Abstract: A display device is disclosed. A display panel includes a plurality of subpixels of a plurality of colors arranged in a matrix form, and a plurality of gate lines and data lines respectively connected to the subpixels. A data driver is configured to supply data voltages to the subpixels through a plurality of source channels and the data lines. A switch circuit is configured to connect one of the source channels selectively to one of the data lines during a first scan period in one horizontal period and to a different one of the data lines during a second scan period in the one horizontal period. The data driver is configured to supply data voltages of one color to the one of the source channels during both the first scan period and the second scan period in the one horizontal period.

Abstract: A light valve panel and a liquid crystal display using the same are discussed. The light valve panel according to an embodiment includes a transparent electrode layer having a plurality of blocks supplied with a voltage through data input lines. The transparent electrode layer has a low resistance or has a high resistance. When a transparent electrode layer has low resistance, each block is divided into a plurality of segment electrodes connected through a resistance pattern. A voltage is distributed to the plurality of segment electrodes of each block based on the resistance pattern. When a transparent electrode layer has high resistance, the voltage distribution in each block is based on a resistance difference that varies based on a distance between voltage feeding positions.
