Patent number: 9589514Abstract: Methods and apparatus for reduced bandwidth pulse width modulation are disclosed. A system includes a digital controller circuit coupled to a data interface, the digital controller circuit configured to receive image data for display and further configured to encode line data for transmission to a spatial light modulator using a data compression scheme; and the spatial light modulator coupled to the data interface and configured to receive encoded data and to decode the encoded data to produce unencoded data corresponding to pixel data for display on an array of pixel elements in the spatial light modulator; wherein data transmitted from the digital controller circuit to the spatial light modulator further comprises encoded data that is formed from bit planes using a data compression scheme to form partial lines of data. Additional methods and apparatus are disclosed.Type: GrantFiled: February 19, 2015Date of Patent: March 7, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Todd Alan Clatanoff, Jeffrey Matthew Kempf

Patent number: 9230296Abstract: A method of controlling micromirrors of reset groups of a spatial light modulator (SLM) digital micromirror array is disclosed. In a first reset operation, the positions of a first subgroup of micromirrors of a reset group are set based on a first portion of a first bitplane and the positions of a second subgroup of micromirrors of the same reset group are set based on a first portion of a second bitplane. Then, in a second reset operation, the positions of the first subgroup are set based on a second portion of the second bitplane and the positions of the second subgroup are set based on a second portion of a first bitplane. In one example, subsets of alternating rows of micromirrors of the same reset group are successively set according to alternating data corresponding to different ones of first and second bitplanes.Type: GrantFiled: February 28, 2013Date of Patent: January 5, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Todd Alan Clatanoff, Philip Scott King, Jeffrey Mathew Kempf

Patent number: 8558771Abstract: System and method for dynamically altering a color gamut used in projection display systems. An embodiment comprises determining a dim color from colors used in representing an image, adjusting the dim color to increase an available display time for a non-dim color used to represent the image, adjusting the non-dim color using the available display time, and generating a color sequence based on the adjusted dim color and the adjusted non-dim color. The pixel intensities of a dim color are increased, permitting a shortening of the display time of the dim color. The newly freed display time can be reallocated to all colors to increase the amount of light used to display the image, thereby increasing image brightness or altering color point.Type: GrantFiled: June 29, 2011Date of Patent: October 15, 2013Assignee: Texas Instruments IncorporatedInventors: Todd Alan Clatanoff, Gregory S. Pettitt

Patent number: 8149252Abstract: A display uses x illuminator systems to produce x primary colors and y overlap colors, which are combinations of primary colors, to illuminate a spatial light modulator in a display system. A first set of n duty cycles for the x primary colors over a frame is provided, wherein the display system can select any one of the duty cycles to produce a desired white point. A second set of n duty cycles of x+y colors over a frame corresponding to the first set of duty cycles is determined, where the second set of duty cycles are generated responsive to a specified desired allocation of the frame to the y overlap colors, such that each of the overlap colors can be displayed from a dark shade to a bright shade while maintaining a constant color point.Type: GrantFiled: May 22, 2008Date of Patent: April 3, 2012Assignee: Texas Instruments IncorporatedInventor: Todd Alan Clatanoff
