The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure (prism sheet) to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de ...
In 2008, LCD TV shipments were up 33 percent year-on-year compared to 2007 to 105 million units. [10] In 2009, LCD TV shipments raised to 146 million units (69% from the total of 211 million TV shipments). [11] In 2010, LCD TV shipments reached 187.9 million units (from an estimated total of 247 million TV shipments). [12] [13]
One of the earliest electronic displays is the cathode-ray tube (CRT), which was first demonstrated in 1897 and made commercial in 1922. [1] The CRT consists of an electron gun that forms images by firing electrons onto a phosphor-coated screen. The earliest CRTs were monochrome and were used primarily in oscilloscopes and black and white ...
James Lee Fergason [2] (January 12, 1934 – December 9, 2008) was an American inventor and business entrepreneur. A member of the National Inventors Hall of Fame, Fergason is best known for his work on an improved Liquid Crystal Display, or LCD.
By 1982, pocket LCD TVs based on LCD technology were developed in Japan. [17] The 2.1-inch Epson ET-10 [ 18 ] Epson Elf was the first color LCD pocket TV, released in 1984. [ 19 ] In 1988, a Sharp research team led by engineer T. Nagayasu demonstrated a 14-inch full-color LCD, [ 12 ] [ 20 ] which convinced the electronics industry that LCD ...
A generic LCD TV, with speakers on either side of the screen. Liquid-crystal-display televisions (LCD TV) are television sets that use liquid-crystal displays to produce images. LCD televisions are much thinner and lighter than CRTs of similar display size and are available in much larger sizes (e.g., 90-inch or 230-centimetre diagonal). When ...
The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de Vaan and Paulus ...
The True depth method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down, [2] and had a high response time (for this kind of transition, 1 ms is visually better than 5 ms).
