Display apparatus, driving method thereof, and electronic system
A display apparatus includes: a pixel array section including a row of scanning lines, a column of signal lines, and pixels in a matrix, each of the pixels disposed at an intersection of both of the lines; and a drive section. The drive section performs line progressive scanning on the pixels. The pixel includes a light emitting device, a sampling transistor, a driving transistor, a switching transistor, and a holding capacitor. The sampling transistor samples a video signal in the holding capacitor, the driving transistor changes the device to a luminous state, the switching transistor becomes ON in advance of the sampling of the video signal to change the light emitting device to a non-luminous state, and the sampling transistor takes in the OFF voltage from the signal line to the driving transistor, thereby preventing a penetration current from flowing from the power source toward the fixed potential.
1 . A pixel circuit disposed at intersection of a scanning line and a signal line, the pixel circuit comprising:
a light emitting device;
a sampling transistor
a driving transistor
a switching transistor, and
a holding capacitor,
wherein the switching transistor provides a fixed potential to the holding capacitor to change the light emitting device to a non-luminous state, and
the sampling transistor provides OFF voltage from the signal line to the driving transistor.
2 . The display apparatus including the pixel circuit according to claim 1 .
