Techpally infer Touchscreen sizes and their Features

I’m sure most people are now familiar with touchscreen devices, especially with the popularity of smartphones.

While there are different touchscreen devices with different screen size requirements, touch screen devices in the same category can have a different screen size.

For example, in smartphones, they can have different sizes and screen sizes, same way to TVs, smart fridge, smart billboard, etc.

Let’s now look into the main features and advantages of touchscreens and compare how these effects are shown to the front end users.


A larger screen allows more content to be displayed at any given time, Chaktty said.

 When more things are visible, however, more information competes for the user’s visual attention. 

Normally we sit further away from a big screen. A desktop monitor is placed about 60 cm away. 

A TV could be at the other end of the room. This distance gives us a better overview of the content on the screen.

According to Techpall, A touchscreen device needs to be placed much closer to the user, and for good reason: it needs to be positioned close enough for the user to touch the screen. 

However, this closeness made it difficult for me to see the “big picture” while concentrating on one detail. 

For example, an error message at the top of the screen can be easily missed if the user is concentrating on an action at the bottom of the screen.

Also, it’s difficult to see a large portion of the screen when user interfaces are simply enlarged to fill the entire screen.

 This practice can result in blurry images, and it also limits the selection on the screen. 

The zoomed interface and the user’s close proximity to the screen (close enough to touch) means that everything on the display is oversized, making it difficult to understand the information displayed.


The Nabi Big Tab is portable in that you can move it from one room to another more easily than, say, a desktop computer. 

However, its portability differs significantly from that of a small device.

 Unsurprisingly, given its size and shape, it doesn’t offer the same portability as a smaller, lighter device. But it’s striking how seldom we move this portable device given its size.

The tablet weighs 4.7 kg. That means my son can’t carry it across the room to show me something, although he often does with smaller tablets.

It also means that we use the device almost like a desktop computer – that is, a device that is permanently placed in our home – in the place where it is used most often. 

This is definitely different from our smaller tablets, which are often carried from one room to the next – even while in use.

Sharing and Privacy

The goal of the Big Tab is sharing – and for that purpose it excels very well. 

Its size and multi-touch screen are ideal for multiplayer games where teammates and rivals sit around the screen and play together or against each other. It is fun and engaging to play together on the device.

The screen size is good for sharing.

Sharing the screen of a smaller device can be invasive as viewers have to lean over the person holding the device. 

With a larger screen , everyone has more space when a group gathers around the device, says businesspal boss.

My 2 year old happily watched my 6 year old as he solved dinosaur puzzle after dinosaur puzzle without disturbing his big brother.

However, this makes it difficult to do private things on the larger screen.

For single player games or private interactions, the big screen was just too tempting for tiny sibling hands to disrupt the game. 

It’s also irritating to see private information, like credit card information, written several inches high, making it visible across the room.
