DISPLAY UNIT AND ELECTRONIC APPARATUS |
摘要 |
A display unit provided with a display panel including a light emitting element and a pixel circuit for each pixel, and a drive circuit configured to drive each of the pixels. The pixel circuit includes: a first transistor configured to sample a voltage corresponding to a picture signal, the first transistor having characteristics that a parasitic capacitance at a time when the first transistor is turned off is decreased as magnitude of negative bias applied to a gate voltage is increased; a second transistor configured to control a current flowing through the light emitting element based on magnitude of the voltage sampled by the first transistor; and a retention capacitance configured to retain the voltage sampled by the first transistor. |
