    Abstract: A display panel includes a plurality of pixels, data lines, gate lines, a gate driver and terminals. The plurality of pixels form a plurality of rows and columns. The plurality of data lines extend in a first direction parallel to the pixel columns. Each data line is connected to at least two adjacent pixels included in a single pixel row. The plurality of gate lines extend in a second direction parallel with the plurality of pixel rows. The gate lines each connect to at least one pixel included in a single pixel row. At least two gate lines are disposed between two adjacent pixel rows. The gate driver generates signals to drive the plurality of gate lines. The plurality of terminals receives the gate signals to transmit the gate signals to the plurality of gate lines. Some of the terminals connect with some gate lines having a cross-coupled structure.

    Abstract: A display apparatus includes a timing controller configured to convert input image data into a hue, saturation, brightness (HSV) color space to generate a saturation histogram, generate a saturation gain curve and a dimming value based on the saturation histogram, control saturation of an input image based on the saturation gain curve to generate a data signal, and control luminance of the input image based on the dimming value to generate a light source control signal. A data driver is configured to generate data voltages based on the data signal. display panel is configured to display an output image based on the data voltages. A light source is configured to provide light to the display panel based on the light source control signal.

    Abstract: A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.
