Embodiment Construction

[0026] Below is the specific embodiment of the present invention to further describe:

[0027] The invention discloses a capacitive touch flexible keyboard, which includes the following features: image 3 As shown, the first PET and electrode layer 21, the second adhesive layer 22, the third protective decoration layer 23, and the flexible circuit board 24 can be bent.

[0028] The first PET and electrode layer 21 are transparent conductive optical materials, and the substrate is polyethylene terephthalate, on which the conductive material indium tin oxide is sputtered and covered. The thickness of the PET substrate in this embodiment is 100um. The first The PET and electrode layer 21 are placed at the bottom of the entire product design as the base layer and functional layer.

[0029] The first PET and the ITO on the upper surface of the electrode layer 21 are designed with a keyboard touch function pattern 31 , and the entire function pattern 31 is composed of multiple grou...

Abstract

The invention relates to a capacitive touch type flexible keyboard, belongs to the field of external input equipment and particularly provides a capacitive touch type flexible keyboard based on a touch screen manufacture technology. The capacitive touch type flexible keyboard comprises a first substrate and electrode layer (21) on the bottommost layer, a second glue layer (22) and a flexible printed circuit board (24), wherein one side of the second glue layer (22) is attached to the upper surface of the first substrate and electrode layer (21), and the other side of the second glue layer (22) is attached to the lower surface of a third protective and decorative layer (23). The capacitive touch type flexible keyboard is characterized in that a keyboard touch function pattern (31) is arranged on the upper surface of the first substrate and electrode layer (21), one end of the flexible printed circuit board (24) is in conductive connection with the keyboard touch function pattern (31) on the upper surface of the first substrate and electrode layer (21), the other end of the flexible printed circuit board (24) is in conductive connection with a mainboard, and the keyboard can be bent. The capacitive touch type flexible keyboard has the characteristics that the structure is simple, functions are easy to realize, the product is thin, light in weight, bendable, portable and the like, and can be made into an optical transparent keyboard.

Description

technical field [0001] The invention relates to a capacitive touch flexible keyboard, which belongs to the field of external input devices, in particular to a capacitive touch flexible keyboard. Background technique [0002] As a connection method for man-machine dialogue, the keyboard is widely used in computers, mobile phones or other terminal equipment, and communicates with the host computer through a wired or wireless interface. With the rapid development and popularization of electronic products, the keyboard has become an indispensable tool in daily life and work. [0003] However, the current physical keyboard is generally composed of plastic, encoder and circuit board, and its structure is heavy and not easy to carry. Most of the current flexible keyboards use screen printing to print the conductive layer of the metal circuit, and use scanning to confirm the position coordinates. This kind of flexible keyboard is not suitable for long-term use because of its metal...
