Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, attached below with reference in the embodiment of the present invention Figure, by detailed description of the invention, is fully described by technical scheme.Obviously, described embodiment is the present invention A part of embodiment rather than whole embodiments, based on embodiments of the invention, those of ordinary skill in the art are not doing The every other embodiment obtained on the premise of going out creative work, within each falling within protection scope of the present invention.
Fig. 1 a is the side-looking structural representation of a kind of touch control display apparatus that the embodiment of the present invention provides.As shown in Figure 1a, Touch control display apparatus 100 includes flexible base board 110, the organic luminous layer 120 being arranged on flexible base board 110, is arranged at organic Luminescent layer 120 deviates from the sealant 130 of flexible base board 110 side, is arranged at sealant 130 and deviates from organic luminous layer 120 side Touch control electrode layer 150, fluid protection layer 140, fluid protection layer 140 be arranged at sealant 130 and touch control electrode layer 150 it Between.
It should be noted that sealant 130 is for sealing organic luminous layer 120, need directly and organic light emission Layer 120 contact, additionally, touch control electrode layer 150 is arranged at organic luminous layer 120 and deviates from the one of flexible base board 110 in the present embodiment Side, is therefore arranged at sealant by the fluid protection layer 140 being used for alleviating touch control electrode layer 150 and organic luminous layer 120 stress Between 130 and touch control electrode layer 150.
The technical scheme that the present embodiment provides, by the touch control electrode layer 150 in touch control display apparatus 100 and sealant Arranging fluid protection layer 140 between 130, when making touch control display apparatus 100 be bent, fluid bulk can be to fluid protection layer The part flowing that in 120, position is relatively low, makes the segment thickness that in fluid protection layer 120, position is relatively low more than position phase To higher part, and then reduce the touch control electrode layer 150 away from flexural center or the crooked radian of organic luminous layer 120, Reach to alleviate stress suffered by touch control electrode layer 150 or organic luminous layer 120, reduce the beneficial effect of device failure rate.
Fig. 1 b is the cross-sectional view of dotted line AB along Fig. 1 a.As shown in Figure 1 b, fluid protection layer 140 can include Fluid bulk 141 and enclose the restriction frame 142 being located at fluid bulk 141 periphery.It should be noted that fluid bulk 141 has Mobility, therefore uses restriction frame 142 fluid bulk 141 to be limited in specific region.Also, it should be noted the present embodiment To limiting the size of frame 142 and arranging position and be not specifically limited, limiting outer 142 edges of frame can be with flexible base board 110 Outer surface flushes (as shown in Figure 1a), it is also possible to inside flexible base board 110 (as illustrated in figure 1 c).For the previous case, limit Determining the size size equal to flexible base board 110 of frame 142, for latter event, limit frame 142 is smaller in size than flexible base board The size of 110.
Optionally, fluid bulk 141 uses transparent material to be formed.So that the display performance of touch control display apparatus 100 will not It is affected because of the setting of fluid protection layer 140.Exemplary, fluid bulk 141 can be long-chain hydrocarbon system polymer, gather Any one in butylene, polyisobutylene, silicone, liquid synthetic rubber and liquid paraffin.
In fig 1 a, organic luminous layer 120 include switching device layer 122 and be arranged on switching device layer 122 send out Optical diode layer 121.
It should be noted that switching device layer 122 includes multiple switching device, each switching device and a pixel cell It is correspondingly arranged, for closing under the effect driving signal or disconnecting, to control the display of respective pixel unit.Exemplary, Switching device is generally thin film transistor (TFT), then switching device layer 122 includes multiple thin film transistor (TFT)s of array arrangement.Merit attention , thin film transistor (TFT) in switching device layer 122 and for driving scan line or the number of signal for thin film transistor (TFT) transmission Generally use metal material to be formed according to line, therefore, the grid of thin film transistor (TFT), source electrode, drain electrode and semiconductor layer, and scan line It is inorganic film with data wire, and thickness is less, cause the stress that can bear less.Similar, touch control electrode layer 150 is also For the inorganic film that thickness is less, it is possible to the stress born is the least.And in actual use, as flexible touch-control A part for display device 100, touch control electrode layer 150 and switching device layer 122 inevitably bend touch-control user It is bent during display device 100.
Fig. 1 d is the structural representation in Fig. 1 a after touch control display apparatus bending.As shown in Figure 1 d, touch control display apparatus 100 After bending, the left and right sides is less than centre position, and now, the fluid bulk in fluid protection layer 140 has mobility, can be to position The flowing of the relatively low left and right sides, concrete, the flow direction of fluid bulk is as shown in the arrow in Fig. 1 d, and at the present embodiment In, the restriction frame of fluid protection layer 140 uses elastomeric material to be formed, in order to fluid protection layer 140 each several part thickness can be with liquid The distribution situation of body body carries out the adjustment of correspondence.As shown in Figure 1 d, the left and right sides of the fluid protection layer 140 after bending is thicker Middle relatively thin, the flexural center under bend mode shown in Fig. 1 d is positioned on the downside of flexible base board 110, in fluid protection layer 140 structure After being changed with bending situation, the crooked radian away from the touch control electrode layer 150 of flexural center reduces so that relative to not having The situation of fluid protection layer 140, when touch control display apparatus 100 carries out same degree bending, suffered by touch control electrode layer 150 Stress reduce, reduce the damage probability of touch control electrode layer 150.Exemplary, select the organic luminous layer 120 in Fig. 1 d to lean on Place, the side curved surface of nearly flexible base board 110 is neutral surface, due to touch control electrode layer 150 under the effect of fluid protection layer 140 The absolute stress born reduces, and therefore, touch control electrode layer 150 is also corresponding relative to the stress value of neutral surface to be reduced.Need explanation , under other bend mode, fluid protection layer 140 also is able to play alleviates the effect of stress suffered by organic luminous layer 120, Concrete alleviation principle is identical with above-mentioned situation, does not repeats them here.
In fig 1 a, sealant 130 can be at least one organic layer and the stepped construction of at least one inorganic layer formation, its In, stepped construction can be two layers, three layers or multilamellar.Use the sealing effectiveness of the sealant 130 that above-mentioned stepped construction formed More preferably, it is possible to be effectively isolated water and air, and then beneficially increase and the touch control display apparatus 100 of lifetime of LED is good The holding of good performance.
