Projection technology more and more mature today, a wide range of projectors has entered everyone's life, and now many young people enjoy the high-tech, it is also still suitors comfort, bedroom lying in bed watching the films, and if When decorating the room without taking into consideration the space reserved for the projector, or the situation where the front projection of the ceiling cannot be carried out, the projector needs to be placed on the bedside table for side projection.
Now many smart projectors, such as Dangbei projector F1 supports trapezoidal correction, so side projection is not a problem. However, when some friends use the side projection, they will find a faint "flare" outside the screen, which affects the viewing effect. So what is going on?
In fact, this is caused by the basic principle of the projector: optical zoom makes the bright surface projected by the optical machine will not change with the change of the trapezoidal correction. The trapezoidal correction only corrects the projected picture, and the whole projection of the optical machine The bright side of it still appears around the screen in conversation, especially the higher the brightness, the more obvious it is.
It can be seen that these projectors have different degrees of external light spots when they are side-projected. The picture shows the screen in highlight mode. If you adjust to the standard mode or the economic mode, it is difficult to see these spots.
So is there any way to eliminate these spots? In terms of mechanism, the appearance of light spots on the side projection cannot be eliminated, and only the front projection can make the "non-appearance" of the spot, so if conditions permit, it is recommended to use the front projection. Or in the living room with part of the light, the light spot will not be obvious because of the low brightness.
In summary, the side projection can indeed be watched through keystone correction, but after all, some picture loss will occur, and the picture effect will not be optimal. However, the front projection or the side installation on the wall can avoid the appearance of light spots and make the projection effect better.
