Referring to fig. 1, fig. 1 is a schematic cross-sectional structure of a display panel 100 according to an embodiment of the present invention, and the components of the embodiment according to the present invention and the relative positional relationship of the components can be seen in a visual manner.
As shown in fig. 1, the display panel 100 has a display area a and a bonding area B disposed adjacently, and the display panel 100 includes at least a substrate 110, a pixel circuit 120, a driving circuit 130, a first connection terminal 140, a second connection terminal 150, a first protective adhesive 160 and a second protective adhesive 170, and the above components will be described in detail with reference to fig. 1.
The substrate 110 has a first surface 110a and a second surface 110B opposite to each other, the pixel circuit 120 and the driving circuit 130 are respectively disposed on the first surface 110a and the second surface 110B, the pixel circuit 120 is located in the display area a, and the first connection terminal 140 and the second connection terminal 150 are located in the binding area B and are respectively disposed on the first surface 110a and the second surface 110B.
It should be noted that, the display panel 100 in the embodiment of the invention is manufactured by a double-sided process, and the display panel 100 can achieve seamless splicing of the display device. Specifically, the pixel circuit 120 formed on the first surface 110a is a thin film transistor (Thin Film Transistor, TFT) circuit corresponding to each light emitting device (reference numeral 190 in fig. 2), the driving circuit 130 is configured to receive a driving signal, and the first connection terminal 140 and the second connection terminal 150 respectively disposed on the first surface 110a and the second surface 110b are configured to transmit the driving signal to the thin film transistor circuit, so that the corresponding light emitting device emits light.
As a result of the studies of the present inventors, it was found that in the process of manufacturing such a display panel 100, it is generally selected to attach an insulating protective film on the entire first surface 110a and the second surface 110, and then, a metal film layer for coupling the first connection terminal 140 and the second connection terminal 150 is deposited using a physical vapor deposition (Physical Vapor Deposition, PVD) process, however, in this embodiment, since the insulating protective film is easily peeled off (peeling) and thus, during the process of depositing the metal film layer, metal may extend to the display area a of the display panel 100, thereby causing problems such as short circuits (short) to occur, which seriously affect the reliability of signal transmission in the display panel 100.
Referring back to fig. 1, as shown in fig. 1, in the embodiment of the present invention, the inventor designs to add a first protective adhesive 160 and a second protective adhesive 170 on the first surface 110a and the second surface 110B, respectively, where the first protective adhesive 160 and the second protective adhesive 170 cover the first connection terminal 140 and the second connection terminal 150 along a first direction X1, and the first direction X1 is a direction in which the display area a points to the binding area B.
It should be noted that, in the embodiment of the present invention, since the first protective adhesive 160 and the second protective adhesive 170 that partially cover the first connection terminal 140 and the second connection terminal 150 are added to the display panel 100, on one hand, the first connection terminal 140 and the second connection terminal 150 that are exposed outside the first protective adhesive 160 and the second protective adhesive 170 can ensure that signals of the pixel circuit 120 and the driving circuit 130 are led out, and on the other hand, the first protective adhesive 160 and the second protective adhesive 170 that partially cover the first connection terminal 140 and the second connection terminal 150 can block that metal extends to the display area a of the display panel 100 when a metal film layer is deposited subsequently, thereby ensuring the reliability of signal transmission in the display panel 100.
Specifically, in the embodiment of the present invention, the first protective adhesive 160 and the second protective adhesive 170 are insulating materials, which include, but are not limited to, at least one of epoxy resin and phenolic resin, and the first protective adhesive 160 and the second protective adhesive 170 have strong adhesion, specifically, have a viscosity of 10pas.
Further, as shown in fig. 1, there is an intersection line S between the display area a and the binding area B, and in this embodiment, in order to further improve the protection effect of the first protective adhesive 160 and the second protective adhesive 170, the first protective adhesive 160 and the second protective adhesive 170 extend to the intersection line S along a second direction X2 opposite to the first direction X1, respectively.
It should be understood that, in other modifications of the present invention, the first protective adhesive 160 and the second protective adhesive 170 may also extend along the second direction X2 to a position adjacent to the boundary line S, which is not limited by the present invention.
Specifically, in the embodiment of the present invention, the first connection terminal 140 and the second connection terminal 150 have a first length (not labeled) in a third direction (not labeled) perpendicular to the first direction X1, and the first protective adhesive 160 and the second protective adhesive 170 have a second length (not labeled) in the third direction, so that the first length is smaller than the second length in order to ensure that the first protective adhesive 160 and the second protective adhesive 170 will block positions where metal films will be deposited later.
Further, please refer to fig. 2, which illustrates a schematic cross-sectional structure of a display panel 100 according to an embodiment of the present invention.
