Abstract:
A display apparatus includes a display panel, a timing controller, and a data driver. The display panel includes subpixels for displaying images. The timing controller accumulates a count value when a same grayscale value repeats for one of the subpixels, determines a boundary portion of the image based on the accumulated count value, and generates a data signal to compensate the boundary portion. The data driver converts the data signal to a data voltage for the display panel.
Abstract:
A touch display device includes a touch sensor, a visual accelerator, and a display. The touch sensor senses a touch. The visual accelerator visualizes the touch. The display displays information corresponding to the visualized touch. When the touch is outside a visual acceleration area, the visual accelerator does not process the touch. When the touch is in the visual acceleration area, the visual accelerator visualizes the touch on the display.
