Abstract: A transparent display panel includes: a first substrate, a second substrate, and a liquid crystal layer therebetween. The pixel units of the display panel include a first pixel unit in a first area near one side of the display panel and a second pixel unit in a second area at a side of the first area away from the one side. The first pixel unit includes first and second transparent electrodes on one of the substrates, and the second pixel unit includes third and fourth transparent electrodes on the other one of the substrates. The first pixel unit further includes a dummy electrode separated from both of the first and second transparent electrodes. An orthographic projection of the first or second transparent electrode on the first substrate has a hollow area, and an orthographic projection of the dummy electrode on the first substrate is in the hollow area.

Abstract: The present application relates to a filter module, a color filter, an image sensor and an imaging device. The filter module includes: a plurality of color filters and a control component. Each of the color filters includes: a first substrate; a metasurface structure located on the first substrate and including a plurality of microstructures periodically arranged; a dielectric layer located on a side of the metasurface structure away from the first substrate and covering the metasurface structure, wherein a refractive index of the dielectric layer is different from a refractive index of the metasurface structure; a second substrate located on a side of the dielectric layer away from the first substrate. The control component is configured to adjust the refractive index of the dielectric layer so as to adjust wavelengths of visible light passing through the color filter.
