Abstract: A super-steep switching device and an inverter device using the same are disclosed. The super-steep switching device includes a semiconductor channel disposed on a substrate and made of a semiconductor material having impact ionization characteristic; a source electrode and a drain electrode in contact with the semiconductor channel, wherein the source electrode and the drain electrode are disposed on the substrate and are spaced apart from each other; and a gate electrode disposed on the semiconductor channel so as to overlap only a portion of the semiconductor channel, wherein a top surface of the semiconductor channel includes a first area overlapping the gate electrode, and a second area non-overlapping the gate electrode, wherein a ratio of a length of the first area and a length of the second area is in a range of 1:0.1 to 0.4.

Abstract: A display apparatus having a mura compensation function includes a mura memory in which compensation data corresponding to coefficient values of a mura compensation equation is stored; and a mura compensation circuit configured to perform mura compensations on display data by using the mura compensation equation to which the compensation data has been applied, wherein the coefficient values are set so that the mura compensation equation has been fit to have a curve that satisfies known difference values of selected gray levels, a first estimation difference value of a first estimation gray level higher than the selected gray levels, and a second estimation difference value of a second estimation gray level lower than the selected gray levels, and wherein the compensation data comprises the coefficient values of the mura compensation equation in which all of the known difference values of the selected gray levels, the first estimation difference value, and the second estimation difference value have a differen

Abstract: A clearance adjusting device for a cable includes a wire having a first side connected to a drive mechanism and a second side connected to an operation mechanism to enable the drive mechanism to be operated in conjunction with the operation mechanism when the wire is moved in an other direction by operation of the operation mechanism, an elastic part having a first end portion connected to the wire and formed to be elastically compressible, and a clearance elimination mechanism fixed to a base, with the wire and the elastic part embedded therein while the wire passes therethrough, in a state where a second end portion of the elastic part is connected to and supported by the clearance elimination mechanism, such that the wire receives an elastic force provided in the other direction toward the operation mechanism by the elastic part.
