PURPOSE: To increase remarkably an optical output of a 1st color by asymmetrically arranging slots of a 1st area of an input mask with respect to a small lens arranged in a 1st direction. CONSTITUTION: A width of horizontal slots 62 is selected to be 50% of a smaller size of a small ...
The invention relates to a projector (1) with at least one object lens (2), a carriage (3) movable approximately parallel to the optical axis of the object lens (2) from a first operative position (projection position) to a second operat... H Hartung,P Knig 被引量: 0发表: 1994年 ...
Speakers refer to the sound output; in the past, projector speakers were merely acceptable, with low volume and poor quality, leading users to external audio equipment. However, with the rise of home entertainment and individualism in the market, along with advancements in portable sound technology...
The laser projector adopts light separated from machine design, and the light source is connected to the projector by optical fiber. The hidden trouble of light bulb explosion resulted from continuous operation is eliminated forever because the laser projector doesn't contain light bulbs and the heat...
Optical pickup device, information reproduction/recording apparatus, and information processing apparatus The present invention provides an optical pickup device that is resistant to noise in a signal or an RF signal outputted from each light receiving member. Current signals outputted from the light ...
Dual lamp system for projector system with L-type optical engine Disclosed is a light source module, particularly used in a projector system, comprising a first and a second light sources generating a first and second light rays, a first and a second reflective mirrors disposed on a respective...
PROBLEM TO BE SOLVED: To provide a projector for suppressing damage to a peripheral circuit even when a signal is incorrectly input into an output terminal.;SOLUTION: An amplifying circuit Apj2 and a switch SW are connected in series between an input terminal Ipj and the output terminal Opj....
10W large audio cavity speakers with built-in DSP chip to reproduce clear treble and deep bass. Dustproof Design & Versatile Connections: The fully enclosed optical engine design effectively prevents dust from entering, ensures lo...
A projector, that projects an image, includes a light source, a liquid crystal panel that modulates light output from the light source and forms an image in response to input image data, a projection optical device that projects the image formed by the liquid crystal panel, a control device ...
yes, you can connect a sound system to a projector to enhance the audio experience. most projectors have audio output ports, such as a 3.5-millimeter (mm) headphone jack or an optical audio port, which allow you to connect external speakers, soundbars, or home theatre systems. by ...
