摘要： A television receiver monitor intended to be built into a wall and used in connection with an audio/video entertainment center can be adapted to provide various visual aspects corresponding to the control capabilities of the user. When only a bezel surrounding the screen is visible, all controls are made through a control center unit of the audio/video entertainment center, so that the user must have a high degree of knowledge about the overall system, whereas when the bezel and a control panel are visible, the user need not extensively involve himself with the audio/video entertainment center except to control the audio portion of the program. When confronted with an unsophisticated or underage user, a speaker grill is provided in addition to the bezel and control panel, so that no interaction with the audio/video entertainment center is required by the user in order to enjoy a video and audio program.

摘要： An apparatus for checking the alignment of a projection lens assembly includes a base for mounting the apparatus on the projection lens assembly, a gimbal system having a bottom section mounted to the base and a top section, the gimbal system having position adjusters for adjusting the position of the bottom section in two orthogonal direction with respect to the base, and having tilt adjusters for angularly adjusting a plane of the top section with a plane of the base, and a laser generator mounted on the top section. The position adjusters and the tilt adjusters are used to position a laser beam to be emitted by the laser generation to be coaxial with a central axis of the projection lens assembly. When the laser generator is then energized, the laser beam forms a visible red dot on the rear projection screen and, using simple measurements, an operator is able to verify the alignment of the projection lens assembly in the rear projection television receiver.

摘要： A television system performs beam convergence in video displays. The system is implemented through one or more convergence sensors, which are exposed to two distinct convergence test patterns. The output signals from the sensors when exposed to the two test patterns are used in beam convergence calculations. The test patterns are selected to reduce the dynamic range requirement for an A/D converter in the television system supplied with the sensor output signals. A low-pass filter circuit with selectable characteristics is also used to reduce the dynamic range requirement.

摘要： A projection display system may be mechanically perturbed to remove or reduce speckle. In addition, pixellation effects may also be removed or reduced. By mechanically disturbing a portion of the system, for example using a wobble perturbation, the speckle effects may be temporally smeared so that they become invisible to the user. In one embodiment of the present invention, a folding mirror may be mechanically perturbed, using a plurality of piezoelectric actuators, at frequencies in the ultrasonic range.

摘要： An image display device, having a casing in which a television device and a video device are enclosed, includes a main circuit board having a first area for installing electronic parts of a power supply circuit and a second area for installing remaining electronic parts for TV and video device. Since the electronic parts of the power supply circuit are arranged within a separated area formed on the main circuit board, the electronic parts for the TV device and the electronic parts for the video device can be installed with high density and with no substantial interference with each other.
