摘要： An information indicator suitable for information processors such as personal computers, word processors and the like includes a light source, a scattering plate which scatters light from the light source, an indicator plate irradiated with scattered light from the scattering plate, and a prism plate operatively arranged with respect to the scattering plate and the indicator plate and having a prism-like protuberance structure formed at a side thereof. The prism plate is so disposed that the prism-like protuberance structure faces the scattering plate, and the angle 2.theta. constituting the prism-like protuberance structure is defined by the formula, 2.theta..ltoreq.2/3.times.(.pi./2+2.times.arcsin (n'/n)), in this inequality, n is the refractive index of said prism plate medium, and n' is the refractive index of a material in which the prism plate is arranged.

摘要： A driving apparatus for a gas discharge display panel having a plurality of cathodes and a plurality of anodes arranged in a matrix includes a cathode pulse generator and an anode pulse generator, with the anode pulse generator generating negative display anode pulses made up of auxiliary discharge pulses (width=tS) and display pulses of smaller pulse width (width=tD, tD.ltoreq.tS) corresponding to information display signals. The anode pulse generator preferably also provides positive display anode pulses so that selection between negative and positive display anode pulses is possible.
