Abstract
The present invention provides a display driving circuit and a display driving method for driving a first panel and a second panel, and provides a multi-panel display using the same. The display driving circuit comprises a data driver for driving a plurality of data lines of the second panel; and a voltage switch circuit, coupling to the data lines for determining whether to conduct a predetermined voltage to the data lines according to ON/OFF status of the first and second panels.
Claims15
A display driving circuit for driving a first panel and a second panel, comprising:
- a data driver for driving a plurality of data lines of the second panel;
- and
- a voltage switch circuit, coupling to the data lines for determining whether to conduct a predetermined voltage to the data lines according to ON/OFF status of the first and second panels.
A display driving method for multi-panel display, comprising:
- sending data signals to a plurality of data lines of one of a plurality of panels in the multi-panel display;
- and
- providing a predetermined voltage to the data lines when said one of the panels is turned off and at least another one of the panels is turned on.
A multi-panel display, comprising:
- a controller providing a plurality of data signals;
- a first panel comprising a plurality of first data lines coupling to the controller for receiving the data signals;
- a second panel comprising a plurality of second data lines coupling to the controller for receiving the data signals;
- and
- a voltage switch circuit, coupling to the second data lines for providing a predetermined voltage to the second data lines according to a switch control signal.
An electronic device, comprising:
- a multi-panel display as claim in 9;
- and
- an input module for providing image data to the display device.
