Embodiment Construction
[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0022] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract
The invention relates to a touch control induction film and a touch control display device, induction electrodes and imitation decorative patterns are arranged on the touch control induction film through an etching process, the imitation decorative patterns are arranged between the induction electrodes, and the imitation decorative patterns and the induction electrodes are arranged in an insulatedand spaced mode; the imitation decorative pattern comprises a first imitation decorative electrode and a second imitation decorative electrode which are arranged at an insulation interval, and the first imitation decorative electrode and the induction electrode are adjacent and are arranged at an insulation interval; the second imitation decoration electrode is located on the side, away from theinduction electrode, of the first imitation decoration electrode. The area of the second imitation decoration electrodes is larger than that of the first imitation decoration electrodes, and the number of the second imitation decoration electrodes is smaller than that of the first imitation decoration electrodes. According to the touch sensing film and the touch display device, even if the sensingelectrodes and the imitation decorative patterns are short-circuited, the area increase amplitude of the sensing electrodes is very small, the capacitance increase amplitude is very small, and the electrical performance of the touch sensing film is not affected. In addition, the touch sensing film can also avoid a water ripple phenomenon caused by deformation in a high-temperature environment.
Description
technical field [0001] The present invention relates to the technical field of touch devices, in particular to a touch sensitive film and a touch display device. Background technique [0002] Touch devices or touch panels are more and more widely used in electronic products. The touch devices can enable users to directly interact with displayed information without any intermediate devices such as a mouse or a physical keyboard. The touch sensing film in the touch device, for example, the ITO film is provided with sensing electrodes through an etching process, and the sensing electrodes are used to sense touch signals, and the area between the sensing electrodes is provided with a dummy pattern (dummy pattern) through an etching process. ), the imitation pattern and the induction electrode are spaced apart and then insulated. The imitation decorative pattern is composed of a plurality of small areas which are not connected to each other, and the small areas are spaced apart ...
