摘要:
Pixels of a display system may comprise light emitting elements whose light output levels are set based on image data as well as background areas whose light reflectance levels are set based on the same image data. These light output levels and/or light reflectance levels may also be adjusted based on an ambient light level. The background areas may comprise light reflective elements which may be controlled individually or as a whole. The light output levels of the light emitting elements and the light reflectance levels of the light reflective elements are configured to generate collectively a pixel value for the pixel dependent on the image data. One or more modulation algorithms may be used to control the energy consumption, dynamic range, color gamut, point-spread function, etc., of the pixels in the display system.

A pixel structure for a vertical emissive-reflective (emi-flective) display is provided. The pixel structure has a substrate, a self-light emitting pixel unit arranged on the substrate, and a reflective pixel unit arranged on the self-light emitting pixel unit. By using the vertical pixel structure, the aperture of the display can be increased, and the power consumption can also be decreased.

A color liquid crystal display including a back light module and a liquid crystal display (LCD) panel disposed thereon is provided. The back light module has a plurality of light sources emitting different kinds of color lights. The LCD panel includes an active device array substrate, an opposition substrate, and a liquid crystal layer. The opposition substrate is disposed above the active device array substrate, and the liquid crystal layer is disposed between the opposition substrate and the active device array substrate. Both the active device array substrate and the opposition substrate do not have a color filter layer. Therefore, the LCD has better light utility.

摘要:
An EL element (33) is provided on a first substrate (1) to make it possible to perform both light emission display according to the EL element (33) and reflective display according to a liquid crystal display element. An EL control switching element (17) and a liquid crystal layer switching element (18) are provided on a face of the first substrate (1) positioned on the side of a liquid crystal layer (51). The EL control switching element (17) is connected to an anode electrode (21) or a cathode electrode (24) constituting the EL element (33). By connecting the liquid crystal layer switching element (18) to a display electrode (31) and a reflective electrode (28) constituting a liquid crystal display element, a liquid crystal display element and a light emitting element are integrated in a liquid crystal display device incorporated with the liquid crystal display element therein, so that thinning and weight reduction are achieved considering electrical connection therebetween and both reflective display and transmissive display are made possible.
