What is camera transmission system control system auxiliary system?


2.1.4 transmission system


In the video display system, the signal to be displayed is transmitted to the signal transmission part of each display unit.


2.1.5 control system


For video signal scheduling management, including image segmentation and splicing, image display parameters (such as position, color, brightness, uniformity, contrast, etc.) setting and adjustment, video signal distribution and switching.


Auxiliary system


Supporting projects for supporting video display system, including control room, equipment room, power supply and distribution, lightning protection and grounding system, etc.


2.1.7 light emitting diodes


A semiconductor device made of semiconductor materials such as group Ⅲ - Ⅳ compounds that will emit light when applied voltage.


2.1.8 LED video display screen (panel)


Through a certain control mode, the LED device array is used to display the video screen.


2.1.9 CRT display


It is composed of an electron beam device. The electron beam emitted from the electron gun bombards the glass surface (fluorescent screen) coated with phosphor to realize electro-optic conversion and reproduce the image.


2.1.10 liquid crystal display


The applied voltage changes the orientation of liquid crystal molecules to modulate the light intensity passing through the liquid crystal to produce gray or color images.


2.1.11 plasma display panel


The plasma generated by gas discharge is used to trigger ultraviolet light to excite red, green and blue phosphors, which emit three primary colors of red, green and blue, forming a color image display screen on the glass plate.


2.1.12 digital light processor


Semiconductor digital optical micro mirror array is used as the imaging device of light valve.


2.1.13 front screen projection


A projection in which an image is projected on the viewer side of a light reflecting screen.


2.1.14 rear screen projection


The projection of images to the audience's side through the transmission screen.
