Computer projector with built-in lithium battery and virtual electronic whiteboard for android system

Abstract

The invention discloses a computer projector with a built-in lithium battery and a virtual electronic whiteboard for an android system. The computer projector comprises a projector, a projection screen, an electronic pen, a CMOS (complementary metal oxide semiconductor) camera, an image processor, a CPU and the built-in lithium battery, wherein a computer partially supports android software and is provided with VGA (video graphic array), AV (audio video) and HDMI (high-definition multimedia interface) input ports, the information is sent into a video information processor, the processed information is sent to the CPU, the CMOS camera is connected with the image processor to form the virtual electronic whiteboard, the image information processed by the image processor is sent to the CPU, the CPU is connected with an LED drive module which is connected with an LED light source system, the CPU is connected with a DMD (digital micromirror device) drive model to transmit information to the LED light source system, the DMD drive model is connected to the projection camera to present the projection image, the CPU is connected with a wireless module to implement WIFI (wireless fidelity) wireless transmission, a computer system supports the running of the android system software, and the built-in lithium battery or an externally power source is used for providing electricity.

Description

technical field [0001] The invention belongs to projection devices. Specifically, it relates to an Android system computer projector with a built-in lithium battery and a virtual electronic whiteboard. Background technique [0002] In today's information age, computers, projectors, and virtual electronic whiteboards are widely used in conference speeches, scientific research and teaching, and business activities.

Problems solved by technology

In 2011, our company applied for a utility model patent for a miniature projector with a computer, the patent number: ZL201120179541.7, which is the integration of a computer and a projector. In 2012, our company applied for a computer with a virtual electronic whiteboard Projector, patent application number: 201220304999.5, the above patent only realizes a micro computer projector with a virtual electronic whiteboard. With the development of optoelectronic technology, the market demand is all-round. At present, the defects of domestic micro projectors are: ( 1) There is no lithium battery power supply part in the machine, and it needs to be powered by an external power supply when using it. When students and children are engaged in large-screen interactive learning and games, it cannot ensure safety and is inconvenient; (2) It cannot be used exclusively for Android system software. Innovative design is imperative
