(1) Permeability

Permeability is the core of transparent display effect of LED transparent display. Choose the unidirectional light strip structure. The LED chip is installed on the optical strip, the width of the optical strip is 10mm

(2) side glow

LED side glow was developed for transparent screens. The glowing colors are directed towards the hollow parts, which makes the image more realistic and clear. At the same time, the air display effect will be more perfect

(3) pixel spacing

The effect of pixel spacing on sharpness is particularly noticeable. The smaller the pixel spacing, the finer the picture. Based on current trends, pixel pitch reduction must have a mature technology, as the core support, pixel pitch reduction is the inevitable direction of the market. But the smaller the pixel spacing, the higher the cost and the higher the price.

(4) Flatness of reflectance of the screen body and the surface of the screen body

Local convex or concave LED display will lead to display Angle dead Angle, surface flat within ±1mm, can ensure that the display image will not be deformed, LED display panel and LED tube for special processing, to ensure the screen surface flatness

Ile reduces the reflectivity of LED panels, and it also improves the contrast ratio of the display (the higher the contrast, the easier it is for the human eye to recognize the transition between light and dark in a moving image).

(5) Gray level of LED display

Grayscale refers to the level of brightness that can range from the darkest to the brightest level of brightness, in a single primary color brightness of a full color LED display. The higher the grayscale, the richer the color. Instead, the display color is single and simple to change. The improvement of gray can greatly improve the color depth, so the image color display level is expressed as an increase in geometric numbers. Small pitch LED screen selection of high quality LED lights, low bright and high gray, picture clearer, bright, picture quality is more exquisite.

(6) Bead quality and failure rate

The LED display consists of thousands, thousands of red, green and blue LED beads. Over time, LED beads will gradually disappear as brightness increases. The rate of attenuation of LED bead brightness is related to LED chip, auxiliary material and packaging process.

(7) Use stability and safety

The box design of the LED display is very important, the heat conversion temperature of the components will increase, and the image quality will decrease. Therefore, good ventilation and heat dissipation design is essential. On the one hand, protection circuit protection, safety and dust-proof, waterproof effect.
