Description

Touch keyboard

The invention relates to a touch keyboard, in particular to a touch keyboard with a special arrangement design of a touch sensing unit and a button relative position of the touch sensing area.

In recent years, electronic devices with touch panels are extremely popular. One of the characteristics of the touch panel is that the user slides on the surface of the panel with a finger or a stylus, which can simulate the action of turning pages and changing pages, and when the user wants to input When the text is displayed, a keyboard screen can be displayed on the touch panel. The user can use the finger or the stylus to select the virtual button of the keyboard, which can be used to input text or symbols, but the disadvantage of the virtual button is that the touch is not good and cannot be provided. The elastic touch and realism when pressing the physical button.

Therefore, the industry has developed a touch keyboard with physical buttons. The touch keyboard is composed of a plurality of buttons and a touch sensing unit. At present, there are two ways for the general practitioner to design such a touch keyboard, one for the button. The position is correspondingly set to at least one touch sensing unit, and the other way is to make the touch sensing unit densely discharge, so that each button can correspond to at least one touch sensing unit. In terms of keyboard specifications, it can be divided into three types: English, American, and Japanese. The buttons of the three keyboards are similar. The difference is that the "Enter" key, the "Space" key, the "Shift" key, and the symbol key are different in position or size. As for the numeric keys (such as the numbers 1~10) and the letters (such as the English letters A~Z), the position is fixed. If a touch sensing unit is provided corresponding to the button position, the disadvantage is that the sensing sensitivity is insufficient, and when the pressing position is not accurate enough, the touch sensing unit cannot be correctly sensed. If the touch sensing unit is not densely considered, the button and the touch sensing unit may be misaligned, causing some touch sensing units to fall between the button and the button. It may cause inductive errors and also create a waste of design.
