Abstract: Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time. This may allow double-row interlaced driving to reduce or eliminate image artifacts due to intra-frame pauses.

Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

Abstract: Systems, methods, and devices are provided to reduce or eliminate mura artifacts on electronic displays. For example, pixels may be programmed to a uniform gray level before all or a substantial number of gates of the pixels are activated. The voltages on some or all source lines that supply the pixels may be measured. A mura artifact may be seen when voltage differences on the source lines are present. As such, operational parameters of the electronic display may be adjusted to reduce or eliminate the mura artifact by reducing the voltage differences.

Abstract: A resistor having a known resistance is coupled in series with a device under test (DUT) having an unknown capacitance. An ac signal source having a known fundamental frequency is coupled to drive the resistor to thereby produce a first ac signal. A phase controllable signal generator produces a second ac signal. The first and second ac signals are fed to a mixer. An output of the mixer is low pass filtered. A peak detector monitors the low pass filtered output while sweeping the phase controllable signal generator, until a peak is detected. The set phase corresponding to the detected peak is then used to obtain an estimate of the unknown DUT capacitance. Other embodiments are also described and claimed.
