What’s the LED and LCD Monitor

Briefly , LCD and LED Monitor are two different display technologies , LCD is a liquid crystal display , the LED display is set by the LED light-emitting diodes. Compared with LCD Monitor, the LED of the LED Monitor have more advantages on the brightness, power consumption , viewing angle and refresh rate, etc. , . the consumption ratio of LED and LCD power is about 1:5 , and the higher refresh rate makes that the LED have better performance on the video , which can provide wide 160 ° viewing angle and can display a variety of text , numbers , color image and animation information , it can also play TV, video , VCD, DVD and other color video signal, the multiple Monitor can be networked broadcast. The response speed of the Individual elements of the organic LED display is 500 times more than that of the LCD screen, there is no trouble in watching in bright light , and adapt to the low temperature that is minus 40 degrees . Using LED technology , the displays that is thinner , brighter , clearer than the LCD can be made with a wide range of applications .


LCD is a liquid crystal display: it includes TFT, UFB, TFD, STN and other types of liquid crystal display.

Laptop LCD screen is a common TFT. TFT screen is a thin film transistor , which is an active matrix type of liquid crystal display , the special fluorescent tubes is set in its back , which can take the initiative on the screen to control each individual pixel , which is the origins of so-called active matrix TFT , this can significantly improve the response time , about 80 milliseconds,and the STN is 200 milliseconds ! It has also improved STN flashing ( ripple ) blurred , and effectively improves the ability to play moving images , and TFT has excellent color saturation、reducing capacity and higher contrast by comparison with the STN , it is very clearly under the sun , but the drawback is more power , and the cost is higher. LED ‘s resolution is generally low, the price is also dearer, because of the higher degree of integration .

The so-called LED display currently indeed is “LED -backlit LCD Monitor” on the market ; the LCD monitors that is currently popular are “CCFL backlit LCD display .” So both are liquid crystal displays , it is not the same as the backlight . Do not be misleading that the LED display is the next-generation of display technology , in fact, the latest technology is called OLED. As the environmental protection concept has been widely accepted now, some of the people emphasizing on the environment and the brand have began to focus on the “mercury ” concept of LED panel, no mercury LED panel will be more energy-efficient and environmentally friendly,

Personally think that damage to the eyes should be about the same, except that the new product more competitive !

Meanwhile, the LED lighting is widely applied as the generally lighting that is more closely with our daily lives, the illumination principle of the LED lighting is the use of light-emitting diodes, thanks to the semiconductor technology ,it can perfectly combine with design , medicine , agriculture, industry, electronics , and so many fields to bring us a new experience and a unique convenient.

The LED flood light such as  the portable LED flood light 10W and LED tube light are the most widely used as the representatives of the decorative lighting  and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while  low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection.
