1. An organic light emitting element (OLED) display system disposed in an object, the system comprising:
an OLED display including a first organic light-emitting layer and a second organic light-emitting layer, the first organic light-emitting layer configured to emit light to an exterior of the OLED display system through the second organic light-emitting layer; and
a controller controlling on/off of at least one of the first organic light-emitting layer and the second organic light-emitting layer based on a speed of the object received from a speed sensor of the object,
wherein the second organic light-emitting layer has a larger beam angle than the first organic light-emitting layer, and
the controller is configured to increase an amount of a current applied to the first organic light-emitting layer to increase bright luminance provided by the first organic light-emitting layer when the speed of the object increases from a predetermined reference speed.
