Abstract

A display apparatus includes a display panel having a first connector, and a driving device having a second connector configured to electrically connect to the first connector, wherein the display panel includes a connection state confirmation unit configured to output a connection state signal including connection information between the first connector and the second connector, and wherein the driving device includes a first power supply configured to supply power to the display panel when the connection state signal includes the connection information that a connection state between the first connector and the second connector.

Claims12

Dependent claims

A display apparatus comprising:

a display panel comprising:
first pixels in a first display area;
second pixels in a second display area;
a first connector;
a connection state confirmation unit;
a gate driver configured to sequentially output scan signals to the first pixels and the second pixels;
a source driver configured to output data signals to the first pixels and the second pixels in synchronization with the scan signals;
and
a first power supply configured to supply power to the first pixels;
and
a driving device comprising:
a controller;
a second connector configured to electrically connect to the first connector;
and
a second power supply configured to supply power to the second pixels,
wherein the connection state confirmation unit is configured to output a connection state signal to the controller, wherein the connection state signal indicating the first connector and the second connector are correctly connected to each other,
wherein the controller is configured to receive the connection state signal and to enable the gate driver, the source driver, the first power supply and the second power supply in response to the connection state signal, and
wherein when the first and second power supplies are enabled under control of the controller, the first power supply supplies the power to the first pixels at the same time when the second power supply supplies the power to the second pixels.

A driving method of a display apparatus comprising a display panel and a driving device, wherein the display panel comprising first pixels in a first display area, second pixels in a second display area, a first connector, a connection state confirmation unit, a gate driver, a source driver and a first power supply and wherein the driving device comprising a controller, a second connector and a second power supply, the method comprising:

confirming, via the connection state confirmation unit, a connection state between the first connector and the second connector, in the display panel;
outputting a connection state signal from the connection state confirmation unit to the controller, wherein the connection state signal indicating the first connector and the second connector are correctly connected to each other;
receiving, via the controller, the connection state signal;
outputting, via the controller, control signals to the gate driver, the source driver, the first power supply and the second power supply in response to the connection state signal;
supplying, via the first power supply, power to the first pixels in response to the control signal from the controller;
supplying, via the second power supply, power to the second pixels in response to the control signal from the controller at the same time when the first pixels are powered by the first power supply;
sequentially outputting, via the gate driver, scan signals to the first pixels and the second pixels in response to the control signal from the controller when the first pixels are powered by the first power supply and the second pixels are powered by the second power supply;
and
outputting, via the source driver, data signals to the first pixels and the second pixels in synchronization with the scan signals in response to the control signal from the controller when the first pixels are powered by the first power supply and the second pixels are powered by the second power supply.
