Power saving: no stroboscopic vision protection, cold light source almost no heat, but need backlight to illuminate it. Led refers to semiconductor light-emitting devices. Using LED as backlight has many advantages compared with traditional backlight. For example, the essence of LED TV is liquid crystal TV, in other words, light-emitting diode. LED TV refers to liquid crystal TV with LED as backlight. It does not emit light. Liquid crystal refers to panel material. There is a misunderstanding
Power saving: no stroboscopic vision protection, cold light source almost no heat, but need backlight to illuminate it. Led means semiconductor light-emitting devices. Using LED as backlight has many advantages compared with traditional backlight. For example, the essence of LED TV is liquid crystal TV, in other words, light-emitting diodes. LED TV refers to liquid crystal TV with LED as backlight. It does not emit light. Liquid crystal refers to panel material. There is a misunderstanding. In short, the working principle of plasma is to bombard the phosphor with the "electromagnetic wave" generated by plasma recombination. In order to display the image. The plasma itself can emit light. The disadvantages of plasma TV are low resolution, high power consumption, high radiation and great influence on eyes. The working principle of liquid crystal TV is that the light transmittance of each liquid crystal molecular unit changes and the degree of refraction and reflection changes under different working voltage conditions. LCD does not emit light in this province, so a complete LCD screen must be backlit with the help of external light. In order to display the image. The advantages of LCD TV are: low radiation, high resolution, low energy consumption, significantly improved picture quality, thin body, easy to carry and so on. CCFL lamp is used as backlight. The biggest difference between LED TV and ordinary liquid crystal is that the backlight adopts LED light-emitting technology. The advantages of LED TV are: ultra-thin, lower energy consumption, better picture effect..
