A manufacturing method of a display apparatus includes forming a display layer on a substrate; forming an opening by irradiating laser onto the display layer; and sealing the display layer formed on the substrate. The laser is irradiated according to a spiral movement path, and the opening is formed by irradiating the laser at least twice at the same location.

Manufacturing method of display apparatus using laser irradiation

A display apparatus includes a power generation unit, a control unit, a source driver, and a display panel. The control unit configured to receive image data, determine a reference grayscale value of the image data, and convert the image data to corrected data according to the reference grayscale value. The power generation unit configured to generate a first pixel driving voltage, a second pixel driving voltage corresponding to the reference grayscale value, and an analog driving voltage corresponding to the reference grayscale value. The source driver configured to generate grayscale voltages by using the analog driving voltage and output, as an image signal, a grayscale voltage corresponding to the corrected data from among the grayscale voltages. The display panel configured to receive the image signal and display an image corresponding to the image signal using the first pixel driving voltage and the second pixel driving voltage.
