Microsoft is trying to get more shares of the market from Nintendo and Sony by lower the price of the Xbox to $299 from $349.

Sony wants to turn its PlayStation to profit this year and is not likely to follow and the Nintendo Wii can not be delivered fast enough.

Keep on lower the price will not make the previous buyers happy but Microsoft need to get in their product in the market.

The price is not officially out yet but if you planning to buy a Xbox wait for a few weeks it will soon be lower.

LCD technology

It was in the closing decades of the 20th century that the large screen television technologies began to develop and with the progress of time and the introduction of new technological innovations, one could see the emergence of flat screen televisions. There were several different technological tools which were used in the formation of these flat screen devices, the foremost among them being the LCD technology. Primitive technologies like the CRT or the use of cathode ray tubes moved into oblivion as the flat screen techniques took centre stage and at present is the prevalent form used in the manufacture of television sets. The LCD or the liquid crystal technique is dependent on the pixels on the LCD which are again comprised of certain constituent factors. These include two glass plates with molecules, two polarizing filters and the liquid crystal molecules.

There are also different kinds of LCD display technologies which play a major role in the flat screen technologies. These include the Multi-Domain Vertical Alignment or MVA and it is preferred at times because of its swifter response times and higher contrast ratios compared to many of the other techniques. However its reduced brightness is a setback. Another technique is the Twisted Nematic or TN which is among the commonest forms used for flat screen techniques. The other procedures include In-Plane Switching or IPS and Patterned Vertical Alignment or PVA. The use of these LCD techniques in the manufacture of flat screens are beneficial for several reasons like firstly it is space saving and also looks smarter and stylish and are slimmer versions. Moreover they do not suffer from burn-ins like the bulky television sets of earlier times.

However it must be pointed out that the presence of small film transistors in case of LCDs often lead to the formation of defective pixels thus affecting visibility and blurring or distortion of images. Sony, Samsung, Panasonic, LG, Toshiba, Akai are premier manufacturers of flat screens.

DSLR cameras

DSLR cameras also referred to as digital SLR cameras or digital single lens reflex cameras are different from the digital live preview cameras to an extent and they function with the help of a regular mirror system which is automatic and a significant feature called pentaprism which allows the light rays to be directed from the lens via the viewfinder. The functioning of the digital SLR cameras is dependent on several factors. In case of taking a photograph, at first the light rays are reflected by the mirror though the attached lens at a more or less ninety degree angle. At this juncture the pentaprism enables the light to penetrate into the eyes of the photographer. The final moment when the photograph is actually taken, the mirror takes an upswing thus enabling the lens to throw light into the image sensor. In case of the common digital cameras, the image sensors are constantly exposed to the light rays’ reflected by the lenses and therefore the screen itself becomes the electronic viewfinder. However, on the contrary the presence of the mirror in digital SLR cameras enables them to view the image in an LCD screen before finally taking the photograph. But nowadays it is found that a growing number of digital SLR cameras have also incorporated the live preview function as a result of which the LCD display is similarly used as viewfinder.

The digital SLR cameras are characterized by swift focusing properties and this is enabled by the phase detection autofocus system. Though several digital SLRs are using live preview properties, most of these possess the optical viewfinder and this is often more skilful in functioning as it unlike the electronic viewfinders they usually display the image as it is going appear as the final photograph as the light rays here are emitted from the lens itself. Some of the present manufacturers of digital SLRs include SLRs include Sony, Canon, Fujifilm, Panasonic, Olympus and Nikon

Computer flat screens

One of the most significant tools required for the functioning of the computer is the computer monitor which is responsible fro presenting all the imageries and actions on the computer screen and needless to say it is indispensable fro the proper functioning of the computers. While initially computer screens displayed images via the use of CRT or the cathode ray tube technology, at present flat screens have become prevalent and such screens like the TFL LCD are currently being used in computer monitor screens.

In fact it can be said without a trace of doubt that the LCDs or liquid crystal displays are the prominent technical tools used in computer monitors for the flat screens. Also plasma displays are emergingly becoming common in terms of usage in case of flat screen computer monitors. The various digital monitors are nowadays referred to as TTL monitors because of their allegiance to the TTL logic chips necessary for their functioning though the digital monitors now also support other technological tools like TMDS or LVDS protocols.

In the TTL monochrome monitors, two digital signals were responsible for controlling the electrons and consisted of an intensity bit to regulate the brightness of the pixels and also possessed a video bit as well. In the EGA digital monitors, a total of about six digital signals are employed and a specific signaling method called RrGgBb was used in order to control the activities of the six electrons. The electron gun here is placed in the intensity bit and this enables the primary colors to display in four different conditions thus allowing a total of 64 colors to be displayed in the monitor. In the CGA digital monitors the RGBI technology is used with four distinct digital signals employed to control the action of three electrons. The major flat screen digital computer monitor manufacturers include Apple, Sony, Dell, Acer, LG, Hewlett-Packard etc.
