Description

touch device

The present invention relates to an electronic device, and more particularly, to a touch device.

In touch devices, grounding lines are usually set at the junctions or edges of different signal lines to reduce mutual interference between signals and/or reduce external influences (eg, environment, or other electronic components). However, when the touch device is powered on, there may be a corresponding potential difference between the ground line and the signal line, and under high temperature or high humidity, the signal line is prone to moisture (such as water in the environment) moisture, corrosion, oxidation, and/or reduced conductivity due to air or human sweat when using the touch device). Therefore, the yield, quality or service life of the touch device may be affected.

In recent years, coupled with the design trend of narrow bezels, the above effects may be more serious.

The present invention provides a touch device, which can have better yield, quality or service life.

The touch device of the present invention includes a substrate, a first signal line, a second signal line, a third signal line and a fourth signal line, wherein the substrate has a sensing area and a non-sensing area. The first signal line and the second signal line are located in the non-sensing area and extend to the sensing area. The third signal line is located in the non-sensing area and adjacent to the first signal line, and the third signal line has at least a first mesh line area. The fourth signal line is located in the non-sensing area and adjacent to the second signal line, and the fourth signal line has at least a second mesh line area.

Based on the above, the present invention can reduce the damage or damage of the first signal line and the second signal line (such as: circuit moisture, circuit corrosion, circuit oxidation and/or reduced conductivity) by means of the third signal line and the fourth signal line. possible. In this way, the yield, quality or service life of the touch device can be improved.

In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. The same reference numerals refer to the same elements throughout the specification. It will be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to a physical and/or electrical connection. Furthermore, "electrically connected" or "coupled" may refer to the existence of other elements between the two elements.

It will be understood that, although the terms "first", "second", etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, and/or sections should not be limited by limitations of these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, "a first element," "component," "region," "layer" or "section" discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms, including "at least one," unless the content clearly dictates otherwise. "Or" means "and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. It will also be understood that, when used in this specification, the terms "comprising" and/or "comprising" designate the stated feature, region, integer, step, operation, presence of an element and/or part, but do not exclude one or more The presence or addition of other features, entireties of regions, steps, operations, elements, components, and/or combinations thereof.

Furthermore, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element, as shown in the figures. It should be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. Thus, the exemplary term "lower" may include an orientation of "lower" and "upper", depending on the particular orientation of the figures. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "below" can include an orientation of above and below.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be construed as having meanings consistent with their meanings in the context of the related art and the present invention, and are not to be construed as idealized or excessive Formal meaning, unless expressly defined as such herein.

Exemplary embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments. Thus, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and/or tolerances, are to be expected.

In one embodiment, the touch device 50 may include or be referred to as a touch and cover glass integrated panel (One glass solution Panel; OGS Panel), but the invention is not limited thereto.

In one embodiment, by the above-mentioned method, the touch element and the display element can be integrated, which may be helpful for the realization of the narrow border touch display device.

To sum up, the present invention can reduce the potential difference between the first signal line/second signal line and the adjacent lines when the touch device is used by the third signal line/fourth signal line. Therefore, the possibility of damage or damage to the first signal line and the second signal line (eg, circuit damping, circuit corrosion, circuit oxidation and/or reduced conductivity) can be reduced. In this way, the yield, quality or service life of the touch device can be improved.
