    摘要： A method of driving a display panel determines luminance coefficients of a plurality of light emitting blocks included in a light source module using a Gaussian function. A pixel luminance is determined using the luminance coefficient and dimming levels of the light emitting block. The pixel luminance is a luminance of light provided to each pixel of the display panel. Input data compensated using the pixel luminance to generate compensated data. The pixel luminance provided to the pixels is calculated by considering the luminance change due to the adjacent light emitting blocks. Thus, the luminance of the input data is accurately displayed.

    摘要： A method of driving a light source unit of a liquid crystal display panel according to an exemplary embodiment of the present disclosure includes the steps of calculating average and maximum values of image signals applied to the liquid crystal panel; calculating a representative value of the image signals using the average and maximum values; determining the luminance of the light source unit according to the representative value and driving the light source unit accordingly. The representative value may be calculated from Lrep−(1−β)×Lavg+β×Lmax, where Lrep is a representative value, Lavg is an average value, Lmax is the maximum value, and β is a value that decreases as a difference between the maximum and average image signal values increases, and has a range between 0 and 1.

    摘要： A driving method of a liquid crystal display is provided for improving an echo phenomenon in the screen and improving crosstalk in a 3D display device. The liquid crystal display includes a liquid crystal panel and a light source unit divided into a plurality of blocks and that irradiates light by a light source unit of the corresponding block being driven at a response time of liquid crystals of the liquid crystal panel. Data of a liquid crystal panel corresponding to the plurality of blocks is analyzed to determine an n-th block corresponding to a portion having the highest visibility. Driving periods of light source units of the n-th block, an (n−1)-th block, and an (n+1)-th block are synchronized.
