Projector, is taking a large view of things when it is used, the effect much better than LCD TVs.
But the three giant home appliance industry - television, refrigerators and washing machines, even fast-growing, the leading home appliance TM to the activities or the three, but added two new members, computers and air conditioning. In the home appliance industry, the traditional CRT TV to occupy the long-term dominance appliances, who succeeded the new main fact? LCD TV and plasma, have been fighting hard in recent years, due to the rise of the computer industry, the liquid crystal display abnormal development of rapid, so that LCD TVs shine in the battle situation. However, LED television was born, declared this war without end in the TV official to enter the three hegemony.
As the power life of brightness, and many other advantages, LED TV appears to fame, in fact, this product is also a transitional product, then the projection when the opportunity to enter the ranks of home appliance giant, then, what means and TV fight it?
True = LED screen LED TV + LED backlight
Really do not need backlight LED screen, LED is a light-emitting diodes, light source originally.
So, now inside the mall are selling LED TV LCD TV with LED backlight, is the concept of fry, just use the LED backlight technology, not the true meaning of LED TV. Is there a real LED display screen? The answer is yes. Plaza, stadiums, outdoor billboards used by large big-screen, LED technology is the real. To close contact with the real LED products around the Bird's Nest in Beijing, tens of meters one can easily glimpse of its "hosting the Games." Arm's length, large size, close look, thick "diode" eyeful of color bulb matrix. Do not see images from 10 meters, which makes it difficult and TV par. Because of the technology and cost constraints, real LED TV is estimated to be 5 to 10 years to market.
Real LED display technology
And use the LCD backlight compared to CCFL, LED backlight really saving. Such as Samsung 46B6000, electricity as long as 18.73 U.S. dollars per year, while Samsung CCFL LCD TV 46B650, electricity has to cost 25.96 U.S. dollars per year, more than 28% LED models. Then compared with plasma TVs, Panasonic Plasma P46G10, spend a year of electricity is 60.69 U.S. dollars, is 3 times the LED television. However, this tariff, select the LED models spend more than the cost of this expenditure is minimal. This contrast, LED backlight with LED models, in fact, much better than this.
LED dot matrix
If technology allows, to create a level of true 1080P LED TV, more than 50 inches in size, and to a pixel corresponding to a LED light, then a TV will need 2.1 million LED, quality tends to achieve perfection. However, such products do not the ultimate energy saving, but also a great waste. LED is a collection of contradictions, how to balance the quality and the relationship between the number of LED used, the issue almost "mission impossible." LED to be more energy-saving, LED number to be more, LED should be smaller, and can only hope to change the material.
Three stories, well known, Wei Shu Wu Sanguo Dingli decades, the final is not powerful Wei, but the unification of the world instead of Jin. Display equipment manufacturers all bets are pressed the LED technology; looks promising LED TV, in fact, Wei; the key is just the first to perish Wei powerful one. We are beginning to universal access to multi-core processors, but the progress of LED technology is still 286 stage.
Its futile to wait for the "arrival of the King", the real emergence of LED TV than to switch attention to the projector. The future of television, perhaps the flat LED projectors and leave the race. As the projector has been developed nearly 20 years, projector technology continues to improve, the key is to keep their prices the past two years, diving, common people, family oriented, popular. Projector LED light source technology in the rapid development of LED technology is mature when the time is the evolution of the LED projector, perhaps also the end of the day flat-panel TVs.
Can eradication of projection into the living room flat panel television supremacy?
Regardless of the projector, flat panel TV, or traditional CRT TVs have one thing in common, with numerous, looking confused, and sometimes we know what to do - the interfaces.
Sony flat-panel TV in the number of the largest number of interfaces. For example, our products for Sony KDL-55X4500, which is a 55-inch HD LED TV, Sony KDL-55X4500 number of interfaces with nearly 40 through the video interface statistics are classified as: 3 Group AV input, AV output group 1 2 group component video input, 4 HDMI inputs, a group S terminal input. As the TV as a display output device, a number of group video input, audio output interface, a number of groups beyond reproach, but so many, it is not meaningful increase in our investment out of thin air is not, allows the practice resulted in excessive a sense of confusion. Input and output, the one group is more rational configuration.
Complex interface LED TV
Mitsubishi flat-panel TV in the number of the interface is most professional. Examples of products our Mitsubishi LDT461V, this is a 46-inch HD LCD TV, Mitsubishi LDT461V interface, the number of 27 or more, through the video interface statistics classified as: group 1 BNC input, 2 HDMI input group, a group VGA input , a group VGA output, a group of component inputs, a group of AV input, a group S terminal input. BNC video interface which is professional, VGA is the preferred interface to connect with the computer.
In contrast to high-definition flat-panel TV product, in the light of the projector for 1080P-level products. As the TV does not distinguish between industries, there is no distinction between the concept of non-professional; the projector at this stage there is a clear distinction between the industries, professional-level distinction between strictly positive. Our products are all listed projector civilian level, household products, or audio and video entertainment products.
First introduced the Mitsubishi HC3700, which is a home theater projector, using DLP technology, 1050 lumens rated brightness, contrast 10000:1; Mitsubishi HC3700 has nearly 15 interfaces, including: Group 2 HDMI inputs, 1 BNC input group , a group of component inputs, a group S video input, a group of AV input, a group TRIGGER and a group of 9-pin serial port interfaces.
In addition, the Epson TW4500 3LCD has used technology, nominal 1600 lumens, contrast ratio 20000:1, because of its excellent quality performance in the recent concern has been the highest in the 1080P theater projector. Epson TW4500 only has 11 interfaces, including: Group 2 HDMI inputs, a group of component inputs, a group S video input, a group of AV input, one VGA input group, a group of 15-pin serial port and a group of Tigger out interfaces.
On the surface, the projector brought the number of interfaces is much less flat-panel TVs and more, especially in the audio, the projector can be described as the interface is more pitiful. Actual use of, display terminals, external equipment will not be many, there is already enough for several commonly used. 2 two home projectors, but is subject to domestic constraints, interfaces, is also a small number of reasons.
HDMI's full name: "High Definition Multimedia", according to the latest Chinese SARFT issued a notice can not be used for short, it's full Chinese name: high-definition video and audio digital multimedia transmission interface. HDMI interface indicates the emergence of grand unification, not only unified video interface, but also unified the audio interface. HDMI is DVI on the projector in addition to outside only digital interface, in the past usually only in high-end products, with product promotion, HDMI also began to spread in the low-end models. High Definition Multimedia Interface HDMI is the English abbreviation, Chinese name is called high-definition multimedia interface, can be high-quality transmission of uncompressed high-definition video and multi-channel audio data, the maximum data transmission speed of 5Gbps, while no signal before transmission D / A or A / D conversion, can guarantee the highest quality audio and video signal transmission. HDMI not only the highest quality to meet the current resolution of 1080P, but also support DVD Audio and other advanced digital audio format that supports 8-channel stereo 96kHz or 192kHz digital audio transmission, and only one HDMI cable, remove the digital audio cable . HDMI technology not only provides a clear image quality, but the audio / video using the same cable, which greatly simplifies home theater system installation. Moreover, with the popularity of HDMI, connection BOX360, PS3, high-definition entertainment players, such devices become more convenient.
HDMI advantage
With the HDMI interface, other non-exclusive and non-professional interface, the market will gradually fade out. With HDMI, more, colorful, large and small video and audio interfaces are superfluous.
Computer, and now almost every family must have the electronics, even appliances boss of TV coverage than the higher. Electronics and computer connections are essential to an important function.
TV, projector, while tough, if not connected to the computer, it is estimated that many consumers will look and stop. Computer and external connection ports, mainly in graphics, sound card and network card, USB's powerful scalability should not be overlooked.
