The embodiment of the present disclosure is described in detail with reference to the accompanying drawing, but the disclosure is not limited to these specifically in fact Apply example.

Figure 1A is a kind of floor map for touch-control display panel that one embodiment of the disclosure provides, and Figure 1B is the disclosure one The floor map for another touch-control display panel that embodiment provides, Fig. 2 are another touching that one embodiment of the disclosure provides The floor map of display panel is controlled, Fig. 3 is a kind of touch control electrode row for touch-control display panel that one embodiment of the disclosure provides Cloth schematic diagram.It should be noted that data line 16, which is adopted, to be represented by dashed line in Figure 1A, Figure 1B and Fig. 2, and touch-control line 15 uses Solid line indicates.

For example, as shown in Figure 1A, the touch-control display panel that the embodiment of the present disclosure provides includes substrate 38 and is arranged in substrate Multiple sub-pixel groups 10, multiple data lines 16, multiple touch control electrodes 20 and a plurality of touch-control line 15 on 38.Each sub-pixel group 10 Including being located at in a line and multiple sub-pixels of a data line 16 are shared, data line 16 is configured to same sub-pixel group 10 In multiple sub-pixels provide data-signal.For example, multiple touch control electrodes 20 are electrically connected with a plurality of touch-control line 15 one-to-one correspondence.Number It is arranged according to line 16 and 15 same layer of touch-control line, and parallel to each other.

For example, during the preparation process, touch-control line 15 and data line 16 can pass through same metallic film and utilize same structure Figure technique is formed, and thus data line 16 and touch-control line 15 are formed from the same material, so as to reduce processing step, save life Produce cost.For the conventional touch display panel of non-common data line, according to the touch-control display surface of the embodiment of the present disclosure Plate, due to each sub-pixel group multiple sub-pixels share a data line, so as to reduce data line quantity (for example, Can reduce to the half of original quantity or less), the position for the data line thus vacated on touch panel can be used for preparing touching Line is controlled, realizes touch function without increasing manufacturing process, while the wire structures of touch-control display panel can be optimized.It needs It is noted that the position for the data line vacated is exactly the position of virtual data line.

For example, in one example, each sub-pixel group 10 includes the two sub-pixels positioned at two son column of a line, such as Figure 1A Shown, which is respectively the first sub-pixel 101 and the second sub-pixel 102.It should be noted that each sub-pixel group 10 may include multiple sub-pixels (for example, three, four etc.), the embodiment of the present disclosure to this with no restriction.Below the disclosure Description in, by each sub-pixel group 10 include two sub-pixels for be described in detail.

For example, the first sub-pixel 101 can be red sub-pixel, blue subpixels or green sub-pixels, or white Sub-pixels.Second sub-pixel 102 can be red sub-pixel, blue subpixels or green sub-pixels, or white Pixel.The embodiment of the present disclosure to the color of each sub-pixel in sub-pixel group 10 with no restriction.

For example, as shown in Figure 1A, multiple sub-pixel groups 10 can arrange as multiple lines and multiple rows.Multiple data lines 16 are along sub-pixel The column direction of group 10 extends, and the column direction of sub-pixel group 10 is the Y-direction in figure.Touch-control line 15 is also along multiple sub-pixel groups 10 Column direction extend.Data line 16 and touch-control line 15 are parallel to each other and be alternately arranged.Since touch accuracy is generally below sub-pixel Precision, therefore, a touch control electrode 20 can correspond to multiple sub-pixels or multiple sub-pixel groups, thus adjacent two touch-control lines 15 Between can have at least one data line 16.For example, as shown in Figure 1A, there are two datas between adjacent two touch-control lines 15 Line 16.But not limited to this, when touch accuracy is roughly the same with subpixel accuracy, for example, a touch control electrode and a sub- picture Element or a sub-pixel group can also be not provided with data line 16 between two touch-control lines 15 adjacent when corresponding to.

For example, as shown in Figure 1A, touch-control line 15 can be set between two neighboring sub-pixel group 10 in the same row.But no It is limited to this, touch-control line 15 also can be set between two sub-pixels adjacent with a line in sub-pixel group 10.As shown in Fig. 2, In one example, when sub-pixel group 10 includes the first sub-pixel 101, the second sub-pixel 102 and third sub-pixel 103, if Data line 16 is arranged between the first sub-pixel 101 and the second sub-pixel 102, then touch-control line 15 can be set in the second sub-pixel Between 102 and third sub-pixel 103.

For example, a data line 16 can be shared by being located at multiple sub-pixel groups 10 of same row.

For example, each touch control electrode 20 is Chong Die at least one sub-pixel group 10 on the direction perpendicular to substrate 38. " overlapping " may include completely overlapped or partly overlap.For example, " partly overlapping " can indicate, in the direction perpendicular to substrate 38 On, each touch control electrode 20 is Chong Die with the organic illuminating element of multiple sub-pixels at least one sub-pixel group 10.Namely It says, each touch control electrode 20 can be located at positive throwing of at least one sub-pixel group 10 on substrate 38 in the orthographic projection on substrate 38 Within shadow.But not limited to this, " partly overlapping " can also indicate, orthographic projection position of at least one sub-pixel group 10 on substrate 38 In each touch control electrode 20 within the orthographic projection on substrate 38.In example shown in figure 1A, each touch control electrode 20 and four A sub-pixel group 10 is overlapped.But not limited to this, each touch control electrode 20 can also be Chong Die with three or five sub-pixel groups 10.This Open embodiment to this with no restriction.

For example, as shown in figure 3, multiple touch control electrodes 20 can be with array arrangement on substrate 38, these 20 structures of touch control electrode At self-capacitance electrode array, so as to be used for touch control detection.

For example, multiple touch control electrodes 20 can have identical shape, to guarantee the electrical spy of multiple touch control electrodes 20 Property it is almost the same, and then guarantee touch control detection accuracy and display picture uniformity.But not limited to this, multiple touch control electrodes 20 also can have different shapes.

S20: touch-control stage is operated, applies touch drive signal to touch control electrode via touch-control line, and read by touch-control line Take the touch-control sensing signal of touch control electrode.

There is no sequencings for aforesaid operations, also do not require that and require in each display stage with a touch-control rank Section can show that a touch-control stage is arranged in the stage in the case where meeting touch-control time precision for every two or more, by This reduces power consumption.

For example, each sub-pixel may include organic illuminating element and sub-pixel circuits.Organic illuminating element can be to have Machine light emitting diode.The sub-pixel circuits of each sub-pixel include light emission drive circuit, shine selection circuit, storage circuit, benefit Repay circuit, emission control circuit and reset circuit.It should be noted that can be with reference to touching about illustrating for sub-pixel circuits The associated description in the embodiment of display panel and the embodiment of pixel circuit is controlled, details are not described herein.

For example, driving the timing diagram of multiple sub-pixel circuits can be set according to actual needs, the reality of the disclosure It applies example and this is not especially limited.

For example, being illustrated by taking pixel circuit shown in Fig. 8 as an example.Figure 11 A to Figure 15 B is pixel circuit shown in Fig. 8 Driving method operating process.For example, as shown in Figure 11 B, it is long that the time span in touch-control stage is less than the time in display stage Degree, but the embodiment of the present disclosure is without being limited thereto.For example, according to practical application request, the time span in touch-control stage and display stage Time span can be equal；The time span in touch-control stage can also be equal to the display stage time span half or Person 1/10th.

It should be noted that square () is arranged at the position of transistor in Figure 11 A, 12A, 13A, 14A and 15A Indicate that the transistor is in the open state, circle (zero) is arranged at the position of transistor then indicates that the transistor is in cut-off shape State.Chain-dotted line with the arrow indicates signal flow.

For example, in one example, the display stage may further include reseting stage, compensated stage and luminous rank Section.For example, providing reseting controling signal to the reset circuit of multiple sub-pixels in reseting stage to shine to multiple sub-pixels Driving circuit is resetted；In compensated stage, timesharing provides scanning signal respectively to more to the compensation circuit of multiple sub-pixels The light emission drive circuit of a sub-pixel compensates；In light emitting phase, provides and shine to the emission control circuit of multiple sub-pixels Signal is controlled to drive multiple sub-pixel for emitting light.

For example, be low level in reseting stage RT, reseting controling signal RST as seen in figs. 11a and 11b, and the control that shines Signal EM, the first scanning signal S1 and the second scanning signal S2 processed are high level, thus the first reset transistor T5 and second Reset transistor T6 conducting, remaining transistor are completely in off state.At this point, the first reset transistor T5 is by third node The voltage of N53 resets to the first resetting voltage V_RET1；The voltage of 6th node N63 is reset to second by the second reset transistor T6 Resetting voltage V_RET2.First resetting voltage V_RET1With the second resetting voltage V_RET2Such as be low-voltage, for example, low-voltage can be with For 0V.

For example, compensated stage includes first stage CT1 and second stage CT2 as shown in Figure 12 A to Figure 13 B.In the first rank Section CT1 provides the first scanning signal S1 to the first light emission drive circuit to the first compensation circuit 505 of the first sub-pixel 101 501 compensate；In second stage CT2, the second scanning signal S2 is provided to the second compensation circuit 605 of the second sub-pixel 102 To be compensated to the second light emission drive circuit 601.

For example, as illustrated in figs. 12 a and 12b, CT1 in the first stage, reseting controling signal RST become high level, first Scanning signal S1 becomes low level, and LED control signal EM and the second scanning signal S2 keep high level.At this point, the first driving Transistor T1, first choice transistor T7 and the first compensation transistor T3 conducting, remaining transistor are in off state.As a result, First data-signal V_data1Via the first driving transistor T1, the compensation of first choice transistor T7 and first transistor T3 to third Node N53 charges, and the voltage for charging to third node N53 always is V_data1-V_th1Until, V_th1For the first driving transistor The threshold voltage of T1, the voltage is (that is, V_data1-V_th1) can store in the first storage capacitance C1.At this point, the first driving crystal The voltage of the grid of pipe T1 is V_data1-V_th。

For example, as shown in figures 13 a and 13b, in second stage CT2, reseting controling signal RST and LED control signal EM High level is kept, the first scanning signal S1 becomes high level, and the second scanning signal S2 becomes low level.At this point, the second driving Transistor T2, the second selection transistor T8 and the second compensation transistor T4 conducting, remaining transistor are in off state.As a result, Second data-signal V_data2Via the second driving transistor T2, the compensation of the second selection transistor T8 and second transistor T4 to the 6th Node N63 charges, and the voltage for charging to the 6th node N63 always is V_data2-V_th2Until, V_th2For the second driving transistor The threshold voltage of T2, the voltage is (that is, V_data2-V_th2) can store in the second storage capacitance C2.At this point, the second driving crystal The voltage of the grid of pipe T2 is V_data2-V_th2。

It should be noted that there is no sequencings by first stage CT1 and second stage CT2.First stage can be It executes, can also be executed after second stage CT2 before two-stage CT2.

For example, as shown in figs. 14 a and 14b, becoming low level in light emitting phase LT, LED control signal EM, first sweeps It retouches signal S1 and reseting controling signal RST and keeps high level, the second scanning signal S2 becomes high level.At this point, the first driving Transistor T1, the second driving transistor T2, the first control transistor T9, the second control transistor T11, third control transistor The control of T10 and the 4th transistor T12 is in the conductive state, and remaining transistor is in off state.Based on the first driving crystal The saturation current formula of pipe T1, available the first glow current signal I for flowing through the first driving transistor T1_OLED1It can indicate Are as follows:

I_OLED1=K (V_GS1–V_th1)²

=K [V_dd–(V_data1–V_th1)–V_th1]²

=K (V_dd–V_data1)²

V in above-mentioned formula_GS1For the voltage difference between the grid and source electrode of the first driving transistor T1, V_ddFor the first power supply Hold the first electrode voltage signal of V1 output, V_th1It is the threshold voltage of the first driving transistor T1.By can see in above formula, First glow current signal I_OLED1Not by the threshold voltage V of the first driving transistor T1_th1Influence, and only with first electricity The first electrode voltage signal V of source V1 output_ddWith the first data-signal V_data1It is related.And the first data-signal V_data1By counting It is directly transmitted according to signal end Vd, the threshold voltage V with the first driving transistor T1_th1It is unrelated, it thus can solve the first drive Dynamic transistor T1 operates the problem of causing threshold voltage shift due to manufacturing process and for a long time, it is ensured that the first luminous electricity Flow signal I_OLED1Accuracy, eliminate first driving transistor T1 threshold voltage to I_OLED1Influence, guarantee first organic hair Optical diode OLED1 is worked normally.

For example, first electrode voltage signal V_ddIt can be high level signal.

Similarly, the second glow current signal I of the second driving transistor T2 is flowed through_OLED2It can indicate are as follows:

I_OLED2=K (V_GS2–V_th2)²

=K [V_dd–(V_data2–V_th2)–V_th2]²

=K (V_dd–V_data2)²

V in above-mentioned formula_GS2For the voltage difference between the grid and source electrode of the second driving transistor T2, V_th2It is the second driving The threshold voltage of transistor T2.Second glow current signal I_OLED2Not by the threshold voltage V of the second driving transistor T2_th2Shadow It rings, and the only first electrode voltage signal V with the first power end V1 output_ddWith the second data-signal V_data2It is related.
