To adapt to market trends, flagship smartphones from various brands now predominantly use OLED screens, while LCD screens are gradually being phased out. To maintain market competitiveness and product positioning, Apple has followed this trend, with the iPhone 11 being the last generation to feature an LCD screen.The reasons for the popularity of OLED screens are as follows:1. OLED screens offer superior display quality: OLED screens are self-illuminating, capable of presenting deeper blacks and higher contrast, with more vibrant and rich colors, resulting in an outstanding visual experience.2. OLED screens are lighter and thinner: OLED screens do not require a backlight layer, leading to a simpler structure and thinner profile, which benefits the design of slimmer smartphones and saves space for other internal components, such as larger batteries.3. The technology for OLED screens has matured, leading to reduced costs: With technological advancements, the production costs of OLED screens have gradually decreased, while the yield rates have continuously improved. Under the effects of scale, the cost advantages have become increasingly apparent.4. Facilitates product design: OLED screens can achieve flexible displays and irregular cuts, supporting higher screen-to-body ratios, such as full-screen and curved screens, meeting consumer aesthetic demands for smartphone appearances. They can also use COP packaging methods to reduce screen bezels.The iPhone 11 can be considered the last model in Apple’s mainstream series to use an LCD screen.Detailed specifications of the iPhone 11:Appearance: Dimensions and weight: Width 75.7 mm, Height 150.9 mm, Thickness 8.3 mm, Weight 194 grams.

Despite using the iPhone 11 for five to six years, it remains the primary device for many users. Budget is one reason, but another is the natural eye protection level of LCD screens. Moreover, the LCD used by Apple is almost at the pinnacle of eye protection for smartphones. I continue to use the iPhone 11 for eye comfort, even though I wish to have a 48-megapixel camera and high optical zoom. Unfortunately, I have sensitive eyes and experience tears and headaches with OLED screens. I truly hope Apple will offer different screen options for high-end models, but it seems they have abandoned the wishes of this small group of sensitive users. What phone are you still using? In fact, current smartphone performance is severely over-supplied; we don’t need to pursue the latest and greatest. Money isn’t easy to earn, and opting for second-hand devices with good value is a solid choice. We have consistently maintained quality and reputation in the second-hand market.
