There are PC builders out there that can put a system together, check its function to make sure everything is running smoothly, and then use it without ever looking at its vital signs again.

Recently though, Lamptron has shifted their attention to PC monitoring hardware. They currently offer more than ten different hardware monitors in different sizes and styles, with more on the way!

First and foremost, Lamptron’s hardware monitors currently all offer the same user interface and functionality. Powered by a micro USB connection and interfacing with your PC by way of a full-sized HDMI connection, they’re universal and easy to use.

AIDA64 is capable of monitoring nearly every piece of data about your PC and displaying it on the Lamptron System Monitors. Anything from memory utilization to disk activity to per-core CPU temperatures. Temps, voltages, clock speeds, power values, disk space – pretty much anything you might want to know about what your PC is doing can be monitored in real time and displayed.

What’s more, AIDA64 allows you to build a completely custom screen for your new monitor. You can decide not only which pieces of data are displayed, but customize the way they’re displayed. Bars, graphs, gauges, simple numbers – the choice is yours. You can customize nearly every aspect of your screen, right down to the color and font used in the different data displays and more. You can add your own images and even make your own custom gauges if you’re savvy with image editing software.

The HM022 is the smallest of the monitors that Lamptron offers, with a diminutive 2.2-inch LCD. Why would you want a monitor with a screen that small, you ask? Because this one is built into a graphics card support bracket.

The HC060 monitor offers a six-inch LCD screen and comes with mounts to install in any dual 5.25” position in a PC case. Fully enclosed and only 6mm thick, the HC060 can also be housed outside your PC case, though no mounts or stands are included for this purpose.

Moving up in screen size brings us to the HC070. Offering a 7-inch screen and matching the 6mm thickness of the HC060, the HC070 is designed to mount in a PCI slot inside your case.

The HM070 monitor is a modification of the HC070. While using the same 7-inch screen, it provides an enclosure 10mm thick that allows it to function freestanding outside of the PC case. It also includes the same mounting options as the HC070.

A further modification of the HC070, the HM070 LIFT places the 7-inch LCD screen in a larger housing that’s 30mm thick and includes an option for wall mounting.

Though the screen on the HM088 is an 8.8” LCD, its form factor is longer and narrower than the 070 series. Designed to be mounted inside your PC case in a PCI location, its length will cover a large portion of most side panel windows.

The HM101 moves away from the smaller screens used in previous models, offering a 10.1-inch LCD and includes a single-position stand for placing it on a desk.

An evolution of the HM101, the HM101 Touch has the same screen size, but the bezel is larger and notably thicker along one of the long edges. Touch-control enabled, the HM101 Touch has a virtual keyboard function that allows the user to interact with the monitor directly.

Similar to the HM088, the HM140 offers a long narrow form factor, but with a full 14-inch LCD screen. Mounting for inside the PC case is included. While it is 14mm thick, the shape of the HM140 will not allow freestanding use without a stand of some sort.

The HM140 Touch brings a screen identical in size to the HM140, but wrapped in a thicker bezel and including the same multi-position stand that comes with the HM101 Touch. Virtual keyboard support is also present.

The largest of Lamptron’s monitors, the HM173 is a gargantuan 17.3 inches of screen. Sharing the same uniform narrow bezel as the HM101, it also comes a non-adjustable single-position stand.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

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.

Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.

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.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.

-If you crack LCD screens and find the liquid crystal leakage, don’t panic. Just remember that the liquid crystal materials might not be more toxic than your detergents for stove or washroom. Just wash your hands with soup throughout. Never try to play with it or even worse to taste it. The liquid of the cracked computer screen will not evaporate, no emissions worries.

-Any electronics has environment impact and can’t be used landfills. If you want to get rid of old LCD monitors or LCD TVs, give them to electronic collection stations. Let’s the professionals to handle them. They will extract some precious metals/parts and make them into something useful or at least not hazard. FYI, liquid crystal materials are retrievable.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

A laptop computer or notebook computer, also laptop or notebook for short, is a small, portable personal computer (PC) that is designed to be practically placed on the user"s lap, hence the name. Laptops typically have a clam shell form factor with a flat panel screen (usually 11–17 in or 280–430 mm in diagonal size) on the inside of the upper lid, and an alphanumeric keyboard (typically QWERTY) on the inside of the lower lid, although 2-in-1 PCs with a detachable keyboard are often marketed as laptops or as having a "laptop mode".pointing device such as a trackpad or trackpoint. Many modern laptops also have a built-in webcam and even a touch screen display.

Laptops combine many of the input/output components and capabilities of a desktop computer, including the display screen, small speakers, a keyboard, data storage device, pointing devices (such as a touch pad or pointing stick), with an operating system, a processor (Central processing unit (CPU)) and memory into a single unit. Most modern laptops feature integrated webcams and built-in microphones, while many also have touchscreens. Laptops can be powered either from an internal battery or by an external power supply from an AC adapter. Hardware specifications, such as the processor speed and memory capacity, significantly vary between different types, models and price points.

Design elements, form factor and construction can also vary significantly between models depending on the intended use. Examples of specialized models of laptops include rugged notebooks for use in construction or military applications, as well as low production cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or traveling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes.

As the personal computer (PC) became feasible in 1971, the idea of a portable personal computer soon followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968,Dynabook".IBM PALM processor.IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.

As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first "laptop-sized notebook computer" was the Epson HX-20,Suwa Seikosha"s Yukio Yokozawa in July 1980,COMDEX computer show in Las Vegas by Japanese company Seiko Epson in 1981,LCD screen, a rechargeable battery, and a calculator-size printer, in a 1.6 kg (3.5 lb) chassis, the size of an A4 notebook.

The portable micro computer Portal of the French company R2E Micral CCMC officially appeared in September 1980 at the Sicob show in Paris. It was a portable microcomputer designed and marketed by the studies and developments department of R2E Micral at the request of the company CCMC specializing in payroll and accounting. It was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. It was equipped with a central 64 KB RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (separate blocks), a 32-character screen, a floppy disk: capacity = 140,000 characters, of a thermal printer: speed = 28 characters / second, an asynchronous channel, asynchronous channel, a 220 V power supply. It weighed 12 kg and its dimensions were 45×45×15cm. It provided total mobility. Its operating system was aptly named Prologue.

The Osborne 1, released in 1981, was a luggable computer that used the Zilog Z80 CPU and weighed 24.5 pounds (11.1 kg).cathode-ray tube (CRT) screen, and dual 5.25 in (13.3 cm) single-density floppy drives. Both Tandy/RadioShack and Hewlett-Packard (HP) also produced portable computers of varying designs during this period.flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The US$8,150 (equivalent to $22,880 in 2021) GRiD Compass 1101, released in 1982, was used at NASA and by the military, among others. The Sharp PC-5000,Gavilan SC released in 1983. The Gavilan SC was described as a "laptop" by its manufacturer,Toshiba T1100 won acceptance not only among PC experts but the mass market as a way to have PC portability.

Since the introduction of portable computers during the late 1970s, their form has changed significantly, spawning a variety of visually and technologically differing subclasses. Except where there is a distinct legal trademark around a term (notably, Ultrabook), there are rarely hard distinctions between these classes and their usage has varied over time and between different sources. Since the late 2010s, the use of more specific terms has become less common, with sizes distinguished largely by the size of the screen.

There were in the past a number of marketing categories for smaller and larger laptop computers; these included "subnotebook" models, low cost "netbooks", and "ultra-mobile PCs" where the size class overlapped with devices like smartphone and handheld tablets, and "Desktop replacement" laptops for machines notably larger and heavier than typical to operate more powerful processors or graphics hardware.gaming laptop" or a "mobile workstation" for professional use.

The latest trend of technological convergence in the portable computer industry spawned a broad range of devices, which combined features of several previously separate device types. The hybrids, convertibles, and 2-in-1s emerged as crossover devices, which share traits of both tablets and laptops. All such devices have a touchscreen display designed to allow users to work in a tablet mode, using either multi-touch gestures or a stylus/digital pen.

Internally, a display was usually a Liquid-crystal display (LCD) panel, although occasionally organic light-emitting diode (OLED)s are used. Since 2020, more and more laptops with OLED screens are being released relative to models with LCD screens.

In the past, there was a broader range of marketing terms (both formal and informal) to distinguish between different sizes of laptops. These included Netbooks, subnotebooks, Ultra-mobile PC, and Desktop replacement computers; these are sometimes still used informally, although they are essentially dead in terms of manufacturer marketing.

As of 2021, mainstream consumer laptops tend to come with 11", 13" or 15"-16" screens; 14" models are more popular among business machines. Larger and smaller models are available, but less common – there is no clear dividing line in minimum or maximum size. Machines small enough to be handheld (screens in the 6–8" range) can be marketed either as very small laptops or "handheld PCs," while the distinction between the largest laptops and "All-in-One" desktops is whether they fold for travel.

Having a higher resolution display allows more items to fit onscreen at a time, improving the user"s ability to multitask, although at the higher resolutions on smaller screens, the resolution may only serve to display sharper graphics and text rather than increasing the usable area. Since the introduction of the MacBook Pro with Retina display in 2012, there has been an increase in the availability of "HiDPI" (or high Pixel density) displays; as of 2022, this is generally considered to be anything higher than 1920 pixels wide. This has increasingly converged around 4K (3840-pixel-wide) resolutions.

There has been a wide range of CPUs designed for laptops available from both Intel, AMD, and other manufacturers. On non-x86 architectures, Motorola and IBM produced the chips for the former PowerPC-based Apple laptops (iBook and PowerBook). Between around 2000 to 2014, most full-size laptops had socketed, replaceable CPUs; on thinner models, the CPU was soldered on the motherboard and was not replaceable or upgradable without replacing the motherboard. Since 2015, Intel has not offered new laptop CPU models with pins to be interchangeable, preferring ball grid array chip packages which have to be soldered;

As of 2022, many laptops no longer contain space for a 2.5" drive, accepting only M.2 cards; a few of the smallest have storage soldered to the motherboard. For those that can, they can typically contain a single 2.5-inch drive, but a small number of laptops with a screen wider than 15 inches can house two drives.

An alphanumeric keyboard is used to enter text, data, and other commands (e.g., function keys). A touchpad (also called a trackpad), a pointing stick, or both, are used to control the position of the cursor on the screen, and an integrated keyboard

An external keyboard and mouse may be connected using a USB port or wirelessly, via Bluetooth or similar technology. Some laptops have multitouch touchscreen displays, either available as an option or standard. Most laptops have webcams and microphones, which can be used to communicate with other people with both moving images and sound, via web conferencing or video-calling software.

In the past, a PC Card (formerly PCMCIA) or ExpressCard slot for expansion was often present on laptops to allow adding and removing functionality, even when the laptop is powered on; these are becoming increasingly rare since the introduction of USB 3.0. Some internal subsystems such as Ethernet, Wi-Fi, or a wireless cellular modem can be implemented as replaceable internal expansion cards, usually accessible under an access cover on the bottom of the laptop. The standard for such cards is PCI Express, which comes in both mini and even smaller M.2 sizes. In newer laptops, it is not uncommon to also see Micro SATA (mSATA) functionality on PCI Express Mini or M.2 card slots allowing the use of those slots for SATA-based solid-state drives.

Waste heat from the operation is difficult to remove in the compact internal space of a laptop. The earliest laptops used passive cooling; this gave way to heat sinks placed directly on the components to be cooled, but when these hot components are deep inside the device, a large space-wasting air duct is needed to exhaust the heat. Modern laptops instead rely on heat pipes to rapidly move waste heat towards the edges of the device, to allow for a much smaller and compact fan and heat sink cooling system. Waste heat is usually exhausted away from the device operator towards the rear or sides of the device. Multiple air intake paths are used since some intakes can be blocked, such as when the device is placed on a soft conforming surface like a chair cushion. Secondary device temperature monitoring may reduce performance or trigger an emergency shutdown if it is unable to dissipate heat, such as if the laptop were to be left running and placed inside a carrying case. Aftermarket cooling pads with external fans can be used with laptops to reduce operating temperatures.

In some laptops, solar panels are able to generate enough solar power for the laptop to operate.One Laptop Per Child Initiative released the OLPC XO-1 laptop which was tested and successfully operated by use of solar panels.OLPC XO-3 laptop with these features. The OLPC XO-3 can operate with 2 watts of electricity because its renewable energy resources generate a total of 4 watts.Samsung has also designed the NC215S solar–powered notebook that will be sold commercially in the U.S. market.

A common accessory for laptops is a laptop sleeve, laptop skin, or laptop case, which provides a degree of protection from scratches. Sleeves, which are distinguished by being relatively thin and flexible, are most commonly made of neoprene, with sturdier ones made of low-resilience polyurethane. Some laptop sleeves are wrapped in ballistic nylon to provide some measure of waterproofing. Bulkier and sturdier cases can be made of metal with polyurethane padding inside and may have locks for added security. Metal, padded cases also offer protection against impacts and drops. Another common accessory is a laptop cooler, a device that helps lower the internal temperature of the laptop either actively or passively. A common active method involves using electric fans to draw heat away from the laptop, while a passive method might involve propping the laptop up on some type of pad so it can receive more airflow. Some stores sell laptop pads that enable a reclining person on a bed to use a laptop.

Some of the components of recent models of laptops reside inside. Replacing most of its components, such as keyboard, battery, hard disk, memory modules, CPU cooling fan, etc., requires removal of its either top or bottom part, removal of the motherboard, and returning them.

Productivity: Using a laptop in places where a desktop PC cannot be used can help employees and students to increase their productivity on work or school tasks, such as an office worker reading their work e-mails during an hour-long commute by train, or a student doing their homework at the university coffee shop during a break between lectures, for example.

Up-to-date information: Using a single laptop prevents fragmentation of files across multiple PC"s as the files exist in a single location and are always up-to-date.

Size: Laptops are smaller than desktop PCs. This is beneficial when space is at a premium, for example in small apartments and student dorms. When not in use, a laptop can be closed and put away in a desk drawer.

Battery: a charged laptop can continue to be used in case of a power outage and is not affected by short power interruptions and blackouts, an issue that is present with desktop PC"s.

All-in-One: designed to be portable, most modern laptops have all components integrated into the chassis. For desktops (excluding all-in-ones) this is usually divided into the desktop "tower" (the unit with the CPU, hard drive, power supply, etc.), keyboard, mouse, display screen, and optional peripherals such as speakers.

A laptop"s integrated screen often requires users to lean over for a better view, which can cause neck or spinal injuries. A larger and higher-quality external screen can be connected to almost any laptop to alleviate this and to provide additional screen space for more productive work. Another solution is to use a computer stand.

Laptops are less durable than desktops/PCs. However, the durability of the laptop depends on the user if proper maintenance is done then the laptop can work longer.

Because of their portability, laptops are subject to more wear and physical damage than desktops, additionally hindered by their integrated nature. A liquid spill onto the keyboard, while a minor issue with a desktop system, can damage the internals of a laptop and destroy the computer, result in a costly repair or entire replacement of laptops. One study found that a laptop is three times more likely to break during the first year of use than a desktop.microfiber cloth for the screen and keyboard, compressed air for getting dust out of the cooling fan, and a cleaning solution. Harsh chemicals such as bleach should not be used to clean a laptop, as they can damage it.

Laptops rely on extremely compact cooling systems involving a fan and heat sink that can fail from blockage caused by accumulated airborne dust and debris. Most laptops do not have any type of removable dust collection filter over the air intake for these cooling systems, resulting in a system that gradually conducts more heat and noise as the years pass. In some cases, the laptop starts to overheat even at idle load levels. This dust is usually stuck inside where the fan and heat sink meet, where it can not be removed by a casual cleaning and vacuuming. Most of the time, compressed air can dislodge the dust and debris but may not entirely remove it. After the device is turned on, the loose debris is reaccumulated into the cooling system by the fans. Complete disassembly is usually required to clean the laptop entirely. However, preventative maintenance such as regular cleaning of the heat sink via compressed air can prevent dust build-up on the heat sink. Many laptops are difficult to disassemble by the average user and contain components that are sensitive to electrostatic discharge (ESD).

The major brands usually offer good service and support, including well-executed documentation and driver downloads that remain available for many years after a particular laptop model is no longer produced. Capitalizing on service, support, and brand image, laptops from major brands are more expensive than laptops by smaller brands and ODMs. Some brands specialize in a particular class of laptops, such as gaming laptops (Alienware), high-performance laptops (HP Envy), netbooks (EeePC) and laptops for children (OLPC).

Case modding took off in the late 90s, and taught us all that computers could (and should!) look awesome. Much of the aesthetic went mainstream, and now tons of computer cases come with lights and windows and all the rest. [WysWyg_Protogen] realized those simple case windows could be way cooler with a neat LCD hack, and set to work.

The concept is simple. Take an old LCD monitor, remove the backlight and extraneous hardware, and then install it to the window in a computer case. When lit from behind via LEDs in the case, the screen creates a ghostly display through which the computer’s internals can still partially be seen. It’s a really compelling effect, and in theory, quite easy to achieve. All one need do is mount the stripped-down screen to the case and pipe it video from the graphics card.

In practice, it’s a little tricky. Disassembling the screen and removing things like the anti-glare coating can be tough to do without damaging the delicate panel inside. The windows typically used on computer cases can dull the effect, too. However, [WysWyg_Protogen] is continuing to tinker with the project and the results are getting increasingly impressive with each iteration. It doesn’t photograph too well, but it looks truly amazing in motion.

We often forget LCDs are transparent in their basic form, as we generally only use them with backlights or reflective backers. They really do look great when used in this transmissive way, though. Video after the break.
