Problems solved by technology

However, a uniform conductive layer pattern is matched with a cover plate with uneven thickness. The thicker the cover plate, the smaller the signal volume, which will cause uneven signal volume and become a flaw in the hardware. Even if it is optimized by algorithm or software, it is impossible. There is a big improvement

Embodiment Construction

[0030] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. In the various figures, identical elements are indicated with similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale. Also, some well-known parts may not be shown in the drawings.

[0031] By simulating the capacitance of touch devices with different cover thicknesses, it is found that as the thickness of the cover increases, the original mutual capacitance value will also increase. When the cover reaches a certain thickness (between 0.5-7mm), the mutual capacitance The value increase is very small, an increase of only 0.04pF. As the thickness of the cover plate increases, the mutual capacitance value of the copper pillars increases, the variation of the capacitance first increases (in the range of 0.05-0.125mm) and then decreases, and the signal amount (the ratio of the variation to the original valu...

Abstract

The invention discloses an electronic device. The electronic device comprises a touch device and a cover plate arranged on the touch device and nonuniform in thickness. The touch device comprises a patterned conductive layer, wherein the pattern coupling property of the patterned conductive layer is matched with the thickness of the cover plate to make electric output characteristics of the touch device uniform. The pattern coupling property of patterns of the conducive layer regularly changes with the changing thickness of the cover plate by correspondingly designing different conductive layer patterns at different thicknesses of parts of the cover plate, so that the whole capacitance value and signal quantity of the touch device in the electronic device are more uniform.

Description

technical field [0001] The present invention relates to the technical field of touch control, and more particularly relates to electronic equipment including a touch control device. Background technique [0002] The common electronic devices with touch function on the market usually include a touch device 2 and a cover 1 arranged above the touch device. The cover 1 generally has a fixed thickness, and the typical thickness of the cover 1 is mostly 0.7 mm or 1.1 mm. ,like Figure 1a shown. With the popularity of electronic devices such as wearable watches and bracelets, some cover designs with non-uniform thickness have emerged in the touch panel market. structure, such as Figure 1b shown. For example, in order to improve the overall visual effect of the screen and the fuselage, and at the same time enhance the feel, the mobile terminal industry has gradually begun to adopt touch screens with various surface structures, such as curved screens and curved screens. Figure 2...
