摘要：
A drive circuit for a flat display apparatus is disclosed wherein different display objects can be displayed at a time individually with appropriate gamma characteristics. Reference voltages are produced in a plurality of systems having different gamma characteristics from each other, and one of the systems is selected in response to a selection signal. Then, the reference voltages of the selected system are selected in response to image data to set gradations of pixels.
