Specific implementation mode
In order to make the purpose of the present invention, technical solution and advantage are clearer, below in conjunction with the accompanying drawings, to the embodiment of the present invention
The display panel of offer, its production method, the specific implementation mode of organic light emitting display panel and display panel carry out in detail
Explanation.
Each layer film thickness and shape do not reflect that the actual proportions of display panel, purpose are schematically illustrate hair in attached drawing
Bright content.
In the prior art, as shown in Figure 1, flexible OLED display panel includes underlay substrate 01, underlay substrate 01 includes aobvious
Show region and neighboring area AA, neighboring area AA is only illustrated in Fig. 1, includes covering completely on the underlay substrate 01 of neighboring area AA
The barrier layer 02 of lid underlay substrate 01 is located at the buffer layer 03 of 02 top of barrier layer, is located at the gate insulator of 03 top of buffer layer
Layer 04 is located at the interlayer dielectric layer 05 of 04 top of gate insulating layer and is located at 05 top encapsulated layer 06 of interlayer dielectric layer, due to
Cutting line a is located at the edge of neighboring area AA, and the prior art is to be cut to obtain single display surface using laser technology
Plate, since laser energy is larger, nearby film layer such as barrier layer 02 is easy to be heated and be hit to easy to produce crackle (figure cutting line a
Middle arrow direction), crackle, which inwardly conducts, enters viewing area, and black group is caused to influence the display effect of display panel.
In view of this, an embodiment of the present invention provides a kind of display panels, as shown in Figures 2 to 6, including underlay substrate
01, underlay substrate 01 includes display area and surrounds the neighboring area AA of display area, only illustrates neighboring area AA in figure, shows
Show that panel further includes at least one layer of protective layer at least covering cutting region bb corresponding with the cutting line a at the neighboring area edges AA
07。
Above-mentioned display panel provided in an embodiment of the present invention, since protection is arranged at the edge of neighboring area in the display panel
Layer, when subsequently being cut using laser technology, which can absorb laser energy and release impact force, prevent edge
Film layer is heated and is hit and cracks and spread to viewing area, is led in the prior art because laser intensity is excessive to solve
Cause cutting region film layer easy to produce crackle, the crackle inwardly conduct into viewing area and influence display the problem of.
Further, in order to effectively absorb laser energy and release impact force, provided in an embodiment of the present invention above-mentioned
In display panel, the material of protective layer is organic material.
Further, in above-mentioned display panel provided in an embodiment of the present invention, display panel further include planarization layer, as
Element defines layer and spacer layer；One of planarization layer, pixel defining layer and spacer layer or combination are multiplexed with protective layer.I.e. in shape
When at planarization layer, pixel defining layer or spacer layer, planarization layer, pixel above the corresponding cutting region of cutting line
Define layer or spacer layer there is no need to etching away, but remain using photoetching process and be multiplexed with protective layer, thus
It is increased without the technique that protective layer is prepared separately, preparation process flow can be simplified, saves production cost, improves production efficiency.
Such as the protective layer of the embodiment of the present invention can be the figure of independent multiplexing planarization layer, individually be multiplexed the figure of pixel defining layer
Shape, individually multiplexing spacer layer figure, can also be multiplexed planarization layer, pixel defining layer and spacer layer figure it
One or combination.Since planarization layer, pixel defining layer and spacer layer are all the film layers having in the prior art, in the reality of the present invention
The specific figure that these film layers are not provided in example is applied, the invention reside in be multiplexed these film layers as protective layer to absorb laser energy
Amount and release impact force, prevent edge film layer heated and are hit and crack and spread to viewing area, existing to solve
Cause cutting region film layer to easy to produce crackle because laser intensity is excessive in technology, the crackle inwardly conduct into viewing area and
The problem of influencing display.
Further, in above-mentioned display panel provided in an embodiment of the present invention, as shown in Fig. 2, display panel further includes
Be completely covered the barrier layer 02 of underlay substrate 01, barrier layer 02 be in order to improve surface attached power, barrier water oxygen at the same play every
The effect of hot antistatic；Display panel further includes being located at at least one layer that display area and neighboring area AA are covered on barrier layer 02
Film layer 10；Orthographic projection of the film layer 10 on underlay substrate 01 does not have crossover region with orthographic projection of the protective layer 07 on underlay substrate 01
Domain.But since barrier layer 02 is usually inorganic layer, very thin, when being cut using laser technology, barrier layer 02 is easy to
It cracks, precisely in order to preventing the generation of crackle, the protective layer 07 that the present invention is arranged can absorb laser energy and release is rushed
Power is hit, prevent barrier layer 02 heated and is hit and is cracked and spread to viewing area, to solve in the prior art because swashing
Luminous intensity is excessive and cutting region barrier layer 02 is caused to easy to produce crackle, which inwardly conducts into viewing area and influence to show
The problem of showing.
Further, crack propagation in order to prevent, in above-mentioned display panel provided in an embodiment of the present invention, such as Fig. 2 institutes
Show, the subregion of close protective layer 07 includes multiple independently arranged first grooves 001 in film layer 10.In this way when barrier layer 02
When cracking, first groove 001 can stop crack propagation.
