Ⅵ Frequently Asked Questions about Backlit Keyboard

Introduction

The term "backlit keyboard" refers to a keyboard that has a light beneath the keys. In low-light situations, the backlight illuminates the letters and symbols on the keys to make them visible. Because the print on the keys is semi-transparent, the light will pass through it like a window. Read this article to learn how to choose a backlit keyboard quickly.

Ⅰ What is the Backlit Keyboard?

backlit keyboard, also known as an illuminated keyboard or a backlit gaming keyboard, is one that has lights inside it. The lights illuminate the area behind and around the keys, making them visible in low-light or dark settings. For energy efficiency and increased brightness, the light source is typically made up of mini LED light bulbs. Backlit gaming keyboards are popular among computer gamers, but they can also be used for general computing tasks. G.SKILL 's multicolor backlit gaming keyboard is shown below.

 1.1 Advantages of the Backlit Keyboard

  • The distinction between a backlit keyboard and a regular keyboard is that the backlit keyboards can be used in the dark because they are illuminated from behind the keys.
  • The characters associated with each key on regular boards are simply printed on and do not light up. Backlit keyboards  are therefore the most versatile option.
  • You may have one or more colors depending on the keyboard supplier and model.A colorful backlit keyboard is a way to go for the gamer or the person who wants to add a little flair to their computer hardware setup.

While these keyboards do have a more youthful feel to them, they are suitable for anyone who is young at heart.

In general, the F and J keys have raised lines on them if you look at your keyboard (you may have to feel your keyboard).

It's supposed to help you navigate the board even when the lighting isn't ideal.

To work properly, you must, of course, know how to type efficiently and not just with your pointer finger (aka index finger).

Some argue that efficient backlighting is the answer.

Laptops with lights can be both functional and attractive.

Figure 1 Backlit keyboard

They cost more than other types of keyboards. Most models with key lighting start around $800 and rise from there - sometimes dramatically.

Illuminated keyboards use more energy than standard keyboards. It can drain your battery faster if it is not plugged in and charging.

Ⅱ How to Enable a Backlit Keyboard

Touching the keys or across the edge of the keyboard usually activates the backlit feature. When the keys or keyboard edges are not touched, the lights automatically turn off after a short period of time. Turning off the lights automatically helps to conserve battery energy, extending battery performance between charges.

Backlit keyboards for laptops and desktop computers may also include special keys or FN keys for permanently turning the backlight on and off, as well as the ability to change the color. The special or FN key to press on a keyboard varies depending on the manufacturer of the keyboard or laptop.

In the Windows Mobility Center, most new PC laptops allow you to change the backlighting on the keyboard. On Dell laptops, this is frequently Fn+F10 or simply F10. Fn+Spacebar is the hidden key for adjusting the backlit keyboard  on Lenovo laptops.

3.1 How Does a Force Sensing Resistor (FSR) Work?

In recent years, printed, thin, and flexible sensors have created quite a stir in the design engineering community. This is largely due to the proliferation of smart, lightweight, and energy-efficient technologies that have become ingrained in our daily lives. Naturally, when designing these small but powerful devices and products, the embedded components that make them game-changers should share the same characteristics.

Force sensing resistors (also known as printed force sensors or force-sensitive resistors) are a large and expanding class of embedded components, with many new sensor types introduced in recent years. Force sensing resistors    , on the other hand, are not a new technology. For decades, force-sensing resistors have been used as an embedded component.

3.2 How do Force Sensing Resistors Measure Force?

Most engineers know that the formula for force is an object's mass multiplied by its acceleration (or, F=M*A) or applied pressure multiplied by contact zone (F=P*Area). Newtons (N), pound-force (lbf), and other engineering units are used to represent "F" in these equations.

Figure 2: When a force sensing resistor is applied, the conductance response as a function of force is linear.

Pressure sensor resistors are not pre-calibrated to correlate a force reading to a known technology unit on their own. The force measurement result captured by a force sensing resistor. On the other hand, can be correlated to the applied force via a calibration procedure.

Piezoresistive sensing technology is a force-sensing resistor, This means that they are passive elements that serve as variable resistors in an electrical circuit. As illustrated in Figure 1, when the sensor is unloaded, it has a high resistance (on the order of Megaohms (M)) that decreases as force is applied (usually on the order of Kiloohms (K)). When the inverse of resistance (conductance) is considered, the thermal conduction response as a function of force is linear within the sensor's specified force range.

3.3 How do You Calibrate a Force Sensing Resistor?

Force sensing resistors  can really be calibrated with as few as two-to-three known loads due to their resistance/conductance linear relationship.

Furthermore, if the circuit is built with adjustable components, the sensor's sensitivity can indeed be adjusted for optimal performance in the specific force range.

3.4 How are Force Sensing Resistors Made?

A semi-conductive material – or semi-conductive ink – is sandwiched between two thin substrates to form force-sensing resistors. As illustrated in Figure 3, there are two types of force sensing resistor technologies: Shunt Mode and Thru Mode.

Figure 3:  The differences between shunt and thru mode force sensing resistor technologies.

Force sensing resistors  in the shunt mode are polymer thick-film devices made up of two membranes separated by a thin air gap. One membrane contains two sets of interdigitated traces that are electronically isolated from one another, while the other is coated with a special textured, resistive ink.

Thru mode force-sensing resistors  are flexible printed circuits with two outer substrates of polyester film. Above and below a pressure-sensitive layer, silver circles with traces are positioned, followed by a conductive polymer. The two layers of the substrate are laminated together with an adhesive layer.

3.5 Matrix or Single-Point Force Sensing Resistors

Figure 4: Examples of different force sensitive resistor technologies.Force

Sensing resistors  can be configured as single-point force sensors or as a matrix array to capture pressure distribution over a large area. Pressure mapping technology refers to the use of force-sensing resistor  matrices.

Tekscan's FlexiForceTM sensors are a type of thru mode force-sensing resistor. This technology's flexibility, combined with its operating capabilities and ability to operate on simple circuitry, makes it an excellent choice for embedding into smart devices with limited space and power. FlexiForce sensors are also extremely adaptable. Size, shape,  electrical termination, electrical termination, sensitivity,  and operating temperature can all be customized to meet the needs of your application.

3.6 How are Force Sensing Resistors Used?

While there are new applications for force-sensing resistor technology every day, the majority of them fall into one of four categories:

  • Detecting or measuring the rate at which a force changes.
  • Detecting or measuring a change in force relative to another object.
  • Touch and/or contact detection
  • Detecting force thresholds to initiate some kind of action (e.g., IoT applications)

This short video gives you a better visual understanding of the various applications for force sensing resistors, specifically FlexiForce force sensing resistors.
