  • Patent number: 11972083
    Abstract: Touch input devices are provided with the capability of sensing a capacitive load in a two-dimensional array while also being able to sense deflection or movement of the input device in multiple different locations under an input pad. A touch input device can beneficially be used in a remote control device and can be used with multiple input buttons or platforms overlaying multiple capacitive touch input regions on a capacitive touch sensor substrate. Movement and position of a capacitive load can be tracked and calculated via output signals from a set of electrodes or other capacitance sensors with irregular shapes, with inconsistent distances from the capacitive load, and which are positioned below variable materials and material compositions. Thus, tracking gestures and taps can be detected using the capacitance sensing devices, and deflection input can be detected using switches or other actuators situated under the capacitance sensing devices.

  • Patent number: 11967291
    Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated by a backlight unit that includes an array of light-emitting diodes (LEDs). The backlight unit may determine the type of content in the image data. The backlight unit may decide to prioritize either mitigating halo or mitigating clipping based on the type of content. The determination of the type of content in the image data may be used to determine the brightness values for the LEDs in the LED array. If the content is determined to be a first type of content, at least one given LED in the LED array may have a different brightness value than if the content is determined to be a second, different type of content. Classifying content in the image data may be useful in optimizing visible artifacts such as visible halo and clipping.

  • Patent number: 11928290
    Abstract: A scanning operation is performed to measure a first capacitance of a first sensor arrangement located proximate a capacitive sensor that corresponds to a function of a device. In response to the first capacitance not exceeding a first threshold, the scanning operation measures a second capacitance of the capacitive sensor to create an output used to control the function of the device. In response to the first capacitance exceeding the first threshold, operation of the scanning operation is modified to skip measuring of the second capacitance or to refrain from transmitting the output to a host of the device for controlling the function.
