Full color LED large screen is fully applied in the field of radio and television is the inevitable trend of development

In the rapid development of radio and television technology today, more and more TV stations and production units used program production and broadcast high-definition technology, and more flexible studio backgrounds has become a problem of traditional background and cannot be solved by the virtual studio. As more and more requirement of visual enjoyment, as has the industry leading technology R & D team of professional LED large screen screen manufacturer, our company formally to the radio and television program production and the launch of the new LED application system across the significance of solutions.

LED series - truly universal background LED full-color large screen

Our company is Shenzhen veteran professional LED large screen curtain system products manufacturer, it use the advanced technology and experience for the market to provide the best LED large screen display products. We also provide LED large screen video system solutions for a number of provincial TV news studios, and these large screen video solutions to meet the high-end requirements of indoor applications. It has unique technical advantages in video performance, gray level and color accuracy.

Is above 700 square meters of a British news studio Sky TV just renovated, you can see that there is two "Sky NEWS Today", they are displayed by two LED full-color screen. This is a typical example of the application of LED large screen screen in the radio and television industry.

LED display application field actually has been several years in the big screen, full-color LED large screen screen into the Chinese time is relatively long, is widely used in the field of radio and television in the background video wall stage, a large studio and the party.

My company has a large screen LED screen display a variety of other equipment which does not have the advantage: the contrast and brightness of LED large screen curtain is high, working in an outdoor environment LED screen can reach 5000nit, is 10 times of common LCD screen brightness, even in high ambient light conditions, still can provide a clear display effect. - LED large screen screen can do very large, basically no area restrictions, can meet the needs of remote viewing. The reason is that led large screen screen is made up of a box body, the number of boxes can be added to build a larger area of the screen, so you can create a spectacular display.

Above Sky TV as a full-color LED large screen screen background is the main area of 42 square meters (14mX3m), LED full color screen used in the stadium is usually 150 ~ 200 square meters between. - LED large screen screen can be designed into the shape of the surface or cylinder, Sky TV of these two LED screens are concave arc LED large screen, the traditional LCD or plasma is not the physical form of such a special screen.

Although the LED screen is composed of a plurality of box splicing, but the gap can be spliced through a variety of technical control is very small, very high consistency screen display, so look from visual effect no seams exist, as shown in the right figure below. Other splicing screen has a large mosaic gap, can not eliminate the prison sunroof effect, as shown in the following figure.

Let us from a large screen LED screen to display the analytic principle. LED large screen is composed of a number of boxes, each box has a different resolution pixels. For example: Sky TV the main background of the model point spacing is 6mm, the resolution of each box is 72x72, you can calculate the main wall Sky TV resolution is 2016x432. The pixel is R, issued by G, the LED lamp B three different colors, can according to the different ways of packaging will be divided into 3 full-color LED large screen curtain 1 surface mount type or single lamp type, Sky TV is used in LED lamp is shown below:

Also a large screen LED screen is composed of a single lamp, used in outdoor applications, the single lamp photos and form a pixel:

Each pixel LED has R, G, B three kinds of light, so when the emitting color of each lamp is different, the pixel will show the different color mixing, LED screen is because the color of each pixel to show the effect of a riot of colour is gorgeous. LED is the abbreviation of Light Emitting Diode, Chinese name is light emitting diode, is a kind of semiconductor solid state light-emitting devices, the use of solid semiconductor chips as light-emitting materials. When the two ends with forward voltage, the semiconductor carrier and the majority of minority carrier recombination, release of excess energy caused by photon emission, directly emit red, orange, yellow, green, green, blue, purple, white light. Due to the production process, each LED lamp display characteristics is not exactly the same figure shows the test results of color coordinates of LED lights, even the color characteristic of world-class LED lamp manufacturers produced the same batch of LED lamp is distributed in a phase of the region.

Due to the characteristics of LED itself, in order to get a perfect image quality, strictly control the LED display consistency becomes the key. We use pixel level color correction techniques to ensure consistency of display. System color signature technology can color coordinate monitoring box on each LED lamp, and these parameters will be recorded in the case of the programmable read-only memory, when LED full color screen controller is connected to the box body through a data line, you can read every pixel parameters and display output correction, it can guarantee the whole the box to display the entire screen line.
