Patent ID: 7333078

Claim:
A display system comprising: a matrix of electroluminescence elements arrayed in a plurality of rows and columns; a plurality of cathodes and anodes corresponding to the electroluminescence elements; a plurality of cathode lines electrically connected to the cathodes on the rows in the matrix; a plurality of anode lines electrically connected to the anodes on the columns in the matrix, the anode lines including a first anode line and a second anode line; a column equalization bus electrically connectable to the anode lines; and a control circuit to concurrently: (i) electrically isolate the column equalization bus from any active power source, (ii) connect the first anode line to the column equalization bus, and (iii) connect the second anode line to a power source for a time period corresponding to grayscale or color display data, to light at least one of the electroluminescence elements connected to the second anode line for display, and, after the time period, disconnecting the second anode line from the power source and connecting the second anode line to the column equalization bus to share charge with the first anode line.
