摘要： Disclosed are examples of optical/electrical devices including a variable TIR lens assembly having a transducer, an optical lens and an electrowetting cell coupled to an exterior wall of the lens. The electrowetting cell contains two immiscible liquids having different optical and electrical properties. One liquid has a high index of refraction, and the other liquid has a low index of refraction. At least one liquid is electrically conductive. A signal causes the high index of refraction and the low index of refraction liquids to assume various positions within the electrowetting cell along the exterior wall. The properties of the optical lens, e.g. its total internal reflectivity, change depending upon the position of the respective liquids along the exterior wall. The light characteristics of the assembly change to produce a light beam over a range of light beam outputs or a field of view over a range of fields of view.

A display apparatus includes pixel circuits coupled to the light modulators. Each pixel circuit can include an output node, a data capacitor, a charge transistor for charging the output node and a discharge transistor for selectively conducting a current between the output node and an update interconnect providing an update voltage. The display apparatus can include a controller for testing the pixel circuits to determine two or more update voltage levels, each update voltage level causing the discharge transistor to conduct current. The controller also can be configured to determine a logical high voltage level to be stored in the data capacitor based on the plurality of update voltage levels.
