3. The LED full-color display screen has the closest relationship with our users, so it is also necessary to do a good job in cleaning and maintenance.Long exposure to the outdoor environment wind, sun, dust and other easy to dirty, a period of time down, the screen must be a piece of dust, which needs to be cleaned in time to prevent dust for a long time to wrap the surface affect the viewing effect.
4, the power supply is required to be stable, and the grounding protection is good, do not use in bad natural conditions, especially under strong thunder and lightning weather.
5, the LED display needs to check regularly whether it can work normally, whether the line is damaged, if it does not work, it needs to be replaced in time, and the line damage should be repaired or replaced in time.
6, do not play for a long time in all white, all red, all green, all blue and other bright screen, so as not to cause excessive current, power line heating is too large, LED light damage, affect the display life.
7, do not arbitrarily disassemble, splicing screen body!The LED full-color display screen is the most closely related to our users, so it is very necessary to do a good job in cleaning and maintenance.
8, the LED display screen should be regularly checked whether the normal work, the line is not damaged, if not work to be replaced in time, the line is damaged to be repaired or replaced in time.The internal circuit of the LED display screen is forbidden to be touched by non-professionals to avoid electric shock or damage to the circuit.If there is a problem, you can contact Henan Liade general distributor Zhengzhou Hengyuan photoelectric please our professionals for maintenance.
Let's take a look How to solve two common problems with LED displays?
How to install the LED display?
LED screen business facing more challenges do you know?
How to identify the quality of outdoor LED advertising screen?
Outdoor LED advertising screen is composed of a lot of LED beads, LED beads as the display screen cost and the largest amount of components, so it plays a decisive role in the quality of LED display.Bead lamp is the most important component of outdoor LED advertising screen, and also the most used core device, which directly affects the use effect of outdoor LED advertising screen.
First, look at the bracket
In general, the support is silver-plated copper bracket. The advantage of silver-plated copper bracket is fast heat dissipation, which can better heat the lamp bead and has small resistance.Some businesses on the market will use ceramic bracket to replace the silver-plated copper bracket, ceramic bracket thermal conductivity is very excellent.
Two, look at the brightness
How many LMS (lumens) can your bulb reach? Lm is a measure of the brightness of the bulb.
Three, see whether the light is uniform, the color is consistent
Good quality beads shine evenly and have a consistent color.The poor quality of the lamp bead will appear a lamp bead brightness bright, a lamp bead dark phenomenon, luminous color mess is not unified, there will be obvious dark area.
Four, look at the chip and chip size, chip is the determinant of the quality of the lamp bead
In general, the larger the chip, the stronger the stability, the higher the brightness, the better the heat dissipation.This is the most important, because the chip directly determines the color rendering index, brightness, anti-attenuation degree.
Five, look at the glue
Generally good lamp beads will use imported glue. The encapsulated LED lamp beads will not be deformed by hand. The glue with low quality will be deformed or even cracked as soon as it is pressed.
Six, look at the packaging process
High quality LED lamp bead has uniform color and good gel consistency.This is inseparable from good machinery and equipment, production machinery and equipment is the key factor, good equipment can ensure the stability and consistency of the product in each scheme, to ensure product yield.
Through the above narrative I believe you have a general understanding of the quality of outdoor LED advertising screen, you can consult in the purchase of outdoor LED advertising screen when there are any problems.
A large number of raw material prices, LED screen business facing more challenges do you know?
As we entered the end of the first quarter of 2021, the rise of materials did not ease. On the contrary, unexpected events such as "the giant ship from Taiwan ran aground in the Suez Canal" and "the United States started printing US dollars" further triggered the price rise of a large number of raw materials.It is understood that the recent price of raw materials, including chips, PCB and so on, continues to rise dramatically and supply is tight, which brings more challenges to LED screen enterprises.
At the same time, in the market we are busy to grab goods, stockpiling goods, waiting for the first round of the peak season market detonated, looking forward to this round of stockpiling action, can in the next few months on the market to "make money";On the other hand, the market consumption is still sluggish and weak, especially for many offline dealer channels, the consumer demand has not fully recovered, but strangely, everyone is not worried about this situation, and seems to be waiting for and expecting the next market outbreak.
This phenomenon, on the one hand, is that everyone is generally aware that this round of raw materials rise cycle has not ended, will not end in the short term, so has maintained a high degree of confidence and investment momentum;Second, we are full of expectations for the next Micro/Mini LED and other new products as well as the expected market consumption such as cultural tourism industry and market segments. After all, after experiencing last year's consumption depression, the rebound of rigid demand and the demand for new ones inspire the LED screen enterprises to hide their fighting spirit and enthusiasm for several months.In addition, the current differentiation of products and applications, also bring the possibility of premium LED display.
In response to soaring raw material prices, LED panel companies have been alleviating cost pressure by optimizing the material supply side on the one hand and improving production mechanization on the other hand to improve efficiency and reduce costs.The search for a "differentiated premium element" has become a strategic means for screen companies to recapture pricing power, such as the big conference screen market during the epidemic.
Through the increase of intelligence, storage, integration and other functional differences, has become a big magic weapon for LED screen enterprises curve overtaking.At present, including the application of intelligent LED transparent screen, intelligent LED creative business display, LED intelligent landscape lighting and other scenes, compared with the traditional LED display products, can better meet the needs of the market personality and differentiation.At present, more and more LED screen companies are exploring differentiation through design, brand, subdivision, engineering retail, youth and technology, which brings more possibilities to their product premium.
In fact, the development of China's LED display industry at the current stage, product and service homogenization and price war has been exhausted, and to change this pattern, take the road of differentiation is inevitable.From a certain point of view, each different period of the industry dilemma, is a survival of the fittest, forcing the industry to get out of the old and innovation of the big shuffle, in the face of the current raw materials soaring, the same is true.If LED screen enterprises want to improve their ability to resist risks, they need to improve their production processes, operation and management, and increase the added value of their products.For example, some enterprises do intelligent display solutions, do personalized customization, under the premise of good enough product quality, even if the price rise, there are customers scrambling to place orders, then the impact of the price rise of raw materials on it will be greatly reduced.
China's LED display manufacturing industry used to rely on scale economy and quantity to win, but in the new era, LED screen enterprises need to consider more about how to improve the value of products?To win by quality, in order to occupy a dominant position in the changing market environment.
