Abstract (en)

[origin: WO2004053825A1] A display comprises a plurality of pixels (2) arrayed like a matrix, and each of the pixels (2) comprises a voltage signal input terminal (E) which is supplied with a voltage signal, a drive control device (Tr), a capacitor (C1), a current signal input terminal which is supplied with a current signal, a first switch (Sw5b), a second switch (Sw5a), an output control switch (Sw2), and a display device (20). The drive control device (Tr) comprises a first terminal connected to a first power terminal (11), a control terminal, and a second terminal for outputting a current corresponding to the voltage between the terminals. The capacitor (C1) is connected between the voltage signal input terminal (E) and the control terminal. The first switch (Sw5b) is connected between the current signal input terminal and the control terminal. The second switch (Sw5a) is connected between the current signal input terminal and the second terminal. The input terminal of the output control switch (Sw2) is connected to the second terminal. The display device (20) is connected between a second power terminal and the output terminal of the output control switch (Sw2).
