Samsung Electronics Develops World's First 3-inch LCD Screen of VGA Quality for Digital Still Cameras.SEOUL, South Korea -- Samsung Electronics Co., Ltd., the world's largest provider of thin-film transistor, liquid crystal display liquid crystal display (LCD) Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. (TFT-LCD TFT-LCD Thin Film Transistor - Liquid Crystal Display ) panels, announced today that it has developed the first three-inch LCD panel with VGA (Video Graphics Array) The display standard for the PC. All PC display adapters support VGA, and Windows machines boot up in "VGA mode" before switching to higher resolutions. (640 x 480 pixels) resolution that directly meets industry interface standards for digital still cameras. Executive Vice President Yun Jin-hyuk of Samsung Electronics said, "Our new LCD panel will make viewing of digital pictures distinctly more impressive on camera screens, personal multi-media players and other products requiring high-image resolution and low-power consumption." Digital camera makers use an interface known as ITU-R ITU-R ITU Radiocommunication Sector 601, an international standard for cathode ray tube See CRT. (hardware) cathode ray tube - (CRT) An electrical device for displaying images by exciting phosphor dots with a scanned electron beam. CRTs are found in computer VDUs and monitors, televisions and oscilloscopes. (CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. ) TVs that operates at 30Hz. This standard is incompatible with LCDs, which normally run at 60Hz. Manufacturers have had to reconcile the difference either by compressing the images or by manipulating the signal. However, such approaches will only work with LCDs having a resolution of qVGA(320 x 240 pixels) or less. Samsung's new LCD operates on 30Hz, allowing VGA images to be obtained from a digital camera without having to create another interface. The three-inch VGA LCD also incorporates a dot inversion scheme that lowers power consumption while substantially reducing the image flickering that has prevented such an approach in the past. Power consumption is further reduced because the 30Hz source driver requires less power than the 60Hz type, helping to better differentiate mobile display-based products. Samsung will exhibit its new device at IMID IMID Immunomodulatory Drug (Celgene) IMID Immune Mediated Inflammatory Disorders 2006, which opens in Daegu, Korea on August 23. Samsung will begin commercially producing the new VGA-resolution LCD panel in the first half of 2007.

Terminology ITU-R601: A video interface standard for TVs, established by the International Telecommunications Union See ITU. (body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. , which also is applied to digital cameras. Resolution Formats -- qqVGA: 160 pixels across by 128 rows high -- qCIF: 220 pixels across by 176 rows high -- qVGA: 320 pixels across by 240 rows high -- qSVGA: 400 pixels across by 300 rows high -- VGA: 640 pixels across by 480 rows high Dot Inversion: An inversion method for alleviating flicker in LCDs. Flicker: A visually distracting phenomenon created by alternating changes in the intensity of light emitted onscreen. Transmissive: A display that uses a backlight back·light n. A type of spotlight, used in photography, that illuminates a subject from behind. tr.v. back·light·ed or back·lit , back·light·ing, back·lights shining through a LCD panel to produce the image. Other types include semi-transmissive and reflective. Nit: An abbreviation abbreviation, in writing, arbitrary shortening of a word, usually by cutting off letters from the end, as in U.S. and Gen. (General). Contraction serves the same purpose but is understood strictly to be the shortening of a word by cutting out letters in the middle, for the measure of brightness properly called candela candela (kăndĕ`lə), in weights and measures: see candle. A unit of measurement of the intensity of light. Part of the SI system of measurement, one candela (cd) is the monochromatic radiation of 540THz with a radiant intensity per meter square (cd/m2). Color Saturation: A standard for measuring the intensity of color produced by a display. Color saturation is normally expressed as a ratio, with the NTSC (National TV Standards Committee) The committee that developed the television standards for the U.S, which are also used in Canada, Japan, South Korea and several Central and South American countries. Both the committee and the standard are called "NTSC. standard being 100%. TVs have a color saturation of 72% or higher, while the color saturation for small and mid-sized displays is about 50%. |
