Problems solved by technology

At this time, the air pressure inside the bulb is much higher than the atmospheric pressure. Not only must the mechanical strength of the bulb’s glass bulb be increased, which will increase the manufacturing cost, but also increase the risk of explosion, which is by no means an ideal choice.

Embodiment Construction

[0068] The aforementioned and other technical contents, features and functional effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments given in conjunction with the accompanying drawings.

[0069] The low-frequency reinforcing light machine for projection displays of the present invention can be implemented smoothly no matter it is applied to, for example, LCOS projection displays or DLP projection displays. These projection displays all have a spatial modulation module with a plurality of cells, and the spatial modulation module will be driven according to a received image data signal to modulate the light beam from the light source, so that the projected light beams at the positions of each cell The light intensity corresponds to the above image data signal.

[0070] The present invention is directed to a projection display whose luminous frequency of a bulb includes an ultraviolet light component and a p...

Abstract

This invention relates to projection display low frequency compensation machine, wherein, the display comprises one light frequency composed of ultraviolet light ad multiple visible light bulb with brightness lower than ideal brightness; the projector is to modulate bulb beam according to one image data; the light machine comprises following parts: one reflection lens to reflect bulb beam; one even split device to receive reflection beam to divide frequency; the optical part is set with one component to absorb ultraviolet component.

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 ...
