“…High-image-quality TFT-LCDs require a higher resolution [4], but this increases the number of data driver ICs and the product cost [5]- [7]. To reduce the number of data driver ICs while maintaining a high resolution, a double rate driving (DRD) method has been studied [8]- [11].…”

This paper proposes a new dot inversion data addressing technique to achieve a high image quality in thin film transistor liquid crystal displays (TFT-LCDs) using a double rate driving method. The proposed data addressing technique optimizes the charging sequence of sub-pixels to reduce the variation in pixel voltage caused by parasitic capacitance, while maintaining the low-power consumption of the data driver IC. To verify the performance of the proposed technique, three 17-inch full high definition fringe field switching mode TFT-LCD samples were fabricated and evaluated. The deviation of the green sub-pixel luminance using a test pattern (R0, G127, B255) is less than 2 gray levels, and the power consumption of the data driver IC when displaying a mosaic pattern is reduced to 3.6 W at a 13 V supply voltage. In addition, a new pixel structure with a high 59.4% aperture ratio reduces the power consumption of the backlight unit to 9.8 W, which is 16% less than a conventional design.Index Terms-Double rate driving (DRD), low-power consumption, image quality, data driver IC, TFT-LCD.

“…For example, the aperture ratio of UHD has approximately 65% of the Full HD aperture ratio. [2] Therefore, the studies of high transmittance have focused on the manufacturing technologies to reduce the width of gate and data lines and the material development to improve the mobility of transistors in order to shrink the area of the transistor and extend the aperture area of the pixel [3]. And many researchers also have studied for new types of LC modes and wall electrode LCDs for high transmittance and high resolution LCDs.…”

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.

To improve the transmittance of the liquid crystal display panel, a transparent ITO electrode is adopted to replace the metallic common electrode and serves as a storage capacitor in the PsVA mode display. The transmittance is improved by 15% compared with the common design. Since the ITO com electrode also blocks electric field from the metallic lines, a high contrast value over 6000 can be achieved though black matrix structure is not adopted. Such pixel design with extra large aperture ratio can be applied to future high resolution display devices.
