Abstract
The embodiments of the present invention provide a color filter integrated with a sensor array and methods of fabricating the same. By integrating the sensor array with the color filter, the overall cost of the display is reduced. Moreover, the integration allows the sensor array to be used like a touch screen for data input. As a further benefit, the integration allows the color filter to serve as a light shield thus eliminating the need for a separate light shield for the sensor array.

24. A display, comprising:
-
a display component comprising a plurality of subpixels organized in groups and formed on a first substrate, each subpixel in a group being associated with a different color; and
a filter component, comprising;
a plurality of color filter elements organized in groups and formed on a second substrate, each group of color filter elements corresponding to a respective group of subpixels in the display component, each color element in a group being associated with a different color; and
an array of sensors formed on the second substrate and aligned with the plurality of subpixels and with the plurality of color filter elements; and
wherein each sensor has an associated electrical parameter dependent on a level of light emissions received from a respective subpixel thereby an electrical feedback parameter or signal dependent on the received level of light emissions is used to control the luminance of the respective subpixel - View Dependent Claims (25, 26, 27)
