Large screen high-precision frameless touch scheme

  1、 Introduction to laser large screen frameless high precision scheme: The laser touch interactive module can be combined with any screen (such as projector, LED screen / floor tile screen, splicing screen, transparent screen, holographic screen, etc
) to turn the ordinary display screen into a large touch screen with high precision, large picture and no frame It can be used in exhibition halls, exhibition halls, science and technology museums, art galleries, multimedia conference rooms, multi-functional teaching, new retail, children's entertainment and other fields 2、 Core advantages: Large screen: support 3 * 36m large screen touch High accuracy: the touch accuracy can reach 2mm, which can reach the writing accuracy No border: the two sensors are only fist size and have no border 3、 Technical introduction: The laser touch interaction module is simple in structure and consists of two parts: laser transmitter and signal receiver camera
The laser transmitter is installed on any screen (projection screen, LED screen, LCD splicing screen, etc
), forming an invisible light film 1-2mm higher than the surface and about 1mm thick on the screen surface
When the finger or any opaque object contacts the surface, the light is reflected on the image sensor (camera) set above the screen, and then the coordinates of the mouse are obtained through the accurate calculation of the photoelectric position 4、 Introduction to application fields 1 Conference room scheme 1: projector + laser touch module: at present, the projector is still the mainstream display equipment in the conference room
Touch all-in-one machines are gradually adopted for products below 80 inches, but for products above 100 inches, the price of touch all-in-one machines is very expensive
The easy to see laser touch scheme can realize 2mm accurate large screen borderless touch control for any 100-500 inch projection screen Scheme 2: LED large screen + laser touch module With the popularity of large LED screens with small spacing, more and more conference rooms / lecture halls use large LED screens, the main size is between 120-200 inches
This size uses infrared frame to realize touch control, which is relatively expensive and complex in installation and maintenance Using laser interactive technology: 1: 100% frameless touch, more beautiful 2: The volume is light, and only two sensors the size of a fist need to be installed, which is simple to install 3: Any screen can be applied without customization Scheme 3: splicing screen + laser interactive module 1
Interactive technologies such as multimedia exhibition hall, multi-functional teaching, immersive restaurant and KTV include radar and laser interactive technology
Radar technology: 1
Unable to achieve precise interaction, 2
Complex installation and commissioning: manually select the interactive area and manually locate 3
High maintenance cost: after the projector is moved, there is a deviation in positioning, so technicians need to be sent for debugging and maintenance Laser interactive technology: 1: Automatically select the interactive area 2: Automatic positioning 3: Maintenance free, external physical keys can be used to realize one key correction without technical door-to-door maintenance and save cost 2
Multifunctional teaching Compared with the traditional single screen projection solution, if you want to realize the immersive experience, you need to wear VR glasses, which can not realize the interaction of multiple people
Now the multi projection immersive interaction solution can lose VR glasses and involve multiple people 3
New retail / cloud shelf applications Save store space, and more products can be displayed in small stores Orders can be placed online to save store operating costs Precise touch scheme: infrared touch frame and laser interaction Infrared frame: 1
The appearance is not enough, and the screen has a black frame 2
High cost 3
Trouble in installation and commissioning, manual calibration
Laser interaction 1
Beautiful, 100% borderless interaction 2
A single set can realize 3M * 4
5m interaction, and the 6-level connected screen supports 3 * 30m precise touch control 3
2mm high precision touch 4
Automatic positioning, completed in 5 seconds, easy to install and debug 4
Sports Interaction Sports interaction, such as basketball, volleyball, archery, etc
the interaction is realized by hitting the ball or arrow on the screen Because the speed of hitting the ball is very fast, the frame rate of radar interaction is only 40 (the frame rate is the number of screen shots per second), and there is often a missed hit rate, while the laser interaction technology can reach 120 frame rate, which can record the hit rate of 100% 6、 Laser interactive technology + infrared laser pen to achieve long-distance space-apart precise touch , It can be used in conference rooms, multimedia exhibition halls, exhibition halls, science and technology museums, children's entertainment and other fields
The product form can design different appearance according to the application field
It can support several meters of remote operation
