With the growing popularity of laser TVs, more companies are entering the market, and consumer interest is also increasing. However, due to their similar appearance to projectors, many people mistakenly believe that a laser TV is just another type of projector. In reality, there are significant differences between the two in terms of technology. Today, we’ll explore the key distinctions.
Laser TV
First, let's look at the light source. Laser TVs use solid-state laser technology, while traditional projectors typically rely on ultra-high-pressure mercury lamps. The lifespan of a laser light source can exceed 20,000 hours, which translates to over 8.5 years if used for 8 hours daily. In contrast, the life of an ultra-high-pressure lamp is usually around 5,000 hours, or about 2 years under the same usage conditions. This makes laser TVs much more durable and cost-effective in the long run.
Second, installation requirements differ significantly. Projectors need a considerable amount of space to achieve a large image. For example, a 90-inch screen requires at least 3 meters of distance, a 100-inch screen needs over 3.5 meters, and a 120-inch screen may require up to 4.2 meters. Additionally, some extra space is needed for wiring. This can be challenging for small homes looking to enjoy a big-screen experience.
Laser TVs, on the other hand, use short-throw projection technology, allowing them to display a 100-inch image from just half a meter away. Some models, like those from Hisense, can even project a 100-inch screen from as close as 30 cm. This makes them ideal for small living spaces, as they can be placed directly on a TV stand alongside the screen, similar to a flat-panel TV.
Another important factor is brightness and light resistance. Laser TVs use high-brightness lasers combined with ultra-short throw lenses, which help reduce light interference. They also have better anti-glare performance compared to traditional projectors. However, they still face some challenges in bright environments.
Projectors, on the other hand, rely on diffuse reflection to avoid direct glare, which makes them less effective in well-lit rooms. To get the best viewing experience, users often need to draw curtains to darken the room.
In summary, if you're setting up a home theater, a laser TV might be the better choice due to its convenience, durability, and performance. For commercial use, both projectors and laser TVs can be considered, though laser TVs tend to be more expensive upfront. Ultimately, the choice depends on your specific needs and budget.
Wireless Router
The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.
Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
