    Abstract: A method for producing a semiconductor device may include applying one or more semiconductor components onto a device body where the device body has a substrate and an integrated circuit. The semiconductor component(s) may include an active zone configured to receive radiation. The method may further include transferring a multitude of semiconductor components from a sacrificial wafer to a target wafer with the device bodies still coupled by using a stamp to place them onto said device bodies. The stamp may be pressed onto the semiconductor components to adhere to the semiconductor components to the stamp and transfer them. As soon as the stamp moves in the opposite direction, the semiconductor component(s) may be separated from holding structures by breaking away webs or their projections on the second semiconductor body and leaving a breaking point directly on an outside of the semiconductor component.

    Abstract: A method for operating a display device is disclosed. In an embodiment, a method for displaying images or films via a display device includes emitting, for each radiation direction, a partial image composed of sub-pixels of all pixels belonging to this radiation direction and receiving control data for at least some of the sub-pixels at the display device by a data compression algorithm, wherein the data compression algorithm comprises a delta coding, wherein the delta coding includes an initial value, wherein the initial value includes one of the partial images defined as a main image, wherein at least some of the remaining partial images are received as deviations from the main image, and wherein edges of a three-dimensional object to be displayed are excluded from data compression when merging surfaces enclose a real angle of 135° or less.

    Abstract: In one embodiment, an apparatus may include a light source. The apparatus also includes a measuring laser, such as a semiconductor laser. The measuring laser is configured to generate pulses with a maximum pulse duration of 10 ns. A wavelength of maximum intensity of the measuring laser radiation generated by the measuring laser ranges from 400 nm to 485 nm inclusive. The measuring laser radiation is used for distance measurement by means of LIDAR, for example in a car headlight.

    Abstract: A method for manufacturing a multilayer optical element is disclosed. In an embodiment the method includes providing a substrate, applying a first optical layer by applying a first layer having a dielectric first material having a first refractive index, structuring the first layer by sectionally removing the first material and filling first interspaces with a dielectric second material having a second refractive index different from the first refractive index so that the second material has at least the same height as the first material, and applying at least a second optical layer by applying a second layer having the first material, structuring the second layer by sectionally removing the first material so that the first optical layer is exposed in second interspaces between second areas with the first material and filling the second interspaces with the second material so that the second material has at least the same height as the first material.
