With the development of LED display, there are many types of LED display, such as rental LED display, transparent LED display or high-definition small-pitch display, etc. So which should we choose? Which is better?
Take the more commonly used ordinary LED display and high-definition small-pitch display as an example, let’s take a look at the advantages of both.
The advantages of LED display
1. Seamless stitching
The splicing large-screen display technology can never avoid the influence of the physical frame when it meets the needs of customers to the greatest extent. Even if the ultra-narrow-edge DID professional LCD screen still has very obvious splicing seams, only the LED display makes the splicing seam seamless. Seam requirements, the advantages of high-density small-pitch LED seamless splicing are highlighted.
2. High brightness intelligently adjustable
The LED screen itself has high brightness. In order to satisfy the comfortable viewing effect for the viewer in the strong light environment and the dark light environment, and avoid visual fatigue, the brightness can be adjusted with the light sensing system.
3. High gray level for better color performance
Even if the grayscale performance of the display screen is almost perfect at low brightness, the layered and vividness of the displayed picture is higher than that of the traditional display screen, and it can also show more image details and no information loss.
4. High contrast, faster response speed, high refresh rate
The number of times the electron beam repeatedly scans the image on the screen. The higher the number of scans, the higher the refresh rate, and the better the stability of the displayed image (picture). The lower the refresh rate, the more flickering and jittering the image, and the faster the eyestrain. Under the high refresh rate of the LED display, the captured image is stable, has no ripple black screen, clear image edges, and accurately restores the real information of the image.
5. Natural color reproduction
Adopt the world’s leading point-by-point correction technology and the principle of LED lighting to completely retain the authenticity of the color, avoid color loss and deviation caused by other display technologies such as the material of backlight projection and the light running path, and achieve true color reproduction.
6. Three-dimensional visual experience
When the customer chooses to use the 3D playback mode, the video wall will present shocking high-definition images. Whether it is live TV, exhibition display, or digital advertising, it can vividly interpret the wonderful vision, allowing the audience to enjoy an extraordinary visual experience.
Advantages of fine pitch displays
Because the small-pitch LED display is essentially a transformation of the ordinary LED display, therefore, the advantages of the above LED display, the small-pitch display has all the advantages, and there are other advantages.
1. Clearer picture
Ordinary LED display screens have a relatively large spacing, so if you look a little closer, the screen will have obvious graininess, and you can see small squares one by one, so the picture quality will also become blurred, and most of them are small. Spacing, within a distance of 1 meter, you can still see a clear picture, so many close monitoring rooms or conference rooms will use such products.
2. Thinner cabinet
Ordinary LED displays use iron boxes, while small spacing usually uses thinner and lighter die-cast aluminum cabinets. Therefore, whether it is transportation or disassembly, it is much simpler than bulky iron boxes. Generally, small spacing The weight of the cabinet is only 8kg, while the weight of the general simple box is 16.09KG; the weight of the outdoor waterproof box is 20 kg.
From this weight, even a thin girl can lift the small-pitch cabinet with one hand. However, even if it is a lighter LED simple cabinet, it may not be able to be lifted with one hand by a boy with an average physique. Not to mention the heavier outdoor waterproof cabinet.
3. Dismantling more aspects
The small-pitch LED display can be in the form of front maintenance. If there is damage to the LED module in a certain part, a single person can directly disassemble the damaged module through the front maintenance tool, and then install the new module. Replace it again.
However, if it is an ordinary LED display, when dismantling it, many people are needed to help, especially the display that is placed at a certain height. unnecessary accident.
4. Cob package
Cob packaging technology can be used for small spacing, so that the lamp beads and the chip are wrapped, so that the service life will be greatly extended, and it also avoids the damage or falling off of the lamp beads caused by the collision of the lamp beads.
In addition, the cob package reduces the gap between individual lamp beads., making it break through the limit of 1.0 mm and develop to a smaller millimeter. traditional LED displays generally do not undergo cob packaging.
From the above points, does the small pitch completely outperform the ordinary LED display? In fact, it is not. Because the ordinary LED display has many advantages that cannot be achieved by the small pitch.
The price of ordinary LED display is cheaper, mainly because the materials and technology used are different, so under the same model, the price of ordinary LED display will be cheaper
Small-pitch LED displays are only suitable for indoor use, and cannot be used or deal with various extreme outdoor weather. Therefore, the small-pitch LED displays we see are placed in monitoring rooms, conference rooms or shopping malls, and basically cannot be seen outdoors. small-pitch display.
3. Watch from a distance
Small spacing is only suitable for viewing at a relatively close distance. If the distance is too far, the effect will be poor. Although there are also products such as P5 and P6 manufactured by manufacturers that claim to be used at a longer viewing distance, the industry usually It is believed that the small-pitch display should be less than or equal to 2mm, so the gimmick of this product is greater than its actual content.
From the above information, we can conclude that each product has its strengths and weaknesses, and there is no saying which one is better. For example, if a car is produced, then it can be said that motorcycles and bicycles are not good. Obviously, it is the same with no comparability.
