The biggest visual difference between AMOLED and LCD display screens is that AMOLED displays a wider color gamut, allowing it to display more colors, and the display will be more realistic. In addition, the saturation of AMOLED screens is high when displaying blue and green, so in the early days AMOLED screens were often criticized for inaccurate colors and being too bright. LCD screens typically overcompensate for red and suppress green compared to AMOLED screens, which, while not as wide as AMOLED screens, are actually closer to the standard RGB color gambit used in video and photo editing.
A closer look at some phones with AMOLED screens and some with LCD display screens also shows some differences. The screens, for example, come from Samsung, but the blackberry Priv still has a slightly different gamut than the Galaxy Note5, and even more so than the LG V10, which USES an LCD screen. So in addition to the material itself, the manufacturer's adjustment of the screen color is also very important.
In addition to color gamut, color accuracy is also a very important evaluation index. In tests, the AMOLED display screen has been shown to perform extremely well, especially when it's actually white. The blackberry Priv and Galaxy Note 5 display white close to the actual white, while the LCD screen is usually a bit bluish or greenish. Of course, given that LCD display screens typically use blue-light backlighting, this is no surprise.
In addition, the need to use a backlight layer, and the backlight layer can not be completely closed, resulting in TFT-LCD display screen leakage and low contrast, such as less than perfect. As AMOLED display screens are self-luminous, the relatively bright blue light in them may cause color drift with the increase of use time, while TFT-LCD has no such problem.
TFT-LCD and AMOLED can be said to have their own advantages and disadvantages, and with the continuous optimization of TFT-LCD technology and the improvement of AMOLED technology, in fact, in some high-end mobile phones, the gap between TFT-LCD and AMOLED has been very small, not enough to make a huge impact on daily use. However, OLED display screens are more likely to be the future of the display industry because of their increasing power consumption, thickness and display performance, as well as lower costs as the technology matures and mass production. At the same time, TFT-LCD screens are likely to be squeezed into the mid - to low-end market.
