Abstract: A method for simulating sharpness of an image boundary including setting a boundary pattern including a boundary line between black and white, and a unit pattern including arrangement information of pixels; calculating simulation grayscale data for implementing the boundary pattern by using the unit pattern; and obtaining a sharpness index for the boundary line based on a contrast sensitivity function (CSF) and brightness data extracted from the simulation grayscale data.

Abstract: 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.
