Now projection screen on the market there are several materials that projector screen what good use of it? A friend in need then looks down.
Before you know what screens are used for the projector, let's take a look at what projection screens are available.
First, the glass fiber screen: the curtain is superior to the original United States. Divided into white glass fiber and gray glass fiber. The base fabric is woven from glass thread, and the surface layer is coated with PVC material with special projection effect. Thanks to the support of the fiberglass backing, there is no need to level and the natural stretch will be straight. Its greatest advantage is that it can remain flat even in the case of temperature differences and large climate changes. The gain and contrast are increased due to the action of the fiberglass backing. The white screen is brightly colored, and the gray screen increases the contrast. In the past, the projection equipment was bright enough, and the gray screen was used when the contrast was insufficient. At present, most high-definition projection equipments are faithful to real colors, and the new-generation HD projection equipment itself has sufficient contrast, so most people will choose white screens. Glass curtains are widely used in high-end screens. Glass fiber screen features: bright and realistic, high contrast.
Second, the woven white plastic screen: divided into white screen (also known as white plastic) and gray screen. A base fabric woven from a textile thread, the surface layer is coated with a PVC material with a special projection effect. Widely used in business and teaching.
Third, the glass bead curtain: the textile thread is woven into the cloth bottom, the surface is coated with glass beads, mainly used to increase the brightness, but the contrast, the viewing angle is not good, the picture quality is worse than other curtains. Used in bright places. Since the business education projection equipment has enough lumen light, the glass bead curtain has been used less and less, even if the teaching is generally changed to a woven white plastic screen.
What kind of screen is used for the projector depends on the environment used, and it depends on the model and size of the projector. Projectors can meet the needs of commercial presentation applications as well as home video needs. It is beneficial to know more about the relevant knowledge.
