  • Patent number: 10523910
    Abstract: A display system and method created by adjusting the properties of one or more displays to obtain coarse control over display behavior, by using sensors to optimize display parameters and meet a quality target. The display may construct a display map by selectively driving the display and sensing the optical image created. The system reports on its status, and is able to predict when the system will no longer meet a quality target. The system and method may optimize a display system and keep it optimized over time. Operators of the display who require a minimum level of quality for the display system can be ensured that the display meets those requirements. And, they can be warned in advance as to when system maintenance can be necessary, when quality falls below targeted goals system and method provides for sending out methods of the quality of the system.
