There is a kind of projection that is not produced by ourselves

Miniature projection history is a high-tech product integrating optical, mechanical, and electrical technologies. The composition of sophisticated optical components is also complex, such as the flaws in the design of optical circuits, or the quality of components in the optical path, and they are directly reflected to the projection effect. However, during the use of projection, most people do not understand its working principle, internal structure, and the origin of optical components. This also creates a disorderly image of the optical components in the projection market. .

The basic working mechanism of the projector display system is to use a high-brightness light source to illuminate the display chip and enlarge it through the projection optical system to project the image of the chip onto a large screen of 10 feet to several hundred inches.

About the projector internal structure

Then, from the working principle of a simple projector, it is not difficult to find that the core components involved in a projector can be divided into three systems: an optical system, a cooling system, and a circuit system. Among them, the optical system is the core, also known as "optotype machine" or "optical engine", and the expert way "to buy a projector is to buy a light machine" because it directly determines the picture quality that the projector can achieve. Projector manufacturers integrate the imaging chip, light source, lens path, and heat sink into one mechanism to create an integral component. This mechanism component is called a light engine or an optical engine.

When we were young, we always asked my mother, where did we come from? For today, as a projecting white, do you think naively that these optical core components are produced by the brand owners themselves? In addition to the light engine, the core components of the projector also include heat sinks, circuit boards, and molds (cases). Most projector brands have not even gone through the internal device development and production, but have purchased optical elements such as projectors. The device then assembles the loose parts to open the mold shell, and only a small part of the enterprise is produced by the whole machine.

Most of the well-known projection brand manufacturers are DIY assembly?

In the age of technology explosion, it is the era of derailment of R&D and sales. The following are the large projection-related production R&D companies in China. Most of the projected optical components are from these manufacturers. For example, Foshan Pulihua has become the ninth business group, and it is still only the R&D and production of projection optoelectronic products; Yangming Optics may be involved in a wide range of applications, including liquid crystal displays and projectors, but all of them are also optical components; Zhongda Dentsu mainly produces power supply and heat-dissipation component production R&D; Epson technology mainly produces IJP, LP, LFP, projector products, Print Header, Scanner, circuit board, related products (plastic products and metal parts), etc. The company's main products include color television sets, high resolution monitors, color picture tubes, high resolution display tubes and related key parts.

It's hard to imagine that internal components such as light engines, motherboards, molds, and heat sinks will eventually come together and go through ups and downs! Buy components and parts from manufacturers, and then make electronic solutions. ID company designs the appearance, finds the mold factory to open the mold, finally finds a cottage small workshop assembly, so under the perfect package conceals the support without the patented technology, does not guarantee the assembly, does not guarantee the component production, when the projection machine is bold When the market goes to the market, brand owners still boast that they are leaders in R&D. Unfortunately, in fact, from research and development to production, they are not able to touch the edge. In the assembly process, people cannot help but suspect that they have turned their backs. It's possible that this kind of unreliable production chain will have to make a big question mark for the effect of the final projection.

Actually, such phenomenon has been a problem in the projection ecosystem. For example, the so-called brands in the industry are all using the 0.45” WXGA128×800 resolution public template light engine from the same light machine factory. Micro-projection products use light machines from Shenzhen and Taiwan, and currently the main micro-projection and intelligent projection light machines in the global field mainly come from: Kingview Technology, Hongdie Technology, Anwar Optoelectronics, and Yangming Optics.

Rise: Divine Painting of the Complete Industry Chain of Projection Industry

The strength of scientific and technological innovation is a measure of how much R&D and production of new products are made by companies and the level of satisfaction of market consumer groups with respect to products. This is where many projection brand manufacturers are weak, and it is precisely the lack of technology manufacturers that control the brand market. Common problems.

As the originator of the smart projection technology, the Legend created a legendary X1 smart cinema selling independently, followed by the constant upgrade of the Y1 and Z1 paintings. It not only uses the industry’s leading autofocus technology, The core patented technologies such as image touch technology have laid the foundation for the fifth generation of smart times. At the same time, it is also the hope of the rise of the projection industry.

Shenhua Technology (Shenzhen) Co., Ltd. is a wholly-owned subsidiary of Hong Die Technology (Shenzhen) Co., Ltd., a global leader in optical coating and optical lens processing. It is the only company in the world that integrates projection light source development, optical lens processing, optical path design, and optical system. The vertical industrial chain of production and intelligent projection machine production integrates high-tech enterprises. Shenhua Technology is mainly engaged in the research and development of optical projection products such as intelligent projection, optical engines, and micro projectors. It has successfully developed full-line digital intelligent projectors such as LCD series, DLP series and 1080P series with completely independent intellectual property rights.

Shenhua Technology has the advantage of being incomparable to other traditional projection companies in smart projection and miniature projection. It is the world's first manufacturer of miniature projectors, and has independent intellectual property intellectual projection technology. In 2011, Shenhua Technology developed the world's first truly intelligent projection, integrating Android system, virtual touch interactive operation technology, gravity sensing and intelligent autofocus technology, to create a precedent for home smart projection.
