What are the characteristics of LED full color screen?

Due to its long outdoor operation time and large amount of outdoor full-color screen, the screen body pays great attention to the pursuit of stability, good waterproof performance, good picture quality, large visual range, high brightness, energy saving and other characteristics.

To this end, we have done a series of work at Focus Technology:

1. Guarantee the stability of the screen body - control the production process, do 30 degrees Celsius to 65 degrees Celsius high and low temperature impact experiments, 48 hours of high temperature aging experiments, simulated transportation vibration experiments, etc., drive IC, power supply, plug-in parts and other components to select brand components, according to the utilization rate of 80 power supply, etc.;

2. Waterproof guarantee - use international brand LED special potting matte glue, and do IP65 protection water filling test on the front of the box used by the factory;

3. Picture quality assurance - according to the principle of three primary colors and the different attenuation curves of red, green and blue LEDs, the brightness of three-color LEDs is reasonably matched, and a screen uses a grade of LEDs; **Application of processor, application of single point correction system, etc.;

4. Viewing angle guarantee - select large viewing angle LED, and set the best viewing angle range of the screen according to the amount of application site; The application of outdoor three-in-one LED can make the upper and lower viewing angles of the display exceed 120 degrees;

5. Brightness guarantee - set the maximum brightness of the display screen (generally the brightness of 130 in normal use) according to the user's use site and the direction of the screen display, the driving current of the LED is set to be less than 18 mA, the screen is used for 2 years, and the brightness attenuation is less than 20;

6. Energy-saving guarantee - the automatic ambient brightness adjustment system is used to automatically change the brightness of the screen under different external brightness conditions.

LED full-color screen application scope: mainly suitable for cultural squares, traffic arteries, stations and docks, information centers, entertainment venues, shopping centers, commercial cities and other outdoor places of advertising, information release, news broadcasting, etc.

The sharpness is very high, and it looks three-dimensional.

One. Forward projection.

Forward projection is the front projection, the advantage of this display device is that the installation is simple, the picture is complete, but the disadvantage is the low resolution, two. DLP rear projection splicing.

DLP splicing wall is spliced by a plurality of display units, its main feature is the large size of the screen, and the seam is small, the mainstream size is 50 inches, 60 inches, 67 inches, with the increase of user demand for large screen size, 80 inches, 84 inches, 100 inches, 120 inches are also gradually used.

However, due to the characteristics of DLP rear projection splicing, there are obvious shortcomings, the larger the screen, the color and brightness will be uneven, and the internal luminous bulb will work continuously for 6000-8000 hours, and the brightness will be reduced. In order to maintain a good display effect, the bulb needs to be replaced at the end of the application, so the maintenance cost is very large. In addition, due to the large thickness of the DLP splicing unit, it is also necessary to leave enough space on the back of the screen body, which is a problem for some installation places with small space.

Three. LCD splicing.

LCD LCD splicing is following DLP splicing, PDP splicing, in recent years after the rise of a new splicing technology, LCD LCD splicing wall has low power consumption, light weight, long life (generally can work normally 50,000 hours), no radiation, uniform picture brightness and other advantages, but its biggest disadvantage is that it can not be seamlessly spliced, which is a big flaw for industry users with detailed and coherent display screens.

Since a single LCD screen will have a frame when it leaves the factory, the border (seam) will appear when the LCD is spliced, such as the frame of a single 21-inch LCD screen is generally 6-10mm, and the seam of the two LCD screens is 12-20mm. In order to reduce the splicing gap, there are several practices in the industry, one is narrow slit splicing, the other is micro slit splicing, micro stitching is that the manufacturer will buy back the LCD screen shell removed, the glass and glass splicing, this practice is more risky, if the single LCD screen is not well disassembled, it will damage the quality of the entire LCD screen.

Four. LED display.

With the continuous reduction of the spacing of the LED large screen and the continuous improvement of the resolution, in some areas with high use requirements, it has been completely able to replace the traditional large-screen display wall, and at the same time, the LED large-screen image is complete without a seam (strictly speaking, the seam is almost invisible to the naked eye), the size is not limited, the brightness of each part is highly consistent, the image level is rich, the color is uniform, whether it is a split-screen display or a combination of a large-screen display is extremely perfect, and the display effect is significantly higher than the traditional display mode.

Full-color outdoor LED display, thanks to the rapid development of outdoor advertising, is growing rapidly at a rate of more than 25% per year, with their vivid and real visual experience, making full-color LED display an indispensable member of the outdoor advertising carrier. Especially in the commercial center of the city, the most dense places, outdoor full-color LED displays can be seen everywhere. Due to the particularity of the environment, the outdoor full-color LED display is much higher than other conventional LED displays in terms of performance and quality requirements

2. Low energy consumption, energy saving and emission reduction, outdoor full-color LED display must be called for accordingly, and energy conservation and emission reduction must be implemented as an important standard in manufacturing, including product power consumption, product scattering performance and the amount of steel structure required for product installation.

3. The main task of the outdoor full-color LED display is to advertise and promote the image, therefore, so that more audiences can see the picture is the primary goal of the outdoor full-color LED display.

Indoor LED full color screen.

PH2, PH4, PH5, PH6, several models (the mainstream of the market is generally PH6 and.

Indoor LED full-color screen**: Indoor full-color screen is also divided into two styles, three-in-one and three-and-one**, with a gap of about 10,000 per square meter.

The die of the indoor full-color screen is also divided into domestic general chips (4 categories), domestic advanced chips (3 types), American advanced chips (2 types), and Japanese advanced chips (1 type). The highest grade is the original Japanese Nichia advanced chip (Class 1). On average, each square meter is about 10 times more expensive than the national shed collapse.

Outdoor LED full color screen.

PH10, PH12, PH16, PH20, PH25, several types of chain source French numbers (the mainstream of the market is generally PH12 and PH16).

Outdoor LED full-color screen**: The die of the outdoor full-color screen is also divided into domestic general chips (4 types), domestic advanced chips (3 types), American advanced chips (2 types), and Japanese advanced chips (1 type). The highest grade is the original Japanese Nichia advanced chip (Class 1).

On average, each square meter is 1 to twice more expensive than domestic ones.

Features of led display:

Compared with other large-screen terminal displays, LED displays mainly have the following characteristics:

1. High brightness: The brightness of the outdoor LED display is greater than 8000mcd m2, and it is the only large-scale display terminal that can be used outdoors around the clock; The brightness of the indoor LED display is greater than 2000md m2.

2. Long life: LED life is more than 100,000 hours (ten years), this parameter generally refers to the design life, and the brightness is dark;

3. Large viewing angle: indoor viewing angle can be greater than 160 degrees, outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light-emitting diode.

4. The screen area can be large or small, as small as less than one square meter, and as large as hundreds or thousands of square meters;

5. Easy to interface with the computer, and the support software is abundant.

I'm also learning this, and I happened to see a blog the other day that was written very carefully.

Thin and narrow, these two are the characteristics of the appearance, and in addition, LEDs are more energy-efficient than LCDs.

Search. The screen answers your questions:

1.The larger the viewing angle, the better, and the larger the display, the higher the audience;

2.The brightness of the indoor full-color screen is more than 800cd m2, and the brightness of the outdoor full-color screen is more than 1500cd m2 so that the display screen image will not be seen clearly because the brightness is too low;

The surface flatness of the display screen is within 1mm to avoid distortion of the display image;

5.White balance is one of the most important metrics of a display. In chromatology, when the ratio of red, green and blue primary colors will show pure white, if the actual proportion is a little deviation, there will be a deviation in white balance, generally pay attention to whether the white is blue, yellow-green.
