Problems solved by technology

However, the demand for touch operation has been developing in the direction of three-dimensional, and the simple planar 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 a small number of curved touch screens, most of which are oversensitive, which can easily cause misuse

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...

Abstract

The invention discloses a touch control device based on curved face display. The touch control device based on the curved face display comprises a curved face type projection screen, a touch spot detection component, stress induction components and a main control module, wherein the curved face type projection screen is provided with an outward bulgy touch control face and a projection face opposite to the touch control face; the touch spot detection component is located on one side of the projection face and detects touch spot position data by emitting infrared light to the curved face type projection screen and further receiving the infrared light reflected by a touch object on one side of the touch control face; each stress induction component is used for generating stress data by the time the curved face type projection screen is touched; and the main control module obtains the touch spot position data and the stress data and judges whether the touch control occurs or not. The invention also discloses a touch control detection method applied to the device. With the adoption of the device and the method, the execution of a touch control instruction in the actual occurrence of touch control is guaranteed, so that a contactless type misoperation is prevented.

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...
