Description

BACKGROUND OF THE INVENTION

field of invention

The invention relates to an electronic device, and in particular to a touch-sensitive device.

Description of the prior art

A touch device (such as a touch panel) has the advantages of convenient operation and is therefore widely installed in electronic products (such as mobile phones, tablet computers, electronic boards, etc.). The touch device includes a plurality of first touch electrodes and a plurality of second touch electrodes interleaved with each other. Based on the consideration of visual effects, the first touch electrodes and the second touch electrodes are typically implemented mainly as transparent scan patterns. The resistance of the transparent sensing patterns is high, which is not conducive to the electrical properties of the touch device. Therefore, mesh-shaped first touch electrodes and second touch electrodes made of low-resistance materials (e.g., metals) have been developed.

Compared to transparent scanning patterns, the mesh-shaped first touch electrodes and second touch electrodes are more suitable for application in a large-sized touch device (such as an electronic board, etc.). An edge-induced electric field may be formed between the first touch electrodes and the second touch electrodes to detect if there is a conductive object (such as but not limited to a finger, stylus, etc.) touching the touch surface or itself you approach In general, the distance between the touch surface and the first touch electrodes and the second touch electrodes is larger in a large-sized touch device, so the lines of force of the edge-induced electric field have insufficient distribution density on the touch surface, affecting the performance of the touch device.

DESCRIPTION OF THE EMBODIMENTS

Exemplary embodiments of the invention are described in detail below, and examples of the exemplary embodiments are conveyed with reference to the figures. Wherever possible, the figures and the descriptions use the same reference numbers to refer to the same or like sections.

It should be understood that when a layer, film, region or device of a substrate is on top of another device or is "connected" to another device, the device is directly on top of the other device or connected to the other device or there may also be an intermediate device. On the other hand, if a device is "directly on top of another device" or "directly connected to" another device, an intermediate device does not exist. As used in the present specification, "connected to" may refer to a physical and/or electrical connection. Additionally, "electrically connected" or "coupled" may mean that other devices are present between two devices.

"Approximately", "similarly" or "substantially", as used in the present description, includes the value and the average value within an acceptable deviation range of a certain value, which is confirmed by persons skilled in the art, and the relevant measurement and a certain quantity (i.e. Limitations of the measurement system) of measurement-related errors are taken into account. For example, "about" can mean within one or a plurality of standard deviations of the value, or within ±30%, ±20%, ±10%, or ±5%. Additionally, as used herein, "approximately," "similar," or "substantially" may include a more acceptable range of deviation or standard deviation according to optical properties, etch properties, or other properties, and one standard deviation need not apply to all properties.

Unless otherwise indicated, all terms (including technical and scientific terms) used in this specification have the same definition as commonly understood by those skilled in the art. It should be further understood that the terms defined in commonly used dictionaries are to be interpreted as having the same definitions throughout the prior art and throughout the description of the invention, and are not to be construed as ideal or overly formal definitions, unless clearly indicated as such in the present specification.

With reference to 1 , 3 and 4 It should be noted that since the first touch electrodes 112 have the first arms 112c and the second arms 112d, a horizontal distance S1 (marked in 3 ) between the first arms 112c or the second arms 112d of the first touch electrodes 112 and third main portions 132a or fourth main portions 132b of the second touch electrodes 132 is smaller than a horizontal distance S2 between the first main portions 112a or the second main portions 112b of the first touch electrodes 112 and the third main portions 132a or the fourth main portions 132b of the second touch electrodes 132; in other words, the distance between the first arms 112c and/or the second arms 112d of the first touch electrodes 112 and the third main portions 132a or the fourth main portions 132b of the second touch electrodes 132 is short; therefore, the first branches 112c and/or the second branches 112d of the first touch electrodes 112 contribute to pushing the lines of force of the edge-induced electric field between the first touch electrodes 112 and the second touch electrodes 132 toward the touch surface 10a, thereby increasing Cm% and Cm% related performance of touch device 10 is improved (for example, but not limited to: touch sensitivity), where Cm%=[(Cm-Cm')/Cm]*100%, where Cm is the sensing capacitance of the first touch electrodes 112 and the second touch electrodes 132 when no conductive object (not shown) is provided on the touch surface 10a, and Cm' is the sensing capacitance of the first touch electrodes 112 and the second touch electrodes 132 when a conductive object (not shown) is on the touch surface 10a is provided.
