Abstract: A touchscreen display system (418) is provided which includes a touchscreen (420), a touchscreen input detector (422), a capacitive sensor driver (423), and a display driver (424). The touchscreen input detector (422) is coupled to a first layer (504) of the touchscreen (420) and determines a touchscreen (420) input in response to sensing tactile inputs during a sensing time interval (610). The display driver (424) is coupled to a second layer (506) of the touchscreen (420) and provides a drive voltage (606, 608) at a first voltage level to the plurality of optical shutter segments (508) during a first portion (620) of the sensing time interval (610) and maintains the drive voltage (606, 608) at substantially zero volts during a second portion (622) of the sensing time interval (610), the second portion (622) being greater than half of the sensing time interval (610).

Abstract: An embodiment generally relates to a method of communicating with a plurality of registers in a display driver integrated circuit (IC). The method includes providing a data message and driving the data message over color select lines of the display driver IC in response to the display driver IC being in an overscan condition.

Abstract: A display device including a plurality of display elements (500) arranged in a matrix, wherein each display element includes a display pixel (510) coupled to a switch (530), and each display element includes an addressable latch (540) having an output coupled to a controlling input of the switch. The addressable latch includes a row address input (532) and a column address input (556). In one mode of operation, at least some display elements are activated at a first rate, and other display elements are activated at a second rate less than the first refresh rate by selectively addressing the display elements.
