Display apparatus with initialization control and driving method of display apparatus

摘要

A display device includes a driving transistor in a pixel circuit. A signal line is connected to a source or drain of the driving transistor. The source or drain of the driving transistor receives a power source voltage, an initialization voltage, and a data voltage through the signal line during different periods of operation. The periods of operation include an emission and non-emission periods.

1. A display apparatus, comprising:
a first P-type transistor to control an amount of current of a light emitting diode, one of source or drain terminals of the first P-type transistor being connected to an anode of the light emitting diode; a first control line connected to the other of the source or drain terminals of the first P-type transistor, the first control line to supply a gray scale data voltage to set a gate voltage of the first P-type transistor, an initialization voltage to initialize a gate voltage of the first P-type transistor, and an anode voltage for light emission of the light emitting diode; a second P-type transistor to selectively connect the one of the source or drain terminals of the first P-type transistor and a gate terminal of the first P-type transistor; a second control line to supply different levels of voltages; and a capacitive element having a first electrode connected to the gate terminal of the first P-type transistor and a second electrode connected to the second control line.
