At the same time, based on the presence of many noise signals in the device, during the transmission of the detection signal through the wiring, it is very likely that the voltage coupling of the display or touch will cause additional and serious noise signals to the detection signal.
In general, in signal processing, if the frequency of the noise falls within the frequency band of the detection signal, it is very difficult to achieve a better filtering effect.
[0003] Therefore, in the process of implementing the present application, the inventor found that it is difficult to effectively eliminate the interference caused by noise signals in the equipment or in the external environment by obtaining related signals in existing equipment

The invention discloses an anti-noise signal modulation circuit, a jump method, a display panel, and a display device, and relates to the technical field of signal anti-noise processing. The anti-noise signal modulation circuit includes a frequency modulation control sub-circuit; the frequency modulation control The input terminal of the subcircuit is used to receive the initial signal, and the output terminal of the frequency modulation control subcircuit is connected to the preset signal processing circuit; The switching signal is frequency modulated and then output to the signal processing circuit; the frequency corresponding to the switching signal avoids the noise frequency. The anti-noise signal modulation circuit, modulation method and display device perform frequency modulation on the acquired initial signal, so that the frequency of the initial signal is different from the frequency of the noise, and the subsequent processing can effectively eliminate the interference of the noise signal, and improve the initial signal for subsequent filtering. and processing accuracy and reliability.
Description
technical field [0001] The present invention relates to the related technical field of signal anti-noise processing, in particular to an anti-noise signal modulation circuit, a modulation method, a display panel, and a display device. Background technique [0002] Signal detection is of great significance in many devices. It not only enables users to know the real state of device-related information in a timely manner, but also facilitates further processing based on the relevant state. For example: in the field of display-related technologies, it is usually necessary to use the characteristics of detection sensors that change with the environment to convert them into currents or voltages and input them to signal processing circuits for related signal detection. Based on the different detection requirements, the detection sensor integrated on the display may be set at any position on the display; when the detection sensor is far away from the signal processing circuit that p...
