Touch Screen Display Technology

Touch screen display technologies are a prominent feature on modern day electronic gadgets and devices and have revolutionized the way communicate our gadgets. Since the advent of mobile phones, man has been able to bridge the communication gap previously existing in the time past. One of the older methods of communication simply involved sending parcels overseas. These parcels were conveyed using ships, and you’d have to wait for some months for your package to reach its destination and probably the same waiting time to get a response.

Modern technology has made it possible to communicate in real-time because technology saves considerable time and resources. Today, touch screen display technologies are featured on computers, smartphones, game consoles and many other electronic devices. Previously, we had to communicate with our computers using input devices such as the mouse, keyboard, and other input devices. Presently, we now use our fingers or the Stylus to communicate with computers, tablets and smartphones through the icons on their screen or display.

How touch screen display technologies became a prominent feature

Gadgets with touch screen displays are making the rounds in the tech market. These Touchscreen devices are very popular, smart, and possess highly sophisticated technologies that make it easy to control, program and manipulate them.

In the 80s, E.A Johnson gave an insight on the use of touch screen display technologies through his article and how it could be applied in air traffic control. He provided illustrations using diagrams on how Touch screen display technology could be used for the overall benefit of the aviation sector. However, Bent Stumpe and Frank bent, who were engineers from CERN developed the world’s first transparent touch screen. This development took place at CERN during the early 70’s, and ever since then, various touch screen display technologies have been introduced and have been improved upon, giving us the ability to control efficiently and manipulate these highly sophisticated, electronic devices such as smartphones, tablets, and computers.

Dual SIM phones

Ever since the introduction of the Subscriber identification module (SIM) in the early 90’s, mobile network operators were able to authenticate subscribers before granting them access to their network, thus improving the level of security as well as ensuring that only authorized subscribers had access to their networks. Most mobile phones were One-SIM devices and these devices served their subscribers well because things were relatively simple as at that time. But as time went on, mobile networks became unstable and congested due to over subscriptions and lack of proper maintenance, and this problem sometimes led to network downtime. Also, the high cost of calling subscribers on other networks wasn’t fair, so the subscribers had to find other ways of reducing cost.

One of the ways subscribers used to overcome these problems, initially, was by purchasing more mobile phones, but then these cost saving strategies came with their attendant problems.  The high cost of maintenance as well as the problems associated with carrying mobile phones (extra weight). The introduction of Dual SIM phones to a great extent mitigated the problems associated with using one SIM mobile phones. The first dual-SIM phone was developed by Benefon Twin and was released in the year 2000. Ever since then, many Smartphone manufacturers have continued to develop the dual SIM technology, which is still very relevant today.

CDMA and GSM systems

The Code Division Multiple Access (CDMA) and the Global System for Mobile communication (GSM) are the two major standards in the mobile phone industry. The 3G variant of these systems include the CDMA 2000 and the Universal Mobile Telecommunication Systems (UMTS), and this technology gave subscribers superfast access to the internet. The 3G network allowed for live video content streaming and video calls and this technology revolutionized the way we see and communicate with friends and family across the globe in real time. Currently, the 3G, 3.5, 3.75 networks are being replaced by 4G, which takes super fast communication to a whole new level.

The Major difference between CDMA and GSM systems hinges on the coverage area, voice data conversion as well as speed in data transfer. North America and Asian countries mainly use CDMA phones and technologies, but the world at large mostly uses GSM technology. Although most smartphones now come with technologies that make them compatible with CDMA and GSM, CDMA is currently being relegated for GSM and might soon be phased out in the nearest future.

QWERTY Messaging Phones

The introduction of half QWERTY keyboard in phones brought about the much-needed improvement in text messaging. QWERTY is the first six letters on a Keyboard, and It is the main layout for the typewriter. The QWERTY keyboard was developed by Christopher Latham Sholes in 1873 for the Sholes and Glidden typewriter. The QWERTY keyboard layout was designed to enable typist work faster and efficiently. The half QWERTY keyboard was introduced on smartphones in the late 90s and early 2000s, currently, they have been largely replaced by touchscreen virtual keyboards.

Conclusion

The introduction of Touch Screen display technologies has brought about the much need improvements in smart devices. It’s easy to operate and requires less effort to input commands. This technology has been applied in almost every facet of human endeavor. The Swipe typing technology is out of this world and has made life a lot easier, as it allows you to type efficiently using a single hand to swipe your virtual keyboard. No doubt, touch screen display technology is here to stay and will continue to remain relevant for a long time to come.
