One of the most common things to do every day is to stare at screens, from mobile phone screens to LED TVs , most people have become "sleepy" people. With all the time you spend on these screens every day, what do you know about them?

Friends who often pay attention to technology products should know that the popular LED TVs on the market are OLED TVs, QLED TVs and laser TVs. OLED TVs are closely related to the principle of optics, and the display on the TV screen is also different.

OLED TVs are made of organic compounds called organic light-emitting diodes, organic compounds can emit light alone, this is the display principle of OLED TVs, self-luminous, the OLED TV screen you see is composed of millions of Made of organic light-emitting diodes designed with high flexibility.

Due to the self-luminous display principle of LED TV , the flexibility of screen display is greatly improved. As long as all pixels are "extinguished", the screen can achieve a completely black effect.

Laser TV, everyone should be familiar with it when it comes to lasers. Medical X-rays, infrared laser spotlights, etc. all use laser technology. Lasers have a wide range of applications, but are often not used lightly because lasers can damage the eyes.

After some technical adjustments, laser TVs are not as irritating as laser pointers, but merchants are still worried that lasers will cause serious damage to the eyes, so there is a built-in reminder function for human eye protection mode, but this is only "treatment of symptoms, not the root cause" , eye protection actually produces minimal effect.

QLED smart high-definition TV is also a quantum dot TV, which is developed from the traditional LED TV . The white LED backlight is optimized to blue LED backlight, and a quantum dot enhancement film is also implanted for further imaging. In principle, the quantum dot enhancement film is equivalent to the filter of the QLED TV screen. The blue LED backlight passes through the quantum dot enhancement film to refine the light to the ideal color temperature and produce pure red, green and blue primary color light.

Its colors are pure, and in addition to making the colors very pure, in high-brightness pictures, the colors remain bright and saturated, and do not turn gray or white.
