Problems solved by technology

The technology is thus essentially limited to manufacture and cannot be used as an add-on to existing equipment
Also, a pressure sensing layer with sufficient resolution is quite expensive

Embodiment Construction

[0013] exist figure 1 In the illustrated embodiment, the electronic device 4 is a mobile phone with a capacitive display 1 . The front element of the invention comprises a frame 2 provided with a foil-like surface 3 secured thereto. When placed on the device 4 as a front member, the frame 2 completely surrounds the display screen 1 of the device 4 . Advantageously, frame 2 overlaps the edges of display screen 1 on each side. The height of the frame 2 determines the distance between the foil-like surface 32 fixed to the frame and the display screen 1 . This way there is a certain gap distance between them. This distance may correspond to the height of the frame if the display screen 1 of the device 4 is in line with the part of the housing 5 adjoining it. However, if the latter protrudes from the display screen 1, the gap distance will be correspondingly larger.

[0014] The frame 2 can be connected to this part of the housing 5 in a manner known in the art, for example by...

Abstract

Front member applicable to capacitive display screen (1) panel of electronic devices comprising a fixing element coupled to a screen or to a portion of the casing bordering the screen of the device and a thin, transparent foil-like surface mounted on the fixing element in a given gap distance from the display screen. The foil-like surface (3) is made from a resilient material. When force (F) is applied on a point of the foil-like surface (3) in the direction of the display screen (1) it is able to stretch to form, without permanent deformation, a funnel-shaped elongation (6) within the gap distance (h). The foil-like surface (3) is electrically conductive at least to a certain extent.

Description

technical field [0001] The invention relates to a front member of a capacitive display panel suitable for use in an electronic device, comprising: a fixing element connected to the screen or to a part of a housing adjacent to the screen of the device; and a thin transparent foil-like surface, Mounted to a fixed element with a given clearance distance from the display. The display panel at least includes the display screen, the driving electronic device, the upper protective sheet and the like. Background technique [0002] Currently used capacitive touch screens are known to be difficult to operate through non-capacitive means such as fingernails. This can cause problems, especially in the case of relatively small display screens of mobile phones, but also in the case of other electronic devices, eg cameras, video cameras, GPS devices. [0003] In some schemes, a special pointer called a stylus is used for the touch screen, but it can be easily lost or damaged. [0004] P...
