The position detection sensor is fixedly arranged on one side surface of the operation plate of the first shell, which is close to the roller, and the detection of the relative sliding position state of the first shell and the second shell is realized by detecting the distance between the position detection sensor and one end of the first side wall or the second side wall of the first shell, which is close to the operation plate.

9. The electronic device of claim 7, wherein the position detection sensor is a hall sensor assembly, and the magnetic member of the hall sensor assembly and the hall sensor receiver are disposed opposite to each other and are respectively fixed on the first side wall and/or the second side wall of the first housing and the first support plate and/or the second support plate of the second housing.

10. The electronic device of claim 9, wherein the plurality of magnetic elements of the hall sensor assembly are sequentially arranged on the outer side surfaces of the first support plate and the second support plate of the second housing away from the top plate along the direction in which the first housing and the second housing slide relatively; the Hall sensing assembly comprises at least two Hall sensing receivers and is respectively and fixedly arranged on the inner sides of the first side wall and the second side wall of the first shell.

11. A display control method based on the electronic device according to any one of claims 1 to 10, comprising:

detecting a relative sliding position of the first housing and the second housing using a position detection sensor;

And controlling the state of the display area of the flexible display screen according to the information of the relative sliding position of the first shell and the second shell.

12. The display control method according to claim 11, wherein the state of the flexible display screen display area includes a position of the flexible display screen display area and an area of the flexible display screen display area.
