Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

MAKUHARI, Japan--Toshiba plans new 55-inch televisions using a technology it says will provide better performance at a price competitive with liquid crystal displays and plasma units.

Umezu would not reveal what Toshiba and partner Canon have changed in the manufacturing process. He also said that SED televisions will sell at a premium over LCDs because they will provide a better viewing experience. Nonetheless, "it will be competitive with LCD," he said.

Price has been the sticking point for SED. Toshiba and Canon formed a joint venture around a concept a few years ago when plasma and LCD television prices were much higher. Since then, LCD prices have been dropping about 40 percent per year, and plasmas have been declining in price too. Analysts and competitors have claimed that the price declines were pushing SED to the margins. Toshiba and Canon

The first SED televisions will have a screen size of 55 inches and are set to appear in late 2007, putting it a little later than the previously postponement, and they will appear only in Japan at first. Toshiba, in fact, showed off a 55-inch prototype at the show. (The company has already shown off smaller prototypes.) Depending on sales, Toshiba and Canon will then decide whether to come out with smaller sets, or larger ones.

The performance and picture quality will also be far higher than LCDs or plasmas, he said. The contrast ratio is 50,000 to 1, far higher than LCD or plasma, he said. The response time is a millisecond, thus the image blur or ghosting that can occur with some LCDs doesn"t occur.

SED televisions will also last for 30,000 hours, putting them on par with traditional tube TVs. Power consumption of SED televisions is about half that of plasma, Umezu said, and lower than LCD.

In terms of size, SED seems to compete more directly against plasma, which are generally larger. Most LCD sets sport screens less than 40 inches. LCD TVs, however, are getting larger and are gaining traction with consumers, he said.

Toshiba and Canon demonstrated a television with a 55-inch SED screen at the Ceatac exhibition in Chiba, Japan, saying they plan to put the screens into production next year.

The companies will begin initial production of the 55-inch screens in July 2007, said Keiichiro Mori, chief specialist at Toshiba"s SED Project Team, confirming that the production of SEDs, which had been delayed several times, is on track to begin next year.

In development for 20 years, SED promises pictures that are as bright as CRTtelevisions, while consuming one-third less power than equivalent-size plasma displays, and showing none of the image delays sometimes associated with flat-panel screens.

SED offers other advantages over existing flat-panel technology, Toshiba and Canon said. For example, the screens offer a wider viewing angle than other technologies and have a contrast ratio of 100,000 to 1.

Toshiba and Canon have delayed production of the screens several times, with engineers citing the difficulty of manufacturing the screens in volume. With the first screen to be manufactured next year, these difficulties appear to have been resolved.

The SED prototypes demonstrated at Ceatec were among the most popular products on display for visitors, who lined up to get a look at them. The demonstration, held in a darkened room, consisted of three 55-inch SED televisions used to show a variety of high-definition content, including a sumo wrestling match, footage from a rock concert, and a clip from the movie "Apollo 13."

Toshiba Visual Solutions Corporation and its subsidiaries ceased to be the subsidiaries of Toshiba Group on February 28, 2018. they will continue to develop, sell, and offer repair and support services for Toshiba and REGZA-brand visual products.

First to determine if your Toshiba TV was manufactured in 2015 or later look on the TV Model label located on the back of your television for the manufacture date. The label below illustrates how to find the manufacture date (outlined in red).

An additional way to determine if your model is a 2015 or later TV look on the back of the original remote that came with your TV and if you see the phone number 855.527.2411 as in the example below:

As we stated above, the stand is a large piece of obtrusive plastic. It is a blown up version of what you see on smaller Toshiba models. The scale required to make the stand from a 32"" television support a 55"" television does not translate well. On top of this, the neck on this plastic Goliath is totally static. Getting at the ports will be hard, you will need a young, able-bodied worker with a back strong enough to lift this humungous display and turn it around.

All of these comparable LCD models have a similar peak brightness. Any TV producing more than 300 cd/m2 is bright and will be more than suitable for any room in your house, regardless of the lighting situation. More on how we test peak brightness.

We noticed a very even uniformity on the , both on all-white and all-black screens. With LCD models, we sometimes see the backlighting making uneven cloudy patches in these situations. CCFL backlighting, when done correctly, can produce a more even picture than LED lighting (especially edgelighting) because the tube lights behind the display are distributed all along the screen, rather than placed just along the edges or in clusters.

We record the luminance of every value of each of the primary colors on a 0 to 255 brightness scale and reproduce it in these gradient color strips below, matched against the ideal response. These strips are visual representations of the color curves above.

This Toshiba showed excellent retention of detail in motion. Faces were fully recognizable and tight lines remained separate and intricately rendered. Only a few colors, red particularly, had some minor drag to them, leftovers of the previous frame. We saw that some of the rectangles we move would sport some jagged edges, but this was a minor problem. Mostly, motion performance was a boon for the . More on how we test motion performance.

This Toshiba displays natively at 1080p, and very well at that. If you make sure to set the aspect ratio to Native, the will be rid of any overscan at any resolution. We saw not a single problem displaying high frequency, high contrast patterns (tightly knit lines of black and white that are difficult for most televisions) at this resolution. More on how we test resolution scaling.

This Toshiba was advertised as having a wide viewing angle in the marketing specs. We beg to differ. In fact, we tested viewing angle twice because our first set of data was not very believable, though the proximate results were approximately the same. LCD screens tend to have poor viewing angles, but you can see in the chart below that the has a narrow viewing angle, even in relation to comparable models.

The stand on this 55-incher is totally static. If you like picking up a giant television, with the possibility of tipping such a hefty investment over, then you will be happy with this Toshiba. Otherwise, you will find making connections difficult, as all the ports are on the back and there is no way to get at them without wrenching your back.

The speaker hardware Toshiba provides for the isn"t strong enough for quality sound playback. Two 7W speakers are less powerful than what most HDTVs provide, even on 32"" models.

When we played some video of New York being destroyed by an appropriate amount of explosions and machine gun fire, we noticed that the sound was canned and tinny. Coming from 55-inches of television, the sound of automatic rifles reproduced at the level of a dime store cap gun was almost laughable. Grab some external speakers and you will have a great home theater.

The USB media port on this Toshiba only supports playback of pictures and music, and only MP3s and JPEGs. These are popular formats for this type of media, but more and more MP3s are being phased out because they are low quality. MP3 was great in the days of dial-up internet, but now that we have broadband, the M4a file, like what you get from iTunes, is more popular.

Looking at all the models in this chart, it would seem like the costs much more than an ordinary LCD screen for an average year of use. When you consider that this Toshiba is a 55"" television, approximately 10"" larger than the others, resulting in about 1.5 times the total screen area, you can see that quite a bit more power should be required to light this significantly larger display. Even so, the is reasonably in line with the rest, showing that it consumes an average amount of power for an LCD.

Both of these televisions had problems with color temperature. Our money goes with the Toshiba, showing a larger error, yes, but secluded to the darkest part of the spectrum. The Toshiba also had better color curves than this LG, for overall better color accuracy.

We really liked the motion processing on this particular Toshiba model. The LG had great motion capabilities as well, allowing user control over the processing, but it just was not as strong. We will say that being able to control the processing is of greater value than overall performance because, on full blast, any film based content will look wholly strange. On the LG, you can back off the processing until film based content does not look bad, while still having some interpolation for added smoothness.

Toshiba has had a hard time with viewing angle this year. The LG, though still narrow, beats the Toshiba by more than twice the possible viewing angles.

The LG has an extra set of analog ports (both a component and composite) over the Toshiba in this comparison. We also really liked the USB media port system on the LG, which is not limited to the 47LK520, but is available on all LG models.

If you compare the Toshiba 46G310U to the JVC JLE47BC3001, the JVC costs about $150 more. This extra dough provides some LED lighting for a thinner profile, better color performance, an extra HDMI port, and a wider viewing angle. The Toshiba has a drastically larger contrast ratio and a really solid set of colors for less money. It may not look as nice physically, but at this price point, consumers want a quality picture for their money, not flashy design. The Toshiba provides the better value in this comparison.

The Toshiba has a much better contrast ratio than the JVC here, done with a much deeper black level. The shadows will be much richer on the Toshiba than the JVC.

The JVC showed an almost perfect color temperature across the entire spectrum. The strong color curves, paired with a very accurate color gamut show a really strong overall color performance that proves to be superior to the Toshiba here.

The showed us some of the best motion processing we have seen in a while. The JVC BlackCrystal 3001 was strong, but not quite up to the task of besting the Toshiba.

The ($1199 MSRP) is a large and basic television. This year, we saw televisions cramming in so much new technology, from 3D imaging to internet connectivity and LED edgelighting, that it was beginning to look like you couldn"t find a regular, old-fashioned box that would show some quality images without the extras. Toshiba stripped the of all these additions to give consumers an ordinary television with strong performance in all the major categories.

We liked what we saw with this Toshiba. The contrast ratio was excellent, stemming from a very deep black level that did not require a diminished peak brightness. The color set was mostly fantastic and the motion processing was some of the best we have seen in a while.

There were a couple drawbacks though (you would expect some at this price). The 7W speakers are an inappropriate match to a 55"" screen. The force of the picture is not supported by the weak tinny sound from the internal speakers. You can remedy this quickly with an external set. The color temperature showed some severe errors, but only at the darkest end of the spectrum where images will be so dark as to not really have any color. The biggest offense was the poor viewing angle. Even for an LCD screen, the viewing angle has narrow written all over it. Although, with such a big screen, even a narrow viewing angle will cover quite a bit of the room.

All together, this is a high performance television in this price range. We do want to emphasize how large the entire piece is. You will need to measure before you bring it home, and you should consider that it will take over the room no matter where you put it. If the size and look really bother you, consider the very similar Toshiba SL412U for approximately the same price. Otherwise, you can"t go wrong with this big screen, at this little price.
