Mobile phone device and realization method thereof

Abstract

The invention relates to the field of touch keys, in particular to a mobile phone device and a realization method thereof. The mobile phone comprises a resistive touch screen, four coordinate electrodes, an upper row of touch keys, a lower row of touch keys and a four-pin connector, wherein the four coordinate electrodes are arranged around the resistive touch screen and comprise an X+ electrode,an X- electrode, a Y+ electrode and a Y- electrode; the upper row of touch keys is arranged by extending the resistive touch screen; the lower row of touch keys is arranged on the side edge of the resistive touch screen; and the four-pin connector is arranged on the side edge of the lower row of touch keys. In the mobile phone device and the realization method thereof, the area of the resistive touch screen is extended by using the principle of resistive touch, and a special folded wiring mode is added. Not only the design of touch keys near an antenna area is realized, but also antenna performance is ensured, the design reliability and the rick controllability are increased, the price is cheaper, and the backlight of the key area is easier to design.

Description

technical field [0001] The invention relates to the field of touch buttons, in particular to a mobile phone device and an implementation method thereof. Background technique [0002] With the development of communication technology, the use of mobile phones is becoming more and more popular. At present, the commonly used touch button technologies in mobile phones generally include resistive, capacitive and so on. [0003] Most of the touch buttons in the prior art use capacitive touch buttons, but since the capacitive touch buttons are easily disturbed by the surrounding environment, the requirements for structural space, hardware wiring and ground plane are relatively high during design. If this The touch button area is close to the antenna, and it is easy to interfere with the antenna, and under the product definition with large rounded corners, there are multiple touch area functions, and in the design near the antenna area, the design of the touch button is very difficu...

[0003] Most of the touch buttons in the prior art use capacitive touch buttons, but since the capacitive touch buttons are easily disturbed by the surrounding environment, the requirements for structural space, hardware wiring and ground plane are relatively high during design. If this The touch button area is close to the antenna, and it is easy to interfere with the antenna, and under the product definition with large rounded corners, there are multiple touch area functions, and in the design near the antenna area, the design of the touch button is very difficult, which cannot be achieved in the prior art Overcoming Disadvantages of Interfering Antennas
