The Sharp LC52LE700UN is one of the least expensive LED-backlit LCD available today. It uses a LED backlight technology and measures slightly more than 3” thick, rather than edge-lit technology that will allow ultra-slim design panels that can go thinner than 1”.
Setting up the LC52LE700UN
It supports a 120Hz refresh rate that allows the TV to display the proper cadence with 1080p or 24 material. This model and the 46” model feature a dejudder processing. (However, do note that for models 40” and 32”, this dejudder processing feature is not available.)
Sharp also provides Aquos Net, an interactive feature for its users, similar to Yahoo Widgets and offer similar types of content. There is an Ethernet port and once connected, users may enjoy an array of widgets including MSNBC, Nasdaq, Access Hollywood, MSNBC Sports, Rallypoint, Weatherbug, Navteq Traffic, Picasa, Screen Dreams, Astrology.com, GoComics, Funspot games, and separate widgets to display a clock, a calendar and the date. The display for widget selection is confined to a small bar on the lower right. The Net button on the remote brings users to the navigator through different displays. Users may choose to have an inset view with the widgets squeezed to a small bar on the lower right corner, a side-by-side view that splits the screen half-half for sharing between the widget and the program, or a full screen view that eliminates the widgets entirely.
Also, there is the Aquos Advantage Live. This is a customer service support where Sharp remotely connects to the system and is able to temper with the configurations and settings of the tv for customers when there are problems that need immediate attention, without having a technician over at the house.
Sharp has improved its range of picture controls with seven total picture modes, six of which can be adjusted, and among them one titled User that’s independent per input. The Auto mode, according to the manual, “optimizes the picture according to room brightness and video signal”. A full color management system is available, along with a “fine mode enhanced” setting that improves motion resolution. There’s also a film mode to control 2:3 pull-down.
There are plenty of controls that helps improve the color accuracy slightly. The color management system worked well and users may improve the magenta and yellow secondary colors and color decoding. Users may actually favor watching image with the Active Contrast disabled. The feature brightens or dims the entire backlight according to the content, improving some black levels, but this compromised the quality of other items within the display. Thankfully, though, there is no fluctuating backlight and also lacks the blooming artifact on local dimming modes.
This model has an issue with the grayscale in mid-to-bright areas that are somewhat inaccurate, and become even less accurate after calibration. However, this system displays primary colors pretty well. There is a bluish/reddish tinge to very dark and black areas. However, this discoloration can be overlooked.
There are two strengths for the dejudder processing. There is little effect engaging the dejudder function, in fact it made film-based material look artificially smooth. There are artifacts in the Advance High mode.
The system handles 1080p/24 sources well. For 1080i and 1080p sources, users are recommended to use one “Dot by Dot” feature in the four aspect ratio options for HD sources. This helps scale the sources correctly without introducing any overscan. There is no picture-in-picture, but includes an option to freeze the onscreen image momentarily.
The Aquos Advantage Life is Sharp’s support feature with the best onscreen help. Users are given a toll-free customer service phone number and a unique “connection number” that users give to the customer service representative. The representative then connects to the tv remotely, gaining control to change settings, calibrations, troubleshooting and even see the connections to the tv via HDMI. An average user with the least technical knowledge will appreciate this feature very much.
The Aquos Net is impressive. For some areas, the Traffic widget showed real-time traffic updates for some locations (note: we do not know if it applies worldwide), a feature that no other interactive TV provides. Weather information is detailed and included a Doppler radar map of the area. Picasa worked well and helped load images and slideshows quickly with excellent resolution.
However, the Access Hollywood widget never loaded. The fantasy football service is not active, unlike the Rallycast Yahoo widget. The inset widget icons are merely buttons to launch the half-screen widgets and does not offer custom information of their own. At this moment, seems like these widgets are not fully developed yet. Sometimes the function freezes too, and there may be the problems about the numeric keypads not functioning.
Pros and Cons
However, the black levels are not as deep as LED and some non-LED based LCDs. There is less accuracy for grayscale and the glossy screen reflects ambient lights. There is also some issues with backlight uniformity. Also, the Aquos Net widgets may not be sufficient for some users.
The review above applies to all other models in the LE700UN series, including LC-52LE500UN for 52”, LC-46LE700UN for 46”, LC-40LE700UN for 40” and LC-32LE700UN for 32”. However, the 32” has a different screen coating on its LCD panel. The 40” model also does not have dejudder processing. Other than these, the four models are very similar in picture quality.
