Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.
Battery type - A battery charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.
A Lithium Ion (Li-Ion) battery is a rechargeable battery with twice the energy capacity of a Nickel-Cadmium battery and greater stability and safety.
The mAh acronym stands for Ampere-hour.
This is a unit of electric charge, and is frequently used in measurements of electrochemical systems such as batteries.
Typical battery capacities include 1500mAh and 1300mAh.
Phonebook- A directory containing an alphabetical list of telephone subscribers and their telephone numbers. Mobile phones are equipped with a quite detailed phonebook. The available information fields usually cover all the customary PIM requirements. Most of the times users can even add custom fields when the default options are insufficient.
Computer synchronization with a PIM application is quite important and most recent mobile phones offer synchronization with Microsoft Outlook or through a proprietary sync application.
Whenever possible we will try and list the contact capacity for each mobile phone in our database as accurately as possible.
Bear in mind that the number of entry fields listed concerns only the handset memory, SIM cards will usually offer an additional capacity of about 200-250 contacts.
Call records- Otherwise it is known as Calls Log. It usually includes a log of all recently dialed, received and missed calls. The Calls Log is usually stored in the phoneâ€™s memory and is erased when the SIM card is changed.
Handwriting recognition- The ability of a device or software program to analyze the shape of cursive or printed handwriting drawn on a touchscreen and then translate it into letters, words, numbers, and punctuation marks.
Most devices that have touchscreens have built-in handwriting recognition capability. Input is best done using a stylus.
It should be noted that only devices using resistive type of touchscreen readily allows for input with various objects. The capacitive touchscreen devices can accept only human finger input.
Resistive touchscreen- A resistive touch screen consists of a touch layer placed on top of a standard display. The touch layer normally includes two transparent electrical layers separated by a small gap. Resistive touchscreens operate by sensing direct pressure applied by the user. It can be activated by pressing it not only with a finger but also with a stylus (unlike the competing capacitive technology).
Pressing the displayâ€™s surface causes the two separate layers to come into contact, which creates an electrical connection that can be sensed and located.
Capacitive Touchscreen- Capacitive touch sensors are used either as buttons or on touchscreens. They work by sensing the electrical properties of the human body instead of pressure and generally they donâ€™t work with a stylus so they donâ€™t allow handwriting recognition. However, capacitive touchscreens feel more sensitive than their resistive counterparts.
Capacitive touch screens are also considered more durable than resistive touch screens.
AMOLED display (Active-matrix organic light-emitting diode)
AMOLED is an emerging display technology used in portable devices like mobile phones. Active-matrix OLED displays provide the same performance as their passive-matrix OLED counterparts, but they consume significantly less power.
This advantage makes active-matrix OLEDs well suited for portable electronics where battery power consumption is critical.
OLED (Organic Light-Emitting Diode)
A display technology that consists of small dots of organic polymer which emit light when charged with electricity.
OLED displays have several advantages over the LCDs. They are thinner, lighter, brighter, need less power, have better viewing angles, contrast and response time for video and animation. OLEDs are also cheaper and easier to manufacture.
On the other hand, LCDs offer better legibility in bright ambient light.
TFD (Thin Film Diode)
TFD is a kind of Liquid crystal display (LCD) technology. It is an active-matrix technology which means that a diode is situated next to each pixel making it possible for the pixels to be turned on and off individually. This allows a quicker response time and more contrast than passive-matrix technologies.
TFD takes the excellent picture quality and the fast response of TFT displays and combines them with the low power consumption and cost of the STN ones.
TFT (Thin Film Transistor)
TFT is one of the best Liquid Cristal Display technologies in terms of image quality and response time. However, it also consumes more power and is more expensive.
TFT, like TFD, is an active-matrix technology. This means a transistor is located next to each pixel, allowing it to be turned on and off individually. This ensures faster response time and greater contrast.
Mobile Browser- A piece of software that allows the user to access Internet sites. Web browsers on budget handset may be capable of viewing only websites specially made for mobile devices. The most advanced devices currently have web browsers with full Flash support that allows them to play even embedded Flash video.
Most current mobile handsets are equipped with browsers capable to view common websites (those intended for a desktop browser).
Java technology â€“ Often stands for â€œJava MEâ€ (the new name of J2ME, Java 2 Platform, Micro Edition). Java ME is a platform for applications running on mobile phones. These, mainly small, applications (e.g. games) can be downloaded from the Internet directly to the mobile phone using its built-in web-browser.
Loudspeaker Mobile - The loudspeaker is a small sound driver fitted within a mobile phone, or other communication device, that is used to produce sound. Traditionally, loudspeaker on mobile phones is used to produce sound alerts for events such as incoming calls, incoming messages and alarms also.
Loudspeakers are also used to reproduce voice calls out loud, thus allowing users to deal with calls hands-free or even have conference calls with others in the same room (that use of the mobile phone is called a speakerphone, which is not to be confused with a loudspeaker).
Memory Card slot
Memory Card slot- A special slot for inserting a memory card. Memory cards allow you to expand the phoneâ€™s built-in memory (or in the past these slots have been used to add some missing features such as WI-Fi connectivity). Memory cards have different capacities and are used to store and transfer files between compatible devices. Memory card slots can have various supported memory card capacities. Depending on the device, card slots can support capacities of up to 2, 4, 8, 16 or even the yet unavailable 32GB.
Mobile Screen Protection
Mobile Screen Protection- As touchscreen mobile displays are day by day growing larger in recent years, the need for enhanced scratch resistance and protection of the mobile screens created the demand for usage of screen covers of increased resistance including chemically hardened glass.
Additionally, manufacturers started applying oleo phobic coating on top of its screens in order to make finger smudges less of an issue.
Corningâ€™s Gorilla Glass is a popular brand of hardened glass used for high-end mobile phone handset in the mobile industry.
