Title: Display device
Inventor: NAKAMURA TAKU
IPC: G09G3/36
Filed: 2001-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a display device whose power consumption is reducible. SOLUTION: In this display device, a signal line driving circuit 5 has a changeover circuit 31 which is connected in parallel with a resistance element Rdr on power source supplying lines. This changeover circuit 31 is controlled so as to be changed over by the output of a comparator 32. The comparator 32 compares the voltage XAVDD' of the connection path of resistances Rd, Rdr with a reference voltage (5 V), and when the voltage XAVDD' is larger than the reference voltage (5 V), the comparator 32 short-circuits both ends of the resistance element Rdr by turning the circuit 31 ON.  Since the impedance on the power source supplying lines which supply a power source voltage to an amplifier 17 is adjusted in accordance with the threshold voltage of a TFT (thin film transistor) on a glass substrate in this manner, a current does not flow wastefully through the power source supplying lines and the reduction of the power consumption is attained in this display device.
