2013 R550A / W802A / W900A: 'Dynamic Edge LED Backlight"vs Local Dimming

OK, I find it very confusing.  During a session here with Sony support chat, told me "dynamic lighting is the same as the local dimming.

So wait, then.

If I understand correctly and according to the product pages, the technology of lighting for the following models of 2013 are as follows:

(Note: DELB = dynamic Edge LED backlight)

R550A:

NO DELB

Framework of gradation

W802A:

DELB

Gradation of frame (actually listed on the Spec tab)

W900A:

DELB

Local Dimming

OK, page of the 802, DELB + framework gradation means "Dynamic Edge LED backlight with gradation of framework offers scenes of dark and illuminates the light scenes. Rather than illuminate the entire screen, contrast is reinforced in all the right areas for a more realistic picture. »

If it stimulates clear areas, but also with the entire framework, which should theoretically control each region the same way that stimulate clear areas, gradation and (local) drive other areas don't?

I mean, if the 802 choking back the entire screen (this brings all regions down) and then compensate with stimulation from other regions, how is it different?

Sony R550A series and W802A series televisions incorporate the following display features.

LED backlight type

Type - Frame of gradation of gradation

However, the series of W900A TVs has Dynamic Edge LED backlight with local dimming.

All LCD TVs need lighting behind the actual LCD Panel any. The type of lighting affects the TV picture contrast, color range and black level. Some models put the LEDs on the edges of the screen; more advanced models use a grid of LEDS behind the screen divided into sections that can be activated independently on and outside, a feature called "local dimming".

The Local Dimming function refers to the ability of a LED TV to independently control the backlight for different parts of the screen. This allows the display to produce more deep contrast black and several scenes or images with a combination of dark and light elements.

Gradation of the frame is the equivalent of a light local dimming, but with even less areas. Instead change the light for a specific region of the screen, it is the frame of the screen that changes in intensity.

NOTE: The Local Dimming function works only when the image Mode is set to Standard.

  • Tecra A11 - LED backlight problem

    I have great pain in my eyes after a day of working with Tecra A11 BIOS V1.7 = BIOS update. Wenn I bought it there was 1.4 BIOS the same problem with the eyes, LED backlight killing my eyes, a lot of pain after a day's work. V1.5 and 1.6 are much better (no pain) but new BIOS 1.7 is the same eye-killer than 1.4.

    Who will help me? Users of this forum?

    I want the people of Toshiba to help me, they sell the product ready 1/2, absolutely bad work! No contacts to Toshiba just this forum. Toshiba is interested in my problem with its Tecra A11 laptop bad and stupid BIOS updates? I'm really angry, never had such problems with laptop so much. So excuse my emoutions that I'm starting to hate Toshiba for the very bad experience with this Tecra A11. Why some users of this forum should help me? I paid a lot of money to Toshiba, so I want that people of the Toshiba to tell me what they do in their BIOS updates, silly kill my eyes with LCD backlighting. How many BIOS updates will be needed to make the Tecra A11 work correctly for 800 EUROS? I'll never buy anything from Toshiba.

    Hi dusanpov,

    First of all: cool! Nobody is perfect and that these things can happen that something does not work correctly.

    I put t know what problems you have with LED backlight, but a more detailed description would be nice. A friend of me also uses the Tecra A11 but it didn t tell me questions so I think this laptop works very well.

    And I think that it of normal that there is no contact with Toshiba and you won't get any help from Toshiba because you will need to contact a * authorized service provider *. If you have a problem with your laptop, connect with these guys here. They can repair the laptop and it's free if your laptop is under warranty. On the Toshiba site, you can find a list of them.
    Check this box!

    Finally, and especially if you have noticed that with an older version of BIOS, that everything works correctly, you can get this older version of a service as well. As you can see, it might be useful to communicate with these guys here.

    If you have any other questions, just after again! :)

  • T500 LED backlight - no, Yes - when?

    If the LED backlight comes the T500 in the next few weeks/months or not?
    I've heard mixed answers from different people who have spoken on the phone to the people of lenovo. Some say that no light, some say that the LED will be available later as it is out of stock...

    Does anyone know for sure?

    People,

    T500 LED option will officially announce on 9/23. It may take a little extra time for models with this Panel to be available for purchase. W500 doesn't have a LED backlight option. Hope this helps

    My new Envy 15 t-ae000 is supposed to have a LED backlit keyboard.  I see no evidence of a backlight.  Is there something that I need to activate or something, or missing?

    I don't have the function of LED backlight on my laptop.  I found on an old post for a different model than to turn on the backlight on the keypad, press a function key.  one that has not been specified but I tried those with icons that looked like it was related to a light light and button F5 was one.  Thanks for responding to my message.

  • Problems with injection dynamically edge compositions

    Is there a way to inject the preloader script and to fire without the onload event of the window? I guess that's what he wants, but it will never come because I'm using a single HTML page and dynamically inject preloader for the composition of each Board, as required. I followed this guide , but it is useless in my situation. Pointers would be greatly appreciated!

    I also want to prevent the injection of jquery and the ship's library whenever it wants to load a new composition (as requested by this man) edge preloader. The way it's run now is superbly ineffective.

    The preloader js actually expected onload window, which is stupid. I need an option to run immediately, because I dynamically inject the preloader. I would like to see this option as a function to call on AdobeEdge.

  • LED backlight display off when the power supply is connected

    Basically, what happens is every time others or so when I plug my T420 in power, the backlight of the screen turns off completely. The screen is always on because if I look close enough I can still see whats on the screen. All the other power lights, Thinklight and other indicators remain on. I can't tell if this is a problem of motherboard, power supply problem or something different, but the problem is very frustrating because I put the computer to sleep and then wake it up back up to continue to use the machine. Any help is appreciated.

    Using the search I found this:

    Link to the Knowledge Base

    This problem is well known and seems to be a hardware error. Then try to contact the after-sales service and send in your thinkpad. Or you can use the workaround described in the link above.

  • Inspiron laptop power button: LED backlight?

    I have a new laptop Inspiron 5758. When I press the power button on this topic, the power button does not, even if there is a small translucent band on it designed to show the light from an LED behind it.

    At work, we have a few new laptops Latitude 15 and their power buttons lights up when you press.

    A Dell technical support person told me that the Inspiron buttons power lights don't hurry; the single LED on the system is a forward on the half lower case which serves as an indicator of activity combination of load and disk.

    The tech support person gave me specific information?

    There is no led on or around the power on button.

  • How to load the CSS and JavaScript of JQuery UI inside edge led

    Hi I am using the JQuery UI inside edge slider but it doesn't work, I don't know what files should I download and how to include Javascript and CSS and images of the theme within the edge life, if someone has a code example from the compistionready what should I write on it and what is the folder structure files of the user interface and how to import them?

    Thanks in advance

    What is your configuration?

    1. you need to load the file ui.js as in this example for draggable. Include the correct version of jquery UI. If you need a file css then you load too.

    () yepnope

    {

    Nope:]

    "js/jquery-ui-1.9.2.custom.min.js,"

    ' css/jquery-ui.1.9.2.custom... min.css',.

    ],

    full: init

    }

    );

    2. / then you get your code for the slider - everything you need.

    function init() {}

    var mySlider = sym.$("mySlider");

    mySlider.draggable ({disabled: false});

    mySlider.draggable ({axis: "x"});

    }

  • HTTP Dynamic Streaming works only on local computer

    Hello Adobe FMS community,

    Here is my situation: I took the 150, 500 & 700 Kbps examples of f4v files and manuelly them packaged streaming rates using f4fpackager. I then placed in < FMS installation directory >/webroot/httpDynamicStream. When I access the OSMF drive on the local computer (http://[Server's Address]/OSMFPlayer/OSMFPlayer.html LAN IP) and try to play to the URL: http://[Server's Address]/httpDynamicStream/httpDynamicStream.f4m IP LAN, everything works fine. However, when I access the OSMF player that is hosted on another server on the network ((http://[Other Machine of the LAN IP Address]/OSMFPlayer/OSMFPlayer.html and pass in the URL: http://[Server's Address]/httpDynamicStream/httpDynamicStream.f4m LAN IP, I get an error #2048.)) Could someone help me understand what the problem is here? Do I need a crossdomain.xml? If so, please give an example of one that would work.


    Thank you very much.

    Hello

    Please use HTTP Dynamic Streaming.
    As you said, you hit the error crossdomain.xml missing itself (error code 2048 confirmed). Joined a crossdomain.xml allowing all sample (and so risky for the purposes of the tests) that you can use.

    Thank you!

  • getJSON does not work?

    Hey, I want to create a dynamic edge led - animation


    So I tried to load a file json without success...

    My *.json file is located in the same directory as the files of edge - my sample code:

    $.getJSON('source.json', function(data) {
                        alert("Inside GETJSON");
                        for ( var i=0; i < data.length; i++){
                           // console.log("data[i]");
                        }
              });
    

    Or the alert is triggered, or the journal of console... :/ I have place my code in the complete section of composition of my side-project. (I dunno - that is the problem?)

    No indication or help would be great

    Darrell Hey,.

    Yes, this is the place where my code in...

    BUT

    I found the solution... My json file has a syntax error, and it seems that edge can not load, when it is not validated. (Of course there is no sign of an error in the dev-console or so...)

    So if someone has the same problem - check your json file, twice!

    Best,
    Nico
