The method requires three times the number of gate drivers, which in turn are integrated in α-Si silicon onto the glass substrate.This new method has been successfully tested and verified on a 12.1-inch WXGA TFT-LCD panel using only two data driver IC's.

Abstract— Thin‐film‐transistor liquid‐crystal displays (TFT‐LCDs) have the largest market share of all digital flat‐panel displays. An LCD backlighting system employing a three‐color red‐green‐blue light‐emitting diode (RGB‐LED) array is very attractive, considering its wide color gamut, tunable white point, high dimming ratio, long lifetime, and environmental compatibility. But the high‐intensity LED has problems with thermal stability and degradation of brightness over time. Color and white luminance levels are not stable over a wide range of temperature due to inherent long‐term aging characteristics. In order to minimize color point and brightness differences over time, optical feedback control is the key technology for any LED‐backlight system. In this paper, the feasibility of an optical color‐sensing feedback system for an LED backlight by integrating the amorphous‐silicon (a‐Si) color sensor onto the LCD panel will be presented. To minimize the photoconductivity degradation of a‐Si, a new laser exposure treatment has been applied. The integrated color‐sensor optical‐feedback‐controlled LED‐backlight system minimized the color variation to less than 0.008 Δu'v' (CIE1976) compared to 0.025 for an open‐loop system over the temperature range of 42–76°C.

Instrumented facet fusion alone is a simple, safe, and effective surgical option for the treatment of patients with single-level disorders, especially patients with degenerative spondylolisthesis.

A touch screen panel (TSP) embedded 12.1-inch LCD employing a standard a-Si:H TFT-LCD process has been successfully developed. Compared with conventional touch screen panels, which use additional components to detect touch events, the new TSP exhibits a clearer image and improved touch feeling, as well as enabling the LCD module to provide the sensing data through the driver ICs with an integrated readout function. Our new internal digital switching TSP can be fabricated with low cost because it does not require any additional components compared to a standard a-S:H TFT LCD.
