Please consult simultaneously Fig. 1 and Fig. 2.According to the present embodiment, the diameter of main gap 110 is less than the internal diameter of the depressed part 210c of auxiliary gap 210, and the internal diameter of depressed part 210c is preferably 2～3 times of diameter of main gap 110.For instance, when the diameter of main gap 110 was 6～8 microns (micrometer, μ m), the internal diameter of the depressed part 210c of auxiliary gap 210 can be 12～24 microns.Simultaneously, the height of main gap 110 is greater than the degree of depth of the depressed part 210c of auxiliary gap 210, and the degree of depth of depressed part 210c can be 0.5～0.8 times of height of main gap 110.For instance, when the height of main gap 110 was 3 microns, the degree of depth of the depressed part 210c of auxiliary gap 210 can be 1.5～2.4 microns.In addition, the height of main gap 110 is less than the liquid crystal layer gap.Quantity that it should be noted that in addition main gap 110 can be less than or equal to the quantity of auxiliary gap 210, also can be more than or equal to the quantity (being shown in Fig. 6) of auxiliary gap 210.For instance, in the present embodiment on the first bendable substrate 100 density of main gap 110 be 0.15%, but on the second bendable substrate 200, the density of auxiliary gap 210 is 1.37%, but is not limited to this.
See also Fig. 3.Next, the first bendable substrate 100 and the second bendable substrate 200 are carried out packing engineering.At first form frame glue 120 around the first bendable substrate 100.Next, carry out the Liquid crystal pour engineering, inject liquid crystal LC on the first bendable substrate 100.In the present embodiment, the Liquid crystal pour engineering can be liquid crystal drip-injection method (one drop fill, ODF), but not as limit.In addition, if the display medium that is formed between the first bendable substrate 100 and the second bendable substrate 200 is not liquid crystal material, the present embodiment also is not limited to above-mentioned Liquid crystal pour engineering.It should be noted that in addition, because auxiliary gap 210 on the second bendable substrate 200 has tube-in-tube structure, therefore when injecting liquid crystal, liquid crystal LC may be injected in the depressed part 210c of auxiliary gap 210, and then affect substrate to group after, may produce bubble in liquid crystal and cause display brightness inhomogeneous (mura).Therefore, in the present embodiment, the Liquid crystal pour engineering instils liquid crystal LC to the first bendable substrate 100 with main gap 110.
See also Fig. 4 and Fig. 5.Inject liquid crystal LC on the first bendable substrate 100 after, aim at the bendable substrate 100 of pressing first and the second bendable substrate 200, main gap 110 is inserted in respectively in the depressed part 210c of corresponding auxiliary gap 210, and is surrounded by corresponding auxiliary gap 210.Subsequently frame glue 120 is carried out hardening project, frame glue 120 is engaged the first bendable substrate 100 with the second bendable substrate 200.Next as shown in Figure 5, remove the first bearing substrate 102 and the second bearing substrate 202, complete the making of flexible display 10.It should be noted that each main gap 110 is inserted in respectively in the depressed part 210c of corresponding auxiliary gap 210 when assembling the first bendable substrate 100 and the second bendable substrate 200.Because the density of auxiliary gap 210 is higher, in other words the quantity of auxiliary gap 210 is more than or equal to the quantity of main gap 110, therefore each main gap 110 must have auxiliary gap 210 of a correspondence, and obtains a plurality of paired spacer 310(paired spacer between the first bendable substrate 110 and the second bendable substrate 210).But for auxiliary gap 210, namely may as Fig. 4 and shown in Figure 5, have part auxiliary gap 210 and not correspond to main gap 110.
It should be noted that in addition, in each forms spacer 310, due to the internal diameter of the depressed part 210c of auxiliary gap 210 as previously mentioned greater than the diameter of main gap 110, the difficulty in the time of therefore can reducing the first bendable substrate 100 and the second bendable substrate 200 contraposition.In addition, due to the height of main gap 110 width less than the liquid crystal layer gap, therefore after the assembling of completing the first bendable substrate 100 and the second bendable substrate 200, main gap 110 does not contact the second bendable substrate 200.
The flexible display 10 that provides according to the present embodiment, be provided with on the surface of the first bendable substrate 100 with respect to the second bendable substrate 200 highly higher, diameter is less, negligible amounts and comparatively soft tough main gap 110 of material, and each main gap 110 has column structure.Be provided with auxiliary gap 210 highly lower, that quantity is more and material is comparatively hard on the second bendable substrate 200 of flexible display 10, and auxiliary gap 210 has respectively a tube-in-tube structure: its have the bottom 210a, around the sidewall 210b of bottom 210a and the depressed part 210c that is defined by bottom 210b and sidewall 21b.It should be noted that the internal diameter of depressed part 210c greater than the diameter of main gap 110, but the degree of depth of depressed part 210c is less than the height of main gap 110.In other words, all be formed with the spacer that is fixed thereon on two bendable substrates of the flexible display 10 that the present embodiment provides, and the spacer on same bendable substrate has identical height, but the spacer height on different bendable substrate is not identical.As shown in Figure 5, according to the flexible display 10 that the present embodiment provides, under the state that applies without external force, main gap 110 does not contact the second bendable substrate 200, and in like manner auxiliary gap 210 does not contact the first bendable substrate 100.Each main gap 110 is inserted in respectively in the depressed part 210c of corresponding auxiliary gap 210, and this moment, the clearance height H between auxiliary gap son 210 and main gap 110 can be in order to the permissible range (liquid crystal margin) of improving the liquid crystal loading.
See also in addition Fig. 6, Fig. 6 is the schematic diagram of a change type of flexible display provided by the present invention.According to this change type, the diameter of main gap 110 is still less than the internal diameter of the depressed part 210c of auxiliary gap 210, and the material of main gap 110 and auxiliary gap 210 can be identical or different.But quantity that it should be noted that main gap 110 can be more than or equal to the quantity of auxiliary gap 210.In this change type, the quantity of main gap 110 can equate with auxiliary gap 210 for instance.Briefly, according to the present embodiment and change type thereof, the quantity of main gap 110 can be according to the different product demand and greater than, be equal to or less than the quantity of auxiliary gap 210.
See also Fig. 7, the schematic diagram the when flexible display that Fig. 7 provides for the present embodiment is subjected to external force generation deflection.As previously mentioned, because main gap that the present embodiment provides son 110 is individually fixed on the first bendable substrate 100 and the second bendable substrate 200 with auxiliary gap 210, therefore no matter be that external force P1 makes flexible display 10 deflections or when temperature sharply changes, all can avoid rete or display element on spacer 110, the 210 bendable substrates 100 of scratch, 200 applying.should be noted in addition, when external force P1 puts on flexible display 10, make it as shown in Figure 7 during deflection, the liquid crystal layer gap of flexible display 10 may be squeezed and narrow down, main gap 110 conflicts this moment are to the bottom of the depressed part 210c of auxiliary gap 210, and the liquid crystal layer gap of flexural center point is mainly together kept with auxiliary gap 210 by main gap 110, therefore the first bendable substrate 100 and the second bendable substrate 200 of flexible display 10 still can have uniform gap, that is to say that applying of 110 couples of external force P1 of main gap has buffering effect.As previously mentioned, because main gap 110 is more resilient photoresist, therefore flexible display 10 can have better restoring force when pressed by external force P1.In addition as previously mentioned, when external force P1 puts on flexible display 10, except the variation in liquid crystal layer gap, also produce shearing between two flexible substrates 100,200 of flexible display 10.It should be noted that, because each forms the internal diameter of the depressed part 210c of auxiliary gap 210 of spacer 310 diameter greater than main gap 110, therefore can limit main gap 110 is subject to shearing action and the scope of displacement, and then reaches the scope of controlling two bendable substrates 100,200 displacements.In other words, the paired spacer 310 that provides of the present embodiment can improve the fiduciary level of flexible display 10 more.
Next see also Fig. 8, the schematic diagram the when flexible display that Fig. 8 provides for the present embodiment is subjected to another external force and produces deflection, and it should be noted that external force P2 in Fig. 8 is greater than external force P1.When putting on flexible display 10, larger external force P2 make it as shown in Figure 8 more during deflection, the liquid crystal layer gap of flexible display 10 becomes narrower because continuing to be squeezed, more resilient main gap 110 conflicts this moment are to bottom and the generation deformation of the depressed part 210c of auxiliary gap 210, the sidewall 210b top of auxiliary gap 210 first flexible base plate 100 of conflicting is therefore the liquid crystal layer gap of flexural center point is mainly kept by auxiliary gap 210.Therefore the first bendable substrate 100 and the second bendable substrate 200 of flexible display 10 still can have uniform distance, that is to say that pressing of larger external force P2 still had buffering effect.As previously mentioned, because auxiliary gap son 210 is harder photoresist, therefore the pressurized distance in the time of can controlling flexible display 10 and be subject to external force P2 and press increases the resistance to pressure of flexible display 10 whereby.In addition, comprise auxiliary gap 210 in the auxiliary gap son 210 that do not correspond to main gap 110 and spacer 310 in pairs due to the sub-210(of auxiliary gap) quantity more, therefore can guarantee that flexible display 10 can the breakage because of external force P2.In addition as previously mentioned, when external force P2 put on flexible display 10, the deformation of flexible display 10 caused the scope of two flexible substrates 100,200 displacements, still can control by paired spacer 310 as previously mentioned.
See also at last Fig. 9 to Figure 10, Fig. 9 to Figure 10 is the schematic diagram of the change type of main gap provided by the present invention and auxiliary gap.At first should be noted, in Fig. 9 to Figure 10, main gap and auxiliary gap only be shown, but the personage Ying Zhi Fig. 9 that is familiar with this technical field extremely these change types shown in Figure 10 can be integrated in easily in the method for above-mentioned making flexible display.As shown in Figure 9, main gap 110 that this change type provides can have cylindrical shape, and the depressed part 210c that auxiliary gap 210 has bottom 210a, sidewall 210b and defined by bottom 210a and sidewall 210b.The more important thing is, in this change type, the sidewall 210b of auxiliary gap 210 also has pressure relief opening 210d, the design of this pressure relief opening 210d can be lowered gas and the impact of liquid crystal LC when the first bendable substrate 100 is aimed at pressing with the second bendable substrate 200, can improve the elasticity of auxiliary gap 210 simultaneously.See also Figure 10, change type illustrated in fig. 10 is inserted main gap 110 and auxiliary gap 210.As shown in figure 10, main gap 110 of this change type comprises rounding vertebra post shapes wide at the top and narrow at the bottom, the depressed part 210c of auxiliary gap 210 is up-narrow and down-wide, therefore main gap 110 and auxiliary gap 210 more driving fit each other when involutory, therefore flexible display 10 is when being subject to external force, spacer 310 can improve the control to the first bendable substrate 100 and the second bendable substrate 200 displacements in pairs.In this change type, also pressure relief opening 210d can be set on the sidewall 210b of auxiliary gap 210 in addition.
Indulge the above, flexible display provided by the present invention and preparation method thereof, in forming respectively fixing main gap and auxiliary gap on the first bendable substrate with on the second bendable substrate, increase the permissible range of liquid crystal loading by the clearance height between main gap and auxiliary gap, and avoid the spacer rubbed substrate to cause the destruction of rete on substrate.The more important thing is, utilization of the present invention has the distance that elastic force and highly higher main gap are kept liquid crystal layer gap after the flexible display pressurized, increases the elasticity of recovering after the flexible display pressurized.Utilize simultaneously the pressurized distance of comparatively hard and highly lower auxiliary gap restriction flexible display, guarantee that flexible display can be not damaged because being subject to larger external force deflection.In addition, the scope of two relative flexible base plate displacements when the present invention also controls the flexible display deflection by main gap with the formed paired spacer of part auxiliary gap is therefore can more improve the durability of flexible display.
