The difference with Laptop LCD screen LCD and Laptop LED screen

Jan. 4, 2011 - PRLog -- The difference with Laptop LCD screen LCD and Laptop LED screen

   LCD's full name is Liquid Crystal Display: it includes TFT, UFB, TFD, STN, and other types of LCD screen.
Notebook(Laptop) LCD common is TFT (seemingly my cellphone screen also is the shading # 76). TFT screens are thin-film transistors, English full name (ThinFilmTransistor), is an active matrix type LCD, in its back set special ray tube, can actively on the screen each independent pixel control, this also is the so-called active matrix TFT originated and so can improve yao should be big time, about 80 milliseconds, while the STN for 200 milliseconds. Also improved STN blink (water ripple) fuzzy phenomena, effectively improve the ability of the play, and dynamic picture STN, compared to TFT have excellent color saturation, reductive ability and higher contrast, the sun still see very clearly, but the disadvantage is more power consumption, and the cost is higher.
Leds are Emitting Light Emitting Diode Diode English abbreviations.
LED application can be divided into two types: one is LED single pipe application, including back light LED, infrared LED etc; The other is the LED display, at present, China in LED with international manufacturing base material still exist some difference, but the LED display is concerned, China's design and manufacturing technology level of basic and international synchronized.
The LED display is arranged by emitting diode composed of a display device. It USES low voltage scanning drive, has: less consumption, long service life, low cost, high brightness, low malfunction, perspective, visible distance etc. Characteristics.
LED display, compared with LCD display in LED luminance, power consumption and visual Angle and refresh rate, etc., are more advantages. Leds and LCD power than approximately 10:1, and higher refresh rate in LED video have made better performance, can provide wide amounted to 160 ° Angle of view, can display all kinds of characters, Numbers, color images and animations information, also can broadcast TV, video, VCD, DVD video signals, such as color of screen can also network with the broadcast. Organic LED display individual element reaction speed is LCD screen 1,000 times, in strong light also can look after not mistake, and adapt to the low 40s low temperatures. Using LED technology can create than LCD thinner, brighter and clear display, have broad application prospect.
Say simply, LCD and LED are two different display technology, LCD is composed of liquid crystal display, and LED by emitting diode is composed of screen. LED display, compared with LCD display in LED luminance, power consumption and visual Angle and refresh rate, etc., are more advantages.
OLED: Organic Light Emitting put, namely Organic Light Emitting displays, in the mobile phone LCD belongs to the new emerging species, known as the "fantasy Display". OLED display technology with traditional LCD display different ways, without a backlight, using a very thin organic material coating and glass substrates, when is energized, these organic materials will shine. And OLED display screen can do more quietly and thin, visible Angle, and can significantly greater saving electricity. However, although the future technology more excellent OLED will replace TFT LCD, but such as organic light emitting display technology still exist use short-lived, screen large-scale difficult wait for blemish.
