Abstract
Description
technical field
[0001] The present invention relates to touch technology, in particular to a touch device based on curved surface display and a touch method based on curved surface display. Background technique
[0002] With the progress of science and technology, touch technology has been developed rapidly. Most of the current touch technologies are combined with flat displays, so that users can issue various instructions and perform various operations by touching the display surface. However, the demand for touch operation has been developing in a three-dimensional direction, and the simple plane operation can no longer meet the demand, and the traditional resistive screen or capacitive screen cannot meet the demand for three-dimensional touch operation because it cannot be made into a curved shape. On the other hand, there are currently a small number of curved touch screens, most of which are oversensitive and easily cause misuse. . Contents of the invention [0003...

Embodiment Construction
[0020] Such as figure 1 As shown, it is a block diagram of a touch device based on curved surface display according to an embodiment. The touch device includes a curved projection screen 100 , a contact detection component 200 , a stress sensing component 300 and a main control module 400 . Both the contact detection component 200 and the stress sensing component 300 are connected to the main control module 400 .
[0021] The curved projection screen 100 is curved as a whole and has a certain hardness. The curved surface may be a spherical surface, an ellipsoid, a paraboloid, and other similar regular or irregular curved surfaces with a certain curvature. The curved projection screen 100 has a protruding touch surface 102 and a projection surface 104 opposite to the touch surface 102 . The touch surface 102 can also be called the outside, which is the side that receives the touch of the touch object 900 from the outside. The projection surface 104 can also be called an inne...
