monoprice ips ccfl backlit lcd panel wqxga manufacturer

Isn"t a higher contrast ratio better? If so theirs sucks balls. Not only that a GOOD model 55" Samsung tv doesn"t even weigh as much as this tank does. $600 and it doesn"t even offer 3D support? You people and your 30" monitors are nuts. Unless you get one for <$400 new it"s a joke. IPS or not. That of which I don"t get what is so special on if they are IPS or not. I see no tearing or any graphical flaws with any of my monitors never have. Games look just is good as my big screen playing a blu-ray movie or something from DirecTV in HD @1080.

Oh yea and for their display to be actually made by LG (One of the much cheaper LCD companies out there in pricing) This is really a joke on cost for value.

If you look beyond the offerings from major manufacturers, however, there are some good deals to be found online. Unfortunately, it’s much more difficult for us to get our hands on those screens because they often come and go before we have a chance to test them. In 2013, we managed to get an Auria EQ267W in the lab and found it be good-performing monitor at an unbeatable price. If you’re in the market for a 27-inch QHD/IPS screen, they are still available. And of course, gamers will want to check out Overlord’s Tempest X270OC, another 27-inch IPS that runs at up to 120Hz.

Today we’re checking out a unique offering from Monoprice, the 30-inch IPS LED. Yes, that’s really its name. There"s no alphabet soup to mess with. And here’s the best part: it sports a 16:10 aspect ratio. We’ve long lamented how rare this screen size has become, and we’re glad to see you can buy one in a jumbo size for such a low price.

Known merely as “Product 10734” the 30-inch IPS LED is listed (as I write this) for $689.33 at Monoprice.com. Considering the competition is both low in quantity and higher in price, it’s a steal for a monitor this big (especially one with a 16:10 aspect ratio).

Looking at our most recent reviews, the only other screen in its class is the BenQ BL3200PT, a 32-inch VA-based panel with 2560x1440 resolution and super-high contrast. But that one sports a 16:9 aspect ratio and offers only the sRGB color gamut. To find a closer match to the Monoprice, we had to go all the way back to June 2013 when we reviewed 30-inch 16:10 panels from HP and DoubleSight. The HP has since been replaced by a newer model, while you can still buy a DS-309W for around $1100.

You probably won"t want to, though. The Monoprice one-ups both competitors with the addition of a GB-r-LED backlight. The HP and DoubleSight use CCFL. Not only is the LED more energy-efficient, but it enables the wider Adobe RGB gamut. This is not something Monoprice mentions in its description; we discovered it during testing.

LED (light emitting diode) backlights are the most popular type of backlight for small and medium LCDs. A new trend has begun where even large displays such as laptops, desktop monitors, and LCD TVs have LED backlights. The advantages of LEDs are its low cost, long life, no EMI interference, low operational voltage, and ease of brightness control. One disadvantage in larger displays is that too many LEDs increase the power consumption and will generate heat as a result. However, this problem will soon be overcome.LED backlights come in several different colors: yellow-green, orange, amber, pure green, blue, and white. There are two basic LED backlight designs: Bottom (array) and edge lit. The bottom (array) lit configuration has several LEDs mounted uniformly behind the display, which provides uniformity and brighter lighting, but also consumes more power and requires thicker LED backlights. The edge-lit configuration consists of LEDs mounted to one side or corner, which offers a thinner package and consumes less power. The edge-lit design occupies 98% of the LED backlight market for small to medium LCD modules.

Electroluminescence Backlight, or EL Backlight, is a solid-state phenomenon which uses colored phosphors, not heat, to generate light. EL backlights are very thin, lightweight and provide an even light. They are available in a variety of colors, with white being the most popular for use with LCDs. While their power consumption is fairly low, they require voltages of 100 VAC @ 400Hz. This is supplied by an inverter that converts a 5, 12 or 24 VDC input to the AC output. EL backlights also have a limited life of 3,000 to 5,000 hours to half brightness. The biggest drawbacks to an EL panel is that it requires an inverter to generate the 100VAC, consistent brightness, and limited life.

Cold Cathode Fluorescent Lamp, or CCFL, backlights offer low power consumption and a very bright white light. The primary CCFL configuration used in LCD backlighting is edge lighting. A cold cathode fluorescent lamp is the light source with a diffuser distributing the light evenly across the viewing area. CCFLs require an inverter to supply the 270 to 300 VAC @ 35KHz used by the CCFL tube. They are used primarily in graphic LCDs and have a longer life – 10,000 to 20,000 hours – than EL backlights do. Their biggest drawbacks are: cold weather will reduce the light output by as much as 60%, they require an inverter to generate the 350VAC please note that the inverters do not function well at low temperatures, the light intensity cannot be varied (it is either on or off), and vibration can reduce the life expectancy of up to 50%.

LED backlighting is the most commonly used backlight for small, LCD panels. Light-emitting diodes, or LEDs, are practical components for a light source because of their small size. LED backlighting is popular due to its overall low cost, long life, variety of colors and high brightness.

LED backlights are housed in a light box that has a diffuser to evenly distribute the LED light. The light box is then mounted behind the LCD’s viewing area. The LED backlight comes in two configurations: array and edge lit. The array configuration has the LEDs mounted in a uniform, grid layout within the light box. This configuration gives off a very bright, even light. The disadvantage of an array configuration is that it requires a thick light box design to accommodate the number of LEDs required. The high number of LEDs in this configuration also means it consumes more power.

A third type of backlight option available uses an electroluminescent (EL) panel. The EL backlight is constructed of a series of different material layers that work together to create the light. The EL panel generates light when an electric current (AC power) is applied to its conductive surfaces. The advantage with EL backlighting is its low power consumption, no heat emission, and overall thin composition. EL backlighting is limiting in that it requires an invertor to generate the VAC needed to emit the light.

The last common backlight option available are cold cathode fluorescent lamps (CCFLs). CCFL backlights are a cost effective option typically found in graphic displays. The CCFL backlight for LCDs is usually configured with the lamp on the edge of a diffuser to distribute the light. An inverter is required to supply the voltage required by the fluorescent lamp. CCFLs offer a bright white light with low power consumption. This backlight option is not ideal for cold-temperature applications (less than 15°C) as the light output decreases with decreased ambient temperature.

There are many different backlight options available for your LCD. The most common types are LED, fiber optic, EL, and CCFL backlights. Cost and application of your product will have the highest influences on which backlight technology is best for your LCD.
