Core Viewpoint - The mobile phone industry is exploring the adoption of ultra-high refresh rate screens, specifically 165Hz, as companies like REDMI and OnePlus are investigating this technology, potentially signaling a shift towards higher refresh rates in smartphones [1][3][10]. Group 1: Current Market Trends - The mainstream refresh rate for mobile phones is currently 120Hz, with some mid-range devices featuring 144Hz. However, the practical benefits of moving from 120Hz to 144Hz are minimal, leading to skepticism about the necessity of 165Hz screens [3][6]. - The 165Hz refresh rate offers a 37.5% improvement over 120Hz, but the actual user experience may not significantly differ due to software limitations, as many applications are locked at lower frame rates [6][10]. Group 2: Technical and Economic Considerations - The introduction of 165Hz screens may face challenges such as increased costs and power consumption, which could negatively impact battery life and overall device performance [7][10]. - Historical examples, like the Sharp Aquos Zero2 with a 240Hz screen, illustrate that high refresh rates can be underutilized if software does not support them, leading to a disconnect between hardware capabilities and user experience [7][10]. Group 3: Future Outlook - Despite current limitations, the push for 165Hz screens could drive competition among manufacturers, potentially leading to broader adoption and improved software support in the future [15][18]. - The competition for high refresh rates is part of a larger strategy for companies to define "smooth experience" in mobile devices, with early adopters likely gaining a competitive edge [18][23].

Core Viewpoint - Apple has initiated a two-year production plan to implement advanced OLED technology in iPhone models, with dual-layer OLED expected to debut after 2028 [1] Group 1: Technology Development - The iPad Pro has already commercialized dual-layer OLED screens, known as "Tandem OLED," which adds an extra layer of light-emitting material to traditional single-layer OLED [1] - This design allows the light-emitting demands to be distributed across two layers, significantly reducing the electric field intensity on each layer and slowing down the aging of the light-emitting materials [1] - The theoretical brightness of dual-layer OLED can reach twice that of single-layer OLED, providing users with a brighter display while addressing issues like light leakage [1] Group 2: Application in iPhone - The dual-layer OLED technology for iPhone will differ slightly from existing solutions, as Apple will only stack the blue sub-pixels in a dual-layer configuration, while the red and green sub-pixels will remain single-layer [1] - This approach is referred to as a "simplified dual-layer OLED" within the industry [1]
