Rimless display device and preparation method thereof
A rimless display device and a preparation method thereof, the rimless display device comprises a flexible substrate formed on a rigid base plate ( 1 ), the flexible substrate is provided with a display region ( 2 ) having an organic light-emitting layer arranged therein and a non-display region ( 3 ), wherein, after a part of the rigid base plate at a location corresponding to the non-display region ( 3 ) is removed, the non-display region ( 3 ) of the flexible substrate is fixed on a lateral surface or a rear surface of the display device after the non-display region ( 3 ) is folded. This rimless display device can achieve a real rimless display screen body, thereby further increasing the screen proportion and greatly improving the view effect.
1. A rimless display device, comprising
a flexible substrate, provided with a display region having an organic light-emitting layer arranged therein and a non-display region;
wherein the non-display region of the flexible substrate is fixed on a lateral surface or a rear surface of the display device after the non-display region is folded,
wherein the non-display region is provided with an integrated circuit zone and a gate driving circuit zone, and the gate driving circuit zone has a hollowed-out structure.
2. The rimless display device according to claim 1 , wherein the flexible substrate is placed on a rigid base plate.
3. The rimless display device according to claim 1 , wherein the non-display region is fixed on a lateral surface or a rear surface of the display device after the non-display region is folded along a boundary between the display region and the non-display region.
4. The rimless display device according to claim 1 , wherein the parts of the non-display region on two neighboring sides of the display region have a disconnected structure.
5. The rimless display device according to claim 4 , further comprising a drive circuit board assembly arranged on a side of the rigid base plate away from the organic light-emitting layer, wherein, the drive circuit board assembly and the display region have overlapping projections on the flexible substrate.
6. The rimless display device according to claim 5 , wherein when the rimless display device is a top-emitting display device, the non-display region is fixed on a rear surface of the drive circuit board assembly after the non-display region is folded; when the rimless display device is a bottom-emitting display device, the non-display region is fixed on a lateral surface of the drive circuit board assembly after the non-display region is folded.
