Display apparatus, control method, display device and computer storage medium

A method for controlling a display apparatus, comprising:

• acquiring voltages of a plurality of flex sensors connected in series in the display apparatus, wherein the plurality of flex sensors have, along a direction away from a reel, a plurality of arrangement serial numbers from small to large in a state where a flexible display panel is contracted;
• comparing the voltages of the plurality of flex sensors;
• acquiring an amount of voltage change and an arrangement serial number of a target flex sensor in response to a change in a voltage of at least one flex sensor of the plurality of flex sensors, the target flex sensor being a flex sensor with a largest arrangement serial number among the at least one flex sensor;
• and
• determining a sliding distance of the flexible display panel based on the amount of voltage change and the arrangement serial number, the sliding distance being a distance by which a reel drives the flexible display panel to move;
• wherein determining the sliding distance of the flexible display panel based on the amount of voltage change and the arrangement serial number comprises:
• acquiring a bending angle of the target flex sensor based on the amount of voltage change and a correspondence between the amount of voltage change and a bending angle of the flex sensor;
• acquiring a bending distance of the target flex sensor based on the bending angle;
• and
• determining the sliding distance based on a second formula:
• D=(m−1)×L1+L0;
• wherein D represents the sliding distance, m represents an arrangement serial number of a target flex sensor, L1 represents a length of the flex sensor in an arrangement direction of the plurality of flex sensors, and L0 represents the bending distance of the target flex sensor;
• wherein the length of the flex sensor in the arrangement direction of the plurality of flex sensors is one-half of a circumference of the reel;
• and
• acquiring the bending distance of the target flex sensor based on the bending angle comprises:
• determining the bending distance based on a third formula:
• L0=)(αm/180°×L1;
• wherein αm represents the bending angle of the target flex sensor.
