Flexible display substrate, method for controlling same, and display device

A display device, comprising a flexible display substrate, wherein the flexible display substrate comprises:

• a flexible base, having a display region and a bonding region;
• and
• a touch module, on a side of the flexible base, and having a plurality of touch electrodes, wherein each of the touch electrodes is connected to one connecting line, the touch electrodes are inside the display region, and the connecting line extends to the bonding region, and
• at least two of the connecting lines are connected to at least one pair of capacitor metal blocks, each pair of the capacitor metal blocks are symmetrically distributed along a bending line, and the flexible base is allowed to be bent along the bending line.

A method for controlling a flexible display substrate, wherein the flexible display substrate comprises:

• a flexible base, having a display region and a bonding region;
• and a touch module, on a side of the flexible base, and having a plurality of touch electrodes, wherein each of the touch electrodes is connected to one connecting line, the touch electrodes are inside the display region, the connecting line extends to the bonding region, at least two of the connecting lines are connected to at least one pair of capacitor metal blocks, each pair of the capacitor metal blocks are symmetrically distributed along a bending line, and the flexible base is allowed to be bent along the bending line;
• and the method comprises:
• determining a state of the flexible display substrate based on a capacitance between each pair of capacitor metal blocks;
• and
• determining an on/off status of each of the touch electrodes in the touch module based on a bent state of the flexible display substrate.
