Description

DISPLAY MODULE TECHNICAL FIELD The present disclosure relates to heat transfer modules. Moreover, the present disclosure relates to electronic displays. Furthermore, the present disclosure relates to electronic billboards. BACKGROUND Outdoor display screens have become increasingly popular in recent years due to their ability to attract attention and engage audiences. One of the most common uses of outdoor display screens is for advertising purposes. The outdoor display screens can be used to display dynamic and eye-catching content, such as videos, animations, and images, that can quickly grab the attention of people passing thereby. As a result, businesses and organizations can use the outdoor display screens to promote their products, services, or events to a large audience in a highly effective and engaging way. Typically, the outdoor display screens are located in high-traffic areas, such as shopping malls, airports, and busy city centres. Moreover, the outdoor display screens can also be used to provide information to the public, such as weather updates, news headlines, or event schedules. They can also be used for entertainment purposes, such as displaying live sports events or concerts. However, conventional outdoor display screens are vulnerable to weather conditions. The outdoor display screens are often exposed to harsh weather conditions such as rain, wind, snow, and extreme temperatures, which can damage or destroy the screens and other electronic components. This can result in costly repairs or replacements, and downtime. Typically, LED panels arranged in the outdoor display screen used in outdoor environments are extremely susceptible to high temperatures. Especially the display screens that are arranged in the direct sunlight. In direct sunlight, the surface temperature of an outdoor LED display screen can rise to more than 100°C, and internally, below the surface of the display screen, temperature can rise even higher. Overheating can cause failure or malfunction of the screen or components. Current solutions involve the use of outside air (such as natural air) to cool the LED panels. The use of outside air requires filters to avoid the ingress of dust and dirt. However, the filters have the disadvantage as they require frequently replacement. Moreover, to avoid the ingress of dust and dirt and use of filters, the compressors are used to provide the clean air. However, the use of compressor increases the cost of operation of the outdoor display screens and requires regular maintenance. Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks.
