Touch display drive circuit, drive method and touch display panel

A drive method of a touch display drive circuit, comprising:

• writing, in each sub-frame within a single refresh duration of a display panel, a display signal to a corresponding partition through an i-th multiplex selection module group and a touch signal to the corresponding partition through a j-th multiplex selection module group;
• wherein the i-th multiplex selection module group corresponding to each sub-frame is different, and the j-th multiplex selection module group corresponding to each sub-frame is different, and the i and j are integers less than k and greater than 1;
• and
• wherein said writing, in each sub-frame within the single refresh duration of the display panel, the display signal to the corresponding partition through the i-th multiplex selection module group and the touch signal to the corresponding partition through the j-th multiplex selection module group comprises:
• writing, for a g-th sub-frame, the display signal to a g-th corresponding partition through a g-th multiplex selection module group and the touch signal to a q-th corresponding partition through a q-th multiplex selection module group;
• wherein a sum of g and q is equal to that of K+1.

A touch display panel, comprising:

• M rows and N columns of touch display units and a touch display drive circuit, applied to a display panel, wherein the display panel comprises M rows and N columns of touch display units;
• the M rows and N columns of touch display units form K partitions along a column direction, each partition corresponds to a multiplex selection module group, and each partition comprises m rows and N columns of touch display units;
• the touch display drive circuit comprises a control module and M×N multiplex selection modules, the control module is respectively connected to each of the multiplex selection modules, and the M×N multiplex selection modules are correspondingly connected to the M rows and N columns of touch display units in an one-to-one manner, respectively;
• and
• the control module controls a multiplex selection module connected with a first touch display unit to write a display signal to the first touch display unit, and simultaneously controls a multiplex selection module connected with a second touch display unit to write a touch signal to the second touch display unit, the first touch display unit and the second touch display unit are respectively located in a same row and a same column in any two different partitions;
• wherein a single refresh duration of the display panel comprises K sub-frames, and in a g-th sub-frame, a g-th multiplex selection module group is configured to write the display signal to a g-th corresponding partition, and a q-th multiplex selection module group is configured to write the touch signal to a q-th corresponding partition;
• wherein a sum of g and q is equal to that of K+1;
• wherein m, M, N, and K are integers greater than 1;
• and
• wherein the M rows and N columns of touch display units form K partitions along a column direction, and each partition comprises m rows and N columns of touch display units.
