Founded in 1953, OS is one of the leading Japanese projection screen brands, formerly known as Okumura Shokai, which was mainly engaged in the production of cinema screens, and experienced the golden age of the Japanese film industry. When the popularity of television sets and the decline of the film industry, OS reined in the precipice, turned to the research and development of small home projection screens, and extended the industry positioning to the cultural, educational, and commercial fields in the 70s. In the face of the market trend for product upgrades, OS has a keen sense of smell, and most of them can seize the turning point of the imaging industry, and leave many innovations recognized by the industry.
For example, the "automatic lock" structure used to be common to most manual screens in the industry has a drawback in use. It relies on a rotating axis to control the hovering of the curtain, which is often difficult to stay in a specific position. When the curtain rises, due to the large inertia, it bounces to the frame and produces abnormal noise, which is easy to damage the curtain surface. The "roll-on positioning" and "diffuse rewinding" structures independently developed by OS optimize this problem, the user can control the position of the curtain at will, and the curtain behaves at a uniform speed and quiet during the lifting process. Therefore, OS has gained a firm foothold in the projection screen industry with this patented technology.
In the past, the lumens of projection equipment were generally not high, and the brightness was insufficient. Looking at the present, the imaging technology continues to advance, the upper limit of the projector's lumens has broken through, and the resolution has also changed from standard definition 480P, to HD 720P, full HD 1080P, and then to the current UHD 4K ultra high definition. Pure high-gain screens are no longer the preference of consumers, and the product features of high dynamic range, rich contrast and layering, and good light resistance are more pleasing.
OS developed Pure Mat in 2000 is in line with the development trend of projectors such as high lumens and high contrast, although the gain value is 0.8, the picture is slightly darker, but the high diffusion performance is wider than the traditional white screen. Unlike conventional projection screen manufacturers, which use PVC raw materials, OS's Pure Mat uses irregularly woven fiber fabrics to effectively improve the crystal lattice generated by LCD projectorsMoiréphenomenon, the flatness of the screen is good, and the picture quality is fine. In 2014, the rewindable Pure Mat III.Cinema (WF302) for motorized screens was launched, which is the current high-level screen material for 4K images.
In terms of home theater, many UHD 4K ultra-high-definition projectors are now equipped with HDR functions, and a screen that can fully exploit the high dynamic range of projection equipment has become the pursuit of many projection players. The HDR series of screens provided by OS in the last two years can be a good choice. Among them, HF102 draws on the advantages of Pure Mat III.Cinema (WF302) curtain material, and coats the double woven curtain with an ultra-microwave bead reflective layer, which has a peak gain of 2.7, and at the same time better controls the hot spot phenomenon of the picture caused by high gain, and the details of the light and shadow transition of the picture are full.
In OS's motorized screen product line, the STP series with tension design also uses Pure Mat III.Cinema (WF302) screen material, which has high screen flatness and is suitable for 4K and 8K ultra-high resolution home theater projectors. The SEP series has the industry's first panel split design for easy screen material replacement, while the SZP series uses a special fabric to ensure the linearity of the side tension screen, and is equipped with flame retardant certificates, making it suitable for short-range projectors in schools or offices.
The manual curtain of the OS is the SMP series, which features a rewinding shock absorber for smooth and quiet curtain pulling. Consumers who value the look and feel of 4K or 8K can opt for the PA series screens, which are similar to the STP series and feature Pure Mat III screens, but with a motor design replaced with a thick, fixed frame, and an acoustic screen design that allows the audio equipment to be accommodated behind the screen, making it suitable for home theater construction. The InfoShot series is a commercial rear projection screen, which is easier to store than traditional fixed screens, and is better used for business presentations or window advertising displays.
Most OS screens start at 10,000 yuan, and the highest sales are more than 60,000 yuan. If the budget is less than 12,000 yuan, you can consider the manual or electric curtain series of SMP, SEP, SEG; With a budget of about 2 to 60,000 yuan, you can also choose the STP electric curtain series with cable tension design, or the STF and PA sound-transparent picture frame curtain series that focus on the audition experience. At present, OS has distributors in 20 provinces and cities such as Beijing, Guangdong, and Sichuan, and you can go to the official website to inquire about the relevant physical store information, while the official purchase channel has not been opened on the domestic e-commerce platform, and more screening is required when purchasing online.
