The present disclosure relates to the field of display technologies, and in particular to a flexible support member, display module, and mobile terminal.
In recent years, flexible display products have attracted extensive attention. Flexible display products include fixed curved products, foldable products, expandable screen products, rollable products, etc. As bending areas are widened, corresponding rigid support areas are widened, resulting in reduced rebound force of rigid support components, thereby extremely reducing supporting and restoring of the rigid support components.
