Abstract: The present disclosure provides methods and systems for detecting multiple different nucleotides in a sample. In particular, the disclosure provides for detection of multiple different nucleotides in a sample utilizing fewer detection moieties than the number of nucleotides being detected and/or fewer imaging events than the number of nucleotides being detected.

Abstract: A device includes a liquid crystal display panel, a compression pad, and a bottom chassis. The bottom chassis supports the liquid crystal display panel. The compression pad has a first surface facing the liquid crystal display panel and a second surface opposite the first surface. The second surface faces away from the liquid crystal display panel. The compression pad substantially fills a volume between the liquid crystal display panel and the bottom chassis. Also, a method of assembling a device includes providing a liquid crystal display panel having a display module reflector, aligning a compression pad assembly with the liquid crystal display panel, and removing a compression pad liner from the compression pad. The compression pad assembly includes the compression pad and the compression pad liner.
