Smartphone covers all have distance sensor holes and camera holes. Due to different functional applications, different IR inks need to be applied to the holes on the phone cover. The light transmittance through the IR ink holes determines the light transmittance performance of different hole positions. Therefore, the IR hole transmittance is a very important parameter for mobile phones. Jingyi Optoelectronics has developed a light transmittance detector with various solutions including manual detection, semi-automatic detection, and fully automatic detection to meet your different product needs

With the development of the mobile phone industry, important indicators such as adhesion, bonding, hydrophobicity, and cleanliness of mobile phone covers and films have received increasing attention and are considered crucial for mobile phones. The contact angle tester developed by Jingyi Optoelectronics is an analytical technology for surface treatment. It can be used for testing the hydrophobicity and cleanliness of mobile phone covers and films, which is of great significance for product process control, quality assurance, and failure analysis

With the development of technology and the improvement of living standards, people's pursuit of better photo and video experiences has led to the continuous evolution of mobile phone cameras. The performance of mobile phone photography is related to factors such as sensors and pixels. Therefore, in order to improve the performance of mobile phone photography, it is necessary to calibrate the spectrum and brightness of mobile phone cameras. The mobile phone camera spectrum calibration system developed by Jingyi Optoelectronics is a novel optical metrology system that uses a uniform standard calibration light source, allowing for adjustable brightness and color temperature. It replaces the traditional use of multiple light sources and comparison procedures in spectral response testing, simplifies steps, and greatly improves the production and testing efficiency of ambient light sensors
