Why is the graininess of OLED screen more obvious than that of LCD at the same resolution?

TFT screen is currently the most commonly used and most common material on the screen of mobile phones, TFT full TFT--ThinFilmTransistor thin film transistor, is one of the active matrix type liquid crystal display AM-LCD, TFT sets a special light tube on the back of the LCD, which can actively control each independent pixel on the screen, which can greatly improve the reaction time.

It's not horizontal and vertical, in the case of low screen pixel density ppi, there will be a sense of jagged when displaying horizontal and vertical fonts or**, which is because the red and blue pixels are arranged in a straight line at a 45° angle.

Traditional LCD screens use RGB (red, green, blue) standard arrangement, and the three sub-pixels of RGB are the same in size and number.

Actually, it's pretty much the same, but everyone's feelings are different.

The granularity of the OLED screen is more obvious than that of the LCD.

OLED has become the preferred screen for flagship phones due to its excellent characteristics such as thinness and bright colors.

The traditional LCD screen adopts RGB (red, green, blue) standard arrangement, which is the preferred screen for flagship computers.

Most flagship smartphones use OLED

OLED screens have moved to the center of the historical stage, and most flagship smartphones on the market currently use OLED

OLED screens have moved to the center of the stage of history.

At the same resolution, the LCD is clearer due to the innate arrangement.

What is the difference between OLED screen and LCD, compared with two mobile phones with different screens, the gap is too big.

OLED screens are indeed clearer than LCD screens. As a high-end display, OLED is much better than traditional LCD screens in terms of display effect, thinness, color accuracy, and image contrast accuracy.

OLED (Organic Light Emitting Display) is an organic light-emitting display, which is a new type of product on the LCD of mobile phones, and is known as"Dream display"。

Unlike traditional LCD displays, OLED display technology does not require a backlight and uses a very thin coating of organic materials and a glass substrate that emits light when an electric current passes through it. Moreover, OLED display screens can be made lighter and thinner, with larger viewing angles, and can significantly save power.

Among the two major technical systems of OLED, the low-molecular OLED technology is mastered by Japan, and the technology and patents of the polymer PLED (the so-called OEL of LG mobile phones are the products of this system) are mastered by the British technology company CDT, and there are still certain difficulties in the colorization of PLED products compared with the two.

However, although OLED, which is more technologically advanced, may replace LCD such as TFT in the future, there are still shortcomings in organic light-emitting display technology, such as short service life and difficulty in making the screen larger.

The new generation of OLED display technology has overcome the problems of short service life (more than 30,000 hours) and difficulty in making the screen larger (more than inches).

Introduction: Because AM is Samsung's name for OLED, let's discuss the advantages and disadvantages of OLED and LCD. In terms of advantages, LCD, as a traditional mobile phone screen, is more mature, has a longer service life and does not hurt the eyes, and the cost is also lower.

OLED is thinner and therefore lighter, and it has higher color contrast and softer than LCD. In terms of disadvantages, LCD is more power-hungry and it is heavier than OLED, not as superior in terms of display color. The disadvantage of OLED is that it will continue to flicker in order to dim and then cause people's eyes to be very dry, because the material is very thin, so the screen burning will also shorten the service life of the mobile phone.

Now there are two main types of mobile phone screens, OLED and LCD, OLED is the standard screen of flagship mobile phones, LCD is used in general mobile phones, so LCD technology is more mature than OLED. In terms of making materials, OLED does not require many layers of manufacturing materials like LCD, so it can achieve functions that LCD does not have. Because it is thinner and lighter than LCD, it can often use the special function of flexible screen and under-screen fingerprint.

Therefore, compared with LCD, OLED is often the material of folding screen mobile phones. <>

Then in terms of color display, OLED has certain advantages compared with LCD, because the thickness of LCD is thicker, so the black it displays is often not so standard. The color of OLED display is more standard, and the color contrast is higher. In terms of power consumption, LEDs work separately with pixels, unlike LCDs, which need to be backlit to be fully on, so it will consume more power.

In terms of disadvantages, because OLED needs to constantly turn on and off the screen to dim the screen, this high-frequency screen flicker will cause certain damage to the human eye. Because OLED uses organic materials, it is thinner and its service life is not as long as that of inorganic materials, so there may be screen burn-in. However, OLED, as a new type of material, belongs to the screen of the future.

The principle of OLED screen and LCD screen, let's talk about the luminous principle of these two screens, the material of OLED screen is organic photodiode, when the mobile phone is charged, it can be self-luminous, and no other materials are needed to assist. On the other hand, the LCD screen can't do this, if you want the LCD to emit light, then it needs the backlight layer, polarizer and other materials to assist, so it is more troublesome to emit light. Advantages and disadvantages of OLED screens Due to the different luminous principles, the color, frequency, and thickness of OLED screens are also different compared with LCD, so their advantages and disadvantages are obvious.

Advantages and disadvantages: 1. Since the OLED screen is a self-luminous material, its thickness is very thin, and the curvature and foldability are very good. Therefore, OLED screens are widely used in folding screen mobile phones and curved screen mobile phones.

2. Due to the principle of OLED screen self-luminescence, screen fingerprint unlocking can be done with OLED screen. 3. Since the OLED screen is relatively thin and light, the mobile phone equipped with the OLED screen can be thinner and lighter.

OLED screen has advantages in thinness, display, power consumption, etc., but disadvantages: the aging rate of the light-emitting unit is much faster than that of LCD materials, and it is prone to flicker problems.

There is no doubt that in terms of clarity is of course the LCD screen is better, but in rising to 2K resolution.

After that, the human eye perception will be very inconspicuous, and the 2K OLED screen.

The overall performance will be far better than the LCD screen.

In the current mobile phone screen, the arrangement of pixels can be divided into standard RGB arrangement and Pentile arrangement according to different categories, among which the RGB arrangement is mainly based on the LCD screen, and the pixel density of the OLED screen is at the same resolution.

It's basically equivalent to about 80% of an LCD screen.

Why should the OLED screen choose the Pentile arrangement instead of the more detailed RGB arrangement? This involves the problem of OLED screen material.

The light-emitting material of the OLED screen is an organic light-emitting material, his biggest feature is that it can be self-luminous and can also display colors, while the LCD screen provides a light source through the LED backplane, but this organic light-emitting material has a disadvantage that the life is not as good as the inorganic material on the LCD screen.

When the screen resolution.

After all upgrades to 2k, due to marginal effects.

The human eye will perceive the difference in clarity between OLED screen and LCD screen less and less obviously, because its PPI has far exceeded the retina.

326ppi is defined, so there is no value in talking about clarity after 2k. However, in terms of screen brightness, viewing angle, contrast, and color saturation, OLED screens crush LCD screens, so mobile phones that are still using 2K LCD screens are basically extinct.
