Title:
OPTICAL SIGNAL NOSE REDUCTION CIRCUIT, OPTICAL SIGNAL NOISE REDUCTION METHOD, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/227987
Kind Code:
A1
Abstract:
The present invention provides an optical signal nose reduction circuit, an optical signal noise reduction method, and a display panel. The optical signal nose reduction circuit comprises a reference line, a comparison detection circuit, and a photoelectric signal read line. Electrical signals on the photoelectric signal read line comprise a noise electrical signal and a photoelectric signal. The reference line is used for sensing the noise electrical signal on the photoelectric signal read line to generate a corresponding electrical signal. The comparison detection circuit is separately connected to the reference line and the photoelectric signal read line, and is used for obtaining the photoelectric signal according to the electrical signal on the photoelectric signal read line and the electrical signal of the reference line.
