Abstract: A system may include a display having a housing, a cover lens coupled to the housing, a light plate assembly in the housing, a diffuser that overlaps the light plate assembly, a louver layer that overlaps the diffuser, and a ring light source that emits additional light around the periphery of the light plate assembly and through the cover lens. The light plate assembly may include an array of light-emitting components. To improve the efficiency and contrast of the light plate assembly, reflective fill material may be formed around each light-emitting component, and absorptive fill material may surround the reflective fill material. The absorptive fill material may absorb ambient light, while the reflective fill material may redirect stray light out of the display. Dam material may surround the absorptive fill material and/or the reflective fill material.

Abstract: The disclosure discloses a method for preparing a nanoscale cationic hyperbranched starch-based gene carrier, which mainly includes the following steps: heating and gelatinizing a dextrin solution, then obtaining a highly branched cluster dextrin molecule having abundant short chains through hydrolysis and transglycosylation of starch branching enzymes, and then performing an etherification reaction to obtain cationic polymers with different degrees of substitution. The polymer is controllable in degradation, the highly branched structure thereof can reduce the requirement of the gene carrier on the high degree of substitution of cationic starch to a certain extent, and the cytotoxicity is obviously reduced. In addition, the polymer carrier can form a stable nanocomplex with a gene fragment, and has wide application in gene therapy as an efficient gene carrier.
