摘要： Embodiments of the invention relate to a method and apparatus to drive non-resistive loads. The non-resistive load driver may include two or more drivers, such as a high-drive circuit and a low-drive circuit, to drive rail-to-rail output voltages and to stabilize the output voltages at a substantially constant level. The high-drive circuit may drive the output voltage of the non-resistive load driver to a threshold level, whereas the low-drive circuit may modify the output voltage of the non-resistive load driver to approximate an input voltage of the non-resistive load driver, and compensate any leakage associated with the non-resistive loads to provide a substantially constant output voltage. The low-drive circuit consumes less current than the high-drive circuit. The non-resistive load driver consumes less power and use less chip space. Alternatively, the non-resistive load driver may be implemented using a single driver with multiple modes, such as a low-drive mode and a high-drive mode, by changing a bias current of the non-resistive load driver between a high current mode and a low current mode.

摘要： Embodiments of the invention relate to a configurable LCD driver system having a plurality of configurable LCD drivers. Each LCD driver may be configured as a common or segment driver by selecting a drive voltage from an appropriate set of drive voltages associated with a common or segment driver in accordance with certain parameters, such as whether a user may configure the LCD driver as a common driver or segment driver, a multiplex ratio, and/or bias ratio of an LCD panel. The drive time and drive strength associated with the LCD driver may also be configurable. The selected drive voltage may be provided to a drive buffer to output an LCD drive voltage waveform for driving one or more segments or pixels in an LCD panel. A memory may store appropriate display data for both the segment and common drivers to control the output drive capability of the LCD driver.

摘要： Embodiments of the invention relate to a method and apparatus to reduce power consumption in a passive matrix LCD driver circuit by using a plurality of drive buffers and active power management of sub-blocks in the passive matrix LCD drive circuit. Each drive buffer may operate in a first phase, which may include a high-drive mode to drive an LCD voltage to a threshold voltage level and a low-drive mode to modify the LCD voltage to approximate an input voltage of the drive buffer, and to maintain a constant LCD voltage level. The low-drive buffer consumes less current than the high-drive buffer, thus reducing power consumption. The drive buffer may also operate in a second phase, also a no-drive mode, in which the drive buffer and the bias voltage generator may be completely turned off, to further reduce power consumption. The drive buffer may be used to drive capacitive loads, as well as partially-resistive loads and inductive loads.
