Super White Face Value - The Initial Impression of Ethan D1 Smart Projection

Established in November 2013, Chengdu Extreme Technology Co., Ltd. was the first high-tech innovative company to propose the concept of “non-screen TV”.

Since the first non-screen TV was released in November 2013, ExtremeTech has spent four years. In 2015, Nomi Screen TV became the first smart micro investment product with a market share of 51.4%. In the global market, shipments of polar meters have surpassed the traditional international giant LG from the first quarter of 2015, followed by leading all the way, ranking first.

On March 23, 2016, Mimi released its 2016 flagship new product in Beijing - 3D-enabled LED light source 1080p Full HD without screen TV H1, July 25, 2017 Kemi launched the world's first 120-inch 4K dual color in Beijing on July 25, 2017 Laser non-screen TV T1, 100-inch 1080P laser screenless TV A1 Pro and A1, no screen TV Ever since the era of high-quality high-brightness ultra-high-definition, no matter whether it is resolution, brightness or picture quality, no screen TV has broken the smart projection market The limitations have enabled the company to challenge the traditional vision of TV at the beginning of the business.

At the end of 2017, Lomi's brand, Ligh Tank, quietly released a new home-use projector, the Tantal D1. The Ethanol D1 adopts a more professional 3LCD imaging technology, which has been greatly improved in terms of color purity, picture details, etc. The special WUXGA resolution (1920*1200, aspect ratio of 16:10) shows more picture content, brightness up to 1000 ANSI lumens . The Tantalum D1 uses a square pixel architecture, which greatly reduces the jagged edges of the image and makes it particularly evident in text display.

Ethanol D1 (hereinafter abbreviated as D1) is packaged in a double-layer carton. The outer layer is a heavy kraft carton and the inner layer is a color white carton package. It effectively protects the product against violent express violations. Everyone can see the deep side of the kraft box. Scratches, and one of the white carton even without injury.

The D1 mainframe and all its accessories are tightly embedded in the thick pearl-wool package. The product protection is in place.

Internal **D1 host, accessory box, remote control and instructions.

List of accessories.

The remote control is a white ABS material with a twelve-button design. The bottom is a volume control and focal length adjustment switch. It uses two AA batteries.

Product specification and warranty book.

The accessory box includes a split-type power adapter and two 7-cell batteries.

With a three-phase plug, the adapter is 19V, 7.9A.

D1 is suitable for both commercial and domestic use, and adopts 3LCD imaging technology. The size of the optical engine is relatively large, so the overall body size is much larger than the average household portable intelligent micro-projection product, and the volume of the common commercial light bulb projection is similar. The main use of PC + ABS + metal heat sink material design program, whole body white.

The top factory is covered with plastic protective film, plastic film marked on the top of the integrated key functions of the Chinese characters notes, and hard disk open the way to explain.

The rear panel is covered with a cooling grille to take into account the function of the air inlet. The interfaces are all located on the rear panel. From left to right, the 3.5mm headphone jack, SPDIF digital audio cable interface, wired network port, USB2.0, and USB3.0 interface are used. One, HDMI interface, HDMI-ARC sound return interface, Reset hole and power interface. Since the D1 does not have an integrated sound system, multiple audio output interfaces have been added to the interface to facilitate the user's need for an external audio system. The HDMI-ARC sound return interface can be used to connect amplifiers that support this feature, while the 3.5mm headphone jack and SPDIF digital audio interface also add more possibilities for the sound system connection of the D1.

The two sides of D1 and the front and the back of each side are covered with a symmetrical dense full metal mesh cooling panel. The inner air duct is complete, the left side is the air inlet, the right side is the air outlet, and the left and the rear are The air outlet and the outlet on the right form a three-dimensional complete air duct. The dense metal grid structure panel can play a beautiful dust-proof and auxiliary cooling effect.

The front panel is covered with decorative dot pits, and the double ring shape structure in the middle hollow is a hidden electric projection lens. After the power is turned on, the remote controller power button is pressed, and the lens cap is slowly removed from the left side to the right side.

Concealed electric high transmittance coating lens.

The four wooden feet of the bottom four corners are exquisite workmanship, but the support is firm, but it does not have adjustability. For a special projection environment, when it is necessary to separately raise or lower the lens needs, the projection angle can only be adjusted by means of other items. There is a fixing screw hole in the inner side of the stepped foot, which can be used for lifting installation of the product.

The front side nameplate shows the product model, delivery information, and electrical specifications. In front of the central two rows of cooling holes for the optical focus knob, the user can adjust the 1.2-fold optical zoom without changing the distance to achieve the purpose of changing the screen size.

The buttons on the top are lined up in a row. The icon is a tiny white grooved intaglio. After the protective film is removed, there is no function Chinese comment. This is estimated to keep the overall design of the product coordinated and beautiful, but because the icons and panels The same background color, it is difficult to identify in the dark environment, it is recommended to increase the fluorescence color, easy to identify easily in the dark environment.

Push the top cover in the direction of the annotation marked on the plastic film to open the hard disk drive. Users can choose to add a 2.5-inch solid state drive as required.

Ethanol D1 packaging heart, the protection of the product is in place. D1 stunning modeling, exquisite workmanship, complete interface, with three optional audio interface, you can easily connect a variety of external audio devices. With perfect cooling air duct design, the work of wood stepping is quite good, increasing the taste and forcing the product. Built-in 2.5-inch hard disk drive, users can choose to install solid-state hard drive expansion. The front hidden electric lens cap has a full sense of science and technology, and the crowning touch accomplishes the high face value of D1.

In order to obtain better picture quality, the D1 uses three LCD imaging technologies. The volume of the optical engine is much larger than that of the DLP, and the product is targeted for both commercial and home use. Therefore, the D1 is larger and has a traditional bulb commercial projection. The size of the instrument is similar to how much it affects the portability of the product. The keys of the product are lined up on the top surface and are designed in the same color. There are no eye-catching Chinese character annotations. It is not easy to identify in a dark environment. It is recommended to increase the fluorescent color design to solve this problem.

The end of the product's appearance was introduced. The follow-up detailed evaluations were successively on-line and we welcome continuous attention.
