With the rapid development of smart TVs, the screen display technology is also constantly developing. A large number of smart TV display technologies are appearing in front of people, and people are dazzled and unclear. Quantum dot TV is one of them! So what is Quantum Dot TV? What are their advantages and disadvantages? What is the difference between QD TV and OLED TV?
What is Quantum TV?
Quantum-dot TV is actually another name for QLED TV. The Chinese name is “quantum dot LEDâ€. This is a new technology that home appliance manufacturers expect to replace OLED in the future.
The principle of quantum dot television is to illuminate the red and green quantum dots with different diameters by irradiating the blue backlight to form three primary colors of red, green and blue (RGB), and then form an image through the imaging system such as the filter film and the drive system. To put it plainly, quantum dot TV is actually a kind of LED TV.
What are the advantages and disadvantages of Quantum TV?
Quantum TV advantages
The use of quantum dot material backlight is the most pure color backlight. Quantum dot TV uses the purest quantum dot light source as the backlight source, and it is a revolutionary implementation of the full color gamut display. So QD TV is called by the industry a better TV that replaces OLED.
Full color gamut display advantage; narrow band continuous spectrum, high color purity; 95% close to natural light, strong color reproduction, excellent color rendering; inorganic materials. Strong stability, long life, not easy to aging; precise color control; high efficiency, strong energy saving; beyond the OLED market prospects, the future can not use glass substrate material.
The disadvantages of quantum dot TV
The price of QD TV was fatal. In 2015, only TCL had released a 55-inch TV, and its price was as high as 1,299 yuan, while the 4K ultra-clear LED TV on the market was only about 5,000 yuan. The price difference between the two was two times. many!
Quantum-dot TVs also have a health problem because the quantum dots contain cadmium in their raw materials and there is a problem of cadmium volatilization. And cadmium is a recognized carcinogen, if the consequences of volatile can be disastrous.
What is the difference between QD TV and OLED TV?
Compared with OLED TVs, Quantum TV has four major advantages: wider color gamut display, more precise color control, longer life, and greater energy efficiency.
In terms of the screen rendering effect, it is known that the OLED display is a pure color obtained through a filter, and although the color through the filter is more pure, it may also be distorted. Quantum-dot TVs are stimulated by electricity or light from quantum dots and emit very pure, high-quality monochromatic light of various colors according to their diameters. At this point, quantum dot TVs are stronger than OLED displays, and distortion will not occur!
In terms of service life, since the inorganic materials used in quantum dot TVs are not easily oxidized, their imaging lifetime is 20,000 hours longer than that of OLEDs. And quantum dot TVs can operate at lower voltages, and energy consumption is minimized.
What is Quantum TV? What are the advantages and disadvantages of QLED smart TV? I believe that through the above introduction, you should have in-depth understanding! What QD TVs are currently on the market? Xiao Bian recommended TCL Q55H9700, Samsung SUHD 65KS7300, LG 65UF9500 are all quantum dot smart TV products, users can read the small series for the introduction of Quantum TV, and then to understand these several Quantum TV to choose!
