In recent years, laser TV has become the new favorite of home big screens. From the price of falling below 10,000 yuan to the continuous improvement of performance, manufacturers are constantly optimizing products. However, some details of the product are easily overlooked. Only when the user actually takes home and experience it for a while, will the laser TV still have these pain points to be solved.
The first thing to say is the interface design of the laser TV. Since laser TV is an ultra-short-focus product, there is almost no need for a projection distance, so the back of the laser TV will be very close to the wall.
Most of the laser TV interfaces are designed on the back of the fuselage, so users often do not see the interface position when connecting other devices.
As the main force of the home screen, there are many devices that need to be connected to the laser TV during daily use. From gaming consoles to Blu-ray players, users mostly connect them to a laser TV when they need it.
The laser TV is very close to the wall sticker, so it is more troublesome to operate. If you move the body, the size of the laser TV is relatively large, and it is very inconvenient to move it.
From the perspective of convenience, manufacturers can put commonly used interfaces such as USB and HDMI on the side of the fuselage, so that users do not have to worry about connecting other devices. The author believes that this design is more humane and can also make the user's experience better.
Thermal out of focus: the culprit of the picture
Thermal out of focus is also a problem that plagues many laser TV users. Thermal out-of-focus refers to the slight distortion of the lens due to changes in internal temperature at the beginning of the laser TV, resulting in a change in focal length. Simply speaking, it is a blurring problem caused by thermal expansion and contraction.
The best way to solve the thermal out-of-focus problem is the autofocus function, but since the laser TV uses reflective ultra-short focus technology, the image is reflected by the curved mirror.
Therefore, it is more difficult to achieve autofocus. The user also needs to manually adjust the appropriate picture, which is more troublesome.
Limited by technology, the current laser TV is not equipped with auto focus function, so the thermal out of focus problem can not be solved very well. But with the innovation of technology, I believe that the auto focus function will be applied in the field of laser TV in the near future.
Whether it's thermal out of focus or interface design, these are the details of laser TV. If you don't experience it, it's hard to find it.
However, as an emerging product, if laser TV wants to get the user's favor more quickly, every link must be perfected. Therefore, in the author's opinion, these small-scale problems must be given enough attention. (Zhongguancun Online)
Braided Wrap Around Sleeving,Braided Split Loom For Cable Harness Protection
1. Braided Wrap Around Sleeving offers innovative solutions for the protection of breakout areas
and provides easy removal when is necessary an inspection or maintenance of cables.
2. The special open structure allows to be installed after other components, for example copper terminals and connectors.
3. A strong resilience protects wires and cables and meanwhile provides exceptional abrasion and flame resistance.
PET Wrap provides the same flexibility and abrasion resistance as the PET Expandable Braided Sleeving but with the added feature of a hook and loop closure running the length of the material.
This allows you to work on segments of the cabling, rather than having to remove the entire covering and re-run all of its contents.
