COLOR IMAGE SENSOR WITHOUT THE COLOR FILTERS

摘要

In various embodiments, image sensors and methods of making images sensors are disclosed. In an embodiment, an image sensor includes a first pixel region having a pixel electrode, an optically sensitive material of a first thickness, and a counterelectrode. The images sensor also includes a second pixel region comprising a pixel electrode, an optically sensitive material of a second thickness, and a counterelectrode. The first pixel region is configured to detect light in a first spectral band and the second pixel region is configured to detect light in a second spectral band. The first and second spectral bands include an overlapping spectral range. The second spectral band also includes a spectral range that is substantially undetectable by the first pixel region. Other image sensors and methods of making images sensors are also disclosed.
