It isn't easy to find that the definition of the advertising projector of different brands is different under the same projection environment. The imaging part uses convex lens imaging technology because it is not an ideal point light source. Chromatic aberration and aberration problems will occur after being refracted by the convex lens, and the imaging will become insufficiently clear.
The reasons for the inconsistency of the clarity of advertising projector of different brands are the following.
1. The advertising projector of different brands use different parts and components, resulting in inconsistent projection clarity. The main source of imaging of the projector is the projection lamp because the light source projects the pattern onto the external opaque medium through the lamp that the lighting performance of the material of the lamp is very important. The better the material, the better the lighting performance and the clearer the imaging.
2. Different brands of advertising projectors have different definitions of power because the power of the advertising projector is a very important factor affecting the clarity of advertising projectors. The difference in power of advertising projectors of different brands will cause the clarity of advertising projectors of different brands to be inconsistent.
3. There is not much difference in the definition of advertising projector of different brands. And the high-power of a projector of the different brands in the definition is larger!
