If we want to classify the screen material of cell phones, we can roughly distinguish two main schools of thought, namely LCD and OLED.


But when it comes to eye protection, LCD is better than OLED. If this is the case, why are cell phones nowadays willing to be equipped with OLED screens that hurt the eyes?


OLED screen display effect is delicate and realistic, the LCD screen is difficult to surpass.



OLED, also known as electromechanical laser display, organic light-emitting semiconductor, OLED display technology has self-illumination, wide viewing angle, and almost infinite contrast ratio. In other words, due to the self-illuminating qualities, OLED screens have greater color rendering power.


OLED screens are more popular among consumers due to their softer material and curved surface appearance. However, in industrial applications, curved screens can be problematic due to the viewing angle.



In today's era of "face value" as the strength, light with strong performance configuration, without "good-looking skin" also does not reach the best-seller. The OLED screen can raise the value of the phone up several grades, after all, this material itself is relatively soft, as long as through the appropriate processing, you can create a variety of unique appearance of the screen. The LCD screen is harder and more difficult to process, and based on this consideration, cell phone manufacturers prefer to use OLED screens.


In the case of the Huawei Mate 30 Pro, the phone is equipped with a curved OLED screen of nearly 90 degrees, which is visually stunning. Without this screen, I'm sure most consumers wouldn't buy it.


For the stroboscopic problem, manufacturers have added PWM dimming mode for OLED screens, but this way not only makes the screen "always-on" but also damages the eyesight. And with the improvement of OLED technology, the OLED screen phone can also have the whole DC dimming, so that in different light conditions, it is not because the phone screen is too harsh or too dark to see.


Conclusion: Whether technology can be adopted is entirely determined by consumers and the market.
