The cultural and tourism market remained booming in 2023. Affected by the continuous high temperature this summer, night tours have become the top choice for contemporary tourists. Tourism keywords such as "night tour", "night climbing", and "midnight snack" frequently made it to the hot search lists. According to the data from Lvmama, since July, the platform's ticket orders for night tour products have increased by 135% month-on-month, and the number of outbound tourists has increased by 67% month-on-month. Night tours like the Huangpu River Night Cruise, the Night Cruise on the Ancient Canal in Suzhou, the Night Cruise on Qiandao Lake, the Ever-bright City of the Tang Dynasty, and the Pearl River Night Cruise are all popular choices for tourists' night tours.  

The cultural and tourism market remained booming in 2023. Affected by the continuous high temperature in the summer of this year, night tours have already become the top choice for contemporary tourists. Tourism keywords such as "night tour", "night climbing", "midnight snack" and so on have frequently appeared on the hot search lists. According to the data from Lvmama, since July, the platform's ticket orders for night tour products have increased by 135% month-on-month, and the number of outbound tourists has increased by 67% month-on-month. Night tours such as the Huangpu River Night Cruise, the Night Cruise on the Ancient Canal in Suzhou, the Night Cruise on Qiandao Lake, the Ever-bright City of the Tang Dynasty, the Pearl River Night Cruise, etc., are all popular choices for tourists' night tours. 1.jpg 2.jpg Many scenic areas have created a variety of characteristic night tour themed activities to activate the summer vacation market and enrich the tourists' experience. The night tour consumption in various places shows a prosperous situation in both supply and demand. So, how should we choose the hardware equipment for the projection light show, which is the core of night tours? As the two most important technologies for distinguishing commercial projectors, how should we choose between "DLP" and "LCD"? First of all, let's talk about the differences between "DLP" and "LCD": I. Different Meanings 1. DLP: Digital Light Processing. That is to say, this technology needs to process the image signal digitally first, and then project the light. 2. LCD: It is the product of combining liquid crystal display technology and projection technology.

II. Different Principles 1. DLP: The projection principle of DLP (Digital Light Processing) is to reflect the light source onto a tiny DMD (Digital Micromirror Device) chip through a tiny mirror. Each pixel is controlled by a controllable tiny mirror, and these mirrors can be controlled by turning on and off the electrical signals, thus changing the reflection angle and forming an image. 2. LCD: It uses three liquid crystal panels of red, green, and blue respectively as the control layers for red, green, and blue light. The white light emitted by the light source converges onto the color separation prism group after passing through the lens group. The red light is separated first and projected onto the red liquid crystal panel. The image information recorded on the liquid crystal panel, which is represented by transparency, is projected to generate the red light information in the image.

III. Different Characteristics 1. DLP: It is an original solution that uses optical semiconductors to generate digital multi-light source displays. It is a highly reliable all-digital display technology that can provide the best image effects in various products. 2. LCD: It makes use of the electro-optic effect of liquid crystals. By controlling the transmittance and reflectance of the liquid crystal units through circuits, it can produce beautiful images with different grayscale levels and up to 16.7 million colors.

In conclusion, both DLP and LCD have their own advantages and disadvantages. However, in the practical application of cultural and tourism projects, DLP has its unique advantages. In traditional LCD projectors, the liquid crystal molecules in the LCD panel, which is the core component, are prone to decomposition in a high-temperature environment, resulting in a decline in image quality. The core component of DLP chip projection, the DMD chip, adopts reflective technology. It absorbs less heat energy during operation, and the components are small in size and light in weight. Therefore, DLP projection has the characteristics of being more resistant to high temperatures and more portable. This is particularly important in outdoor projects.

At present, the cultural and tourism industry is undergoing rapid changes in line with the times. The birth of Diheng's "Light and Shadow +" combines immersive technology, interactive technology, content customization and other technologies with the traditional cultural and tourism industry, providing assistance in creating diverse cultural and tourism experiences that are in line with local characteristics. It breathes new life into scenic spots and boosts the urban night-time economy. As the main equipment for cultural and tourism night tours, laser projectors must also keep up with the development of the cultural and tourism industry, and DLP technology is one of the core elements among them.

In the face of such a rapidly changing cultural and tourism market, projector manufacturers must carry out equipment innovation. Recently, Diheng China has launched two high-lumen DLP laser projectors, DU22K and DU26K, specifically designed for cultural and tourism night tours.

Diheng's DU22K and DU26K adopt DLP projection technology and support HSG color adjustment, enabling the projected images to restore their original colors. The dust-proof rating of IP5X is suitable for various outdoor sites. With a laser light source lifespan of up to 20,000 hours, it truly achieves both maintenance-free operation and long lifespan. With the full recovery of the tourism industry this year, cultural and tourism scenic spots across the country have entered the era of "Light and Shadow +". Various night tour projects such as light and shadow shows, water screen movies, building facade shows, etc., have emerged like mushrooms after rain. This also marks the official opening of a richer and more diverse tourism era. And the DLP technology, which has high image quality and high cost-effectiveness, is likely to become a new engine for the "Light and Shadow +" transformation in the cultural and tourism industry.
