Latest Displays from Tianma Allows Friction and Click Sensation

Press Release Summary:

Tianma’s Displays with Tactile Touch Technology are arranged with multiple electrodes horizontally (X) and vertically (Y) on the glass panel that are applied with voltages of different frequencies to X and Y electrodes. Units provide click feeling by mechanically vibrating the display surface in conjunction with pressing motion and friction variation for texture sensation. The multimodal tactile technology is integrated with different touch feedback effects and rae suitable for in-vehicle displays and industrial devices.

Tianma Introduces New Tactile Touch Technology to Provide Texture and Click Feedback

CHINO, CALIF. (PRWEB) MAY 31, 2018 - The Tianma Group has developed a new tactile touch technology with two different stimulus sources, allowing for both friction and click sensations to be felt by the user.

With this prototype, when users trace an image shown on the display (a button, e.g.), their fingers will sense a rough “texture” feeling. And when users press an image area, they will sense a “click” feeling as if they are pressing a mechanical button. This will allow users to perform a series of operations such as locating and pressing an on-screen button, and then determining an operation without needing to look directly at the display.

Tactile Touch Technology

The display is arranged with multiple electrodes horizontally (X) and vertically (Y) on the glass panel and applies voltage with different frequencies to each X and Y electrode located on the image area. Electrostatic force, corresponding to the difference in the frequencies, occurs at the electrodes’ cross point. When a user traces on the surface, friction variation, modulated by the electrostatic force, occurs. The display uses this friction variation to provide the texture sensation. Furthermore, by mechanically vibrating the display surface in conjunction with a pressing motion, it gives the sense of a clicking feeling as if pressing a mechanical push-button or switch. With this new multimodal tactile touch technology that combines these different touch feedback effects, Tianma offers a user interface with a higher level of functionality and a more realistic sensation than what is available in current touch systems.

The Tianma Group’s new tactile display technology is an ideal solution to facilitate more intuitive and easily operable in-vehicle displays and industrial devices. As an example, this technology enables a standard display to be used comfortably by the visually impaired.
