Consumer Electronics Show

The 2014 International CES was held during the week from January 7 to 10, 2014, in the Las Vegas Convention Center, Las Vegas, Nevada, United States. The first Li-Fi smartphone prototype was presented at the show. The smartphone uses SunPartner's Wysips CONNECT, a technique that converts light waves into usable energy, making the phone capable of receiving and decoding signals without drawing on its battery. The phone also has a transparent photovoltaic screen that lets light recharge the phone.

LG debuted its webOS on smartTVs and new 77-inch curved OLED Ultra HD TV. Samsung unveiled its curved TVs with two series of concave TVs.

ProtectCELL showcased its comprehensive mobile protection plans for all major devices, including the iPhone 5S and 5C, iPad Air, iPad Mini 2 and Galaxy S4. With demonstrations such as blending a Blackberry, ProtectCELL proves they will cover all damages.

The AMD presentation mentioned (among others) – the Kaveri CPU of the Steamroller architecture, Heterogenous System Architecture (HSA) lineup and the intention to build upon that, immersive experience, Mantle and AMD TrueAudio.

In the Intel keynote presentation, its CEO talked about three areas in which technology can improve: living, working, and playing. He also presented Intel Edison, a SoC of the SD card format.

Pebble announced the Pebble Steel smartwatch, which has a thin body, tactile metal buttons, and Corning Gorilla Glass.

Laser diodes were unveiled at the show that are going to be used for high-beam headlights in Audi vehicles. The high beams will be lasers, though the low beams will be light-emitting diodes. The car maker says that their high beams have a 500-meter range, which is roughly twice the distance of LED high beams. Lasers are expensive though. Lasers are smaller, brighter and more energy efficient than LED headlamps. Their laser headlamps use less than half the energy of LEDs. Laser diodes can emit 170 lumens per watt, while LEDs generate only 100 lumens. Lasers are sensitive to heat but that has not stopped their production for vehicles. Laser technology is not as advanced compared with LEDs, which have been around for decades.

The 2015 International CES was held during the week January 6–9, 2015, in the Las Vegas Convention Center, Las Vegas, Nevada, United States. The 2015 CES was reportedly the largest in its history, with 3,600 exhibitors and 170,000 professional/industry attendees.

The Internet of Things, impacting all other industries, has been recognized as the buzzword of the CES edition 2015. The interoperability between the connected objects, with changing and multiple alliances, and if some of the products are meeting real needs or are only gadgets, are the main issues detected.

Wearables, involving health trackers, as the smartwatch, are getting more specialized and design is getting better, fitting better to the mass market.

Robots and home automation devices were omnipresent. Major announcements included a realistic robotic hostess by Toshiba, autonomous telepresence bots by Intel and iRobot, a developer program for Google's Nest, Samsung's SmartThings hub for connecting devices, and a number of Apple HomeKit brand home automation products, though the company stopped officially exhibiting at CES back in 1992.

Every auto maker who had any kind of presence at the show offered a glimpse into some kind of intelligent, driver-free technology, from parking to advanced object recognition. Audi showed four generations of driver-assist automated car tech.

Unlike 3D TV, which has disappeared from the announcements at the CES 2015, 3D visualization is now more specialized and target the B2B environment, from modelization to immersive glasses and helmets for architects, healthcare specialists or gamers.

3D printing continues to grow and vendors make meaningful improvements in their products, while making them easier to use and less expensive.

Most TV manufacturers announced 4K TV models :

Samsung released several new 4K televisions including a massive 105-inch set that bends on command.
LG unveiled the LG G Flex 2, second generation of its curved Android smartphone, and a new lineup of 4K televisions including one bending TV as well.
Sharp showed off its Ultra HD 8K television expected for late 2015 
Sony showed off a 4K action camera which automatically detects the best parts of your footage and picks out the best clips for you.
Toyota revealed it plans to release its fuel cell patents to the public royalty free.

The 2017 CES was held January 5–8, 2017, in Las Vegas. Even with tight security at the show, two prototype Razer triple-screen gaming laptops were stolen during the show. Min-Liang Tan, co-founder and chief executive officer of Razer, said that the company is treating the case as "industrial espionage". A Razer spokesperson said they were offering $25,000 for any "original information leading to the identification, arrest and conviction" of anyone who was involved with the crime.

Companies offering wireless charging solutions were popular at CES in 2018. Many vendors had shown off contact-based charging pads. Others demonstrated products delivering power at a distance. Some vendors exhibited near-field products (Energous, Powercast) and mid-field products (Ossia, uBeam). Wi-Charge has demonstrated first far-field charging product.
