Is there a way to make the LED outdoor visual big TV?
The answer is yes.
Summarized the following methods: five manufacturers, the influence of the pixel pitch pixel spacing of articulation is very obvious, the smaller the pixel pitch, it showed more exquisite.
Narrowing of the pixel pitch must have a mature technology as the core support, from the current trends, pixel pitch reduction is the inevitable choice of the market.
However, relatively, pixel spacing is smaller, the greater the cost of its investment, the higher the price.
Screen flatness and surface reflectance LED display screen body of local convex or concave leads to display the visual Angle of blind Angle, the surface roughness to within + / - 1 mm, to display the image is not distorted, the buds of LED display based on the panel and LED tube for special craft processing, while guarantee the screen surface roughness lower reflectivity of LED panel, also can improve the contrast of the display (
The higher the contrast, the easier the eyes distinguish dynamic light conversion process of the image)
Third, LED display gray level gray level refers to the full color LED display
from the darkest to the brightest in the single color brightness can distinguish between the brightness of the series, gray level is higher, the color is rich, colour is gorgeous;
On the other hand, according to a single color, simple changes.
Grey level enhancement, can greatly enhance the color depth, making image color shows an geometric increase in the number of levels.
The buds of COB full color LED display USES the high quality LED lights, small spacing low light high ash, bright images clearer and more exquisite quality.
