All walks of life in life, people and things are the same, there is no harm without comparison! Likewise, LED displays and LED TVs. As a mainstream display, it has received a lot of controversy in terms of size, power saving, and brightness. Next, Tuosheng Optoelectronics will introduce to you what is an LED display and what is an LED TV.

  What is LED backlight?

  We know that the liquid crystal material itself does not emit light, and the light source on the back of the liquid crystal panel is required to provide light support. This kind of light source has been dominated by CCFL cold light tubes in the past, and the light-emitting principle of CCFL cold light tubes is similar to the fluorescent tubes we use every day. However, CCFL cold light tubes also face problems such as uneven brightness, relatively high power consumption and mercury content. In contrast, LED backlights are better in terms of power consumption and material environmental protection, the brightness uniformity is relatively high, and the volume can be made thinner. Therefore, the prospect of LED backlight is very optimistic about the manufacturers.

  What is led display?

  Appropriate connections (both in series and in parallel) through LED chips and appropriate optical structures. It can form the light-emitting segment or light-emitting point of the light-emitting display screen. Such light-emitting segments or light-emitting points can be composed of digital tubes, symbol tubes, meter tubes, matrix tubes, level display tubes, and so on. Usually, the digital tube, the symbol tube and the meter tube are collectively called the stroke display screen, and the stroke display screen and the matrix tube are collectively called the character display screen.

  The LED display can display changing numbers, text, and graphic images. The reason why LED has been widely valued and developed rapidly is inseparable from its own advantages. It can be used not only in the indoor environment but also in the outdoor environment, and has the incomparable advantages of projectors, TV walls and LCD screens. Moreover, the LED display integrates microelectronic technology, computer technology and information processing. With its bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc., it has become the most advantageous public display media. The development prospect of LED is extremely broad, and it is currently developing in the direction of higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and full color.

  LED TV screen

  In fact, it is LCD TV (Liquid Crystal Display), which is a kind of LCD TV. The difference from traditional LCD TV is that it uses different backlight sources, which brings many differences in performance. As shown in the following table, LED TV adopts As a backlight source, light-emitting diodes have more advantages than traditional LCD TVs with CCFL backlights in terms of thickness, picture quality, lifespan, energy saving and environmental protection, and have become the recognized development direction of LCD TVs in the industry.

  Strictly speaking, LED TVs refer to TVs that completely use LEDs (light-emitting diodes) as display devices, which are generally used for low-precision displays or large outdoor screens. At present, the strict name of the LED TV usually referred to 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 theoretical life is longer, the production process is more environmentally friendly, and the liquid crystal display panel can be thinner.
