Step S230:It is at least one layer of public in being formed on substrate 110 using shared mask plate 200 and the first mask plate 300 Pattern layer 130 so that at least one layer of common patterns layer 130 is not weighed with upright projection of the multiple spacers 120 on substrate 110 It is folded.The pattern that mask plate 200 defines at least one layer of common patterns layer 130 is shared, the first mask plate 300 defines spacer 120 Pattern.
Specifically, common mask plate 200 includes public open region 201 and public shading region 202.Public open region 201 Define the pattern of common patterns layer 130.First mask plate 300 and common mask plate 200 are overlapped, the first shading region 302 is in base Upright projection on plate 110 is located at public open region 201 in the upright projection on substrate 110, so that common patterns layer 130 In vapor deposition, 120 pattern of spacer is covered, to which common patterns layer 130 will not be formed on spacer 120.
It is similar with previous embodiment, using step shown in fig. 5, it can also make display panel as shown in Figure 2 so that Common patterns layer 130 will not be formed on gap 120, to which when display panel receives lash space 120 and damages, water oxygen will not Enter display panel between spacer 120 and common patterns layer 130.
Fig. 7 shows the schematic diagram of the display panel according to further embodiment of this invention.Display panel shown in Fig. 7 includes Viewing area 101 and non-display area 102 around viewing area.To show image and video, non-display area 102 can for viewing area 101 Selection of land is used for line arrangement.There are multiple pixels 140 in viewing area 101.Fig. 1 or Fig. 5 institutes can also be used in display panel shown in Fig. 7 The production method shown is made, and further includes in above-mentioned steps S120/ steps S220:It is multiple in being formed in viewing area 101 First spacer 121, and form the second spacer 122 around viewing area 101 in non-display area 102.So so that be located at base Spacer 120 on plate 110 includes multiple first spacers 121 in viewing area 101 and between the second of viewing area 101 Gap 122.The height H (such as Fig. 9) of second spacer 122 is 1 to 2 micron, and the width W of the second spacer 122 is 100 to 200 Micron.In the case where display panel processing procedure allows, the second spacer width increases, better to the iris action of water oxygen.As a result, In the embodiment shown in fig. 7, the second spacer 122 further can prevent water oxygen from invading in follow-up encapsulation, promote encapsulation Effect.
The display panel of further embodiment of this invention is described with reference to Fig. 7 to Fig. 9.Fig. 7 is shown according to the present invention again The schematic diagram of the display panel of one embodiment.Fig. 8 shows showing for the cover board of the display panel according to further embodiment of this invention It is intended to.Fig. 9 shows the sectional view of the display panel according to further embodiment of this invention.
In this example it is shown that the fabrication steps of panel, in addition to utilizing making side shown in Fig. 1 or Fig. 5 (in conjunction with Fig. 7) Method is made so that display panel includes substrate 110, positioned at the multiple spacers in the side of the substrate (including viewing area 101 Interior multiple first spacers 121 and the second spacer 122 around viewing area 101) and formed positioned at substrate 110 multiple The side at least one layer common patterns layer 130 of spacer, at least one layer of common patterns layer 130 is with multiple spacers in substrate 110 On upright projection be not overlapped, further include following steps:
Step 1:One cover board 150 is provided.
Step 2:In cover board 150 relative to the side formation protective layer 152 of substrate 110 and around the glass of protective layer 152 Material 151.
Step 3:Cover board 150 is set to form the side and the one of the formation spacer of substrate 110 of protective layer 152 and frit 151 Side is opposite, presses cover board 150 and substrate 110.Protective layer 151 corresponds to viewing area 101 in the upright projection on substrate 110, Gap (may include the first spacer 121 and the second spacer 122) is in contact with protective layer 151.Optionally, the spacer Adhesion range 10-50N/mm.Frit 152 is located at non-display area 102 in the upright projection on substrate 110, and around display Area 101.Optionally, the second spacer 122 is between frit 152 and viewing area 101.
Wherein, protective layer 152 can be made of epoxy resin.Epoxy resin adhesion is strong, mechanical strength is high, solidification temperature Width, shrinking percentage is small and light transmission rate is high.Protective layer 152 can be formed in the side of cover board 150 by modes such as silk-screen printings.
Step 4:Utilize laser curing frit 152.
Step 5:Heat cure is carried out to protective layer 151.
Above-mentioned steps 4 and step 5 can and non-sequential execution, such as step 5 can be first carried out and execute step 4 again.On in addition, Stating Fig. 1 or shown in fig. 5 production methods can carry out before above-mentioned steps 1, can also between above-mentioned steps 2 and step 3 into Row.Optionally, if making multiple display panels simultaneously, after the above procedure, it may also include the cutting step to display panel.
The display panel made through the above steps has resistance to hitting property.Protective layer 151 under the action of heat cure with substrate 110 spacer (the first spacer 121, and optionally the second spacer 122) is connected.It is act as relative to spacer before Maintain substrate 110 with for 150 gap homogeneity of cover board and support cover board 150, such combination can play good impact The effect of stress storage.When display panel can be stored a big chunk impact stress by collision time gap, hit to reduce The damage to display element and frit 152 is hit, and then significantly improves that display panel is resistance to hit performance.Further, since on spacer Common patterns layer is not deposited, therefore display panel can avoid aqueous vapor when being caused spacer crushing by crushing from spacer and public affairs Intrusion causes pixel to invaginate between pattern layer altogether.
Further, increase the second spacer 122 due to around the viewing area of substrate 110 101 more, with cover board After 150 protective layer 150 bonds, it is equivalent to and has been further added by one layer of aqueous vapor barrier layer in the encapsulation internal layer of frit 152, thus into one Step prevents water oxygen from invading, and promotes packaging effect.
