Description

Tactile touch pad using transparent electromagnet film {TANGIBLE TOUCHPAD FABRICATED BY TRANSPARENT ELECTROMAGNET MATRIX FILM}

The present invention relates to a touch panel having a tactile function using a principle of an electromagnet in which magnetic force is induced when a current flows in a conductive coil, and more particularly, includes a spiral transparent electrode rotating at each touch input point. By providing the lower and upper transparent films, the current flows through the coils corresponding to the respective touch input points, thereby forming the magnetic direction of the upper electromagnet film opposite to the magnetic direction of the lower transparent electromagnet film. The present invention relates to a tactile touch pad using a transparent electromagnet film, which is expressed as a three-dimensional protruding cell whose shape can be tactile on a touch panel according to a display form of pictures, letters, and numbers on a touch screen by making mechanical expansion.

A touch panel is a panel that processes a specific function by detecting a location of a user's hand or an object on a character or a specific location on a screen by inputting a function of an input device such as a keyboard or a mouse.

Touchscreen technology is widely used, from PDAs / PMPs, touchpads, and navigation, to haptic phones, where demand is soaring. Devices equipped with a touch panel are portable and easy to operate, which makes them intuitively easy to use.However, improvements in accuracy, speed, character input, and other errors, such as error input, still need to be improved compared to mechanical input devices such as a mouse or keyboard. This exists.

The touch panel is composed of a top plate and a bottom plate (Film or Glass) on which a transparent conductive film {TCO: TRANSPARENT CONDUCTING OXIDE} is deposited. It is responsible for determining the presence of touch input, detecting input coordinates, and transmitting information to the controller. The touch panel is classified into a resistive method, a capacitive method, and an IR method according to the implementation method. A resistive method and a capacitive method are mainly used.

The touch screen panel performs only a passive sensor operation of detecting and transmitting contact information and contact location information, and has only provided a two-dimensional input method.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a user with a three-dimensional shape of a button or a character on a screen, compared to a touch panel which is in charge of a conventional two-dimensional sensor function. Can be recognized by contacting the protruding cell and the individual vibration of each touch input point, and whether or not the key is inputted is determined by the vertical movement of the cell protruding from the upper panel of the touch panel and the vertical vibration of the transparent electromagnet cell by frequency input. The present invention provides a tactile touch pad using a transparent electromagnet film, which provides an active key input method to a user.

Another object of the present invention is to recognize the input of the key and the type of the touched buttons and characters by providing a tactile feeling of the buttons or letters on the touch screen according to the frequency input by the vertical vibration of the individual transparent electromagnet cells of the touch panel. The present invention provides a tactile touch pad using a transparent electromagnet film that provides an active key input method.

Another object of the present invention is a tactile type using a transparent electromagnet film that senses a key input by using a change in current generated when pressing a protruding cell of a touch panel using a transparent electromagnet as a part occupied by a conventional touch panel. To provide a touchpad.

It is configured to include a protective film 105 on the upper side to solve the problem of the present invention.

Further, by further stacking the excitation transparent electromagnet film 101a or the transparent electromagnet glass 101b and the driving transparent electromagnet film, the strength of the transparent electromagnet can be enhanced.

By applying a current to the unit electromagnet coil of the driving electromagnet film 100 and the transparent electromagnet coil of the excitation electromagnet film 101a or the electromagnet glass 101b corresponding to the coil, the corresponding cell of the drive electromagnet film is induced by the induced magnetic force. Through the expansion and contraction action of the upper electromagnet film according to the up and down movement, the touch panel protrudes upward when the positive voltage is applied, and provides a plunging touch when the negative voltage is applied.

That is, the present invention can realize a natural and user-friendly touch and touch pad using a driving transparent electromagnet cell moving at different heights according to the change in the magnitude of the current.

Each cell of the driving transparent electromagnet film 100 is flat in a state where no current is applied, and has the same appearance as a conventional touch pad.

According to the present invention including the above-described configuration, the following effects can be obtained.

The tactile touch pad using a transparent electromagnet film allows the user to contact cells that vibrate three-dimensionally the shape of an image or character on the screen and individual cells that vibrate, compared to a conventional touch panel that only functions as a two-dimensional sensor. By recognizing the key input and transmitting the key to the user through the vertical motion of the cell protruding from the upper panel of the touch panel and the vertical vibration according to the frequency input, an active key input method is provided.
