Popularization also has fatal flaws revealing the secret of LED-backlit displays

Nowadays, LED (Light Emitting Diode) is believed to be very familiar to many people. LED screens can be seen everywhere on the road. Nowadays, the application of LDE is very wide. The lighting devices such as TV, monitor, screen and projection are almost all using LED lights. Nowadays, the LCD industry has become the world of LED backlights. Everyone knows that the previous CCFL backlight has been replaced by LED backlight. Everyone knows that the more evolved the better, but is the LED backlight replaced by CCFL? And how many secrets are there?

Let's first take a look at the LED backlight. Many friends have heard of LED displays, but what is an LED display? The full name of the LED display should be an LED-backlit display. LEDs are not imaging devices in the consumer display industry, but in the large-screen field, imaging effects are now maturing, and they only play a role in lighting in consumer-grade displays.

The main reason for LED to replace CCFL: With the development of technology, the cost is gradually reduced, it replaces the original CCFL backlight, and the most important feature of LED is long life and stability. All of these outstanding features have replaced CCFL in one place.

LED backlight defects have a great impact on vision

Knowing so much, do you think that LED is very good and very suitable for current needs, low cost, good energy, and durable. But what we have to say today is that it is not very good. The main reason is that the damage to the eyes is very large. The blue light of a certain wavelength is the most harmful to the human eye, and the blue light component of the LED is very large, so the damage to the vision is more Big.

PWM is the meaning of pulse width modulation. Common display products are modulated by PWM. The current eye-protection display is to adjust the PWM, so the damage to the eyes has not been well cured. Nowadays, the eye-protection display is also exposed, from the health point of view, optimized with weak blue light to get the latest eye-protection display. After the lack of better eye protection methods in the near future, the Blu-ray display will also be well developed in the near future.

In today's society, the demand for health is getting higher and higher, especially the damage of the eyes is very important. The workload is now very large. It usually takes more than eight hours in a day, so the damage to the eyes is very large, so Everyone should pay attention to maintaining a healthy use when using the monitor. I believe that LED backlight will soon be reformed, which is also a must.
