Title:
IN-SCREEN OPTICAL APPARATUS AND METHOD FOR DETECTING PROTECTIVE FILM ON DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2022/000471
Kind Code:
A1
Abstract:
An in-screen optical apparatus and a method for detecting a protective film on a display screen. The in-screen optical device is suitable for a terminal device having a display screen, and the in-screen optical device comprises an optical sensor module, which is provided below the display screen so as to implement the acquisition of in-screen optical images. The optical sensor module comprises an optical sensor, which comprises an optical sensing array having multiple photosensitive pixels and which is used for receiving a detection light signal formed by reflecting or scattering, on a target object above the display screen, detection light emitted by a detection light source, and converting the received detection optical signal into an electrical signal, the electrical signal being used for detecting the size of a light spot formed by the detection light signal on the optical sensor. In the described method, it can be determined whether a protective film is provided on the display screen, and, according to the result of protective film detection, algorithm optimization is performed for optical image acquisition or processing.
