Abstract: An optoelectronic device, in particular for the detection of obstacles and/or for distance measurement, may include a transmitting device for emitting laser beams. The transmitting device may include an array of pixels where each pixel of the pixel array comprises at least one laser, such as an optoelectronic laser, e.g. a VCSEL. The pixels of the pixel array may be divided into several sets of pixels, and the transmitting device may be configured to operate the sets of pixels in different, successive time intervals.

Abstract: Display device with of a plurality of pixels (P, P0101, P0102, P0103, P01Y, P0201, P0301, PX01) arranged in an array with rows and columns, a plurality of column lines (C1 . . . CY), each connected to the pixels of one of the columns, a plurality of row lines (L1 . . . LX), each connected to the pixels of one of the rows, a control unit (2) connected to the plurality of column lines and configured to generate a column pulse (CS1 . . . CSY) for a selected one of the plurality of column lines, and connected to the plurality of row lines and configured to generate a data signal (LP1 . . . LPX) for a selected row line from the plurality of row lines, wherein the data signal comprises a set pulse (SP) which, when the pixel is set to a radiating state, is applied at least in part to the pixel connected to the selected column and row line when the column pulse is applied to the pixel, and drives the pixel such that a light emission of the pixel depends on the time offset between the column pulse and the set pulse.
