In today's increasingly developed digital information dissemination era, LED display screen by virtue of its high brightness, high definition, bright colours and flexible splicing and many other advantages, widely used in commercial advertising, stage performances, sports events, traffic instructions, monitoring centres and other areas. However, in the face of a wide range of LED display products on the market, the price difference is large, so that many consumers and buyers in the purchase of confused.LCF editor will provide you with a detailed analysis of the main factors of the LED display offer, to help you in the purchase process to make informed decisions.

(A) display size

Size is the most intuitive factor to determine the price of LED display. Generally speaking, the larger the display area, the greater the number of LED lamp beads required, the corresponding cost of raw materials, manufacturing costs and installation and commissioning costs will increase significantly. For example, a 50 square metre large LED display for outdoor advertising, the price may be as high as hundreds of thousands of yuan, while a few square metres of indoor display LED display, the price may be within tens of thousands of yuan.

(B) Pixel Pitch

Pixel pitch (Pitch) refers to the distance between the centres of two adjacent LED lamp beads, usually in millimetres (mm). The smaller the pixel pitch, the greater the number of lamp beads per unit area, the higher the resolution of the display, the clearer and more detailed the image display. However, a smaller pixel pitch means higher production costs, as more sophisticated manufacturing processes and higher quality LED beads are required. Common pixel pitches include P1.2, P1.5, P1.667, P1.875, P2, P2.5, P3, P4, P5, P6, P8, P10 and so on. P1.2 and P10, for example, P1.2 LED display is suitable for the high requirements of the picture quality of the close viewing scenes, such as high-end conference rooms, studios, etc., its price is relatively expensive; and P10 display is commonly used in outdoor long-distance viewing of advertising screen, the price is more affordable. Generally speaking, the pixel pitch is reduced by one grade each, the price may be raised by 30% -50% or even higher.

(C) LED bead quality

LED bead is the core component of LED display, its quality directly affects the display brightness, colour reproduction, stability and service life and other key performance indicators. High-quality LED lamp beads usually have higher luminous efficiency, more accurate colour performance and better heat dissipation performance, but the cost is also relatively high. For example, the use of imported well-known brand chip package LED lamp beads, its price is much more expensive than ordinary domestic lamp beads. In some of the harsh requirements of the picture quality of the professional application of the scene, such as broadcasting and television studio, cinema, etc., often use high-quality LED lamp beads, which also makes the offer of such displays rose sharply.

(D) display brightness

Brightness is an important parameter to measure the visual effect of LED display in different ambient light conditions, the unit is nits (nit). High brightness display can still clearly display image information under strong light, suitable for outdoor environment or strong light indoor places; while low brightness display is more suitable for indoor light environment, such as meeting rooms, exhibition halls and so on. In order to achieve higher brightness, it is necessary to increase the power of LED lamp beads or adopt special optical design, which will undoubtedly increase the cost. Generally speaking, the brightness of outdoor full-colour LED display is required to be 5000-8000nit or even higher, while the brightness of indoor display is usually between 800-1500nit. The higher the brightness of the display, the price will increase accordingly.

(E) Refresh rate

Refresh rate refers to the number of times per second the LED display updates the image, the unit is hertz (Hz). High refresh rate can effectively reduce the image of flicker and shadow phenomenon, so that the dynamic picture is more smooth and clear, especially in the playback of high-speed sports video or live sports events, the advantages of high refresh rate is more obvious. Higher refresh rate requires more advanced driver chip and control technology support, which leads to higher costs. Common LED display refresh rate of 3840Hz, 3000Hz, 1920Hz, 1200Hz, etc., the higher the refresh rate, the higher the price will usually be. For example, a high-end LED display with a refresh rate of 3840Hz, its price may be 20%-30% higher than the same size and pixel pitch display with 1200Hz.

(F) protection level

Protection level (IP rating) is used to measure the protection ability of LED display against dust, water and intrusion of foreign objects. For outdoor use of the display, due to the complexity of the natural environment, such as rain, sand, dust, ultraviolet rays, etc., need to have a high level of protection, generally required to achieve IP65 or above; and indoor display protection requirements are relatively low, usually IP30-IP50. in order to achieve a higher level of protection, display in the shell design, sealing treatment, material selection, etc. need to take special measures. To achieve a higher level of protection, the display in the shell design, sealing treatment, material selection and other aspects need to take special measures, which will increase production costs. The higher the protection level of the LED display, the higher the price accordingly.

(G) control system

The control system of LED display is responsible for receiving and processing the input video signal and accurately distributing it to each LED lamp bead for display. An advanced control system should have a strong signal processing capability, high stability and rich features, such as support for a variety of video formats input, with grey scale correction, colour management, brightness adjustment and other functions. Different brands and models of control systems have large differences in performance and price. High-end control systems can provide more accurate colour control and higher refresh rate support, but they are also more expensive. For example, the price of some professional broadcast-grade LED display control systems may account for 10-20% of the cost of the entire display system.

(H) installation and maintenance

LED display is installed in a variety of ways, including wall-mounted, column, hanging, embedded, etc. Different installation methods have different requirements for installation structure and accessories, and the installation cost will be different. In addition, the display needs regular maintenance in the process of use, such as cleaning the screen, checking the line connection, replacing the damaged lamp beads, and so on. Some large outdoor displays are difficult to maintain due to their high installation position, requiring professional maintenance equipment and personnel, which will also increase the maintenance cost in the later stage. Therefore, the installation and maintenance cost is also one of the important factors affecting the LED display offer. In some complex installation environments or projects that require long-term maintenance services, installation and maintenance costs may account for 15-25% of the total offer.
