Abstract

The invention relates to a photoelectric sensor and a packaging method thereof. A plurality of photoelectric conversion chips distributed in an array are formed on a driving substrate; forming a protection unit wrapping each photoelectric conversion chip on the driving substrate; forming an isolation structure between the adjacent protection units on the driving substrate; forming a filtering unit on each protection unit; forming a lens unit on each filtering unit; a single photoelectric sensor is formed. The photoelectric sensor is internally provided with the photoelectric conversion chip arrays, the isolation structures located between the adjacent photoelectric conversion chips, and the filtering unit arrays and the lens unit arrays which are respectively arranged corresponding to the photoelectric conversion chip arrays, so that quantitative analysis can be realized, the process difficulty is low, the cost is also low, and higher application requirements of users on the photoelectric sensor are met; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of photoelectric sensors, in particular to a photoelectric sensor and a packaging method thereof. Background technique [0002] With the development of photoelectric sensors, the application scenarios of photoelectric sensors are becoming more and more extensive, such as using photoelectric sensors to realize proximity light detection or ambient light detection. The existing photoelectric sensor packaging forms are as follows: figure 1 As shown, an existing photoelectric sensor packaging form is: the photodiode chip 300 is fixed on the bracket 100 by the fixing glue 200, and the filter sealant 400 is formed on the photodiode chip 300, so as to realize the selectivity of the signal by the filter sealant Filter to receive bands for light intensity monitoring purposes. When this scheme is adopted, the filter range will change due to the long-term aging and deterioration of the glue, and there is a defect that the filte...
