Abstract

The invention provides an aerial display device and a control method thereof, and relates to the technical field of display. According to the invention, the virtual image is displayed in the air through the display panel, wherein the infrared emitting device emits infrared rays, the infrared receiving sub-pixels receive the infrared rays reflected by an external object so as to detect the coordinate position of the external object, and the processing module determines whether the external object and the virtual image have an overlapped area or not according to the coordinate position of the external object and the coordinate position of the virtual image. A virtual image is displayed in the air through a display panel. The method is based on an infrared transmitting device and an infraredreceiving sub-pixel, detecting the coordinate position of an external object; according to the embodiment of the invention, whether the external object and the virtual image have the overlapped area is determined according to the coordinate position of the external object and the coordinate position of the virtual image, and when the overlapped area exists, it is determined that the touch operation occurs, so that the touch operation can be realized without direct contact with the screen surface of the aerial display device, and the interactive experience of aerial display is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an aerial display device and a control method thereof. Background technique [0002] Aerial imaging technology refers to the direct display of two-dimensional or three-dimensional images in the air without media, and people or objects can directly "pass through" the virtual images displayed in the air, so as to achieve a good interactive and immersive display effect. [0003] However, for the current aerial display device, the displayed virtual image can only be viewed in the air. In the actual operation process, the user still needs to directly contact the screen surface of the aerial display device to realize the touch operation. The interactive experience of aerial display bad. Contents of the invention [0004] The present invention provides an in-air display device and a control method thereof to solve the problem that the existing in-air display device requires a user t...
