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.

Description

technical field [0001] The present invention relates to a video display device having an external device association unit for controlling the operation of an external device by the video display device or for controlling the operation of the video display device by an external device. Background technique [0002] In recent years, with the popularization of video disc players and the like, there has been an increasing demand for large-screen video display devices that display powerful video on a large screen. As a large-screen video display device, for example, a projector device that is a projection-type video display device is known. By combining a projector device with a screen, it is possible to display large-screen images. When a projector device and a screen are used in combination, in order to prevent damage to the screen surface, the screen is generally stored when not viewing images, and taken out and unfolded when in use. Since the screen is stored again after us...
