Difference Between LCD and LED

Various reasons are behind the every purchase by customers. So they wanted best in his/her budget. But if any consumer is going to buy Display Screen for any purpose than they got struck with the question that do they buy LED or LCD Display? So to ease out this difficulty we are presenting difference between LCD and LED.

LCD:

LCD are developed by using cold cathode fluorescent to lit up the screen. LCDs are brighter, thinner, light and energy efficient with 100-200Hz processing engines to better handle fast motion. The LCD uses liquid crystal diode (LCD) technology with front panel containing the “twisting crystals” which define LCD technology. Display’s performance can be guessed with its processing engines means more processing frequency will result into better display.

Advantages And Disadvantages:

Very first disadvantage of the LCD is that it show black spots where the back light gets blocked by LCD panels.  There are LCD with Fluorescent and coloured backlights which differ their performance on colour accuracy of display. And in coloured backlights there’s variation of RGB and White backlights. The LCD colour  accuracy is not accurate as  that of LEDs in white backlights but the competition is same inn the LCD which uses RGB backlight. The point we are going to discuss is the topmost query by customers and that is the viewing angle for display to view it clearly and sharply without black spots and LCDs are better for it as they are not much thin. Fast moving playback is even on both display and even it depends upon refresh rate and time. Consumers need to  have good refresh rates for better moving playback. You can consider both the displays  for Gaming. Its lifetime is less than of LEDs  as its back lighted by Fluorescent bulbs. Its also great in brighter environments.

LED:

LEDs are developed by light emitting diodes rather than CCFL in Liquid Crystal displays (LCD) due to which various panels are removed from it and it becomes thin and more brighter than LCDs. It stimulates the true black by dimming specific areas of the display. Its also consumes low power as compared to LCDs. Mainly it have features of both Plasma and LCD displays.

Advantages and disadvantages:

LEDs show best black levels and high contrast ratios.  LEDs show realistic colours in displays using RGB backlight colours. LEDs are more expensive than LEDs but it have latest technologies with that of LCD and Plasma features. Leds perform better for viewing from different angles as its light is coming from directly behind the screen. As discussed above fast moving playback depends upon refresh interval and time. Manufacturers recommend LCDs for gaming due to its backlighting during game play but from users prospectus both are even. The timeline of LEDs are better of about 100000 ours as its manufactured by LED lights not CFL which is used for LCDs manufacturing. Its LED light system helps to it to remain cool.

Due to its thinness ultra thin books are coming to market and added more choices to customers. So guys which one you gonna buy now?

Which is Best: AMD Processors Vs Intel Processors

Now days while Purchasing the computer there are many options available of every thing like Graphics solution, Screens and Processors and out of all of them processor is the main part of the computer which processes all the tasks running on the computer. So while purchasing the computer you should select best option for processors which suits you better. You may heard the name of two big companies which makes the processors one is Intel and other is AMD. Here we compare processors of both the companies for you to make correct decision while purchasing the computer.

  • If you are taking performance above all than Intel processors are the way to go because AMD processors are currently not being able to compete with Intel for raw speed .
  • AMD processors are capable of performing well with the quite affordable price. As Intel processors are costlier than AMD processors.
  • It is not easy to select the Processor because their are different series of processors in both the companies. In Intel, Core 2 CPU’s are still available and second series is the Sandy bridge (i series) processors which is 40% faster than its predecessors  they also come with an on-board graphics chip. So if you choose the Intel you should select the series.
  • In AMD their is Athlon II series which came into  X2, X3 and X4 varieties but the performance of these processors in not good. AMD’s Phenom II is the other series of processors from AMD which have more cache memory than the Athlon II’s , running at higher clock speed and gives the better performance.

Final Verdict

After looking at the product ranges of both the companies the question raises in our mind  that which is the best? it all depends on what you are looking for. If price is the key than AMD processors are excellent choice because intel’s processors are little more expensive. If their is no issue with money and you want the processor which performs better than you should select Intel.

What Is Corning Gorilla Glass?

Gorilla Glass is a thin and tough protective layer on devices which have big screens like those in Tablets, Smartphones, TVs and other electronic devices. It reduces the possibility of breakage of screens on devices. Gorilla Glass was developed and manufactured by Corning in 2007.

Until 2010, 20% of Mobile devices, approximately 200 million mobile handsets used this technology and around 2012 the share rose to 50%. Now most newly developed Electronic Devices with Screens have Gorilla Glass. Corning Gorilla Glass is used by more than 30 major brands and has been featured in more than 750 product models, spanning over 750 million units worldwide. There are various other types of Glasses in the market but Gorilla Glass is :

  • Damage Resistible: It gives better damage resistance against flaws from the user’s end. It reduces the risk by creating a deep compression layer on the screen’s surface which is formed by chemical processes.
  • Hard: It is quite hard and can save your screen from damage.
  • Thin: Its thinness can vary between 0.5mm- 2mm according to the need of the manufacturer.
  • Lightweight: Its weight is similar to nothing.
  • Scratch Resistant: With all the above features it also protects your screen against scratches.

Corning Gorilla Glass

After its Gorilla Glass popularity, Corning developed Gorilla Glass 2 and announced it at CES this year with several improvements. New Glass 2 is 20% thinner and it enables the development of slimmer devices with greater touch sensitivity. It is the ideal option to use this unimaginative Glass from Corning  for the manufacturers of Tablets, Smartphones and Laptops . It provides brighter images without sacrificing its quality. Most big companies like HTC, Samsung, LG, Sony, etc use this technology. Samsung Galaxy S III also has Corning Gorilla Glass 2.

Integrated Graphics vs Dedicated Video Card

Nowadays when we go to purchase a Computer or Laptop, we come across two options in choosing the graphic solutions – Integrated Graphics and Dedicated Video Card. We have tried to differentiate between them below to help you make the right choice between them while purchasing computers and laptops.

  1. Integrated Graphics consume less power and produce less heat as compared to dedicated Video Cards.
  2. Dedicated Video Cards are much costlier than Integrated Graphics. Although the Integrated Graphics solutions are not as serviceable but they are much more affordable.
  3. As the Dedicated Video Cards have their own memory and processing power, they can perform much stronger than integrated graphics systems.

Choosing the Right Solution

While building a new computer, you must keep in mind what you are looking to build it for. If you are purchasing the computer for only word processing and web browsing, then you can choose the Integrated Graphics Solution but if you want to play games or want to do Graphics related work, you can select the Dedicated Video Cards.

Difference Between SSD and HDD

Earlier the PC buyers had very little choice in the primary storage section of their PC’s, Netbooks, Laptops, Ultrabooks. But now, as the technology upgrades the new technology came called SSD (Solid state disk) which very fast as compare to the HDD (Hard disk drive). All though the SSD is expensive than HDD, but if performance and fast bootup are top consideration, and money is secondary, then SSD is the way to go. We have described SSD and HDD in detail and compared them for you.

HDD -  Hard Disk Drive

HDD - Hard Disk Drive

Hard disk Drives are first introduced in 1956. It is the traditional primary storage drives which are used by all of us. HDD basically use the magnetism to store data on rotating platter. Then Read/Write heads move on the platter to perform reading and writing operations. Typically now days laptop drives spin at either 5400 RPM (Revolutions per Minute) or 7200RPM. While the core HDD ideas are simple enough, allowing manufacturers to produce high capacity drives at very low prices. Cost HDD is only around $0.10 / GB these days. Major advantage of an HDD is that it is capable of storing lots of data cheaply.

SDD - Solid State Disk

Solid State Disk is the new technology which came in 1994. By coming of this technology to the market gives the option to the PC users from which they can choose between SSD and HDD. You all are familiar with the USB memory sticks the SSD is the oversized and more sophisticated version of the USB memory sticks. Unlike HDD there are no moving parts in SSD the data is stored in the in microchips. SSD uses NAND based flash memory which is non volatile in nature in which if we turn off the disk the data stored in it does not vanished.  During the early days of SSD rumors that data stored in these drives will be lost after few years but this is not ture the data saved in these drive will be maintained well over 200 years.

SDD - Solid State Disk

SSD does not have the Read Write head instead of it these disks have embedded processor called controller which perform the Read Write operations. SSD drives generally have low capacities and high prices as compared to HDD ,SSD drives are much expensive than HDD.

Now let’s do some comparison and determine which one is better SSD or HDD.

  • Power – SSD consumes less power approximately 2-3watts while HDD consumes 6-7Watts which means by using SSD we can boost our battery of our laptops.
  • Capacity - Typically SSD are not larger than 256GB but HDD have more greater sizes available 500GB-1TB for notebooks.
  • Bootup Time - The booting time of the system is less while using SSD approximatly 20-25 seconds while HDD takes more time for booting.
  • Noise and Vibration - As in HDD their is a Read Write head which wile moving on the platter makes noise and spinning of platter produces vibration from this point of view SSD are better because in SSD there is not any Read Write head and platters it has processor to do read write operations which does not make noise. 
  • CostThe cost of SSD is higher  than HDD .
  • File Copy / Write Speed - Generally speed of SSD is above 200 MB/s and up to 500 MB/s for cutting edge drives which is quite more than the speed of HDD from 50 – 120MB / s.

Difference Between CPU and GPU

Rarely, people know about GPU and CPU is known by all of us and is better known as brain of computer. But what is GPU? and Difference Between them?

At older times CPU – Central Processing Unit handles all the processes and derive them to users. Than advancement came in the era of Processors and they started crunching more information at faster rate. But researchers need more speed out of the processor. So they elevated Graphical Processing from CPU to GPU – Graphics Processing Unit and this change not only increased processing speed but due integrated processing unit for Graphics betterised Graphics on our screens.

The new GPU can perform common graphics routines really fast. GPUs were originally developed to render 2D graphics but according to need it became faster and more specialized in its task. Insight64 principal analyst Nathan Brook wood described the unique capabilities of the GPU this way:

[quote]GPUs are optimized for taking huge batches of data and performing the same operation over and over very quickly, unlike PC  Microprocessors, which tend to skip all over the place.[/quote]

Coming onto architecture GPU’s consist hundreds of cores which can handle various threads at a time in respect to CPU which have only few cores with lots of cache memory that can handle a few software threads only. GPU is also efficient in cost and power aspects. GPU’s make software to run at 100x faster speed than CPU.

With more advancement now GPU’s can be used for any purpose, not just graphics or video related purposes. Nvidia  CUDA, the first true GPGPU which basically, is a way to use the GPU(s) on a video card as general-use supplemental processors. GPU-accelerated computing has now grown into a mainstream movement supported by the latest  Operating systems from Apple (with Open CL) and Microsoft (using Direct Compute). The combination of a CPU with a GPU can deliver the best value of system performance, price, and power.
