Abstract
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.
Claims3
-4. (canceled)
A display apparatus comprising:
- a pixel section having pixels arranged in a matrix;
- and
- a driving circuit configured to drive the pixel section,
- wherein each pixel includes
- a light-emitting element,
- a capacitor,
- a write transistor configured to be turned on and off by a write signal output from the driving circuit, and
- a driving transistor having a gate and a source to which ends of the capacitor are connected,
- wherein the driving circuit includes
- a selective output unit configured to selectively output, to the pixel, the write signal generated by using a pulse signal and the write signal generated by smoothing a rising edge and/or falling edge of the pulse signal.
The display apparatus according to claim 1, wherein the write transistor configured to set a terminal voltage of the capacitor to a signal level, and
- wherein a driving transistor having a gate and a source to which ends of the capacitor are connected, the driving transistor configured to cause the light-emitting element to emit light by driving the light-emitting element in accordance with the terminal voltage of the capacitor.
