Method for driving a liquid crystal display device, an array substrate, method of manufacturing the array substrate and liquid crystal display device having the same

摘要

In a method for driving a liquid crystal display (LCD) device, an array substrate, a method of manufacturing the array substrate and the LCD device having the same, data signals are boosted by a first and a second boost signals up to a first and a second pixel voltages, respectively. The first and the second pixel voltages are applied to a transmissive electrode and a reflective electrode, respectively. As a result, the retardation of light passing through a liquid crystal layer on the transmissive electrode and the retardation of light of the liquid crystal layer on the reflective electrode may be controlled to be substantially equal to each other. Thus, the LCD device is driven in a transflective mode with a mono-cell gap so that the yield of the LCD device may be increased.

1. A method for driving a liquid crystal display (LCD) device, comprising:
outputting data signals according to image signals; boosting the data signals according to a first boost signal up to a first pixel voltage that is applied to a transmissive electrode to control first light passing through a liquid crystal layer on the transmissive electrode; and boosting the data signals according to a second boost signal up to a second pixel voltage that is applied to a reflective electrode to control the retardation of second light to be substantially equal to the retardation of the first light, the second light being incident into the liquid crystal layer on the reflective electrode and reflected from the reflective electrode, wherein the first boost signal is applied to a first boost line overlapping the reflective electrode, and wherein the second boost signal is applied to a second boost line overlapping the reflective electrode.
