20080204431 | DISPLAY SYSTEM - A display system is provided including forming a display array, connecting a control block to the display array, configuring a communication protocol between the display array and the control block, and operating the display array with the communication protocol. | 08-28-2008 |
20090204860 | Data signal handling circuitry and methods with error analysis capabilities - To help identify a noise (interference) source in an electronic device that may be causing data errors in the device, relatively low level data receiver circuitry in the device is provided with one or more error signal output leads. An error signal on such a lead includes an error indication as soon as possible after the associated low level circuitry detects a data error. The timing of such an error indication is compared to the timing of noise from various possible noise sources in the device. The noise source that produced significant noise closest in time prior to the error indication may be identified as the noise source that was probably responsible for the data error that caused the error indication. | 08-13-2009 |
20090244878 | Conforming, electro-magnetic interference reducing cover for circuit components - An electronic circuit component is provided with shielding for electro-magnetic interference (“EMI”) by covering at least part of the component with a layer of electrical insulation that conforms to the shape of the surface to which the insulation is applied. At least part of the surface of the insulation is then covered by a layer of EMI shielding that conforms to the shape of the surface of the insulation to which the shielding is applied. | 10-01-2009 |
20100043222 | CONFORMING, ELECTRO-MAGNETIC INTERFERENCE REDUCING COVER FOR CIRCUIT COMPONENTS - An electronic circuit component is provided with shielding for electromagnetic interference (“EMI”) by covering at least part of the component with a layer of electrical insulation that conforms to the shape of the surface to which the insulation is applied. At least part of the surface of the insulation is then covered by a layer of EMI shielding that conforms to the shape of the surface of the insulation to which the shielding is applied. | 02-25-2010 |
20100073859 | P-Chassis Arrangement for Positioning a Display Stack - Methods and apparatus for aligning a display stack with respect to a housing associated with a portable electronic device are disclosed. According to one aspect of the present invention, a chassis arrangement suitable for use in aligning a display stack with respect to a housing includes a first portion, a second portion, and a coupling arrangement. The first portion is configured to engage the display stack, and the second portion is configured to enable the display stack to be manipulated when the display stack is engaged by the first portion. The coupling arrangement couples the first portion with the second portion, and is configured to enable the second portion to be detached from the first portion. | 03-25-2010 |
20100117549 | PULSE-WIDTH MODULATION CONTROL FOR BACKLIGHTING OF A VIDEO DISPLAY - A pulse-width modulated backlight control for a video display restarts the pulse-width modulated pulse train on occurrence of a video refresh pulse. In order to prevent an undesirable momentary increase in brightness in the event that the last pulse of the pre-refresh pulse train occurs too close to the first pulse of the post-refresh pulse train relative to the normal pulse interval, the width of the first pulse following refresh may be reduced from a first value determined by the desired brightness to a second value that bears the same proportion to the first value that the interval between the beginning of the previous pulse and the occurrence of the refresh pulse bore to the normal pulse interval. In that way, the duty cycle during the shortened pulse interval is the same as during a normal pulse interval, avoiding or minimizing perceptible increase in backlight brightness. | 05-13-2010 |
20110032285 | BACKLIGHT CONTROL OF ELECTRONIC DEVICE - Embodiments are provided herein which may be utilized to eliminate stray light emissions from an LED while ambient light is being sensed. As such, dynamic backlight control systems for use with an electronic display are presented including: an ambient light sensor for sensing ambient light intensity; a backlight for illuminating the electronic display; a switch for controlling the backlight, the switch configured to set a backlight condition to ON or OFF in response to a backlight-off frequency such that the ambient light sensor senses the ambient light intensity in the absence of the backlight; a logic module for determining a backlight level in response to the ambient light intensity; and a backlight control circuit for adjusting the backlight to the backlight level in response to the ambient light intensity. | 02-10-2011 |
20110110054 | COMPACT DISPLAY FLEX AND DRIVER SUB-ASSEMBLIES - Compact sub-assemblies of flexible circuits and drivers are provided. The sub-assemblies can occupy less space in an electronic device than conventional sub-assemblies. In one or more embodiments of the present invention, the flexible circuits can be attached to or wires can be disposed on portions of the substrate that previously were unoccupied in conventional sub-assemblies. In one or more embodiments, the sub-assemblies of the present invention also can have wires disposed underneath the driver or vary the width of the wires. In one or more embodiments, the sub-assemblies of the present invention also can have composite wires that occupy less space than wires of conventional sub-assemblies, while still maintaining similar energy flux. | 05-12-2011 |
20110169878 | DISPLAY SYSTEM - A display system is provided including forming a display array, connecting a control block to the display array, configuring a communication protocol between the display array and the control block, and operating the display array with the communication protocol. | 07-14-2011 |
