Abstract
An optoelectronic semiconductor chip includes a semiconductor layer sequence having an active layer provided for generating radiation. The semiconductor chip can be operated in a first operating mode and in a second operating mode. The semiconductor layer sequence emits radiation in the first operating mode, while the semiconductor layer sequence emits no radiation in the second operating mode. The semiconductor layer sequence is operated in the forward direction in the first operating mode and in the reverse direction in the second operating mode. A display including a number of semiconductor chips of this type and a use as a motor vehicle headlight are furthermore specified.
