Problems solved by technology
[0003] However, in the sub-electrode array, the distance between the sub-electrodes at different positions and the driver IC is different, resulting in different lengths of the signal lines corresponding to the sub-electrodes at different positions, and different resistance values of the signal lines with different lengths. The difference leads to different response speeds of different sub-electrodes to the touch driving signal, thereby reducing the quality of the touch display device and poor user experience

The invention discloses a touch substrate, a touch panel and touch display equipment, the touch substrate comprises a substrate body, a plurality of signal lines and sub-electrode arrays arranged on the substrate body, and sub-electrodes included in the sub-electrode arrays are in one-to-one correspondence with the signal lines; the sub-electrode array comprises a plurality of electrode areas, andeach electrode area corresponds to different parallel numbers; the signal lines corresponding to the sub-electrodes comprise one or more signal branch lines connected in parallel, and the number of the signal branch lines connected in parallel is the number of the signal branch lines connected in parallel corresponding to the electrode areas where the sub-electrodes are located; the difference between the line resistance values of the signal lines corresponding to any two sub-electrodes in the sub-electrode array is smaller than a preset threshold value. By connecting the signal branch linesin the signal lines of the sub-electrodes in parallel, the circuit resistance corresponding to the sub-electrodes is reduced, the resistance difference of sub-electrode signal line routing in the touch substrate is improved, the difference of reaction speeds of different sub-electrodes to touch driving signals is reduced, and a better touch operation recognition effect can be achieved.
Description
technical field [0001] The present application relates to the field of touch technology, in particular to a touch substrate, a touch panel and a touch display device. Background technique [0002] At present, in touch display devices, the touch electrodes on the touch substrate are composed of sub-electrodes arranged in an array, and each sub-electrode is connected to the drive IC (Integrated Circuit Chip, chip) outside the touch substrate through its corresponding signal line. , so that the touch driving signal output by the driving IC can be loaded. [0003] However, in the sub-electrode array, the distance between the sub-electrodes at different positions and the driver IC is different, resulting in different lengths of the signal lines corresponding to the sub-electrodes at different positions, and different resistance values of the signal lines with different lengths. The difference leads to different response speeds of different sub-electrodes to the touch driving s...
