Abstract: A laser cutting apparatus includes a laser module, a vibration module, a motor module, a reflective module, and a concentrating module. The vibration module includes a lens module, and a piezoelectric module coupled to the lens module and configured to repeatedly expand and contract. The motor module is configured to move the vibration module in by transmitting power to the vibration module. The reflective module is configured to reflect the laser beam in such a way that a traveling direction of the laser beam is changed. The concentrating module is configured to concentrate the laser beam in such a way that energy of the laser beam reflected by the reflective surface is concentrated at a focal point.

Abstract: A display device includes a controller, a panel driver, and a voltage generator. The controller generates a first control signal and generates image data and a second control signal in response to first and second image signals. The panel driver generates a driving signal in response to the image data and the first control signal to drive a display panel. The voltage generator generates a driving voltage to drive the display panel and changes a voltage level of the driving voltage in response to the second control signal. The first image signal corresponds to a second frame located before a third frame in which the driving voltage is changed. The second image signal corresponds to a first frame located before the second frame. The controller generates image data corresponding to the second frame in response to the first image signal and the second image signal.

Abstract: A pixel circuit includes a light emitting element including a first electrode and a second electrode, a first switching element including a control electrode, a second switching element, a third switching element, a sensing resistor and a fourth switching element. The first switching element applies a first power voltage to the first electrode of the light emitting element. The second switching element applies a data voltage to the control electrode of the first switching element. The third switching element senses a signal of the first electrode of the light emitting element. The sensing resistor includes a first end connected to the second electrode of the light emitting element and a second end which receives a second power voltage. The fourth switching element senses a signal of the second electrode of the light emitting element.
