A small device of this type may have keys to control the device. Each key is provided with at least one function related to the device. At present, the button function is achieved by two different structures. In the first form, a micro switch is set on each circuit board (which is in contact with the LCD module), and the micro switch is mechanically controlled by the corresponding side key to directly contact the key function. In the second form, the key function is achieved by a separate small circuit board (which is fixed in the housing of the LCD module). When developing a small device of the form described above, it is important to construct a device that is as small and portable as possible. This will save space as much as possible and ergonomically integrate the keys into the entire device. The present invention is to make the side keys as ergonomically added to the entire device as possible to save space as much as possible. This purpose is achieved by stringing the LCD module of the first scope of the patent. Other advantageous forms are described in the subsidiary items of the scope of patent application. An LCD module is provided according to the first patent scope of the present invention, which includes at least the following components: a) LCD b) this LCD | 1: carrier, c) a device arranged on the side of the module Key, d) a "mt" foil is used to achieve the key function.

Description of the invention (2) For example, it can be glued on the carrier or applied to the carrier in other ways. In addition, this carrier can also dominate a card slot mechanism, by which the LCD card can be snapped in and can carry or support the LCD. The contact foil relates to a flexible circuit board or a fixed circuit board. In a preferred embodiment of the LCD module of the present invention, the 'contact foil is provided with at least one metal dome. In another preferred embodiment of the present invention, the contact foil comprises a poly dome foil. This polymeric dome has a stone carbon version. A rubber with a carbon version can also be used. Different foils have different tactile sensations to the user. In another preferred embodiment of the LCD module of the present invention, the carrier for the LCD can be used as a light guide. One surface or multiple surfaces are provided on the light guide of the LCD module. The form of these faces can be adjusted according to circumstances and needs, ie they can be flat or curved, for example. The contact foil is then applied to these faces. If a corresponding snap-in element is provided, the contact foil can be stuck and stuck, or the contact foil can be fixed by a clip. As described above, if a metal dome is provided on the contact foil, the open contact area on the contact foil can be closed thereby. The keys that can be operated by the user of the device are pressed against the metal dome, and the above-mentioned contact effect can be triggered by the operation of each key, so the key function can be achieved. Since the carrier for LCD can also be used as a carrier for contact foil, and therefore can automatically form the opposite support required by the user's key force, the maximum space requirement can be reduce. The keys can therefore be integrated as ergonomically as possible in a space-saving manner. The base is for accommodating the LCD and the light guide can be accommodated when needed, wherein the contact foil is directly arranged on the frame base. In this embodiment, the 'frame base is used as a carrier for this contact foil and thus forms the opposite support needed for the key force. In this embodiment, due to the frame base provided, the required space is larger than the aforementioned The implementation forms are slightly larger, but according to the requirements set for this device, various high stability-and strength requirements can be formed. Among them, this implementation form with a frame is more advantageous. In this regard, it must be known whether the stability requirement or the size of the device should be given priority in special cases.
