Embodiment Construction
[0028] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0029] The present invention provides a solution to the problem that the sub-electrodes in the existing touch control substrate are loaded with large differences in touch driving signals.
[0030] On the one hand, the embodiments of the present invention provide a touch substrate, such as figure 1 shown, including:
[0031] A base substrate 1, a touch electrode 2 and a plurality of driving signal lines 3 formed on the base substrate 1 ( figure 1 The driving signal lines of the upper left sub-electrode and the lower right sub-electrode are used as an example for introduction).
[0032] Wherein, the touch electrode 2 is composed of a plurality of sub-electrodes 21 distributed in an array, and each sub-electrode 21 corresponds to a different driving signa...

The present invention provides a touch control substrate, a touch panel and a touch display device. The touch control substrate includes a touch control electrode and a plurality of driving signal lines formed on a substrate; the touch control electrode is composed of a plurality of sub-electrodes distributed in an array manner; each of the sub-electrodes is corresponding to different driving signal line; the touch control driving signals are loaded through corresponding driving signal lines; each driving signal line has the same area of the overlapping portions of the touch control electrodes; each driving signal line includes a valid transmission part which loads the touch control driving signal to the corresponding sub-electrode and a redundant part other than the effective transmission part; and the resistance value of the effective transmission part of all driving signal lines is within the preset resistance range. In that touch control electrode, the resistance value of the effective transmission part of each sub-electrode of the touch control electrode is controlled in a small range so as to reduce the difference of the load touch control driving signal between sub-electrodes in the touch control recognition phase.
Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a touch substrate, a touch panel and a touch display device. Background technique [0002] In an existing touch display device, the touch electrodes on the touch substrate are composed of sub-electrodes arranged in an array, and each sub-electrode is connected to the driver IC on the outside of the touch substrate through its corresponding signal line, thereby Capable of loading the touch drive signal output by the drive IC. [0003] Obviously, the distances between the sub-electrodes arranged in an array and the driving ICs are different, so that the lengths of the signal lines corresponding to the sub-electrodes are also different. The signal line also has a certain resistance. If the influence of the resistance on the signal line is considered, actually each sub-electrode is different when loaded with a touch driving signal. This difference may cause a series of probl...
