Anyone on this threadhave the light bleeding or any defects? If so are you happy with them
My iPad 2 had "light leak". It was not visible under normal use, only during startup and really only in a dark room. I didn't buy the iPad 2 so I could stare at the startup screen in all it's infinite glory all day long. I bought it to use it, and when I did, there was no visible light leak.
My new iPad does not show uneven "light leak". That said, when I view the startup screen under similar conditions it's obvious that it's lighter at the edges at gets darker toward the center. Again, during normal use this is invisible. I am absolutely thrilled with the quality of the retina display on the new iPad.
You have to understand a few realities of this kind of technology, optics, color and light before you decide to swap out your iPad another three dozen times.
1. The display is lit by a collection of tiny LED backlights. The iPad 2 used 36, the new iPad is said to double that. These lights are very bright, and being produced in such quantities that there are tolerances in production. For example, at 50% brightness, all of the LED's may appear uniform while at 100% brightness some may appear brighter than others. Tolerances are likely decided based on normal use--which is not 100% brightness. Certainly not while in a dark room. This is an inescapable reality of any mass produced product.
2. Black, as a color, is created by the absence of all light. On a display like an iPad, this is really no different. It's only noticeable during the startup screen because you have such a large area saturated in black. As a result, any inconsistencies in the LED backlights will become apparent. Once you go into normal use, where the pixels fill with color, the inconsistencies are no longer visible because they are using the light.
There you go. Is uneven light leak at the startup screen evidence of inconsistencies in LED production? Sure. Is there any way around it? No. Does it have any impact on your ability to use the product to it's full extent? In the vast majority of cases, also no.
I have seen some users here reporting that they can actually see the backlights around the edges of their screens. THAT is a serious problem and should be corrected. What you are describing is not really a problem.
If Apple would simply make the startup screen a white background with a black or greyscale logo, you would never have noticed it. Come to think of it, why haven't they just done that?
