Home projection has become more and more popular, and projection paint is used more and more. Projection paint is popular among consumers because of its high brightness, full color and no size limitation. Nowadays, people prefer to use projection paint to make home theaters. For projection paint, many people do not know what the effect is. Today, we will make an analysis and evaluation of the effect of Langshi projection paint.
Langshi projection paint is a high-performance screen projection paint, which is made of high reflective acrylic polymer nano materials. The utility model has the characteristics of high brightness and full color when used. The performance of projection paint is evaluated from the aspects of brightness, clarity, contrast, color restoration and environmental protection performance of the projection picture.
Brightness coefficient of projection paint (also called gain)
Under the same conditions, project the same light to the vertical direction of the screen, and measure the brightness of the center point and each point on the same arc. The ratio of this brightness to the brightness of full diffuse scattering is called the screen gain. Gain is a digital representation of the inherent reflection characteristics of the screen (brightness of each angle). Normally, the higher the gain, the smaller the viewing angle.

Langshi projection paint is made of advanced acrylic polymer nano materials, containing small metal particles with good reflective performance. According to the report given by the Quality Supervision and Testing Center for Film Machinery and Audio visual Education Equipment in the Machinery Industry, the comprehensive brightness coefficient (gain) of Langshi projection paint is 2.026. It means that the projection brightness has reached the effect of S-level projection screen.

(Luminance factor β It refers to the ratio of the screen reflection brightness and the ideal full reflection surface reflection brightness at a viewing angle of 5 degrees under the same conditions)
Clarity of projection paint
Screen resolution (sharpness), commonly known as sharpness, refers to the ability to distinguish the details of the original object. The resolving power is usually expressed by the measured value of the resolving power of an optical photography system or element to two adjacent entities (usually lines), such as logarithms per millimeter line (lp/mm). The screen resolution of Langshi projection paint is 100 line pairs/mm, the screen standard for film projection is no less than 80 line pairs/mm, and the screen for video education projection is no less than 63 line pairs/mm. Therefore, Langshi projection paint can completely meet the needs of film screens and audio-visual education screens. Moreover, the clarity of Langshi projection paint is very high, meeting the standard of large screen HD projection.

Reduction degree of projection paint
The color of reflected light of projection paint determines whether the reduction degree of projection paint is good or not. The screen surface shall have good color reproduction performance, that is, the color chromaticity of reflected light and incident light shall be consistent. The color difference between the incident light and the reflected light of the screen shall not be greater than 200K. That is to say, the smaller the color value of reflected light is, the better the color reversibility of projection paint is. The reflected light color of Langshi projection paint is 17K, and the color restoration performance is much better than the projection screen.

Contrast of projection paint
Projection contrast refers to the ratio of black to white, that is, the gradient from black to white. The larger the ratio is, the more gradient layers from black to white will be, and the richer the color expression will be. Contrast plays a key role in visual effects. Generally speaking, the greater the contrast, the clearer and more eye-catching the image, and the more bright and colorful the color. The contrast of projection mainly depends on the projector, and the screen only plays a certain auxiliary role. Reflective materials such as silver powder on the surface of Langshi projection paint will form diffuse reflection to increase the contrast of projection paint.

Environmental performance of projection paint
Langshi projection paint belongs to coating products, and of course, it should also pass the national quarantine inspection. Generally, coatings mainly detect VOC (volatile organic compounds), formaldehyde, heavy metals and other contents. It can be seen from Langshi's test report that the content of VOC, formaldehyde and heavy metals in Langshi projection paint is very low. (Domestic environmental protection standard VOC ≤ 250mg/kg) Langshi projection paint also fully conforms to the strict national environmental protection standard.
