Problems solved by technology

[0006] In order to prevent a part of the binding portion 120 from being peeled off from the flexible substrate 110, the usual method is to improve the composition of the conductive adhesive used to make the conductive adhesive 300, but the cost of research and development is high.

Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] After repeated research by the inventors of the present invention, it has been found that one of the main reasons for the insufficient binding strength between the driver chip and the display panel is that the part where the binding part is in contact with the flexible substrate is mostly made of inorganic materials, and inorganic materials often pass through the gas phase. The deposition method is formed on a flexible substrate made of organic materials, and the bonding strength between inorganic materials and organic materials is low.

[0043] In view of this, as an aspect of the present invention, a display device is provided, such as figure 2 and ...

Abstract

The invention provides a display device including a flexible display panel and a driving chip disposed on the flexible display panel. The flexible display panel includes a flexible substrate and a binding portion formed on a side of the flexible substrate towards the driving chip. The driving chip is attached to the binding portion. The binding portion is provided with at least one connection hole penetrating through the binding portion in a thickness direction. The display device further includes a conductive bonding layer made of conductive paste. The conductive bonding layer is bonded between the driving chip and the binding portion. A portion of the conductive bonding layer fills the connection hole. A portion of the conductive bonding layer located in the connection hole is bonded between the flexible substrate and the driving chip. The display device is low in cost. Not only is the driving chip firmly bonded to the binding portion, but also the binding portion is less likely to fall off from the flexible substrate. The invention also provides a binding method of the driving chip.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a method for binding a driving chip in the display device. Background technique [0002] The display device includes a display panel and a driver chip that provides driving signals for the display panel. Usually, a binding part is provided in the binding area of ​​the display panel, and the driver chip is bonded to the binding part to realize the binding of the driver chip. [0003] According to different substrates used, display devices can be classified into two types: flexible display devices and rigid display devices. [0004] figure 1 Shown in is a cross-sectional view of the flexible display device in the binding area, as shown in the figure, the flexible substrate 110 is provided with a binding part 120, and the driving chip 200 is bound to the binding part 120 through a conductive adhesive layer 300 . [0005] However, in the flexible disp...
