  • Publication number: 20240347643
    Abstract: An anti-ambipolar transistor in which a turn-on operation is performed at a specific gate voltage and a method of manufacturing the same are disclosed. A vertically stacked structure including a first semiconductor layer and a second semiconductor layer, which are disposed perpendicular to the surface of a substrate, is formed, and then a gate dielectric layer and a gate electrode, which completely surround the side of the vertically stacked structure, are formed. Through the vertical structure, an electric field is generated in a direction parallel to the substrate, and a drain-source current is applied in a direction perpendicular to the surface of the substrate. This ensures the integration of the transistor and efficient operation of the transistor.

  • Patent number: 9620053
    Abstract: The present invention relates to a technique for outputting threshold voltages by properly changing the threshold voltages such that the threshold voltages can protect low-voltage driving elements within an analog to digital converter when the threshold voltages of an OLED display panel are sensed and outputted to the analog to digital converter. The present invention comprises: a sampling capacitor which samples threshold voltages sensed and inputted from an organic light-emitting diode on a display panel; a charge-sharing capacitor which charges and shares the threshold voltages sampled from the sampling capacitor, or solely charges the threshold voltages to bypass the threshold voltages; and a sample-and-hold unit which has a plurality of switches for performing switching operations for the sampling operation of the sampling capacitor and the charging and the sharing of the charge-sharing capacitor, and scales the threshold voltages to threshold voltage areas having a certain value or less.
