Abstract: An image sensor includes a sensor pixel. The sensor pixel includes a first transistor coupled between a first power source and a first node, where the first transistor is turned on in response to a first control signal, a light-sensing element coupled between the first node and a second power source, where the light-sensing element generates photocharges in response to incident light, a storage capacitor coupled in parallel to the light-sensing element between the first node and the second power source, and an amplifier including a plurality of transistors coupled in series between the first power source and an output line, where the amplifier outputs a sensing signal corresponding to a voltage of the first node in response to a first driving signal.

Abstract: A display device includes a display panel. The display panel includes a pixel including a light emitting element. A compensator calculates a current stress of the light emitting element based on input grayscale values sequentially provided for the pixel during a specific time and generates a first output grayscale value by compensating for a first input grayscale value provided at a current time point based on the current stress. A driver generates a data signal based on the first output grayscale value and supplies the data signal to the pixel. The compensator sets the first output grayscale value to be less than the first input grayscale value in case that the input grayscale values are greater than a reference grayscale value.
