Title: Active matrix type panel
Inventor: MATSUEDA YOJIRO
IPC: H04N5/74
Filed: 1990-04-06
Abstract: PURPOSE:To obtain a driver incorporated type panel which is changeable in shift direction at need and can be prevented from decreasing in operation speed by providing drivers for signal lines which differ in shift direction. CONSTITUTION:An X driver 11 dedicated to right shifting and an X driver 12 dedicated to left shifting are provided independently and both supplied with electric power from a power source VDD terminal and a VSS terminal, and although common clock pulses CLX are inputted to the both, start pulses are different between the drivers. Namely, when the start pulse DXR is inputted to the X driver 11, a rightward shift is made in order according to the period of the shift clock CLX and the X driver 12 holds its start pulse DXL terminal at the same potential as a negative power source VSS to turn off all sample -and- hold TFTs 2. When the shift direction is changed, the signal line driver to be operated is switched to easily change the shift direction. Consequently, the direction of an image can be inverted at any time and there is no mutual interference, so there is no delay in operation speed.
