lcd screen keyboard factory

Boutique gaming mouse manufacturer Finalmouse has big plans for its first foray into the mechanical keyboard market. Its Finalmouse Centerpiece is an eye-catching $349 keyboard that has a screen embedded underneath its transparent keycaps and switches. The effect is that it looks like you’re typing on the screen directly, while (hopefully) maintaining the feel and tactility of traditional mechanical switches.

There’s been at least one similar attempt at this idea made in the past: the Optimus Popularis. But while the Popularis used its screen (which was only visible through its individual transparent keys) to display useful information like keyboard shortcuts, Finalmouse’s seems to be far more cosmetic.

In the trailer, we see the keyboard showing a number of different visualizations, including Matrix-style green scrolling text and nature videos. Sometimes they’re interactive — like a pool of water that dynamically splashes when you touch a corresponding key — and in one case, the keyboard is even shown running a simple interactive game. The company is calling the technology behind this combination display and mechanical switch its “DisplayCircuit Glass Stack.”

Finalmouse says the keyboard is capable of storing three skins at a time, which can be switched on the keyboard itself. Additional skins will be downloadable from an app it’s calling “The Freethinker Portal” (seriously), and it says creators will be able to upload and charge for skins they’ve created. Each skin runs on the keyboard’s built-in CPU and GPU, and Finalmouse says they’re powered by Unreal Engine 5.

My big question is what this keyboard actually feels like to type on because the Optimus Popularis was basically unusable as a regular keyboard. Reassuringly, the Finalmouse Centerpiece uses standard Cherry MX-style switches, which should guarantee a certain level of quality. It’s collaborated with switch manufacturer Gateron to develop what it’s calling a “custom autolubed linear mechanical switch” based on Gateron’s existing and generally well-liked Black Ink linear switch.

The overall layout is compact and roughly 65 percent, which means you get an arrow key cluster but no function row. It’s a little hard to get a good view of the Centerpiece’s keycaps from Finalmouse’s trailer, but they appear to be low in profile and relatively flat in contrast to the scooped keycaps found on most mechanical keyboards.

In a move that’s presumably meant to allow as much screen as possible to shine through each keycap, their legends are printed on the front (rather than the top) of each key, which I can’t imagine is going to make them easy to read — especially not when the screen is in action.

There’s also no mention of more typical enthusiast mechanical keyboard features like support for remappable keys or hot-swappable switches — which let you replace a keyboard’s switches without desoldering. The trailer is also light on other technical specs, like the resolution of its built-in display or the specifics of its switches. Finalmouse does say it connects to a computer using a single USB-C cable.

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.
