Description
Technical Field

Background
At present, the touch control and display functions of the smart phone are controlled independently by two chips, and the largest TDDI (Touch and Display Driver Integration, touch control and display driver integration) is characterized by integrating the touch control chip and the display chip into a single chip. TDDI possesses touch performance good, and the appearance is thinner, and the transmissivity is higher, advantage such as cost down. The TDDI is shared with the display in touch control and time-sharing driving mode is adopted in driving, the common electrode COM electrode provides COM signals in a driving module (Integrated Circuit ) in display, and the driving module provides touch control signals in touch control.
The touch signal of the TDDI is provided by the driving module, so that the output end number of the driving module is more. As TDDI is increasingly being applied to larger displays such as vehicles and computers, the number of driving modules and output terminals of the driving modules needs to be increased, resulting in excessive cost.
When the TDDI display screen performs touch control, the signal of the transmitting Tx block is hopped to the touch control signal from the COM signal instantly, so that the coupling capacitance is larger, and therefore, when the Tx block is hopped, synchronous hopping is required for peripheral signal lines, such as GOA (Gate Driver on Array, array substrate row driving technology) signals, ET signals (ET signals comprise DR-Red resistance detection signals, DG-Green resistance detection signals, DB-Blue resistance detection signals, SW-detection switch opening signals), common electrode Vcom signals and the like, so that the coupling capacitance is reduced.
However, since the peripheral signal lines are provided with signals by the driving module, the number of the output ends of the driving module is increased due to different output ends, and the problem that the touch signals of the Tx blocks are asynchronous with the jump of the peripheral signal lines due to different resistances and capacitances is also caused among the signal lines, so that touch errors are easily caused, and abnormal display is caused.
