Ditching smart TVs, smart portable projector are on the risⅡ

August 26, 2022

On the other hand, projection is jointly created by electronic technology, optical technology, and microchip manufacturing technology, but there are only a handful of manufacturers in the world that can produce projection chips. For example, 3LCD projection technology uses LCD panels as the core device.

However, unlike the LCD panels of mobile phones, mobile phones use low-temperature polysilicon panels, while lcd home projectors use high-temperature polysilicon panels. Currently, the main global manufacturer is Japan's Epson. Therefore, most of the 3LCD projectors, the panels are mostly imported from Epson.

The other is DLP technology. Its core imaging device is DMD micromirror, which is a technology that places hundreds of thousands of microscopic mirrors on a 0.3-inch substrate. It is an ultra-high-precision device. Currently, the main manufacturer of this product is TI in the United States.

There is also an LCoS display chip, which is mainly used in screenless display, laser TV, and cinema projection. The mainstream manufacturers are Sony and JVC. Fortunately, there have been breakthroughs in this field in China, such as the first domestic inorganic oriented LCoS chip independently developed by Huixinchen in 2020.

At the same time, the light source of led lcd home projector is a kind of consumable, and its life is shorter than that of smart TV. For example, using a high-pressure mercury bulb as a light source has the advantage of high brightness, which can reach more than 3000 ANSI lumens, and has a good viewing experience. But the disadvantage is that the life is short, usually 5000-7000 hours, and the heat is large at the same time.

Using LED light source is the choice for most portable projectors 1080p, which is cheap and has a lifespan of more than 20,000 hours, but the disadvantage is that the brightness is low, and it is only suitable for use at night or in low-brightness environments.

Laser light sources are usually only used in theaters, and the brightness can reach 4000 ANSI lumens. However, with the development of technology, some high-end consumer projectors have also started laser projection. The advantages are high brightness, low energy consumption, low heat generation, and long service life. But the price is the most expensive among the three, and the price is often more than 5,000.

In general, the current smart portable projector market is developing rapidly, which meets the needs of today's young people and has rich entertainment functions and portability. However, among the core components, such as 3LCD and DLP, most of them still rely on foreign imports, and the light source also needs to be further polished.
