Compared with Samsung ISOCELL, which is actively developing towards high resolution, and currently has reached 200MP high resolution, Sony’s IMX sensor is relatively focused on image performance and large pixel area, but it may be due to mobile phone customers’ demand for high resolution for marketing It is said that Sony will launch a new 1/1.33-inch component IMX802 for mobile phones, which will reach 108MP and will adopt a double-layer transistor structure.
▲ Sony proposed a double-layer transistor architecture in 2021, layering photodiodes and pixel transistors
Sony announced its double-layer transistor technology in 2021, which separates and stacks photodiodes and pixel transistors, which can double the saturation signal, greatly improve the dynamic range and reduce noise. The contrast environment can be better improved than the current single-layer transistor. It is mentioned in this leaked IMX802 data that this photosensitive element has 2x2CCL dual-pixel focusing technology, and reaching 108MP also means that the IMX802 should support the pixel 9-in-1 technology. It is usually used as a 12MP photosensitive element. After all, in There are not many situations where 108MP is required for daily use.
From the product characteristics and pixel area, I think IMX802 should not lock the demand of ultra-flagship products. After all, Sony has already provided 1-inch IMX989 components for smartphones. It is not difficult to understand the advantages of large components. The possible opponents of IMX802 are 200MP-class 1/1.4-inch Samsung ISOCELL HP3 and 1.3-inch ISOCELL HP2. The improved dynamic range should be the selling point of the IMX802.
