Compact device is equipped with a matrix (1280 x 800 pixels). The HD 1500:1. Power flood light 700 lumens. The range projection of 0.55 – 3.22 meters. Diagonal images may vary in the range of 0.43 – 2,53 m Has a 1.2-fold optical zoom. The supported transmission formats of pictures 16:10, 16:9, 4:3. There is a possibility of correction of images (up to 40 degrees). In the device there is front and rear projection.
The advantages of using projectors
The main advantage is the mobility of the device, less strain on the eyeballs of the user, as light is directed on the screen, the user sees the reflection of the light flux from the device.
The main advantages of modern devices:

The main advantages of modern devices:
- Life span of light source is about 20 – 30 thousand hours. Depending on the degree of wear observed gradual decline in contrast, which are invisible to the layman.
- Cost. With excellent quality transfer images price of the device affordable for most buyers.
- High-quality color reproduction. Most led devices have a high-quality image transmission.
- High efficiency. At low power sufficient luminous flux. Mobile LED projectors can run on batteries.
- Small size and weight of the device. Such devices are often used as portable devices.
