The utility model embodiment provides a kind of display base plate, comprising: substrate, the anode being set in turn on the substrate Layer and cathode layer.As shown in Figure 1, the cathode layer being set on substrate 10 include several mutually insulateds and be arranged in array first Electrode 21, the cabling 22 being electrically connected with each first electrode 21；From the electricity for the cabling 22 that different first electrodes 21 are electrically connected Resistance is consistent.Wherein, the substrate 10 includes first area 3 and second area 4, and first area 3 is located at the left side of substrate 10, and second Region 4 is located at the right side of substrate 10；In the first electrode 21 of first area 3, by sequence from left to right, with first row It the width for the cabling 22 that the first electrode 21 of A1, secondary series A2 and third column A3 are electrically connected and is equal in length；Positioned at In the first electrode 21 in two regions 4, by sequence from right to left, with first row A1 ', secondary series A2 ' and third column A3 ' first It the width for the cabling 22 that electrode 21 is electrically connected and is equal in length.

In order to make the cabling 22 being connected with the first electrode 21 of same a line be not take up excessive wiring space, and will be described Substrate 10 is divided into first area 3 and second area 4.The cabling 22 that first electrode 21 positioned at first area 3 is connected can be with The non-display area 2 in left side is extended to, the cabling 22 being connected positioned at the first electrode 21 of second area 4 can extend to right side Non-display area 2.Wherein, the directional terminologies such as " left side " and " right side " are the orientation put relative to the oled display substrate signal in attached drawing Come what is defined, it should be understood that, these directional terminologies are opposite concepts, they be used for relative to description and clarification, It can correspondingly be changed according to the variation in the orientation that oled display substrate is placed.

Herein, the size of first area 3 and second area 4 is not defined.In some embodiments, by substrate 10 The left area of middle line is set as first area 3, sets second area 4 for the right area of the middle line of substrate 10.

In some embodiments, in order to save wiring space and simplify wiring technique, between adjacent rows first electrode 21, The cabling 22 being connected with the first electrode 21 of same a line is arranged in parallel.

In the first electrode 21 of first area 3, by sequence from left to right, with first row A1, secondary series A2 and The width of cabling 22 and be equal in length that the first electrodes 21 of three column A3 are electrically connected.That is, as shown in Fig. 2, being located at first In the first electrode 21 in region 3, the cabling 22 that is electrically connected with the first electrode 21 of first row A1, secondary series A2 and third column A3 Width is respectively W1, W2 and W3, and W1=W2=W3.With 21 electricity of first electrode of first row A1, secondary series A2 and third column A3 The length of the cabling 22 of connection is respectively L1, L2 and L3, and L1=L2=L3.

Similarly, in the first electrode 21 of second area 4, by sequence from right to left, with first row A1 ', secondary series The set-up mode for the cabling 22 that the first electrode 21 of A2 ' and third column A3 ' is electrically connected is also in this way, details are not described herein. Since the resistance for the cabling 22 being electrically connected from different first electrodes 21 is consistent, in some embodiments, and it is located at the The width for the cabling 22 that first row A1 ', the secondary series A2 ' and third column A3 ' first electrode 21 in two regions 4 are electrically connected is equal to W1, length are equal to L1.

It should be noted that " consistent " in " resistance of cabling 22 is consistent " refers in the model for designing and making tolerance permission In enclosing, the resistance value of a plurality of cabling 22 is identical or approximately uniform.

In the utility model embodiment, each cabling 22 is electrically connected with a first electrode 21.

It is understood that since cathode layer includes several mutually insulateds and the first electrode 21 being arranged in array, When inputting common voltage to first electrode 21 by cabling 22, under the action of first electrode 21 and anode layer Anodic, drive Move the luminescent layer in organic material functional layer positioned there between carry out it is luminous, to realize display function.And works as and pass through When line 22 inputs touch drive signal to first electrode 21, first electrode 21 is used as touch control electrode, to know to position of touch Not.

That is, in the case where the oled display substrate is applied to display panel, when display panel is in display rank Duan Shi inputs common voltage to first electrode 21 by cabling 22, so that first electrode 21 and corresponding anode are formed Electric field, so that it is luminous to excite the luminescent layer between first electrode 21 and anode to carry out.When display panel is in the touch-control stage When, touch drive signal is inputted to first electrode 21 by cabling 22, and receive touch-control sensing signal, to send out according to capacitance Coordinate where the self-capacitance for changing determines position of touch.

In order to which individually to each 21 input signal of first electrode or reception signal, several gold can be formed on the substrate 10 Belong to lead, and every cabling 22 is made to be electrically connected (as shown in Figure 3) with a metal lead wire 30 of lower section by via hole.Based on this, By making metal lead wire 30 and touch-control driving chip (Touch Driver IC, TIC) 41 and display driver chip (Display Driver IC, DDI) 42 electrical connections, first electrode 21 can be made to receive the signal from TIC41 and DDI42, and by the touching of acquisition Control inductive signal feeds back to TIC41.

TIC41 and DDI42 can be independently arranged.In some embodiments, as shown in figure 3, DDI42 is directly arranged at The non-display area 2 of oled display substrate.TIC41 is set to flexible circuit board (Flexible Printed Circuit, FPC) On, and flexible circuit board is tied to the non-display area 2 of oled display substrate.

Certainly, TIC41 and DDI42 can also be integrated in a chip.Based on this, it need to only make metal lead wire 30 integrated with this Chip connection.

In some embodiments, when the oled display substrate is applied to display panel, as shown in figure 3, the display Panel further includes encapsulation cover plate 50.Wherein, encapsulation cover plate 50 can be cover-plate glass or be thinner package film layer.

The utility model embodiment provides a kind of oled display substrate, by making cathode layer include several mutually insulateds and being in The first electrode 21 of array arrangement, can make first electrode 21 also be multiplexed with touch control electrode, to realize embedded (Full completely In Cell, FIC) touch-control, structure is simple.On this basis, the cabling 22 by will be electrically connected from different first electrodes 21 Resistance be set as unanimously making the resistance value of cabling 22 itself, to by each cabling 22 to first electrode connected to it The signal of 21 inputs, and the influence for acquiring signal exported to TIC41 are identical.To by carrying out that resistance is waited to set to cabling 22 Meter reduces influence of the IR pressure drop (IR-Drop) as caused by 22 resistance difference of cabling to display and touch-control performance.

In some way of example, the material of the cathode layer is metal material.

Since metal has preferable ductility, when the oled display substrate is applied to flexible display apparatus, It can obtain preferably bending (Bending) effect.To solve in the prior art, using externally embedded type (on cell) In the case where touch-control structure, leads to not satisfaction bending since the electrode in the touch-control structure is made of transparent conductive material and want The defect asked.

On this basis, it can set opaque for anode layer, and relatively thin make cathode layer half for what the thickness of cathode layer was done It is transparent, so as to be based on microcavity effect, light exitance is improved in display.

In some way of example, any first electrode 21 and the cabling 22 being connected electrically are structure as a whole.That is, the One electrode 21 is arranged with 22 same layer of cabling, and first electrode 21 is electrically connected with cabling 22 without passing through via hole.

Based on this, by making cabling 22 extend to non-display area 2 (as shown in Figure 1) by viewing area 1, and in non-display area 2 Realization cabling 22 is electrically connected with metal lead wire 30, and the via hole that cabling 22 can be made to be electrically connected with metal lead wire 30 is located at non-display area 2。

On the one hand, relative to as shown in figure 4, making touch control electrode 61 by via hole and touch control electrode line 62 in 1 electricity of viewing area Connection, will lead to influence aperture opening ratio, the utility model embodiment can avoid this problem.On the other hand, when touch control electrode 61 passes through Via hole with touch control electrode line 62 when viewing area 1 is electrically connected, as shown in figure 5, if organic material functional layer is followed successively by from bottom to top Hole injection layer (HI) 631, hole transmission layer (HT) 632, the laying 633 for adjusting microcavity height, for improving hole Efficiency of transmission obtain buffer layer (HTEB) 634, luminescent layer (EML) 635 and electron transfer layer (ET) 636, then organic material function Each layer of ergosphere is both needed to will lead to yield reduction and increased costs by fining mask plate (FMM) preparation.And this is practical new In type example, since the via hole that cabling 22 is electrically connected with metal lead wire 30 is located at non-display area 2, as shown in fig. 6, in sun Organic material functional layer between pole 23 and first electrode 21 is followed successively by hole injection layer (HI) 631, hole transport from bottom to top Layer (HT) 632, the laying 633 for adjusting microcavity height obtain buffer layer (HTEB) for improving the efficiency of transmission in hole 634, in the case where luminescent layer (EML) 635 and electron transfer layer (ET) 636, it is only necessary to form luminescent layer 635 and lining using FMM Bed course 633, remaining each layer use open mask plate, so as to reduce the usage amount for using FMM, and then can be improved good Rate reduces cost of manufacture.

It should be noted that Fig. 5 and Fig. 6 are respectively to where red (R) luminescent layer 635 and green (G) luminescent layer 635 Microcavity height be adjusted for the explanation that carries out.When needs adjust the microcavity height where blue (B) luminescent layer 635 When section, above-mentioned laying 633 can also be formed in the corresponding position of microcavity where blue (B) luminescent layer 635.
