An integrated circuit including: a plurality of physically unclonable function (PUF) cells each configured to generate a cell signal having a unique value; a selector configured to output a first signal obtained by not inverting a cell signal output by a PUF cell selected from the plurality of PUF cells and a second signal obtained by inverting the cell signal; and a key generator configured to generate a security key in response to the first signal or the second signal, wherein the selector includes a first conversion circuit configured to generate the first signal and a second conversion circuit having the same structure as the first conversion circuit and configured to generate the second signal.

Integrated circuit for security of a physically unclonable function and a device including the same

A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.

A display device includes a display panel, a plurality of readout circuits, and a deviation corrector. The display panel includes a plurality of pixels. The readout integrated circuits perform a readout operation of detected values including degradation information of the pixels, via readout lines connected to the pixels, when a degradation detecting operation is performed. The deviation corrector calculates weighted values to correct operating deviation of the readout integrated circuits based on an average of initial values. The deviation corrector generates corrected image data to correct input image data based on the weighted values. The initial values correspond to the detected values output from the readout integrated circuits when the display panel is in an initial state in which the pixels are non-degraded.
