Embodiment Construction

[0040] An embodiment of the present invention provides a touch panel, including a base substrate, a plurality of touch electrodes and a plurality of active pen electrodes disposed on the base substrate, wherein the size of the active pen electrodes is smaller than that of the touch The size of the control electrode.

[0041] In the embodiment of the present invention, in the touch panel, the active pen electrode is separately set as the receiving electrode of the active pen, instead of using the existing touch electrode as the receiving electrode of the active pen, because the size of the active pen electrode is smaller than the touch electrode Therefore, compared with the touch electrodes, the RC loading of the active pen electrode is very small, thus, the attenuation of the active pen signal can be reduced, and the active pen touch is more sensitive and the effect is better.

[0042] If the touch panel is an in-cell touch panel, when the touch electrodes of the in-cell (In C...

Abstract

The invention provides a touch panel and a manufacturing method therefor as well as a touch apparatus. The touch panel comprises a substrate, as well as a plurality of touch electrodes and a plurality of active pen electrodes, that are arranged on the substrate, wherein the size of each active pen electrode is smaller than that of each touch electrode; the touch electrode is used for determining a touch position of a finger; and the active pen electrode is used for determining a touch position of an active pen. According to the touch panel, the manufacturing method for the touch panel, and the touch apparatus, the active pen electrodes are separately arranged as receiving electrodes of the active pen; the size of each active pen electrode is smaller than that of each touch electrode, so that RC loading of the active pen electrodes is very small relative to the touch electrodes; and therefore, signal attenuation of the active pen can be reduced and the touch of the active pen is more sensitive.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch panel, a manufacturing method thereof, and a touch device. Background technique [0002] Styluses for touch screens mainly include passive pens and active pens. Please refer to figure 1 , figure 1 It is a schematic diagram of the working principle of the existing active pen. The active pen 11 has a corresponding signal generator that can send out a pulse signal of a specific frequency. This pulse signal is used as the generating electrode (TX) of the active pen 11. When the active pen 11 approaches In a conventional touch screen, the touch electrodes 12 on the touch screen are used as receiving electrodes (RX) to receive signals from the active pen 11 , so as to detect the corresponding position of the active pen 11 . At the same time, if the distance between the active pen 11 and the touch screen is adjusted, the signal received by the receiving electrode (RX) w...
