20090128786, May 21, 2009

Filed:

Nov 19, 2007

Appl. No.:

11/942237

Inventors:

David Foster Lieb - Dallas TX, US
Jason Ryan Thompson - Dallas TX, US
Terry Alan Bartlett - Dallas TX, US
Steven Monroe Penn - Plano TX, US
Andrew Ian Russell - Plano TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G09G 3/36
G03B 21/28
G03B 21/14

US Classification:

353121, 345 87, 353 99

Abstract:

An imaging system comprises a light valve having an array of light valve pixels. For processing grayscale/color images, each light valve pixel represents a discrete grayscale level. During image processing, desired grayscales can be accomplished by imaging the light valve pixels onto the target such that the perceived grayscale of each target pixel is a sum of grayscales represented by a plurality of light valve pixels.

Appl. No.:

11/945925

Inventors:

Jason R. Thompson - Dallas TX, US

International Classification:

G01J 5/02

US Classification:

250348, 345207

Abstract:

A system for displaying images comprises a plurality of light sources, comprising at least one non-visible light source. The system further comprises a spatial light modulator operable to modulate non-visible light from the non-visible light source to encode one or more objects and for presentation on a display. Finally, the system comprises a detector operable to detect at least a portion of the non-visible light presented on the display.

Inventors:

- Dallas TX, US
Michael David McCormick - Allen TX, US
Jason Ryan Thompson - Dallas TX, US

International Classification:

H05B 33/08
H02J 7/00
G02B 27/01

Abstract:

For controlling a level of luminance produced by a color light-emitting diode (LED) array, a method includes: for a predetermined flux bit-slice period, activating a color enable signal to select a primary color LED and to select a predetermined light flux magnitude set-point; selectively charging an energy storage device and discharging the energy storage device through the selected primary color LED to generate a light flux output during the flux bit-slice period; adjusting a rate of selectively charging the energy storage device to maintain a magnitude of the light flux output at the predetermined light flux magnitude set-point during the flux bit-slice period; and adjusting the predetermined light flux magnitude set-point over the life of the selected LED as the selected LED ages as a function of an anode-to-cathode voltage drop across the selected LED for a given magnitude of current flowing through the selected LED.

International Classification:

H05B 33/08
G02B 27/01

US Classification:

359630, 315210, 307 66

Abstract:

Light flux levels sensed from a color LED array control both current availability to the array and disable/re-enable a current bypass switch to shunt stored-energy current to or away from a selected LED. In continuous mode, a single flux pulse is created for the duration of a pre-established period. Feedback from the flux sensor pulses current to an energy storage device to maintain the light flux at a predetermined set-point. A particular dimming level is achieved by establishing both the pulse period and the flux magnitude. In discontinuous mode, one or more short flux pulses are created. Both the turn-on and the turn-off time of each flux pulse is controlled by alternately removing and then re-establishing a current shunt from the energy storage device to ground. Flux pulse magnitude is controlled by recognizing when the flux pulse has reached a predetermined set-point and re-establishing the current shunt to abruptly turn off current to the selected LED.
