Abstract: A visual display has a cathode plate 101, having an emission layer 102 built up on a ceramic front layer. It has a thicker foundation layer 103. Vias from the front layer have their pitch fanned out to that of the cathode-plate back-layer vias 104. Other main components of the visual display are a frame 111, a back plate 112 and an anode 114 plate. The back plate and the frame are integrally formed of a number of layers of tape cast ceramic material. The back plate has a via and interconnect fan-out. The frame also has a via and interconnect arrangement for making electrical connection to the anode plate.

Abstract: The invention relates to a power control structure comprising a switching mode power amplifier for receiving an input signal, for amplifying the received input signal and for providing the amplified signal as output signal. In order to enable a power control over a large range while preserving the efficiency of the power amplifier, the structure further comprises a first control arrangement for controlling the power level of the output signal at least at higher desired power levels by adjusting a power supply provided to the switching mode power amplifier, and in addition a second control arrangement for controlling the power level of the output signal at least at lower desired power levels by adjusting the power of the input signal before it is provided to the switching mode power amplifier. The invention relates equally to a corresponding method.
