Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0031] An embodiment of the present invention provides a touch display panel. The touch display panel can be a self-capacitive touch display panel, or a mutual-capacitance touch display panel.

[0032] The structure of the touch display panel in which the touch display panel is self-capacitive is described below.

[0033] figure 1 It is a schematic cross-sectional view of the structure of an implementation manner of the touch display panel provided by the embodiment of the present invention. Such as figure 1 As shown, the ...

Abstract

The invention discloses a touch display panel and a touch display device. The touch display panel comprises a plurality of touch electrodes and a plurality of force touch electrodes, wherein the touch electrodes and the force touch electrodes are located on the same membrane layer; at least one touch electrode is provided with at least one force touch electrode, the touch electrodes and the force touch electrodes are electrically insulated; the force touch electrodes are arranged by avoiding the center point of an area defined by outer edges of the touch electrodes. The touch display panel and the touch display device can realize position touch and can realize force touch and can realize uniform distribution of electric fields in the touch electrodes, so that uniformity of the touch quantity of position touch can be realized, the signal-to-noise ratio is reduced, and the touch sensitivity of position touch is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device. Background technique [0002] Touch display devices with both display and touch functions (for example: touch mobile phones and touch tablet computers, etc.) have pervaded people's lives. With the development of technology, manufacturers of touch display devices have developed a new touch technology: force touch. Utilizing this technology, the touch display device can sense the intensity of the applied pressure, and call out corresponding different functions according to the intensity of the pressure. [0003] In the prior art, a touch display device manufactured using pressure-sensitive touch technology is generally realized by integrating pressure-sensitive touch electrodes in the existing touch display device. If an additional layer of pressure-sensitive touch electrodes is added to the touch display device, the...
