摘要： The present invention describes a liquid crystal composite tuneable device for fast polarisation-independent modulation of an incident light beam comprising: (a) two supporting and functional panels, at least one of them coated with a transparent conductive electrode layer and with optionally at least one additional layer selected from an alignment layer, antireflective coating layer, thermochromic or electrochromic layer, photoconductive or photosensitive layer, and (b) a composite structure sandwiched between said two panels and made of a liquid crystal and porous microparticles infiltrated with said liquid crystal. The porous microparticles have an average refractive index approximately equals to one of the liquid crystal principal refractive indices, matching that of the liquid crystal at one orientational state (for example, parallel n∥), and exhibiting large mismatch at another orientational state (for example, perpendicular n⊥). This refractive index mismatch between said microparticles and said liquid crystal is tuned by applying an external electric or magnetic field, thermally or optically.

摘要： A liquid crystal display (LCD) includes several transparent material layers and several non-transparent material layers that are disposed in a stacked mode. The LCD also has a local transparent region, and no non-transparent material is applied to the several non-transparent material layers in the local transparent region. This forms a transparent channel in the local transparent region along a stacking direction. An optical component is completely or partially disposed in the transparent channel of the LCD display. The optical component may be a camera, an ambient light sensor, an optical fingerprint sensor, or another component disposed under the display by using the local transparent region on the LCD display.
