Document Type and Number:
WIPO Patent Application WO/2020/166813
Kind Code:
A1
Abstract:
A multi-pixel package according to the present embodiment comprises: a plurality of pixel groups comprising a plurality of each of unit pixels including Red (R), Green (G), and Blue (B) LEDs to which a cathode is commonly connected; and a control circuit for receiving a control signal having a pulse train embedded therein comprising a data signal for controlling luminance of light output by the unit pixels belonging to a pixel group, an activation signal, and a plurality of pulses, wherein the control circuit comprises: a signal separation unit for separating and respectively outputting the activation signal and the pulse train; a charging signal activated by means of the activation signal, and controlling such that each pixel group charges energy for emitting light from the pulse train; a light emission control unit for outputting an emission signal for controlling such that each pixel group emits light from the pulse train; and a pixel group control unit which charges energy provided to the data signal as the charging signal is provided, and controls such that the pixel groups emit light by the emission signal.
