49.4L: Late-News Paper: Novel Pixel Structure for Quadrupling of Pixel Voltage

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
