Mini keyboard of single row push-button and switching method of multiplexing key valve thereof

Abstract

The invention relates to a one-row-key ultra-small keyboard and a method for switching the reuse key values of the keyboard. The keyboard is characterized in that the keyboard adopts the layout of twelve keys in the same row; the keys adopt a capacitance type touch screen; four switchable reuse key values which are a main key value, an upward key value, a downward key value and a number key value are respectively set on each key position. The invention greatly reduces the keyboard size and realizes comfortable and convenient operation by causing one row of keys to play the role of four rows of keys by adopting the method of moving upwards and downwards with fingers and key value switching.

Description

technical field [0001] The invention relates to a microcomputer and an external device of products in the communication field, and more specifically relates to a keyboard and a keyboard control method. Background technique [0002] The rapid development of modern computer technology promotes the popularization of computers, and the trend of miniaturization from desktops to notebooks to handheld computers is increasingly obvious. With the development of miniaturization of computer products, the traditional keyboard design that can input information accurately and quickly is challenged, because the size of the keys must be adapted to human fingers, and the number of characters on the keyboard has also been reduced to Limit, the reduction of the keyboard size is greatly restricted. At present, the design of most microcomputer keyboards is not to reduce the size of the keys at the expense of the convenience of operation, or to reduce the number of keys and then increase the key...

Problems solved by technology

With the development of miniaturization of computer products, the traditional keyboard design that can input information accurately and quickly is challenged, because the size of the keys must be adapted to human fingers, and the number of characters on the keyboard has also been reduced to limit, the reduction of keyboard size is greatly restricted

At present, the design of most microcomputer keyboards is not to reduce the size of the keys at the expense of the convenience of operation, or to reduce the number of keys and then increase the key value through frequent switching operations at the expense of operating efficiency; the keyboard and the touch screen of the microcomputer are combined into one The design can reduce the volume but reduce the effective area of ​​the display
