With its features of large screen and eye protection, intelligent projection devices have natural advantages over mobile network devices such as mobile phones and tablets in entertainment scenarios such as films and television, and the main purpose of users using projection equipment is to meet entertainment needs such as films and television, so intelligent projection equipment has gradually become an important Internet content platform.

Under the market environment of consumption upgrading, consumers' demand for home audio and video entertainment presents the trend of big screen and pursuing the ultimate experience. Meanwhile, the younger consumption main force makes the consumer market's acceptance of new products greatly increase,

Intelligent projection equipment has become a major market segment of projection equipment by virtue of its high cost performance and portability compared with large-screen televisions and its rapid volume through online channels.

According to the analysis of the competition pattern and Market Development Trend of the projector industry, intelligent projection equipment has become the leading role, and domestic brands are going overseas, which accords with the characteristics of young consumers of projection equipment, convenient transportation of standard products and so on, become the main sales channel of projection equipment manufacturers.

Advantages of projector motherboard solution development

Supports multiple languages for overseas market expansion
Cast a picture size of 1-5.2 M by adjusting the distance to watch a movie
Four-corner trapezoidal correction, can be locked without the trouble of placing position anyway, regular picture
The appearance design of the mini projector, the small figure has a great effect, and you can take it outdoors to enjoy the wonderful vision
Independent and innovative UI design makes the software or web page have aesthetic feeling, and also makes the operation comfortable and simple.
Small screen and large screen, wireless is convenient, support Android, iOS, Mas OS devices HD light and shadow is not limited to real gorgeous more clear
The diffuse reflection imaging principle is adopted, which is different from the direct luminescence principle of traditional LCD TV to reduce eye irritation.
Support trapezoidal correction in vertical direction, household projector can reach -40 ° ~ +40 °, portable projector can reach -15 ° ~ +15 ° correction
Technology is adopted to enhance the reality of the image by adjusting the definition, glossiness and shadow processing, so as to achieve a clear effect comparable to that of the flat panel display device.
The projector adopts the original image identification processor chip technology processing combined with high dynamic contrast display technology to automatically adjust the dark field and details in the image
