Abstract

The invention discloses an interactive display screen. The interactive display screen comprises a printed circuit board, a first light-emitting unit, and a control unit; the first light-emitting unit is used for providing a display image; the control unit is formed on the printed circuit board and is coupled with the first light-emitting unit to control the first light-emitting unit; the interactive display screen also comprises a second light-emitting unit, an optical sensing unit, and a processing unit; the second light-emitting unit is used for providing detection light; the optical sensing unit is used for receiving optical parameter variation of the detection light which is initiated through touch to acquire touch data; and the processing unit is coupled with the optical sensing unit to determine a touch position by using the touch data and send the touch position to the control unit. The invention also discloses an interactive projection screen. The gap of touch screen technology in the application field can be filled.

Description

technical field [0001] The invention relates to the field of interactive display, in particular to an interactive display screen and an interactive projection screen. Background technique [0002] At present, display screens have been widely used in various industries. In order to further improve the practicability of display screens, people generally add touch screens to the display screens to realize human-computer interaction functions. Today, touchscreen technology is used in a variety of new technologies, including video game systems, computers, and devices that include electronic music. However, there are still a few areas of display technology (such as electronic signage and optical projection) that have not involved touch screen technology and need to fill in the gaps. Contents of the invention [0003] The purpose of the present invention is to provide an interactive display screen and an interactive projection screen to fill the gap in the application field of t...
