In the past few years when we bought TV, we often had doubts about the difference between LCD and LED TV. In recent years, the concepts of LED TV, OLED TV and ULED TV have risen. What is the difference between LED, OLED, ULED TV? Friends who are sure to buy TV are very curious. The author then gave a brief analysis for everyone. Let people know about LED, OLED, ULED TV.
In fact, in addition to OLED TVs that can be seen on the market, others can be collectively referred to as LCD TVs and are non-active light-emitting technologies. LCD TVs can be divided into the above concepts based on the difference between panel technology and backlight technology. The different backlight sources directly determine the most intuitive experience of the color, brightness, contrast, etc. of the TV picture. Therefore, in the past two years, it has also become the technical focus of major TV manufacturers. The OLED TV is a technology that actively emits light from organic materials.
LCD TVs and LED backlights all use LED light-emitting diodes, which have the features of low power consumption, long service life, low cost, high brightness, low failures, large viewing angles, and long viewing distances. They are also the mainstream backlight sources. The multi-zone backlight technology can also achieve very helpful results, especially in the color gamut.
Although OLEDs and LEDs have only one letter difference, they actually describe two completely different things. The liquid crystal panel needs to emit light through the backlight source, the liquid crystal molecules cannot emit light by themselves, and the LED only refers to the backlight source. OLEDs are organic light emitting diodes that emit light spontaneously, so no backlight is required. Has the advantages of good anti-seismic performance, large viewing angle, high luminous efficiency, and ultra-thin. At present, OLED TVs are becoming popular and prices are increasingly close to the people.
ULED is a display quality technology introduced by Hisense, which is mainly for LCD TVs and electronic medical. It adopts multi-zone independent backlight control and Hiview art engine technology. ULED has significantly improved the traditional color display, contrast, and response speed compared to traditional LED display, and its image quality is close to that of OLED.
There is also a quantum dot TV. The English name is QLED. It is a TV that uses the quantum dot technology backlight and is also a kind of LCD TV. However, compared with LED TVs, QLED TVs use different backlight sources, resulting in a lot of differences in performance. Compared with conventional LED backlighting, traditional LCD TVs have more advantages in picture quality, energy saving and environmental protection, and have become new developments in LCD TVs in the industry. direction.

A motor with gearbox is a mechanical device utilized to increase the output torque or change the speed (RPM) of a motor. The motor's shaft is attached to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
