Shutter type 3D Technology

Shutter type 3D technology, English as Active Shutter 3D, with active shutter glasses using 3D. The 3D technology in TV and projector above most widely employed, resources are relatively more, but the image effect is outstanding, by many manufacturers praise and use, but the match 3D glasses price is higher.

Shutter type 3D is mainly by improving the screen refresh rate to achieve the effect of 3D, the image by the frame of one divides into two., forming the corresponding left and right eye two pictures, continuous interleaved display, at the same time, the infrared signal transmitter will be synchronized control shutter glasses side lens 3D switch, so that the left, the right eye to correct always see the corresponding image. This technique can keep the picture in the original resolution, easily allows users to enjoy true full HD 3D effect, and can not cause the screen brightness to reduce.

At present, including Samsung, Panasonic, Sony, sharp, Haier, Changhong brand launched 3D TV, are using active shutter 3D technology.

Shutter type defects:

1 after wearing glasses, brightness decrease more;

2.3D glasses switching frequency and fluorescent lights and other lighting equipment, in the bright room viewing comfort low;

3.3D lens shutter opening and the left and right image is not completely synchronized, will appear crosstalk ghosting;

The 4 shutter type 3D LCD TV viewing angle is small;

The 5 shutter type 3D glasses price in 1000 yuan, relatively expensive, and require the installation of a battery or a rechargeable use.

According to technical principle 　　Analog television, digital television 　　And the digital television (separates including the fission type digital television digital set-top box and monitor), a digital television body machine (digital set-top box and monitor conformity in together) according to demonstration proportion 　　4:3 16:9 5:4 16:10

　　In television's inch is the inch,dvb t tuners

what surveys is the diagonal line length: 　　1 inch =25.4mm 　

　Therefore 29 inches televisions, the diagonal line distance should be 73.66 centimeters. According to network function 　

　As a result of the Internet technology's development, the television surfer has become one tendency, the present television divides into the ordinary television and the Internet television according to the network function, if the user wants to let the original ordinary television promote as the Internet television, may also regard the valuable and so on Internet high clear selection and broadcast machine through nine water chestnut nets to realize the promotion likely.

World History

At the end of the nineteenth Century, a handful of pioneers began to study the design of image transmission technology. In 1904, the British Baer Will and the Germans, Ke Long invented a television electrical send a photo of TV technology, each one picture in 10 minutes. In 1924, the British and German scientists, almost at the same time using mechanical scanning mode successfully spread the still image. But the cable mechanical television transmission distance and the range is very limited, very rough image.

In 1923, American Russian scientists Zworykin apply to the kinescope, television transmitter and a television receiver of the patent, he first used the" comprehensive electronic television" sending receiving system, becomes the modern television technology pioneer. The application of electronic technology on television, the television began to move out of the laboratory,dvb t receivers

entered public life, 1925, British scientists successfully developed television. In 1928, the United States of New York 31 radio stations were the world's first television broadcast test, as the CRT technology has not yet been fully passed, the trial lasted only 30 minutes, watching TV is only a dozen, it declared as public utilities the advent of television art, in television history, an epoch-making event.

In 1929 the United States scientists Yves between New York and Washington over 50 lines of color television image, the invention of the color tv. In 1933 the Zworykin and developed for television camera with the camera tube and tube. Completed the TV camera and imaging fully electronic process, thus, forming the basic modern TV system. Today, television cameras and television imaging principle and apparatus,cable supplier is based on his invention to improve.

The United States launched the world's first RCA1939 black-and-white TV set, to set the color television standards as well as the 1953 1954 launch of the RCA color TV

The first television debut on 1924, by the UK Electronic Engineer John Baird invented, to 1928, the United States RCA TV station to broadcast the first set of TV film" FelixTheCat", from now on, television began to change the human life, the dissemination of information and the way of thinking. From then on, mankind has entered the age of television.

Bosom hall network planning organization, the invention of television may not be believed by scientists to be the greatest invention, but it should be related to the crowd 's greatest invention, through the invention of television, we shortened the distance with the world, which triggered the development of relevant industry is inconceivable, we must admit, TV, completely changed people's life.
