Motorola Razr (2020)
The Motorola Razr (stylized motorola razr, also known as ''RAZR 2019'' or ''RAZR 2020'') is an Android foldable smartphone produced by Motorola Mobility. Unveiled on November 14, 2019, it was released on February 6, 2020 reviving the Razr line and designed to be reminiscent of the original Motorola Razr V3. It features a clamshell horizontally foldable screen that is fully touchscreen and rollable. An updated version of the phone, Motorola Razr 5G, was released on September 15, 2020. Motorola introduced a successor, Motorola Razr (2022), in August 2022. Specifications The Razr is inspired heavily by the original feature phone line of the same name, and uses a clamshell design to conceal a 6.2-inch 21:9 OLED display. The device's exterior features a secondary 2.7-inch "Quick View" display to access selected features (such as notifications) when the device is closed. The screen is protected by a stainless-steel frame, is "scuff resistant", and has no visible crease at its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola Mobility
Motorola Mobility LLC, marketing as Motorola, is an American consumer electronics manufacturer primarily producing smartphones and other mobile devices running Android (operating system), Android. It is a wholly owned subsidiary of the Chinese technology giant Lenovo. Motorola is headquartered at Merchandise Mart in Chicago, Illinois. Motorola Mobility was formed on January 4, 2011, after a split of the original Motorola into two separate companies, with Motorola Mobility assuming the company's consumer-oriented product lines, including its mobile phone business, as well as its cable modems and pay television set-top boxes. In May 2012, Google acquired Motorola Mobility for US$12.5 billion; the main intent of the purchase was to gain Motorola Mobility's patent portfolio, in order to protect other Android vendors from litigation. Shortly after the purchase, Google sold Motorola Mobility's cable modem and set-top box business to Arris Group, and products increasingly focused on entr ...

Pixel Density
Pixels per inch (ppi) and pixels per centimetre (ppcm or pixels/cm) are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner. Horizontal and vertical density are usually the same, as most devices have square pixels, but differ on devices that have non-square pixels. Pixel density is not the same as where the former describes the amount of detail on a physical surface or device, the latter describes the amount of pixel information regardless of its scale. Considered in another way, a pixel has no inherent size or unit (a pixel is actually a sample), but when it is printed, displayed, or scanned, then the pixel has both a physical size (dimension) and a pixel density (ppi). Basic principles Since most digital hardware devices use dots or pixels, the size of the media (in inches) and the number of pixels (or dots) are directly related by the 'pixels per inch ...

Motorola Razr (2022)
The Motorola Razr (pronounced like "razor"), currently stylized ''motorola razr'', is a brand of mobile phones manufactured by Motorola Mobility (previously Motorola, now a division of Lenovo), currently consisting of foldable clamshell smartphones. The Razr name was introduced with the V3 model (then styled RAZR, also MOTORAZR) in 2004, which became extremely popular. The line was succeeded by the Motorola Razr2 flip phones in 2007. The Razr later evolved into a line of non-clamshell devices in 2011, Droid Razr (known simply as the "Motorola RAZR" on non-Verizon networks), bearing design similarities to the originals. Razr was revived again in 2019, this time evolving into a line of all-screen clamshell foldables that continues to this day. Original Razr line The Razr V3 was introduced in 2004 and became wildly popular. Motorola released several upgraded versions, including the Razr V3x in 2005 (which featured 3G connectivity), the Razr V3i, and the Razr v3xx in 2006, ...

Flexible Display
A flexible display or rollable display is an electronic visual display which is flexible in nature, as opposed to the traditional Flat panel display, flat screen displays used in most electronic devices. In recent years there has been a growing interest from numerous consumer electronics manufacturers to apply this display technology in e-readers, mobile phones and other consumer electronics. Such screens can be rolled up like a scroll without the image or text being distorted. Technologies involved in building a rollable display include electronic ink, Gyricon, Organic LCD, and Organic light-emitting diode, OLED. Electronic paper displays which can be rolled up have been developed by E Ink Corporation, E Ink. At Consumer Electronics Show, CES 2006, Philips showed a rollable display prototype, with a screen capable of retaining an image for several months without electricity. In 2007, Philips launched a 5-inch, 320 x 240-pixel rollable display based on E Ink’s Elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touchscreen
A touchscreen (or touch screen) is a type of electronic visual display, display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device. Touchscreens are commonly found in smartphones, tablet computer, tablets, laptops, and other electronic devices. The display is often an Liquid-crystal display, LCD, AMOLED or OLED display. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special Stylus (computing), stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, Zooming user interface, zooming to inc ...

Foldable Smartphone
A foldable smartphone (also known as a foldable phone or simply foldable) is a smartphone with a folding Form factor (mobile phones), form factor. While the foldable design has been incorporated before in clamshell design, clamshell (or "flip phone") phones, the current term "foldable" refer to a newer style with flexible display, flexible displays, although some variants of the concept use Dual-touchscreen, multiple touchscreen panels on a hinge. Concepts of such devices date back as early as Nokia's "Morph" concept in 2008, and a concept presented by Samsung Electronics in 2013 (as part of a larger set of concepts utilizing flexible OLED displays), while the first commercially available folding smartphones with OLED displays began to emerge in November 2018. Some devices may fold out on a vertical axis to into a wider, tablet computer, tablet-like form, but are still usable in a smaller, folded state; the display may either wrap around to the back of the device when folded (as w ...

Wi-Fi
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs Ultra high frequency, UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars.
