As the main force in the field of large-screen splicing, DLP splicing large screens have been widely used in many fields. Moreover, with the gradual improvement of technology and the hot demand for large-screen vision, its application scope has become wider and the application environment has become more extensive, and the purchase and maintenance issues that come with it have become more complicated. In fact, as a high-investment product, the purchase and maintenance of large screens have always been a problem that troubles many ordinary users. How can we get value for money or even more value for money? Please listen to the editor slowly.


The main factors for the "short life" of DLP large screens

1. The collective airtightness is not good enough, and dust becomes a fatal terminator

Light source is the core element of large-screen display, and the service life of the light source directly affects the service life of the large screen. However, DLP large screens have long been criticized for their short light source life. The short life of the light source not only directly leads to high-intensity maintenance work such as frequent replacement of the light source, but also opens the door to dust, which has become the most troublesome problem for many users.

Generally speaking, if there is dust on the optical path, the brightness of the projector will be greatly reduced, the image will be blurred, and the display effect will be seriously affected. This is obviously contrary to the current concept of large-screen display for high-definition display. A large screen without high-definition image display will lose its meaning of existence. At the same time, dust will hinder the heat dissipation performance of the projector's optical components and cause damage to the optical components, so regular and comprehensive treatment is essential. Judging from the current design of large screens, cleaning is a professional operation that ordinary users cannot complete by themselves, which makes the already high cost of large-screen application go up a level. In addition, from the perspective of historical DLP large-screen applications, DLP large screens have been widely used in the fields of electricity, meteorology, command centers, etc., and require continuous long-term use. Interruption of use may cause irreparable losses. Frequent cleaning and maintenance will make the DLP large screen lose its value.

2. Large amounts of heat dissipation make ventilation holes a "double-edged sword"

DLP splicing large screen is composed of multiple DLP splicing units, which will generate a lot of heat after long-term operation. If the heat dissipation performance of the product is not good, it will cause damage to the internal components and the large screen will be "either dead or injured". For many users who choose to purchase products, heat dissipation performance is one of the important factors to consider.

The large amount of heat generated by the DLP splicing large screen is directly taken away by the vents, and at the same time, impurities in the air will also enter the large screen. The long-term accumulation of dirt and impurities directly leads to the slowdown of the cooling fan speed of the large screen optical device, affecting the internal heat dissipation of the large screen optical device. The accumulation of heat will cause direct damage to the internal components, which will affect the use of the large screen in mild cases and make the large screen "die". Therefore, the majority of users must test the heat dissipation performance of the device when purchasing products to ensure normal use in the future. Moreover, in daily use, the large screen should be placed in a ventilated place and the vents should be cleaned regularly to ensure the normal use of the large screen.

3. Temperature directly affects the use of outdoor DLP large screens

Temperature has a serious impact on the use of DLP large screens. Generally speaking, when the temperature is below minus 30 degrees Celsius, the large screen should be suspended to avoid irreparable damage. Therefore, when purchasing large screen products, users should pay attention to the normal operating temperature of the large screen and consider the purchase in full consideration of their own use environment.

For large screens used in complex environments, especially those with low temperatures, users should monitor the temperature of the working environment in a timely manner to ensure safe use. For now, for those that need to be used normally in extreme environments, you can choose to install air conditioners in the chassis to ensure the normal working temperature of the large screen itself. The temperature limitation has caused the workload of maintenance personnel when used in extreme environments, which has greatly increased the complexity of use.

4. Wrong operation due to sudden power failure will seriously damage the large screen

As a professional display device, most users are not familiar with the details of its operation. Many people directly cut off the power of the projector after turning off the optical device of the large screen, but they don’t know that this will seriously affect the service life of the large screen. Users’ understanding of the product is necessarily limited. Therefore, when choosing a large screen product, users should pay attention to the intelligent protection of the product to facilitate future applications.

Juyang VLED light source leads the new trend of easy-to-use DLP large screen

As a traditional DLP large-screen manufacturer, Juyang has always adhered to the development concept of being based on the market and taking user needs as the basis of its research and development. In response to the current bottleneck of DLP applications, Juyang has timely launched a new VLED light source to effectively solve practical problems and achieve truly simple applications.

Eliminate the stubborn problem of dust and reduce the maintenance burden

Juyang VLED light source is an ultra-long-life LED light source with a service life of up to 60,000 hours. It has solved the historical problem of frequent replacement of DLP large-screen light sources, reduced the cost of use, and reduced maintenance work. The fixed use of the light source has greatly improved the airtightness of the DLP large screen, and Juyang products also use Juyang's unique optical-mechanical modular airtight dustproof design. The special metal material shell is equipped with an airtight dustproof ring to fundamentally prevent the entry of dust and achieve both symptomatic and root treatment. In order to completely meet the dustproof requirements, the optical-mechanical overall of Juyang VLED light source meets the 5-level dustproof standard, rather than the traditional optical path components. The improvement of the product's own immunity effectively facilitates the user's daily use.

Intelligent temperature control facilitates applications in extreme environments

Compared with traditional products, Juyang VLED has uniquely designed two CPU chips in the optical engine. The newly added CPU is responsible for communication with the control unit, temperature monitoring, fan speed and other control functions, so that the main CPU can concentrate on image processing. The improvement of the product's own performance detection capabilities effectively avoids serious damage caused by negligence of maintenance personnel, which is of great significance, especially for monitoring sites with continuous work.

Redundant hot backup power supply, more user-friendly design

In response to the common negligence of users to directly cut off the power supply of the projector after turning off the large-screen optical equipment, Juyang VLED light source splicing unit is innovatively equipped with redundant hot backup power supply to provide a long-lasting and stable power supply for the unit, reduce the failure rate, and avoid sudden power outages that damage the equipment and affect the normal operation of the unit. This measure effectively avoids unnecessary losses caused by blind operations by users and brings great convenience to users' actual applications.
