Abstract: A voltage supplied from a power supply is boosted by a boosting circuit unit to generate a direct-current voltage, and the pulse-shape direct-current voltage is applied to LED while a constant-voltage control unit controls the direct-current voltage. The operation of LED is controlled by a control unit and a PWM unit. When the current is passed through LED, the constant-voltage control unit obtains information on the current passed through LED from a potential difference between both ends of a resistor, and on-and-off control of the voltage applied to LED from the boosting circuit unit is performed at a high frequency based on the information. Therefore, the voltage applied to LED can be controlled to keep the current passed through LED constant.

Abstract: A safe, highly bright projector is to be implemented. A projector directs a light beam from a light source (101) to an image modulating device (105), and magnifies and projects an image formed at the image modulating device (105) through a zoom lens (102). This projector has a light transmitting window (103) movably disposed in front of the surface of the light outgoing side of the zoom lens (102) along the optical axis. The projector further has a window position control unit (108) to control the position of the light transmitting window (103) so as not to change the light beam region that appears on the outer surface of the light transmitting window (103) as the focal length of the zoom lens (102) is varied.

Abstract: In the case when password data (PW1) added to a TV broadcasting signal and password data (PW2) transmitted from an Internet connection section (2) have a predetermined correlation with each other, the display section (3) is allowed to display the corresponding contents normally. Therefore, accounting processes are imposed on the transmission of the password data (PW2) so that a normal displaying operation is charged in an indirect manner for each of the contents.

Abstract: A stand for a thin display includes a vertical position adjustment mechanism; and a switchover mechanism for switching over between a vertical orientation and a horizontal orientation of a thin display. When the switchover mechanism has rotated the thin display, the vertical position adjustment mechanism has different movement ranges between the vertical orientation and the horizontal orientation. Accordingly, when the thin display is in a vertical orientation, the lower end of the thin display does not hit against a base, which provides a easy and reliable operation even in a vertical orientation or in a horizontal orientation.
