Scan line SL1~SLn, data line DL1~DLm.Wherein, each intersection of scan line SL1~SLn and data line DL1~DLm
It is respectively coupled to pixel PIX_1_1~PIX_m_n.The operation principles of panel 100 should be known to those skilled in the art,
This will not be repeated here.Drive module 102 includes a control unit CON, one first driving circuit DRI_S and one second driving circuit
DRI_G.Control unit CON is used for generating an a first control signal CON_S and second control signal CON_G.First driving electricity
Road DRI_S is used for, according to first control signal CON_S, data drive signal S1~Sm being generated, with driving data line DL_1~DL_
m.Second driving circuit DRI_G is used for, according to second control signal CON_G, generating gate drive signal G1~Gn, is swept with driving
Retouch line SL1~SLn.Due to each pixel on each panel load may because of panel-shaped or processing procedure difference incomplete phase
Together, therefore, the load per scan line SL1~SLn and each data line DL_1~DL_m is also not exactly the same.For example,
When a panel is a round, ellipse or is irregular, for the first driving circuit DRI_S, it is located at first row
(column) load of pixel PIX_1_1~PIX_1_m and the load of pixel PIX_2_1~PIX_2_m positioned at the 2nd row can

It is also different to load DLD_1~DLD_m.For example, when the load on pixel PIX_1_1~PIX_1_n it is relatively low (such as close to circle
The fringe region of shape panel), then data linear load DLD_1 is relatively low, and control unit CON adjusts first control signal CON_ accordingly
S1, to make driving unit DRI_S1 generate the lower data drive signal S1 of driving capability；Alternatively, when pixel PIX_2_1~
Load on PIX_2_n is higher (such as middle section close to round panel), then data linear load DLD_2 higher, and control is single
First CON adjusts first control signal CON_S2 accordingly, to generate the higher data drive signal S2 of driving capability, with such
It pushes away.Therefore, control unit CON can control each driving unit DRI_S1~DRI_Sm and generate corresponding data drive signal S1
~Sm, individually to adjust the driving capability of each driving unit DRI_S1~DRI_Sm.It is worth noting that, control unit

In addition to this, other than the numerical value of practical metric data linear load DLD_1~DLD_m, control unit CON also can be another
According to a stabilitys of the data linear load DLD_1~DLD_m after receiving data drive signal S1~Sm or a time-to-climb, sentence
Disconnected data linear load DLD_1~DLD_m simultaneously assesses drives of the data drive signal S1~Sm to data linear load DLD_1~DLD_m
Whether kinetic force is suitable, to determine first control signal CON_S1~CON_Sm, to generate suitable data drive signal S1
~Sm.
