Hardware keyboard manufactured based on touch screen technology and realization method thereof

Abstract

The invention discloses a hardware keyboard manufactured based on the touch screen technology and a realization method thereof. The hardware keyboard comprises a touch screen, a touch screen drive IC, a single-chip microcomputer, an FPC, a host computer interface, and an equipment interface, the single-chip microcomputer is connected to an upper terminal via the host computer interface and connected to application equipment via the equipment interface, the touch screen drive IC performs geometric cutting of the touch screen according to keyboard data of the touch screen and determines corresponding area numbers, the area numbers are one-to-one mapping of key codes, and the generated key codes are sent to the application equipment via the equipment interface. According to the hardware keyboard, problems of keyboard design of the overlarge number of keys, variable key numbers, variable key sizes, variable key positions, and variable key shapes are solved, and the hardware keyboard can be widely applied to various touch screen hardware keyboards and the realization method thereof.

Description

technical field [0001] The invention belongs to the field of application of electronic technology, in particular to the field of application of electronic technology of an input interface, and in particular relates to a hardware keyboard made based on touch screen technology and an implementation method thereof. Background technique [0002] The keys and keyboards used in electronic products have experienced several generations of development, and the main difference is in the use of media. In the early days, it was mostly metal elastic contact button type, and later developed a conductive rubber contact type, and then developed a PVC touch keyboard, and in recent years, a touch button based on a touch IC has been developed. [0003] The above four keys and keyboards cannot solve the design problem of a large number of key keyboards: the metal contact type, the conductive rubber contact type, and the PVC touch contact type are limited by the number of CPU (or other IC) pin...

AI Technical Summary

Problems solved by technology

[0003] The above four keys and keyboards cannot solve the design problem of a large number of key keyboards: the metal contact type, the conductive rubber contact type, and the PVC touch contact type are limited by the number of CPU (or other IC) pins when designing a large number of keys. The reason for this limitation is the uncertainty of the number of keyboards and the inconsistency of the fixed number of pins of each CPU (or other IC). At present, a single chip of a touch IC can only do 8 keys at most, and a multi-key keyboard needs to use multiple chips. IC

There is still a very common problem in the current application of touch ICs: the sensitivity of the touch keys is difficult to control, and it is easily affected by the environment and users, and the phenomenon of consecutive clicks and rejections often occurs

As an auxiliary application, it is not a specific electronic product, and there are many limitations in its actual use, neither the look and feel of an independent hardware keyboard, nor the wide application range of an independent hardware keyboard
