  • Driving method of light emitting diodes
    Patent number: 9357603
    Abstract: A driving method is applied to a driving switch having a first terminal, a second terminal coupled to a first light emitting diode (LED), and a control terminal. First, supply a reset voltage to the control terminal. When the second terminal electrically connects with the control terminal and the first terminal receives a precompensation voltage, the difference between the voltage at the control terminal and the preset voltage is equal to the threshold voltage of the driving switch. When the second terminal electrically connects with the control terminal and the first terminal receives a data voltage, the difference between the voltage at the control terminal and the data voltage is equal to the threshold voltage of the driving switch. When the first terminal receives a power voltage, a driving current is generated according to the voltage at the control terminal and the power voltage to drive the LED.
