BIOMETRIC SENSING MODULE

The invention discloses a biological characteristic sensing module which comprises a light splitting material layer, an infrared light cut-off layer and a plurality of light sensing elements. The infrared light cut-off layer is located below the light splitting material layer. The transmittance of the infrared light cut-off layer in a wavelength range of 400 nm to 590 nm is greater than 50%, and the transmittance of the infrared light cut-off layer in a wavelength range of 590 nm to 630 nm is greater than 10% and less than 60%. The photosensitive element is located below the infrared light cut-off layer. 本发明公开一种生物特征感测模块，其包含分光材料层、红外光截止层以及多个感光元件。红外光截止层位于分光材料层下方。红外光截止层在波长400纳米至590纳米的范围中的穿透率为大于50％，且红外光截止层在波长590纳米至630纳米的范围中的穿透率为大于10％且小于60％。感光元件位于红外光截止层下方。
