What is an OLED TV? What are the advantages and disadvantages?

Compared with the current mainstream LCD display, OLED is characterized by self-luminous, high brightness, high luminous efficiency, high contrast, wide viewing Angle, thin and light, can be rolled and folded, easy to carry, fast response, good temperature characteristics, low voltage DC drive, low power consumption, flexible display, etc.boe 2023, plus OLED TV prices have gradually become less noble. OLED TVS are loved by consumers. "Do OLED TVS work?" ", "What are the advantages and disadvantages of OLED TV?

What is blue light hazard?

We all know that light in nature is made up of a spectrum of different colors, but different wavelengths are different colors to the eye, for example 600 to 700 nanometers, we see red light, at 500 to 600 nanometers, BOE displays we see yellow light, and blue light has a wavelength between 400 and 500 nanometers.

The shorter the wavelength, the higher the energy, and the stronger the penetration. The wavelength of blue light is relatively short, and now we are very concerned about the harm of blue light to the human eye.oled manufacturer At the moment, we are glued to screens everywhere. For daily use of electronic products. And this LED is the light screen, its main light source peak spectrum is this short-wave blue light. The longer it takes, the more damage it does to your eyes.

1. OLED TVS produce less blue light and are more friendly to the eyes

On the other hand, organic light-emitting diode technology can get rid of the LED backlight mode, and each pixel can emit its own light. As long as a voltage is applied to the electrode, the excitation layer can produce the desired color light.

In manufacturing, OLED uses organic materials, and materials that meet various color and process requirements can be obtained through organic synthesis research methods. Compared with inorganic material technology, not only does it not consume natural resources, but it can also improve the performance of OLED by synthesizing an organic material with better performance. The cost of the organic luminescent materials used greatly reduces the intensity of the blue spectrum. The wavelength of blue light produced by OLED TV is between 460-480 nm, according to the principle of physical experiment 'the shorter the wavelength, the higher the energy level', OLED TV has less impact on the energy produced by blue light than LCD TV, so the degree of harm to the human eye is less.

2. OLED TVS are thinner and have no flash screen

OLED TVS have the inherent advantages of being able to crush LCD in appearance, but they are also flexible and transparent. Thin and light is one of the core advantages of organic light-emitting diode self-luminous TV. With ultra-narrow bezels, OLED TVS look more like a perfect painting.

OLED LCD TVS generally use chessboard light control partitions, so almost all use low-frequency PWM dimming below 1000HZ, but instead of studying the PWM frequency and fluctuation depth of the TV, it is better to add money to directly buy DC dimming OLED TVS, worry and health. OLED TVS can achieve a thin appearance, mainly relying on the self-luminous characteristics of OLED, no backlight, each pixel can independently light.

3. OLED audio-visual integration technology

OLED panel screen sound technology is also the unique advantage of OLED self-lighting TV. The screen can be directly emitted by sound, and the sound can be directly transmitted from the screen when watching TV, so that the sound and the picture can be synchronized, this design can bring us a more immersive audio-visual experience, create a more vivid sound effect, and enjoy the movie-like experience at home.
