Liquid Crystal Display
A liquid-crystal display (LCD) is a flat panel display, flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector (photography), reflector to produce images in color or monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character ...

Amharic Language
Amharic ( or ; (Amharic: ), ', ) is an Ethiopian Semitic languages, Ethiopian Semitic language, which is a subgrouping within the Semitic languages, Semitic branch of the Afroasiatic languages. It is spoken as a first language by the Amhara people, Amharas, and also serves as a lingua franca for all other populations residing in major cities and towns of Ethiopia. The language serves as the official working language of the Ethiopian federal government, and is also the official or working language of several of Regions of Ethiopia, Ethiopia's federal regions. It has over 31,800,000 mother-tongue speakers, with more than 25,100,000 second language speakers. Amharic is the most widely spoken language in Ethiopia, and the second most spoken Languages of Ethiopia, mother-tongue in Ethiopia (after Oromo language, Oromo). Amharic is also the second largest Semitic language in the world (after Arabic). Amharic is written left-to-right using a system that grew out of the Geʽez script. ...

Text Figures
Text figures (also known as non-lining, lowercase, old style, ranging, hanging, medieval, billing, or antique figures or numerals) are numerals designed with varying heights in a fashion that resembles a typical line of running text, hence the name. They are contrasted with lining figures (also called titling or modern figures), which are the same height as upper-case letters. Georgia is an example of a popular typeface that employs text figures by default. Design In text figures, the shape and positioning of the numerals vary as those of lowercase letters do. In the most common scheme, '' 0'', '' 1'', and '' 2'' are of x-height, having neither ascenders nor descenders; '' 6'' and '' 8'' have ascenders; and '' 3'', '' 4'', '' 5'', '' 7'', and '' 9'' have descenders. Other schemes exist; for example, the types cut by the Didot family of punchcutters and typographers in France between the late 18th and early 19th centuries typically had an ascending ''3'' and ''5'', a form pr ...

Telugu Language
Telugu (; , ) is a Dravidian language spoken by Telugu people predominantly living in the Indian states of Andhra Pradesh and Telangana, where it is also the official language. It is the most widely spoken member of the Dravidian language family and one of the twenty-two scheduled languages of the Republic of India. It is one of the few languages that has primary official status in more than one Indian state, alongside Hindi and Bengali. Telugu is one of six languages designated as a classical language (of India) by the Government of India. Telugu is also a linguistic minority in the states of Karnataka, Tamil Nadu, Maharashtra, Gujarat, Chhattisgarh, Orissa, West Bengal, and the union territories of Puducherry and Andaman and Nicobar Islands. It is also spoken by members of the Telugu diaspora spread across countries like United States, Australia, United Kingdom, Canada, New Zealand in the Anglosphere; Myanmar, Malaysia, South Africa, Mauritius; and the Arabian Gulf count ...

Seven-segment Display
A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. History Seven-segment representation of figures can be found in patents as early as 1903 (in ), when Carl Kinsley invented a method of telegraphically transmitting letters and numbers and having them printed on tape in a segmented format. In 1908, F. W. Wood invented an 8-segment display, which displayed the number 4 using a diagonal bar (). In 1910, a seven-segment display illuminated by incandescent bulbs was used on a power-plant boiler room signal panel. They were also used to show the dialed telephone number to operators during the transition from manual to automatic telephone dialing. They did not achieve widespread use until the advent of LEDs in the 1970 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Descender
In typography and handwriting, a descender is the portion of a letter that extends below the baseline of a font. For example, in the letter ''y'', the descender is the "tail", or that portion of the diagonal line which lies below the ''v'' created by the two lines converging. In the letter ''p'', it is the stem reaching down past the ''o''. In most fonts, descenders are reserved for lowercase characters such as ''g'', ''j'', ''q'', ''p'', ''y'', and sometimes ''f''. Some fonts, however, also use descenders for some numerals (typically ''3'', ''4'', ''5'', ''7'', and ''9''). Such numerals are called old-style numerals. (Some italic fonts, such as Computer Modern italic, put a descender on the numeral ''4'' but not on any other numerals. Such fonts are not considered old-style.) Some fonts also use descenders for the tails on a few uppercase letters such as ''J'' and ''Q''. The parts of characters that extend above the x-height of a font are called ascenders. Descenders a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typeface
A typeface (or font family) is the design of lettering that can include variations in size, weight (e.g. bold), slope (e.g. italic), width (e.g. condensed), and so on. Each of these variations of the typeface is a font. There are list of typefaces, thousands of different typefaces in existence, with new ones being developed constantly. The art and craft of designing typefaces is called ''type design''. Designers of typefaces are called ''type designers'' and are often employed by ''type foundry, type foundries''. In desktop publishing, type designers are sometimes also called ''font developers'' or ''font designers''. Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for character (symbol), characters from different scripts, e.g. Roman uppercase A looks the same as Cyrillic uppercase А and Greek uppercase alpha. There are typefaces tailored for special applications, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascender (typography)
In typography and handwriting, an ascender is the portion of a minuscule letter in a Latin-derived alphabet that extends above the mean line of a font. That is, the part of a lower-case letter that is taller than the font's x-height. Ascenders, together with descenders, increase the recognizability of words. For this reason, many situations that require high legibility such as road signs avoid using solely capital letters (i.e. all-caps). Studies made at the start of the construction of the British motorway network concluded that words with mixed-case letters were much easier to read than "all-caps" and a special font was designed for motorway signs. These then became universal across the UK. See Road signs in the United Kingdom. In many fonts intended for body text, such as Bembo and Garamond Garamond is a group of many serif typefaces, named for sixteenth-century Parisian engraver Claude Garamond, generally spelled as Garamont in his lifetime. Garamond-style typefa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Question Mark
The question mark (also known as interrogation point, query, or eroteme in journalism) is a punctuation mark that indicates an interrogative clause or phrase in many languages. History In the fifth century, Syriac Bible manuscripts used question markers, according to a 2011 theory by manuscript specialist Chip Coakley: he believes the ''zagwa elaya'' ("upper pair"), a vertical double dot over a word at the start of a sentence, indicates that the sentence is a question. From around 783, in ''Godescalc Evangelistary'', a mark described as "a lightning flash, striking from right to left" is attested. This mark is later called a . According to some paleographers, it may have indicated intonation, perhaps associated with early musical notation like neumes. Another theory, is that the "lightning flash" was originally a tilde or titlo, as in , one of many wavy or more or less slanted marks used in medieval texts for denoting things such as abbreviations, which would later become ...

Brahmi Numerals
The Brahmi numerals are a numeral system attested from the 3rd century BCE (somewhat later in the case of most of the tens). They are a non positional decimal system. They are the direct graphic ancestors of the modern Hindu–Arabic numeral system. However, they were conceptually distinct from these later systems, as they were not used as a positional system with a zero. Rather, there were separate numerals for each of the tens (10, 20, 30, etc.). There were also symbols for 100 and 1000 which were combined in ligatures with the units to signify 200, 300, 2000, 3000, etc. In computers, these ligatures are written with the Brahmi Number Joiner at U+1107F. Origins The source of the first three numerals seems clear: they are collections of 1, 2, and 3 strokes, in Ashoka's era vertical I, II, III like Roman numerals, but soon becoming horizontal like the ancient Han Chinese numerals. In the oldest inscriptions, 4 looks like a +, reminiscent of the X of neighboring , and perh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
