  • Publication number: 20240135861
    Abstract: The present disclosure provides a display apparatus including an LED array. The display apparatus comprises a light emitting diode (LED) array, a power source, a controller, a PWM switch, and a current source module. The controller is configured to generate a control signal for controlling a first LED column during a scan period. The PWM switch is electrically connected between the first LED column and a second power level. The current source module is electrically connected between the first LED column and the second power level. The current source module is configured to provide a current flow with multiple levels. The PWM switch is controlled based on a first portion of the control signal, and the amount of the current flow provided by the current source module in the scan period depends on a second portion of the control signal.
