toshiba 47 lcd panel factory

Recently, I reviewed the REGZA 46SV670U, which resides at the pinnacle of Toshiba"s LCD TV line. Though one limb down on the family tree, the REGZA 47ZV650U bears a striking resemblance to its kin.

The one major difference between the two is that the top dog SV670U"s LCD panel is backlit by an array of LEDs with Local Dimming. The 47ZV650U"s panel is backlit with the more conventional CCFLs (cold cathode fluorescent lights).

But this new dynamic LED display comes at a cost. The 46" SV670U retails for $600 more than the slightly larger 47" ZV650U. Toshiba is providing you clear choices at different price points. And considering the highly respectable video performance of the 47ZV650U, this less expensive relative in the REGZA bloodline is an option worth considering.

(Editor"s Note: Toshiba also makes a 42" and a 55" version of the ZV650U series, the 42ZV650U and the 55ZV650U. Since all three models have similar specifications, this review of the 47ZV650U can apply.)

Toshiba"s 47ZV650U video performance is workmanlike solid. Compared to last year"s models, this 240Hz display would easily earn a 4.5, but the bar is constantly being raised. The audio output from the integrated speakers is fine for everyday TV viewing.

I like the inclusion of both a USB port and an SD card slot. But this REGZA lacks a LAN port to connect to Internet content. Of course, if you are not interested in fidgeting with widgets on your TV, then add an extra half point. For videophiles, Toshiba provides one of the best picture adjustment tool sets around.

The MSRP for the 47ZV650U is $1699, which is comparable with other 240Hz LCD models from many manufacturers. Surfing the web, I"m finding it in the low $1200 range, which makes this REGZA more attractive. And with the holiday season just around the corner, who knows what Santa might bring.

The screen"s CrystalCoat is touted as stopping "ambient room light reflections from washing out the picture." I still found that the viewing angle was not extremely wide. The farther off center you sat, the more washed out the picture. This is characteristic of most LCDs.

This REGZA locates all its connections in two panels on the right side of the TV. On the edge, the smaller convenience panel contains one HDMI input, one Composite Video In with stereo Audio Ins, and a USB port for uploading JPEG photos, DIVX videos or MP3 songs. Also, on the side is an SD card slot where you can play JPEG photos (no music or video files).

Next to this on the back, a larger panel includes three more HDMI inputs, two Component video (YPbPr) Ins (with matching stereo Audio Ins), one more Composite Video In (with matching stereo Audio Ins), one VGA PC input with an Audio In (stereo minijack), and an S-Video In.

The 47ZV650U does not offer a LAN port, which means that you cannot connect this TV directly to your home network and stream content off the Internet.

I imagine that we will see this web-enabled feature in future Toshibas, but none of the current models include it. Of course, judging from the numerous questions I receive about networking TVs and Blu-ray players, not adding a LAN port makes this TV easier to use.

The EPA states that this Toshiba"s On Mode Power is 156W and Standby Power Consumption is .4W. Based on the formula that the TV is on five hours a day and in Standby for the other 19, the Estimated Annual Energy Use is 287 kWh/year.

Since manufacturers are not attaching those yellow ENERGY STAR tags that you find on air conditioners and refrigerators, you will have to study the ENERGY STAR list to see how the 47ZV650U compares to other 47" TVs.

We use the test patterns to adjust black level, white level, and color bias. The player is set to output a 1080p signal, which is the native resolution of the 47ZV650U.

As far as I can tell, the picture and audio adjustment tools are the same for the 47ZV650U as they are for the 46SV670U that I reviewed earlier. I don"t wish to keep referring you back to that review, therefore, I will reuse some of that text when it applies to this TV.

Now, if you just want to pull the TV out of the box, plug it in and watch the big game, then choose one of the default Picture modes. Toshiba offers six: AutoView, Sports, Standard, Movie, Games, and PC.

Next, I set the Color Temperature, which is in the Advanced Settings Menu. Even with this adjustment, you can begin to see the amount of control that Toshiba is giving you. Usually, the choices are Cool, Normal and Warm.

The 47ZV650U offers a slider from 0 to 10. 0 being Warmest Warm and 10 being Coolest Blue. Standard mode defaults to 7. I pushed it to a neutral 5. As a reference, Movie mode defaults to 2.

For most of you Sunday morning tweakers, working through those adjustments should produce a highly satisfying picture. But for the serious squeeze-every-last-pixel-out-of-a-color-bar-test-pattern types, Toshiba provides you a robust list of fine tuning features.

Finally, the 47ZV650U sports a 240Hz LCD panel. Toshiba uses backlight scanning to jump from 120 Hz to 240. VIZIO employs the same technique and I have discussed the technology in detail in my review of the VIZIO SV471XVT. Please read it if you need a refresher.

I"ll admit that the LED backlit Toshiba 46SV670U spoiled me. It"s local dimming was luscious. This traditionally backlit 47ZV650U simply cannot reproduce such deep blacks.

But when you compare the 47ZV650U with other similarly priced 240Hz LCDs models, its performance holds up quite well. The colors are true, the image is sharp and you can tweak it to match your eye.

Video technology is definitely advancing every year and Toshiba"s PixelPure 5G 14-Bit Internal Digital Video Processing pushes this 2009 REGZA incrementally beyond last year"s HDTVs.

Though when it comes to audio performance, sometimes I believe we are mired in the last century. Yes, the 47ZV650U does employ Dolby Volume to control annoying loud commercials or fluctuations when changing channels. But the basic sound fidelity is still limited by an undermanned speaker system.

The Toshiba REGZA 47ZV650U provides the type of solid performance that you should expect from a high end 240Hz LCD. It does not match the deep richness of the LED backlit with local dimming REGZA 46SV670U. Then again, its lower price tag reflects that.

There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.IPS

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Direct LED

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.

Toshiba will turn to Sharp for the 32-inch and larger flat-panel displays used in its LCD (liquid crystal display) televisions while Sharp will procure from Toshiba the chips used in its TVs. The cooperation will begin during the year from April and will slowly build towards 2010 when two goals are expected to be reached: Sharp will supply Toshiba with 40 percent of its LCD modules and Toshiba will sell to Sharp 50 percent of the chips it needs.

The deal provides both companies with a steadier supply of vital components for LCD TVs. The market for such televisions has grown from 161 million units in 2003 to an estimated 192 million this year and is expected to keep on rising on the back of strong demand and competition.

Some of the display panels headed for Toshiba will come from a state-of-the-art ¥380 billion (US$3.36 billion) LCD manufacturing plant Sharp is building in Osaka"s Sakai City. Production is scheduled to begin in 2009. The plant will handle mother glass -- the large sheets on which several display panels are made -- of 2.85 meters by 3.05 meters. This size, dubbed 10th generation, is larger than that used by any other display manufacturer and will make the Sakai plant the world"s most advanced LCD production center.

The large glass sheets also bring a cost advantage for Sharp. The per-inch price of LCD panels drops with increases in the size of mother glass, so the panels are likely to be more competitive than those from rivals. That"s especially important in the TV market, where strong competition has made price a key to success.

Toshiba currently holds a stake in IPS Alpha Technology Ltd., an LCD manufacturing joint venture created with Panasonic and Hitachi. The IPS line uses an older 6th-generation technology and will need substantial investment if it is to remain competitive in the market.

The company highlighted five updated technologies that it hopes will distinguish its Regza LCDs from the increasingly fierce competition in the flat-panel arena. Among them: PixelPure3G (14-bit video processing designed to eliminate banding artifacts and offer improved video noise reduction); DynaLight (dynamic backlight adjustment, designed to optimize contrast); ColorBurst (wider color gamut); ClearFrame (120Hz screen refresh rate, which is said to diminish motion blur without adding flicker or reducing brightness); and CE-Link (HDMI-based control codes designed to better integrate TV and A/V sources using a single remote control). That"s a lot of trademarked terminology (similar features are offered by rival manufacturers under differing names), but they do offer evidence that Toshiba is attempting to address some of LCD technology"s weaknesses, such as poor black level and screen refresh rates as compared with plasma TVs. Whether or not they work as well as advertised will remain to be seen when the models ship in the spring and summer of 2007.

LV67 line: Toshiba"s so-called LCDVD line offers two models, the 26-inch 26LV67 and the 32-inch 32LV67. These are identical to their HL67 counterparts except for the inclusion of a built-in DVD player, and will be available in the spring as well.

HL167 line: Stepping up to the middle tier of the Regza line delivers models with full 1080p resolution (including a pixel-for-pixel native resolution mode that purists will no doubt enjoy). In addition to all of the features in the entry-level HL67 line (above), the HL167 models add ColorBurst (wide color gamut) and CE-Link compatibility (the latter with infrared passthrough, for increased interdevice communication). Models will be available in 42-inch (42HL167, March/April), 47-inch (47HL167, June/July), and 52-inch (52HL167, June/July) screen sizes.

LX177 line: At the top of the lineup is Toshiba"s flagship Cinema Series. In addition to all of the features offered on the HL167 line, these models will also deliver 120Hz refresh rate ("ClearFrame") and Ethernet connectivity. (Toshiba also hints that the Cinema Series models offer HDMI 1.3--"Deep Color and xvYCC technology for enhanced color space"--and we"re working to confirm that.) The four top tier models--the 42LX177, the 46LX177, the 52LX177, and the 57LX177--range in size from 42 to 57 inches and are scheduled to hit stores in the June/July time frame.

This is the first refresh of the Regza line since Toshiba launched the label in 2006. Toshiba will also be offering a slate of smaller, non-Regza LCD flat-panel models in sizes ranging from 15 to 23 inches.

At the Essex House in New York City today, Toshiba showcased their new REGZA™ line of flat panel LCD HDTVs with screen sizes up to 47 inches, screen resolutions up to 1920X1080 pixels (1080p) and 12-bit digital video processing.

All models feature Toshiba"s newest Cinespeed LCD panel with a panel response time of 8 milliseconds or less, a 176-degree viewing angle, 16:9 widescreen format, as well as Toshiba"s PixelPure Hi-Bit™ 12-bit digital video processing. REGZA models also offer flexible input packs that include composite, S-Video, component, HDMI and PC inputs. REGZA LCDVD™ models feature a built-in DVD player as well as Toshiba"s THINC™ RJ-45 network capability to allow direct access to JPEG images or MP3 audio files stored within the owner"s home network.

Being fed a High Definition 1080i source via Toshiba"s HD-XA1 HD-DVD player, the top of the line 47-inch 47LX196 ($4299, available July, 2006) certainly looked impressive for an LCD panel with vivid color reproduction and excellent detail. Similar to what we saw in Los Angeles earlier this month from Sony"s new Bravia XBR line, except of course, Toshiba"s largest set is 1 inch bigger than Sony"s. Coincidence? I think not.
