PURPOSE: A light-emitting diode (LED) driving device is provided to reduce power consumption by reducing the voltage level of data. CONSTITUTION: A data switch (P2) is activated in an initialization section, a sampling section, and a compensation section, and the source terminal of the data switch is connected to a data line. A constant-current device (P1) is equipped with a source terminal, a drain terminal, and a gate terminal. A first storage device is connected between the drain terminal of the data switch and the gate switch of the constant-current device. A sampling switch (P3) is connected between the gate terminal and drain terminal of the constant-current device and activated in the sampling section. An LED driving switch (P4) applies a current from the constant-current device to an LED. |
