摘要:
A self-luminous display panel driving method for driving a self-luminous display panel of the active matrix driving type, includes the step of executing threshold value correction operation for a driving transistor divisionally in a plurality of periods within at least one of which, after a point of time of an end of a preceding correction period till a point of time of a start of a succeeding correction period, a potential to be applied to the drain electrode of the driving transistor is controlled to an intermediate potential between a first potential for lighting driving of the driving transistor and a second potential for initialization applied within a preparation period of the first one of the correction periods.

In a display apparatus, as shown in FIG. 1, by using a reference signal, a shift register and a logical operation circuit generate a driving signal in periods for correcting a threshold voltage based on a rectangular wave signal. Also by using the reference signal, a write signal in a mobility correcting period is generated by an inverter, a NAND circuit, a level conversion circuit, a buffer circuit, a driving power generating unit, and a low-pass filter including a resistor and a capacitor. The signals are separately generated and are selectively output. Thus, excessive or insufficient mobility correction based on emission brightness can be prevented.

A display device includes pixel array unit and a driver unit. A sampling transistor samples a signal potential to hold the signal potential in a holding capacitor. A driver transistor flows a drive current to a light emitting element in accordance with the signal potential held. A main scanner in the driver unit outputs the control signal having a shorter pulse width than the time period to the scan line to make the sampling transistor conductive during a time period while the signal line is at the signal potential, thereby adding the signal potential a correction for a mobility of the driver transistor when the signal potential is held in the holding capacitor.

A display device includes a pixel array unit and a driver unit. A sampling transistor samples a signal potential to hold the signal potential in a holding capacitor. A driver transistor flows a drive current to a light emitting element in accordance with the signal potential held. A power supply scanner in the driver unit changes a power supply line from a first potential to a second potential before the sampling transistor samples the signal potential. A main scanner in the driver unit makes the sampling transistor conductive to apply a reference potential from the signal line to the gate of the driver transistor and to set the source of the driver transistor to a second potential. The power supply scanner changes the power supply line from the second potential to the first potential to hold a voltage corresponding to a threshold voltage off the driver transistor in the holding capacitor.
