    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.

    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 display screen is capable of having regions having different switching speeds as well as regions that are not switched. One region having a first switching speed may be for colour mode display and the other region having a second switching speed different from the first may be for monochrome mode display. Other regions may be off and not switched. In alternative versions, three or more switched regions may be established on a display screen. For example, a monochrome region may be nested inside a colour region, in which the colour region may be nested between off regions.

    摘要: In a handheld computing device that includes a backlit display having a variable-intensity backlight, a method for controlling the intensity of light produced by the backlight involves the following steps. The computing device also includes user data input means, and data processing means coupled to the user data input means and the backlit display. The data processing means includes at least one software application that is configured to display information on the display. The method involves the steps of (1) setting the intensity to a first intensity level and activating one of the software applications; and (2) setting the intensity to a minimum intensity level, less than the first intensity level, after expiry of a predetermined elapsed time of non-activity from the user data input means. The predetermined elapsed time is based on the activated software application.
