Tactile input/output device and driving method thereof

Abstract

A tactile input / output device and a driving method thereof are provided. The device includes at least one input end, at least one output end, and a controller. The input end includes a plurality of input cells arranged at regular intervals. The output end includes a plurality of output cells arranged at regular intervals. The controller senses an input signal of the input end and controls the output end to generate a corresponding output signal. The input end and the output end are installed to form one array with being separated. The input cell and the output cell are arranged so that they do not overlap with each other.

Description

technical field [0001] The present invention generally relates to tactile input / output devices for use as data input / output devices in various electronic devices. More particularly, the present invention relates to a tactile input / output device capable of various tactile outputs in response to an input and a driving method thereof. Background technique [0002] In general, many types of electronic equipment with portable terminals include a display as a data output device. Display devices have evolved from earlier black / white liquid crystal displays (LCDs) to high-definition color LCD modules with hundreds of thousands to several million pixels. This is a reflection of the trend toward miniaturization, lightness, and small size while requiring various functions. The display displays data such as general characters and video such as still images, moving images, etc. to the user. [0003] A recent market trend has been data input / output devices with touch screen functionali...

AI Technical Summary

Problems solved by technology

However, this solution limits the expression of tactile sensations that a user can feel with his / her fingertips and provides unsatisfactory results

In addition, the tactile input / output device of the type in which the input sensor is attached to the vibration motor has problems in that it has a limit in reducing the thickness and has poor durability

[0007] In addition, in the case of using the same array address without separating input / output, the control complexity increases, and since the expansion of the sensor array causes an increase in operation, the circuit complexity increases

In addition, since the input on / off switching information is simply controlled through the combination of X and Y axes, conventional sensing technology has difficulty in applying to various input / output schemes
