  • Display device having data driver with reduced signal noise
    Patent number: 11670237
    Abstract: A display device includes a display unit, a scan driver, and a data driver. The display unit includes pixels coupled to scan lines, sensing scan lines, data lines, and sensing lines. The scan driver supplies a scan signal to the scan lines, and supplies a sensing scan signal to the sensing scan lines. The data driver supplies an image data voltage to the data lines, and detects sensing values of the pixels on a pixel column basis through the sensing lines during a sensing period. The data driver includes an analog-to-digital converter which converts the detected sensing values into digital data during the sensing period and outputs sensing data. The analog-to-digital converter pauses the detection of the sensing values during a first period of the sensing period.

  • MOSFET device with undulating channel
    Patent number: 11658214
    Abstract: A SiC MOSFET device with alternating p-well widths, including an undulating channel, is described. The undulating channel provides current paths of multiple widths, which enables optimization of on-resistance, transconductance, threshold voltage, and channel length. The multi-width p-well region further defines corresponding multi-width Junction FETs (JFETs). The multi-width JFETs enable improved response to a short-circuit event. A high breakdown voltage is obtained by distributing a high electric field in a JFET of a first width into a JFET of a second width.
