Title:
COLOR TEMPERATURE SENSOR AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/205206
Kind Code:
A1
Abstract:
Disclosed in the present application are a color temperature sensor and an electronic device. The color temperature sensor comprises a multispectral sensor, a light scattering film layer, a light incident window control part and a control circuit. When color temperature information in an environment needs to be sensed, light in the environment is first irradiated to the light incident window control part, and each incident light control unit in the light incident window control part can be in a light-transmitting state or a light-shielding state under the control of the control circuit. When light within a particular viewing angle range needs to be measured, the control circuit controls the incident light control unit at the position corresponding to the particular viewing angle range to be in a light-transmitting state, and the incident light control units at the remaining positions to be in a light-shielding state, so that only light within the particular viewing angle range can pass through the incident window control part and enter the light scattering film layer, and is irradiated to the multispectral sensor by means of the scattering effect of the light scattering film layer; therefore, the color temperature sensor can collect light from different viewing angles in a targeted manner, and has the capability of measuring color temperature information of light within a particular viewing angle range.
