摘要： A dual mode capacitive touch panel includes a sensor substrate, an electrode layer comprising an array of sensor electrodes arranged over the sensor substrate, the array of sensor electrodes including a plurality of drive electrodes and a plurality of sense electrodes, each sensor electrode corresponding to a location on the sensor substrate, and a shield layer arranged over and spaced apart from the electrode layer. The shield layer includes a predetermined resistance that permits transmission of an electric field at a first frequency and prevents transmission of an electric field at a second frequency, wherein a spacing between the shield layer and the electrode layer is deformable as a result of a force applied to the shield layer due to a user touch, wherein the deformation alters a capacitance between the shield layer and a sensor electrode of the array. A controller is operatively coupled to the array of sensor electrodes, the controller configured to drive the shield layer and at least some sensor electrodes of the sensor electrode array at the first frequency in a first mode to measure a location of an object relative to the sensor substrate, and drive the shield and the at least some sensor electrodes at a second frequency in a second mode different from the first mode to measure a force applied toward the sensor substrate.

摘要： An ambient light sensor includes a first stack of at least two photodiodes, wherein a cathode of one of the at least two photodiodes is electrically connected to an anode of another of the at least two photodiodes. The ALS further includes a bias source for providing a bias voltage to the first stack, and at least one switch electrically connected to the first stack. The at least one switch is operative to periodically apply the bias voltage to and remove the bias voltage from the first diode stack.

摘要： A display device includes a liquid crystal display having a plurality of pixels, each pixel having a corresponding pixel electrode. Each pixel also includes a volatile memory (VM) cell and a non-volatile memory (NVM) cell. The VM cell includes a VM cell input for receiving data to be stored in the VM cell and a VM cell output for outputting data stored in the VM cell. The NVM cell includes an NVM program input operatively coupled to the VM cell output, and an NVM data output for providing data stored in the first NVM cell to the pixel electrode. The display device also includes programming logic operatively coupled to each of the plurality of pixels, wherein the programming logic is configured to substantially simultaneously program each pixel's first NVM cell with data provided by each pixel's VM cell.
