Projection display equipment achieving touch interaction

Abstract

The invention discloses projection display equipment achieving touch interaction. The projection display equipment comprises a touch display device, a communication device and a projection device which are electrically connected in sequence. The touch display device comprises a touch layer for inducting the position of a touch point, an optical display film for receiving projection information anddisplaying information content, and a first fit adhesive layer for ensuring stable fit of the touch layer and the optical display film. The communication device comprises a signal converting unit forconverting capacitance value detecting signals of RX and TX into USB signals and a USB bus. The projection device is an ultra-short focus projector. By means of the design, the projection display equipment is convenient to control, simple in interaction and high in touch precision.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a touch-interactive projection display device. Background technique [0002] Projection display technology has been very mature. In today's society, people's dependence on projectors has become stronger, their understanding of projectors is getting deeper and deeper, and their requirements for projectors are getting higher and higher. There are many advantages, but there are also some disadvantages: such as troublesome operation, cumbersome interactive machinery, and some user scenarios need to find the remote control to operate; for example, when our display device is hoisted, we must use the remote control, step by step according to the menu Step by step operation. In order to solve this problem, projection display devices with touch interaction functions have been launched on the market. Users can directly touch the display area to complete flat interactive op...

[0002] Projection display technology has been very mature. In today's society, people's dependence on projectors has become stronger, their understanding of projectors is getting deeper and deeper, and their requirements for projectors are getting higher and higher. There are many advantages, but there are also some disadvantages: such as troublesome operation, cumbersome interactive machinery, and some user scenarios need to find the remote control to operate; for example, when our display device is hoisted, we must use the remote control, step by step according to the menu step by step operation

In order to solve this problem, projection display devices with touch interaction functions have been launched on the market. Users can directly touch the display area to complete flat interactive operations; In the existing technology, the touch coordinates are usually obtained by combining infrared light with a camera. This method is not suitable for rear projection, and the front projection is also blocked, resulting in low touch accuracy.
