To avoid reflections, the terminals where the screen plays an important part in the front design of the device receive a treatment through polarization that seeks to avoid loss of vision in direct sunlight conditions.
Given this, a dead angle ends up developing when viewing the panel with glasses that are also polarized. Knowing this, manufacturers move this black space to a situation that, due to its unusual use, bothers as little as possible, being in a margin close to the 45 percent inclination with respect to the front view of the user in front of the device.
However, with the new iPad, this blind angle has been located at an inclination very close to the vertical view, so that if we are outside and we are wearing polarized sunglasses, we will witness what we could literally see as a blackout in the screen of the third generation of iPad tablets. This situation will not occur if we observe the panel in landscape orientation, but the problem will only arise when we move the angle in a progressive inclination towards 90 degrees with respect to the horizontal perspective.
It seems that the problem that has been noticed in the new iPad is linked to the fact that it works with an IPS panel. IPS technology employs a polarized internal light system, designed to precisely allow content to be viewed without problems despite direct sunlight conditions outside. However, when displacing the blind angle that is perceived in the conditions described, they would have placed it at a point that eliminates vision if we use polarized glasses.
As detailed from the DisplayMate site, specialized in screen testing and analysis, the situation has been reproduced in some cases with the iPad itself when the terminal is oriented horizontally, while other devices do not directly suffer this incidence, regardless of the angle of inclination ”” they quote the iPhone 4 and the Samsung Galaxy Tab ””.
With this, there are already a good handful of criticisms that have crowded around the new iPad. As you know, the device with which Apple updates its catalog of tablets has been the focus of criticism for battery management, as well as overheating problems and erratic operation of Wi-Fi. In the first two cases, the Cupertino company has stepped up stating that both situations fall within what they consider normal conditions.
The long charging time is due to the increase in the amperage of the battery of the new iPad, and the false notification of full charge has to do with a security system designed to extend the useful life of the unit. On the other hand, overheating would not be so according to Apple, which has indicated that the rates of heat from the device are within the limits set out in the specifications of the device.
In the case of the problems that the Wi-Fi connection registers, they have admitted that there are defective units, inviting users to change the terminals that suffer from the failure. It also came to receive criticism for the configuration of the fourth generation LTE connection, which in Europe is not operational due to the frequency bands on which it operates. In Australia, it has even faced complaints of misleading advertising.
