Abstract

A flexible display panel includes a non display part and at least a first screen, a second screen and a third screen. The first screen and the second screen are oppositely located. The third screen is connected between the first screen and the second screen. The first screen, the second screen and the third screen jointly form a display region. The non display part is connected to one side of the display region and is provided with a drive chip that drives the first screen, the second screen and the third screen to show images.

First claim

What is claimed is:

1. A flexible display panel, comprising a non display part, a first screen, a second screen, a third screen, and a fourth screen,
wherein the first screen and the second screen are arranged opposite to each other and each have two opposite sides;
the third screen is arranged beside the first screen and the second screen and has two opposite sides respectively corresponding to the first screen and the second screen, the two opposite sides of the third screen being each connected to a first one of the two opposite sides of a respective one of the first and second screens to have the third screen connected between the first and second screens; and
the fourth screen is arranged beside the first screen and the second screen and opposite to the third screen and has the fourth screen having two opposite sides, the two opposite sides of the fourth screen respectively corresponding to the first and second screens, the two opposite sides of the fourth screen being each connected to a second one of the two opposite sides of a respective one of the first and second screens to have the fourth screen connected between the first and second screens;
wherein the first screen, the second screen, the third screen, and the fourth screen are connected in sequence to each other to form a closed tubular configuration having an outer circumferential surface that defines a circumferential display region including four sub display zones respectively formed of the first, second, third, and fourth screens; and
wherein the non display part is connected to one side of the display region and is provided with a drive chip, which is operable to drive the four sub display zones of the display region respectively formed of the first screen, the second screen, the third screen, and the fourth screen to show images.

2. The flexible display panel according to claim 1 , wherein a first connection part is connected between the first screen and the third screen; a second connection part is connected between the second screen and the third screen; a third connection part is connected between the first screen and the fourth screen; and a fourth connection part is connected between the second screen and the fourth screen.

3. The flexible display panel according to claim 1 , wherein each of the first screen, the second screen, the third screen, and the fourth screen is individually coated with a transparent conductive thin film layer, which forms a touch control unit for said each of the first screen, the second screen, the third screen, and the fourth screen, and the non display part is provided with a touch control chip that is electrically connected to the touch control units of the first, second, third, and fourth screens to realize a touch control function.

4. A flexible display apparatus, comprising a main body and a flexible display panel,
wherein the flexible display panel comprises a non display part, a first screen, a second screen, a third screen, and a fourth screen,
wherein the first screen and the second screen are arranged opposite to each other and each have two opposite sides;
the third screen is arranged beside the first screen and the second screen and has two opposite sides respectively corresponding to the first screen and the second screen, the two opposite sides of the third screen being each connected to a first one of the two opposite sides of a respective one of the first and second screens to have the third screen connected between the first and second screens; and
the fourth screen is arranged beside the first screen and the second screen and opposite to the third screen, the fourth screen having two opposite sides, the two opposite sides of the fourth screen respectively corresponding to the first and second screens, the two opposite sides of the fourth screen being each connected to a second one of the two opposite sides of a respective one of the first and second screens to have the fourth screen connected between the first and second screens;
wherein the first screen, the second screen, the third screen, and the fourth screen are connected in sequence to each other to form a closed tubular configuration having an outer circumferential surface that defines a circumferential display region including four sub display zones respectively defined by the first, second, third, and fourth screens; and
wherein the non display part is connected to one side of the display region and is provided with a drive chip, which is operable to drive the four sub display zones of the display region respectively formed of the first screen, the second screen, the third screen, and the fourth screen to show images; and
wherein the main body comprises a front side, a rear side, and two lateral sides connecting the front side and the rear side, the first screen being arranged on the front side, the second screen being arranged on the rear side, the third and fourth screens being respectively arranged to correspond to the lateral sides, such that the closed tubular configuration encloses the main body.

5. The flexible display apparatus according to claim 4 , wherein a first connection part is connected between the first screen and the third screen; a second connection part is connected between the second screen and the third screen; a third connection part is connected between the first screen and the fourth screen; and a fourth connection part is connected between the second screen and the fourth screen.

6. The flexible display apparatus according to claim 4 , wherein each of the first screen, the second screen, the third screen, and the fourth screen is individually coated with a transparent conductive thin film layer, which forms a touch control unit for said each of the first screen, the second screen, the third screen, and the fourth screen, and the non display part is provided with a touch control chip that is electrically connected to the touch control units to realize a touch control function.

7. The flexible display apparatus according to claim 4 , wherein the main body comprises a system main board, which is connected to the flexible display panel and controls the drive chip to drive the flexible display panel to show the images.

8. The flexible display apparatus according to claim 7 , further comprising a glass panel covering on the flexible display panel to protect the flexible display panel.

9. The flexible display apparatus according to claim 8 , wherein the glass panel comprises a first part, a second part, a third part, and a fourth part, which are arranged to respectively cover the first screen, the second screen, the third screen, and the fourth screen, the first, second, third, and fourth parts of the glass panel being connected in sequence to each other to form a closed tubular configuration that encloses and covers the flexible display panel.

10. The flexible display apparatus according to claim 4 , wherein the main body further comprises a battery, which is received in a battery jar located between the system main board and the second screen.
