Abstract: The liquid crystal display panel of the present invention provides rapid highlighting of the display. To provide highlighting, current to the backlighting lamp is increased from a normal current to a highlighting current. During the transition from the normal current to the highlighting current, the current to backlighting lamp is increased to an intermediate current above the highlighting current, and then decreased to the highlighting current. The increase to an intermediate current provides greater energy to the backlighting lamp than a direct increase from the low current to the highlighting current. The increased energy heats the backlighting lamp quickly to provide the increased light for highlighting. In addition, reducing the current to the backlighting lamp below the normal current when leaving the highlighting mode decreases the time to leave the highlighting mode.

Abstract: Backlighting is provided for an LCD-TV display by directing light from a source into an open end of a cylindrical drum, the other end of which is closed. The drum has a highly reflective inside surface and a beam is directed through an orifice in the cylindrical wall of the drum. A plurality of optical fibers are positioned with one end of each on a circle coaxial with the drum and the other end of each attached along one edge of the panel to which backlighting is provided. The drum, and thus the beam, is rotated about its axis at constant angular velocity, providing light sequentially to each of the fibers with resulting scrolling of the light across the panel behind the LCD array.

Abstract: An electronic ballast with a voltage-fed, LC or LLC resonant inverter for multiple gas discharge lamp independent operation which maintains a substantially constant voltage to a lamp or lamps connected to the ballast even during a transition period when a lamp or lamps is ignited, extinguished, added or removed. The ballast includes a feedback loop that maintains a substantially constant phase angle between the voltage and the current in an LC or LLC tank circuit, which has the effect of the ballast providing the substantially constant voltage output. The feedback loop obtains a current feedback signal and a voltage feedback signal from the tank circuit, and provides a phase shifted signal as a feedback correction signal which is the current feedback signal phase shifted by the voltage feedback signal that tracks phase angle changes with one, some or all of the lamps of a set thereof connected to the ballast, and during the transition period. The feedback loop includes a phase-shift circuit which includes at least one differential amplifier stage that receives the current feedback signal at both inputs and the voltage feedback signal at one input so as to phase shift the current feedback signal at that one input. The ballast operates instant start or rapid start gas discharge lamps in various configurations, including dimming configurations.

Abstract: A push-pull high voltage oscillator power supply circuit includes a parallel resonant LC circuit made up of a capacitor in parallel with the primary of an output transformer. The output power level of the oscillator is controlled or adjusted by gating a drive circuit of the oscillator in accordance with an appropriate timing scheme so as to control the power delivered to the load over a long time period. The drive circuit is switched on and off so as to control the transformer primary voltage by omitting a number of drive pulses, determined by the desired output pulse level, so that the oscillator self-oscillates and rings out with a decreasing amplitude of the self-oscillats and rings out with a decreasing amplitude of the self-oscillations, but never reaches a complete cut-off of the oscillations before the drive circuit is gated on to refresh the supply of energy to the oscillator. A circuit for monitoring the collector voltages of the switching transistors of the oscillator may be provided to inhibit the supply of drive pulses to the switching transistors when the collector voltages exceed a given voltage level. This limits the power dissipation in the switching transistors.

Abstract: A switching power supply is provided in two stages with the primary of the power transformer being in the first stage and the secondary in the second stage. The first stage includes an EMI filter connected to the input of a rectifier. The output of the rectifier is connected to a self oscillating, half-bridge, resonant inverter operating in open loop with the primary of the transformer to provide isolation from the power source. Feed-forward control is used to compensate for line variations, providing very small output voltage variation compared with input voltage variation. In the second stage, the secondary of the transformer provides an input to post regulator circuitry including a PWM control circuit to regulate the output current using the error signal representing the differences between the current sensed and the desired value.
