Abstract
A display apparatus includes a first circuit board where a timing controller is disposed, a connector connected to the first circuit board, a second circuit board connected to the first circuit board, based on the connector, a controller disposed on the first circuit board to output a control signal, and a parasitic resonance control circuit configured to vary a parasitic value of the connector, based on the control signal output from the controller.
Claims9
A display apparatus comprising:
- a first circuit board configured to output a timing control signal;
- a connector connected to the first circuit board;
- a second circuit board connected to the first circuit board, through the connector;
- a controller disposed on the first circuit board and configured to output a control signal;
- a pad part on which the connector is attached in the first circuit board;
- and a parasitic resonance control circuit configured to vary a parasitic value of the connector, based on the control signal output from the controller, the parasitic resonance control circuit including a second circuit unit deposited at two ends of the pad part, the circuit unit configured to vary a parasitic resonance magnitude of the connector, a low voltage electrode part and a ground pad part disposed at a periphery of the connector, wherein the controller is configured to senses a voltage from at least one of the low voltage electrode part or the ground pad part to obtain a sensing value, wherein the ground pad part includes an island shape and is isolated from a ground electrode disposed in the first circuit board.
