Mobile phone screen: Is the OLED screen good, or is the LCD screen good? For mobile phones, I believe that everyone is no stranger. The quality of a mobile phone is good and bad. Presumably, in addition to performance considerations, the most important thing is the screen. It can be said that the screen is a window for people to communicate with, and the quality of the screen is also determined. The quality of mobile phones, mobile phone screens on the market are divided into OLED screens and LCD screens . So what is the best of these two screens? Mobile phone screen: Is the OLED screen good, or is the LCD screen good? But with the maturity of OLED technology, Samsung screens are used by many manufacturers, such as one plus, Meizu, OPPO and so on. Even the iPhone8, which is rumored to be released soon, will use Samsung's OLED screen . It can be said that OLED is the future trend. Why is OLED so popular now? Advantage 1: Thin and light. The thinness of the mobile phone can be said to be the trend of the times. It takes a lot of effort for the manufacturer to make the mobile phone thin and light. For example, cancel the 3.5mm headphone hole, compress the board space, etc. The same OLED screen advantage is thin: look at this thickness, at a glance. Advantage 2: Bending performance. OLED's screen and LCD structure are different, OLED screen bending performance is very good, so Samsung S7E and S8 can be greatly bent, while LCD screen bending performance is limited, curved LCD screen intelligence on the TV or display. Advantage 3: High contrast. Since the pure black of the OLED does not emit light, the OLED screen is blacker, has a higher contrast, and is more power efficient.
Compared with OLED display and LED display, which one has advantages Most of us now use LED display screens, LED display screens, and a kind of OLED display , which is a new product, which is now widely used. Then, OLED technology and LED technology have advantages. As long as it is clearer than a little, the following is a small introduction for everyone. Compared with OLED display and LED display, which one has advantages Comparison of OLED display and LED display A typical LED display may have a lot of blue light, which many consumers dislike because it can harm our body and harm our health. The LED display is likely to reduce everyone's sleep. The light emitted by the OLED display is soft, making the eyes comfortable, and many consumers prefer this product. Advantages of OLED display The OLED display is a piece of organic material sandwiched between the currents of the two electrodes. OLEDs can self-illuminate, using ultra-thin organic materials. When current is passed, the materials used to make the OLEDs will illuminate and save power. The OLED material is very soft, which makes it easier to mount on a desk lamp. Today's OLED technology surpasses TV and mobile phones, and many OLED manufacturers are inventing more products for everyone to use. It is reported that most of the OLED display lamps are used for student learning and convenience, and the eye irritation is very low. Therefore, for students, it is more important to buy a suitable display screen, and this display screen stimulates the eyes. The role is very small, so gradually replace the LED display, becoming the first choice for future displays.
Are there differences between OLED displays and AMOLED display diodes? OLED display and AMOLED display diode, do they have differences? Tuo Xiaobian to analyze and analyze with everyone, although LED is more common in daily life, but in the screen, each LED is very small in size, and It is divided into three sub-pixel groups of red, green and blue, and then different colors are formed, and the arrangement of sub-pixels also affects the overall display effect. The O in AMOLED stands for Organic, which is "organic". Simply put, a series of organic film materials are used between the positive and negative electrodes to achieve the purpose of illuminating. Are there differences between OLED displays and AMOLED display diodes? AMOLED belongs to OLED, but the reverse is not the case. Simply put, OLED technology includes PMOLED and AMOLED. PMOLED does not require TFT backplane (different from liquid crystal backplane), but the size cannot be made very large; AMOLED size can be made very large. PMOLED is mainly used in early dual-screen mobile phones for small external screens. Currently, mobile TVs use AMOLED technology. OLED is an organic light-emitting diode, and its luminescent material is an organic luminescent material, which is relative to an LED light-emitting diode. As long as the OLED is charged with the correct voltage at the positive and negative poles, it will illuminate, and the light bulb is the same. When it is signaled, he will work. AMOLED is an active organic light-emitting diode. It not only needs to add signal, but also needs to supply additional point source to make the diode work. When it gives a bright or no light signal, it will light or shut down. It's not an inappropriate analogy. It works like a TV. You pick up a wired signal, but you can't see it. You only have to pay for it. But only to give electricity, not to cable signals, there is no program to watch. From a structural point of view, the OLED is basically a diode, and the AMOLED is a three-stage tube or a plurality of transistors to jointly drive one light-emitting point.
The OLED screen of the mobile phone has been seen for a long time, and is it harmful to the eyes? The OLED screen is also a type of LCD screen , so it does not cause eye damage. OLEDs, or organic light-emitting diodes, also known as organic electro-laser displays, have been widely used in players since 2003 because of their slimness and power-saving characteristics. For DCs that are also digital products. With mobile phones, engineering samples using OLED screens have only been shown at some exhibitions, and have not yet entered the stage of practical application. The OLED screen of the mobile phone has been seen for a long time, and is it harmful to the eyes? But OLED screens have many advantages that LCDs can't match, so it has always been favored by the industry. Unlike traditional LCD displays, OLED display technology eliminates the need for backlights and uses very thin organic coatings and glass substrates that illuminate when current is passed through. And OLED display screen can be made lighter and thinner, larger viewing angle, and can significantly save power. At present, in the two major technical systems of OLED, low-molecular OLED technology is mastered in Japan, and the so-called OEL of polymer PLEDLG mobile phone is this system. The technology and patents are controlled by the British technology company CDT. The display unit of each OLED can be controlled to produce three different colors of light. Like LCDs, OLEDs are also active and passive. The unit selected by the row and column address in the passive mode is lit. In the active mode, there is a thin film transistor (TFT) behind the OLED unit, and the light emitting unit is lit under the TFT driving. Active OLEDs are more power efficient, but passive OLEDs offer better performance.
