Problems solved by technology

Due to the large number of touch sensing electrodes on the display panel, the large number of touch sensing signal lines, and the small number of interfaces of the driver IC, the touch IC is usually used to process the data of the touch sensing signal lines and then passed through Fewer interfaces are transmitted to the driver IC for calculation, and the design of the touch IC increases the cost of the touch display panel, and the touch IC needs to be bound to the flexible circuit board, which is prone to problems such as poor binding

Abstract

The invention discloses a touch display panel, a driving method thereof and a touch display device. The touch display panel comprises an array substrate and a color film substrate arranged opposite to the array substrate, wherein the color film substrate comprises n touch sensing electrodes and n touch sensing signal lines electrically connected with the touch sensing electrodes in one-to-one correspondence; the array substrate comprises a driver chip and a signal converting unit, and the signal converting unit comprises n input ends and m output ends; the touch sensing signal lines are electrically connected with the input ends in one-to-one correspondence, and the m output ends are electrically connected with the driver chip; the signal converting unit is used for converting signals input at the n input ends into m signals and then transmitting the m converted signals to the m output ends respectively, wherein m and n are positive integers respectively, and m is smaller than n. According to the touch display panel and the touch display device, the quantity of interfaces of the driver chip for a touch function can be reduced, the application of a touch chip can be omitted, and the cost of the touch display pane and the risk of low touch precision caused by poor binding for the touch chip are reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of touch display technology, in particular to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] Touch screens are divided into self-capacitive touch screens and mutual-capacity touch screens according to their touch control principles. Existing mutual capacitive touch screens usually use touch reference electrodes and touch sensing electrodes to form mutual capacitance, and detect touch points by measuring the change of charge in the mutual capacitance during touch. [0003] In the driving architecture of the above-mentioned mutual capacitance touch display screen, each touch sensing electrode is connected to at least one touch sensing signal line, and the touch sensing signal line is used to return the signal sensed by the touch sensing electrode to the driver IC for calculation. . Due to the large n...
