Image display apparatus with external-equipment-link unit

Abstract

An image display apparatus includes: an image display unit for forming and displaying an optical image; an external-equipment-link unit capable of sending/receiving a control signal to/from external equipment; and a control unit for controlling operations of the image display unit and the external-equipment-link unit. The external-equipment-link unit includes at least one control signal output circuit and at least one control signal input circuit, the control signal input circuit detects an input control signal inputted from the external equipment and supplies the input control signal to the control unit. The control unit controls the control signal output circuit to output an external equipment control signal to the external equipment in response to the image display apparatus being in a predetermined operation state, and the control unit controls operations of the image display apparatus based on the input control signal supplied from the control signal input circuit. Not only the operations of the external equipment can be controlled from the image display apparatus but also the operations of the image display apparatus can be controlled from the external equipment, which improves user convenience.
