Touch control display device and driving method thereof

A touch control display device comprising a first substrate;

• wherein the first substrate comprises a plurality of common electrodes and a touch control driving electrode block matrix arranged in a same layer;
• a projection area of one matrix row of the touch control driving electrode block matrix on the first substrate corresponds to at least one gate line;
• each column of the touch control driving electrode block matrix comprises a first touch control driving electrode block and a second touch control driving electrode block;
• the second touch control driving electrode blocks in different matrix columns belong to different matrix rows;
• the first substrate further comprises:
• a plurality of first touch control driving signal transmission lines corresponding to each column of the touch control driving electrode block matrix;
• the first touch control driving signal transmission lines being electrically connected with first touch control driving electrode blocks in corresponding matrix columns, and configured to transmit in turns a first touch control driving signal to the first touch control driving electrode blocks in the corresponding matrix columns in a display time period;
• wherein gate lines corresponding to the first touch control driving electrode blocks which receive the first touch control driving signal are in an off state;
• when a gate line corresponding to the first touch control driving electrode block in one matrix column is in the off state, a gate line corresponding to the second touch control driving electrode block in the matrix column is in an on state;
• a second touch control driving signal transmission line connected with the second touch control driving electrode blocks in all the matrix columns of the touch control driving electrode block matrix, and configured to transmit a second touch control driving signal to the second touch control driving electrode blocks in all the matrix columns between adjacent display time periods.
