Mobile phones are the biggest invention in the world so far and day by day this invention is growing, all companies in the world are competing against each other by providing us new and more developed and innovative products. But today we will talk about the display of mobile phones that how they display get evolved over the period of time.

Evolution of mobile displays

Motorola was the first company that introduced cell phones in 1984 named DynaTAC8000X but these devices did not have a screen until 1992. The company developed the screen in 1992 and that was a simple black and white passive matrix screen. The screen used a matrix of rows and columns and in the late 90s, the developers realized that matrix had enough potential to run games like snake and memory.

By 2001, people get bored with the same black and white display and in 2001, the cell phones evolved a step further when Nokia launched the first monochromatic display phone named Nokia 8250. This phone did not have a large array of colors, but it did have the ability to change the background color from grey to vibrant blue which was very appealing and people liked this mobile phone because of this blue screen.

Now in the same year, Sony Ericcson took a step forward and launched the first 256 palettes color phone named Sony Ericcson T68m and from here actually, the era of the color display has started with a bang. Also in 2002, the company added camera capabilities in this phone to take proper advantage of color display and people liked it very much.

Now in 2003, companies started to get more innovative and they started to develop flip phones which had multi displays just like Samsung launched Samsung S300 which had a small external screen for the message and call notification and a main internal screen for composing messaged and playing games.

Evolution of touchscreen

Touchscreens till now have two types one is a resistive touch screen and the other is a capacitive touch screen. The resistive touch screen was the first developed touch screen, where people could enjoy the touch screen through a stylus or through their nails, these displays had very low resolution as compared to capacitive touch screens. IBM Simon was the first resistive touchscreen phone, this phone was also the first smart phone.

Now here we come capacitive touch screen display and this display considered as the best touch screen display because of the touch response, that was top-notch, in this, there was no need of stylus, the display was very much responsive and it responses our skin which was considered as the best innovation in smartphones department. The first phone with the capacitive display was LG Prada which was introduced in 2006.

The launch of the iPhone in 2007 marked the dawn of a new age of cell phones and cell phone screens. It was considered the first smartphone, the first phone with an operating system, and the first with an advanced, more responsive touchscreen. Its video graphics array (VGA) display, a type of active matrix display, had far greater resolution than earlier phones. This phone had 16 million colors display which had 165 PPI and this was considered as the best display of that era because the phone had a capacitive touch but it also had a better display which gives good resolution and colors.

Today’s smartphones

Currently, there are six main display types used in mobile phones: TFT LCD, IPS-LCD, OLED, AMOLED, and Super AMOLED.

Let’s start with LCDs. TFT LCD displays are considered the most common. They deliver quality images and higher resolutions. IPS LCDs, which are mainly found in higher-end smartphones, offer improved battery life and deliver wider viewing angles. These types of displays are often found in iPhones, but by Apple’s proprietary names, “Retina,” or “Super Retina.”

OLEDs are considered an up-and-coming display technology – they don’t require any backlighting to display pixels. Fundamentally, each pixel emits it own light, allowing for darker blacks and brighter whites. AMOLEDs combine a TFT display with an OLED display for energy savings, while Super AMOLED displays deliver even brighter screens and more power savings.

And here IPS LCD and AMOLED are the main screens which companies are using both of the displays have their own advantage. IPS LCD display gives us clear and real color phones like iPhone, HTC and Huawei uses this display technology also the life of these displays considered as longer the AMOLED displays and they also use less energy than AMOLED display. And yes the cost of these displays is also cheaper than AMOLED displays. First mobile phone with IPS LCD display is iPhone 4

Let’s move to the AMOLED displays, most high-end devices use this display, because of the saturation and brightness are at higher side in this display, this display is very eye-catching and people like the colors of this display also the screen refresh rate is faster in this display as compare to IP LCD display. The first phone with AMOLED display is Nokia N85

Today all phones are coming with high resolutions like HD, UHD, 4K which gives resolutions like 1080×2400 pixels which give whooping PPI up to 500. Till date highest display resolution phone ever made is Sony xperia XZ premium which is having IPS LCD display which gives a resolution of 3840×2160 pixels and PPI of 807.

Bezel-less world

Now again companies started to move further, by giving us a new name bezel-less smartphones. The bezel-less smartphone is one which has minimal bezels(non-screen parts on the front) and because of this discovery companies started to develop bezel-less smartphones with big screens like 6 inches or 6.6 inches display which covers almost 80 to 90% screen to body ratio area and also this innovation was well admired by the whole world because it gave beautiful look to the cell phones and made it look high tech. First bezel-less phone Aquos Crystal which was introduced in August 2014.

Future of mobile displays

Micro LED display

The future is to provide more high-resolution displays with new technology namely micro-LED display or also known as MLED display. As the name suggests, MicroLED is made of millions of micro, well, LEDs. Tinier versions of what’s in your current LCD TV, or newer flashlights, light bulbs, and what myriad other devices use to create light. This display would have higher brightness and provides more stability than AMOLED or IPS LCD display also this display would consume less energy than both of the current displays because of its inorganic nature. Samsung, LG, TCL, SONY is working on this display also Samsung has just developed a staggering 292 inches micro-LED display. This display is thinner than AMOLED display and also this display is lighter than AMOLED display.

Real Dual screen phone

Yes, this is the next future. Every company in the world is focusing on this now to provide dual display in the phone which means display in front and display in back as well. ZTE Nubia X which was released in October 2018 was the first real dual-screen phone which performs exceptionally great. The phone consists of two screens 6.2 inches 4k screen in the front and 5.1 inched Full HD screen in the back panel of the phone. You can use this phone holding anyway whether you holding through the front side or you holding through the backside. And yes this is the future.
