Problems solved by technology

For example, the greater the thickness of the alignment material layer remaining on the touch conductor and the touch pad, the greater the minimum external force (active force) that can sense touch, that is, the greater the sensing capability of the touch panel. Difference

Abstract

The invention discloses a touch display panel which comprises first substrate and a second substrate. The first substrate comprises a plurality of induction units, each induction unit is provided with a main induction pattern and at least one primary induction pattern, wherein the at least one primary induction pattern is electrically connected with the main induction pattern, and the size of theat least one primary induction pattern is smaller than that of the main induction patter. The second substrate comprises a plurality of induction electrodes, and each induction electrode is arranged corresponding to one induction unit on the first substrate.

Description

technical field [0001] The present invention relates to a sensing structure, and in particular to a resistive sensing structure and a touch display panel with the resistive sensing structure. Background technique [0002] In general touch display panel design, it can be roughly classified into capacitive, resistive, photosensitive, etc. based on the design principle of the touch sensing mode; ) and built-in (integrated type) two. Among them, the built-in resistive touch panel forms a plurality of touch conductors on the opposite substrate and a photo spacer, and forms a plurality of touch pads on the active device array substrate. When the user presses the opposite When connecting the substrate, the touch conductor on the spacer can be connected to the touch pad on the active device array substrate, so as to locate the position pressed by the user. Therefore, the gap between the touch conductor and the touch pad will affect the sensing capability of the touch panel. [00...
