Therefore, although most of China's flagship mobile phones are based on OLED screens, there are still many people who still insist on LCD screens.

LCD and OLED screens are the two most used display technologies in smartphones, boe 2023,BOE displays,oled manufacturer and they are two different products, each with advantages and disadvantages.

But because of this, users of the two technologies compete with each other. But in fact we all know that LCD and OLED in the end is good or bad, so far no one has given the best answer.

The reason why the "liquid crystal Party" can stick to its creed is not because they are old-fashioned, but because there are certain aspects of organic light-emitting diodes that they cannot accept compared with liquid crystals.

For example, the "eye injury" that is often mentioned by us is actually the low-frequency flash problem of the OLED screen under PWM dimming.

Of course, this is not without reason.

Literature pointed out that long-term viewing of LED lights will cause visual fatigue, migraine and other diseases for users. However, the strobe light with low impact on human health should be above 1250Hz; Basically will not affect human health, at least should be above 3000Hz.

Although strictly speaking, refers to the LED light source rather than OLED, but because the two belong to LED and use PWM dimming, it has a certain reference value.

At present, the stroboscope of the organic light-emitting diode mobile phone using PWM dimming technology is about 200Hz~250Hz,

As the brightness of the screen decreases, so does the frequency.

So it is not unreasonable for someone to say that LCD looks more comfortable than OLED for a long time, because in the dark light environment, the low-frequency flash of OLED is indeed easier to develop than the stroboscopic LCD above 1000Hz, which is more likely to affect eye fatigue.

Although we can't feel the stroboscopic changes with the naked eye, when using an OLED phone, we don't even know there is stroboscopic. But if you are more sensitive to stroboscopic, you can still feel the difference between LCD and organic light-emitting diodes.

Screen branding is the Achilles heel of organic light-emitting diodes.

Compared to our previous stroboscopic, OLED also has a fatal defect problem is an easy to develop branding.

Due to the self-luminous nature of OLED pixels, after displaying specific content for a long time, you'll find that no matter where you switch, you'll be able to vaguely see the app's search bar, ICONS, and even text content.

The fatal flaw of organic light emitting diode (OLED) is the screen imprint, because 99.9% of organic light emitting diode (OLED) screens have imprint. But this is not because the OLED quality is poor, but because the OLED itself has a congenital short-life defect, according to personal habits, up to 2 years, as short as 6 months, the only solution is to replace the screen.

Of course, although LCD is not easy to develop branding, but it does not mean that LCD will definitely not appear in this situation, I have used is because of the screen aging problem and residual shadow. However, compared with OLED, the branding phenomenon of LCD can be said to be small.
