Problems solved by technology

However, most of the image sensors currently used are inorganic materials, which are high in cost, large in size, and heavy in weight; organic polymer materials have the advantages of low cost, light in weight, easy to process, and impact resistance, etc. The refractive index is usually between 1.3 and 1.7, which is difficult to meet the requirements of the microlens refractive index. At present, one of the most effective ways to improve the resolution of CIS is to use microlens (Innermicrolens) inside the CIS device. The optical signal is more effectively concentrated on the photodetector (photodetector), thereby increasing the resolution of the overall device [Suwa, M. Journal of Photopolymer Science Technology, 2006, 19, 275-276])
