摘要： A noise measurement device for measuring noise of a test image displayed on a display device including a display panel and an input sensor configured to sense an external input, includes a luminance meter, a converter, and a determiner. The luminance meter is configured to: measure a luminance of the test image in a state in which the input sensor is turned on to generate first luminance measurement values; and measure a luminance of the test image in a state in which the input sensor is turned off to generate second luminance measurement values. The converter is configured to apply a contrast sensitivity function to luminance difference values between the first and second luminance measurement values to generate final conversion values. The determiner is configured to compare the final conversion values with a predetermined reference range to determine whether a defect exists in the test image.

摘要： A pixel and a display device including the pixel are disclosed. The pixel comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a first capacitor, and a light emitting element. The eighth transistor includes a gate electrode configured to receive a second data voltage, a first electrode connected to a fourth node, and a second electrode configured to receive an initialization voltage. The eighth transistor adjusts a voltage level of the first capacitor based on a difference between the voltage level of the first capacitor and a level of the second data voltage.
