The two most common display technologies used in smartphones are LCD and OLED, each of which has advantages and disadvantages.
As a result, users of both technologies compete against each other. oled panels manufacturer But we all know that LCD and OLED are good or bad.
There are certain aspects of organic light-emitting diodes that the "liquid crystal Party" cannot accept in comparison with liquid crystals, flexible OLED so they can stick to their creed.
The "eye injury" that we often mention is actually a low-frequency flash problem of OLED screens under PWM dimming.
There is a reason for this, of course.
Despite this, strobe lights with low impact on human health should be above 1250Hz; china oled Basically, they won't affect human health, at least should be above 3000Hz.
The term refers to LEDs rather than OLEDs, but because both are LEDs and use PWM dimming, it does have a certain meaning.
Stroboscopes used in organic light-emitting diode mobile phones using PWM dimming are currently around 200Hz~250Hz,
The frequency increases as the brightness of the screen decreases.
Therefore, it is not unreasonable to say LCD looks more comfortable for a long time than OLED, since the low-frequency flash of OLED is indeed easier to develop in dark environments than the stroboscopic LCD above 1000Hz, which is more likely to fatigue the eyes.
We cannot feel the stroboscopic changes with the naked eye when using an OLED phone, but if you are more sensitive to stroboscopic, you can still feel the difference between LCD and organic light-emitting diodes.
Organic light-emitting diodes suffer from screen branding.
The OLED also has a fatal defect problem, whereas the previous stroboscopic was easy to brand.
The self-luminous nature of OLED pixels means that no matter where you switch, you'll be able to vaguely see the app's search bar, icons, and even text content after displaying specific content for a long time.
Because 99.9% of organic light emitting diode (OLED) screens have an imprint, it is the fatal flaw of organic light emitting diode (OLED) screens. In fact, it is not due to poor OLED quality, but due to a congenital short-life defect that occurs in the OLED itself, which can last up to 2 years, or as little as 6 months, so the screen needs to be replaced.
LCD is not easy to develop branding, but that doesn't mean LCD won't appear in this situation, as I have used it because of the screen aging problem and residual shadow. It is worth pointing out, however, that LCD has a smaller branding phenomenon than OLED.
