Abstract
A dimmable display lens system and method is provided which includes a display element configured to emit light. The system and method also includes a dimmable lens disposed in the direction of light emission of the display element and configured to increase the transmission of light emitted by the display through the dimmable lens. The dimmable lens also includes a control system configured to increase the transmission of light emitted by the display according to a plurality of light transmission incremental steps. The control system includes a feedback control system configured to adjust the transmission of light through the dimmable lens based at least on the measured values of an ambient light sensor and a forward looking light sensor.
Claims20
A dimmable display lens system, the system comprising:
- a display element, the display element configured to emit light;
- and
- a dimmable lens, the dimmable lens disposed in the direction of light emission of the display element and configured to increase the transmission of light emitted by the display element through the dimmable lens,
- wherein the dimmable lens includes a control system configured to increase the transmission of light emitted by the display according to a plurality of light transmission incremental steps,
- wherein the control system includes a feedback control system configured to adjust the transmission of light through the dimmable lens based at least on the measured values of an ambient light sensor and a forward looking light sensor.
A method of controlling a dimmable display lens disposed in the direction of light emission of a display element, the method comprising:
- setting the light emission of the display element to a constant value;
- generating a look up table containing a plurality of light transmission incremental steps using a minimum transmission level of the dimmable display lens, a maximum transmission level of the dimmable display lens, a predetermined number of light transmission incremental steps;
- selecting a light transmission incremental step from the look up table;
- and
- adjusting the transmission of light emitted by the display element through the dimmable display lens according to the selected incremental step.
A non-transient computer readable medium containing program instructions for causing a computer to perform the method of:
- setting the light emission of the display element to a constant value;
- generating a look up table containing a plurality of light transmission incremental steps using a minimum transmission level of the dimmable display lens, a maximum transmission level of the dimmable display lens, a predetermined number of light transmission incremental steps and a selected light transmission incremental step;
- and
- adjusting the transmission of light emitted by the display element through the dimmable display lens according to the selected incremental step.
