US Classification:

345690, 345692, 348771

Abstract:

Disclosed herein are visual display systems and methods capable of having shifted bit-weights in neutral density filtering (NDF) applications. In one embodiment, a method () of displaying an image comprises transmitting light through an optical filter () comprising at least one high transmissivity portion configured to output light at an initial intensity, and at least one low transmissivity portion configured to output light at a lower intensity than the initial intensity, where the initial intensity and lower intensity output light illuminates a spatial light modulator (). The method also includes providing a plurality of data bits (non-ND) from a predetermined number of data bits (B–B), where each of the plurality comprises a pulse-width longer than a load-time for operating the spatial light modulator (). In this embodiment, the method further includes providing at least one data bit (ND) from the predetermined number of data bits, where the at least one data bit comprises an initial pulse-width less than the load-time and comprises an adjusted pulse-width greater than the load-time. Then, the method further comprises operating selected portions of the spatial light modulator () in coordination with the initial intensity and lower intensity output light using the pulse-widths of one or more of the plurality of data bits (non-ND) and the adjusted pulse-width of the at least one data bit (ND).

Abstract:

In accordance with one embodiment, a method for emulating the color performance of a display system includes determining an expected first color gamut of the display system. Display data is converted into a format that emulates the first color gamut. The converted display data is displayed by a different display system having an expected second color gamut different than the expected first color gamut.

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.

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.

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.
