Portable projector based on mobile interconnection

Abstract

The invention discloses a portable projector based on mobile interconnection. The portable projector comprises a central processing unit, a 4G module unit, a high-capacity battery unit, a battery management unit, an LED (Light Emitting Diode) light machine unit, an LED driving power supply unit and a DLP (Digital Light Processor) unit. The 4G module unit is additionally arranged in the portable projector disclosed by the invention; the projector can continuously provide services without a wireless network; users can access required information at any time, such that the user experience is improved; the high-capacity battery unit is additionally arranged; therefore, autonomous power supply of the projector can be realized; the portability and the practicability of the projector are improved; the DLP unit and the LED light machine unit are utilized; display of a high-definition picture is realized; the picture output quality of the projector is improved; various interfaces are provided, such that the expansibility of the projector is improved; a fan unit is additionally arranged, such that the heat dissipation function of the projector is enhanced; a power amplifier unit and a loudspeaker unit are also additionally arranged; therefore, the realistic sound effect is provided; and the play effect of the projector is enhanced. The portable projector based on mobile interconnection disclosed by the invention can be widely applied in the field of projection.

Description

Technical field [0001] The invention relates to the field of projection, in particular to a portable projector based on mobile internet. Background technique [0002] DLP: the abbreviation of DigitalLightProcession, which is digital light processing. [0003] I2S (Inter-ICSound) bus, also known as integrated circuit built-in audio bus. [0004] I2C (Inter-IntegratedCircuit) bus is a two-wire serial bus developed by PHILIPS Company, used to connect microcontrollers and their peripheral devices. [0005] A projector, also known as a projector, is a device that can project images or videos onto the screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0006] In the prior art, the projection equipment has the following def...

AI Technical Summary

Problems solved by technology

[0007] 1. The video signal must be provided through a wired network, which cannot realize wireless control and signal transmission, and cannot experience the information sharing and real-time interconnection brought by the massive resources in the wireless cloud resource library;

[0008] 2. Existing projection equipment generally needs to be connected to a power source to start working normally, and cannot be truly portable, and cannot follow-up with the broadcast without an external power supply;

[0009] 3. Poor audio and video processing capabilities lead to poor viewing effects
