摘要： Disclosed are touch screen devices and methods of sensing an object near the surface of a touch screen device. A capacitive sensor is integrated into display electronics by flipping the traditional thin film transistor liquid crystal display (TFT) stack-up which has a bottom gate structure so that it is an inverted bottom gate structure. Accordingly, the gate structure is near the top of the display and the gate drive lines are re-used as excitation lines in addition to their function as display lines. The excitation lines therefore drive excitation to generate an induced electric field at the surface of the display device. Additionally, other lines are used as sensor lines so that sensor signals are input to the device controller to determine the position of an object at the surface of the display device. Accordingly, the excitation lines are scanned to detect the presence of a finger or other object.

摘要： In accordance with one embodiment, apparatus are provided, which include a burn-in compensation pixel generator and burn-in compensation circuitry. The burn-in compensation pixel generator is configured to generate burn-in compensation pixel data. The burn-in compensation circuitry is configured to provide, within break-from-standard-use periods of a device employing a display, the generated burn-in compensation pixel data instead of a select predetermined subset of default pixel data, for input to a display interface of the display.

摘要： 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).
