Abstract
A method for driving a display panel, in which a false gaseous discharge of a display cell is prevented via an initialization sequence containing a reset pulse and an initialization pulse. Stable initialization is achieved by applying the initialization pulse to the common electrode after the reset pulse. The initialization pulse rises up in one step. Alternatively, the initialization pulse is a complex pulse having second-step pulse that rises up within 1 μs after the rise of its first-step pulse. A stabilization sequence can be inserted between the initialization sequence and a discharge maintenance sequence.
Claims11
A method for driving a display panel, in which a common electrode and a discrete electrode are connected to one of plural display cells arranged in a matrix form, the method comprising the steps of:
- (a) supplying said common electrode with a reset pulse opposite in polarity to a display pulse, the reset pulse for inversion of charges stored on said common electrode;
- (b) supplying said common electrode with a first single-step pulse of the same polarity as said display pulse;
- (c) applying said display pulse to the common electrode;
- and
- (d) applying a control voltage to said discrete electrode to thereby control a gaseous discharge in said one of plural display cells.
A method for driving a display panel, in which a common electrode and a discrete electrode are connected to one of plural display cells arranged in a matrix form, the method comprising the steps of:
- applying a display pulse to the common electrode;
- applying a control voltage to the discrete electrode to thereby control a gaseous discharge in said one of plural display cells;
- and
- transferring data, for controlling a period of the gaseous discharge in said one of plural display cells, to a drive circuit of the discrete electrode substantially when no voltage is applied to the common electrode.
A method for driving a display panel, in which a common electrode and a discrete electrode are connected to one of plural display cells arranged in a matrix form, the method comprising the steps of:
- (a) applying an initialization sequence voltage to the common electrode;
- (b) applying a stabilization sequence in which at least one display pulse is applied to the common electrode to perform a stabilizing gaseous discharge of each of said plural display cells;
- and
- (c) controlling a period of the gaseous discharge in said one of plural display cells by controlling a period in which to apply said display pulse to the common electrode and in which to apply a discharge suppression pulse to the discrete electrode.
A method for driving a display panel, in which a common electrode and a discrete electrode are connected to one of plural display cells arranged in a matrix form, the method comprising the steps of:
- (a) removing charges that trigger an unintended discharge of the one of plural display cells during a stabilization period in which voltages are not applied to either the common electrode or the discrete electrode;
- (b) applying a display pulse to the common electrode to perform a gaseous discharge of said display cell;
- and
- (c) controlling a period of the gaseous discharge in said one of plural display cells by controlling a period in which to apply said display pulse to the common electrode and in which to apply a discharge suppression pulse to the discrete electrode.
