Abstract: Devices and methods related to high-contrast liquid crystal displays (LCDs) are provided. For example, such an electronic device 10 may include an LCD 18 with two liquid crystal alignment layers 76, 82 not symmetric to one another and upper and lower polarizing layers 66, 68 respectively above and below the alignment layers 76, 82. Light transmittance through the plurality of pixels 42 may increase monotonically with gray scale voltage. The display 18 may operate using a gray scale level 0 voltage higher than a minimum gray scale level 0 voltage capability of the display. Additionally or alternatively, liquid crystal molecular alignment axes 110 of the two alignment layers 76, 82 may be offset from one another by an angle other than a multiple of 180 degrees. Additionally or alternatively, a first polarizing axis of the upper polarizing layer 66 or a second polarizing axis of the lower polarizing layer 68, or both, may be neither parallel nor perpendicular to one of the liquid crystal molecular alignment axes 110.

Abstract: Aspects of the present disclosure relate to single-domain electrode configurations that may be implemented in the unit pixels 60 of a LCD device 34, such as a fringe field switching (FFS) LCD, to provide a "pseudo-multi-domain" effect, wherein the benefits of both conventional single-domain and multi-domain pixel configuration devices are retained. In accordance with aspects of the present technique, single-domain unit pixels 60 are angled or tilted in differing directions with respect to a vertical axis of the LCD panel (e.g., y-axis) to provide an alternating and/or periodic arrangement of different-angled pixel electrodes 110 along each scanning line, data line, or a combination of both scanning and data lines. In this manner, the transmittance rates of conventional single-domain LCD panels 34 may be retained while providing for improved viewing angle and color shift properties typical of conventional multi-domain LCD panels.

Abstract: Common electrodes (Vcom) of integrated touch screens can be segmented into electrically isolated Vcom portions that can be operated as drive lines and/or sense lines of a touch sensing system. The touch screen can include high-resistivity connections between Vcom portions. The resistivity of the high-resistivity connections can be high enough so that touch sensing and image display can be performed by the touch screen, and the high-resistivity connections can provide an added functionality by allowing a charge build up on one of the Vcom portions to be spread to other Vcom portions and/or discharged from system by allowing charge to leak through the high-resistivity connections. In this way, for example, visual artifacts that result from charge build up on a Vcom portion can be reduced or eliminated.

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 adaptively adjust the display output based on ambient lighting conditions. For example, in cooler ambient lighting conditions such as those dominated by daylight, the display may display neutral colors using a relatively cool white. When the display is operated in warmer ambient lighting conditions such as those dominated by indoor light sources, the display may display neutral colors using a relatively warm white. Adapting to the ambient lighting conditions may ensure that the user does not perceive color shifts on the display as the user's vision chromatically adapts to different ambient lighting conditions. Adaptively adjusting images in this way can also have beneficial effects on the human circadian rhythm by displaying warmer colors in the evening.
