also include a second pixel section that has multiple pixels. Again, the pixels may include a red subpixel, green subpixel, and blue subpixel that each has a respective aperture ratio. One or more of the subpixel aperture ratios of the first pixel section may be greater than a respective one or more of the subpixel aperture ratios of the second section to overcome image color variance that may exist due to temperature variations of the display.Type: GrantFiled: September 4, 2012Date of Patent: April 11, 2017Assignee: APPLE INC.Inventor: Chia-Ching Chu

Patent number: 9348692Abstract: A memory controller includes a damaged-column manager, an error checking and correcting decoder (ECC decoder) and a damaged-column decision circuit. The damaged-column manager logs a damaged-column address information in the flash memory. The ECC decoder receives a read data read by the flash memory and generates an error information according to whether or not the read data has error. The damaged-column decision circuit receives the error-column address and counts the number of accumulated generated times corresponding to the error-column address. The damaged-column decision circuit updates the damaged-column address information according to an error information.Type: GrantFiled: October 16, 2013Date of Patent: May 24, 2016Assignee: Asolid Technology Co., Ltd.Inventor: Chia-Ching Chu

Publication number: 20150363450Abstract: A counting engine for a Bayesian sequential partition system in a D-dimensional data space is provided. The counting engine includes a filtering module and a counting module. The filtering module is used for comparing at least one under-test data point with D boundary information corresponding to a sub-region, and consequently generating D flag sets. The counting module is connected with the filtering module. The counting module determines whether the at least one under-test data point lies in the sub-region, and consequently generates a result signal. A counting value corresponding to the sub-region is selectively accumulated by the counting module according to the result signal.Type: ApplicationFiled: June 12, 2015Publication date: December 17, 2015Inventors: Chen-Yi Lee, Hsie-Chia Chang, Shu-Yu Hsu, Chih-Lung Chen, Chang-Hung Tsai, Wing-Hung Wong, Tung-Yu Wu, Ying-Siou Liao, Chia-Ching Chu, Fang-Ju Ku

Patent number: 9076376Abstract: Systems, methods, and devices for white point calibration using subtractive color measurements are provided. Specifically, a white point of a display may be calibrated using subtractive color measurements rather than merely additive color measurements. In one example, a display having red, green, and blue pixels may measure the responses in a subtractive color space (e.g., CMY) rather than additive color space (e.g., RGB). Measurements of the display response using subtractive color space may involve providing image data to two or more color channels at once. Thus, any crosstalk effect between channels may be accounted for, even though the same crosstalk effect might not be apparent using additive color measurements in which only a single channel color channel were measured.Type: GrantFiled: April 11, 2013Date of Patent: July 7, 2015Assignee: APPLE INC.Inventors: Chia-Ching Chu, Gabriel G. Marcu, Jiaying Wu

Patent number: 9069692Abstract: A memory system, a fully parallel encoding method, and a fully parallel decoding method are disclosed. The encoding method utilizes a plurality of minimal polynomials that constitute a generator polynomial to derive a plurality of roots from the minimal polynomials. A first encoding matrix derived according to the roots of the minimal polynomials is subsequently decomposed to derive a second encoding matrix, in which partial elements of the second encoding matrix are common in those of a parity check matrix of the decoder, such that the encoder and the decoder can efficiently share the same hardware. In addition, the decoding method defines a new error locator polynomial and utilizes a cubic matrix operation to respectively combine the equations, which reduces the hardware required by the fully parallel architecture.Type: GrantFiled: March 29, 2013Date of Patent: June 30, 2015Assignee: NATIONAL CHIAO TUNG UNIVERSITYInventors: Chia-Ching Chu, Yi-Min Lin, Chi-Heng Yang, Hsie-Chia Chang
