[0030] refer to image 3 with Figure 4 , the display device of this embodiment is different from the display device of the prior art in that it additionally has a partition wall 17 . The setting of the partition wall 17 is to ensure that the COF 16 will not be disconnected from the driving electrode 15, so as to ensure the reliable transmission of the driving signal.

[0031] The display device includes a substrate 11, which may be formed of any suitable insulating material having flexibility. For example, it can be made of polyimide (PI), polycarbonate (PC), polyethersulfone (PES), polyethylene terephthalate (PET), polyethylene naphthalate (PEN) , polyarylate (PAR) or glass fiber reinforced plastic (FRP) and other polymer materials. The substrate 11 may also be rigid, such as glass.

[0032] The substrate 11 includes a display area and a non-display area, wherein the display area includes a display device 12, which may be an OLED display device, a mini-LED display device...

Abstract

The invention provides a display panel, a display screen and display equipment. A partition wall is arranged near a cofferdam to accommodate the anisotropic conductive adhesive and is matched with thebulge part of a cover plate to press the chip-on-film, so that the bonding reliability of the chip-on-film is ensured. In other embodiments, a supporting column is further arranged to protect and support the chip-on-film.

Description

technical field [0001] The invention relates to the technical field of luminescent display, in particular to a display panel, a display screen and a display device. Background technique [0002] Currently, a display device often includes a display area and a non-display area, and the display area often requires an external drive module, and the drive module is connected to the non-display area through a chip-on-chip film to drive a display device in the display area. For details, please refer to figure 1 with figure 2 , the display device includes a substrate 1 and a display area and a non-display area on the substrate, the display area includes a display device 2 and a bank 3 surrounding the display device 2, and the bank 3 has a cover covering the The sealing layer 4 of the display device 2, the drive electrode 5 extends from the display area to the non-display area, and passes through the bottom of the bank 3, and the chip-on-chip film 6 is bonded to the drive electrod...
