Hello, there must be four factors for led to realize HD display: first, the film source requires full HD; Second, the display should support full HD; The third is to reduce the point spacing of LED display screen; The fourth is the combination of LED display and video processor. At present, led full-color display is also moving towards higher definition display.
Hello, there must be four factors for led to realize HD display: first, the film source requires full HD; Second, the display should support full HD; The third is to reduce the point spacing of LED display screen; The fourth is the combination of LED display and video processor.

LED display fuzzy, how to check?

at present.
LED full-color display is also moving towards higher definition display.

1. Improving the contrast of LED full-color display is one of the key factors affecting the visual effect.
generally speaking, the higher the contrast is, the clearer the image is, and the brighter the color is.
the higher the contrast is, the clearer the image is, and the brighter the color is Gray level performance is very helpful.
in some text and video displays with large black-and-white contrast,
high contrast full-color LED displays have advantages in black-and-white contrast, clarity, integrity, etc.
contrast has a greater impact on the dynamic video display effect.
because of the fast light dark conversion in dynamic images, the higher the contrast, the higher the contrast, It is easier for human eyes to distinguish such conversion process.
in fact.
the enhancement of contrast of LED full-color screen is mainly to improve the brightness of full-color LED display screen and reduce the surface reflectance of the screen. However, the brightness is not the higher the better. If it is too high, it will backfire, which will not only affect the life of LED display screen, It can also cause light pollution.
light pollution has become a hot topic.
too high brightness will have an impact on the environment and people.
the LED panel and LED light-emitting tube of full-color LED display screen can be treated by special process.
it can reduce the reflectivity of LED panel and improve the contrast of full-color LED display screen.


2 Improve the gray level of LED full-color display screen

the gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of LED full-color display screen.
the gray level of LED full-color display screen can be improvedThe higher the gray level of cloud sea full-color LED display, the richer the color and the more gorgeous the color; On the contrary, the display color is single and the change is simple.
the improvement of gray level can greatly improve the color depth, With the development of hardware technology, led gray level will continue to develop to higher control accuracy.


3 Reduce the point spacing of LED full-color display screen

reduce the point spacing of LED full-color display screen.
can improve its clarity, the smaller the point spacing of full-color LED display screen, the more delicate the picture display.
however.
this point must have mature technology as the core support, the investment cost is relatively large, and the price of the full-color LED display screen is also high, But fortunately, the market is also developing towards small spacing LED display.


4. Led full-color display combined with video processor can use advanced algorithms to modify the signal with poor image quality.
perform a series of processing such as de interlacing, edge sharpening, motion compensation, etc. to enhance the details of the image, Improve the image quality.
use the image scaling algorithm of the video processor.
to ensure that the clarity and gray level of the image can be maintained to the greatest extent after the video image is scaled.
in addition.
the video processor also needs to have rich image adjustment options and effects to process the brightness, contrast and gray level of the image, In order to ensure the soft and clear screen output.
this method is simple and effectiveOr you can use Baidu to learn more   Web links    . release time: June 6, 2013 news source: last article of Tongpu Technology: what details do you need to pay attention to when customizing LED display? Next: what are the advantages of LED display compared with traditional advertising? As a way of advertising, LED display has been very common.
its publicity effect has exceeded many people's expectations. While using LED display to send advertising information is convenient, many friends who have just contacted will ask, how can I change the words on LED display, through mobile phone, computer or USB flash disk? In fact, it's not very difficult. Each LED display is equipped with a control card and software. After the screen is installed, connect the control card and the power supply, copy the software to the computer, and you can directly operate it on the computer, which can modify the text content and scan mode, Generally, we suggest using USB or GPRS.
to save time and effort. If you use GSM SMS control card in LED display, you can use your mobile phone to replace the advertising content on the display, and you can send and change the advertising subtitles by editing SMS; If you are using the U disk control card, If you want to change the content on the LED screen through the computer,
this method is more selective.
but it still depends on the actual demand.
for example, some stores use it in their own stores.
we would recommend using wired control card, It can be sent through the computer.
or it is recommended to use the U disk control card instead of connecting the line.
it is recommended to use the U disk control card instead of connecting the lineIf you want to change the advertising content, you can directly copy it with U disk.
if the LED display screen is distributed in various districts.
or bus stops, chain stores and other places, if you want to send it collectively, it's easy and fast.
it's recommended to use GPRS wireless control card.
edit the content in the computer software, and send it in groups with one click.
it's time-saving.
it's labor-saving.
