摘要:
A field sequential liquid crystal display maintains its white colour point through compensation values to at least one colour light emitting diode that illuminates the display. The compensation values may be impedances to control the current or pulsing of the current source according to a pulse width modulation technique. A degradation curve may be used to calculate extrapolate the theoretical forward voltage of the light emitting diode. Additional complexity arises from the need for calculating uptime for multiple light emitting diodes of different colours. Brightness levels may also be factored in.

摘要:
A method of manufacturing a portable computing device, involves the steps of (1) performing one manufacturing step in the manufacture of the portable computing device by interfacing a hardware component with another component of the computing device; and (2) performing a subsequent manufacturing step in the manufacture by (i) identifying the interfaced hardware component from a response received at the another component; and (ii) initializing the identified interfaced hardware component using a device driver associated therewith.

A method of manufacturing a portable computing device, involves the steps of (1) maintaining a table comprising stimulus/response data for possible hardware components that may be interfaced in the computing device; (2) performing one manufacturing step in the manufacture of the portable computing device by interfacing one of the possible hardware components with one other component of the computing device; and (3) performing one other manufacturing step in the manufacture by: (i) applying a stimulus to the interfaced hardware component, and reading a response from the interfaced hardware component in response to the applied stimulus; (ii) identifying the interfaced hardware component from a correlation of the response with the stimulus/response data; and (iii) saving the identification as configuration data in the computing device.

摘要:
A wireless handheld communications device with a liquid crystal display, especially, a field sequential liquid crystal display, includes a visual notification for a powered up, inactive state. The visual notification is preferably through a light emitting diode that may be part of the backlighting system for the LCD or may be independent from the backlighting system. The waveforms, periodicity, color selection, and color sequencing may be customizable by one or both of the manufacturer and user.
