Abstract:
A display device includes a display panel which displays an image based on input image data, a driving controller which generates a voltage control signal for adjusting a first power voltage applied to the display panel in an (N+M)-th frame based on a maximum grayscale value of the input image data of an N-th frame, where N is a positive integer, and M is a positive integer, and a power voltage generator which senses a power current applied to the display panel in the (N+M)-th frame, generates a second power voltage based on the voltage control signal, and controls a voltage level of the first power voltage based on the second power voltage and a current level of the power current.
Abstract:
A method of measuring light emission of a display panel and a method of compensating light emission of a display panel are disclosed. In one aspect the method of measuring light emission includes setting a location of a camera such that a imaging range area of the camera includes a first divided region among a plurality of divided regions, wherein the display panel is larger than the imaging range area of the camera and includes the divided regions, and wherein each of the divided regions is smaller than the imaging range area; first displaying a recognition pattern image on the first divided region. The method also includes shooting the first divided region by the camera so as to generate a recognition pattern shot; second displaying a single-color image on the first divided region.
