When the Spring Festival was over, the bonus benefits that were in your hands began to stir, and the New Year did not add anything to your nest. It always felt irritating. The geeks who love to play games have already had a DIY list in their hearts. Do they love watching movies and TV shows? Many people think of a monitor, but Xiao Bian thinks that watching a video on a computer monitor lacks a sense of ceremoniality. Observing the movie itself is a spiritual pastime. The “big screen†brings not only a sense of immersion, but also a better one. The dignity and satisfaction.
The choice of "big screen" can be roughly divided into two types: screened televisions and screenless televisions. On-screen television generally refers to flat-panel televisions, and non-screen television refers to projection. What kind of "big screen" equipment is suitable for our nest? Of course, we must adjust to local conditions.
Get the largest screen smart micro-budget budget at the lowest cost: 2K-5K
Ordinary consumers are not very sensitive to "quality", but the size of the screen is indeed obvious. Think about the color, brightness, contrast, and dynamic effects of the screen when you are watching movies in the cinema? The immersive feeling brought by the oversized mask covers many details. So Xiaobian's recommendation to such small partners is to find bigger screens within the budget.
This wave is clearly projected to victory. Projection technology has been developed for many years and has long since been transformed into a civilian item. After the emergence of cheap LEDs, the life span of home projectors has also become longer. In particular, the intelligent micro-projection that has emerged in the past two years has broken the myth of projection fever with superb cost performance. Internet brands such as polar rice, nuts, and micro-whales have even lowered their smart projections to the thousand yuan price point, and have not been affected by the recent panel price hike.
Most of these smart micro-projections use LED micro-projection of DLP technology, the technology is the most mature, the effect is good and the cost is relatively low. DLP projection technology can achieve brightness of 1000-2000 lumens, relying on the color wheel and DMD chip movement, but the single-chip DLP projection slightly worse in color performance. The 3LCD projection technology is mostly used for high-end projectors, such as Epson, Sony and other brands of projection, the projection image is more clear, more accurate color. There is also LCOS projection technology, the production process is complex, the cost is very high, but the color saturation, contrast, brightness, resolution and other performance are very good, the price is also expensive.
However, the entry-level smart projection resolution and brightness are flawed, most manufacturers will evade light claims to support 4K decoding playback, but does not have 4K resolution display. It is understood that most of these projection resolutions are at the level of XGA or WXGA, and a few support Full HD. The brightness is even more expensive. The ANSI lumen value of the projection is fixed. When the projected area is larger, the average illuminance on the screen naturally becomes smaller, and it looks darker. Of course adjusting to the appropriate screen size, 500ANSI, WXGA projection is also acceptable.
Get the largest screen ultra short throw projection budget in the shortest distance: 8K-3W
Traditional projections have strict requirements on the spatial distance when they are arranged. If you want to get a bigger picture, you must have a longer distance. However, ultra-short focal projection breaks this limit.
The projection ratio of an ultra-short focal projection can be up to 0.6, which means that you can project 100 frames at a projection distance of 1.2 meters. The reflective ultra-short-focus projection can project 100 frames at a distance of 0.1-0.5 meters. In this case, the biggest advantage of this technology is to save space, especially now that the rent is so expensive. If you want to buy a normal projector and you want to shoot 100, you still have to worry about the size of the room. At the same time, the scenes in the company office, the school classroom, and so on are also of great value.
Not only is it more space-efficient, most of the ultra-short focal projectors now have a reflective design, and the light source is more laser-based. After the reflection on the screen forms a complete image, it enters the person's eye. The advantage of this is that the light that finally enters the human eye is very soft and less irritating to the eyes than the LCD TV. And the laser light source has a higher brightness and a longer life.
Of course, ultra-short-focus projection is not a panacea. The most obvious short board is the distortion of the screen. The ultra-short focus and distortion are the dead ends of the shadow. In the actual display, the middle part of the display screen is generally clear, and there are some blurs around the edges. As for the phenomenon of earlier brightness and color unevenness has been greatly improved, the current ultra-short focus technology using laser light source, has made a great breakthrough in color brightness. The physical resolution has also been greatly improved. The domestic manufacturer Hisense has launched a 4K resolution laser television.
The best picture quality + large screen Large screen TV budget: 1.5W starting "no screen" is large, but it is necessary to view the hero in terms of quality, or to have to watch "flat screen" flat-panel TV. Moreover, large-size high-resolution LCD TVs are also becoming popular. Internet brands are constantly experimenting with large-screen LCD TVs. Flat-panel TVs with a size of 75 inches or more will be increasingly sought after in the high-end market.
LCD technology has been very mature, and the brightness, sharpness, color, brightness and darkness brought by large-size high-end LCD TVs are beyond the scope of projection. In particular, HDR technology on LCD TVs brings high peak brightness, giving the picture more brightness and color detail. Like Samsung's newly released QLED TV this year, it can exhibit a peak brightness of 1500-2000nits. The Sony Z9D, which boasts the strongest light control master on the surface, has a peak brightness of 4000 nits.
Ultra-high resolution is also expected projections can not be, 4K is already very common, 8K is also gradually being used commercially, and even 10K are often seen in the major exhibitions. The details of the picture quality brought by such high definition are a great challenge to the content creation, storage and transmission. If it is non-professional demand, 8K TV is now estimated to buy just look at slides.
In addition, high color gamut and high color number color performance almost completely explode ordinary projection equipment. Samsung's Quantum Dots, Sony's Terricolor Charm, and Sharp's four-color technology all have unique skills in color display.
In addition to large-screen LCD TVs, large-screen OLED TVs are also a force that can not be ignored. Although large-screen OLEDs still belong to the “high price†category, they are definitely the best choice for local tyrants who are not bad. Because it has the closest quality to the real world.
Summary: There are three choices for screens and screens. Who is your dish? If you are an ordinary user and just want to put a decent viewing equipment at home, then a 40-inch LCD TV is enough. However, if you want to experience the effects of "shocking," you can't follow the conventional routine. Low-budget, smart projectors can satisfy your pastime; budget is sufficient but home space is limited, ultra-short focus projection is the best solution; do not care about the budget of the local tyrants, directly on the super-flat ultra-high resolution flat-panel TV. In the end, I wish you all the best to start work and get your favorite video equipment as soon as possible.
