Oppo’s upcoming Find X10 series will use Tianma’s new Tiangong Screen 2.0, a high-end OLED panel that puts more emphasis on eye comfort and low-brightness performance. The second-generation OLED panel was unveiled today at Tianma’s OLED technology event in Xiamen.
The main change with the new screen is in the OLED materials themselves. Tiangong Screen 2.0 uses a new primary-color light-emitting material, which Tianma calls N1 primary-color spectrum material.
The company has made changes to the blue, green, and red parts of the OLED spectrum. For blue, it uses NFB fluorescent blue technology, which is designed to improve efficiency while reducing harmful blue light. Tianma says this increases luminous efficiency by 16% and extends the material’s lifespan by 33%.
For green, the panel uses PSF phosphorescence technology. Tianma says this improves luminous efficiency by 11% and increases the green color gamut by 6.7%.
The red component uses DRT deep red light technology. Tianma says it tested nearly 100 deep red light materials and carried out almost 700 sets of comparisons during development. The result is a higher proportion of deep red light in the panel’s output.
Together, these changes also alter the screen’s light spectrum. Tianma says harmful blue light makes up just 3.7% of the spectrum, while deep red light in the 650nm to 670nm range reaches 5.5%.
Color gamut and low-light
The panel also offers native 95% coverage of the BT.2020 color gamut and a Delta E of below 0.6, targeting accurate and natural color reproduction. Tianma says brightness uniformity has also been improved, particularly at low brightness levels.
For low-light viewing, Tiangong Screen 2.0 uses Tianma’s AI De-Mura algorithm. The company says it improves low-brightness uniformity by 30% and allows the screen to reach as low as 0.01 nits while maintaining better brightness and color consistency.
Tianma has also worked on the panel’s TFT backplane to improve uniformity. The company claims the new screen has a 30% longer lifespan than the previous generation.
The display builds on Oppo’s work with low-brightness screens. The Find X9 series introduced a 1-nit low-light display, while the Find X10 series will bring the newer Tiangong Screen 2.0 technology.
The Find X10 series is expected to launch in September. Oppo has yet to reveal the full display specifications, including the screen size, resolution, refresh rate, and peak brightness.
