摘要： A shielding material that can be arranged with respect to display elements to reduce potential damage or degraded performance caused by incident EM, such as UV and/or IR. The shielding material can be configured to be substantially transparent in visible light wavelengths. The shielding material can include inorganic materials, such as oxides including zinc oxide and titanium dioxide. Display elements can include a shielding material and an outer coating to reduce undesirable optical characteristics of an air/shielding material interface. The shielding material can be electrically conductive and function as a conductive layer in a microelectromechanical system (MEMS) device. In some embodiments, the shielding material can be disposed forward (closer to the viewer) of the electrodes of the display elements to prevent the high energy UV light from building up electrical charge in the electrodes. In some embodiments, the shielding material can also block certain wavelengths of light in the visible spectrum to darken the dark state of the display elements to improve the contrast ratio of the display.

摘要： A cathode ray tube (CRT) having a glass envelope is disclosed. The glass envelope is formed of a rectangular faceplate panel and a tubular neck connected thereto by a funnel. An electron gun is positioned in the neck for directing electron beams toward the faceplate panel. A yoke is positioned in the neighborhood of the funnel-to-neck junction. The yoke has windings configured to apply a horizontal deflection yoke field and a vertical deflection yoke field to the beams. At least one magnetic field sensor is located near the glass envelope for sensing an ambient magnetic field environment of the CRT. A controller receives a signal from the magnetic field sensor. Register correction coils are mounted in the vicinity of the neck and are dynamically controlled by the controller to shift the beams. Quadrupole coils are applied to the neck and have adjacent poles of alternating polarity such that the resultant magnetic field being dynamically controlled by the controller based on the magnetic field sensor signal moves outer ones of the beams to correct the misconvergence caused by the register correction.

摘要： A display includes a monitor module, a base and a shielding apparatus. The base is coupled to the monitor module, and the shielding apparatus is disposed between the base and the monitor module. The shielding apparatus includes a magnetic core and a non-flexible coiled device having a number of fixed shape coils. The coiled device is put through the magnetic core so that the magnetic core is selectively surrounded by at least one of the coils of the coiled device. The monitor module is therefore grounded via the shielding apparatus.

摘要： A dynamic degaussing system includes a magnetic field sensor for generating a sensor signal in response to a sensed magnetic field. The magnetic sensor is coupled to a controller that produces an output signal based on the sensor signal. The controller may include feedforward and feedback control loops. The output signal of the controller controls a magnetic field generator which generates a magnetic field so as to attenuate the sensed magnetic field. According to one aspect of the invention, a vessel is provided with a reduced magnetic signature and a control system for controlling magnetic fields about a podded electric motor. The control system employs feed-forward and feedback control in tandem. The control system may be dynamically adapted to changing physical characteristics of the motor. Control signals are generated in response to sensed or predicted magnetic fields internal to, or external to, the motor. The control inputs may be used to modify one or more motor driving currents, or to drive one or more magnetic field generators, so as to attenuate one or more magnetic field components generated by the motor.

摘要： A method of degaussing a cathode ray tube where two pairs of degaussing coils are arranged with one pair located at the top and bottom and the other to the right and left of the cathode ray tube after impaired color purity correction process of an electron beam has been carried out for the cathode ray tube using a magnetization process with a magnetization including an anticipated amount of degaussing for the cathode ray tube when the cathode ray tube is incorporated in a display device. The degaussing of a magnetic material within the cathode ray tube is then carried out with the anticipated amount of degaussing using the degaussing coils. In this way, a color cathode ray tub with no impaired color purity can be provided because the cathode ray trajectories corrected by magnetization in the magnetization process is not easily changed during use after incorporation in the display device.
