Samsung Electronics Develops World's Largest (32'') LCD Panel Without a Color Filter.


SEOUL, South Korea -- Samsung Electronics Samsung Electronics (SEC, Hangul:삼성전자; KSE: 005930, KSE: 005935, LSE: SMSN, LSE: SMSD) is a South Korean multinational corporation and the world's largest and leading electronics and information technology company. , the leading manufacturer of LCD panels, announced development of the largest 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 ) panel that does not require the use of a color filter Color filter

An optical element that partially absorbs incident radiation, often called an absorption filter. The absorption is selective with respect to wavelength, or color, limiting the colors that are transmitted by limiting those that are absorbed.
. The new filter-less 32-inch TFT-LCD for TV applications will be unveiled at FPD (1) (Flat Panel Display) See LCD, plasma display, EL display, FED and flat panel display.

(2) (Field Programmable Device) An umbrella term for all chips that can be programmed by the customer including SPLDs, CPLDs and FPGAs. See PLD.
 (Flat Panel Display A thin display screen for computer and TV usage. The first flat panels appeared on laptop computers in the mid-1980s, and the LCD technology became the standard. Stand-alone LCD screens became available for desktop computers in the mid-1990s and exceeded sales of CRTs for the first time ) International 2005, which opens in Yokohama, Japan on October 19.

Samsung's new LCD panel employs a sequential color processing method that rapidly determines accurate color tones based on how long red, green and blue lights are emitted from the LED backlight back·light

. Pixels are not spatially arranged throughout the LCD, eliminating the need for a color filter. Conventional LCDs require both a cold cathode fluorescent (CCFL (Cold Cathode Fluorescent Lamp) Same as CCFT. ) backlight and a color filter to separate the white light emitted by the backlight into red, green and blue (RGB (Red Green Blue) The computer's native color space, which is the color system for capturing and displaying images. RGB was derived from our own perception of color because human eyes are sensitive to red, green and blue (see trichromaticity). ) sub-pixels.

Seongsik Shin, vice president of the Samsung Electronics LCD R&D Center said, "With the independent development of the color filter-less LCD, Samsung is able to produce the highest quality LCD panels at a lower cost. This further improves our market leadership position for high-definition LCD TVs of 32", 40" and 46" industry-standard screen sizes." He added, "The new technology will reduce the investment cost for new facilities, shorten production process times and increase production yields, boosting Samsung's performance and cost competitiveness in the LCD TV market."

To achieve the "sequential" display, Samsung Electronics' LCD R&D team used a novel RGB-emitting LED backlight. By combining the RGB light emissions from the backlight in precise sequences, the new LCD panel provides color saturation that is 110% of 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, while the aperture ratio is an exceptionally high 78% for television with brightness at 500nit.

Moreover, the new display panel consumes only 82 watts, just 60% of the power needed by a conventional 500nit CCFL backlight. In addition, its response time is 5ms or faster, making it ideally suited for multimedia and video applications where accurate color reproduction is required.

Samsung developed its first LED backlight unit (BLU BLU Blue

) in 2004 and completed low-power 40" and 46" versions using this BLU the same year. The breakthrough development of a 32" LCD without a color filter reasserts the company's leadership in the LCD industry.

Mass production of 32-inch panels without color filters is scheduled to begin in the second half of 2006.
