Key reasons for the widespread adoption of OLED screens

When we mention OLED screens, we have to mention their outstanding display quality. Due to their self-emissive nature, OLED screens have far superior contrast to passive-light LCD screens. In today's era of mobile phones with rapidly upgrading cameras, a screen with high contrast and high color saturation allows the advantages of the camera to be clearly seen, which is also an important reason why Samsung invested heavily in AMOLED research in its early days.

As Apple, which has always attached importance to film and television production and output, also needs to equip the iPhone with a good screen to ensure that its display quality is as consistent as possible with its desktop production tools. Starting with the iPhone X, Apple has been emphasizing the importance of High Dynamic Range imaging (HDR) in mobile content production. On the iPhone 12, Apple also added Dolby Vision hardware and software support for the first time.

In addition to professional productivity tools and content sharing, OLED screens also have inherent advantages in content consumption. They have better viewing angles, richer color displays, and higher display performance than "white" LCD screens. In addition to high display quality, OLED screens have many small advantages: the local light-emitting characteristics of OLED screens are suitable for introducing interest screen display functions, allowing users to check the time and other statuses without distraction; because the deflection of liquid crystals is greatly affected by temperature, obvious trailing will appear on LCD screens in sub-zero temperature environments, but there is no need to worry about organic light-emitting diodes. Of course, the development of OLED screens has also brought many new problems, but through technological improvements, the usability of organic light-emitting diode screens has greatly improved compared to previous years. Judging from the current popularity of OLED screen mobile phones, mid-range flagship OLED screens will not be as full as before, and can support three years under normal use, and mass consumers have already gained a preliminary acceptance of organic light-emitting diode screens.

Modern mobile phone screens: In the early days, an important reason for the popularity of OLED screens was their thinness and flexibility. The COP packaging launched by Samsung for the full-screen era greatly reduced the bezels of mobile phones and optimized the visual aesthetics of the full-screen design, although some LCD models have already achieved screen ratios comparable to COP packaging. However, as the Size of mobile phone screens has grown to its peak, in order to achieve high heat dissipation for large batteries, screen thickness must be sacrificed, and thinner organic light-emitting diode screens have become the preferred choice. In addition to being thin and light, OLED screens' extremely low response delay also provides a complete hardware foundation for high-screen touch control. Because the deflection speed of liquid crystals is relatively slow, many LCD models will experience trailing problems in high-refresh-rate environments. Even the iPad Pro, which boasts a 120Hz refresh rate with dynamic refresh rate enhancement, still has trailing problems reported by many users.

In recent years, the rapid development of under-screen optical fingerprint and under-screen cameras has driven another nail into the coffin of LCD screens. Organic materials have a certain degree of transparency, providing unique protection for sensors and cameras. They can be placed under the screen, while OLED screen models can only use facial recognition or side fingerprint methods. Punch-hole screens are difficult to gain marketing advantages in today's market.
