摘要： A current supply circuit according to the present disclosure may include a voltage/current converter configured to convert, into a data current, a data voltage received from a data driving circuit and a first current mirror circuit configured to mirror the data current so that a light-emitting diode (LED) current flows into an LED array. The data current may be adjusted based on a greyscale value of the LED array.
