Mobile/Tablet Application

5G Mobile Phone

5G will bring lower latency online gaming and augmented reality (AR) applications on mobile phones At present, the number of video frames has been increased from 60Hz to 90~120Hz, including the corresponding increase in refreshing rate, which will lead to more challenging sensing light and color under the screen in the future.

Full Screen or High Screen-Body Ratio Mobile Phone

  • The large screen brings users a better experience.
  • The Slit-type Proximity and ambient light sensors are hidden under the slits of the phone bezel, this requirement makes the integration of optical sensors and mechanisms highly challenging.
  • Many AMOLED mobile phone projects choose the under-display solution to avoid the harsh assembly nightmare, but the AMOLED screen itself emits light, causing interference, and an algorithm needs to be used to correct the ambient light.


  • More and more mobile phones are switching to AMOLED screens, because AMOLED screens are actively emitting light and exhibit superior grayscale resolution.
  • Eminent AMOLED under-screen light distance sensor provides driver software with algorithm to improve system integration efficiency.

Foldable Phone

The foldable phone is a new trend in mobile phones. It combines the advantages of traditional mobile phones and tablets, in addition to retaining all the functions of mobile phones. In video conferencing mode, you can open the wide screen to enjoy the experience of a tablet computer, and you can also have a comfortable reading e-book mode. A larger screen is better for users to view photos together when friends gather.

  • In the foldable phone, there will be an ambient light sensor placed in the folded position and an ambient light sensor-proximity 2-in-1 sensor will be placed under the inner screen or the outer screen of the phone. It is estimated that each folded Mobile phones will each place an ambient light sensor under the screen-proximity 2-in-1 sensor and at least another single-function ambient light sensor.
  • Flicker detection is used in recording mode to enable the phone to synchronize the flicker frequency of the ambient light. Under-screen flicker detection will be used to prevent image streaks.

Night Shooting Function

Night shooting function will be a major competitive indicator for smartphones in the future.

  • The Optical sensor (ambient light sensor, RGB color temperature sensor) mounted on the back cover is to improve the night shooting function of the rear camera.
  • RGB color temperature sensor enhances the camera's white balance function in low light conditions.
  • Flicker detection is used in recording mode to synchronize the flicker frequency of the ambient light. Flicker detection in video mode will be used to prevent image streaks .
