Description

Technical field:

[0001] The invention relates to an optical machine, in particular to a low-frequency reinforcing optical machine for a projection display. Background technique:

[0002] At present, when reconstructing dynamic image data, common displays are nothing more than fixed-size displays such as cathode ray tube (CRT) displays, liquid crystal displays (LCD), and projection displays. When the image data needs to be enlarged for viewing in a larger area, the cost of a display device with a fixed size often doubles rapidly with the expansion of the display size. Therefore, in the large-size display field, projection displays are still the mainstay.

[0003] However, as the size of the image frame increases, the brightness of the frame in a standard area will decrease with the enlargement of the frame size. Moreover, the luminosity of light-emitting components has its limit. If you forcefully increase the size of the bulb, change the gas pressure in the bulb, increase ...
