1. An electrophoresis display with a gapped micro-partition structure, comprising:
a control substrate, comprising a first face and a second face;
a driving circuit layer, arranged on the second face of the control substrate and comprising a plurality of thin film transistors, a plurality of gate lines, and a plurality of data lines, at least one of the gate lines electrically connected to gates of the thin film transistors, at least one of the data lines electrically connected to drains or sources of the thin film transistors;
a control electrode layer, arranged on a surface of the driving circuit layer away from the control substrate and comprising a plurality of control electrodes, at least one of the control electrodes electrically connected to the source or the drain of one of the thin film transistors;
a micro-partition structure comprising a plurality of partition walls to define a plurality of chambers configured to fill with an electrophoresis material, a colloidal solution comprising at least one kind of charged color particles, wherein, at least two of the partition walls have a crevice between each other, an area of the crevice is not more than 50% of an area of the partition wall, or a length of the crevice is not more than 50% of a length of the partition wall; and
an opposite substrate, disposed on a side of the micro-partition structure away from the control substrate;
wherein the micro-partition structure is disposed between the control substrate and the opposite substrate.
