LED display four big advantage

LED display as a start in the field of security monitoring shows, market development direction directly affects the security industry. Outdoor LED is LED industry development has incomparable advantages in intelligent traffic, an important development direction in the field of LED. With the unprecedented prosperity of the LED technology, LED display products high-profile, widely used in commercial advertising, live broadcast, induced traffic, stage demeanor, and other fields.

LED display four big advantage

In the outdoor advertising market, LED large screen advertising with aptness target consumption group has a strong, strong visual impact performance, flexible advertising update, one thousand people of low cost, large audience coverage higher advantages, has become the important media of outdoor advertisement.

Compared with LCD refresh machine, LED display the advantage of mainly reflects in the following:

1, the area of ductility, large LCD area is difficult to achieve seamless splicing, LED display can be arbitrary extension, and realize seamless splicing.

2, LCD, plasma screen flux decay quickly, generally run around one and a half years time, just need to change, but the LED display screen under the same operating conditions for at least five years no problem.

3, LED refresh machine can use interactive technology, strengthen the refresh machine as advertising media and audience interaction, such as cloud technologies to implement custom touch screen, broadcast control management, etc.

4, in terms of displays, LED display, high brightness, wide viewing Angle, and good color reproduction ability is better than that of the LCD screen. LED refresh machine is generally used in airports, shopping malls, hotels, high-speed railway, subway, cinema, exhibition, office, etc., the target customer consumption ability is strong, has the huge advertising value.

LED display of reference of choose and buy

LED the production process requirement is very high, and not all enterprises have the corresponding power, thus causes the market to the quality of the LED display the good and bad are intermingled. LED lamps and lanterns of the optical system design requirements is very precise and LED to the small size of pipe and condenser cup, the relative position of the two coordinate the demand is higher, small deviation, the position of the light reaches the stage there will be a big gap. In order to meet the design requirements, technical requirements strict consistency to large quantities of LED tube manufacturer screening, considering that the LED tube on the PCB solder paste thickness of the gap, the manufacturer will adopt automatic laser welding process.

In addition, heat dissipation problems directly affect the LED luminous efficiency. The high quality LED display from the design and technology can solve the problem of heat dissipation, can have more than thirty thousand hours of life, but with poor design or process LED display may be only a few thousand hours or even a shorter life span.

Professional development, design, strict production management, the enterprise from the selection of components, materials, from the advanced automation machinery to the production process of strict quality control (including the middle parts of aging treatment), each link affects the quality of the LED display.

So how to discern the stand or fall of the LED screen? The following points hope to bring you some inspiration.

LED display 1. The smoothness of the surface roughness to within + / - 1 mm, to ensure that the 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. The brightness and the viewing Angle of indoor full color 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. The white balance effect 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. The reducibility of color reducibility is 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 LED display 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. Whether the shades of 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.
