A display substrate, a display apparatus and a remote control system which are used to solve the problem in the existing touch control technologies that precise touch control cannot be performed on any region on a display device which is a certain distance away, wherein the display substrate comprises a base substrate (101), a colour filter (102a) located on the base substrate (101), and at least one optical recognition structure (104) located in a non-display region of the display substrate. By arranging the optical recognition structure (104) in the non-display region of the display substrate, the irradiation of a predetermined light beam is perceived, and a voltage signal is generated and is transmitted to an external circuit via a signal line connected thereto. |
