Abstract

A flexible display screen and a flexible display apparatus are provided. The flexible display screen includes a display device, a flexible substrate, a support structure and a drive chip. The display device is positioned on the flexible substrate, and the flexible substrate is positioned on the support structure. The support structure further defines a groove thereon to accommodate the drive chip.

First claim

What is claimed is:

1. A flexible display screen, comprising:
a display device,
a flexible substrate, the display device being positioned on the flexible substrate,
a drive chip, and
a support structure, the flexible substrate being positioned on the support structure, the support structure defining a groove accommodating the drive chip,
wherein the support structure comprises a support film, a cushioning member, and a heat-dissipating member, the support film being positioned on the cushioning member, the cushioning member being positioned on the heat-dissipating member, and the flexible substrate being positioned on the support film,
wherein the heat-dissipating member is a copper foil, and
wherein the groove extends toward the display device across the heat-dissipating member and the cushioning member to be sequentially disposed in the support film.

2. The flexible display screen according to claim 1 , wherein, a thickness of the support structure is equal to or larger than a thickness of the drive chip.

3. The flexible display screen according to claim 2 , wherein, a shape and a position of the groove match a shape and a position of the drive chip.

4. The flexible display screen according to claim 1 , wherein, the display device in the flexible display screen is an Organic Light Emitting Diode (OLED).

5. The flexible display screen according to claim 1 , wherein, the drive chip is positioned on a flexible circuit board.

6. The flexible display screen according to claim 1 , wherein a cross section of a portion of the groove within the heat-dissipating member is greater than a cross section of a portion of the groove within the cushioning member.

7. The flexible display screen according to claim 1 , wherein a cross section of a portion of the groove within the cushioning member is greater than a cross section of a portion of the groove within the support film.

8. The flexible display screen according to claim 1 , wherein a shape of the groove is trapezoidal.

9. A flexible display apparatus, comprising a flexible display screen which comprises:
a display device,
a flexible substrate, the display device being positioned on the flexible substrate,
a drive chip, and
a support structure, the flexible substrate being positioned on the support structure, the support structure defining a groove accommodating the drive chip,
wherein the support structure comprises a support film, a cushioning member, and a heat-dissipating member, the support film being positioned on the cushioning member, the cushioning member being positioned on the heat-dissipating member, and the flexible substrate being positioned on the support film,
wherein the heat-dissipating member is a copper foil, and
wherein the groove extends toward the display device across the heat-dissipating member and the cushioning member to be sequentially disposed in the support film.

10. The flexible display apparatus according to claim 9 , wherein, a thickness of the support structure is equal to or larger than a thickness of the drive chip.

11. The flexible display apparatus according to claim 10 , wherein, a shape and a position of the groove match a shape and a position of the drive chip.

12. The flexible display apparatus according to claim 9 , wherein, the display device in the flexible display screen is an OLED.

13. The flexible display apparatus according to claim 9 , wherein, the drive chip is positioned on a flexible circuit board.
