Problems solved by technology

[0003] However, if the existing electric field tactile feedback technology is applied to a curved touch screen, the intensity of the induced electric field will vary due to the thickness of the insulating layer on the surface of the touch screen, so that when the finger touches the curved touch screen, Inability to get the same haptic feedback at different locations on the surface

Embodiment Construction

[0046] Figure 1a It is a structural schematic diagram of a curved touch screen with tactile feedback. Figure 1b yes Figure 1a The equivalent circuit diagram of the haptic feedback touch screen.

[0047] Such as Figure 1a As shown, a curved tactile feedback touch screen 10 includes an insulating layer 11 made of glass or plastic, a transparent conductive layer 12 composed of a plurality of transparent electrodes, and a power module 13 providing a driving voltage. The insulating layer 11 has an upper surface 11a and a lower surface 11b. The upper surface 11 a is a curved surface protruding from the central area, and this curved surface is the touch surface of the touch screen 10 for finger contact. The lower surface 11b is a plane covered with a transparent conductive layer 12 formed by a plurality of transparent electrodes.

[0048] When the finger touches the tactile feedback touch screen 10, the power module 13 will output a driving voltage of a predetermined value to t...

Abstract

The invention provides a curved surface touch feedback touch screen and a touch feedback driving method thereof. The curved surface touch feedback touch screen comprises an insulating layer, a transparent conducting layer and a power module. The insulating layer is provided with a curved upper surface and a flat lower surface, and the upper surface is used as a touch plane. The transparent conducting layer is paved on the lower surface and is provided with a plurality of transparent electrodes. The power module outputs driving voltage to the transparent conducting layer to enable electric field intensity at different positions on the touch plane to be roughly same.

Description

technical field [0001] The present invention relates to a tactile feedback touch screen and a driving method thereof, and in particular to a tactile feedback touch screen capable of obtaining the same tactile feedback at every position on a curved touch surface and a driving method thereof. Background technique [0002] Today, touch screens are widely used in various devices, such as smart phones or tablet computers. In order to increase the sense of reality of the user operating the touch screen, a touch screen with a tactile feedback function is proposed. Haptic feedback technologies include vibrating haptic feedback using small motors or piezoelectric elements, and haptic feedback using electric fields to control the friction between the finger and the touch surface. [0003] However, if the existing electric field tactile feedback technology is applied to a curved touch screen, the intensity of the induced electric field will vary due to the thickness of the insulating ...
