Problems solved by technology
[0004] There are certain defects in the above-mentioned several methods: in the first way, its production cost is proportional to the size of the required operation interface, and in the case of a large operation interface, the cost is very high; in addition, the capacitive touch screen is based on the current of the human body. It is realized by sensing, and it is generally designed for the user's finger, which is difficult to operate through other media (such as a touch pen, etc.), and the effect is poor when it comes to smooth input of handwritten information
The second way, on the one hand, the radiation is larger, on the other hand, when the required operation interface is larger, the production cost is higher
The third way, relying on the shielding of infrared rays to achieve positioning, determines that its positioning accuracy is very limited in principle, and it is difficult to meet user needs

Embodiments of the present application provide a display device and a screen positioning method. The display device includes: a display screen; a dot matrix layer arranged on the surface of the display screen, the dot matrix layer includes a plurality of code points, and the designated area of the dot matrix layer is used for Reflecting light waves of a preset frequency emitted to the designated area, wherein the light waves emitted by the display screen do not include the light waves of the preset frequency; and a processing unit configured to obtain light waves of a preset frequency reflected from the designated area to generate the target dot matrix image, and determine the position of the specified area on the surface of the display screen according to the target dot matrix image. Through the above design, on the one hand, the production cost and production complexity are reduced, and on the other hand, the positioning accuracy of the display screen is improved.
Description
technical field [0001] The present application relates to the technical field of screen positioning, and in particular, to a display device and a screen positioning method. Background technique [0002] Currently, a touch device can be used to operate the display screen, and the operating position of the touch device needs to be positioned during the operation. In related technologies, there are usually the following implementation methods: [0003] First, use traditional resistive and capacitive touch screens to realize; second, use electromagnetic induction touch technology to realize; third, install infrared emitting and receiving tubes around the operation interface to form crossed infrared rays on the operation interface Matrix, when information is input, if the finger or other medium blocks the infrared rays, that is, the light path is blocked, then the operating position of the finger or other medium on the display screen can be determined according to the detected l...
