Abstract: A display device includes a substrate, a first light emitting element, a second light emitting element, and an optical film sheet. The first light emitting element and the second light emitting element are disposed on the substrate. The first light emitting element emits a first light, and the first light has a first wavelength range. The second light emitting element emits a second light, and the second light has a second wavelength range. The optical film sheet is disposed above the first light emitting element and the second light emitting element. The optical film sheet includes a first zone and a second zone. The first zone includes a first cholesteric liquid crystal, and the first cholesteric liquid crystal reflects light in at least the first wavelength range. The second zone includes a second cholesteric liquid crystal, and the second cholesteric liquid crystal reflects light in at least the second wavelength range.

Abstract: A heat dissipation device includes a main fixed base plate, a main heat pipe set, a lower heat dissipation fin set and an upper heat dissipation module. The main heat pipe set is fixed on the main fixed base plate, and the lower heat dissipation fin set is also fixed on the main fixed base plate, and the main heat pipe set passes through the lower heat dissipation fin set, and is exposed on the lower heat dissipation fin set. In addition, the upper heat dissipation module is detachably installed on the lower heat dissipation fin set and contacts the main heat pipe set.

Abstract: An embodiment of this invention A NiO chip is provided. The NiO chip includes a substrate, a nickel oxide thin film on the substrate, and a bioprobe layer on the nickel oxide thin film. The nickel oxide thin film has a light transmittance of more than 60% and a nanostructure. The bioprobe layer includes a plurality of bioprobes modified by Histidine (His) or a His-tagged protein.
