A touch display screen and a preparation method, display apparatus and drive method therefor. The touch display screen includes: a first substrate and a second substrate arranged opposite each other; a first electrode and a second electrode arranged between the first substrate and the second substrate and capable of generating a horizontal electric field when in a powered-up state; a liquid crystal filled between the first substrate and the second substrate; and a touch sensing electrode provided at an outer side or an inner side of the second substrate. The liquid crystal includes a nematic phase liquid crystal and a long-chain compound dispersed in the nematic phase liquid crystal and enabling the nematic phase liquid crystal to be in a scattered state.
