Display apparatus and control method thereof

A display apparatus comprising:

• a light emitting element group among a plurality of light emitting element groups of a panel of the display apparatus, the light emitting element group comprising a plurality of light emitting elements, the plurality of light emitting elements comprising a first light emitting element and a second light emitting element;
• a pixel circuit among a plurality of pixel circuits of the display apparatus, the pixel circuit connected to the light emitting element group to supply an image signal to the plurality of light emitting elements;
• and
• a voltage control circuit configured to sequentially supply a reference voltage to the first light emitting element at a first timing corresponding to a first subfield of time of a plurality of subfields of time of a field of time, during which the plurality of pixel circuits receive the image signal for each of the plurality of subfields of time and the voltage control circuit supplies the reference voltage to the plurality of light emitting element groups during each of the plurality of subfields of time, and to the second light emitting element at a second timing corresponding to a second subfield of time of the field of time,
• wherein the first light emitting element is controlled to emit first light corresponding to the image signal at the first timing based on the reference voltage and the second light emitting element is controlled to emit second light corresponding to the image signal at the second timing based on the reference voltage.
