Many people have been asking the question of OLED in the end whether we can buy, I can only say, you can accept its "shortcomings", you can buy!!!! boe 2023 However, there is only one concept on the board for the shortcomings of OLED, that is, "brand", in fact, when you ask whether this mobile phone can be bought, I hope they can use the word "brand" to persuade them, because of other shortcomings, it is very troublesome to explain, and it may become a war
So this is an article that lists all the pros and cons of OLED that I know of and would certainly be welcome if there were more professional additions
Advantages of OLED:
1. High color saturation, bright color, high contrast.
2. Black doesn't glow to save electricity (it's actually all black)
3. Because of the self-lighting characteristics, it can be made thinner and there is no backlight,BOE displays which is conducive to saving the space of the phone.
4. Because it is thin and light, we can fold and bend
Drawbacks of OLED:
1. Branding
2. Color decline
3. Short life cycle (supplier's biggest advantage)
4. It consumes a lot of electricity when it emits white light.
5. PWM low frequency dimming can cause great damage to the eyes
Well, the advantages and disadvantages are listed, the following to begin to explain these in detail, oled manufacturer the advantages of the part can be needless to say, the advantages of some media are touted to the end, there is nothing to talk about, so the detailed part of the students will only talk about the shortcomings of the part
Why do you think the media rarely talk about these shortcomings? It's very simple, it's a matter of interest, in a capitalist society, the business is to find a way to use the information asymmetry to make money, and try to find a way to make the consumer a fool (otherwise how can OPPO be hot?) The marketing budget is necessary for us to make a lot of money, the media said: Anyway, I just don't say, I'm not lying (counting money).
1. Branding:
When it comes to rotting, skip it
2. Color decay:
Because OLED is self-luminous, it will have a decay problem just like the light bulb, self-luminous is RGB three colors, green is the most problem, red and blue luminous efficiency is not good, and then the biggest problem in blue, blue aging speed is very fast, and in order to solve this problem, the material industry suggested that OLED manufacturers use RGBb (Figure 1), Blue uses a light and a dark to share the work with each other, so you can look at a lot of panels and various fancy RGB designs that's why (but even then the life of blue is still not high)
Then the white screen below shows the situation. The blue side represents the manufacturer to make the blue bigger, while the green side is the manufacturer's design on the circuit, so that green provides a higher proportion in the case of high brightness, because the red and blue light efficiency is not good, if the two ratio and green are as high as will be very power-consuming, blue is power-consuming, will shorten the life
So just like the Blue Age, the screen will turn green and the other two will fade, but not as fast as the blue
(Figure 1)
Various screens display white status.
3. Short life:
This is unavoidable, can only rely on our users to improve the use of management, if you want to make your OLED live for a long time, less on the white as the base color of the website (as far as the base color is black), see less blue pictures, do not like to see the sea and sunny photos, see more green and red scenes and movies, red although the luminous efficiency is not good, but the life is very long
OLED is a PTT special aircraft and should be invincible in PTT durability
4. It consumes a lot of electricity when it emits white light;
Secondly, compared with the power consumption part of the LCD, it can be seen that the efficiency of the red and blue luminous parts is not very high. Therefore, if they emit the same light as the green ones, especially the white ones, then the black part will not emit light, which is very energy-efficient
OLED and LCD emit various colors of light power consumption comparison
5.PWM low-frequency dimming enterprises may be very damaging to the eyes:
What is low-frequency PWM? Because it has nothing to do with this topic, so if you want to know in detail please Google, PWM has high frequency and low frequency, low frequency may hurt your eyes, as long as you know this well, this is OLED technology can not overcome the current problem, because after all, self-lighting, at low brightness times will have this problem
