OLED screens are not popular, do people only love LCD screens?
LCD is never a slave! Why do so many people hate phones with OLED screens? I don't know if you know that LCD is never a slave to this terrier? In fact, Ash was confused when he heard it at first, and after understanding, he knew that this sentence came from the mouth of some people who extremely hate OLED screen mobile phones. We all know that the current mobile phone screen material is basically divided into two types, one is LCD, and there is OLED display.
Now there is a very strange phenomenon, that is, as long as it is a high-end mobile phone, it basically uses OLED screens, and manufacturers will also take it as a major selling point to advertise. Obviously, from this level, OLED screens should be higher and better than LCD screens.
So the question is, in that case, why do so many people hate OLED screens and only love LCD screens? To figure this out, we need to understand the advantages and disadvantages of each of these two screens. LCD screen is also commonly known as hard screen, OLED screen is a higher price flexible screen. At the same time, the LCD itself does not have light-emitting characteristics, so there must be a backlight module to emit light. Due to its own characteristics, OLED screens can emit light autonomously without a backlight module.
The advantage of OLED screen compared with LCD screen is that its self-illumination feature has lower power consumption, which can make the mobile phone more power-saving to increase battery life. At the same time, because the OLED screen has the flexibility of ultra-thin and light, it can make the mobile phone thinner, and at the same time, the border is greatly reduced after folding, so that the mobile phone screen ratio is higher.
At the same time, OLED screen latency is lower, the color is more vivid, the viewing angle is wider, the contrast is higher, OLED is obviously more pleasing than LCD in terms of visual effects, OLED screen can achieve the purest black when displaying the black interface. From this point of view, OLED screens are almost all advantages, why do so many people pursue LCD screens that look outdated and old-fashioned?
That's because the shortcomings of OLED screens are also very obvious, Ash told you before, and one of the shortcomings that many people know is screen burning. Due to the self-luminous characteristics of OLED screens, displaying the same picture for a long time will cause the decay of luminescent pigments and form residues on the screen, then the mobile phone will have problems such as color casting, residual images, and reduced brightness.
Compared with the burning screen, OLED screen has one of the most serious defects, that is, low strobe, commonly known as splash screen. The strobe range of low health risks should be above 1250Hz, while the OLED screen strobe of the mobile phone is only 240Hz, this PWM dimming method adjusts the brightness by using the visual residue of the human eye to periodically change light and dark, so that the screen eyes will be very tired and become "spicy eyes" after looking at the screen for a long time.
In addition, in addition to Samsung's top OLED screen resolution reached 2K, the rest are 1080P, due to the special pixel P arrangement of OLED screen, resulting in 1080P resolution OLED screen display clarity is much worse than LCD, the classic "big fruit" screen is how it comes. Having said all this, Ash believes that everyone should also have a general understanding of why some people hate mobile phones with OLED screens so much, right?
