Abstract: The present invention discloses a micro reflection-type liquid crystal display (LCD) using a step difference resulting from the existing array processing and a liquid crystal cell comprising liquid crystal molecules being aligned in parallel to perform optical compensation according to the difference between optical slow axes on orthogonal optical compensation films. In a compensation system comprising orthogonal polarizers, an equivalent retardation is acquired according to the differences between the slow axes on the optical compensation films and the alignment orientation of the liquid crystal molecules when the liquid crystal cell is driven or not to determine the optimal dark/bright state. Moreover, the optimal dark state can be achieved at the same driving voltage under both the reflection mode and the transmission mode. Thereby, the present invention achieves improved image contrast and reflectivity without additional processing steps.

Abstract: A transflective LCD having a dual common-electrode structure has a front substrate, a liquid crystal layer and a rear substrate. The front substrate has multiple first and second common electrodes respectively connected to a first and a second contact pads. The first and second contact pads are respectively connected to two voltage sources to obtain different voltage. The rear substrate has multiple pixels, each has a reflective region and a transmission region. The reflective region is aligned to the first common electrode and the transmission region is aligned to the second common electrode. Since the voltages to the first and second common electrodes are different, the voltages of two liquid crystal capacitors corresponding to the reflective and transmission regions are also different. Therefore, the V-T curves of one pixel are adjustable to be close to each other by supplying different voltages to the first and second common electrodes.

Abstract: A transflective LCD having a dual common-electrode structure has a front substrate, a liquid crystal layer and a rear substrate. The front substrate has multiple first and second common electrodes respectively connected to a first and a second contact pads. The first and second contact pads are respectively connected to two voltage sources to obtain different voltage. The rear substrate has multiple pixels, each has a reflective region and a transmission region. The reflective region is aligned to the first common electrode and the transmission region is aligned to the second common electrode. Since the voltages to the first and second common electrodes are different, the voltages of two liquid crystal capacitors corresponding to the reflective and transmission regions are also different. Therefore, the V-T curves of one pixel are adjustable to be close to each other by supplying different voltages to the first and second common electrodes.
