The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

According to some industry expert, the ratio of global LCD to CRT production is roughly about 6:4. LCD monitors, in the past, had some defeats in certain aspects, such as brightness, contrast, visual angle, response time, lifespan and production. Along with the technical improvement, current LCD monitors are better performed in color, brightness, contrast, nearly 180-degree visual angle and response time. Plus, it has advantages in thin design, environmental friendly, and energy-saved (because of lead in the components of CRT monitors). LCD monitors have gradually replaced the CRT.

Many users might confuse LCD monitors with LCD display or LCD TV. However, the basic requirements for LCD monitors are quite different from them. For one LCD monitor, it is usually required to have higher standards on visual angle, brightness and contrast, color display ability, response time, resolution and the stability to operate continuously 24/7. Therefore, the safe electric performance and good heat emission design should be taken into the consideration for the design of one LCD monitor.

For one LCD monitor, a much broader visual angle and higher brightness and contrast are required for watching the fixed video picture at long distances. For PC display, the ideal pictures can be showed if it meets the required brightness and contrast of 200 cd/m2 and 300:1 respectively. But for monitors, the brightness and contrast should be not less than 300 cd/m2 and 450:1. The quality of picture is not only related to the brightness and contrast but also the definition, color reducibility, and SNR (signal to noise ratio) specifications. In addition, the response time is also quite important for LCD monitors. Manufacturers recently have taken a lot of efforts on increasing the response speed from the early 60 ms, 30 ms and 25 ms to current 16 ms, 12 ms and 8 ms; the tailing phenomenon has been almost disappeared and has little difference with response time for CRT.

One of Satow"s latest launch--42" Color LCD monitor, ML-4200TM1. It features 3-dimension image processing to reduce the noise and avoid the interference from the bright, making the picture display more sophisticated with PAL/NTSC. Its unique DNX technology makes the image more stable while displaying the moving pictures and video. The resolution is about 1920 x 1080; brightness is 500 cd/m2 and the contrast ratio is 2000:1. The response time can be 6.5 ms. Power supply is AC 100-240V.

Many LCD display"s power is often DC 12 V, using the external AC power adapter 220V AC/12V DC; however, it could not meet the requirements of electromagnetism interference (EMI) and electromagnetism compatible electron agnetic compatibility (E-MC) for professional monitors working at factories. Take Stonesonic. It adopted the reliable built-in switch power instead that can meet the requirements of electromagnetism compatible and interference standard. So it ensures the constant working of the machine no matter under what kind of environments and its much more coordinated appear once design is also more convenient for project mounting and operation. Skyworth also highlights its internal power supply with low consumption, and its screen service expectancy exceeds 60,000 hours. The latest I2C controlling circuits, the high reliability of whole system.

The luminescence of LCD panel is realized through several lamp tubes (cathode vacuum tube). Because some of the tubers are fixed at the fringe of the panel, it is normal that the frame becomes heated when being used for a certain period. In the design of LCD monitors, Stonesonic applied the hydrodynamics theory to make the air whirlpool inside the space of the machine form the convection, and operate the heat emission through those metal parts inside at the same time, which all ensure the reliable and constant working of the machine. So it will not affect the lifespan of the monitor if the frame of the LCD feels a little heated by hand.

Stonesonic recently launched one 19"color LCD monitor built-in DVR--SCM-1980MR. It is one kind of 8-channel monitoring and recording all-in-one monitor, adopting top-quality 19" TFT LCD panel and has functions of 4-8 channels composite video simultaneous input, real-time monitoring and recording, network remote monitoring, recording backup and alarm pan/tilt controlling.

Satow Eletronic also has one 17" LCD with built-in 4-channel MPEG-4 DVR system-BL-1700T4/CP-5714CB. Adopting the latest DSP hardware compression for each channel, the resolution is quite high. It can remote monitor via network, viewing with IE Browser or client-end software. For the LCD monitor, its contrast ratio is 800:1, brightness ratio of 300 cd/m2, display color in 16.2 M.

Stonesonic and Skywor th also developed their latest products of LCD combination panel wall. For Stonesonic, its LCD combination panel wall has already been registered and approved for six patents. The hardware basic is FPG A array, using parallel high speed image processing technology. It implements multiple high speed video signal"s unify processing technology. It totally replaces the insert card combination controller and solves the problem of quantity limitation of VGA input. It possesses all the excellent DID display technology, embedded hardware combination technology, multiple image processing technology, signal switching technology. This advanced LCD combination panel wall display system has benefits of high brightness and high definition, low power consumption and long lifespan.

Stonesonic monitor is used in many different applications such as security, broadcast, industry and multi-media. Their application in security accounts for 60 to 70 percent. Its strengths are high definition in image quality; more natural color in display. Its LCD export accounts for 50 percent of their total market. Till now, Stonesonic has had sales points in over 80 countries. It targets more at European and US markets. The latest products also includes one big IP screen monitor; very easy to install within one single IP cable. It also differentiated others in self-developed chipsets for monitors. Other vendors might adopt AV chips for LCD monitor so the 3D image may be worse in quality.

A plasma display panel (PDP) is a type of flat panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches diagonal) flat panel displays to be released to the public.

Until about 2007, plasma displays were commonly used in large televisions (30 inches (76 cm) and larger). By 2013, they had lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays. Manufacturing of plasma displays for the United States retail market ended in 2014,

Plasma displays are bright (1,000 lux or higher for the display module), have a wide color gamut, and can be produced in fairly large sizes—up to 3.8 metres (150 in) diagonally. They had a very low luminance "dark-room" black level compared with the lighter grey of the unilluminated parts of an LCD screen. (As plasma panels are locally lit and do not require a back light, blacks are blacker on plasma and grayer on LCD"s.)LED-backlit LCD televisions have been developed to reduce this distinction. The display panel itself is about 6 cm (2.4 in) thick, generally allowing the device"s total thickness (including electronics) to be less than 10 cm (3.9 in). Power consumption varies greatly with picture content, with bright scenes drawing significantly more power than darker ones – this is also true for CRTs as well as modern LCDs where LED backlight brightness is adjusted dynamically. The plasma that illuminates the screen can reach a temperature of at least 1200 °C (2200 °F). Typical power consumption is 400 watts for a 127 cm (50 in) screen. Most screens are set to "vivid" mode by default in the factory (which maximizes the brightness and raises the contrast so the image on the screen looks good under the extremely bright lights that are common in big box stores), which draws at least twice the power (around 500–700 watts) of a "home" setting of less extreme brightness.

Plasma screens are made out of glass, which may result in glare on the screen from nearby light sources. Plasma display panels cannot be economically manufactured in screen sizes smaller than 82 centimetres (32 in).enhanced-definition televisions (EDTV) this small, even fewer have made 32 inch plasma HDTVs. With the trend toward large-screen television technology, the 32 inch screen size is rapidly disappearing. Though considered bulky and thick compared with their LCD counterparts, some sets such as Panasonic"s Z1 and Samsung"s B860 series are as slim as 2.5 cm (1 in) thick making them comparable to LCDs in this respect.

Wider viewing angles than those of LCD; images do not suffer from degradation at less than straight ahead angles like LCDs. LCDs using IPS technology have the widest angles, but they do not equal the range of plasma primarily due to "IPS glow", a generally whitish haze that appears due to the nature of the IPS pixel design.

Superior uniformity. LCD panel backlights nearly always produce uneven brightness levels, although this is not always noticeable. High-end computer monitors have technologies to try to compensate for the uniformity problem.

Unaffected by clouding from the polishing process. Some LCD panel types, like IPS, require a polishing process that can introduce a haze usually referred to as "clouding".

Earlier generation displays were more susceptible to screen burn-in and image retention. Recent models have a pixel orbiter that moves the entire picture slower than is noticeable to the human eye, which reduces the effect of burn-in but does not prevent it.

Earlier generation displays (circa 2006 and prior) had phosphors that lost luminosity over time, resulting in gradual decline of absolute image brightness. Newer models have advertised lifespans exceeding 100,000 hours (11 years), far longer than older CRTs.

Uses more electrical power, on average, than an LCD TV using a LED backlight. Older CCFL backlights for LCD panels used quite a bit more power, and older plasma TVs used quite a bit more power than recent models.

Fixed-pixel displays such as plasma TVs scale the video image of each incoming signal to the native resolution of the display panel. The most common native resolutions for plasma display panels are 852×480 (EDTV), 1,366×768 and 1920×1080 (HDTV). As a result, picture quality varies depending on the performance of the video scaling processor and the upscaling and downscaling algorithms used by each display manufacturer.

Early high-definition (HD) plasma displays had a resolution of 1024x1024 and were alternate lighting of surfaces (ALiS) panels made by Fujitsu and Hitachi.

A panel of a plasma display typically comprises millions of tiny compartments in between two panels of glass. These compartments, or "bulbs" or "cells", hold a mixture of noble gases and a minuscule amount of another gas (e.g., mercury vapor). Just as in the fluorescent lamps over an office desk, when a high voltage is applied across the cell, the gas in the cells forms a plasma. With flow of electricity (electrons), some of the electrons strike mercury particles as the electrons move through the plasma, momentarily increasing the energy level of the atom until the excess energy is shed. Mercury sheds the energy as ultraviolet (UV) photons. The UV photons then strike phosphor that is painted on the inside of the cell. When the UV photon strikes a phosphor molecule, it momentarily raises the energy level of an outer orbit electron in the phosphor molecule, moving the electron from a stable to an unstable state; the electron then sheds the excess energy as a photon at a lower energy level than UV light; the lower energy photons are mostly in the infrared range but about 40% are in the visible light range. Thus the input energy is converted to mostly infrared but also as visible light. The screen heats up to between 30 and 41 °C (86 and 106 °F) during operation. Depending on the phosphors used, different colors of visible light can be achieved. Each pixel in a plasma display is made up of three cells comprising the primary colors of visible light. Varying the voltage of the signals to the cells thus allows different perceived colors.

The long electrodes are stripes of electrically conducting material that also lies between the glass plates in front of and behind the cells. The "address electrodes" sit behind the cells, along the rear glass plate, and can be opaque. The transparent display electrodes are mounted in front of the cell, along the front glass plate. As can be seen in the illustration, the electrodes are covered by an insulating protective layer.

In a monochrome plasma panel, the gas is mostly neon, and the color is the characteristic orange of a neon-filled lamp (or sign). Once a glow discharge has been initiated in a cell, it can be maintained by applying a low-level voltage between all the horizontal and vertical electrodes–even after the ionizing voltage is removed. To erase a cell all voltage is removed from a pair of electrodes. This type of panel has inherent memory. A small amount of nitrogen is added to the neon to increase hysteresis.phosphor. The ultraviolet photons emitted by the plasma excite these phosphors, which give off visible light with colors determined by the phosphor materials. This aspect is comparable to fluorescent lamps and to the neon signs that use colored phosphors.

Every pixel is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel, the same as a triad of a shadow mask CRT or color LCD. Plasma panels use pulse-width modulation (PWM) to control brightness: by varying the pulses of current flowing through the different cells thousands of times per second, the control system can increase or decrease the intensity of each subpixel color to create billions of different combinations of red, green and blue. In this way, the control system can produce most of the visible colors. Plasma displays use the same phosphors as CRTs, which accounts for the extremely accurate color reproduction when viewing television or computer video images (which use an RGB color system designed for CRT displays).

Plasma displays are different from liquid crystal displays (LCDs), another lightweight flat-screen display using very different technology. LCDs may use one or two large fluorescent lamps as a backlight source, but the different colors are controlled by LCD units, which in effect behave as gates that allow or block light through red, green, or blue filters on the front of the LCD panel.

Contrast ratio is the difference between the brightest and darkest parts of an image, measured in discrete steps, at any given moment. Generally, the higher the contrast ratio, the more realistic the image is (though the "realism" of an image depends on many factors including color accuracy, luminance linearity, and spatial linearity). Contrast ratios for plasma displays are often advertised as high as 5,000,000:1.organic light-emitting diode. Although there are no industry-wide guidelines for reporting contrast ratio, most manufacturers follow either the ANSI standard or perform a full-on-full-off test. The ANSI standard uses a checkered test pattern whereby the darkest blacks and the lightest whites are simultaneously measured, yielding the most accurate "real-world" ratings. In contrast, a full-on-full-off test measures the ratio using a pure black screen and a pure white screen, which gives higher values but does not represent a typical viewing scenario. Some displays, using many different technologies, have some "leakage" of light, through either optical or electronic means, from lit pixels to adjacent pixels so that dark pixels that are near bright ones appear less dark than they do during a full-off display. Manufacturers can further artificially improve the reported contrast ratio by increasing the contrast and brightness settings to achieve the highest test values. However, a contrast ratio generated by this method is misleading, as content would be essentially unwatchable at such settings.

Each cell on a plasma display must be precharged before it is lit, otherwise the cell would not respond quickly enough. Precharging normally increases power consumption, so energy recovery mechanisms may be in place to avoid an increase in power consumption.LED illumination can automatically reduce the backlighting on darker scenes, though this method cannot be used in high-contrast scenes, leaving some light showing from black parts of an image with bright parts, such as (at the extreme) a solid black screen with one fine intense bright line. This is called a "halo" effect which has been minimized on newer LED-backlit LCDs with local dimming. Edgelit models cannot compete with this as the light is reflected via a light guide to distribute the light behind the panel.

Image burn-in occurs on CRTs and plasma panels when the same picture is displayed for long periods. This causes the phosphors to overheat, losing some of their luminosity and producing a "shadow" image that is visible with the power off. Burn-in is especially a problem on plasma panels because they run hotter than CRTs. Early plasma televisions were plagued by burn-in, making it impossible to use video games or anything else that displayed static images.

Burroughs Corporation, a maker of adding machines and computers, developed the Panaplex display in the early 1970s. The Panaplex display, generically referred to as a gas-discharge or gas-plasma display,seven-segment display for use in adding machines. They became popular for their bright orange luminous look and found nearly ubiquitous use throughout the late 1970s and into the 1990s in cash registers, calculators, pinball machines, aircraft avionics such as radios, navigational instruments, and stormscopes; test equipment such as frequency counters and multimeters; and generally anything that previously used nixie tube or numitron displays with a high digit-count. These displays were eventually replaced by LEDs because of their low current-draw and module-flexibility, but are still found in some applications where their high brightness is desired, such as pinball machines and avionics.

In 1983, IBM introduced a 19-inch (48 cm) orange-on-black monochrome display (Model 3290 Information Panel) which was able to show up to four simultaneous IBM 3270 terminal sessions. By the end of the decade, orange monochrome plasma displays were used in a number of high-end AC-powered portable computers, such as the Compaq Portable 386 (1987) and the IBM P75 (1990). Plasma displays had a better contrast ratio, viewability angle, and less motion blur than the LCDs that were available at the time, and were used until the introduction of active-matrix color LCD displays in 1992.

Due to heavy competition from monochrome LCDs used in laptops and the high costs of plasma display technology, in 1987 IBM planned to shut down its factory in Kingston, New York, the largest plasma plant in the world, in favor of manufacturing mainframe computers, which would have left development to Japanese companies.Larry F. Weber, a University of Illinois ECE PhD (in plasma display research) and staff scientist working at CERL (home of the PLATO System), co-founded Plasmaco with Stephen Globus and IBM plant manager James Kehoe, and bought the plant from IBM for US$50,000. Weber stayed in Urbana as CTO until 1990, then moved to upstate New York to work at Plasmaco.

In 1994, Weber demonstrated a color plasma display at an industry convention in San Jose. Panasonic Corporation began a joint development project with Plasmaco, which led in 1996 to the purchase of Plasmaco, its color AC technology, and its American factory for US$26 million.

In 1995, Fujitsu introduced the first 42-inch (107 cm) plasma display panel;Philips introduced the first large commercially available flat-panel TV, using the Fujitsu panels. It was available at four Sears locations in the US for $14,999, including in-home installation. Pioneer also began selling plasma televisions that year, and other manufacturers followed. By the year 2000 prices had dropped to $10,000.

In late 2006, analysts noted that LCDs had overtaken plasmas, particularly in the 40-inch (100 cm) and above segment where plasma had previously gained market share.

Until the early 2000s, plasma displays were the most popular choice for HDTV flat panel display as they had many benefits over LCDs. Beyond plasma"s deeper blacks, increased contrast, faster response time, greater color spectrum, and wider viewing angle; they were also much bigger than LCDs, and it was believed that LCDs were suited only to smaller sized televisions. However, improvements in VLSI fabrication narrowed the technological gap. The increased size, lower weight, falling prices, and often lower electrical power consumption of LCDs made them competitive with plasma television sets.

At the 2010 Consumer Electronics Show in Las Vegas, Panasonic introduced their 152" 2160p 3D plasma. In 2010, Panasonic shipped 19.1 million plasma TV panels.

Panasonic revealed this week that it has developed a new IPS LCD panel with a 1M:1 contrast ratio that is claimed to be a quality equivalent to OLED panels.

The contrast ratio is said to be 600 times that of conventional liquid crystal panels with an average contrast ratio of 1,800:1. The company said its IPS LCD technology features wide viewing angles, high brightness, and high reliability. The elevated contrast performance is produced by “integrating newly developed light-modulating cells that permit pixel-by-pixel control of backlight intensity.”

According to a company statement: “The new high-contrast IPS panel solves the problems inherent in conventional liquid crystal panels. Despite their track record in wide-ranging applications from [business-to-consumer] to [business-to-business] fields, conventional liquid crystal panels suffer black floating, white washout phenomenon, in dark parts of the display area when the backlight intensity is increased to raise brightness. When the backlight intensity is lowered to make dark parts clearer, these panels also suffer a loss in sparkle in bright parts.”

Panasonic’s new high-contrast IPS panel uses newly developed light-modulating cells, which operate based on the operating principle of liquid crystals. By integrating light-modulating cells into the display cells the amount of backlight entering the display cells can be controlled pixel by pixel to reach 1M:1 contrast level.

Furthermore, the application of Panasonic’s IPS liquid crystal technologies, developed for industrial use, has achieved a contrast of 1,000,000:1 (maximum brightness: 1,000 cd/m2, minimum brightness: 0.001 cd/m2) while maintaining features including wide viewing anglesand high light-transmission efficiency.

Consequently, the new high-contrast IPS panel can make HDR-compatible displays for professional use at broadcasting stations and video production studios, and is suitable for uses including medical monitors and automotive monitors, Panasonic said.

Panasonic will begin sampling the high-contrast IPS panels in January 2017 with production of 10- to 100-inch versions specifically for use in medical care and automotive displays slated to start in the third quarter.

Panasonic Liquid Crystal Display Co. will manufacture the panels using 8.5th-generation (G8.5) production lines and equipment for liquid crystal panel production.

Panasonic stopped production of plasma panels in 2013 and large-screen LCD panels in 2016 for the [business-to-consumer] TV market. Its remaining panel production plants in Japan produce LCD panels for business-to-business applications.

Fierce competition from rivals primarily in China and South Korea, forced Panasonic out of consumer panel production business, shutting down its last plant in Himeeji, Hyogo Prefecture, Japan last September. The company then performed final assembly of TVs using panels sourced from third-party factories.

Although the technology is competitive with OLED displays now gaining acceptance in the consumer TV marketplace, executives with Panasonic’s U.S. operations did not return requests for comment on possible future consumer applications for the new high-contrast IPS panels, either in Panasonic branded TVs or as components for other brands of TVs.

If one LCD is good, two is better, right? I"m not talking about two layer LCD. No, that"s still not quite right. LCDs have lots of layers. How about Double Stuf LCD? Nailed it.

Double Stuf LCDs have the potential to improve the contrast ratio of a display with minimal additional power draw and without needing additional LEDs, like

The problem, and what has always been LCD"s problem, is this method doesn"t block all the light. There"s no such thing as a "black" LCD pixel. Some light always leaks through, which is why LCDs have always had worse black levels and contrast compared to other technologies, like

In Hisense"s prototypes and the current version of this TV (currently only available in China), the second layer was 1080p on a 4K display. Hisense promises that when this tech reaches US shores, both layers will be 4K. This means that essentially it"s an LCD TV with a 8 million zone backlight, far more than even mini-LED has. With two 4K modules, each pixel gets a far greater ability to block the light from the backlight, greatly improving this longstanding LCD issue and improving the contrast ratio.

To further aid the overall contrast ratio, there"s still a locally dimming backlight. In the current model it has 132 zones, which on its own would be reasonable for a traditional TV.

Price-wise, Hisense is aiming to be cheaper than OLED, though probably similar-to or more than higher-end LCDs. For reference the HZ65U9E, its 65-inch model for sale in China now, is 17,999 yuan, which converts to about $2,500, £2,000, or AU$3,700.

Manufacturers have a lot of money in LCD, and that"s not changing any time soon. They"re always looking out for the next big thing, which is how we got OLED and how we"ll be getting MicroLED. Before we get to the next gen, there"s still a lot of improvement to be made with the current gen. Mini-LED is one aspect of that, and potentially so is dual-LCD. No doubt we"ll hear more about both at CES in January.
