The 120Hz frame inversion driving FHD LCD TV panels were fabricated without image degradations seen such as the luminance gradient and the horizontal crosstalk. The panels had the higher aperture ratio because of the wider electrode space between the pixel and common electrode than conventional S-IPS. The novel driving method of gate-low-voltage-swing was used to remove the luminance gradient and the new panel design of divided-common-feeding was adopted to suppress the horizontal crosstalk. These technologies were very successful to achieve the high aperture ratio in the S-IPS panel without increase of the panel cost.

A LCD is one of the high power consumption parts in portable devices. Improvement of the power consumption of the display device affects the increase in the duration of a battery in the portable device. One of the most methods to reduce the power consumption is the reduction of the pixel driving voltage. In this paper, we have proposed a novel voltage boost circuit in pixel structures which operates pixels by lower voltage than ordinary pixels. The proposed pixel structure makes the Data voltage up to 400% using by new four capacitors in series. As a result, it reduces the Data and VDD Voltage in a quarter. The CSt3 and Cst4 have been designed approximately three times bigger more than Clc and, we have confirmed that VDD of QoPV becomes 1/3 of VDD of Normal

We introduce the new pixel structure named 'Gate Space Share (GSS)'. The new structure consists of the two transistors together in order to reduce the area of the transistors. Reducing the space of the transistor is efficient to the transmittance of the LCDs especially for the high resolutions LCDs. We achieved 40% higher transmittance than the conventional structure of the 5.0 inch Full HD mobile display.
