Abstract: A display apparatus includes a display panel including a plurality of pixels, a gate driver which applies a bias gate signal to the pixels, a data driver which applies a data voltage to the pixels, an emission driver which applies an emission signal to the pixels, and a driving controller which controls the gate driver, the data driver, and the emission driver. The driving controller calculates a grayscale change region of input image data and a grayscale change level of the grayscale change region, determines a compensation region of the input image data based on the grayscale change region, determines a compensation grayscale voltage based on the grayscale change level, and compensates for the compensation region of the input image data based on the compensation grayscale voltage to generate output image data.

Abstract: A particle collecting device includes: a first collecting device to be located on a substrate transferred in a first direction, and extending in a second direction crossing the first direction; and a second collecting device adjacent to the first collecting device in the first direction, the second collecting device to be located on the substrate, and extending in the second direction. The first collecting device is to collect a first particle remaining on the substrate, and the second collecting device is to collect a second particle remaining on the substrate, the second particle including a material different from that of the first particle.

Abstract: A display device includes: a display panel which receives a driving voltage and an initialization voltage; a power manager which provides the driving voltage to the display panel; and a voltage generator which receives a feedback driving voltage from the display panel and generates the initialization voltage based on the feedback driving voltage. The feedback driving voltage is a voltage that is fed back to the voltage generator after the driving voltage supplied from the power manager passes through the display panel.

Abstract: A display device may include a display panel including a plurality of pixels, a data driver which applies data signals to the display panel, a scan driver including scan stages, which sequentially applies scan signals to the display panel, an emission driver including an emission stage which sequentially applies emission signals to the display panel, and a power supply voltage generator which generates a power supply voltage including high voltages and low voltages, and provides the high voltages having different voltage levels from each other or the low voltages having different voltage levels from each other to at least one selected from the scan stages and the emission stage. The power supply voltage generator generates a first high voltage, a first low voltage, a second high voltage lower than the first high voltage, and a second low voltage higher than the first low voltage based on an input voltage.
