International Classification:
H05B 37/02
G09G 5/00
US Classification:
315299, 315308, 315312, 315360, 345204
Abstract:
Power management in a light emitting diode (LED) system having a plurality of LED strings is disclosed. A voltage source provides an output voltage to drive a plurality of LED strings. An LED driver implements a feedback mechanism to monitor the tail voltages of the active LED strings to identify the minimum tail voltage and adjust the output voltage of the voltage source based on the lowest tail voltage. A loop calibration module of the LED driver calibrates the feedback mechanism of the LED driver based on a relationship between a digital code value used to generate a particular output voltage and another digital code value generated based on the minimum tail voltage resulting from the particular output voltage.

Bin Zhao - Irvine CA,
Jack W. Cornish - Foothill Ranch CA,
Brian B. Horng - Irvine CA,
Andrew M. Kameya - Irvine CA,
Kenneth C. Kwok - Irvine CA,
Victor K. Lee - Irvine CA,
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H05B 37/02
US Classification:
315299, 315185 S, 315308, 315312, 315360
Abstract:
A light emitting diode (LED) system implements a LED driver to drive a set of one or more LED strings. The LED driver includes a voltage source to provide an adjustable output voltage to a head end of each LED string of the set for a first duration and a second duration following the first duration. The LED driver further includes a feedback controller to control the voltage source to adjust the output voltage for the second duration based on a digital code value generated from a minimum tail voltage of one or more tail voltages of the set at a sample point of the first duration. The LED driver further includes a power controller to temporarily enable one or more components of the feedback controller for a sample period of the first duration, the sample period comprising the sample point.

Led Driver With Frame-Based Dynamic Power Management

US Patent:
8279144, Oct 2, 2012
Filed:
Jul 31, 2008
Appl. No.:
12/183492
Inventors:
Bin Zhao - Irvine CA,
Jack W. Cornish - Foothill Ranch CA,
Brian B. Horng - Irvine CA,
Andrew M Kameya - Irvine CA,
Jan Krellner - Chandler AZ,
Kenneth C. Kwok - Irvine CA,
Victor K. Lee - Irvine CA,
Weizhuang W. Xin - Aliso Viejo CA,
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
G09G 3/32
US Classification:
345 82, 315297
Abstract:
Disclosed are example techniques for frame-based power management in a light emitting diode (LED) system having a plurality of LED strings. A voltage source provides an output voltage to drive the LED strings. An LED driver generates a frame timing reference representative of the frame rate or display timing of a series of image frames to be displayed via the LED system. An update reference is generated from the frame timing reference. The LED driver monitors one or more operating parameters of the LED system. In response to update triggers marked by the update reference, the LED driver adjusts the output voltage of the voltage source based on the status of each of the one or more monitored operating parameters (either from the previous update period or determined in response to the update trigger), thereby synchronizing the updating of the output voltage to the frame rate (or a virtual approximation of the frame rate) of the video being displayed.

Method And Apparatus For Illuminating An Object Bearing Indicia

US Patent:
3944979, Mar 16, 1976
Filed:
Dec 23, 1974
Appl. No.:
5/535767
Inventors:
Kenneth Kwok - Inglewood CA
Assignee:
Data Source Corporation - Wilmington DE
International Classification:
G06K 714
US Classification:
3401463AG
Abstract:
A light source in an optical character recognition system is automatically controlled to operate at a plurality of light intensities. A relatively high light intensity is used to illuminate an object bearing indicia to be read. A relatively low light intensity is used at all other times. A plurality of detectors sense reflected or ambient light and produce output signals indicative of the intensity of the reflected or ambient light. First and second signals are generated to indicate whether the detector output is greater than or less than a predetermined threshold. The number of first and second signals generated in response to the outputs of the detectors are summed separately. If the number of first signals equals or exceeds a first predetermined number, the object is illuminated at a high light intensity. If the number of first signals is less than the first predetermined number, or if the number of second signals generated equals or exceeds a second predetermined number, the light source is switched to a low level light intensity.
