Compensation circuit in which a magnitude relationship between channel width-to-length ratios of driving transistors of any two sub-pixels is identical with a magnitude relationship between channel width-to-length ratios of two sense transistors corresponding to the two sub-pixels, manufacturing method thereof, pixel circuit, compensation device and display device

A method of manufacturing a compensation circuit, comprising:

• determining channel width-to-length ratios between driving transistors of at least two sub-pixels in a pixel;
• determining channel width-to-length ratios of at least two sense transistors based on the channel width-to-length ratios of the driving transistors of the at least two sub-pixels, wherein the at least two sense transistors are in one-to-one correspondence to the at least two sub-pixels, a first electrode of each of the sense transistors is directly and electrically connected to a driving transistor of corresponding one of the sub-pixels, and a magnitude relationship between channel width-to-length ratios of driving transistors of any two sub-pixels of the at least two sub-pixels is identical with a magnitude relationship between channel width-to-length ratios of two sense transistors corresponding to the two sub-pixels;
• and
• manufacturing the at least two sense transistors based on the determined channel width-to-length ratios of the at least two sense transistors.
