The difference from the Led display and Lcd monitor

The difference of the Led display and Lcd 2010-09-11 21:57 There are 2 ways of using the led , 1.using of led sigle valve, including the lights backsources Led , infrared Leds and the other one is “Led display “,Now in the chinese company  ,there are some difference of the led producing procedure between the international company when they produce the led materials .Led display is made by the led .It use the lower voltage driver to scann ,it has some adavantage such as “lower power , low cost, high brigtness ,less fault ,big viewing angle,big distance of view etc . Compare with the Led display and Lcd montior ,there are some advantage here ,for example ,the brightness ,power cost and refresh rates are all more better then the lcd monitor.  Normally  LED and LCD power consumption ratio is about 10:1, and higher refresh rate makes the LED have better performance in the video .it can provide the perspective of 160 ° wide and  can play the text and characters ,numbers ,color pictures and video informations ;also can broadcaste  the signal of TV ,Video ,VCD ,DVD etc . Pieces of display can also broadcast networking The response speed  of a Organic LED display is about 1000 times more than the Lcd monitor .It also can be watched under the stronger brigtness .Use the Led technology ,you even can make  a more brightness and ,thinner  led display under the temperature -40 degree . Lcd is a crystal screen ,it  is including the TFT ,UFB,TFD ,STN and other types of liquid crystal Screen . The laptops Lcd monitoer normally use the TFT .TFT  the full name is ” Thin Film Transistor “which is an active matrix type liquid crystal display, ,it can set special fluorescent tubes on the back .It  can take the initiative on the screen to control each pixel independently.This is also called “active matrix TFT . this can be greatly improved the reaction time.It’s about 80 milliseconds and the reaction time of  STN is about 200 milliseconds! Compared with STN, TFT has excellent color saturation, reducing power and higher contrast, under the sun still can watch very clearly, but the drawback is more power and higher cost. Simply said ,the LCD and LED are 2 different display technology .Lcd is made by the composed of liquid crystal displays But led display is made by the led  .Compared to the Lcd , LED display have more advantageson  the brightness ,view angle ,and refresh rates .

Mobile Phone Screen technology: Super AMOLED display

Over the past three years from the introduction of the iPhoneto thelatest mobile operating system Windows Phone 7, mobile phones have been getting rapidly more sophisticated and have been transformed with the introduction of applications. However, though it is the software – apps and operating systems – that have dominated headlines, this functionality would not be possible without supporting developments in hardware. For example all those HTC Desires and iPhone 4s would be almost inoperable without the help of speedy 1GHZ Snapdragon processors. Similarly, web browsing and photo viewing would be futile without the support of robust mobile phone screens.   Indeed Samsung has been pulling customers away from smartphone titans HTC and Apple with the astonishing super AMOLED screens on its top-end mobile phones like the Omnia 7 and Galaxy S. But what makes Samsung’s screens so super? Read on an understanding of how mobile phone screens function and what makes a super AMOLED display stand out.   TFT LCD screens For some time the industry average for touch screen mobile phones was TFT LCD – thin film transistor liquid crystal display. TFT LCDs were a significant advance over previous cathode ray tube displays (CRTs) for being more lightweight, reliable and cheaper.   However, liquid crystals are unable to directly emit light and so TFT LCD screens also require a backlight. So a TFT LCD screen has several layers – back light, liquid crystal, touch screen sensors and outer window. These extra layers blunt the image and colour.   AMOLED screens The next progressions from TFT LCD displays are AMOLED screens (active-matrix organic light-emitting diode screen). An OLED screen is also specific type of thin film display. However unlike a TFT LCD it is able to generate its own light using organic compounds. This makes an OLED display thinner than a TFT LCD as it does away with the back light layer. The ‘active matrix’ – the AM of AMOLED – is the technology that orders the display’s pixels allowing it to display finer images with stronger colour.   Importantly for smartphones with their wide range of battery-sucking features, an AMOLED screen uses less power than an LCD screen.   Next generation AMOLED screens Samsung is the most high profile manufacturer to take AMOLED screens a step further by incorporating touch screen sensors directly into the display screen. These ‘super AMOLED’ displays operate as an AMOLED screen does but without the need for an additional layer of capacitive touch screen sensors.   Though the name isn’t quite as evocative as the iPhone 4‘s “Retina Display”, Samsung’s super AMOLED screens have certainly given devices like the Samsung Omnia 7 a competitive edge.  Reviewing it, the display resolution is superb. It’s especially well suited to the Windows Phone 7 interface –Microsoft’s vivid menus and windows pop with rich colour. The brightness levels are also up on the average, which gives solid black and a crisp contrast ratio.  By reducing the number of layers and the spaces between them, the screen is also more usable in direct sunlight than most OLED mobile phone screens and has a wider viewing angle.   Screens of the Future For now the super AMOLED screen is at the highest end of mobile phone screen technology. But how will screens develop in the future? Manufacturers are currently working on solutions for common complaints, such as widening viewing angles and the strength of colours in direct sunlight. This will be even more important as tablet devices increase in uptake and users come to expect more visual functionality of their phones, tablets and e-readers.

Extended display identification data

Background The channel for transmitting the EDID from the display to the graphics card is usually the IC bus, defined in DDC2B (DDC1 used a different serial format which never gained popularity). Before DDC and EDID were defined, there was no standard way for a graphics card to know to what kind of display device it was connected. Some VGA connectors in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized. The EDID is often stored in the monitor in a memory device called a serial PROM (programmable read-only memory) or EEPROM (electrically erasable PROM) and is accessible via the IC bus at address 0×50. Many software packages can read and display the EDID information, such as read-edid and PowerStrip for Microsoft Windows and XFree86 (which will output the EDID to the log if verbose logging is on (startx — -logverbose 6)) for Linux and BSD unix. On Linux you can also see the raw EDID in hexadecimal format if you run “xrandr –verbose”. Mac OS X natively reads EDID information (see /var/log/system.log or hold down Cmd-V on startup) and programs such as SwitchResX or DisplayConfigX can display the information as well as use it to define custom resolutions. Enhanced EDID (E-EDID) Enhanced EDID was introduced at the same time as E-DDC; it introduced EDID structure version 1.3 which supports multiple extensions blocks and deprecated EDID version 2.0 structure (although it can be supported as an extension). Data fields for preferred timing, range limits, monitor name are required in E-EDID. E-EDID also supports dual GTF timings and aspect ratio change[clarification needed]. With the use of extensions, E-EDID string can be lengthened up to 32 KBytes. EDID Extensions assigned by VESA Timing Extension (00h) Additional Timing Data Block (CEA EDID Timing Extension) (02h) Video Timing Block Extension (VTB-EXT) (10h) EDID 2.0 Extension (20h) Display Information Extension (DI-EXT) (40h) Localized String Extension (LS-EXT) (50h) Microdisplay Interface Extension (MI-EXT) (60h) Display Transfer Characteristics Data Block (DTCDB) (A7h, AFh, BFh) Block Map (F0h) Display Device Data Block (DDDB) (FFh) Extension defined by monitor manufacturer (FFh): According to LS-EXT, actual contents varies from manufacturer. However, the value is later used by DDDB. Revision history August 1994, DDC standard version 1 – EDID v1.0 structure. April 1996, EDID standard version 2 – EDID v1.1 structure. 1997, EDID standard version 3 – EDID structures v1.2 and v2.0 February 2000, E-EDID Standard Release A, v1.0 – EDID structure v1.3, EDID structure v2.0 deprecated September 2006 – E-EDID Standard Release A, v2.0 – EDID structure v1.4 Limitations Some graphics card drivers have historically coped poorly with the EDID, using only its standard timing descriptors rather than its Detailed Timing Descriptors (DTDs). Even in cases where the DTDs were read, the drivers are/were still often limited by the standard timing descriptor limitation that the horizontal/vertical resolutions must be evenly divisible by 8. This means that many graphics cards cannot express the native resolutions of the most common wide screen flat panel displays and liquid crystal display televisions. The number of vertical pixels is calculated from the horizontal resolution and the selected aspect ratio. To be fully expressible, the size of wide screen display must thus be a multiple of 169 pixels. For 1366768 pixel Wide XGA panels the nearest resolution expressible in the EDID standard timing descriptor syntax is 1360765 pixels, typically leading to 3 pixel thin black bars. Specifying 1368 pixels as the screen width would yield an unnatural screen height of 769.5 pixels. Many Wide XGA panels do not advertise their native resolution in the standard timing descriptors, instead offering only a resolution of 1280768. Some panels advertise a resolution only slightly smaller than the native, such as 1360765. For these panels to be able to show a pixel perfect image, the EDID data must be ignored by the display driver or the driver must correctly interpret the DTD and be able to resolve resolutions whose size is not divisible by 8. Special programs are available to override the standard timing descriptors from EDID data; PowerStrip for Microsoft Windows and SwitchResX for Mac OS X. Even this is not always possible however, as some vendors’ graphics drivers (notably those of Intel) require specific registry hacks to implement custom resolutions, which can make it very difficult to use the screen’s native resolution.

Unfolding the display technology innovations: from LCD TC to SED TV

You would have often come across the terms ‘LED’ and/or ‘LCD’ while buying or speaking about the TVs, computer monitors or other display devices. The LED is the short form of the light emitting diode, which is an electronic component that is used in the electronic instruments for displaying light. The LCD refers to the Liquid Colour Display, which is a technology in which the use is made of the liquid crystals to provide display of different colours. The LCD TV was an improvement over the old cathode ray tube (CRT) based TV. A LCD TV was more practical and provided and better viewing quality than the CRT based TV. These are not thick and bulky, like the old CRT TVs but, on the contrary, these are slimmer and flatter than the traditional ones. These make use of the cold cathode fluorescent lamps for backlighting purposes. This is where the main difference between the LCD and the LED TV lies. The LED lighting from behind the screen is done, not with the fluorescent bulbs but with the light emitting diodes. This small technological change has redefined the viewing quality of the TVs which have since then become flat panel, use less of power and offer better contrast ratios. The more recent technological change has been to use the SED technology, or the surface conduction electron-emitter display technology. These imbibe the qualities of the CRT TVs and the LCD displays. So, these offer you wide display angles, higher contrast ratios, wider viewing angles of the CRT TVs and thin and slim features of the LCD TV. Major electronic companies of the world have been producing the LED displays for different uses for a long time now. In fact, the popularity of the LED lighting displays made by top companies like Sony, Samsung, Toshiba and others has risen considerably. The total number of LCD TVs sold in a year has now been able to breach the yearly sales figures of the CRT TVs. Another popular change has been the evolution of high definition high resolution audio-video formats. The use of high definition audio and sound quality has tremendously improved the audio and video quality. The use of special cables to connect the various devices, which support the high definition pictures and audio quality, have been able to deliver error free and undistorted quality. The high definition DVD, also called the HD DVD, stores the high resolution data and the DVD player sends these signals through the HDMI cables to the LED display networks. The innovations in the display technology and the improved functionality of the systems making use of the high definition sounds and pictures has made possible the theatre experience to come right in your homes. Aptly called the home theatre, the system make use of the HD LCD TV, HD DVD players and HDMI connecting wires, apart from other devices like the speakers, amplifiers, etc.

LCD screen does not flicker, can reduce the display of the eye injury, eye fatigue is not easy

Body thin, space-savingAnd more cumbersome than CRT monitors, LCD monitors as long as the former one-third of the space.Power, does not produce heatIt belongs to low-power products that can be completely heat (some of the major electricity and heat present in the backlight lamp or LED), and CRT monitors, because imaging technology inevitably leads to high temperature.No radiation, the benefits of healthLCD completely without radiation, which for all people who work at the computer is a boon.Soft focus pictures do not hurtIs different from CRT technology, LCD screen does not flicker, can reduce the display of the eye injury, eye fatigue is not easy. But from another angle LCD digital interface is not very common, far to the applications. In theory, the liquid crystal display is a pure digital device, the host computer should also be used to connect digital interface, digital interface, the advantages of self-evident. First, the module can reduce the signal loss during the conversion process and interference; reduce the conversion of the corresponding circuits and components; second clock frequency is not required, the adjustment vector.LCD response time is a special target. LCD monitor10.4 Inch Touch Screen LCD Monitor response time refers to the input signal of each pixel response rate, response time, shows the campaign does not produce images when the screen trailing phenomenon. This is playing games, watching video when fast action is important. Fast enough response time to ensure the continuity of the screen. Present, there is a general liquid crystal display, response time is quite different than before the break, usually around 40ms. But as the technology development of LCD and CRT increasing this gap is gradually being up on a liquid crystal display response time has been reduced to 5ms.Judging from the shape the appearance of light and ultra-thin LCD display, compared with the conventional spherical display, its thickness, size is only half of CRT monitors (such as acer’s FP581, its thickness is less than ordinary people feel that CRT displays 1 / 5 ), greatly reducing the floor space. This question was to ask you for your display purposes. As we all know, since liquid crystal molecules are neither light, therefore, need to rely on external light source LCD auxiliary light. In general, 140 lumens per square meter is enough. Some manufacturers 10.4 Inch TFT LCD Touch Screen Monitor standards and practical standards for the parameters there is a gap. Here to explain is that some small-sized liquid crystal displays in the past were mainly used in notebook computers, two-light adjustment, so they are not very good brightness and contrast. But now the mainstream of the desktop version of the LCD display brightness can generally be up to 250 lumens to 400 lumens, has begun to move closer to the level of a CRT.
