1. The influence of the production process on the product
[LED advertising screen] How the production process of the product determines the anti-fatigue performance. The anti-fatigue performance of the modules produced by the inferior three-proof treatment process is difficult to guarantee. When the temperature and humidity change, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the protective performance.
Therefore, the production process of [LED advertising screen] is also a key factor in determining the life of the display screen. The production processes involved in the production of the display screen include: component storage and pretreatment process, furnace welding process, three-proof treatment process, waterproof sealing process, etc. The effectiveness of the process is related to the selection and ratio of materials, parameter control and the quality of operators. For most LED display manufacturers, the accumulation of experience is very important. A factory with many years of experience will control the production process more effectively. .
2. The influence of LED light source device performance
LED lamp bead devices are the most critical and life-related components of advertising screens. For LED lamp beads, the following indicators are mainly: attenuation characteristics, waterproof and vapor permeability characteristics, and anti-ultraviolet performance. If the LED advertising screen manufacturer fails to evaluate the performance of the LED lamp bead, it will be applied to the advertising screen, which will lead to a large number of quality accidents and seriously affect the life of the LED advertising screen.
3. Influence of supporting parts
In addition to the LED lamp bead light source, the LED advertising screen also uses many other supporting components, such as circuit boards, plastic housings, switching power supplies, connectors, chassis, etc., any quality problem of any component may lead to The life of the screen is reduced. Therefore, the life of the advertising screen is determined by the life of the key component with the shortest life. For example, LEDs, switching power supplies, and metal casings are all selected according to the 8-year standard, and the protective process performance of the circuit board can only support its work for 3 years. After 3 years, it will be damaged due to rust, so we can only get a piece for 3 years. life span of the display.
4. The influence of the working environment of the display screen
Due to different uses, the working conditions of advertising screens vary widely. In terms of the environment, the indoor temperature difference is small, without the influence of rain, snow and ultraviolet rays; the outdoor temperature difference can reach up to 70 degrees, plus wind, sun and rain. The harsh environment will aggravate the aging of the display, and the working environment is an important factor affecting the life of the display.
In a certain sense, the working environment of the LED advertising screen determines its lifespan. The life of an LED is usually defined as the time when the luminous intensity decays to 50% of the initial value. As a semiconductor material, LEDs are often said to have a lifespan of 100,000 hours, but that is an evaluation under ideal conditions. However, it cannot be achieved in actual use.
The life of the LED lamp beads determines the life of the [LED advertising screen] The life of the advertising screen does not mean that the life of the LED lamp bead is equal to the life of the advertising screen. When the advertising screen is working, not every LED is working at full load all the time. When the display screen is playing video programs normally, the lifespan of the [LED advertising screen] should be about 8 times that of the LED lamp beads. When the LED lamp bead works under the condition of low current, the lifespan can be longer.
