Abstract
A method includes receiving first touch point data from a sensor, generating first data pixels corresponding with the received first touch point data, and updating first display pixels of a display device with the first data pixels using a first drive scheme. The display pixels of the display device may have multiple stable display states and the first data pixels may be generated by a first unit. The method may further include receiving second touch point data from the sensor, generating second data pixels corresponding with the received second touch point data, and updating second display pixels of the display device with the second data pixels using a second drive scheme. The first and second drive schemes may be different drive schemes. The second data pixels may be generated by the first unit.
