Under-screen camera tech? Oppo’s got the edge!

August 10, 2021

Oppo have officially announced its next-generation under-screen camera (USC) technology for smartphones. By combining the best in hardware innovation and proprietary AI algorithms, the new under-screen camera solution discreetly places the front-facing camera under the smartphone display in a way that maintains the integrity and consistency of the entire screen, both during use and while in standby. Offering the perfect balance between consistent screen quality and camera image quality, it is an under-screen camera solution with no compromises.

This new under-screen camera solution solves many technical and manufacturing-related challenges that have plagued under-screen camera technology since the beginning of its development. Breakthroughs include resolving issues such as inconsistent display quality in the screen area above the under-screen camera, poor image quality caused by obstruction of the camera by the screen, as well as issues with product reliability and lifespan.

Oppo stresses several new innovations in structure design and AI algorithms this next-generation under-screen camera solution introduces:

  • Innovative pixel geometry: the new solution shrinks the size of each pixel without decreasing the number of pixels to ensure a 400-PPI high-quality display even in the camera area.
  • Transparent wiring and new design: Oppo have replaced the traditional screen wiring with an innovative transparent wiring material. Combined with a high-precision manufacturing process that reduces the width of the wiring by 50%, this results in much finer display quality with a smoother visual experience.
  • Improved control of screen accuracy, color, and brightness: in contrast to the current industry standard of using 1 pixel circuit to drive 2 pixels (“1-to-2”) in the screen area above the camera, has introduced a new solution using proprietary screen technology, with each pixel circuit driving only 1 pixel (“1-to-1”). When combined with algorithmic compensation technology, this allows the chromaticity and brightness of the entire screen to be precisely controlled with a deviation of about 2%. For uses such as reading e-books, browsing the news, or navigating with maps, the under-screen camera technology allows for the accurate display of smaller fonts and better preservation and representation of textural details and colors, resulting in a more consistent and immersive experience.
  • Improved reliability and lifespan: with the introduction of the “1-to-1” pixel circuit and dedicated optimization algorithm, Oppo’s next-generation under-screen camera solution is able to provide display compensation in the under-screen camera area of screen, improving the screen’s lifespan by up to 50%.

Oppo has released three generations of under-screen camera solutions to date since it began its development of the technology in 2018, applying for over 200 related patents in the process. In 2020, Oppo also made submission of its first proposed standards for under-screen camera technology to the International Electrotechnical Commission (IEC). Included in the submitted proposal were recommendations for seven key technical metrics including display transmittance, reflectance, uniformity, Gamma correction, color shift and brightness decay.
