Disclosed are a liquid crystal display and a method of the liquid crystal display. The liquid crystal display includes a liquid crystal panel, a backlight unit that supplies light to the liquid crystal panel and has a plurality of light sources, and an image calibration unit that calculates a global dimming resultant value and a local dimming resultant value for an image data signal inputted to the liquid crystal panel, analyzes an average picture level for each block with respect to the image data signal, and determines a convex combination parameter based on the global dimming resultant value, the local dimming resultant value, and the average picture level to generate a calibration dimming value for the backlight unit and an image calibration value for the image data signal.

Liquid crystal display and method of driving the same

A liquid crystal display is disclosed. The liquid crystal display includes a liquid crystal display panel including a pixel array and touch sensors, a transparent conductive layer on one substrate of the liquid crystal display panel transmitting display light, a polarizing plate on the transparent conductive layer, a driving voltage supply circuit, and a signal transmitting unit electrically connecting the transparent conductive layer to the driving voltage supply circuit. A portion of the transparent conductive layer is connected to a ground level voltage source. The driving voltage supply circuit generates a driving voltage required to perform light sensing operations of the touch sensors during a touch period based on changes in an amount of surface charge of the transparent conductive layer depending on whether or not the polarizing plate is touched.
