Displays with phosphorescent components
In example implementations, a display is provided. The display includes a cover lens, a phosphorescent component, a display module and a processor. The phosphorescent component is located adjacent to the cover lens. The display module is located adjacent to the phosphorescent component opposite the cover lens. The processor is communicatively coupled to the display module to cause the display module to generate a desired image that activates corresponding portions of the phosphorescent component before the display is powered down.
Displays with high impedance gate driver circuitry
A touch screen display may include gate line driver circuitry coupled to a display pixel array. The display may be provided with intra-frame pausing (IFP) capabilities, where touch or other operations may be performed during one or more intra-frame blanking intervals. In one suitable arrangement, a gate driver may be operable in a high impedance mode, where the output of the gate driver is left floating during touch or IFP intervals. In another suitable arrangement, the gate driver may be operable in an IFP reduced stress mode, where a digital pass gate in the gate driver is deactivated during IFP intervals. In yet another suitable arrangement, the gate driver may be operable in an all-gate-high (AGH) power-down mode, where the output of each gate driver in the driver circuitry is driven high in parallel when the displayed is being powered off. These arrangements may be implemented in any suitable combination.
