Apple Adopting Dual Light Bar System for iPad 3 Display?


Digitimes reports that Apple is currently evaluating a pair of options for addressing issues with LED backlighting on the iPad 3, noting that the current backlight bar design used in the iPad 2 is insufficient for the higher-resolution display reportedly set to debut in the next-generation tablet.
One of the new LED light bar designs has proposed to keep the light bar in a single-bar form factor but with two LED chips inside; the other has suggested using dual-LED light bars, the sources indicated.

Apple is likely to adopt the design using dual light bars, the sources asserted, adding that BLU makers have solved issues related heat dissipation and battery consumption for the dual light bar design.
Apple is unsurprisingly expected to introduce the iPad 3 early next year, with The Wall Street Journal being the highest-profile publication to confirm that timeline. A higher-resolution "Retina" display is the most widely-claimed enhancement scheduled for the device, although several reports have indicated that Apple's suppliers are struggling to produce the displays in volume.

I have no idea what the difference is. :)


By choosing a display with higher pixel density they need more light to provide the same brightness (you loose about 50% of the light as it passes through all the display elements).

Dual light bar just means there is two strips of LED lights behind the diffuser, filters and LCD.

It's a bar! Apple is putting a bar in the iPad! You can get drinks from your iPad now!


Maybe we can find an iPhone 5 or 6 at that bar!

I hope apple can keep the 10 hour battery life.

Why have two really clever bars in there?

Surely Apple can develop one really, really, really clever bar.

Call it, like "Genius Bar" or something.

No, hang on. Think they've done that one already.

There's only reason to pursue extra pixel density and increased luminescence in a display, and it's not just because Retina Displays look sharper. If you can drive twice the number of pixels, then you can drive the standard number of pixels PER EYE. Retina Displays are the stepping stone to glasses-free 3D.

If Apple introduces a retina display on an iPad while retaining or even just staying close to the current price point, I would be very impressed.

To the posters saying that screen size affects price more than resolution, that's true in general, but you need to keep in mind that a retina resolution on an iPad is an extremely high resolution, especially for a screen this size. This pretty much has to have a big effect on price, although Apple's huge supply change and high volume of production and purchasing will probably help offset that.

Seriously, think about it. If the retina display ends up being double the current resolution, it'll be 2,048x1,536... and that's a lot of pixels! especially for such a small screen. Advanced technology like that is never cheap, especially when it's brand new. But, I think Apple providing retina displays on iPads is inevitable. It's just a question of when. But we can clearly see that apple has focused on improving the graphics power of all the iOS devices.... so, I wouldn't be surprised at all if the rumours of a retina display in a iPad 3 that comes out in the near future turn out to be true. And with Apple's talented engineering teams, I also wouldn't be surprised if they can do it while maintaining a good price point.

And, I have to say, I would LOVE to see a retina display on an iPad. Personally, for me, after seeing retina displays on the iPhone 4 and 4S... there's no going back to seeing "big" blocky pixels on my screen! :)

or by using 2 bars with a much lower pixel density (including perhaps the same) they might be able to produce an iPad that doesn't go practically black in sunlight and shut up the naysayers over said issue.

Frankly I haven't seen anyone really back up the need for a 300+dpi iPad so I'm thinking that Apple will either keep the same density or perhaps go slightly higher to something in the 1080-1200p range and conquer the outdoor issue first. More brightness, better sensor, perhaps major improvements on that oleo phobic coating with a touch of anti-glare tossed in. Any displays higher than that might be test units for the iPad 4, 5 or even 6. After all they don't design these things overnight.

I'd be sort of surprised if apple went with a "retina" display with the iPad 3 considering there still isn't a single viable competitor tablet in the game.


Android tablets have caught up significantly... but a retina display would put the iPad 3 in the clear lead again.


Now if only the iPad 3 had a card slot or some sort of expansion port ...
