Embodiment Construction
[0020] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.
[0021] A full-keyboard mobile phone of the present invention includes a circuit board with a full-keyboard function. In one of its specific implementations, the buttons on the circuit board with similar positions are arranged in partitions, and the buttons between the partitions form a positional relationship; the buttons in the same partition Located on the same KROW row line of the matrix schematic diagram, the buttons with corresponding positions are located on the same KCOL column line of the matrix schematic diagram; the first layer of the circuit board is laid out The connection between the buttons in the same partition, The second layer of the circuit board la...

Disclosed are a circuit board having a full keyboard function, a full keyboard mobile phone, and a layout and wiring method of a keyboard thereof. Keys on the full keyboard are partitioned according to a position approximation principle, so that position correspondence is formed between the partitioned keys; keys in the same partition area are allocated on the same row line of a schematic matrix diagram, and keys having position correspondence are allocated on the same column line of the schematic matrix diagram; wiring between the keys in the same partition area is disposed on a first layer of the circuit board, and wiring between the keys having the position correspondence are disposed on a second layer of the circuit board. The means of partitioning keys of approximate positions and forming position correspondence between partitioned areas is adopted, keys in the same partition area are allocated on a column line, and keys of the position correspondence are allocated on a row line, so wiring between all keys on a column line and a row line is implemented in two circuit board layers, thereby saving more circuit board spaces and layers, and improving EMC and EMI performances of a mobile phone.
Description
technical field [0001] The invention relates to the field of mobile communication terminals with a full keyboard, and more specifically, the improvement relates to a mobile phone with a full keyboard and a keyboard layout and connection method thereof. Background technique [0002] Today's mobile terminals tend to develop toward intelligence. Most of the smartphones are full-keyboard mobile phones, in order to bring users the best input experience. At the same time, smart mobile terminals are also developing in the direction of multi-function and miniaturization. Integrate many functions, such as large screen, WIFI, Bluetooth, GPS and other functions. It is bound to require mobile phone designers to design more and more dense layouts and connections on a limited circuit board, and these connections must not only complete the function, but also must be able to meet the performance requirements of EMC and EMI. It can be seen that the keyboard in a full-keyboard mobile phone ...
