Flexible support plate and display apparatus

A display apparatus, comprising:

• a flexible support plate and a display module disposed on the flexible support plate;
• wherein the flexible support plate comprises a first support plate;
• wherein
• the first support plate is provided with a first flat region and a roll-slide region that are connected to each other;
• and
• the first support plate comprises a wholly-plate-shaped structure disposed in the first flat region and a plate-shaped structure disposed in the roll-slide region and provided with a plurality of hollowed-out regions;
• wherein in the roll-slide region, proportions of total areas of the hollowed-out regions in unit areas monotonically decrease along a first direction, such that capabilities of the flexible support plate to absorb stress and strain, in the roll-slide region, monotonically decrease along the first direction, the first direction being a direction from the first flat region to the roll-slide region,
• wherein the first support plate further comprises:
• a first boundary support bar, a second boundary support bar, and a plurality of support bars that are disposed in the roll-slide region;
• wherein one end of the first boundary support bar and one end of the second boundary support bar are connected to a first side edge of the wholly-plate-shaped structure, the first boundary support bar and the second boundary support bar both extend along the first direction, the other end of the first boundary support bar is connected to the other end of the second boundary support bar by a second side edge of a connection plate, and the plurality of support bars are connected between the first boundary support bar and the second boundary support bar to define the plurality of hollowed-out regions,
• wherein the plurality of support bars comprises a plurality of first support bars and a plurality of second support bars;
• wherein the plurality of first support bars are parallel to each other, two ends of each of the first support bars are respectively connected to the first boundary support bar and the second boundary support bar, and distances between two adjacent first support bars monotonically decrease along the first direction;
• wherein a portion of the plurality of second support bars is connected between any two adjacent first support bars to define the plurality of hollowed-out regions,
• wherein the portion of the plurality of second support bars connected between any two adjacent first support bars comprises a plurality of first unit structures arranged along a second direction, any of the plurality of first unit structures comprising a first section, a second section, a third section, a fourth section, and a fifth section, wherein the first section is disposed between two adjacent first support bars and extends along the second direction, one end of the first section is connected to the two adjacent first support bars respectively by the second section and the third section, and the other end of the first section is connected to the two adjacent first support bars respectively by the fourth section and the fifth section;
• and
• in the second direction and in any two adjacent first unit structures, the fourth section of one of the any two adjacent first unit structures and the second section of the other of the any two adjacent first unit structures are connected to the same point of the same support bar, and the fifth section of one of the any two adjacent first unit structures and the third section of the other of the any two adjacent first unit structures are connected to the same point of the same first support bar;
• wherein the second direction is an extension direction of a roll-slide shaft when the roll-slide region rolls and slides and is perpendicular to the first direction, and each of the first section to the fifth section is respectively one of the plurality of second support bars.
