Abstract: Disclosed are a display panel and a display method thereof, and a display apparatus. The display panel includes multiple pixel units, a pixel unit includes multiple sub-pixels, a sub-pixel includes a pixel drive circuit, a sense compensation circuit, and an element to be driven, and the display panel further includes a detection unit and a compensator; the pixel drive circuit is configured to drive the element to be driven in active time; the sense compensation circuit is configured to sense electrical characteristics of the element to be driven in blank time; the detection unit is configured to detect whether a currently displayed picture is a still picture, send a first notification to the compensator when the currently displayed picture is a still picture, and send a second notification to the compensator when the currently displayed picture is a non-still picture.

Abstract: A system includes an imaging device that captures multichannel image data from a region of interest on a patient, one or more processors, and memory storing instructions. The memory storing instructions cause the one or more processors to receive the multichannel image data from the imaging device, such that the multichannel image data includes an image signal representative of plethysmographic waveform data for the region of interest and specular noise in the multichannel image data. Furthermore, the memory storing instructions cause the one or more processors to generate a projection matrix associated with the multichannel image data and iterate values of the projection matrix to remove the specular noise to generate a representative physiological signal, such that the representative physiological signal has an improved signal-to-noise ratio relative to the image signal and the representative physiological signal is a representative plethysmographic waveform.
