Abstract:
An electronic device includes a case having an opening, an electronic circuit and a dust cover. The electronic circuit is disposed in the case and includes a circuit board, a switch, and an expansion card slot. The switch and the expansion card slot are electrically connected at the circuit board. The opening exposes the switch and the expansion card slot. The expansion card slot includes an electrical connector used for electrical connection with an expansion card. The dust cover is detachably disposed at the opening. The dust cover includes a cap portion, a press portion and an elastic portion. The cap portion closes the opening. The press portion faces the switch. The elastic portion is respectively connected to the cap portion and the press portion, so the press portion is capable of moving relative to the cap portion and hence has a trigger position and a release position.

Abstract:
A control device for an image display includes at least two reference points, a modulation unit and a remote controller. The modulation unit modulates the light of a predetermined spectrum generated by the reference points with a brightness variation cycle. The modulation unit controls the reference points to emit the light with a first brightness within a first period of the brightness variation cycle and to emit the light with a second brightness within a second period of the brightness variation cycle, wherein the first brightness and the second brightness are not zero gray level. The remote controller captures the light of the predetermined spectrum with a sampling cycle and demodulates an image variation of the reference points with respect to the remote controller. The present invention further provides a control method for an image display.
