Abstract: A touch substrate, a display apparatus and a display system are provided. By rearranging and distributing transistors in each shift register, the number of transistors in a lateral direction is less than that of transistors in a longitudinal direction. That is a circuit structure of the shift register is designed to extend longitudinally, so that a size of the shift register in the lateral direction can be reduced, a narrow frame design is realized, and seamless splicing is favorably realized in a large-sized display panel.
