Ultra-thin + surface +HDR=Q2EU 16th Jingdong sells 
Among the new products released this time, Q2EU is a TV that targets ultra-thin surfaces as a selling point. HDR's high dynamic range is its outstanding feature. The product incorporates Changhong's new design concept, using a gold base, a brushed metal frame, and one-piece molding. It is also inspired by the curvature of the Eiffel Tower in France. The thickness of the fuselage is only 14mm, which is more advanced among similar products. 
Naked eye 3D TV Q2ND will be available 
Changhong X1 naked eye 3D mobile phone will be listed 
In terms of hardware design, the Changhong X1 mobile phone adopts a 6-inch design and is equipped with a 1920×1080 Full HD IPS screen.

Also very worthwhile to say is that the X1 is equipped with a 4250mAh polymer battery, continuous playback of video can reach more than 10 hours, which will give the product's core positioning - 3D video playback, bring a better experience.
Changhong launches the first naked-eye 3D TV and mobile phone layout naked-eye 3D ecology
On October 16th, Changhong introduced CHiQ's second-generation new Q2EU series of new ultra-thin surface designs and HDR high dynamic range technology. At the same time, it was released on the Jingdong Mall line. Including the 48-inch, 55-inch, 65-inch three products, priced at 5997 yuan, 7997 yuan, 12,997 yuan. At the same time, Changhong also announced that it has reached a strategic partnership with Kangde New Vision and Oriental Vision to deploy the naked eye 3D ecology. Its first naked-eye 3D TV Q2ND and the first naked-eye 3D mobile phone X1 will be on the market soon.
CHiQ's second-generation new Q2EU supports deeper technological breakthroughs in the HDR ultra-high dynamic range beyond MPEG-2, MPEG-4, H.264/H.265, and RM/RMVB video decoding. The dynamic range can reach 0.01nits-2000nits, which is more clear and natural than the traditional TV's 0.24mits-400nits screen, the contrast ratio is 2898.3:1, the black is more pure, and the overall display effect is more prominent. In terms of voice control, Q2EU still supports the Ciri voice system. Based on traditional operations such as voice switching, TV program search, search, and input, the Q2EU adds support for local dialects.

At the press conference, Changhong, Kangdexin, and Dongfang Vision have reached an in-depth cooperation in the field of naked-eye 3D, and released Changhong's first naked-eye 3D TV Q2ND that has been mass-marketed. The new glasses-free 3D product launched by Changhong will provide technical and content support from Kangde New Vision and Oriental Vision. Among them, Kangdexin is a developer of naked-eye 3D technology in China and is responsible for developing the naked-eye 3D technology with Changhong. Oriental Vision is a 3D content and application provider, and assumes Changhong's naked eye 3D product 3D content supply.
However, Changhong did not disclose too much about this product, we only know that this product will be listed before the end of the year, it is quite looking forward to.
Changhong X1 adopts the high-definition naked eye 3D technology provided by KDX, based on cylindrical lens 3D display technology, allowing users to achieve 3D content viewing with the naked eye. Compared with the traditional naked eye 3D, the Changhong X1 mobile phone supports human eye tracking. It can automatically adjust the sequence of picture interweaving according to the eyeball azimuth and expand the 3D angle. The user can watch the 3D effect in real time without having to maintain a certain posture for a long time. The software supports user-friendly settings such as 3D effect depth adjustment, 2D/3D conversion, and a better user experience.
