In the following, will be equal with the first transistor T1, second transistor T2, third transistor T3 and driving transistor 240,340 For NMOS transistor, the working principle of Fig. 2 and embodiment illustrated in fig. 3 is described in conjunction with timing diagram as shown in Figure 4.

P1 in the first stage applies high level signal, Xiang Fa to the first scan signal line S1 and the second scan signal line S2 Optical control signal line E1 applies low level signal, and applies initializing signal Vinit, the first transistor T1 and the to data line D1 Two-transistor T2 conducting, so that the grid potential Vg and source potential Vs of driving transistor 240,340 reach Vinit.

Then, in second stage P2, apply high level signal to the second scan signal line S2 and LED control signal line E1, Apply low level signal to the first scan signal line S1, and apply reference signal Vref to data line D1, so that second is brilliant Body pipe T2, third transistor T3 and driving transistor 240,340 are connected, and the grid potential Vg of driving transistor 240,340 reaches Vref, and the source potential Vs of transistor 240,340 is driven to reach Vref- | Vth |.Herein, Vth be driving transistor 240, 340 threshold voltage.

It is shown in Figure 10, it is the schematic diagram of one embodiment of the organic light emitting display panel of the application.

Organic light emitting display panel shown in Fig. 10 includes multirow pixel unit 1010, and every row pixel unit 1010 includes more The organic light emissive pixels driving circuit of a each embodiment of the application.For example, each of every row pixel unit 1010 pixel list Member includes an organic light emissive pixels driving circuit.

Every row pixel unit connects first scan signal line and second scan signal line.For example, being answered some With in scene, signal S1~Sm of the first scan signal line and signal S1 '~Sm ' of the second scan signal line can be respectively by two A shift register 1020,1030 generates.In these application scenarios, signal S1~Sm of the first scan signal line can have Have a waveform identical with the S1 in Fig. 4, and signal S1 '~Sm ' of the second scan signal line can have it is identical as the S2 in Fig. 4 Waveform.

The organic light emitting display panel of the present embodiment, due to using organic light emissive pixels driving circuit as described above, So that pixel circuit shared chip area in display panel is smaller, be conducive to the realization of high PPI display panel.Further, since Organic light emissive pixels driving circuit as described above may be implemented to improve the present embodiment to the threshold compensation of driving transistor The brightness homogeneity of organic light emitting display panel.

It is shown in Figure 11, it is the schematic diagram of the organic light emitting display panel of another embodiment of the application.

Similar with organic light emitting display panel shown in Fig. 10, the organic light emitting display panel of the present embodiment equally includes more Row pixel unit 1110, every row pixel unit 1110 include the organic light emissive pixels driving circuit of each embodiment of multiple the application. For example, each of every row pixel unit 1110 pixel unit includes an organic light emissive pixels driving circuit.In addition, every Row pixel unit is all connected with first scan signal line and second scan signal line.

Unlike embodiment illustrated in fig. 10, in the present embodiment, the second scanning letter being connect with the i-th row pixel unit Number line is multiplexed with the first scan signal line of i+1 row pixel unit, and i is positive integer.

Specifically, as shown in figure 11, the second scan signal line S2 of the first row pixel is multiplexed with the of the second row pixel Scan signal line.So, the first scanning signal and the second scanning signal needed for each organic light emissive pixels driving circuit It can be generated by the same shift register 1120, to further reduce version shared by circuit in organic light emitting display panel The area of pictural surface.

Each organic light emissive pixels driving circuit in the organic light emitting display panel of the present embodiment for example can be using such as Fig. 8 Shown in timing driven.

It will illustrate the multiplexing relationship of each scan signal line in adjacent rows pixel unit with the timing of Figure 12 below.

It as shown in figure 12, is the exemplary timing diagram of scan signal line in Figure 11.In figure 12 it can be seen that scanning signal The driving signal applied on the driving signal relative scanning signal wire S1 applied on line S2 postpones a row period, therefore, scanning The driving signal applied in the driving signal and scan signal line S2 applied on signal wire S1 can be by the shift LD in Figure 11 Adjacent two shifting deposit units output in device 1120.Similarly, scan signal line Si+1The driving signal relative scanning of upper application is believed Number line SiThe driving signal of upper application postpones a row period, therefore, scan signal line Si1The driving signal and scanning of upper application The driving signal applied on signal wire Si2 can be defeated by adjacent two shifting deposit unit in the shift register 1120 in Figure 11 Out.Herein, i1 and i2 is two adjacent natural numbers, and meeting 0 < i≤m, m is the pixel unit of organic light emitting display panel Line number.In addition, when driving the period (namely the first row period shown in Figure 12) of the first row pixel, scan signal line S2 is used as the second scan signal line in the first row pixel in each organic light emissive pixels driving circuit.And driving the second row pixel Period (namely second row period shown in Figure 12) when, scan signal line S2 be used as the second row pixel in each organic light emission The first scan signal line in pixel-driving circuit.Similarly, in the period for driving the i-th row pixel (namely shown in Figure 12 I-th row period) when, scan signal line Si+1As the second scanning in each organic light emissive pixels driving circuit in the i-th row pixel Signal wire.And when driving the period (namely i+1 row period shown in Figure 12) of i+1 row pixel, scan signal line Si+1As the first scan signal line in each organic light emissive pixels driving circuit in i+1 row pixel.

In addition, the control signal applied from the LED control signal line E2 that can also be seen that the second row of driving in Figure 12 It can be obtained by the one row period of control signal delay applied on the LED control signal line E1 of driving the first row.Similarly, It is inferred that the control signal applied on the LED control signal line Ei of the i-th row of driving can be by the luminous control of the (i-1)-th row of driving One row period of the control signal delay applied on signal wire processed obtains.

The timing shown in Figure 12 it is found that each organic light emissive pixels driving circuit for driving i+1 row pixel the Scan signal line reusable does the second scanning signal for driving each organic light emissive pixels driving circuit of the i-th row pixel Line, and the initial time of the light emitting phase of the i-th row pixel is identical as the initial time in P1 stage of i+1 row pixel.Herein, I is natural number, and 0 < i≤m.

It is inferred that the signal applied when driving the m row pixel unit of the present embodiment, on scan signal line Sm+1 It can be obtained by the one row period of signal delay applied on scan signal line Sm.

Organic light emitting display panel shown in comparison diagram 10 and Figure 11 is it is known that if organic hair shown in Figure 10 and Figure 11 Light display panel includes m row pixel unit, and organic light emitting display panel shown in Fig. 10 needs 2m scan signal line to drive Move each row pixel unit, and organic light emitting display panel shown in Figure 11, due to for driving the organic light emission of adjacent rows pixel A wherein scan signal line can be shared between pixel-driving circuit, thus only needs m+1 scan signal line that can drive Each row pixel unit is moved, to further reduce chip area shared by circuit in organic light emitting display panel.
