Electronics Visual Display
An electronic visual display, informally a screen, is a display device for presentation of images, text,
or video transmitted electronically, without producing a permanent record. Electronic visual displays
include television sets, computer monitors, and digital signage. Wikipedia

Types of Electronic Visual Displays (ThinkComputers © 2020.)

As of today, the most common types of electronic visual displays include LCD, LED, and OLED
screens. Each provides spectacular displays that turn smoother and more high definition every
year. But how exactly did these pieces of technology come about? To find out, let us go and learn
about the earlier forms of electronic visual displays before we get into the technology behind the
high definition screens we know today.

1. Cathode Ray Tube
The cathode-ray tube is a thick tube made out of glass. Its one end is flattened and contains
phosphor coating inside. It produces images with a beam of electrons triggered by a hot metal
filament that causes the phosphors at the flat end of the tube to glow.

2. Plasma
Another type of electronic visual display that predates today’s screens is the Plasma display. It
works by using a grid of tiny gas capsules that make up a screen. When triggered with electricity,
the gas inside the capsules starts to glow just like an old-fashioned neon sign.

3. Liquid Crystal Displays

The entire display is made of liquid crystals that can either block or transmit light. The light
source, called the backlight, is placed behind the liquid crystals. When light is transmitted through
the liquid crystals, thousands of colored dots start to appear in the form of an image or video. In
simpler terms, the backlight is being filtered by the LCD panel to make images or videos appear on
the screen.

4. Fluorescent LCD
Fluorescent LCDs work the same way as liquid crystal displays do. The only difference is that the
backlight is composed of a fluorescent lamp. What’s great about this technological innovation is
that it made LCD screens lighter and thinner. Fluorescent backlights are also less expensive and
much brighter. However, it does have its fair share of cons. You see, this type of LCD screen uses
mercury.

5. LED Displays

The LED backlight is a new technology for LCD displays. This is probably the newest innovation
for the LCD screen since the fluorescent backlight. LED backlights use light-emitting diodes that are
able to produce bright white light without the use of any mercury. As of today, LED displays are
often used as outdoor digital signage for commercial settings.

6. OLED Displays

As of today, OLED displays are the latest innovation to electronic visual displays since LED
screens. Though the OLED display works similar to LCD displays, it doesn’t require the use of a
backlight. Instead, it’s able to produce its own light. Because of this, OLED screens can be
designed to be thinner than LCD screens. Moreover, since backlights consume lots of energy, its
absence in OLED displays make OLED screens improve battery life in certain devices.

Portable media player

A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics
device capable of storing and playing digital media such as audio, images, and video files. The data
is typically stored on a CD, DVD, BD, flash memory, microdrive, or hard drive. Most portable media
players are equipped with a 3.5 mm headphone jack, which users can plug headphones into, or
connect to a boombox or hifi system. In contrast, analogue portable audio players play music from
non-digital media that use analogue signal storage, such as cassette tapes or vinyl records.

Webcam

A webcam is a video camera that feeds or streams an image or video in real time to or through a
computer to a computer network, such as the Internet. Webcams are typically small cameras that
sit on a desk, attach to a user's monitor, or are built into the hardware. Webcams can be used
during a video chat session involving two or more people, with conversations that include live audio
and video. For example, Apple's iSight camera, which is built into Apple laptops, iMacs and a
number of iPhones, can be used for video chat sessions, using the iChat instant messaging
program.

1.2 Audio/Video System Connection

Source: © 2012 - 2020 Production Consulting Group.

Understanding the flow of signals within your home theatre starts with becoming familiar with the

three distinct types of devices that your home entertainment components fall into: Source Devices,
Hub Devices & Sink Devices

1. Source Devices are easy to identify as they generally only have AV Outputs - they play your
media and send the audio and video signals OUT.

2. Hub Devices can be trickier, as they accept both Inputs and Outputs - they do all the
sorting to organise multiple home theatre components.

3. Sink Devices are the final destination for your video and/or audio, and have mostly Inputs -
they display the video and play the sound that they receive IN. 'Sink device' is an industry
term, so we tend to say destination device for clarity.

A Typical Home Theatre

Source: Copyright © 2006-2020 Cable Chick

Let's look at a simple home theatre setup that comprises a couple of Source devices - a Games
Console and a Blu-ray Player - along with a Television and a Surround Sound speaker system
controlled by an AV Receiver.

In this example, the Console and Blu-ray player are source devices. They have Outputs which are
sending HDMI data (audio and video) out. The AV Receiver has Inputs which can accept both of
these signals in - you select which one is active with your remote control - which it then sorts and
sends on through its Outputs. Because it has both inputs and outputs, it's what we consider a hub
device. Finally, the Television receives video data with its Input, and the Speakers receive decoded
analogue audio signals, making them sink or destination devices.
This simplified diagram does not take into consideration the non-audio/video abilities of some
components. A games console may have input sockets for controllers or cartridges, but they're
outside of the scope of this guide. We're just dealing with audio and video (AV).

Keeping your home theatre linear like this can make life easier, but this isn't always possible when
new technologies emerge that aren't compatible with all of your equipment. Bypassing your AV
Receiver is covered in a different blog,
Source: Copyright © 2006-2020 Cable Chick

The Rule-Breakers

Home Theatre wiring becomes more complex when source and destination devices have features
that contradict their traditional roles. For example:

 HDMI Audio Return Channel (ARC) - found on modern TVs and Projectors (see next
section)

 SPDIF Audio Outputs - found on many TVs
 Headphone Jacks - on TVs and Projectors
 Display Port and Thunderbolt Video Daisy-Chaining - on modern Macs and PC Monitors
Features like these can allow some components to work like Hubs under certain circumstances.
Let's look at an example where a TV is being used as a hub device rather than as a destination
device.

Source: Copyright © 2006-2020 Cable Chick
Here, we're using the SPDIF Digital Audio output on the TV to send sound data to a receiver, which
decodes it for the speaker system. SPDIF can be either Optical (TOSLINK) or Coaxial (RCA),
depending on the make and model of TV. Other devices also have SPDIF support, including games
consoles and some projectors.
The main benefit of this method is that everything shown on the TV plays audio through the
speaker system, including free-to-air TV if connected. This solution is also good when your AV
Receiver isn't HDMI-ready. One drawback is that you're mostly limited to 5.1 audio, as SPFID only
works with PCM Stereo, Dolby Digital and DTS Surround Sound - it can't carry lossless surround or
7.1 formats.

TVs and Projectors which have Headphone Jacks or 2-RCA analogue stereo outputs can also be
used in the manner shown above, but you can only get regular stereo audio this way.

HDMI Audio Return Channel (ARC)
The HDMI Audio Return Channel feature is an optional ability in HDMI v1.4 (and above) hardware
that allows selected inputs to send audio data back from a destination device like a Projector or a
Television to a compatible hub device. This effectively makes an HDMI input also an output - but
only for audio!

Source: Copyright © 2006-2020 Cable Chick
This example shows free-to-air television stations being received via a rooftop antenna plugged
directly into a TV with a built-in digital tuner. In order to get audio back to the AV Receiver to make
use of the home theatre speakers, HDMI ARC is leveraged to eliminate an additional audio cable.
You aren't limited to just TV stations for ARC, either. If the Console and Blu-Ray player above were
connected to the TV as well, their audio would also return to the AV Receiver. HDMI ARC can
handle Dolby TrueHD and DTS-HD Master Audio up to 7.1 Channels, so it has many advantages.
Not all HDMI sockets have ARC enabled, though! Look on the back of your TV, or in your user
manual, to find the HDMI inputs specifically labelled as ARC. Both the TV and AV Receiver (as in
the above example) have to support ARC for it to function.

Switch / Splitter / Matrix
Switches, Splitters and True Matrixes are all considered hub devices as they accept one or more
inputs, sort the signals, and direct them to one or more outputs.
A Complex Home Theatre
At Cable Chick, we are frequently contacted by audiophiles both amateur and professional who are

working with many specialised devices at once - often mixing old and new components that don't
share common Input/Output formats.
The following diagram shows what a complex home theatre system may look like.

Source: Copyright © 2006-2020 Cable Chick
Wow! Now we can really see how the information is flowing. Here, we have a home theatre with a
TV and Projector set up to show video from any one of three sources (one at a time); a Laptop, a
Games Console and a Blu-ray player. For this to work, both the TV and the Projector need at least
two HDMI inputs, and the TV needs an SPDIF audio output. The 5.1 speaker system (run from the
AV Receiver in the middle) can play audio from any of the three source devices, plus sound from
free-to-air TV broadcasts and a Vinyl Record Turntable. A Splitter and a Switch are included to
direct the HDMI signals to both display devices.
In this instance, the projector would not be able to show any TV stations, unless it had a built-in
tuner and was also connected to the rooftop antenna. All other sources are available on both
screens after a quick fiddle with the relevant remote controls!

Cameras are an essential component of any CCTV system. Matching the right CCTV camera to a
particular application is increasingly complex due to rapid technological developments and a
greater range of applications. A system’s performance is affected by many factors beyond those
listed in the vendor data sheets. Effective camera selection requires detailed knowledge of the
camera, application, supporting architecture, and host environment. CCTV Technology Handbook
10 All CCTV cameras include three basic elements:

• Image sensor–Converts light (photons) into electronic signals;

• Lens–Gathers light reflected from a subject and focuses the light on the image sensor; and

• Image processing circuitry–Organizes, optimizes, and transmits video signals.
