Abstract

The invention belongs to the field of photoelectrons and discloses an image sensing device. The image sensing device comprises a plurality of organic photosensitive units arranged on a same substrate, and insulating isolation columns for partitioning the organic photosensitive units and carrying out optical isolation on the adjacent organic photosensitive units are arranged between the adjacent organic photosensitive units. The organic photosensitive units are adopted as signal conversion components, so that the integration level is high and the flexibility can be achieved. Meanwhile, signal reading and collecting are carried out on the organic photosensitive units in a row-by-row and column-by-column scanning manner, so that the structure of the image sensing device is effectively simplified; the preparation technology and process are extremely simple; and the product yield is high.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to an image sensing device and a method for preparing and using the same. Background technique [0002] The image sensing device is developed on the basis of optoelectronic technology. It uses the photoelectric conversion function of photoelectric devices to convert the optical signal on the photosensitive surface into an electrical signal "image" that is proportional to the optical signal. Technology, which converts optical images into electrical signals, the key lies in the integration of photosensitive devices and the acquisition of output signals. [0003] Existing image detection systems that mainly use photosensitive devices include solid-state optical image sensing systems, infrared imaging systems, etc., which have been widely used in video, measurement, monitoring, medical treatment, artificial intelligence and other fields. [0004] A common solid-state optical image sensin...
