Why do you still use OLED screens when your eyes hurt

Oied screen hurts the eyes, why do you still use Oied?

OLED screens hurt your eyes even more.

The main reason why OLED screens hurt the eyes is low-light flickering. In other words, the frequency of its strobe is relatively low. The higher the strobe rate of the screen, the less it will affect the health of the person. Otherwise, it will make people feel eye pain, visual fatigue and other problems.

Although the OLED screen hurts the eyes more than the LCD screen, it also has many advantages. So when we choose a screen, we must think about it carefully.

PrincipleThe OLED display principle is fundamentally different from LCD, mainly driven by an electric field, and organic semiconductor materials and light-emitting materials are emitted through supercarrier injection and recombination.

Essentially, the ITO glass transparent electrode is used as the device anode, and the metal electrode is used as the cathode, driven by the power supply, the electrons are transported from the cathode to the electron transport layer, and the holes are injected from the anode to the hole transport layer, and then migrate to the light-emitting layer. To put it simply, an OLED screen is composed of millions of "small light bulbs".

OLED screen is more harmful to the eyes, because OLED screen is a self-luminous screen composed of organic materials, it does not need the backlight plate of the traditional LCD screen, so it can be made thinner, when there is an electric current through the organic material, the screen will glow, so as to display the image.

Due to the incomplete fit between the OLED screen and the DC dimming, there will be uneven white display and color cast, so the OLED screen has to choose PWM low-frequency dimming. It is precisely because of this dimming that the damage to the eyes has also increased!

The LCD screen is different, covered with red, green and colorless filters, when the blue light passes through these three filters, it will form RGB three primary colors, so although the damage to the eyes is relatively small, but for a long time**and close-range**, it will also cause a lot of damage!

Therefore, as far as the current market development is concerned, OLED screens are a trend. Its unique characteristics and the accuracy of its display in terms of color are unmatched.

OLED vs LCD screen which hurts the eyes more.

AMOLED screens are more eye-catching than OLEDs due to higher blue light radiation, unstable brightness, flickering screens, oversaturated colors, and the risk of burning pixels.

1. Blue light radiation is higher.

AMOLED screens have higher blue light radiation compared to OLED screens. Blue light is a high-energy light that is able to penetrate the macular area of the eye and cause damage to the retina. OLED screens have relatively low blue light radiation.

2. The brightness is unstable.

The brightness of AMOLED screens is unstable, and this is because each pixel of AMOLED screens is made up of light-emitting diodes, and the luminous intensity of these LEDs is different, which will cause uneven brightness throughout the screen.

3. The screen flickers.

AMOLED screens are prone to flickering at low brightness, which is due to the fact that the pixels of AMOLED screens are composed of light-emitting diodes, and when the brightness is below a certain level, these LEDs will constantly switch on/off, resulting in flickering.

4. The color saturation is too high.

The color saturation of AMOLED screens is too high, which is due to the fact that each pixel of AMOLED screens is molded by light-emitting diodes, and the luminous intensity of these LEDs is too high, which will cause the colors to be oversaturated.

5. There is a risk of burning like spring stupid.

The pixels in an AMOLED screen are made up of light-emitting diodes, and these LEDs can burn due to prolonged use. Burning pixels can cause some visible marks to appear on the screen, which can affect the display of the screen.

In any case, LCD flagships can hurt your eyes because the strobe of LCD screens is much faster than that of OLED screens. Of course, from a professional point of view, which is more hurtful to the eyes, OLED screen or LCD screen, depends on the use scenario, not what mobile phone to look at.

In fact, this problem is the same as food additives, and to talk about harm regardless of dosage is to play hooligan. But we have to make a clear concept first, that is, whether it is an OLED screen or an LCD screen, it hurts the eyes! Because they all emit blue light.

The reason why there is a saying that OLED screens are not as good as LCD screens hurt the eyes is because the strobe frequency of OLED screens is relatively low, which is far inferior to LCD screens. Therefore, the blue light emitted by the LCD screen is indeed more than that of the OLED screen, that is, the "dose" is greater, and the harm is greater than that of the OLED screen, but in fact, it is not much different, and it depends on the use scenario.

Generally speaking, if you don't play with your phone with the lights off, the blue light damage of both OLED screens and LCD screens is about the same. Because the "dose" of blue light is determined by color temperature, if the color temperature is high, the screen emits more blue light, especially the LCD screen, because of its high strobe frequency, the blue light emitted by it is higher than that of the OLED screen. But the OLED screen can also emit a lot of blue light, if you really want to compare, then it is fifty steps and a hundred steps, all of which are very different.

The main difference between OLED screen and LCD screen is in the display effect, not in terms of hurting the eyes, because both screens are similar. If you really want to prevent the screen from hurting your eyes, then use less electronic products, and don't continue to use it after the lights are out, you can use it with a desk lamp.

In general, the LCD flagship machine hurts the eyes, because it doesn't hurt the eyes to look at the screen, not to look at the phone, no matter how good the LCD material is, it will hurt the eyes! Because there is no way for the screen not to emit blue light, and if the screen does not emit blue light, you can't see blue.

If the LCD flagship machine is used for a long time and is not used reasonably, it will also cause damage to our eyes and affect our vision.

The light on this screen is still very weak, so it won't hurt the eyes of children at all.

This first starts with a cavity group misunderstanding of strobe and refresh rate.

There is a certain connection but it is not close, and it can be basically ignored.

Suppose you have two bulbs of different colors, the refresh rate is the speed at which you change the bulbs.

Strobe is actually related to brightness, which can be understood as turning on and off the light bulb 30 times a second and turning on and off the light bulb 100 times a second, because they are more than your ability to process the slowness and rounding of your vision, so you won't feel that the light bulb is off.

I will only feel that the switch is darker and blind when it is switched 30 times, and the switch is pleasant when it is switched 100 times, but it is brighter.

However, the OLED screen is indeed more eye-catching than the LED, but with the 90 Hz OLED and the 144 Hz OLED, it is not necessarily who hurts the eyes more, mainly depending on the manufacturer's control of the strobe.

In order to pursue the screen to be made into a 6500K color temperature, the diode needs to emit stronger blue light if you want to make the screen look whiter. So do OLED screens hurt your eyes?

1. In terms of data, OLED screens are less harmful to the eyes than ordinary LCD screens.

2. The pixels of OLED materials can emit light on their own, and the organic light-emitting materials greatly reduce the intensity of the blue light spectrum, and blue light will cause visual fatigue, so the OLED screen should also be more eye-friendly and healthy than ordinary LCD screens.

OLED screens hurt the eyes, because OLED's PWM low-frequency dimming technology is particularly easy to make eyes tired; The blue light of the LCD screen causes lesions in the macula area. That is to say, both OLED screens and LCD screens will inevitably cause damage to people's eyesight.

PWM low-frequency dimming technology: Now mobile phones have the function of automatically adjusting the brightness, and a technology that automatically adjusts the brightness, especially the pure rock acting on the OLED screen is PWM low-frequency dimming, which is achieved by quickly switching the screen light source to control the brightness. And through PWM low-frequency dimming technology, our eyes will inadvertently make their eyes tired and accelerate the aging of vision.

Blue light: It is the light that the mobile phone screen emits when it is used, and the blue light can penetrate the eyes and reach the retina, thus settling the eyes.
