Patent attributes
A photosensor chip package structure comprises a substrate, a light-emitting chip and a photosensor chip including an ambient light sensing unit and a proximity sensing unit. The substrate has a first basin, a second basin and a light-guiding channel. The openings of the first and second basins respectively face different directions. One opening of the light-guiding channel and the opening of the first basin face the same direction. The other opening of the light-guiding channel interconnects with the second basin. The light-emitting chip is arranged in the first basin. The photosensor chip is arranged in the second basin. The light-guiding channel conducts the light generated by the light-emitting chip and the ambient light to the photosensor chip. The photosensor chip operates as soon as it receives the light generated by the light-emitting chip and/or the ambient light.
