Fig. 3 is the pixel circuit drive method oscillogram shown in Fig. 2, as shown in figure 3, the electricity of the pixel with compensation function
Road operation principle is as follows：
The t1 periods（Initial phase）, the second scanning signal sn2, the 3rd scanning signal sn3 are low level signal, T2,
Initialization voltage ELVL is stored in N2 by T4 transistors and T1, T7 transistor turns, initialization voltage ELVL by T1, T7 and T4
On node, N2 node initializings.The t2 periods（Compensated stage）, the 4th scanning signal sn4 is low level signal, and the second scanning is believed
Number sn2 continues to keep low level signal, T2, T4, T8 transistor turns, and now transistor T3 is diode connected mode, Dm numbers
It is believed that Dm data-signals are stored in N2 nodes by number process transistor T2, a T3, now N2 node voltages are Dm-Vth, are now completed
Threshold voltage vt h compensation.The T3 periods（Glow phase）, the first scanning signal sn1 is low level signal, transistor T5, T6
Conducting, OLED start to light.The electric current for flowing through OLED is related as driving tube T3 gate source voltage, it is known that then flows through OLED's
Electric current is unrelated with threshold voltage vt h, it is achieved thereby that threshold voltage compensation effect.
It is internal in OLED to be arranged in order with one-row pixels according to RGBRGB order.When with compensation function
Image element circuit and data distributor cooperating when, the data-signal of same row pixel is provided by same data lines.Fig. 4 is

Data distributor is data selector, it is therefore an objective to reduces peripheral data line.After data distributor, on a data wire
Data-signal is divided into the data-signal of three data lines, therefore the total amount of data wire can reduce 1/3.As shown in figure 5, data point
Three of orchestration switches often open once an i.e. data-signal of transmission, after three switching tubes of data distributor are opened successively,
Data-signal data respectively becomes DR, tri- data-signals of DG, DB, is respectively transmitted in corresponding image element circuit.
Because data distributor parasitic capacitance is very big, in the t1 periods, data-signal Dm is high level, will be stored in number
According in the parasitic capacitance of line, the parasitic capacitance can be charged to driving transistor T3 grid, the voltage after T3 gate charges
For Dm-Vth.In the t2 periods, Dm is changed into the grid that low level will be admitted to T3, but now T3 grid voltages are Dm-Vth, greatly
In low level Dm.Therefore T3 grids can not be written into, and cause the pixel not light.
