Problems solved by technology

[0003] However, in the field of large-screen display, the use of touchpads is relatively seldom. This is because the existing touchpad technology often uses proximity (contact) sensors to realize interactive input, but once the display screen size is too large, the manufacturing difficulty increases. And the cost will rise dramatically

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0037] Such as figure 1 with figure 2 As shown, the interactive display screen should include: a display screen 300 , an imaging device 200 , a light position acquisition device 400 and a processing unit 500 . The imaging device 200 is used to form an image including spatial position information of the object 100 with specific light information. The optical position acquisition device 400 is used to convert the image formed by the imaging device 200 and containing the spatial position information of the object 100 with specific optical information into a corresponding electrical position signal. The processing unit 500 is used for processing the electric position signal transmitted by the optical position acquisition device 400 , and controlling the display screen 300 to make a corresponding display.

[0038] Specifically, the display plan...

Abstract

The invention provides an interactive display screen and an interactive display method. The interactive display screen comprises a display screen (300), an imaging device (200), a light position obtaining device (400) and a processing unit (500), wherein the imaging device is used for forming an image containing a space position of an object (100) with specific optical information; the light position obtaining device is used for converting the image which is formed by the imaging device (200) and contains space position information of the object (100) with the specific optical information into a corresponding position electrical signal; and the processing unit is used for processing the position electrical signal transmitted by the light position obtaining device (400) and controlling the display screen (300) to make a corresponding display. The invention has the advantages that interactive input can be realized without extra demand to the display screen; and the invention is suitable for any display screens such as projection screens, CRT display screens, or the like, thereby realizing the interactive input of a large screen with lower cost.

Description

technical field [0001] The invention relates to an interactive display screen and an interactive display method. Background technique [0002] Interactive input means that the user directly operates in the displayed image, and the corresponding operation of the user can be displayed in time. Interactive input has been applied to various occasions more and more. Among them, the touch panel, as the most commonly used interactive input device, is widely used in PDA, notebook computer, mobile phone, industrial computer, large-screen TV, electronic whiteboard and other fields. Compared with the traditional mouse and keyboard, the operation directly on the display screen by using the touch panel is intuitive and simple, and has been welcomed by people. [0003] However, in the field of large-screen display, the use of touchpads is relatively seldom. This is because the existing touchpad technology often uses proximity (contact) sensors to realize interactive input, but once the d...
