Patent number: 8379080Abstract: According to various illustrative embodiments, a device, system, and method for reducing stereoscopic phase-lag distortion under motion in a 3-dimensional video display are described. In one aspect, a method comprises reducing a phase difference between a first image and a second image in a portion of a frame time of the 3-dimensional video display. The method also comprises redistributing respective bit sequences of at least portions of the first image and the second image by respective amounts arranged to effect the reduction of the phase difference between the first image and the second image. The method also comprises displaying the redistributed respective bit sequences of the portions of the first image and the second image during the frame time of the 3-dimensional video display.Type: GrantFiled: July 6, 2007Date of Patent: February 19, 2013Assignee: Texas Instruments IncorporatedInventors: Andrew Ian Russell, Bradley William Walker

Patent number: 8379064Abstract: In display systems employing spatial light modulators, the OFF-state light from OFF-state pixels of the spatial light modulator can be captured and directed back to the pixels of the spatial light modulator so as to recycle the OFF-state light in the display system. Bitplanes derived from the desired image to be produced are calibrated to include the recycled off-state light to properly produce the desired image using the display system.Type: GrantFiled: April 18, 2011Date of Patent: February 19, 2013Assignee: Texas Instruments IncorporatedInventors: Andrew Ian Russell, David Foster Lieb, Rajeev Ramanath

Publication number: 20120320078Abstract: System and method for image-based color sequence reallocation in sequential color display systems. A method comprises generating a color signal from an image to be displayed, wherein the color signal contains light intensity information, computing percentages of the color sequence to be allocated to each color in a set of colors in a sequential color display system, wherein the computing is based on the light intensity information, allocating the color sequence based on the computed percentages, and displaying the image using the color sequence. The allocation of the color sequence based on the image allows for the elimination of color intensities that are greater than needed in displaying the image. Portions of the color sequence formerly used to display the eliminated color intensities may be used to display colors with usable intensities, thereby increasing the brightness of images.Type: ApplicationFiled: August 28, 2012Publication date: December 20, 2012Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Andrew Ian Russell, David Foster Lieb, Jeffrey Matthew Kempf

Patent number: 8305387Abstract: Adaptive pulse-width modulated sequences for sequential color display systems and methods. A method for displaying an image comprises receiving the image, computing a duty cycle for the image, generating a color sequence based on the computed duty cycle, and displaying the image using the color sequence. The generating comprises assigning a color cycle order to display time blocks in the color sequence, and assigning bitplane states for each display time block in the color sequence.Type: GrantFiled: September 7, 2007Date of Patent: November 6, 2012Assignee: Texas Instruments IncorporatedInventors: Andrew Ian Russell, David Foster Lieb, Jeffrey Matthew Kempf
