(1)Introduction to the Smart Exhibition Hall

The digital exhibition hall is a very useful means to show the strength of the company, and it can also be said to be a window of the company to the outside world. The traditional way of showroom display is to put products and business on the booth for the public to appreciate.In addition, a large number of personnel are required to explain. This method not only wastes a lot of financial and material resources, but also consumes manpower, giving people a monotonous feeling. It does not make a special impression, the audience is not interested, and the promotion effect cannot be achieved.

Multimedia digital exhibition hall is a technology exhibition venue, which integrates projection video, interactive technology, virtual reality, etc. in one exhibition hall, bringing viewers an immersive interactive viewing experience.

At present, more and more companies combine multimedia digital technology with exhibition halls, changing the traditional method of corporate exhibition hall display, and combining corporate culture with new technologies in multimedia, allowing companies to show a more comprehensive and in-depth interpretation of the core of corporate culture. content to help companies improve their corporate image.

As an important venue for the company to display its brand image and products, the corporate exhibition hall has been paid more and more attention by many corporate leaders in recent years, especially some companies that attach more importance to brand image and promotion, often plan space within the company,to plan A personalized showroom to display various information.

We know that traditional exhibition halls are static and lack interaction. Today's digital exhibition halls have rich display methods and introduce high-definition display devices to enhance the interaction of the audience, making them more interesting and artistic. The modern exhibition hall uses multimedia large-screen display technology, attracts visitors with various innovative and conceptual display methods, and completes the digital appearance of human-computer interaction.

The modern exhibition hall combines the concept of LED display, special-shaped display, holographic image and virtual reality and other display technologies, so that the digital exhibition hall has a sense of technology, interactivity and interest, and also makes the display content more intuitive and colorful. For example, the corporate exhibition hall can gain the trust of customers by optimizing the corporate image and focusing on displaying corporate products, allowing customers to understand the company's culture, products and services. It can also be used as a place for customers to visit, watch, communicate and negotiate. Therefore, in recent years, it has become an inevitable trend for enterprises to build their own exhibition halls.

People can use gesture operations to complete the manipulation of the interactive multimedia screen, and the gestures can be customized and programmed into the program of the interactive multimedia screen.

Since the COVID-19 pandemic, many small and medium-sized real estate companies have faced closures and shutdowns.
Large real estate companies are seeking new models for development, and global real estate companies have attracted a new round of real estate competition, which also makes various real estate marketing models emerge in an endless stream in the market.
Various modern visualization, informatization and intelligent publicity and display platforms have been widely operated in the real estate industry.

In such a fiercely competitive real estate industry, the sales office serves as the carrier of real estate image, customer experience center, real estate image display, sales completion and other functions. Therefore, building a sales office with beautiful appearance, fashionable atmosphere and highly concentrated internal functions has become the primary task of real estate competition. In order to better stay close to life and the development of modern society, when designing a sales office, the intelligent multimedia information display platform of the sales office must bear the brunt.

Choosing a good multimedia information display platform for the sales office can create a unique and favorable environment for customers to buy a house, thereby better promoting the promotion of real estate and establishing the brand image of the developer.

Recently, a real estate decided to build 2 sets of modern, information-based and intelligent multimedia information display platforms in the sales office to improve the hardware and software equipment of the sales office and enhance the publicity and display system of the sales office. In the early stage of the project, the real estate sales office screened the commercial display manufacturers from all over the world and built 2 sets of multimedia information display system platforms.

Professional engineers conducted on-site investigations and measurements, and tailored a set of 3×3 splicing multimedia information display system platforms with nine 3.5mm 46-inch LCD display units, and a set of P2.0 LED display screen on their site and user needs. The display screen creates a set of intelligent information interactive display system platform for the display unit.

In this project, the 46-inch LCD display has an LCD splicing screen with a 3.5mm ultra-narrow edge splicing gap, an industrial-grade panel, 4K ultra-high-definition display technology, LED backlight technology, 3D image noise reduction technology, and 178° ultra-wide viewing angle extension technology. Let the whole system run stably for a long time, so that the picture is not distorted, clear and delicate.

The other set uses a P2.0 LED display, which has a high-gray and high-brush driver chip. It displays bright colors and soft light. It will not cause dizziness when viewed at close range. The almost imperceptible full-screen seamless effect maintains the continuity of the picture, and the use of point-by-point correction technology ensures the consistency of the picture brightness. Similarly, this set of LED display screens can adjust the color temperature of the screen in a wide range, which perfectly meets the requirements of the virtual simulation platform with high color accuracy requirements and ensures the accurate restoration of images.

What is LED splicing screen?

LED splicing screen is also called electronic splicing screen. It is different from LCD splicing screen. It is mainly composed of LED dot matrix and led pc panel, and then displays the text and pictures you want to show by turning on or off the LED lights of various colors. Or video etc. The LED splicing screen has higher brightness, presents a larger picture, and has a strong three-dimensional sense. It can present a clear picture both indoors and outdoors, so it is more and more used by various industries.

Four connection forms of LED display:

1. The whole screen of the LED display is assembled in series: the LED1-n in the general simple series connection method are connected end to end, and the current flowing through the LED display is equal when it is working. The other is the improved way of series connection with bypass as 1.1.

2. The LED display screen is assembled in parallel for the entire screen: one is a simple parallel form, and the other is an independent matching parallel form. The LED1-n in the simple parallel mode are connected in parallel end to end, and the voltages on each LED are equal during operation.

This kind of reliability is not high, but it also adopts the parallel form of independent matching to solve this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no impact on other work in case of failure, and large differences in matching.

3. LED display cross array assembly method: The cross array shape is mainly proposed to improve the reliability of the LED display and reduce the failure rate.

4. Hybrid assembly method of LED display screen: the advantages of parallel connection and series connection mentioned in the appeal are comprehensive. It also includes 2 kinds. One is the hybrid mode of first serial and then parallel, and the other is the hybrid mode of first parallel and then serial.

The above four LED display assembly and connection methods have their own advantages and disadvantages, and the most suitable LED display connection method can be selected according to different applications. Many engineers and technicians tend to ignore this point, which leads to various connection failures in the LED display, which ultimately affects product quality and reduces user trust. It can be seen that the assembly of the LED display screen, the details determine the success or failure!

LED display splicing precautions:

1. The filling factor should be high:

And the LED display screen is composed of discrete pixels, and there are obvious non-luminous black areas between the pixels, so when viewed from a close distance, the picture is not coherent and incomplete, and the uneven brightness produces a grainy feeling. If the light source is limited In a very small pixel surface area, when the brightness of a single pixel is several times or even more than ten times the brightness of the entire screen, it will cause a more serious glare.

The TCO'99 standard recognized by the flat panel display industry stipulates that the fill factor of the display device should not be less than 50%. For LED displays with the same dot spacing, the smaller the fill factor is more attenuated than the larger one, so the shooting distance needs to be increased; and if the low-pass filter passband of the system is 4MHZ, the high-frequency attenuation characteristic is 12dp times. frequency range.

Then the shooting distance with a fill factor of 25% is attenuated by 1.15dp more than a fill factor of 50%, and the shooting distance needs to be increased by about 10%. Therefore, the higher the fill factor, the wider the viewing angle of the display screen and the more ideal color mixing effect. ; Therefore, it also solves the problem of glare, and also creates conditions for properly increasing the brightness of the entire screen to obtain better effects.

2. The dot spacing of the LCD splicing screen should be small:

The dot pitch is the distance between the LED display screen adjacent to the pixel center point. The smaller the dot pitch, the more pixels per unit area, the higher the resolution, and the closer the shooting distance can be; therefore, in order to achieve an excellent display effect, it is necessary to pay attention to the difference between the resolution of the signal source and the dot pitch. And try to achieve the same resolution, point-to-point display has been achieved, so as to achieve the best display effect.

3. Adjustment status of color temperature

Color temperature is the temperature determined by comparing the shape of the emission spectrum of the emitter to the shape of the best fit black body emission spectrum. For example: when the studio uses the LED display as the background to display the picture, its color temperature should be consistent with the color temperature of the indoor lighting in the studio, so that accurate color reproduction can be obtained during shooting; therefore, as long as the LED display is adjusted to the corresponding color temperature, Satisfactory shooting results can be obtained.

4. Appropriate use environment:

As an integrated electronic product, LED display is mainly composed of control panel, light-emitting device, switching power supply and other components equipped with electronic components; and the stability and life of these components are closely related to the environment in which they are used. . When the actual working temperature exceeds the specified use range of the product, it will not only shorten the service life, but also seriously damage the product itself.

And if you work in a dusty environment, the deposition of dust will also affect the heat dissipation of electronic components, causing the temperature of the components to rise, resulting in a stable thermal drop or even leakage. In more serious cases It will cause the equipment to burn out and cause huge economic losses, so the use environment should also be the "top priority" of attention.

Expand all four led display connection forms:

1. The whole screen of the LED display is assembled in series: the LED1-n in the general simple series connection method are connected end to end, and the current flowing through the LED display is equal when it is working. The other is the improved way of series connection with bypass as 1.1.

2. The LED display screen is assembled in parallel for the entire screen: one is a simple parallel form, and the other is an independent matching parallel form. The LED1-n in the simple parallel mode are connected in parallel end to end, and the voltages on each LED are equal during operation.

This kind of reliability is not high, but it also adopts the parallel form of independent matching to solve this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no impact on other work in case of failure, and large differences in matching.

3. LED display cross array assembly method: The cross array shape is mainly proposed to improve the reliability of the LED display and reduce the failure rate.

4. Hybrid assembly method of LED display screen: the advantages of parallel connection and series connection mentioned in the appeal are comprehensive. It also includes 2 kinds. One is the hybrid mode of first serial and then parallel, and the other is the hybrid mode of first parallel and then serial.

The above four LED display assembly and connection methods have their own advantages and disadvantages, and the most suitable LED display connection method can be selected according to different applications.

Precautions:

1. Switch sequence:

When the screen is turned on: first power on, then turn on the screen. When the screen is turned off: turn off the screen first, then shut down
(Turn off the computer first without turning off the display screen, which will cause bright spots on the screen body, and the LEDs will burn the lamps, which will cause serious consequences.)

2. The time interval between switching on and off the screen should be more than 5 minutes.

3. After the computer enters the engineering control software, the screen can be powered on.

4. Avoid opening the screen in a completely white screen state, because the inrush current of the system is the largest at this time. 5. Avoid opening the screen in an out-of-control state, because the inrush current of the system is the largest at this time.

5. When the ambient temperature is too high or the heat dissipation conditions are not good, the LED lighting should be careful not to open the screen for a long time.

6. When a part of the electronic display screen appears very bright, you should pay attention to closing the screen in time. In this state, it is not suitable to open the screen for a long time.

7. The power switch of the display screen often trips, and the screen body should be checked or the power switch should be replaced in time.

8. Regularly check the firmness of the connection. If there is any looseness, pay attention to timely adjustment, re-reinforce or update the hanger.

9. According to the environment of the large-screen display screen and the control part, avoid insect bites, and place anti-rat medicine if necessary.
