[specific embodiment]
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate the present invention with reference to additional schema Example.The direction term that the present invention is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outside", " side " Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to The limitation present invention.The similar unit of structure is to be given the same reference numerals in the figure.
It is referring to figure 3. the structural schematic diagram of display panel of the invention to 7, Fig. 3.
As shown in figure 3, display panel of the invention includes first substrate 20, the second substrate 10 and the first frame glue 12, go back It may include the second frame glue 11.
In conjunction with Fig. 4, the second substrate include viewing area 101, Liang Ge gate driving area 102 and two the first frame glue areas (with The position of first frame glue 12 is corresponding), wherein gate driving area 102 includes gate driving circuit and signal wire.Two grids Driving area 102 is located at the two sides of the viewing area 101.For example, in one embodiment, position is distinguished in gate driving area 102 In the left and right sides of viewing area 101.
Between the viewing area 101 and the gate driving area 102, the grid is driven in each first frame glue area Matcoveredn 13 is covered in dynamic area 102.Wherein the thickness of the protective layer 13 is located in preset range, for example protective layer 13 is upper Surface abuts first substrate 20.Since the thickness of protective layer 13 is located in preset range, gate driving area can be preferably protected 102。
In conjunction with Fig. 3 and 4, the first frame glue 12 is arranged between the first substrate 20 and the second substrate 10, and described First frame glue 12 is located at first frame glue area.Wherein first frame glue 12 in left side is located at the left side of viewing area 102;The of right side One frame glue 12 is located at the right side of viewing area 102.It should be understood that Fig. 3 is the gate driving area 102 and viewing area on right side in Fig. 4 101 structural schematic diagram.
As shown in figure 4, the end of first frame glue 12 is abutted with second frame glue 11.First frame described in two of them Glue 12 is respectively along the arrangement of the two sides of the second substrate 10 namely one of them first frame glue 12 along the one of the second substrate 10 Side arrangement.In one embodiment, when gate driving area 102 is located at the left and right sides of the second substrate 10,12 edge of the first frame glue at this time The width direction of the second substrate 10 is arranged, and the upper and lower end parts of the first frame glue 12 are abutted with the second frame glue 11.In another embodiment party In formula, when gate driving area 102 may be alternatively located at the upper and lower sides of the second substrate 10, the first frame glue 12 is along the length side of the second substrate 10 To arrangement, the left and right end portions of the first frame glue 12 are abutted with the second frame glue 11.
It will of course be understood that, the second substrate 10 can also only include a gate driving area 102 and first frame glue Area, gate driving area 102 is located at the left side or right side of the second substrate 10 at this time.First frame glue 12 is located at the viewing area 101 Left side or right side.Specific set-up mode is similar to Fig. 3.
Second frame glue 11 is arranged between the first substrate 20 and the second substrate 10, and second frame glue 11 In the outside in the gate driving area 102, namely the side far from viewing area 101, and close to the edge of the second substrate 10.Namely Second frame glue 11 is compared with the first frame glue 12 further from viewing area 101.As shown in figure 4, the second frame glue 11 is cyclic structure, it is looped around The outside of the gate driving area 102 and viewing area 101.
It should be understood that display panel of the invention can be liquid crystal display panel or organic light-emitting diode display Device.
The present invention also provides a kind of restorative procedures of above-mentioned display panel, specifically for the gate driving area to display panel It is repaired, this method comprises:
S101, first part is removed;
For example, as shown in figure 3, the first substrate 20 includes at least a first part 21 and second part 22, described the A part 21 is corresponding with the position in region in outside in first frame glue area, and the region in the outside in first frame glue area is remote From the viewing area 101;Namely the first part 21 covers the gate driving area 102.The second part 22 covers institute State viewing area 101 and first frame glue area.
As shown in figure 5, specifically, the first part 21 is cut away, only remaining second part 22.
S102, the removal protective layer, and the gate driving area is repaired;
For example, as shown in fig. 6, the protective layer 13 in the gate driving area 102 is removed, gate driving area 102 is naked It exposes outside.For example when signal wire breaks down, the signal wire in gate driving area 102 is detected and repaired.Certainly, if The gate driving circuit in gate driving area 102 breaks down, and can also repair to gate driving circuit.
S103, gate driving area after the reparation top make flatness layer.
For example, after the completion of reparation, as shown in fig. 7, the top production in the gate driving area 102 after the reparation is flat Layer 14, to protect to gate driving area 102, prevents its damage.
In one embodiment, the upper surface of the flatness layer 14 is flushed with the upper surface of the second part 22, so that The upper surface of display panel flushes.
Wherein, the flatness layer 14 is located at the top in the gate driving area 102 and second frame glue 11.Namely it is described Flatness layer 14 covers the gate driving area 102 and second frame glue 11.
In one embodiment, impaired in order to be better protected from gate driving area, the flatness layer 14 is damp proof insulation glue, It for example is luxuriant and rich with fragrance (tuffy) glue of tower.
Due to making protective layer in the top in gate driving area, and carry out gate driving area and viewing area using frame glue Isolation, when needing that gate driving area is tested and repaired, removes the substrate and protective layer above gate driving area, to it It is repaired, to reduce product yield, avoids scrap of the product, thereby reduce production cost.
The present invention also provides a kind of display devices comprising any one of the above display panel.
Restorative procedure, display panel and the device of display panel of the invention pass through the covering protection in gate driving area Layer, and frame glue is set between viewing area and gate driving area, thus when gate driving area occurs bad, convenient for being carried out to it It repairs, improves product yield, reduce production cost.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
