摘要： A display module (100) with reduced power consumption uses a control circuit (110) to reset row and column display drivers (130, 140) and turn off a portion of the display (150) when the display module (100) is in a partial display mode. The partial display mode allows a reduction in the driving voltages for the display which in turn reduces the power needed by the bias voltage divider (120) which produces the driving voltages. The display module (100) with reduced power consumption is applicable to both LCD and non-LCD technologies, such as electroluminescence or cathode ray tube, using a multiplex or scanning methodology.

摘要： A method and apparatus for controlling a plurality of light sources (102,103,104,105) in an electronic device (100) is provided. In one embodiment, the plurality of light sources (102,103,104,105) is used to backlight an illuminated display (101). As switching multiple light sources on simultaneously can cause output voltages of power sources (219) to drop, thereby potentially affecting the overall operation of the electronic device (100), an illumination controller (107) distributes actuation times associated with illumination control signals (204,205,206,207) such that each actuation time is unique. A control signal generator (201) produces a control signal (202) having light source actuation information stored therein. The illumination controller (107) then generates a plurality of illumination control signals (204,205,206,207) that are capable of actuating the plurality of light sources (102,103,104,105). Each illumination control signal (204,205,206,207) has a duty cycle and actuation time associated therewith. The illumination controller (107) distributes the actuation times across the control signal (202) so as to reduce the instantaneous current drawn by the plurality of light sources (102,103,104,105).
摘要翻译：提供一种用于控制电子设备（100）中的多个光源（102,103,104,105）的方法和装置。在一个实施例中，多个光源（102,103,104,105）用于背光照明显示器（101）。由于同时切换多个光源可能导致电源（219）的输出电压下降，从而潜在地影响电子设备（100）的总体操作，照明控制器（107）分配与照明控制信号相关联的致动时间（204,205,206,207 ），使得每个启动时间是唯一的。控制信号发生器（201）产生其中存储有光源致动信息的控制信号（202）。照明控制器（107）然后产生能够致动多个光源（102,103,104,105）的多个照明控制信号（204,205,206,207）。每个照明控制信号（204,205,206,207）具有与之相关联的占空比和启动时间。照明控制器（107）跨越控制信号（202）分配致动时间，以便减少由多个光源（102,103,104,105）吸取的瞬时电流。
