  • Patent number: 9432044
    Abstract: A multi-segment capacitive successive approximation analog to digital converter (SAR ADC) is calibrated by determining an error voltage for each of a plurality of most significant bit (MSB) capacitors in a first segment using a calibration DAC. The first segment is connected to the second segment by an attenuation capacitor. Each of the error voltages corresponding to the MSB capacitors is digitized to form a set of digitized error voltages. An error voltage for each of a plurality of less significant bit (LSB) capacitors in at least the second segment is calculated by summing the set of digitized error voltages to form a sum of error voltages (sum(e)) and assigning a percentage of sum(e) as the error voltage for each of the LSB capacitors, such that a mismatch in the attenuation capacitor is mitigated.

  • Patent number: 9419355
    Abstract: A display module includes a display panel, a driver integrated circuit, a flexible printed circuit (FPC), a drive signal wiring and a power wiring. The driver integrated circuit applies power and a drive signal to the display panel. The FPC is electrically connected between the driver integrated circuit and a PCB. The drive signal wiring is extended from the FPC to the display panel through the driver integrated circuit and may transmit the drive signal to the display panel. The power wiring transmits the power to the display panel. The power wiring includes a first power line extended from the FPC to the driver integrated circuit, and a second power line extended from the first power line to the display panel. The second power line does not intersect the drive signal wiring, and a ground slit is not generated.
