With the continuous development of technology, there are more and more types of cell phone screens, of which the more common are OLED and IPS screens. So, which is better, OLED or IPS screen? The following is a detailed description.
First, OLED screen
OLED screen is the abbreviation of organic light-emitting diode screen, it is a new type of display technology, with self-luminous, high contrast, high brightness, fast response, low power consumption, etc. Each pixel of the OLED screen is composed of red, green and blue organic materials, which can realize the true all-black, because the black pixel point does not need to be light-emitting, so it can achieve a very high contrast. In addition, OLED screens are very responsive and can reach the millisecond level, so they have a very good performance in watching videos, playing games and so on.
The disadvantage of OLED screen is mainly the problem of life span, because the life span of organic materials is limited, so the life span of OLED screen is relatively short, especially the life span of blue pixel points is even shorter. In addition, the price of OLED screen is relatively high because of the high manufacturing cost.
Second, IPS screen
IPS screen is the abbreviation of wide viewing angle liquid crystal screen, it is a liquid crystal display technology, with wide viewing angle, high color saturation, color reproduction, etc. Each pixel point of IPS screen is composed of liquid crystal molecules, which can be changed by controlling the electric field to change the direction of the liquid crystal molecules, so as to realize the pixel point display.The color reproduction of the IPS screen is very high, and it can achieve a very real color performance, so it has a very good performance in image processing, design and other aspects.
The disadvantage of IPS screen is mainly the contrast problem. Due to the optical nature of liquid crystal molecules, the contrast of IPS screen is relatively low, and the black performance is not as good as OLED screen. In addition, the response speed of the IPS screen is relatively slow, and problems such as residual shadows may occur.
Third, the comparison of OLED screen and IPS screen
1. Contrast: OLED screens have a very high contrast ratio and can reach unlimited contrast, while IPS screens have a relatively low contrast ratio.
2. Color performance: OLED screens have very good color performance and can achieve true all-black, while IPS screens also have good color performance, but black performance is not as good as OLED screens.
3. Response speed: OLED screen response speed is very fast, can reach the millisecond level, while the response speed of IPS screen is relatively slow.
4. Viewing angle: IPS screen has a very wide viewing angle, which can reach 178 degrees, while the viewing angle of OLED screen is relatively narrow.
5. Lifespan: OLED screens have a relatively short lifespan, especially for blue pixels, while IPS screens have a relatively long lifespan.
In summary, OLED screen and IPS screen have their own advantages and disadvantages, the choice of which screen mainly depends on personal needs. If the pursuit of high contrast, fast response, true black and other aspects, you can choose OLED screen; if the pursuit of wide viewing angle, high color saturation, color reproduction and other aspects, you can choose IPS screen. Of course, price is also a consideration, OLED screen price is relatively high, while the IPS screen price is relatively low.
