LED is the English abbreviation of Light Emitting Diode.
compared with LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate. The power consumption ratio between LED and LCD is about 10:1, and the higher refresh rate enables LED to have better performance in video, providing a viewing angle as wide as 160 degrees, it can display all kinds of words, numbers, color images and animation information, and can also play color video signals such as TV, video, VCD, DVD, etc. Multiple display screens can also be broadcast online. The reaction speed of a single element of the organic LED display screen is 1000 times that of the LCD screen. It can also be looked after under strong light and adapt to the low temperature of minus 40 degrees. Using LED technology, thinner, brighter and clearer displays than LCD can be manufactured, with wide application prospects.
simply speaking, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, the LED is a display screen composed of light emitting diodes. Compared with LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate.
The laptop LCD screen takes the liquid crystal material as the basic component, fills the liquid crystal material between two parallel plates, and changes the internal molecular arrangement of the liquid crystal material through the voltage, in order to achieve the purpose of shading and light transmission to display images with different shades and random colors, and as long as a three-element color filter layer is added between the two plates, color images can be displayed.
TFT is commonly used in notebook LCD screens. TFT screen is a thin film transistor, full name in English ( ThinFilmTransistor) , Is an active matrix type liquid crystal display, set a special light tube on its back, which can actively control each independent pixel on the screen, which is also the origin of the so-called active matrix TFT, this can greatly improve the time, about 80 milliseconds, while STN is 200 milliseconds! It also improves STN flicker (Water ripple) The phenomenon of Blur effectively improves the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, restoring ability and higher contrast, and can still be seen very clearly in the sun, however, the disadvantage is that it consumes more electricity and has higher cost.
Shenzhen chuangxian Technology Co. , Ltd. is an LCD screen manufacturer, it is a joint venture high-tech enterprise integrating design, development, production, LCD screen, display module and LED backlight products. The company was established in 2009. Through continuous efforts, it first became a liquid crystal display enterprise with rapid development and vitality.
