The present invention discloses a biological detection device and a detecting method. The biological detection device comprises a substrate, an electric field unit, a liquid crystal/polymer composite film (LCPCF), a power supply, a processing unit, and an image sensor. Because of the electrically tunable orientations of the liquid crystal (LC) director anchored among the polymer grains, the wettability of the LCPCF changes with an applied electric field. As a result, we can manipulate a blood droplet on the LCPCF by a wettability gradient owing to the distribution of LC directors on the LCPCF. The motion states of the blood droplet can be related to the various qualities of the blood, and finally determines the health of the test sample. The change of contact angle of blood on LCPCF and the blood droplet motion on LCPCF indicate the concentration of TG and the concentration of HDL.

A liquid crystal (LC) lens comprises a first substrate, a first electrode structure, an electrically tunable LC layer structure, a second substrate and a second electrode structure, wherein the electrically tunable LC layer structure is arranged between the first substrate and the second substrate. The electrically tunable LC layer structure includes at least two LC layers stacked on top of one another, and each LC layer further includes at least one LC unit. In the stacked structure, at least one of the LC layers includes at least one partition unit to partition the LC layer into one or more LC units. The layout of the LC units of the upper LC layer differs from that of the lower LC layer. In the present invention, the shape and layout of the LC units are designed to provide better optical performance without changing the thickness of the liquid crystal lens.

An optical system for aberration compensation comprising an optical module and an asymmetric refractive index distribution film is disclosed. The asymmetric refractive index distribution film comprises a liquid crystal and a liquid crystalline polymer, wherein the asymmetric refractive index distribution film set on an out-light surface or an in-light surface of the optical module. A display system comprising the above-mentioned optical system and an image panel are also disclosed herein. The asymmetric refractive index distribution film of the present invention has non-uniform refractive index distribution so as to effectively compensate the aberration formed by the optical module.
