Abstract
A driving circuit for a double display panel is disclosed. The driving circuit drives a first display panel and a second display panel, and includes an ASIC and two pairs of driving ports. The ASIC outputs a driving signal pair including two signals which are opposite in phase to each other. A first pair of driving ports electrically connected to the first display panel and the ASIC, receiving the driving signal pair to determine whether to activate the first display panel or not. A second pair of driving ports electrically connected to the second display panel and the ASIC, receiving the driving signal pair to determine whether to activate the second display panel or not. The driving signal pair determining the activation of the first and second display panel is the same for both panels, and only one of the display panels can be activated at a time.
