Topic.
It should be noted that the pixel region that pixel defining layer defines is arranged in luminescent layer in Fig. 2, so to identify
Pixel region.
It should be noted that two pixel regions are drawn in Fig. 2 in a symmetrical and are set to shining for pixel region
Layer, draws symmetrically arranged anode, symmetrically arranged first via hole, the second via hole and target position, but practical mistake accordingly
Pixel region is not limited to two pixel regions in journey, and pixel region is not limited to symmetrically, with the definition of pixel defining layer in practice
On the basis of pixel region out.
It should be noted that the middle section Fig. 2 figure illustrates that cathode is the multiple portions of segmentation, but compliance display panel
Middle cathode layer can for whole face be arranged, only corresponding region be arranged the first via hole, similarly, pixel defining layer can whole face setting, only
In corresponding region, the second via hole is set.
It should be noted that due to being top light emitting flexible display panel in the embodiment of the present invention, and anode layer setting is existed
On luminescent layer, then anode layer material is transparent material, can be only achieved normal display effect, i.e. Anodic of embodiment of the present invention layer material
Material is transparent material, is no longer described in the following embodiments.
It should be noted that in embodiments of the present invention, cathode layer is arranged below luminescent layer, so that cathode electrode layer thickness
It can increase without influencing normal display, and the thickness of cathode layer increases so that the impedance of cathode layer reduces, so as to avoid aobvious
Show that pressure drop bring display problem occurs in panel.
It should be noted that anode connects down to target position by the first via hole and the second via hole, in target position
When in substrate intermediate region, there can be via hole in substrate, anode layer is made to be connectable to target position.
In one embodiment, as shown in Fig. 2, being provided with insulating layer 23 in first via hole, it is contemplated that anode layer meeting
Across the first via hole being arranged on cathode layer, and anode layer needs to insulate with cathode layer, and the embodiment of the present invention is in the first via hole
Middle setting insulating layer, so that anode layer, when passing through the first via hole, insulating layer ensure that anode layer and cathode layer insulate;In this hair
In bright embodiment, the size of the first via hole can be made to be greater than the part that anode layer extends downwardly, so that anode layer and cathode layer
Insulation, but when the not set interlayer of consideration, anode layer will appear the case where contacting with cathode layer, exhausted by being arranged in the first via hole
Edge layer, it is ensured that anode layer and cathode layer insulate.
In one embodiment, as shown in figure 3, substrate 21 includes planarization layer 211, the planarization layer is to the first via hole
24 extend to form insulating layer 212, by extending planarization layer into the first via hole, so that anode layer and cathode in the first via hole
Layer insulation, planarization layer in embodiments of the present invention, can be upwardly extended to form insulating layer, then existed when forming planarization layer
Cathode layer is formed on planarization layer, and cathode layer borehole is formed into the first via hole, so that insulating layer is equipped in the first via hole, thus
So that the anode layer and cathode layer in corresponding first via hole insulate.
In one embodiment, the substrate extends to form the first via hole to cathode layer, by prolonging the first substrate upwards
It stretches to form protrusion, borehole in protrusion is then formed into the first via hole, cathode layer is formed on the substrate, so that on cathode layer
It is provided with the first via hole, so that anode layer is passed through from the first via hole is connected to target position, in the present embodiment, due to lining
Bottom upwardly extends to form the first via hole, so that the first via hole as shown in Figure 3 can be formed, forms insulating layer in the first via hole,
The first via hole can also directly be formed, it is contemplated that substrate insulation, no setting is required, and insulating layer is the effect that can reach insulating layer.
In one embodiment, as shown in figure 4, pixel defining layer 28 extends to form insulating layer 281 into the first via hole 34,
In view of pixel defining layer is insulating materials, cathode layer 29 is being formed, after forming the first via hole 34, is forming pixel defining layer 28

35 and first via hole 24 when being connected to target position 22, it can guarantee anode layer 26 and cathode in the region of corresponding first via hole 34
Layer 29 insulate.
In one embodiment, as shown in figure 4, first via hole 34 and second via hole 35 are in target position 22
Projection is overlapped, and when forming the first via hole and the second via hole, first via hole and second via hole can be made to be in always
On line, and first via hole and second via hole are in the same size, so that anode layer can extend for connection to directly down
Target position.
In one embodiment, pixel defining layer extends to form the first via hole to cathode layer, forms the in pixel defining layer
When two via holes, pixel defining layer is extended to cathode layer, so that pixel defining layer forms the first via hole and the second via hole, and
Can make the first via hole and the second via hole the projection of target position be overlapped or pixel defining layer can be formed directly in the first via hole and
Second via hole is connected to the first via hole with the second via hole, so that anode layer extends for connection to target position directly down, together
When, since the first via hole is formed with the second via hole by pixel defining layer, then the first via hole with no setting is required in the second via hole absolutely
Edge layer, but the embodiment of the present invention is not limited to this, such as better insulation effect, it can be in the first via hole and the second via hole
Insulating layer is set.
In one embodiment, projection of first via hole with the second via hole in target position is not overlapped, in practical mistake
Cheng Zhong needs to be formed the second via hole in pixel defining layer, but when forming the first via hole makes anode layer be connected to target position,
First via hole can be arranged in above target position, not weigh to will appear projection of first via hole with the second via hole in target position
It closes, needs the first Via Design to be bending to connect the second via hole and target position;Or by the second Via Design be bending
Shape so that its connect first via hole.
In one embodiment, the insulating layer includes water oxygen isolation layer, in the first via hole and the second via hole, it may appear that
The phenomenon that water and oxygen corrode anode and cathode and water and oxygen can enter and corrode metal on array layer on array layer
Problem, the embodiment of the present invention can directly choose the material for completely cutting off effect and insulation effect with water oxygen and make when insulating layer is arranged
For insulating layer, or the setting water oxygen isolation layer inside insulating layer, to achieve the effect that protect anode, cathode, and protect
Metal on respective array layer.
In one embodiment, the laminated construction of inorganic layer, organic layer can be used in the water oxygen isolation layer, or uses nothing
Machine layer will not be reacted choosing with water sample isolation layer with the metal of anode layer, cathode layer and array layer as water oxygen isolation layer
The material of water intaking oxygen barrier.
In one embodiment, due to being arranged cathode layer below luminescent layer, the light that luminescent layer issues will not be through
Cathode layer is crossed, then can make the material opaque material of cathode layer, in embodiments of the present invention, can choose that flexible, impedance is small, leads
The material of excellent electrical properties can also choose transparent material as cathode, such as tin indium oxide, indium zinc oxide etc. as cathode.
In one embodiment, the material of the anode layer includes tin indium oxide, indium zinc oxide, the material choosing of anode layer
It takes, when not influencing the normal work of anode layer, chooses the material with good light permeability as far as possible, and anode layer is thinned to mention
High light transmittance.
