   The projector market has reached a record high in recent years. In the home entertainment scenario with display equipment as the core, home intelligent projection has become a large market segment in the field of projection at this stage. Therefore, many students have raised questions about home projectors, such as the more typical questions below:
   - "Budget 10,000 yuan, buy a 1080P projector for watching movies, what are the good choices?家用投影仪，六千以内，不需要3D，求推荐？ 家用高清投影仪有用过的吗，哪个牌子的好？”rnrn近几年，消费升级、极致的产品体验、 Big screen trends, younger consumer groups, Internet integration, and online channel volume, these factors have jointly promoted the outbreak of the home market. Driven by home projection, the stronger the "Matthew effect" in the projection market, the more obvious the "Matthew effect". Driven by the rapid Internet technology, the entire market is developing in the direction of civilianization, high -definition, and intelligence.

   can see that the shipment is growing.
   So in the following article, we have integrated and listed some problems about the family projector. From these four perspectives, present the high -quality content of the home projector for your reference:
   · Sales data
   · Household projector type
   · Popular products and models
   · Avoid pits

   The sales data of the Chinese projector market in the year is as follows:
   S source: IDC
   Xeon, Epson, BenQ, Sony, NEC ranking in the top five.
   2018 The Solid sales volume of the project market in the middle of the country occupied 4 seats in TOP10, of which XGIMI Z6 became the highest -selling product in China in 2018; while the sales of the domestic projection market, TOP10 occupied 6 seats. X6, H2, and H1S are the top three. Of course, brands such as Epnson and BenQ also have good performance.

   In in the home projection market, (1000-3000 yuan entrance price section), like XGIMI, nuts, millet, mythology, heaven cannon cannon cannon cannon guns The new Internet brands such as Ruger and Coolle have a good performance. In 2018, the number of brands in China's smart projection market exceeded 150. In the higher -end market (6000 yuan to 9000 yuan), traditional projection brands occupy an absolute advantage. In the brightness of more than 1500 lumens, the market is still occupied by senior traditional projector brands.
   epson, Benq, Sony, NEC, Panasonic, Optoma, Ricoh, Hitachi, and Sharp are the main contribution brands.
   The market share of major brands.

   In terms of price, products under 3,000 yuan are still the highest due to low prices, and the attention ratio is 40.15%. A total of 60%of the attention of projectors above 3,000 yuan.

   It picture Source: ZDC Prospective Industry Research Institute
   So in the field of home projection, users' attention is still 1,000-3000 yuan entry models, but there is a phenomenon that users are users. The price acceptance of the projector has gradually increased, and the proportion of attention of more than 3,000 yuan is rising.
   The type of home projector
   The buyers can be divided into two categories. One is traditional classic projectors represented by Epson, BenQ, Sony, etc., and the other The class is an Internet smart projector represented by XGIMI, Nuts, Xiaomi, etc.
   The traditional projection is the feeling of the old classic machine. Whether it is from the appearance or texture, it is a classic form, including the complete rear panel video interface, control, heat dissipation, and so on. The feeling of optical component products with the advantages of Japanese manufacturers' core technology as the main style. Most of the systems used by traditional projectors are closed operating systems developed by manufacturers themselves. The functions of implementation are limited and do not have the scalability of intelligent systems. However, the picture under the technical advantages of the old -fashioned manufacturer is still leading.

   Sminton projection subverts the product form of traditional projection, which is mainly reflected in the portability, youthfulness and diversity of the appearance. On the basis of traditional projectors, chips are added, equipped with intelligent operating systems, WIFI modules, and independent UI interfaces. The Android system is more common in micro -projectors in micro -projectors. In addition, smart projection also has the characteristics of affordable prices, miniaturization, and personalization. Therefore, intelligent projection reflects its advantages in appearance, operation methods, portability, and user experience.
   Whether it is traditional projection or intelligent projection, the main technologies are these three types: 3LCD, DLP, LCOS
   3LCD's core components are HTPS panels, commonly known as high -penetrating high -temperature polysilicon; its imaging principle is The light mirror emitted by the projection light bulb is divided into three colors: red, green, and blue. After the mirror reflection is reflected, the light is concentrated in the core component HTPS chip, and then the three primary color light is mixed through the middle prism to mix the three original color light for mixing Later projects are projected into different colors of images.
   DLP projection technology is the technology of Texas instruments in the United States. DMD chips are commonly known as data microscope devices. They did not produce projectors themselves, but only produced DMD chips to supplute other manufacturers. The core components of DLP are DMD and color wheels. The principle of imaging is that when the light emitted by the bulb is passed through the lens and color wheel, it is decomposed into the DMD chip by R, G, and B. After reflection, it is projected by projection lens.
   LCOS technology, it is a new type of reflected Micro LCD projection technology, the full name of LCOS: reflective LCD projector. In fact, LCOS technology can be regarded as the length of the two LCD and DLP. Improved technology, its basic principles are similar to LCD technology. The difference is that it uses a reflex architecture similar to DLP. The advantages of 3LCD and DLP are in one, but the standards have different standards and high technical thresholds.
   · 3LCD projection technology has the advantages of accurate color reduction and convenient installation. The disadvantage is that regular dust removal, low native contrast, and weakness in the effect of DLP projection technology compared with DLP projection technology.
   · DLP projection technology has excellent performance in brightness. The native contrast is high, the product is cost -effective, and it is easier to be small.
   · LCOS technology is a rising star. LCOS performs relatively balanced in all aspects. The advantages of 3LCD and DLP are one.

   On the corresponding brand, 3LCD projection technology is mainly used by Japanese manufacturers such as Epson, Sony, Panasonic; DLP projection technology is the technology of Texas instruments in the United States. They do not produce projectors themselves. Supply of other manufacturers, such as nuts, XGIMI, BenQ, Olympic Character, Lixun; and LCOS projection technology is mainly used by Sony, Canon, and JVC.

It is okay to buy Xiaomi.
   Sony VPL-HW49
   1080p, 1800 lumens

   high-price warning, if your budget reaches about 10,000, then the last projector should be suitable for you.
   Sony family projection is divided into two lines, HD (1080P) and 4K. This belongs to the Sony HD home theater projector.
   Sony Dafa is good. One of the initiator and promoters of 4K standards. For the domestic field, the projector has reached this price, and it has already enjoyed a perfect picture. Anyone who has seen the Sony screen and projection knows that it has achieved a lot of really delicate and clear and precise appearances beyond others. The exclusive core display technology SXRD (LCOS technology) image chip, the expression of resolution, brightness, and contrast is beyond the traditional ones. The picture effect, the color is realistic and delicate.
   . Fourth, avoid pits
   4k: Home projector, below 50,000, currently there is no real 4K machine (mostly rely on jitter or enhanced technology). However, there are still many manufacturers added 4K information in the publicity. The pixel requirements of 4K resolution are 8.29 million. At present, only Sony, JVC and other manufacturers can be done.
   In brightness: The most important indicator of the projector is brightness, with light sources brightness, color brightness, ANSI brightness, ISO brightness. The brightness of the light source refers to the light brightness of the bulb in the machine, which is not true. The color brightness is the "Information Display Measurement Standard" written by the ICDM of the International Show Metrology Committee. ANSI and ISO are recognized international standards for reference. ANSI is generally more accurate, and now there are false standard ANSI brightness, so be sure to pay attention to screening. ANSI does not have to watch it during the day.
   This projector requires more reference to the actual situation, look at the actual photos released by the buyer, and refer to the actual situation of different scenarios, the brightness and imaging effect of the product under different light.
   Themaked bulbs and LED machines, the mainstream brightness of the bulb machine is higher than the brightness of LED, the shortcomings of the bulb are not long, and the LED should be covered with full light during the day. Living room, you need to watch during the day, choose a bulb machine. In the bedroom, vote for less than 100 inches at night, and choose LED. LED can make small Android systems in size, long life, and built -in their respective Android systems.
   The main factor that determines the price of the projector is the size of the projection chip. The larger the chip, the higher the cost. The projection chip technology has been said before, three. DLP, LCD, LCOS.
   The type of light source: high-pressure mercury lamp (UHP), LED, LED-laser mixed, laser, lamps.
   has no eternal good and bad, only to choose suitable models according to the scene. For example: Living room party with poor shielding-high brightness DLP and 3LCD models, bedroom night movie party-portable models, home theater/independent audio-visual room-contrast and excellent LCOS model Noodle LED/Laser projector.
   At this stage, the 3D function is still as an attached function of projection. The experience is far from reaching excellent, so there is no need to deliberately pursue.
   C selection of suitable curtains. The projection display effect will be more effective. But one point, the projector is a light display device after all, and it cannot completely replace TV and large screens.
