A liquid crystal optical device providing refractive Fresnel lens type element control over light passing through an aperture is provided. The device includes a layer of liquid crystal material contained by flat substrates having flat alignment layers; and an arrangement of electrodes configured to provide a spatially varying voltage distribution within a number of lensing zones within said liquid crystal layer. The arrangement of electrodes includes ring-shaped electrodes defining boundaries between Fresnel lensing zones. The liquid crystal optical device is structured to provide a spatial variation in the optical phase delay with an abrupt transition at a boundary between lensing zones to increase the effective aperture of the optical device.

An electronic paper device includes a touch cover plate module, a front lighting module and an electronic paper display module. The touch cover plate module has a top plate, a touch sensor and a bottom plate. The top plate is disposed with a black bezel. The bottom plate is disposed with a transparent conductive film with a low refractive index. The front lighting module has a light guide plate. An outer edge portion of the light guide plate is disposed with a point light source.
