Abstract: Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.

Abstract: A method and apparatus are explained for performing white point color adjustment for a display device. This can be done by obtaining a value of an ambient light sensor, determining whether to make a white point adjustment, and, for a dynamic white point adjustment, using the value from the ambient light sensor in performing white point adjustment toward target color coordinates. A white point might be set equal to the target color coordinates, but might also remain unchanged for small ambient light changes or ambient light outside a region of interest. The white point might be changed to the target color coordinates in multiple steps. Various parameters might be used that can be varied to vary behavior of the white point adjustment.

Abstract: Techniques for removing display-based corrupting components from a capacitive sensing signal are provided. A routing carrying display related signals (e.g., a source signal for sub-pixel updating) may induce corrupting current into a routing for carrying capacitive sensing signals. This corrupting current may reduce the ability to determine presence of an input object via the sensing signal. Therefore, the corrupting signal is effectively removed by driving the display elements with a dot inversion technique and by performing capacitive sensing for a sensor electrode during a time in which an even number of display rows are driven for display updates. Dot inversion causes the corrupting current to alternate polarity. Thus, driving sensor electrodes in a period of time in which an even number of rows is driven means that an equal number of positive and negative polarity corrupting currents are induced into the sensing signal.
