OPTICAL SHUTTERED TOUCHSCREEN AND METHOD THEREFOR |
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). |
