LED backlighting is the most commonly used backlight for small, LCD panels. Light-emitting diodes, or LEDs, are practical components for a light source because of their small size. LED backlighting is popular due to its overall low cost, long life, variety of colors and high brightness.

LED backlights are housed in a light box that has a diffuser to evenly distribute the LED light. The light box is then mounted behind the LCD’s viewing area. The LED backlight comes in two configurations: array and edge lit. The array configuration has the LEDs mounted in a uniform, grid layout within the light box. This configuration gives off a very bright, even light. The disadvantage of an array configuration is that it requires a thick light box design to accommodate the number of LEDs required. The high number of LEDs in this configuration also means it consumes more power.

The other configuration for LED backlights is edge lit. An edge lit configuration is the most commonly used construction for LED backlights. This configuration mounts the LEDs along one edge of the light box. The layout results in a thin design. Edge lit also uses less LEDs overall and therefore consumes less power than an array configuration.

Another type of backlight options is the use of fiber optic technology. Fiber optic backlights use sheets of fiber optic woven cloth and are bundled by a ferrule (metal cap) to an LED or halogen light source. Advantages for the fiber optic technology includes low voltage, low power, and a very uniform brightness. This type of backlighting is ideal for custom display shapes or sizes however it is priced at a higher cost compared to other technologies available.

A third type of backlight option available uses an electroluminescent (EL) panel. The EL backlight is constructed of a series of different material layers that work together to create the light. The EL panel generates light when an electric current (AC power) is applied to its conductive surfaces. The advantage with EL backlighting is its low power consumption, no heat emission, and overall thin composition. EL backlighting is limiting in that it requires an invertor to generate the VAC needed to emit the light.

The last common backlight option available are cold cathode fluorescent lamps (CCFLs). CCFL backlights are a cost effective option typically found in graphic displays. The CCFL backlight for LCDs is usually configured with the lamp on the edge of a diffuser to distribute the light. An inverter is required to supply the voltage required by the fluorescent lamp. CCFLs offer a bright white light with low power consumption. This backlight option is not ideal for cold-temperature applications (less than 15°C) as the light output decreases with decreased ambient temperature.

There are many different backlight options available for your LCD. The most common types are LED, fiber optic, EL, and CCFL backlights. Cost and application of your product will have the highest influences on which backlight technology is best for your LCD.

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

As  a specialist in transparent Displays we are often asked whether T-LCDs can be used in ambient light, i.e. without a backlit showcase box which it does as you can see in the video attached.  But clearly the image quality is not as crisp and bright without a backlight directly behind the display.  For some clients this made it difficult to make a decision on the way forward so we made this specific video so you and any other viewers can see just how good it is in standard normal ambient light!

This just shows the quality of the transparent screen with direct sunlight rather than LED backlighting, still looking great but obviously offering a lower % of transparency than LED backlights would give. This is why we always encourage LED lighting when customers ask for our advice on lighting and how transparent displays work without lighting and in shop windows. Below is an example of how the panels look but obviously it is not sunny all year long in the UK, as in many other countries, unfortunately.

On home appliances, it is often necessary to display numbers and words to convey information, such as the current time displayed on the clock, the current temperature information on the kettle… etc. The two most commonly used displays are LED displays and LCD displays, this article will compare the advantages and disadvantages of LED displays and LCD displays, and provide a two-step quick way to quickly determine whether this product is an LCD or LED display.

LCD displays are the most common displays in daily life, from your mobile phone screen to home appliances, you can use LCD displays, but whether it is a color or black and white LCD display, in fact, the principle is the same. There are two main components within the LCD display:Backlight module

Black-and-white LCD displays are widely used in a variety of low-cost products, and the picture above is a black-and-white LCD display used in science calculator.

Advantages of monochrome LCD displays:Can show very compact information.Each display point of the calculator as shown below is very close to each other, and high-resolution text can be displayed

Power savingBlack and white LCD displays can operated without a lot of power compared to full-color LCD, when products that do not require full-color demand and need to control power consumption are often used.

CheapIf you just want to display a set of numbers or a few ICONs, the price of using a black-and-white LCD display is much cheaper than that of a full-color LCD, and it is often used in a large number of consumer products.

Disadvantages of monochrome LCD displays:Small viewing angle, not easy to use for outdoor application.Usually black and white liquid crystal display in the front view, the display is the clearest, but due to the LCD panel characteristics, as long as the side view, the clarity will be declined, outdoor will be affected by strong light, the viewing angle is not large, the clarity is not enough, LED display due to the word luminescence characteristics, there is no viewing angle problem.

Can only be used in monochromeIf you need multi-color applications, you can only upgrade to a full-color LCD display that is many times more expensive, and the LED display can simply add different colors to the LED display without significantly increasing the cost

The structure and basic introduction of the display in this article this article, compared with LCD displays, self-illumination characteristics, so that LED displays in the outdoor visibility is high, high brightness, but also no viewing angle problem. LED displays are the same as black and white LCD liquid crystals, and the display information must be designed in advance and cannot be arbitrarily transformed. The price of LED displays is between full-color LCDs and monochrome LCDs, and if properly designed, they can save the cost of achieving display performance.

This article briefly introduces the basic principles and advantages and disadvantages of two common LCD displays, and provides two steps to quickly determine whether the display in hand is an LED display, and product designers can follow these two steps to understand which display the product is used when observing the product.
