Abstract:
1. A method applied on an active matrix display having a matrix of pixel elements, an array of column conducting lines, and an array of row conducting lines crossing the array of column conducting lines, wherein a pixel element comprises a nonlinear element having a first terminal electrically connected to a column conducting line, a resistive element having a first terminal electrically connected to a row conducting line, and a capacitive element having a first terminal electrically connected to the column conducting line through the nonlinear element, wherein the nonlinear element is configured to function as a two-terminal switching element having the conductivity thereof controllable with a voltage across thereof or a current passing through, the method comprising: forming a row of selected pixel elements in the matrix of pixel elements, wherein the forming a row of selected pixel elements comprises driving the nonlinear element in each selected pixel element into a conducting state; forming non-selected pixel elements in multiple rows of pixel elements, wherein forming a given non-selected pixel element comprises driving the nonlinear element in the given non-selected pixel element into a non-conducting state; and charging multiple selected pixel elements in the row of selected pixel elements, wherein charging a given selected pixel element comprises passing a current through the resistive element in the given selected pixel element with a current value individually predetermined for the given selected pixel element to generate a voltage value across the resistive element that is substantially independent upon the current-voltage characteristics of the nonlinear element and to charge the capacitive element in the given selected pixel element to a target voltage that is substantially independent upon the current-voltage characteristics of the nonlinear element but having the target voltage substantially depend upon the resistive value of the resistive element.
