keyboard with lcd display free sample

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.

Update: Auto correct is an absolute NIGHTMARE! I"ve been patient for months with this issue but it keeps getting worse. I have no choice but to switch to a different keyboard product. I researched the issue and it"s been ongoing for almost a year with no fix by Google! A year! Google has lost this customer. Easy to use. Wish the auto correct was better (like it was years ago) but it"s the best on the market I"ve used in recent months. I still love it and the proprietary emojis are awesome.

With the popularity of touchscreen devices, on-screen keyboards have become a common way of entering text, while physical keyboards are more commonly used for writing longer passages of text.

However, many individuals, for various reasons, are unable to use a standard keyboard or a touchscreen. These reasons can range from differentiated movement or motor control to hand and finger strength. For many people, analternative keyboardcan be one solution, but for others using a virtual or on-screen keyboard may be the way to go. An onscreen keyboard generally appears on the same display used for programs and will remain permanently visible. The keyboard can then be accessed using the computers’ pointer device. The pointer may be activated by using a standard mouse, or through the use ofalternative devicessuch as a trackball or aswitch.

Some on-screen keyboards are for typing text and some on-screen keyboards are for navigating the computer—opening programs or clicking on links, for example. Other on-screen keyboards are those that come as part of communication packages for non-verbal communication.

How will the on-screen keyboard be used? (e.g., pointing devices or in scanning mode using a switch). Consider whether a scanning mode would be required.

Will the keyboard block a portion of the desktop or open software programs? Is there an easy way to rearrange the windows so that this doesn’t get in the way of using the computer? Are two screens appropriate (one dedicated to the keyboard) or not?

Is the student directly touching the screen? Are there any positioning requirements? (e.g., is the angle of the keyboard adjustable? Does the device need a mount?)

For users with other computer access needs, is it compatible with other required technologies? Are there potential issues that may need to be resolved (e.g., using screen magnification software may result in the user not seeing the keyboard and the place they are typing at the same time without the appropriate set-up)

Is it compatible with your computer or device’s operating system? Is it compatible with the software or apps it controls (in the case of a keyboard that completes navigation functions)?

A touchscreen or touch screen is the assembly of both an input ("touch panel") and output ("display") device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.zooming to increase the text size.

The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is optional for most modern touchscreens).

The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field, heavy industry, automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display"s content.

Historically, the touchscreen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Display manufacturers and chip manufacturers have acknowledged the trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products.

One predecessor of the modern touch screen includes stylus based systems. In 1946, a patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode ray tube display (CRT) would amplify and add to the original signal. Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A, Denk, William E, "Electronic pointer for television images", issued 1949-11-08. Later inventions built upon this system to free telewriting styli from their mechanical bindings. By transcribing what a user draws onto a computer, it could be saved for future use. See US 3089918A, Graham, Robert E, "Telewriting apparatus", issued 1963-05-14.

The first finger driven touch screen was developed by Eric Johnson, of the Royal Radar Establishment located in Malvern, England, who described his work on capacitive touchscreens in a short article published in 1965Frank Beck and Bent Stumpe, engineers from CERN (European Organization for Nuclear Research), developed a transparent touchscreen in the early 1970s,In the mid-1960s, another precursor of touchscreens, an ultrasonic-curtain-based pointing device in front of a terminal display, had been developed by a team around Rainer Mallebrein[de] at Telefunken Konstanz for an air traffic control system.Einrichtung" ("touch input facility") for the SIG 50 terminal utilizing a conductively coated glass screen in front of the display.

In 1972, a group at the University of Illinois filed for a patent on an optical touchscreenMagnavox Plato IV Student Terminal and thousands were built for this purpose. These touchscreens had a crossed array of 16×16 infrared position sensors, each composed of an LED on one edge of the screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. A similar touchscreen was used on the HP-150 starting in 1983. The HP 150 was one of the world"s earliest commercial touchscreen computers.infrared transmitters and receivers around the bezel of a 9-inch Sony cathode ray tube (CRT).

In 1977, an American company, Elographics – in partnership with Siemens – began work on developing a transparent implementation of an existing opaque touchpad technology, U.S. patent No. 3,911,215, October 7, 1975, which had been developed by Elographics" founder George Samuel Hurst.World"s Fair at Knoxville in 1982.

In 1984, Fujitsu released a touch pad for the Micro 16 to accommodate the complexity of kanji characters, which were stored as tiled graphics.Sega released the Terebi Oekaki, also known as the Sega Graphic Board, for the SG-1000 video game console and SC-3000 home computer. It consisted of a plastic pen and a plastic board with a transparent window where pen presses are detected. It was used primarily with a drawing software application.

Touch-sensitive control-display units (CDUs) were evaluated for commercial aircraft flight decks in the early 1980s. Initial research showed that a touch interface would reduce pilot workload as the crew could then select waypoints, functions and actions, rather than be "head down" typing latitudes, longitudes, and waypoint codes on a keyboard. An effective integration of this technology was aimed at helping flight crews maintain a high level of situational awareness of all major aspects of the vehicle operations including the flight path, the functioning of various aircraft systems, and moment-to-moment human interactions.

In the early 1980s, General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile"s non-essential functions (i.e. other than throttle, transmission, braking, and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input.stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle"s cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC"s touchscreen which would render climate control or stereo operation impossible.

Multi-touch technology began in 1982, when the University of Toronto"s Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass. In 1985, the University of Toronto group, including Bill Buxton, developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems (see History of multi-touch).

In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen.

Sears et al. (1990)human–computer interaction of the time, describing gestures such as rotating knobs, adjusting sliders, and swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger.

An early attempt at a handheld game console with touchscreen controls was Sega"s intended successor to the Game Gear, though the device was ultimately shelved and never released due to the expensive cost of touchscreen technology in the early 1990s.

Touchscreens would not be popularly used for video games until the release of the Nintendo DS in 2004.Apple Watch being released with a force-sensitive display in April 2015.

A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point.voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.

Resistive touch is used in restaurants, factories and hospitals due to its high tolerance for liquids and contaminants. A major benefit of resistive-touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger substitute. Disadvantages include the need to press down, and a risk of damage by sharp objects. Resistive touchscreens also suffer from poorer contrast, due to having additional reflections (i.e. glare) from the layers of material placed over the screen.3DS family, and the Wii U GamePad.

Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event. Surface acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.

The Casio TC500 Capacitive touch sensor watch from 1983, with angled light exposing the touch sensor pads and traces etched onto the top watch glass surface.

A capacitive touchscreen panel consists of an insulator, such as glass, coated with a transparent conductor, such as indium tin oxide (ITO).electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Touchscreens that use silver instead of ITO exist, as ITO causes several environmental problems due to the use of indium.complementary metal-oxide-semiconductor (CMOS) application-specific integrated circuit (ASIC) chip, which in turn usually sends the signals to a CMOS digital signal processor (DSP) for processing.

Unlike a resistive touchscreen, some capacitive touchscreens cannot be used to detect a finger through electrically insulating material, such as gloves. This disadvantage especially affects usability in consumer electronics, such as touch tablet PCs and capacitive smartphones in cold weather when people may be wearing gloves. It can be overcome with a special capacitive stylus, or a special-application glove with an embroidered patch of conductive thread allowing electrical contact with the user"s fingertip.

A low-quality switching-mode power supply unit with an accordingly unstable, noisy voltage may temporarily interfere with the precision, accuracy and sensitivity of capacitive touch screens.

Some capacitive display manufacturers continue to develop thinner and more accurate touchscreens. Those for mobile devices are now being produced with "in-cell" technology, such as in Samsung"s Super AMOLED screens, that eliminates a layer by building the capacitors inside the display itself. This type of touchscreen reduces the visible distance between the user"s finger and what the user is touching on the screen, reducing the thickness and weight of the display, which is desirable in smartphones.

A simple parallel-plate capacitor has two conductors separated by a dielectric layer. Most of the energy in this system is concentrated directly between the plates. Some of the energy spills over into the area outside the plates, and the electric field lines associated with this effect are called fringing fields. Part of the challenge of making a practical capacitive sensor is to design a set of printed circuit traces which direct fringing fields into an active sensing area accessible to a user. A parallel-plate capacitor is not a good choice for such a sensor pattern. Placing a finger near fringing electric fields adds conductive surface area to the capacitive system. The additional charge storage capacity added by the finger is known as finger capacitance, or CF. The capacitance of the sensor without a finger present is known as parasitic capacitance, or CP.

In this basic technology, only one side of the insulator is coated with a conductive layer. A small voltage is applied to the layer, resulting in a uniform electrostatic field. When a conductor, such as a human finger, touches the uncoated surface, a capacitor is dynamically formed. The sensor"s controller can determine the location of the touch indirectly from the change in the capacitance as measured from the four corners of the panel. As it has no moving parts, it is moderately durable but has limited resolution, is prone to false signals from parasitic capacitive coupling, and needs calibration during manufacture. It is therefore most often used in simple applications such as industrial controls and kiosks.

Some modern PCT touch screens are composed of thousands of discrete keys,etching a single conductive layer to form a grid pattern of electrodes, by etching two separate, perpendicular layers of conductive material with parallel lines or tracks to form a grid, or by forming an x/y grid of fine, insulation coated wires in a single layer . The number of fingers that can be detected simultaneously is determined by the number of cross-over points (x * y) . However, the number of cross-over points can be almost doubled by using a diagonal lattice layout, where, instead of x elements only ever crossing y elements, each conductive element crosses every other element .

In some designs, voltage applied to this grid creates a uniform electrostatic field, which can be measured. When a conductive object, such as a finger, comes into contact with a PCT panel, it distorts the local electrostatic field at that point. This is measurable as a change in capacitance. If a finger bridges the gap between two of the "tracks", the charge field is further interrupted and detected by the controller. The capacitance can be changed and measured at every individual point on the grid. This system is able to accurately track touches.

Unlike traditional capacitive touch technology, it is possible for a PCT system to sense a passive stylus or gloved finger. However, moisture on the surface of the panel, high humidity, or collected dust can interfere with performance.

These environmental factors, however, are not a problem with "fine wire" based touchscreens due to the fact that wire based touchscreens have a much lower "parasitic" capacitance, and there is greater distance between neighbouring conductors.

Self-capacitance sensors can have the same X-Y grid as mutual capacitance sensors, but the columns and rows operate independently. With self-capacitance, the capacitive load of a finger is measured on each column or row electrode by a current meter, or the change in frequency of an RC oscillator.

Capacitive touchscreens do not necessarily need to be operated by a finger, but until recently the special styli required could be quite expensive to purchase. The cost of this technology has fallen greatly in recent years and capacitive styli are now widely available for a nominal charge, and often given away free with mobile accessories. These consist of an electrically conductive shaft with a soft conductive rubber tip, thereby resistively connecting the fingers to the tip of the stylus.

Infrared sensors mounted around the display watch for a user"s touchscreen input on this PLATO V terminal in 1981. The monochromatic plasma display"s characteristic orange glow is illustrated.

An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any opaque object including a finger, gloved finger, stylus or pen. It is generally used in outdoor applications and POS systems that cannot rely on a conductor (such as a bare finger) to activate the touchscreen. Unlike capacitive touchscreens, infrared touchscreens do not require any patterning on the glass which increases durability and optical clarity of the overall system. Infrared touchscreens are sensitive to dirt and dust that can interfere with the infrared beams, and suffer from parallax in curved surfaces and accidental press when the user hovers a finger over the screen while searching for the item to be selected.

A translucent acrylic sheet is used as a rear-projection screen to display information. The edges of the acrylic sheet are illuminated by infrared LEDs, and infrared cameras are focused on the back of the sheet. Objects placed on the sheet are detectable by the cameras. When the sheet is touched by the user, frustrated total internal reflection results in leakage of infrared light which peaks at the points of maximum pressure, indicating the user"s touch location. Microsoft"s PixelSense tablets use this technology.

The key to this technology is that a touch at any one position on the surface generates a sound wave in the substrate which then produces a unique combined signal as measured by three or more tiny transducers attached to the edges of the touchscreen. The digitized signal is compared to a list corresponding to every position on the surface, determining the touch location. A moving touch is tracked by rapid repetition of this process. Extraneous and ambient sounds are ignored since they do not match any stored sound profile. The technology differs from other sound-based technologies by using a simple look-up method rather than expensive signal-processing hardware. As with the dispersive signal technology system, a motionless finger cannot be detected after the initial touch. However, for the same reason, the touch recognition is not disrupted by any resting objects. The technology was created by SoundTouch Ltd in the early 2000s, as described by the patent family EP1852772, and introduced to the market by Tyco International"s Elo division in 2006 as Acoustic Pulse Recognition.

There are several principal ways to build a touchscreen. The key goals are to recognize one or more fingers touching a display, to interpret the command that this represents, and to communicate the command to the appropriate application.

There are two infrared-based approaches. In one, an array of sensors detects a finger touching or almost touching the display, thereby interrupting infrared light beams projected over the screen. In the other, bottom-mounted infrared cameras record heat from screen touches.

The development of multi-touch screens facilitated the tracking of more than one finger on the screen; thus, operations that require more than one finger are possible. These devices also allow multiple users to interact with the touchscreen simultaneously.

With the growing use of touchscreens, the cost of touchscreen technology is routinely absorbed into the products that incorporate it and is nearly eliminated. Touchscreen technology has demonstrated reliability and is found in airplanes, automobiles, gaming consoles, machine control systems, appliances, and handheld display devices including cellphones; the touchscreen market for mobile devices was projected to produce US$5 billion by 2009.

The ability to accurately point on the screen itself is also advancing with the emerging graphics tablet-screen hybrids. Polyvinylidene fluoride (PVDF) plays a major role in this innovation due its high piezoelectric properties, which allow the tablet to sense pressure, making such things as digital painting behave more like paper and pencil.

Much more important is the accuracy humans have in selecting targets with their finger or a pen stylus. The accuracy of user selection varies by position on the screen: users are most accurate at the center, less so at the left and right edges, and least accurate at the top edge and especially the bottom edge. The R95 accuracy (required radius for 95% target accuracy) varies from 7 mm (0.28 in) in the center to 12 mm (0.47 in) in the lower corners.

This user inaccuracy is a result of parallax, visual acuity and the speed of the feedback loop between the eyes and fingers. The precision of the human finger alone is much, much higher than this, so when assistive technologies are provided—such as on-screen magnifiers—users can move their finger (once in contact with the screen) with precision as small as 0.1 mm (0.004 in).

In addition, devices are often placed on surfaces (desks or tables) and tablets especially are used in stands. The user may point, select or gesture in these cases with their finger or thumb, and vary use of these methods.

Touchscreens are often used with haptic response systems. A common example of this technology is the vibratory feedback provided when a button on the touchscreen is tapped. Haptics are used to improve the user"s experience with touchscreens by providing simulated tactile feedback, and can be designed to react immediately, partly countering on-screen response latency. Research from the University of Glasgow (Brewster, Chohan, and Brown, 2007; and more recently Hogan) demonstrates that touchscreen users reduce input errors (by 20%), increase input speed (by 20%), and lower their cognitive load (by 40%) when touchscreens are combined with haptics or tactile feedback. On top of this, a study conducted in 2013 by Boston College explored the effects that touchscreens haptic stimulation had on triggering psychological ownership of a product. Their research concluded that a touchscreens ability to incorporate high amounts of haptic involvement resulted in customers feeling more endowment to the products they were designing or buying. The study also reported that consumers using a touchscreen were willing to accept a higher price point for the items they were purchasing.

Touchscreens can suffer from the problem of fingerprints on the display. This can be mitigated by the use of materials with optical coatings designed to reduce the visible effects of fingerprint oils. Most modern smartphones have oleophobic coatings, which lessen the amount of oil residue. Another option is to install a matte-finish anti-glare screen protector, which creates a slightly roughened surface that does not easily retain smudges.

So far, we"ve discussed almost every key you"re likely to use. But for the truly inquisitive, let"s explore the three most mysterious keys on the keyboard: PrtScn, Scroll Lock, and Pause/Break.

More obscure is SYS RQ, which shares the key with PrtScn on some keyboards. Historically, SYS RQ was designed to be a "system request," but this command is not enabled in Windows.

In most programs, pressing Scroll Lock has no effect. In a few programs, pressing Scroll Lock changes the behavior of the arrow keys and the Page Up and Page Down keys; pressing these keys causes the document to scroll without changing the position of the cursor or selection. Your keyboard might have a light indicating whether Scroll Lock is on.

Some modern keyboards come with "hot keys" or buttons that give you quick, one-press access to programs, files, or commands. Other models have volume controls, scroll wheels, zoom wheels, and other gadgets. For details about these features, check the information that came with your keyboard or computer, or go to the manufacturer"s website.

Using your keyboard properly can help avoid soreness or injury to your wrists, hands, and arms, particularly if you use your computer for long periods. Here are a few tips to help improve keyboard use:

Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers.

When you use PowerPoint for the web, we recommend that you use Microsoft Edge as your web browser. Because PowerPoint for the web runs in your web browser, the keyboard shortcuts are different from those in the desktop program. For example, you’ll use Ctrl+F6 instead of F6 for jumping in and out of the commands. Also, common shortcuts like F1 (Help) and Ctrl+O (Open) apply to the web browser – not PowerPoint for the web.

A context menu is available in Live for quick access to many commonly used menu items. To access the context menu, right-click(Win) / CTRL-click(Mac) on the part of the interface where you would like to execute a particular command. It is worth noting that Live’s context menu may sometimes contain applicable settings from the Preferences. You should change these options with care, as they will affect not only the currently selected item but the general settings of the program.

Some commands only appear in the context menu. Among these are: various options for working with the browser (see 5.1) ; the special grid marker commands for directing Auto-Warp (see 9.2.3) ; detailed options for zoom-adaptive and fixed grid line width (see 6.9) ; copying and pasting for Operator’s envelopes and oscillators (see 26.6) ; and numerous device-specific commands.

An onscreen keyboard is a software-based keyboard that is available in most operating systems, especially Microsoft Windows, and in other applications. An onscreen keyboard allows users to type text using a joystick or a pointing device. Apart from improving input options for users who are physically challenged, it also serves as an alternative to a physical keyboard. Onscreen keyboards are also known as “software” keyboards or “soft” keyboards.

To enter input, an onscreen keyboard displays a virtual keyboard on the screen for users. Any pointing device such as a mouse, pen, joystick, etc can be used to operate it. Resizable and customizable are two features of this keyboard, further it allows to change the typing mode, font, etc., as needed. Especially those from Windows 7 and later versions in certain onscreen keyboards, they are equipped with a predictive text engine, which helps in predicting the words the users may type.

However, most onscreen keyboards feature predictive text input as typing on an onscreen keyboard is slower and more difficult than on a physical keyboard.

An on-screen keyboard is an application which provides a visual keyboard on your display screen that can be used in place of a physical keyboard. The On-Screen Keyboard can be manipulated by the mouse or other pointing device and can be configured in three layouts;101 keys display (standard keyboard)

Touch Screen Keyboard is not a standalone program. It has two new keyboard types: alphabetic and alpha-numeric. These changes were made to further emphasize the comfort of using Keyboard on touch screen devices. The alphabetic layout supports all the languages installed in your system (when you change the input language, the layout on the on-screen keyboard changes as well).

Touch Screen Keyboard has several default features that accelerate and facilitate typing on a touch screen. For instance, the program will automatically add a space and press Shift after a period. If you press a key on a touch screen, you will see a small tooltip window with the corresponding character in the area not covered with your finger. You can also use for your touch-screen any of the 70 keyboard layouts included in the installation package.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.
