What's the factors that affect the display effect of led display

There are many factors affecting LED display effect, such as brightness, screen pixel pitch, surface flatness, lamp attenuation and the failure rate, the use environment and so on. Here, TCB will explain the five factors that affect the display effect of the LED display.

P4 Indoor Led Display

One, pixel pitch

The affect of pixel pitch on clarity of screen is very obvious. The smaller the distance between pixels, the more delicate the picture is displayed. The reduction of pixel pitch must have mature technology as the core support. From the current trend, the reduction of pixel pitch is the inevitable choice of the market. However, the smaller the pixel pitch, the greater the cost of its input and the higher the price.

Two, the flatness of the panel and the reflectivity of the panel surface

The convex or concave of led display will cause the dead corner of the viewing angle. Surface roughness should be within ±1mm, to ensure the display image is not distorted. TCB LED display have special treatment on mask and LED light tube, in order to ensure the smooth surface of the screen while reducing LED panel reflectivity. It can improve the contrast of the display (the higher the contrast, the easier is the human eye to distinguish the dark and light conversion process of dynamic image).

Three, LED display screen gray scale

The gray scale is the brightness level that can be distinguished from the darkest to the brightest in the full color LED display. The higher the grayscale, the richer the color and the brighter the color. On the contrary, the color is single and the change is simple. The enhancement of gray scale can greatly improve the color depth, which makes the display layers of the color of the image increase in a geometric number. TCB small pitch LED display screen use high quality LED lamps, with low brightness and high gray scale, the picture is clearer and brighter, the quality of the image is more delicate.

Four, lamp quality and failure rate

The LED display is composed of tens of thousands or even hundreds of thousands of groups of red, green and blue LED lamp. With the increase of using time, LED lamp brightness will slowly decay. LED lamp brightness decay rate has some relevance with LED chip, auxiliary materials, encapsulation process. In general, after light for 1000 hours with 20 mA at room temperature, the red light attenuation of LED lamp should be less than 7%, the attenuation of blue and green LED lamp should be less than 10%. The consistency of red green and blue attenuation has great influence on the white balance of LED display and then affect the fidelity. At the same time, the lamp failure rate of good led lamp is low, even after 72 hours aging, the failure rate is not higher than 1/10000.

Five, use stability and security

The stability and safety of LED display is particularly important when running. The design of LED display cabinet is very important. The increase of the temperature of component thermal conversion will lead to the deterioration of image quality. Therefore, a good design of ventilation and heat dissipation is an important and indispensable index in the design of the cabinet. On one hand, it is the protection of its circuit, on the other hand, it is safety and so on, as well as the role of dustproof and waterproof. At the same time, should not use the power supply only at low prices and ignore the quality and performance. Under different temperature conditions, the stability of the work, the output voltage and the load capacity of power supply will be different, it undertakes after sale guarantee, so the safety performance of it directly affects the quality of the picture.

G-energy Power Supply JPS300V

After ensuring the above five points, in order for the LED display to achieve the best display effect, still need to ensure a good use environment. If the actual working temperature exceeds the product's prescribed range of application, it will not only shorten its life, but also seriously damage the product itself. When shooting, we should pay attention to the best shooting distance. The appropriate shooting distance is different with different pixel pitch led display. Of course, when selecting LED display product, users should choose a formal LED display manufacturer to ensure the quality, price and after sale service of the led display.
