To the current not enough, the utility model provides a keyboard with handwriting function and typing integral type.
The utility model provides a technical scheme that its technical problem adopted is:
a keyboard with a handwriting function comprises a keyboard body, wherein the keyboard body is provided with a key module and a touch module, the touch module comprises a cholesterol liquid crystal display film and an EMR display film, the EMR display film is attached below the cholesterol liquid crystal display film, the upper surface of the keyboard body is provided with a through hole, and the touch module is installed in the through hole; the keyboard body is internally provided with a PCBA board which is electrically connected with the cholesterol liquid crystal display film and the EMR electromagnetic film.
As a preferred mode, the keyboard body is further provided with an electromagnetic pen which is matched with the keyboard body for use.
Preferably, the keyboard body includes an upper cover and a lower cover that are engaged with each other.
Preferably, a bracket for supporting the touch module is arranged on the lower cover.
Preferably, the EMR electromagnetic film, the cholesteric liquid crystal display film and the through hole have the same shape and size.
The utility model has the advantages that: the utility model organically combines the handwriting board and the keyboard together, cancels the original touch board mode, uses the EMR electromagnetic film to electrically connect the PCBA board, realizes the position movement of the mouse on the computer display screen through the sliding of the external electromagnetic pen, thereby realizing the function of touch sliding; a liquid crystal cholesterol display module is arranged above the EMR module, writing contents can be visually displayed through writing of an electromagnetic pen, and the contents displayed on the liquid crystal cholesterol film can be cleared by starting a corresponding software program, so that repeated writing is realized, and when a user needs to type, the same operation through the software program is switched, and the efficiency of the user is improved.
