Know your Lumia: mobile terms explained, part two

We previously explained some of the technology featured in Lumia phones such as the Lumia 430 Dual SIM, the Lumia 640 and the Lumia 640 XL. Here is part two of mobile terms you should know.

We always welcome your comments and queries, so when reader msilvestro  wanted to know about OLED screens, we couldn’t resist responding. Here’s the answer to that, plus more information.

OLED screen


OLED stands for “organic light-emitting diode.” It is a display technology made up of small dots of organic polymer (base material of the screen) and emits light when electric current passes through it.

OLED displays have several advantages over LCD screens, being thinner, lighter and brighter. These are battery-saving screens and have better viewing angles and offer more contrast and response time compared with LCD screens.

You can read about IPS LCD display in our previous story here.


OPP stands for “object push profile” and is a Bluetooth mode that enables a Bluetooth-enabled Lumia to push (transfer) a file to another Bluetooth device such as a Surface Pro or another smartphone. You can also share contact or calendar info, document or photo, from one smartphone to another.

It is important to add that not all Bluetooth-enabled devices support OPP.

Touch screen technology: Capacitive Multipoint-Touch 

touch screen

A capacitive multipoint-touch screen is a screen you control by touching it with one or more fingers. This type of a touchscreen relies on the conductive properties of the human body and can sense even the slightest touch.

Some Lumia displays, such as the ones found on the Lumia 830 and Lumia 930, are super sensitive and can detect touch even if you’re wearing gloves.

Maximum talk time

talk time

Talk time is the total amount of time you can make or receive calls on a fully charged Lumia smartphone before the battery runs out.

Lumia devices such as the Lumia 640 XL have a maximum talk time (3G) of 23.7 hours. You can increase that talk time by juicing up your phone with the mighty Microsoft Portable Power charger.

Maximum standby time

Standby time is the total time your fully charged Lumia smartphone can receive incoming calls, e-mails or other data before the battery runs out.

It is important to note that the battery capacity for a smartphone is measured in terms of talk time and standby time.

We hope you enjoyed learning about these tech terms! Did we miss any?
