Patent number: 7990353Abstract: A method is provided for compensating for output nonuniformity on a display. The method comprises characterizing the display. The method further includes creating a set of data tables wherein one table provides data for compensation along vertical axes of the display and a second table provided data for compensation along horizontal axes of the display, and wherein components of the tables include a linear offset factor to correct data for nonuniformity and a slope factor which permits gray scale information to be recovered at points near the limits of the gray scale range. The characterizing step may include using a optical detector to obtain optical output information from the display. The slope factor may be calculated to preserve top end gray scale range of the display by adjusting luminous output so that input data level maps to separate output grey levels between a truncated and an untruncated level.Type: GrantFiled: September 18, 2006Date of Patent: August 2, 2011Assignee: Jasper Display Corp.Inventor: Wing Hong Chow

Patent number: 6151011Abstract: A system and method for reducing the phase difference between adjacent gray scale values employ compound data words. The compound data words include a first group of data bits and a second group of data bits. A display driver circuit is configured to provide display control signals causing each bit of the first group of data bits to be asserted on the display pixel for a coequal time period, and causing each bit of the second group of data bits to be asserted on the display pixel for a time period dependent on an associated significance of each bit. Optionally, the display driver circuit further includes a compound data generator configured to provide the compound data words. A method for asserting a compound data word on a display pixel includes the steps of asserting each bit of the first group of bits on the display pixel for a coequal time period, and asserting each bit of the second group of bits on the display pixel for a time period dependent on an associated significance of each bit.Type: GrantFiled: February 27, 1998Date of Patent: November 21, 2000Assignee: Aurora Systems, Inc.Inventors: W.

Patent number: 5815043Abstract: An improved ring oscillator in which frequency drift is controlled to provide reasonable accuracy is disclosed. The improved ring oscillator eliminates the frequency drift due processing variances. The ring oscillator provided by the invention incurs substantially less frequency drift than a conventional ring oscillator, but the frequency of the ring oscillator is still dependent on temperature and voltage changes. The improved ring oscillator according to the invention is particularly suited for operating as a localized oscillator that is used to facilitate periodic refreshing of DRAM within a computer.Type: GrantFiled: February 13, 1997Date of Patent: September 29, 1998Assignee: Apple Computer, Inc.Inventors: Wing Hong Chow, Robert L.

Patent number: 5623677Abstract: A method and apparatus for reducing the power consumption of a processor in a computer system where a programming structure running on the processor determines when the processor is in an inactive state to cause clocking signals and the power supply to be disabled to the processor. The processor is again coupled to the power supply and the clock signals in response to a periodic interrupt signal, a non-periodic interrupt or a bus request from a peripheral device. Thereafter, the programming structure signals the control logic again when the processor reenters the inactive state, such that the control logic disables the clock signals and decouples the power supply to the processor when the processor returns to the inactive state. The method is extended to offer the ability to shut down the processor from programming structures running on alternate masters or subsystem controllers within the same system.Type: GrantFiled: February 29, 1996Date of Patent: April 22, 1997Assignee: Apple Computer, Inc.Inventors: David B. Townsley, Wing-Hong Chow, Michael D. Johnson, Helder Ramalho
