Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may operate the display in different modes. In a paper mode, display control circuitry may use stored spectral reflectance data to adjust display colors such that the colors appear as they would on a printed sheet of paper. In a low light mode when the ambient light level is below a threshold, the light emitted from the display may be adjusted to mimic the appearance of an incandescent light source. In a bright light mode when the ambient light level exceeds a threshold, the light emitted from the display may be adjusted to maximize readability in bright light. The target white point of the display may be adjusted based on which mode the display is operating in.

Abstract: A display may have an array of pixels. The display may be controlled using display driver circuitry. The display driver circuitry may analyze image data to be displayed on the array. When static content is detected, the rate at which the pixels are refreshed may be adjusted to conserve power. If a static image is detected, the gate lines may be asserted at a lower refresh rate than if moving content is detected. To avoid visible artifacts, the display driver circuitry may use temporal and spatial refresh rate buffers. Temporal buffers ensure that refresh rates are changed gradually as a function of time, thereby minimizing flicker. Spatial refresh rate buffers are used to provide a smooth transition between low refresh rate and high refresh rate regions in a display as a function of position.

Abstract: A polarizer integrated with conductive material and a process for forming a polarizer integrated with conductive material are disclosed. A polarizer can be integrated with conductive material to form a portion of a touch sensor panel. In one example, a layer of conductive film forming either the row or column traces can be patterned on a surface of a substrate in the polarizer. In another example, the layer of conductive film can be patterned on a viewing angle compensation film of the polarizer. One or more of the polarizer's polarizing layer, protective substrates or viewing angle compensation film can act as a dielectric between the conductive material forming the rows and column traces in the stack-up. As a result, the clear polymer spacer acting as a dielectric in touch panels can be removed, reducing the thickness of the touch screen stack-up.

Abstract: An electronic device may have a touch screen display or other input-output device that includes transparent conductive electrodes. The transparent conductive electrodes may be formed from a material that has a relatively high index of refraction such as indium tin oxide. Surrounding layers of the touch screen display such as a touch sensor substrate and an underlying display layer may have lower index of refraction values. To prevent abrupt index-of-refraction discontinuities that lead to unwanted reflections and visible artifacts on the display, the transparent conductive electrodes may be embedded within a dielectric layer. The dielectric layer may have a graded index of refraction. The graded index of refraction may be varied continuously or in a stepwise fashion by adjusting the composition of materials that are incorporated into the dielectric layer as a function of position within the layer.
