Zoom on digital cameras Although the number of small digital camera focal length mark, but the focal length range of about 50mm focal length range of general significance to the film camera (35mm size) as the base, below the 50mm range of focal length wide-angle region, higher than the 50mm range The focal length is a telephoto range, the focus changes to the region can be achieved through the operation of the zoom. The same position try to zoom to adjust the shooting range diagram Do not change the location of the zoom operation of the camera and the subject will find the screen to display the image will become larger or smaller. This is due to zoom lead to changes in the composition. Telephoto region will be subject to amplification, while the wide-angle region is narrow. Actually shown, the zoom changes through the shooting range to change the size of the subject in the frame. Understand this principle, can understand the use of wide-angle range and telephoto range, and can be

OLED industry growing fast In recent years, several international large company in the OLED product research, development and industrialization progress made and on behalf of the Product: 2000 companies such as Philips and Taiwan Ritec launch OLED displays for mobile phone display. Motorola Inc. started selling the OLED display phone. DuPont to invest $ 15 million to the U. S. UNIAX formation of polymer color LED 6inch test line. Philips company to invest $ 50 million to establish a 14-inch test line; Siemens Malaysia test line with a certain scale. In 2001 Sony introduced the TV-use OLED displays, the screen is 13 inches, 800 × 600 pixel count, 16. 7 million display colors, each pixel is driven by the four TFT. eMagin OLED microdisplays, launched the first full-color small molecule resolution of 600 × 3 × 852, there are 16M colors. Toshiba America Electronics Corporation announced the first full-color OLED prototype polymer light-emitting material, 2. 85 inches, 26,000 colors,

The purchase of men s shirts Fickle and women are different, urban male wardrobe, turn not too many tricks, too avant-garde trend of the object, it may seems out of place in the workplace; too conservative dark match, but also seems a lack of self and individuality. To additions to the new look of the season, what kind of clothing that allows you to easily access a variety of occasions, and keep the quality of the "sportsman"? Let us plan for you! Rule number one: classic timeless Export-oriented: The pattern of inward-looking: Check Popular is the "pretty boys", but too dazzling printing is probably only suitable for those who show the star. Life, the man is supposed to give the impression that a modest and charming image should not dress like only the "butterfly", careless self-defeating, would be a mockery! More importantly, the majority of women still appreciate the simple style of dress men. That is not a man can only wear the traditional blue, white, black and gray? NO! They c

led display classified Classification of a variety of LED display, generally classified in accordance with the following ways: (1) use of the environment is divided into indoor, outdoor and semi-outdoor Account the internal display area is generally less than 1 square meter to more than a dozen square meters, the point density is higher in non-direct sunlight or lighting environment, viewing distance in a few meters outside the screen body do not have the seal waterproof. Outdoor screen area is generally from a few square meters to tens or even hundreds of square meters, the point density is relatively sparse (mostly 1000-4000 points per square meter) brightness in the 3000-6000cd / square meter (toward different requirements are different, brightness) can be in the sun direct conditions, viewing distance in tens of meters, screen has good wind resistance to rain and lightning protection capability. Between outdoors and indoors between the two semi-outdoor screen, high brightness can

Ordinary monochromatic light-emitting diode Ordinary monochromatic light-emitting diode has a small size, low operating voltage, operating current, luminous uniformity and stability, fast response, long life, etc. , available to a variety of DC, AC, pulsed power-driven light. It belongs to the current control semiconductor devices, need to be connected in series when a suitable current limiting resistor. The luminous colors of the ordinary monochromatic light-emitting diodes with the wavelength of light, and light-emitting wavelength in turn depends on the semiconducto
