Problems solved by technology

However, this method has a problem in the related art that the vibration force is not uniform across the touch screen panel
In addition, since the installation space of the piezoelectric vibration device is reduced due to the tendency of the area of ​​the touch screen panel to decrease while the number of modules integrated in the board is increased, the size and number of the piezoelectric vibration device are reduced , and thus the vibration may be weak

Abstract

The present invention presents a touch screen device which comprises: a frame; a touch screen panel arranged in the frame; and a piezoelectric vibration member arranged between the frame and the touchscreen panel, wherein the piezoelectric vibration member vibrates in a horizontal direction of the touch screen panel.

Description

technical field [0001] The present invention relates to a touch screen device, and more particularly to a touch screen device in which haptic feedback may exist. Background technique [0002] A liquid crystal display (LCD) has been generally used in various information transmission and audio video (Audio Video, AV) systems. In addition, the touch screen has been applied to the liquid crystal display to facilitate the interface with the driver. The touch screen is designed so that when the screen is touched by using a finger or a stylus, instructions can be executed after detecting a touched portion or a position where a cursor moves. [0003] In addition, the vibration generating device is applied to the touch screen and thereby, enables the user to instantaneously sense feedback vibration for the user's touch input. That is, the vibration generating device disposed in the touch screen device can be used as a means for providing tactile feedback to the user's touch through...
