摘要:
An organic EL display device driven by thin-film transistors is disclosed, wherein for suppressing the deterioration with time of thin-film transistors, at least one of the thin-film transistors, or a second thin-film transistor is formed of a p-channel type thin-film transistor. The p-channel type thin-film transistor has been formed in the same step of process as the thin-film transistors in built-in drive circuits.
摘要:
A transistor circuit is provided including a driving transistor where conductance between the source and the drain is controlled in response to a supplied voltage, and a compensating transistor where the gate is connected to one of the source and the drain, the compensating transistor being connected so as to supply input signals to the gate of the driving transistor through the source and drain. In a transistor circuit where conductance control in a driving transistor is carried out in response to the voltage of input signals, it is possible to control the conductance by using input signals of a relatively low voltage and a variance in threshold characteristics of driving transistors is compensated. With this transistor circuit, a display panel that can display picture images with reduced uneven brightness is achieved.
