Handheld electronic device and outer touch cover thereof

Abstract

The invention provides a handheld electronic device and an outer touch cover thereof. The handheld electronic device comprises a panel and the outer touch cover. The outer touch cover and the panel are oppositely arranged. The outer touch cover comprises an outer cover and a touch sensing structure. The outer cover is provided with a cover body. The touch sensing structure is arranged on the cover body and comprises a plurality of first sensing lines, a plurality of second sensing lines and a medium layer. The first sensing lines are arranged in the first axial direction. The second sensing lines are arranged in the second axial direction. The second sensing lines are located between the panel and the first sensing lines. The medium layer is arranged between the first sensing lines and the second sensing lines. The crossing density, on the upper half part of the outer cover, of the first sensing lines and the second sensing lines is larger than the crossing density, on the lower half part of the outer cover, of the first sensing lines and the second sensing lines.

Description

technical field [0001] The invention relates to a hand-held electronic device and its touch-control outer cover, in particular to a hand-held electronic device and its touch-control outer cover. Background technique [0002] With the continuous advancement of science and technology, various information devices are continuously introduced, such as mobile phones, tablet computers, ultra-thin notebook computers and satellite navigation. In addition to generally using a keyboard or mouse to input or control, using touch technology to control information equipment is a very intuitive and popular control method; wherein, the touch display device has a humanized and intuitive input operation interface, Users of any age group can directly select or manipulate information equipment with their fingers. [0003] In the known handheld electronic devices with touch function, touch operations are performed directly on the panel. However, when performing operations on the panel, fingers m...

[0004] However, this method will increase the size of the electronic device, which goes against the development trend of light, thin, short, and small handheld electronic devices, making it difficult to implement in smaller tablet computers, mobile phones and other products.

In addition, the method of Logitech US Patent No. 5825352 cannot solve the problem of shadowing easily caused by fingers in handheld electronic devices

[0005] In addition, due to the need to touch and operate electronic devices on the panel, the panel is often scratched

In addition, it is known that most of the handheld electronic devices with touch function need to hold the electronic device with one hand and operate on the panel with the other hand. It can only be controlled by the thumb, which is really inconvenient

[0006] Furthermore, when a user uses a handheld electronic device under the bright sun, the sunlight readability of the display panel has always been an issue that cannot be effectively solved, because the user cannot operate the display panel with both hands because the user cannot see the information on the display panel.

[0007] In addition, the touch panel also needs to introduce a rare-earth transparent touch-sensing layer such as ITO to maintain the transparent display performance of the panel. However, due to the increasing depletion of rare-earth metal indium ore, the cost is high; The conductivity is also worse than that of metal, which limits the sensitivity of touch detection, and using a rare earth transparent touch sensing layer as a touch panel is not a good strategy for the sustainable development of the earth's resource ecology and energy conservation; moreover, even if it is not Switching from ITO to a metal grid will also produce metal fringe interference that affects the visibility of the display panel, and relatively reduces the efficiency and convenience of manual operation.

In addition, as the sliding distance of the finger increases with the size of the panel, the area and cost of the touch sensing layer will increase, and the efficiency and convenience of manual operation will also decrease.
