Answer the secret of the LED screen construction
In the process of learning about the LED screen, it is certainly impossible to wonder, what is the composition of the LED display? Understanding the structure can be helpful in many situations such as fixing minor errors in technology, or understanding the principles of operation, or simply, you just need to learn to improve your understanding of devices. effectively displayed!
What is the led screen?
Before learning about LED display structure, for those who do not know the specific concept of this type of device, the following knowledge is quite useful. LED is the acronym for Light Emting Diode - a device that can replace TV, a projector that displays information, images, or different videos.
Made from light-emitting diodes, colors displayed from the basic color system RBG ("R" - red, "G" - green, "B" - blue) help display vividly the projected content . LED screens now have many technological improvements, also known as transparent led screens (http://luxmage.com/tin-tuc/man-hinh-led-trong-suot-la-gi- 214.html) support many businesses in promoting brand image.
What does the led display include?
Previously, conventional led screens made up each module to assemble many modules that would produce larger screen sizes according to specific uses. Existing module sizes include: 128 * 128mm, 160 * 160mm, 192 * 192mm, 256 * 128mm, 320 * 160mm.
Particularly for LED displays throughout the module size, it is very flexible, depending on the purpose of use, they have many different lines, with different sizes. For modules installed in modules, each module size is 1000mm * 500mm.
Each LED module's structure includes the following sections
Pixels: each LED module has an infinite number of pixels, each of which is made up of 3 blue, green and red LEDs. When adjusting the relative light intensity of 3 LEDs together and creating a composite color at each pixel. So that when you want to turn off the screen just turn off all 3 LEDs, the screen will light completely without having an unrealistic black phenomenon exposing light from the backlight like LCD screen.
To be able to illuminate the image across the background, the LEDs must be aligned with 1: 1 with the color pixel matrix. With such an arrangement, it is possible to adjust the most accurate brightness to every pixel on the entire screen, with better contrast and eliminate color difference in corners. So the bigger the screen, the more LED points you need.
The transparent led screen has many structural features that show the superiority of the LED like: Each module only includes:
Stick with many LED bulbs distributed thick or thin depending on the resolution suitable for the type of screen
Lightweight aluminum frame to fix module to standard size
Simple conductors are located in aluminum frames without exposing them to cause aesthetic loss
External parts: to control the LED effect as well as the appropriate parameters, the product also has a control box, receiving card, CAT5 cable, DVI cable, Plexglass cover, etc.
Wide application of led displays
Today, we can easily see a large led screen anywhere: event theater, festivals, conferences, advertising signs, traffic signs, restaurants, hotels, resorts, hotel, ... from small size to big screen, from small details to luxurious places. This is increasingly showing their advantages and applications in daily advertising activities.
Not stopping there, when technology is growing, it is also when more advanced new products are born. Transparent led screen is also one of them, inheriting the characteristics of common LED applications, transparent LEDs can also be expanded to applications in many other areas without disappointing customers, ensuring brand High-pitched fruit.
