Abstract: A display is provided that has upper and lower polarizers, a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer and thin-film transistor layer may be formed from materials such as glass that are subject to stress-induced birefringence. To reduce light leakage that reduces display performance, one or more birefringence compensation layers may be incorporated into the display to help compensate for any birefringence effects. The compensation layers may include a birefringence compensation layer attached to the color filter layer or the thin-film transistor layer. A display may include an upper compensation layer attached to the color filter layer and a lower compensation layer attached to the thin-film transistor layer. The compensation layer may be formed from glass or polymer materials that have a negative photo-elastic constant.

Abstract: A haptic actuator may include a housing having opposing ends and opposing sides extending therebetween. The haptic actuator may also include at least one coil carried by the housing and a field member having opposing ends and opposing sides extending therebetween. The haptic actuator may also include a respective flexure coupling each end of the field member to an adjacent end of the housing so that the field member is reciprocally movable within the housing responsive to the at least one coil over an operating range and while maintaining a respective sidewall clearance between each side of the field member and an adjacent side of the housing. At least one sidewall clearance restricting feature may be configured to restrict the sidewall clearance when the field member moves beyond the operating range when subject to mechanical shock.
