LED display act as a important role in security monitoring areas, marketing development impact the direction of the security industry directly. LED outdoor display gain an unparalleled advantage in the development of intelligent transportation, is an important direction of LED area development. With the development of LED technology, LED display products are widely used in commercial advertising, live broadcast, traffic induction, stage deduction and other fields.

LED display four advantages:

In the outdoor advertising market, LED large screen advertising has become an important outdoor advertising communication media with the advantages of strong relevance with target consumer groups, strong visual impact of performance, advertising updates flexible, Low labor costs, popular with customer and high coverage.

Compared with the LCD brush machine, LED display advantage is mainly reflected in the following points:

1. the area of ductility, LCD area is difficult to achieve a large seamless stitching, LED display can be extended, and seamless splicing.

2. LCD plasma screen brightness decay quickly, generally , you need to replace it after running a year or half of year but the LED display canoperating at least five years the same conditions.

3. LED scrubbing machine can use interactive technology to enhance the brush machine as the advertising media and the interaction between the advertising audience, such as custom touch screen, broadcast technology to achieve cloud management management.

4. In terms of display, LED display of high brightness, wide viewing angle and good color reproduction capability is also better than the LCD screen. LED flash screen machine is generally used in airports, shopping malls, hotels, high-speed rail, subway, theater, exhibitions, office buildings, target customers with high consumption level, having great advertising value.

LED display four advantages and optional reference

LED display optional reference:

LED production process requirements are high, not all companies have the appropriate strength, resulting in the quality of the market LED display varies greatly. LED lamp optical system design requirements are very precise, LED tube and condenser cup size is very small, the relative position of the two with a higher requirement, a small deviation, the light to reach the stage location will be a big gap. In order to meet the design requirements, the process requires manufacturers make a large number of LED tube consistency screening, taking into account the LED tube in the circuit board welding slurry thickness of the gap, manufacturers will use automated laser welding process.

In addition, the heat dissipation issue directly affects the LED luminous efficiency. Normally, high-quality LED display solve the heat problem in the design and process , The led have more than 30,000 Hours Lifetime, but the design or poor process LED display may be only a few thousand hours or even shorter life.

From the advanced automatic operation machinery to the strict quality control of the production process (including the aging of the middle parts), every link affects the LED display.

For the enterprise Professional development, design, strict production management, the selection of components, materials, advanced automation machinery, and the strict quality control production process (including the Product components of aging ), each process affects the LED display quality.

So how to identify the LED screen is good or bad? The following points hope to bring you some ideas.

1. Surface flatness:

Screen surface roughness to within + / - 1 mm, to ensure that the display image is not distorted, local convex or concave leads to display the visual Angle of corner. The stand or fall of flatness is mainly decided by the production process.

2. Brightness and viewing angle:

Indoor full color LED display brightness to above 800 CD/m2, outdoor full color brightness to above 1500 CD/m2, to guarantee the normal work of the screen, otherwise it will because the brightness is too low and can't see shown in the image. Mainly by the size of the brightness of LED tube core is good or bad decision. Viewing angles directly depends on the size of the display screen of the audience, and the bigger the better. The size of the viewing Angle is mainly composed of tube core encapsulated way to decide.

3. White balance effect:

The white balance effect is one of the most important indicator display. Chromatology on red, green and blue color for the proportion of 1:4. Lost. 16 will only show the pure white, if the actual rate is a little deviation will appear white balance deviation, generally pay attention to whether there is a slant blue, white slant yellow phenomenon. The stand or fall of the white balance is mainly composed of display control system to determine, tube core of color reducibility may also be affected.

4.Color reducibility:

Color reducibilityis refers to the display of color reducibility, the color of the display shows both to maintain highly consistent with the colour of the source, so as to ensure the image sense of reality.

5. For the Mosaic, dead center

Mosaic refers to appear on the screen normally on or often black small four squares, both module necrosis phenomenon, the main reason for the display of connectors quality closes nevertheless. Dead point refers to appear on the screen normally on or black often a single point, how many of the dead point mainly determined by the stand or fall of pipe core.

6.Color piece:

Color piece is refers to the adjacent modules between relatively clear off color, color transition in module, color piece phenomenon caused mainly by the control system is poorer,grey level is not high, caused by lower scanning frequency.
