Liquid Crystal Display Technology

Sharp-the expert on liquid crystal-put 30 years of its accumulated liquid crystal technologies into the Kameyama Plant.

Sharp has been pioneering the possibilities of LCD technologies

About 30 years ago, Sharp released the COS (Calculator on Substrate), a pocket-sized electronic calculator that, for the first time in the world, featured an LCD as its display. Since then, Sharp has been solving difficult problems and pioneering the new possibilities of LCD technologies, such as colorization, wider viewing angles, faster response time, and larger sizes. In other words, Sharp has been leading the evolution of liquid crystal display.

・Sharp’s 30-year history of liquid crystal development

1973: Electronic calculator Succeeded in putting electronic calculators to practical use. Developed the world’s first electronic calculator incorporating an LCD. 1987: 3-inch LCD color TV Created vivid images with the highest pixel number in the industry. 1992: LCD ViewCam Installed a 4-inch color LCD monitor in a video camera, allowing images to be viewed right after shooting them.
1993: Personal digital assistant Produced a personal digital assistant (PDA) capable of managing basic business items such as address books and schedules pioneered the PDA market 2001: AQUOS LCD TV AQUOS debuted as the perfect TV for homes of the 21st century. Equipped with Advanced Super View LCD, AQUOS achieved high resolution with the highest brightness in the industry. 2005: AQUOS full-HD LCD TV These AQUOS featured further-evolved technologies such as newly developed full-HD panels. Contrast, response time, viewing angle, and reproduction of colors were dramatically improved.

Proprietary Sharp liquid crystal technology, Advanced Super View LCD

Advanced Super View LCD is the name of proprietary Sharp high-resolution, image-displaying technology. High contrast, a wide viewing angle, and fast response time were achieved by overcoming the conventional shortcomings of liquid crystals and by introducing a variety of technologies that allow, for example, the manipulation of liquid crystal alignment.

High contrast
Contrast is the difference in light intensity between the brightest white and the darkest black. Advanced Super View LCD uses the normally black method, which appears black because it does not let light pass through when the voltage is off. Light leakage in this state is almost nil, resulting in Advanced Super View LCD's high contrast.
   
Wide viewing angle
Because liquid crystals face all directions when the voltage is on, images on screen are equally clear and bright from all angles, offering a wide viewing angle.
   
Fast response
By moving liquid crystal molecules rapidly, Advanced Super View LCD can display fast-moving images, such as sports scenes, with no image retention.

Since first installed on AQUOS in 2001, Advanced Super View LCD has been evolving with the product. Sharp will keep pursuing higher image quality for AQUOS by promoting the evolution of Advanced Super View LCD.
