LCD stands for liquid crystal display. The initial discoveries for this technology began in the early 1900s when several people discovered and began testing the functionality of liquid crystals. The first actual working LCD was created in 1964 by George H. Heilmeier, though it was in an extremely primitive state. LCD screens first became widely available for consumers in the middle of the 90’s, after two decades of reinvigorated interest in the technology. Cathode Ray Tube (CRT) televisions and monitors began to fall in popularity in the 2000’s, with 2007 marking the turn of the tide in this battle for LCD TVs.
Comparing iPad, iPad Air, and iPad Mini screen size
The original iPad and the iPad 2 were equipped with what were, at the time, fairly decent screens. Their LCD displays were 1,024×768 pixels in resolution, with a physical size of almost 10 inches diagonally. While sizes stayed the same, the resolution of the iPad 3 increased to 2,048×1,536, essentially doubling the clarity. The ratio of pixels to physical size, called pixels per inch, nearly doubles in this case, achieving what Apple calls “retina display”.
Retina display is a term that means most people with normal eyesight cannot see any pixelation on their screen when it is held at the standard distance (about two feet away). This of course does not account for suboptimal images, such as a jpeg that was scaled up from a very small size, as that is a function of pixel data rather than pixel size. The following iPads are considered to have retina displays:
● iPad 3
● iPad 4
● iPad Air
● iPad Mini 2
● iPad Pro
The iPad Pro has not yet been released, but its main feature is that it is slightly larger than the standard iPad – meaning that it will need a higher resolution to maintain its status as a retina display device. Comparing the iPad air screen size with the iPad mini screen size, there is about a two-inch difference for the diagonal measurement. Mini 2, therefore, currently has the clearest screen.
Commonly exhibited issues
● Flickering display: this is generally a graphical issue caused by certain apps, especially when they have a memory leak. It can usually be fixed temporarily by restarting the iPad. An expert can identify which apps in particular are causing trouble.
● Burn marks: chances are this is not a burn mark, but rather a small vertical mark left by your cover’s magnetic strip. These can be cleaned with the proper chemicals, but you must take care not to scratch the screen with a harsh cloth or solution. While the glass used for iPads is very resilient (it is not clear whether it is Gorilla Glass, aluminosilicate, or some other substance), it is not invincible.
● Dead pixels: these are single malfunctioning cells on your LCD that are not displaying properly, causing that region to appear like a small black hole in the image. One common method advised to fix dead pixels is to press firmly on the screen where it is located – while this may work in some instances, it has the potential to damage many more cells, rendering your display useless. If you do not wish to risk a bad repair iPad screen problems can be fixed professionally at iRepair.
● Screen damage: many users may find themselves with a cracked iPad air screen or otherwise in need of iPad glass replacement. For an iPad cracked screen Singapore residents are in luck, as iRepair is one of the best repair shops available. There is no feasible way to “fix” a broken screen – rather, an iPad screen replacement must be made. Due to screen size, the cost of iPad 2 screen repair (for example) is generally more than iPad mini screen repair.
● Unresponsive screen: if your screen is not sensitive or is simply not working altogether, your digitizer may be broken. The digitizer is what registers your finger when you touch the screen, so without this functioning properly, your iPad is useless. The protective glass, retina LCD, and digitizer are all separate, and each is required for proper functioning. Attempting to fix any of these on your own is a long and precarious process, and definitely unadvised.
● Others include: blank screen, vertical lines on screen, abnormal brightness, nonfunctioning backlight, and unusual colors.
5 ways to avoid future screen damage
1. Purchase a case made of rubber or another material that will not slip out of your hands easily. This will help avoid drops, which is the number one way to crack the glass. Additionally, if it does fall, a rubber case will lessen the impact.
2. To prevent “burn” marks, use a non-magnetic case or one that has been tested and does not produce the marks.
3. If your iPad is jailbroken, try to limit the number of apps you use that are memory intensive. Even if you do not have a jailbroken device, keep close track of your background processes and new apps. Especially if one has a memory leak, you could be afflicted with a flickering screen.
4. Keep magnets away from the screen, try not to leave your iPad on when it is not being used, and avoid putting unnecessary pressure on the screen. All of these can create or worsen dead pixels.
5. Keep your iPad out of direct sunlight. Long exposure to the sun’s rays can damage the display, and overheating could render your device completely useless.
