For the last fifteen years or so, custom mechanical keyboards have been getting more and more wild. From artisan keycaps to super-specific switches to 3D-printed cases, we’ve seen it all. Well, we thought we had, until we saw this. The Finalmouse Centerpiece Keyboard features completely transparent mechanical keycaps and switches, resting on top of a fully-functional LCD screen. Why? Why the hell not?

The keyboard’s pre-loaded video skins react to the user’s typing, very much like a gaming keyboard, but the CG videos underneath can dynamically shift in real-time as they’re built in the Unreal game engine. New skins (free and paid) will be made available via a Steam app. The screen and video run on a CPU and GPU internal to the keyboard itself, with no resources taken from the attached PC. Up to three videos can be loaded and selected on the hardware.

How does it work? Finalmouse says that the screen uses a “Laminated DisplayCircuit Glass Stack.” What it looks like is a super-thin, transparent membrane beneath the switches that house hair-like electrical wiring, establishing the matrix circuit required for the keypresses to register. It’s a remarkable redesign of some fairly basic keyboard components, all sitting on top of the LCD screen.

The 65-percent board is housed in a customized CNC-milled case, with controls for the screen embedded in the side. The keys and screen itself are gasket-mounted, with linear switches based on the BlackInk design. Finalmouse says the board is “completely gamer-proof and able to withstand intense abuse,” though exactly what that means isn’t mentioned.

Shockingly, Finalmouse’s video says the keyboard will cost $349 when it goes on sale early next year. That’s a lot for a standard mechanical keyboard, but it’s less than the price of a lot of custom, boutique builds — a GMMK Pro with all the trimmings comes in at the same price, for example. Note that in order to get that mesmerizing screen, you’ll have to give up a few of the premiums associated with high-end boards, like a dedicated knob, wireless options, and swappable switches.

But who cares? If you want to get those upvotes on /r/battlestations, you’ll need the coolest, most ridiculous keyboard around. And as of 2023, that’ll be the Centerpiece. Until someone finds a way to let you literally type on water, I suppose.

Flexible configuration of the electronics. Customers can configure their SlimLine product with a wide variety of LCDs, backlights, video controllers, display overlays, pointing devices, slides and enclosures (standard or custom) to meet their specific requirements.

Additional information on the specific design aspects of the SlimLine Series is provided in the paragraphs that follow. If your application requires a low-cost LCD monitor/keyboard/pointing Device, we offer the capable SlimLine Commercial.

The SlimLine 1U (SL1) has an extremely low profile, occupying only one vertical rack unit (1U = 1.75"). Constructed from a combination of aluminum and steel to provide a rugged, cost-effective and flexible design platform, this formidable monitor/keyboard is intended for use in industrial and military applications. It achieves this ultra-low profile by hinging an LCD from behind the keyboard, such that the display lies flat (facing upward) and behind the keyboard when stowed in the rack.

A spring coil latch and machined handle firmly secure the display in its stowed position. The LCD hinges upward on continuous friction hinges such that it can be positioned at virtually any angle that the operator desires, from 0 to 90+ degrees.

Interface connectors for video, keyboard, pointing device and power are located on the rear of the enclosure, facing inward, to reduce the overall depth. By default, the monitor is configured to operate from +12 VDC or +24 VDC. Optionally, an integrated AC switching power supply is available.

The SlimLine 1U can be configured with a variety of LCD display sizes and resolutions, with options available for high brightness, sunlight readability and NVIS compliance. A variety of display overlays and surface treatments (e.g., antireflective, antiglare) are available to protect the LCD or to add other functionality and performance.

A vast assortment of commercial-, industrial-1 and military-2grade keyboards are available for integration, with or without integrated pointing devices. Multiple keyboard protocols are supported including PC (USB, PS/2, AT, XT) and SUN® (Type 5 [8-pin Mini-DIN], Type 6 [USB]), as well as custom or proprietary interfaces.

The low profile SlimLine Lite II (SL2) is the premiere, fully-integrated LCD monitor/keyboard/pointing device for 19" rack chassis applications. Although it integrates many of the same components as a laptop (i.e., LCD, keyboard, pointing device) and physically resembles one as well, its 2U high (3.50") enclosure has been designed specifically to endure the harsh environments of industrial, commercial-off-the-shelf (COTS), and military applications. The flip-up display head folds over the keyboard and pivots up using torque-adjustable friction hinges, allowing operators to optimize the viewing angle. Our design technique also ensures the smallest enclosure footprint (height and depth) in the industry.

A Rack Adaptor facilitates installation of the SlimLine Lite II into a 19" RETMA rack, functioning as both a drawer and a protective case. The SlimLine mounts to the Rack Adaptor via a pair of integrated, ball bearing slides that permit the monitor/keyboard to be slid in and out of the rack, and lock into place. A hinged bezel on the Rack Adaptor latches to the unit to prevent it from moving either horizontally or vertically when subjected to vibration while in the stowed position.

LCD faces downward (facing integrated keyboard) when in the stowed position, protecting the LCD from falling debris or external stimuli while in the rack chassis.

General Digital has created dozens of “standard” enclosures that serve as baseline designs for our customers. Inherently, these designs possess configuration flexibility allowing customers to choose the standard electronics (e.g., display, video controller, keyboard and trackball, power supply), as well as the optional electromechanical options such as display overlays (e.g., touch screens, vandal shields, heaters, EMI filters), I/O connections (e.g., video, touch, power) and other engineering services (e.g., optical bonding, film laminations).

Unlike plastic enclosures (commodity products), whose mold is usually designed for one specific display and set of control electronics, our modular and “customizable” enclosures offer superior configuration flexibility. Our modular and flexible designs permit us to readily introduce contemporary display technologies and optional electronics (e.g., heaters, touch screens, EMI filters, Smart Card [CAC] readers) with minimal modifications to our existing designs, if any.

Our products are intentionally designed to support multiple LCD display models (and other control electronics) from a variety of OEM manufacturers (e.g., Sharp, NEC, Samsung, LG, AU Optronics, etc.). This capability enables us to minimize the impact of a single suppliers’ decision to obsolete, allocate or redesign their display/electronics, upon our ability to maintain configuration control or extend the manufacture life of our products. It also allows us to provide our customers wih the best electronics to suit their application requirements.

Interface connectors on the SlimLine 1Uare located on a pair of connector panels located at the rear of the main enclosure, on either side of the display head assembly. The number and size of the connectors is limited by two factors—the amount of surface area available on the connector panel, and the amount of interface cables that can be routed along either side of the display head assembly to reach the connector panel. Connections are provided for the keyboard, pointing device, power and at least one video input source. If desired, additional connectors can be added by increasing the overall depth and/or the depth of the connector panel.

Interface connectors on the SlimLine Lite IIare located on the rear of the main enclosure. Typically, connections are provided for the keyboard, pointing device and power, as well as any connections provided on the edge card of the integrated video controller. The video controller is internally mounted at the rear of the enclosure with its edge card directly exposed to the operator to eliminate the need for expensive and space consuming interface cables. For this reason, it is very important for customers to select the proper video controller with all of the required interfaces located on the edge card. In some cases, additional interface support can be supplied, provided adequate surface area is available on the connector panel.

Watertight gaskets (e.g., closed cell, neoprene, rubber, single-sided adhesive, double-sided adhesive, O-ring). These gaskets may be provided between the LCD (or overlay) and the front bezel to prevent liquids from entering the enclosure through the display opening.

General Digital can integrate virtually any LCD display size/resolution, from almost any panel manufacturer (OEM), into our SlimLine enclosures. To assist in selecting the right panel for your application requirements, we have provided a list of commonly used or recommended panels for standard/low luminance, high brightness, sunlight readable and NVIS-compatible needs. New display models are constantly being introduced to the market by the LCD manufacturers, making it extremely difficult for us to maintain a comprehensive list. For this reason, we encourage you to speak with a Sales Engineer to share your price and performance objectives, so we can assist you in making the best display selection.

LCD backlight produces sufficient luminance for use in office, shaded and low ambient/darkness light levels. However, luminance is insufficient to overcome reflected light for use in direct sunlight.

This type of technology boosts the efficiency of the backlight’s light utilization and minimizes surface reflection of ambient light. It is a transmissive LCD module that produces high contrast images, even in bright outdoor light and direct sunlight. These displays feature a wider color reproduction range than reflective LCDs. Featuring an LED backlight, these displays consume very little power and produce very little heat, making them ideal for integration into fully sealed enclosures, which are devoid of ventilation holes and cooling fans to dissipate heat. They also provide the additional benefit of a wide operating/storage temperature (as great as -30°–85° C), so that they can endure exposure to greater internal ambient temperatures. As a design note, we have found that these panels work best when coupled with an overlay that has an antireflective (AR) coating. Overlays that inhibit transmissivity (e.g., resistive touch screen) or have antiglare (AG) coatings will significantly reduce the panel’s performance in high ambient lighting conditions. Since transmissive displays produce greater brightness from their LED backlights than traditional transflective displays, they are regarded as a better outdoor solution, as they can generate high contrast in total darkness, in direct sunlight or on a cloudy/hazy afternoon.

T-EVT technology uses the high brightness/efficiency LED backlight as a light source while minimizing the surface reflection of ambient light. The result is an LCD that produces high contrast images even in bright outdoor light or direct sunlight.

In order to mount any of the SlimLine Lite II devices into a RETMA 19" Rack Chassis, a corresponding Rack Adaptor Kit must be purchased. The specific Rack Adaptor is dependent upon the length of the SlimLine Lite II which, in turn, is dictated by both the size of the LCD as well as the keyboard. A detailed description of each adaptor kit is provided below:

A hinged door is supplied with the Rack Adaptor Kit that provides a decorative and homogeneous fascia for the SlimLine Lite II when it is stowed within the rack. It serves a secondary function of locking the display head in place when the device is subjected to shock and vibration. A cutout in the bezel fits over the handle located on the SlimLine Lite II’s LCD display head.

A pair of brackets can be purchased that are designed to provide additional restraint of the SlimLine Lite II LCD Display Head Assembly. The brackets attach to the Rack Adaptor Kit. When the SlimLine Lite II is returned to its stowed position, the brackets apply gentle pressure to the top of the LCD Display Head Assembly, preventing the Assembly from bouncing under shock or vibration.

A myriad of display enhancements and services are available such as: Sunlight Readable and/or NVIS LED backlights, optically bonded overlays, vandal shields, touch screens (various technologies), EMI/RFI filters, antireflective coatings/antiglare etching, heaters and optical bonding.

General Digital can embellish the performance of a flat screen panel with a multitude of optical, electrical or mechanical overlays in the form of products and services, as shown in the interactive graphic below.

Optical bonding is a process in which OBL adheres an overlay (e.g., touch screen, vandal shield, EMI filter, heater) over the surface of an LCD display using an index (of reflection) matched, optically clear adhesive. By using an adhesive that is index matched to the LCD and the overlay, OBL can reduce the amount of internal reflections within the Optical Stackup [display plus overlay(s)], thereby increasing the contrast of the display passively (without requiring additional power or energy). Adding an antireflective coating to the viewing surface of the overlay further improves contrast by reducing the surface reflections. The combined reduction of reflected light allows more of the LCD’s backlight brightness to reach the user’s eye without being “washed out.” Optical bonding is especially useful for applications that will be used in high ambient lighting or direct sunlight.

Optical bonding is also used to create vandal shields or to strengthen the protection in front of the LCD. Optical bonding can also be used to eliminate air gaps between the LCD and an overlay to prevent the buildup of moisture and/or condensation when exposed to high humidity.

There are several different kinds of keyboards for PCs. The most common type is a physical, external keyboard that plugs into your PC. But Windows has a built-in Accessibility tool called the On-Screen Keyboard (OSK) that can be used instead of a physical keyboard.

You don’t need a touchscreen to use the OSK. It displays a visual keyboard with all the standard keys, so you can use your mouse or another pointing device to select keys, or use a physical single key or group of keys to cycle through the keys on the screen.

Go to Start, then select Settings > Accessibility> Keyboard, and turn on the On-Screen Keyboardtoggle. A keyboard that can be used to move around the screen and enter text will appear on the screen. The keyboard will remain on the screen until you close it.

Note:To open the OSK from the sign-in screen, select theAccessibility button in the lower-right corner of the sign-in screen, and then select On-Screen Keyboard.

Scan through keys: Use this mode if you want the OSK to continually scan the keyboard. Scan mode highlights areas where you can type keyboard characters by pressing a keyboard shortcut, using a switch input device, or using a device that simulates a mouse click.

The RockJam 561 Super Kit includes a 61-key keyboard piano, a keyboard stand, a padded piano bench, keynote stickers, a music stand, and a pair of high-quality headphones.

In addition to this, this electric piano keyboard kit comes with exclusive content to Simply Piano, an apple, and an android app that will teach aspiring musicians how to play.

This intuitive keyboard comes with a power supply for use at home, but can also be powered by 6 x 1.5V Size D batteries so you can take it on stage or on the road.

The keyboard has a crisp LCD screen, and provides instructions for beginners, telling them which keys to press or chords to play while trying demo songs, making it the perfect keyboard for budding musicians.

Although the keyboard is compact, the keys themselves are full size. The sturdy and portable keyboard stand is a great way to ensure the keyboard’s stability and is very easy to fold up and take on the road.

The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer.

The monitor works with a video card, located inside the computer case, to display images and text on the screen. Most monitors have control buttons that allow you to change your monitor"s display settings, and some monitors also have built-in speakers.

Newer monitors usually have LCD (liquid crystal display) or LED (light-emitting diode) displays. These can be made very thin, and they are often called flat-panel displays. Older monitors use CRT (cathode ray tube) displays. CRT monitors are much larger and heavier, and they take up more desk space.

The keyboard is one of the main ways to communicate with a computer. There are many different types of keyboards, but most are very similar and allow you to accomplish the same basic tasks.

The Print Screen, Scroll Lock, and Pause/Break keys are at the top-right corner of the keyboard. The Print Screen key takes a picture of your screen (called a screenshot) that you can edit or save using a graphics program. Scroll Lock and Pause/Break are rarely used today, so some keyboards don"t have them.

The numeric keypadresembles a calculator keypad. Many users find that it is easier to type numbers using this keypad. On some keyboards, these keys double as arrow keys.

The mouse is another important tool for communicating with computers. Commonly known as a pointing device, it lets you point to objects on the screen, click on them, and move them.

The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.

Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.

The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.

There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.

The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.

High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.

Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.

Dot pitch represents the distance between the primary elements of the display, typically averaged across it in nonuniform displays. A related unit is pixel pitch, In LCDs, pixel pitch is the distance between the center of two adjacent pixels. In CRTs, pixel pitch is defined as the distance between subpixels of the same color. Dot pitch is the reciprocal of pixel density.

Pixel density is a measure of how densely packed the pixels on a display are. In LCDs, pixel density is the number of pixels in one linear unit along the display, typically measured in pixels per inch (px/in or ppi).

Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000∶1 means that the brightest shade (white) is 20,000 times brighter than its darkest shade (black). Dynamic contrast ratio is measured with the LCD backlight turned off. ANSI contrast is with both black and white simultaneously adjacent onscreen.

Refresh rate is (in CRTs) the number of times in a second that the display is illuminated (the number of times a second a raster scan is completed). In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time.

On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.

The size of a display is usually given by manufacturers diagonally, i.e. as the distance between two opposite screen corners. This method of measurement is inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, it was the external diameter of the glass envelope that described their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangular image was smaller than the diameter of the tube"s face (due to the thickness of the glass). This method continued even when cathode-ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3.

With the introduction of flat panel technology, the diagonal measurement became the actual diagonal of the visible display. This meant that an eighteen-inch LCD had a larger viewable area than an eighteen-inch cathode-ray tube.

Estimation of monitor size by the distance between opposite corners does not take into account the display aspect ratio, so that for example a 16:9 21-inch (53 cm) widescreen display has less area, than a 21-inch (53 cm) 4:3 screen. The 4:3 screen has dimensions of 16.8 in × 12.6 in (43 cm × 32 cm) and area 211 sq in (1,360 cm2), while the widescreen is 18.3 in × 10.3 in (46 cm × 26 cm), 188 sq in (1,210 cm2).

Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition included productive uses (i.e. besides Field of view in video games and movie viewing) such as the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.

In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."

Most modern laptops provide a method of screen dimming after periods of inactivity or when the battery is in use. This extends battery life and reduces wear.

Most modern monitors have two different indicator light colors wherein if video-input signal was detected, the indicator light is green and when the monitor is in power-saving mode, the screen is black and the indicator light is orange. Some monitors have different indicator light colors and some monitors have blinking indicator light when in power-saving mode.

Monitors that feature an aspect ratio greater than 2:1 (for instance, 21:9 or 32:9, as opposed to the more common 16:9, which resolves to 1.77:1).Monitors with an aspect ratio greater than 3:1 are marketed as super ultrawide monitors. These are typically massive curved screens intended to replace a multi-monitor deployment.

These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

Most often using nominally flat-panel display technology such as LCD or OLED, a concave rather than convex curve is imparted, reducing geometric distortion, especially in extremely large and wide seamless desktop monitors intended for close viewing range.

Newer monitors are able to display a different image for each eye, often with the help of special glasses and polarizers, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.

Raw monitors are raw framed LCD monitors, to install a monitor on a not so common place, ie, on the car door or you need it in the trunk. It is usually paired with a power adapter to have a versatile monitor for home or commercial use.

A desktop monitor is typically provided with a stand from the manufacturer which lifts the monitor up to a more ergonomic viewing height. The stand may be attached to the monitor using a proprietary method or may use, or be adaptable to, a VESA mount. A VESA standard mount allows the monitor to be used with more after-market stands if the original stand is removed. Stands may be fixed or offer a variety of features such as height adjustment, horizontal swivel, and landscape or portrait screen orientation.

A fixed rack mount monitor is mounted directly to the rack with the flat-panel or CRT visible at all times. The height of the unit is measured in rack units (RU) and 8U or 9U are most common to fit 17-inch or 19-inch screens. The front sides of the unit are provided with flanges to mount to the rack, providing appropriately spaced holes or slots for the rack mounting screws. A 19-inch diagonal screen is the largest size that will fit within the rails of a 19-inch rack. Larger flat-panels may be accommodated but are "mount-on-rack" and extend forward of the rack. There are smaller display units, typically used in broadcast environments, which fit multiple smaller screens side by side into one rack mount.

A stowable rack mount monitor is 1U, 2U or 3U high and is mounted on rack slides allowing the display to be folded down and the unit slid into the rack for storage as a drawer. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a KVM (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system.

A panel mount computer monitor is intended for mounting into a flat surface with the front of the display unit protruding just slightly. They may also be mounted to the rear of the panel. A flange is provided around the screen, sides, top and bottom, to allow mounting. This contrasts with a rack mount display where the flanges are only on the sides. The flanges will be provided with holes for thru-bolts or may have studs welded to the rear surface to secure the unit in the hole in the panel. Often a gasket is provided to provide a water-tight seal to the panel and the front of the screen will be sealed to the back of the front panel to prevent water and dirt contamination.

Van Eck phreaking is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking more generally is the process of exploiting telephone networks.
