Abstract: An electronic device may have a display mounted in a housing. The display may have a pixel array that produces images. A display cover layer may overlap the pixel array. The display cover layer may have a planar central area surrounded by a peripheral edge area with a curved cross-sectional profile. From an on-axis viewing angle, an image on the pixel array is fully viewable through the planar central area and the peripheral edge area. From an off-axis viewing angle, the image is partly viewable through the peripheral edge area and not through the central area. To avoid an undesired color cast in the partly viewable image seen through the peripheral edge area of the display cover layer, the display may be provided with color cast compensation structures such as a guest-host liquid crystal layer that exhibits an anisotropic colored light absorption characteristic, a diffuser layer, and/or other optical structures.

Abstract: A measuring system for measuring real time groundwater data and graphically depicting the data for analysis and interpretation is disclosed. At least one transducer is positioned in a well to be modeled. A control unit is provided to acquire data from the transducer and to store the data acquired. A home base unit is provided to receive data from the control unit. The home base unit contains a geographic information system program for processing the data. A display unit is connected to the home base unit for displaying the data received.
