En ambos casos, el elemento común es la interfaz táctil. Esta parte de la pantalla, que gracias a la laminación del iPhone está unida al panel para mejorar la visualización y reducir la latencia, se compone del propio cristal de nuestro dispositivo, que funciona como aislante, y de una capa conductiva invisible . Gracias a nuestra alta conductividad, esta capa, unida a los sensores capacitivos del dispositivo, es capaz de detectar la posición de nuestros dedos con precisión.

Surely a spark of curiosity has once stalked your head when you hold any electronic device in your hands. A need to discover exactly how each component of the devices we use every day works in order to complete the tasks of our digital lives. After all, products like the iPhone or iPad work so well that almost seems like magic , and we always like to know the wizard’s tricks.

Today, for example, we’ll stop to take a closer look at the technology of our iPhone screens, which as you may know, received a major upgrade last year with the arrival of OLED panels on iPhone X. This technology, as we have already explained, allows to control each pixel individually , providing really amazing contrast levels. However, its big problem is the price of them, as we have seen in the price of the iPhone X itself.

The main technology used by Apple devices, however, is the LCD, which differs from the OLED in that it has backlighting , and therefore it is not possible to achieve such pure blacks. In this case, the light emitted by this backlight passes through two polarisers, which surround a layer of liquid crystal that allows it to reach the second polarised. The light then reaches the pixels, composed of a structure of RGB sub-pixels, in the case of the iPhone.
