Fact of the Day: Technology
iPhone screens are historically made from
aluminosilicate glass that is bombarded with
ions of potassium for strength and a layer of
indium tin oxide makes it touchscreen capable,
and smaller amounts of rare earth elements
enable certain colors on display. These inputs
and processes come from and take place in
various parts of the world. The screen is also
enabled by a main PCB for display which
sources an envelope tracker from Qualcomm, a
power amplifier from Avago, and an
accelerometer and gyroscope from InvenSense
- all from different parts of California. The
display PCB also has an LED backlight retina
display driver from Texas Instruments out of
Dallas, Texas, a DRAM memory chip from
Micron out of Boise, Idaho, another power
amplifier module from Qorvo out of Greensboro,
North Carolina, an accelerometer from Bosch
Sensortec out of Gerlingen, Germany, and
another power amplifier for low band 4G PAD
module from Woburn, Massachusetts. – From
