LIGHT EMITTING APPARATUS CAPABLE OF SUPPRESSING NOISE

摘要

A light emitting apparatus capable of suppressing noise includes: a plurality of light emitting chips and a drive circuit. Each light emitting chip includes a plurality of light emitting units and a scanning circuit. The scanning circuit is electrically connected to the light emitting units, so as to receive a frequency signal combination, and sequentially scans the light emitting units so as to selectively enable the scanned light emitting units to emit light. The drive circuit is electrically connected to the light emitting chips, to provide a frequency signal combination for each light emitting chip. The frequency signal combinations are grouped into a plurality of groups. At least two of the groups have a delay therebetween, so that the light emitting units corresponding to a same serial number emit light successively according to the delay.
