One way might be with plasma panels, which are effectively their own memory. Each dot on the display is similar to a neon bulb, with an anode and a cathode and neon gas in the gap between. Dots are turned on with a short higher voltage pulse and then continue to glow because of a constant background voltage. The initial pulse ionizes the neon in the gap, which then stays lit using the lower "maintaining" voltage. I assume the problem with building a high resolution display with a plasma panel would be that as the cell size goes down it gets dimmer. I wonder what the practical limits are for the narrowness of the gap between the cathode/anode in a plasma panel and or the closest spacing between cells? (do existing panels isolate the display cells with walls of a dielectric?) Or we might be limited by the amount of energy to be dissapated in each cell (the glow of the glass panel cannot be brighter than the cells in it...) Or how about other technologies; liquid crystal and electroluminescent to name two? The Grid/Compass portable computer (or workstation if you prefer) has an electroluminescent display of low resolution. (ron) -------
