1. Buy a higher brightness model.
2. Use a high gain screen.
3. Reduce the projection size.
Buy a higher brightness model <br> This is the most fundamental and thorough approach, but according to the standard of mainstream home theater, usually within 2000 lumens. For example, Sony and JVC have published 3D models with a maximum brightness of no more than 1300 lumens. Manufacturers should make comprehensive considerations in terms of heat dissipation, mute, cost, etc., so there will be no ultra-high brightness 3D home theater machines in the near future (except Hi-end and professional machines). The ideal 3D projector, the nominal brightness is almost double that of the 2D model.
Using a High Gain Screen <br> This is the most operationally feasible to increase brightness by using a screen with a gain of more than one. In commercial theaters, some high-gain metal curtains are often used to solve the problem of reduced brightness. In the same way, the high-gain screen is also suitable for the home theater 3D projector, but there are dilemmas.
First of all, with the increase of the gain, the viewing angle of the screen will become narrower and narrower, just like the low-end TN screen liquid crystal display. The brightness of the screen is different at different angles, and the more off-center axis is more obvious, eventually leading to the deterioration of the picture quality. . Followed by hot spots. The general high-gain curtain is of the wave-bead type. The bead particles on the curtain material are rough and large, and hot spots are prone to occur. Especially in the scenes with bright and light colors, the picture will have serious grain phenomenon and completely destroy the picture. Therefore, do not blindly choose high-gain curtains. When the gain is greater than 1.3, pay more attention to the two points mentioned above. Is there any obvious difference in viewing angle and hot spot? Some high-end projection screen manufacturers will use "microbeads" technology or other screen materials to solve these problems. Everyone should pay attention to the comparison when purchasing.
Reduce the projection size <br> This trick is also very useful, but the use of the projector is for large screens, to reduce the screen size to accommodate the brightness, it is helpless. This trick is not only used on 3D models, but also works with any type of projector. Many friends who have just set up a home theater lack the concept of brightness, and often ignore the screen size which will cause the brightness to drop. A 16:9 100-inch screen area is 2.76 square meters, 150 inches is 6.21 square meters, the difference between the two areas is 2.25 times, so a reasonable control screen size is very necessary. According to the 3D model that Sony and JVC have already published, with the 1.0-gain screen, the 100-inch is the upper limit. When it is too big, it is prone to insufficient brightness, causing deterioration of image quality and accelerating eye fatigue.
