Abstract: Techniques are disclosed for utilizing an etchant-accessible carrier substrate that enables etching through the carrier substrate. More particularly, an etchant is provided access to the adhesive layer via the etchant-accessible carrier substrate via one or more holes in the etchant-accessible carrier substrate.

Abstract: Techniques are described for operating a display comprising an array of emitters arranged in at least one column. A data shifting circuit stores digital data or an analog representation thereof in a first storage element. The data shifting circuit outputs the digital data or analog representation multiple times to a display driver circuit, using a multiplexer. The first storage element can be a shift register or a capacitor. Digital data can be internally shifted within the data shifting circuit, through multiple shift registers, prior to output to the display driver circuit. An analog representation can be stored and read from the same capacitor without internal shifting. The display driver circuit drives a different emitter of the column each time. A scanning assembly including a reflective surface that receives light from the emitter array forms an output image by rotating the reflective surface in synchronization with driving of the emitters.
