Abstract
An OLED display panel is provided and defined as: a display region, a bending region, and a driving bonding region, wherein the driving bonding region has: a driving chip; a flexible circuit board configured to achieve a connection between the driving chip and a motherboard; and a reinforcing plate disposed on and covered with a surface of the substrate wiring layer of the driving bonding region, wherein a chamber is formed in a bottom portion of the reinforcing plate, and the driving chip is located in the chamber.
Claims13
An OLED display panel, defined as:
- a display region comprising a first protective layer, a flexible substrate, a substrate wiring layer, and a display element layer which are sequentially stacked and disposed, wherein the flexible substrate and the substrate wiring layer are extended toward a side of the display region;
- a bending region being a first extending portion of the flexible substrate and the substrate wiring layer;
- and
- a driving bonding region being a second extending portion of the flexible substrate and the substrate wiring layer, wherein the second extending portion is located outside the first extending portion;
- wherein the driving bonding region comprises:
- a driving chip disposed on a surface of the substrate wiring layer and configured to input a voltage to each pixel;
- a flexible circuit board configured to achieve a connection between the driving chip and a motherboard;
- a reinforcing plate disposed on and covered with a surface of the substrate wiring layer of the driving bonding region, wherein a chamber is formed in a bottom portion of the reinforcing plate, and the driving chip is located in the chamber;
- and
- a first opening disposed in a top portion of the chamber of the reinforcing plate, wherein a plane at which the top portion of the chamber located is parallel and aligned to a top surface of the driving chip.
