Rimless display device and preparation method thereof

A method of making a rimless display device, comprising the following steps:

• (1) providing a flexible substrate on a rigid base plate, the flexible substrate having a display region and a non-display region, and providing a drive circuit board assembly on one side of the rigid base plate away from the flexible substrate;
• (2) preparing an organic light-emitting layer in the display region, and preparing integrated circuit and gate driving circuit in the non-display region, and making a part of the non-display region where the gate driving circuit is located into a hollowed-out structure;
• (3) removing a part of the rigid base plate at a location corresponding to the non-display region, and fixing the non-display region on a lateral surface or a rear surface of the drive circuit board assembly after folding the non-display region.
