In all walks of life, people and things are the same, without contrast, there is no harm! Also, LED screens and LED TVS. As a mainstream display, there is a lot of controversy over size and power saving and brightness. Then I'll show you what LED displays are LED TVS.
What is LED backlight?
We know that the liquid crystal material itself is not luminous, it needs the light source of the back of the LCD panel to provide light support. This kind of hair light source in the past has been the CCFL cold light tube mainly, the luminescence principle of CCFL cold light tube is similar to our daily use of the daylight lamp tube. However, the CCFL cold light bulbs also face problems such as uneven brightness, relatively high power consumption and the inclusion of mercury elements. In contrast, LED backlight does better in power consumption and material environment, and the brightness uniformity is relatively high and the volume can be made thinner. So the prospect of LED backlighting is highly favored by the manufacturers.
What are led displays?
Proper connection of led chips (including series and parallel) and proper optical structures. The luminescent or luminous spots that make up the glowing screen. The luminescent or luminescent points can be composed of a digital tube, a symbol tube, a meter tube, a matrix tube, a flat screen tube, etc. The digital tube, the symbol tube and the meter pipe are commonly referred to as the strokes, while the strokes and matrix are collectively referred to as character displays.
LED displays can display changing Numbers, text, and graphic images. The fact that LED has been widely valued and developed rapidly is inseparable from its own advantages. Not only can be used in indoor environment also can be used in outdoor environment, have the advantage that projector, TV wall, LCD screen cannot compare. And LED display set microelectronics technology, computer technology and information processing in one, with its colorful, wide dynamic range, high brightness, long life, stable and reliable work, become the most advantage of the public display media. The development prospect of LED is very broad, and it is developing in the direction of higher brightness, higher weather resistance, higher luminescence density, higher luminous uniformity, reliability and whole color.
The LED screen
Is actually the LCD TV (Liquid Crystal Display), namely a kind of Liquid Crystal TV, it is different from traditional LCD TV is mainly adopted different back light, resulting in a number of different performance, as shown in the following table, using light-emitting diodes as back light LED TV, than the traditional CCFL backlight LCD TV in thickness, picture quality, life, more advantage on energy conservation and environmental protection, has become the industry recognized LCD TV development direction.
In strict sense, LED TV refers to a television that is fully equipped with LED (LED) as a display device, usually used for low accuracy display or large outdoor screen. Currently, the strict name of LED TV in the home appliance industry in mainland China is "LED backlight LCD TV", which refers to the LCD TV with LED as the backlight source, which is still a kind of LCD. It replaces the traditional fluorescent tube with LED light source, the picture is better, the theory life is longer, the production process is more environmentally friendly, and can make the LCD panel thinner.
