Patent ID: 8094252

Claim:
A method of driving a display apparatus that is formed by arranging display devices each having a driving circuit and a current-driven type light emitting portion in a two dimensional matrix pattern in row and column directions, the driving circuit including at least a driving transistor having a gate electrode and source/drain regions, and a current flowing in the light emitting portion through the source/drain regions of the driving transistor, the method comprising the steps of: when the number of rows of the display devices is denoted by M, the number of the display devices configuring each row is denoted by N, and a time calculated by dividing a total time for scanning the display devices of the first row to the M-th row for each row by M is denoted by a unit time t 0 , performing a threshold voltage cancelling process in units of a display device row in which a predetermined reference voltage is applied to the gate electrode of the driving transistor of Q×N display devices configuring groups of the display device rows and a predetermined driving voltage is applied to one source/drain region of the Q×N display devices so as to change the electric potential of the other source/drain region toward an electric potential calculated by subtracting a threshold voltage of the driving transistor from the reference voltage during a period T Q that is represented by a product of the number Q of a plurality of the display device rows configuring each group of the display device rows, which is acquired by dividing the display devices of the M rows into a plurality of groups of the display device rows, and the unit time t 0 ; and sequentially performing a writing process, in which video signals are applied to the gate electrodes of the driving transistor of N display devices configuring the display device row, Q times, wherein the writing process is sequentially performed Q times within a period not exceeding a half of the period T Q , and the threshold voltage cancelling process is performed such that a length of a period from the end of the threshold voltage cancelling process to the start of the writing process is constant in each display device row configuring the group of the display device rows.
