A display device may include first to third semiconductor light-emitting devices in each of a plurality of pixels, a sensing element, and a circuit block in each of the plurality of pixels. The sensing element may include a fourth semiconductor light-emitting device. The first to third semiconductor light-emitting devices may emit light during the first section by a power source having a forward bias. The fourth semiconductor light-emitting device may be light-received by a power source having a reverse bias.

Display device

Discussed is a display device including a substrate, a thin film transistor formed on the substrate, the thin film transistor including a source electrode, a drain electrode, and a gate electrode, and a plurality of semiconductor light emitting devices emitting light so as to each form individual pixels and each having a p-type electrode and an n-type electrode, wherein at least one of the plurality of of the semiconductor light emitting devices is disposed so that one of the p-type electrode and the n-type electrode overlaps the source electrode of the thin film transistor.

Display device using semiconductor light emitting diode and method for manufacturing the same

Discussed is a display device including a substrate, semiconductor light-emitting elements on the substrate, flip-flops which can apply an electrical signal to the semiconductor light-emitting elements to maintain the semiconductor light-emitting elements in a light-emitting state for a predetermined time interval, scan electrodes and data electrodes electrically connected to the flip-flops, respectively, and a driver. When a frame synchronization signal is generated during a time interval from a time point of the generation of a sub field signal to a time point of the generation of a subsequent sub field signal, the driver can prevent a voltage from being applied to the data electrodes for the time interval.
