Abstract: The present invention teaches a pixel unit including thin film transistors (TFTs) and pixel electrodes corresponding to the TFTs. The pixel electrodes are connected to the source electrodes of the TFTs. Each pixel electrode includes multiple arc-shaped electrode units arranged at intervals along an axial direction around a periphery of a corresponding TFT. The electrode units are electrically connected together. The present invention adopts arc-shaped pixels (similar to concentric circles) so that liquid crystal molecules are closer to being isotropic. Then, by having different vertical alignment (VA) TFT designs in the primary pixel region and secondary pixel region and utilizing the differences in W/L and capacitance, different voltage levels for primary pixel electrode and secondary pixel electrode are achieved. The color shift problem is improved and the viewing angle is enhanced.

Abstract: A portable temperature regulation device includes a wearing body and first and second main bodies rotatably connected to the wearing body. The first and second main bodies each include a first housing in which a first receiving chamber is formed to receive a first fan therein. The first main body further includes a first air passage in communication with the first receiving chamber, a first air outlet communicating the first air passage and outside, an air inlet in communication with the first receiving chamber. The first and second main bodies are rotatably connected to the wearing body by a rotation structure. When it needs to fold for storage, the first and second main bodies can be rotated to a folded state, so as to reduce the size of the portable temperature regulation device for easy storage by a user.
