PROBLEM TO BE SOLVED: To reduce the power consumption of a display. SOLUTION: A constant current is flowing through a power supply line 12, and in the circuit, the current is branched into a main route, OLED 17, and a bypass route, a 2nd TFT 66 for driving. The currents are joined again via these elements, and re-used for emission of OLED 17 of the next pixel. Also, the control of the light intensity of the OLED 17 is realized by controlling the current flowing through the 2nd TFT 66. |
