A touch display panel and a touch display device

Abstract

The invention discloses a touch display panel and a touch display device, which are used to avoid poor contact in the bonding area, when the signal lead-out lines and the touch sensor lead-out lines are bound to integrated circuit components, and improve the product yield . Specifically, when the integrated circuit element is electrically connected to the signal lead-out line and the touch sensor lead-out line through conductive glue, the conductive glue contains conductive particles, and the conductive particles can only conduct electricity when they are compressed to 80% of their diameter. Compared with the prior art, in the embodiment of the present invention, in the binding area, the difference between the distance between the lead-out lines of the touch sensor and the upper surface of the substrate and the distance between the lead-out lines of the signal and the upper surface of the substrate is less than 80% of the diameter of the conductive particles. Therefore, it avoids the phenomenon of poor contact when the integrated circuit element is electrically connected with the signal lead-out line and the touch sensor lead-out line through the conductive glue, and the product yield rate is improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display panel and a touch display device. Background technique [0002] Currently, organic light emitting diode (Organic Light Emitting Diode, OLED) display screens with integrated touch functions have become a hot spot for high-end smart products. [0003] In the prior art, a device with a touch control function is arranged in an OLED display device to form a touch display panel with both touch control and display functions. Among them, according to the degree of integration between the touch element and the display panel, it can be divided into two types. The type in which touch elements are made on the outer surface of the display panel is called On-cell touch display panel, which has a low degree of integration and a large thickness; the type in which the touch elements are directly made inside the display panel is called On-cell touch display panel. It is an...

However, the insulating layer 16 increases the height difference between the side of the touch electrode lead-out lines 14 away from the array substrate and the side of the display signal lead-out lines away from the array substrate.

[0005] Therefore, see figure 1 Because the height difference between the lead-out lines of the touch signal and the lead-out lines of the display signal used for display is too large, the integrated circuit chip 13 may experience poor contact during bonding, thereby affecting the effect of display or touch control.
