Drones are slowly infiltrating into mainstream thinking, and DJl's flight series includes a built-in camera and a simple-operated turbine engine. Phantom 3 Professio nal is a new product from its family, available in two versions: $1,259 for Professorsional and $999 for Advanced.
The difference between the two is that Profesional can shoot 4K video, while the latter can only achieve 1080p or full HD quality. The appearance of Phantom 3 is close to that of Phantom 1. There is a slight difference between the two, but they are all round and white.

Phantom 3 doesn't have much improvement in visual design. The fuselage is designed with a new motorized tilt to ensure better stability, while the exterior is equipped with a wider landing gear to help the camera view not blend into the aircraft itself. An additional additional compartment houses a new down sensor to support indoor flight.
The battery has also been slightly modified, and the appearance is no different from the previous one, but it is useless to put the Phantom 1/2 idle battery in Phantom 3.
However, I think Phantom 3 is actually a big chunk of cumbersome, because many users just throw it aside after buying it (probably because it can only fly for 15-20 minutes even if it is full of electricity).
And any updates need to buy extra parts, you want to update to Phantom 3, $ 149 is not cheap.
The launching device has been much smaller, adding more buttons, an LED display with built-in battery and a USB interface.
The buttons on the launch device allow you to change the angle of the camera without using the app, start/stop recording, taking photos, and a few other features, which means you don't have to be forced to connect to your phone or tablet.
TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the Liquid Crystal Display is driven by a thin film transistor integrated behind it. This can Display Screen information at high speed, high brightness, and high contrast. TFT is an active matrix liquid crystal display.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can be accurately controlled Display color gradation, so the color of TFT liquid crystal is more real.
In the fierce competition among many flat panel displays, why TFT-LCD can stand out and become the next-generation mainstream display is by no means accidental, it is the inevitable development of human technology and thinking mode. The liquid crystal has avoided the difficult light-emitting problem successively, and the light-emitting display device is decomposed into two parts by using the excellent characteristics of the liquid crystal as a light valve, namely the light source and the control of the light source. As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and life, and they are still being deepened. Since the invention of LCD, the backlight has been continuously improved, from monochrome to color, from thick to thin, from side fluorescent lamp type to flat fluorescent lamp type. The latest achievements in luminous light sources will provide new backlight sources for LCDs. With the advancement of light source technology, newer and better light sources will appear and be applied to LCDs. The rest is the control of the light source, the technology and process of the semiconductor large-scale integrated circuit are transplanted, the thin film transistor (TFT) production process has been successfully developed, the matrix addressing control of the liquid crystal light valve is realized, and the light of the liquid crystal display is solved. The cooperation of the valve and the controller enables the advantages of the liquid crystal display to be realized.
