A 4k ultra-high-definition display touch electronic whiteboard

Abstract

The invention discloses a 4K ultra-high-definition display touch electronic whiteboard, which relates to the field of electronic whiteboards. The invention sets an infrared emitter to include a first infrared emission probe, a second infrared emission probe and a third infrared emission probe, and makes the first infrared emission probe There is an inclined angle a between an infrared emitting probe and the second or third infrared emitting probe, so that the infrared rays emitted by the infrared can be emitted from different angles, ensuring the receiving accuracy of the infrared receiver and improving the touch control The accuracy of recognition when writing on the electronic whiteboard ensures smooth writing; the infrared multi-touch electronic whiteboard of the present invention cooperates with a 4K laser projector to achieve precise positioning and smooth writing in a high-definition environment, ensuring quality and master control The device can automatically adjust the emission power of the infrared emitter according to the detection value of the light intensity detection probe, effectively guarantee the writing efficiency, improve the writing accuracy and sensitivity, and reduce energy consumption.

Description

technical field [0001] The invention relates to the field of electronic whiteboards, in particular to a 4K ultra-high-definition display touch electronic whiteboard. Background technique [0002] With the development of computer technology and electronic technology, there has been an electronic product that can combine the functions of a computer and a projector: an electronic whiteboard; because there are several electronic devices, such as electronic chips, etc. installed in the electronic whiteboard, it can be timely and convenient. Flexibly introduce various types of digital information resources to make the display of digital resources more flexible, and can also realize the function of instant storage of blackboard content, which is convenient for future use; precisely because of its many advantages, electronic whiteboards are widely used as teaching and training equipment. More and more widely used; With the increasing development of electronic whiteboards, touch elec...

AI Technical Summary

Problems solved by technology

[0003] There are usually two installation methods for common touch electronic whiteboards, one is wall-mounted, and the other is bracket-mounted; due to different workplaces, the installation requirements of touch electronic whiteboards are also different. Common touch electronic whiteboards Unable to adjust according to the installation site, which brings some troubles to the use of touch electronic whiteboards; the volume of electronic whiteboards is generally large, which makes moving and handling very troublesome; touch electronic whiteboards have poor protection and are vulnerable to external impact the destruction of

More importantly, the current touch electronic whiteboards are not clear enough to write smoothly, especially when the light intensity is high, the writing angle is not good, and the writing is fast, which will lead to intermittent writing records and inaccurate positioning , it is difficult to achieve better writing effect
