TCL has launched the Nxtpaper 70 Pro smartphone with a flicker-free display that feels and looks like paper, according to the company. Along with other eye health technologies, the phone might help reduce headaches and eye strain for those who are sensitive to flickering screens and harsh glare.

Digital display eyestrain and Nxtpaper 4.0 technology

Modern computing devices from laptops to tablets often employ a glossy display to help increase the contrast of displayed images. These screens also often use pulse width modulation (PWM) to adjust the screen brightness. Glossy displays produce harsh glare while PWM generates rapid light flickering, both of which cause serious health problems in users who are sensitive to them, such as eye strain, headaches, and nausea.

The phone leverages Nxtpaper 4.0 nano-matrix lithography on the top glass to create a paper-like surface that has low glare, according to TCL. A circular polarizer alters the light output to potentially counter dry eye and eye fatigue, while a physical light filter modifies the light output to contain lower levels of potentially harmful blue light. A DC backlight regulator eliminates PWM light flickering to potentially reduce headaches, nausea, vertigo, and seizures.

The Nxtpaper 70 Pro is powered by an 8-core MediaTek Dimensity 7300 SoC with 8 GB of RAM, and 256 or 512 GB of storage running Android 16. Available RAM can be expanded to 24 GB total through the use of virtual RAM, and storage can be expanded by up to 2 TB using a microSD card. The phone has Bluetooth 5.4 and Wi-Fi wireless connectivity.

Users can switch the 120 Hz, 1,080 x 2,340 LCD display between regular color mode, monochrome ink paper mode, and monochrome max ink mode at any time using the dedicated Nxtpaper button. The optional T-pen stylus can sense 4,096 pressure levels when taking lecture notes or drawing diagrams, and attaches to the optional stand case.

Users can take high-resolution photos and videos thanks to a 50 MP 1/1.56″ main rear camera, an 8 MP 1/4″ ultrawide rear camera, and a 32 MP 1/3″ front camera, dual mics, and dual speakers. AI-powered translations, subtitles, text summaries, and voice-transcription capabilities are also included.

The internal 5,200 mAh battery can be fast charged at 33W. The IP68-rated phone weighs 7.3 oz. (208 g) and measures ‎6.67 x 3.15 x 0.31 in. (169.4 x 80.05 x 7.98 mm).
