The embodiment of the present invention provides a kind of display base plate.Fig. 1 is the structural representation that a kind of display base plate of providing of the embodiment of the present invention and principal post shape dottle pin body combine.As shown in Figure 1, described display base plate comprises: substrate 11; Be arranged at least one conductive layer 12 on described substrate 11; Be arranged on the multiple patterned piezoelectric layer 13 on described conductive layer 12; Be arranged on many first wires 14 on described patterned piezoelectric layer 13; Multiple principal post shape dottle pin body 15 (the Main Post Spacers corresponding with described first wire 14, be called for short MainPS), when touch-control occurs, described principal post shape dottle pin body 15 changes into electric signal to the pressure of described patterned piezoelectric layer 13 through described patterned piezoelectric layer 13 and is derived by described first wire 14.
It should be noted that, in embodiments of the present invention, all using from substrate 11 to the direction of conductive layer 12 as direction upward, contrary direction is then as direction down, wherein top or below are only the descriptions to residing orientation, direct contact can be referred to, also can refer to indirect contact, restriction is not formed to concrete structure.
Particularly, an each principal post shape dottle pin body 15 corresponding coordinate corresponding with the first wire in display base plate, and each patterned piezoelectric layer 13 can be arranged at least one the first wires 14, namely each patterned piezoelectric layer 13 can be corresponding with at least one principal post shape dottle pin body 15.By the patterned piezoelectric layer 13 arranging conductive layer 12 and be located thereon in display base plate, wherein, conductive layer 12 can be applied in a fixing reference voltage (this reference voltage can be selected as required), when touch-control occurs, principal post shape dottle pin body 15 can extrude patterned piezoelectric layer 13, causing (can for directly to contact with principal post shape dottle pin body 15 contact position, also can for indirect contact) patterned piezoelectric layer 13 there is deformation, under the effect of the voltage on conductive layer 12, the surface that patterned piezoelectric layer 13 contacts with conductive layer 12 and the surperficial coating-forming voltage that contacts with principal post shape dottle pin body 15 poor, namely principal post shape dottle pin body 15 has been changed into electric signal to its applied pressure by patterned piezoelectric layer 13, the electric signal obtained is derived by the first wire 14, again by processing electric signal, the coordinate of the principal post shape dottle pin body 15 of touch-control nidus can be obtained, thus the coordinate of position of touch can be determined.
As mentioned above, be provided with the display base plate of conductive layer 12 and patterned piezoelectric layer 13, when touch-control occurs, do not need to apply driving voltage to patterned piezoelectric layer 13 to drive, patterned piezoelectric layer 13 self just can produce electric signal, with capacitance type touch-control panel in order to realize compared with touch controllable function needs ceaselessly to scan touch-control drive electrode or touch control electrode, technical scheme of the present invention can reduce power consumption when realizing touch controllable function, realizes the effect of power saving.
In FIG, display base plate also comprises black matrix" 16 and color blocking layer 17, wherein, black matrix" 16 arranges on the substrate 11, color blocking layer 17 is arranged on black matrix", due to the basic display structure that black matrix" and color blocking layer are color membrane substrates, the display base plate therefore shown in Fig. 1 is color membrane substrates.After setting gradually black matrix" 16 and color blocking layer 17 on the substrate 11, conductive layer 12 is arranged on color blocking layer 17, then on conductive layer 12, arranges patterned piezoelectric layer 13, and arranges the first wire 14 on described patterned piezoelectric layer 13.
In embodiments of the present invention, patterned piezoelectric layer 13 can comprise polymkeric substance, monomer, Photoepolymerizationinitiater initiater, solvent and piezoelectric.Preferably, described piezoelectric is piezopolymer, such as segregation fluorothene etc., because this kind of piezoelectric is soft, processability is good, shock-resistant, and the piezoelectric voltage constant of this type of material is high, therefore, prepared piezoelectric layer 13 can improve the sensitivity of touch-control.
Fig. 2 is a kind of schematic top plan view of Fig. 1.As depicted in figs. 1 and 2, the first end of described first wire 14 is arranged between described principal post shape dottle pin body 15 and described patterned piezoelectric layer 13, the i.e. electric signal that produces when touch-control occurs for receiving patterned piezoelectric layer 13 of the first end of the first wire 14, and the second end of the first wire 14 is used for exporting telecommunication number.Because patterned piezoelectric layer 13 the larger position of deformation ratio occurs for this patterned piezoelectric layer 13 and principal post shape dottle pin body 15 contact position (patterned piezoelectric layer 13 and principal post shape dottle pin body 15 are indirect contact in FIG), therefore higher in the intensity of the electric signal of this contact position patterned piezoelectric layer 13 generation when touch-control occurs.And the first wire 14 is for deriving this electric signal to process the coordinate determining position of touch to this electric signal, therefore, the intensity of the electric signal that the first wire 14 can be derived is higher, is more conducive to the accuracy and precision improving determined position of touch.Because the electrical signal intensity produced in patterned piezoelectric layer 13 and principal post shape dottle pin body 15 contact position when touch-control occurs is higher, therefore, the first end of the first wire 14 is arranged between principal post shape dottle pin body 15 and patterned piezoelectric layer 13, such first wire 14 can derive the higher electric signal of intensity, thus can improve the accuracy and precision of determined position of touch.
As shown in Figure 1, the shape of the first end of the first wire 14 is identical with size with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11 with size.The electric signal produced at patterned piezoelectric layer 13 and principal post shape dottle pin body 15 contact position when touch-control occurs so almost can all be derived by the first wire 14, thus can improve the accuracy and precision of determined position of touch.
Except the shape of the first end of the first wire 14 shown in Fig. 1 is except size is identical with size with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11, as shown in Figure 3, the shape of the first end of the first wire 14 is identical with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11, but the size of the first end of the first wire 14 is less than the size of principal post shape dottle pin body 15 orthogonal projection on the substrate 11.Because in Fig. 3, the size of the first end of the first wire 14 is less than the size of the first end of the first wire 14 in Fig. 3, therefore, in Fig. 1 the electric signal that the first wire 14 exports strength ratio Fig. 3 in the electrical signal intensity that exports of the first wire 14 want high.
Because the vertical view of Fig. 3 is identical with the vertical view of Fig. 1, therefore about the vertical view of Fig. 3, specifically please refer to Fig. 2 and relevant description thereof, do not repeat them here.
Except Fig. 1 and Fig. 3, as shown in Figure 4, the shape of the first end of the first wire 14 is identical with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11, but the size of the first end of the first wire 14 is greater than the size of principal post shape dottle pin body 15 orthogonal projection on the substrate 11.Because electric signal mainly produces patterned piezoelectric layer 13 and principal post shape dottle pin body 15 contact position (patterned piezoelectric layer 13 and principal post shape dottle pin body 15 are indirect contact in the diagram), therefore, although the size of the first end of the first wire 14 is larger than the size of the first end of the first wire 14 in Fig. 1 in Fig. 4, but in the first wire 14 and Fig. 1, the intensity of the electric signal that the first wire 14 exports is almost equal in Fig. 4.
Fig. 5 is a kind of schematic top plan view of Fig. 4.As shown in Figure 5, can more clearly see, the shape of the first end of the first wire 14 is identical with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11, and the size of the first end of the first wire 14 is greater than the size of principal post shape dottle pin body 15 orthogonal projection on the substrate 11.It should be noted that, in above-mentioned each figure, the shape of the first end of the first wire 14 is identical with the shape of principal post shape dottle pin body 15 orthogonal projection on the substrate 11, but, in other concrete example, the shape of the first end of the first wire also can not be identical with the shape of the orthogonal projection of principal post shape dottle pin body on substrate, in this no limit.
The first end that above-mentioned Fig. 1 to Fig. 5 gives the first wire is arranged on some the concrete examples between principal post shape dottle pin body and patterned piezoelectric layer.In another specific example, as shown in Figure 6, the first wire 14 is arranged on principal post shape dottle pin body 15 periphery, and the first wire 14 is being parallel to the bee-line A of orientation substrate X to principal post shape dottle pin body 15 surface in predeterminable range.Fig. 7 is a kind of schematic top plan view of Fig. 6.Also can see from Fig. 7, the first wire 14 is arranged on principal post shape dottle pin body 15 periphery, and the first wire 14 is being parallel to the bee-line A of orientation substrate X to principal post shape dottle pin body 15 surface in predeterminable range.
Because electric signal when touch-control occurs mainly produces patterned piezoelectric layer 13 and principal post shape dottle pin body 15 contact position (patterned piezoelectric layer 13 and principal post shape dottle pin body 15 are for directly contacting in figure 6 and figure 7), therefore, if the first wire 14 is to be parallel to orientation substrate X less to the bee-line A on principal post shape dottle pin body 15 surface, the intensity of the electric signal that the first wire 14 exports is higher, is also more conducive to the accuracy and precision improving determined position of touch.But the power of the electric signal that patterned piezoelectric layer 13 produces when touch-control occurs is relevant with the thickness of described patterned piezoelectric layer 13, and patterned piezoelectric layer 13 is thicker, then the electric signal produced when touch-control occurs is stronger, otherwise more weak.Therefore, for Fig. 6 and display base plate illustrated in fig. 7, in order to ensure the intensity of the electric signal that the first wire 14 exports, be preferably the half that predeterminable range is not more than patterned piezoelectric layer 13 thickness.By predeterminable range being elected as the half being not more than patterned piezoelectric layer 13 thickness, the intensity of the electric signal that the first wire 14 is derived can be ensured when touch-control occurs like this, thus can the accuracy and precision of determined position of touch.
As mentioned above, patterned piezoelectric layer 13 is thicker, and when touch-control occurs, the electric signal that patterned piezoelectric layer 13 produces is stronger.But the thickness of patterned piezoelectric layer 13 increases, not only can increase thickness and the weight of display base plate, but also the display effect of display base plate can be affected, Given this, in embodiments of the present invention, being preferably patterned piezoelectric layer 13 thickness can be 1 μm to 3 μm.But in actual design, can select the thickness of patterned piezoelectric layer 13 with design as required, its thickness also can be other values beyond above-mentioned scope, in this no limit.
In above-mentioned Fig. 1 to display base plate illustrated in fig. 7, each patterned piezoelectric layer arranges first wire, this is only some the concrete examples arranging the first wire on patterned piezoelectric layer, in other concrete example, many first wires also can be set at each patterned piezoelectric layer, correspondingly many corresponding multiple principal post shape dottle pin bodies of the first wire.Such as, as shown in Figure 8, each patterned piezoelectric layer 13 is provided with two first wires 14 and two corresponding two principal post shape dottle pin bodies 15 of the first wire 14, and the first end of every bar first wire 14 is between the principal post shape dottle pin body 15 corresponding with it and patterned piezoelectric layer 13, the size and shape of the first end of every bar first wire 14 is identical with the size and shape of corresponding principal post shape dottle pin body 15 orthogonal projection on the substrate 11.Fig. 9 is a kind of schematic top plan view of Fig. 8.Can be clear that from Fig. 9, each patterned piezoelectric layer 13 is provided with two first wires 14, and two corresponding two principal post shape dottle pin bodies 15 of the first wire 14, and the first end of every bar first wire 14 is between the principal post shape dottle pin body 15 corresponding with it and patterned piezoelectric layer 13, its second end is used for the exporting telecommunication number when touch-control occurs.
