    Abstract: A display device includes a display panel, a plurality of sensors, a signal control unit, and a backlight unit. A plurality of dimming regions is defined in the display panel. The signal control unit determines a plurality of representative luminance values corresponding to the plurality of dimming regions based on image data signals received from an external device and illuminance values of an external light measured by the plurality of sensors. The backlight unit provides lights having the representative luminance values to the display panel.

    CPC classification number: G06T5/009 ,  G06T3/403

    Abstract: In an image processing method that converts image data into output data by performing tone mapping, an edge of an image represented by the image data is determined, a first tone mapping operation is performed on first image data included in the image data, where the first image data represent a first portion of the image not including the edge, whether a gray level of second image data is within a predetermined gray range is determined, where the second image data represent a second portion of the image including the edge, a second tone mapping operation is performed on the second image data when the gray level of the second image data is within the gray range, and the first tone mapping operation is performed on the second image data when the gray level of the second image data is not within the gray range.

    Abstract: A display apparatus includes a frame memory storing an input image signal having first and second reference blank durations respectively corresponding to a first frame and a second frame. A blank controller circuit determines a second delay blank duration based on the first and second reference blank durations and a first delay blank duration, a signal delay part generates an output image signal having the first and second delay blank durations corresponding to the first frame and second frame, respectively, is based on the stored input image signal, and a display panel displays an image based on the output image signal. The display apparatus may reduce or prevent flicker caused by variations in driving frequency that may be variable on a per-frame basis. A blank duration of a frame is controller, or a frame may be inserted in a blank duration based on blank durations of adjacent frames.

    Abstract: A display device includes: a display panel; and a frequency controller which receives an image data signal and an input frequency information and outputs the image data signal and a timing control signal. The frequency controller includes: an image processor which receives the image data signal; a frame memory which stores the image data signal; an output frequency determining unit which receives the input frequency information and determines an output frequency based on a variation amount of the input frequency; and an image output unit which receives the image data signal from the image processor, receives an output frequency information from the output frequency determining unit, and outputs the image data signal and the timing control signal. When an input frequency varies, the output frequency determining unit determines the output frequency based on the following equations: K =  FREQ - P_FREQ M_FREQ  × SLOPE + OFFSET , and FREQ ′ = FREQ × K + P_FREQ × ( 1 - K ) .
