Abstract

A level shift circuit converts input signals in a first voltage domain into output signals in a second voltage domain. The level shift circuit includes a first voltage domain circuit, a middle voltage domain circuit, and a second voltage domain circuit. The middle voltage domain circuit convert the signals in the first voltage domain received by the first voltage domain circuit into signals in a middle voltage domain. The second voltage domain circuit converts the signals in the middle voltage domain into signals in the second voltage domain and outputs the converted signals. The signals in the middle voltage domain are partly different from the signals in the first voltage domain and the second voltage domain. Each signal in the first voltage domain is different from the signals in the second voltage domain. A display apparatus is also disclosed.
