  • Patent number: 8319716
    Abstract: A liquid crystal display (LCD) and method for driving the LCD using one or more polarity inversion methods is provided. In one embodiment, the invention relates to a method of driving an LCD comprising a liquid crystal panel partitioned by a plurality of gate lines and data lines and including a plurality of liquid crystal cells arranged in a matrix and auxiliary lines adjacent to and parallel to the gate lines, the auxiliary lines coupled with the plurality of liquid crystal cells, the method including supplying an auxiliary voltage that increases from a low level to a high level on a first pair of auxiliary lines adjacent to each other for a jth frame period, supplying an auxiliary voltage that decreases from a high level to a low level on a second pair of auxiliary lines adjacent to each other for the jth frame period, supplying the auxiliary voltages at levels opposite to the levels of the jth frame period on the first and second pairs of auxiliary lines in a (j+1)th frame period.

  • Patent number: 7480015
    Abstract: Disclosed is a method for manufacturing an array substrate of a translucent LCD capable of simultaneously forming source and drain metal layers as reflective electrodes while improving both the contact resistance in a transmissive region and the reflectivity properties in a reflective region. The source and drain metal layers have a triple-layered structure of Mo—Al—Mo and, the top Mo is selectively removed from the reflective region. As a result, the screen quality of products improves. In addition, about 5-6 masks are enough to manufacture an array substrate using half-tone exposure technology, in contrast to the prior art which uses 8-11 masks. As the number of masks and processes is reduced in this manner, the manufacturing cost decreases accordingly and the process is simplified.
