The Nothing Phone (3) now features a lower pulse-width modulation (PWM) rate, which has sparked some concerns among users. This adjustment aims to enhance the display’s performance, particularly at lower brightness levels.
However, the specifics behind this decision have not been fully clarified by the company, which suggests it will be included in the final retail software update. PWM, or pulse-width modulation, is essential for controlling brightness on OLED displays.
It works by rapidly turning pixels on and off, creating the illusion of dimmer lighting. While this technology is generally harmless, a subset of people may experience adverse effects, such as eye strain, headaches, or even vertigo due to lower flicker rates.
The recent downgrade in the Phone (3) means that its PWM rate has shifted from 2,160Hz to 960Hz when operating at lower brightness. Despite this change, the display technically can still support a higher PWM rate, though it remains unclear at what brightness levels this capability is activated.
A spokesperson for Nothing has stated that this update intends to optimize picture quality at lower brightness levels. Concerns regarding PWM sensitivity aren’t exclusive to Nothing, as other smartphone manufacturers are also prioritizing this aspect in collaboration with user comfort.
For instance, the Honor Magic 6 Pro supports a significantly higher PWM rate when brightness drops beneath a specific threshold. Many feel that Nothing should be more transparent about these changes and perhaps provide users with options to prioritize PWM rates over image quality.
This would enhance accessibility, allowing individuals who are sensitive to PWM technology to use smartphones without experiencing negative effects. The balance between picture quality and user comfort should be an essential consideration for all smartphone brands.
