1.1 Indoor Shops
Some indoor shops in shopping malls have large windows at the entrance of the shop to display product features or brand image. LED screens for indoor advertising are usually placed here to increase exposure and attract potential users to pass by. Such LED screens for indoor shops require high quality images and natural colours, as well as energy efficiency to reduce the cost of the shop. In addition, flexible LED screens are installed on top of different shelves in the shop to display product prices, promotions or other details. This indoor LED display has to be flexible in size with some curvature according to the design of the shelves.

1.2 Entertainment Venues
LED displays are widely used in bars, KTVs, nightclubs and other indoor entertainment venues. Bars and nightclubs are places that need different atmospheres to mobilise customers’ moods according to different themes; therefore, ceiling LED displays are needed to create a cheerful and exciting atmosphere in entertainment venues. In addition, indoor LED screens can be seen on the bars to display product information. Due to the high demand of customers for entertainment experience, entertainment venues prefer indoor LED displays that present high quality and smooth images.

1.3 Restaurants
Most restaurants have a large indoor LED display at the order counter to showcase dishes or promotional items. Indoor LED displays in restaurants require large size and high brightness to allow customers sitting at a distance to see what is on the display.

1.4 Hotel Lobby and Resort Hotel Lobby
Large indoor LED displays are located above the front desk to show the current occupancy of hotel rooms and announce the do’s and don’ts. In addition, LED screens are installed on the walls around the hotel lobby to display current events or promotions of the hotel and resort. In this case, the LED screens in the hotels and resorts need to be medium sized, energy efficient, and have clear and smooth images.

1.5 Indoor Arenas
Indoor arenas typically have a ring of LED fence displays around the venue to show advertisements or current events. In addition, the centre of the venue or the centre of the spectator area is usually equipped with a four-sided LED display to show the game, moments of the event or the reaction of the spectators. Indoor LED screens in stadiums require large sizes that can smoothly display high-quality video or images in real time to provide an immersive viewing experience for spectators.

1.6 Indoor advertising and film shooting
For some virtual scenes of film and advertisement shooting, the traditional way of using green screen as the background requires tedious post-production, which undoubtedly increases the production and time cost. However, as the advantages of LED screen in film and advertising shooting gradually emerge, more and more film and television companies prefer to produce LED display background rather than green screen for virtual scene shooting, in order to reduce post-processing costs. Virtual production LED wall requires large size, high brightness, high definition picture quality and natural colour to meet the high requirements of film and television production.

1.7 Churches
Some churches hold mass gathering activities on a regular basis. For large churches, LED screens need to be installed in front of the pulpit and around the church walls to display the activities and meetings so that the congregation sitting at the back can clearly understand the content and progress. In addition, some churches also host wedding events, requiring the church to be equipped with ceiling-mounted LED screens to create a festive atmosphere. Church LED screens are the same as the above scenarios, presenting high-quality images and saving energy.


1.8 Banks
Major banks have a large LED display above the business processing counter, which can show customers the current progress of business processing or broadcast information. Banks indoor LED screen is mainly used to display text, the requirements for picture quality is not strict.

1.9 Hospitals
The coverage of indoor LED display will be very high, because some hospitals in the United States, each functional area, such as registration area, nurses’ station, medicine collection area, etc., need an indoor LED screen to display patient-related information and make emergency announcements. LED screens used in hospitals are the same as those used in banks, which mainly display text and do not require high picture quality.

1.10 Schools
Compared to some profitable indoor places, school LED screens are mainly used for publicising and educating about events, causes or activities. Not only that, schools also hold large-scale events or organise large-scale conferences in indoor stadiums or auditoriums, requiring school managers to install LED screens with the same requirements as the indoor LEDs needed for indoor stadiums and churches mentioned above.

2. How to choose the size and resolution of indoor LED display?

2.1 Size: According to the size of the lecture theatre and the number of audience, choose the appropriate size and resolution. Generally speaking, a larger screen can provide a wider field of view and clearer content.
2.2 Resolution: The higher the resolution, the clearer the content displayed. Typically, the resolution should be at least HD (1280×720) or higher.
2.3 Brightness: The screen should be bright enough to ensure vibrant colours and details in a wide range of lighting conditions. Generally, a brightness of between 500-800 cd/m² is appropriate.

3. How to achieve high brightness and high contrast in indoor LED display?

First of all, when choosing LED display, you should focus on the quality of its light source and panel. Light source is one of the key factors to determine the brightness and contrast, choosing a high brightness and high contrast light source is conducive to improving the overall display effect.

At the same time, the quality of the panel also directly affects the performance of the display. A quality panel can provide better colour reproduction and contrast, making the picture more vivid and realistic. Therefore, when buying LED displays, choose brands and suppliers with good reputation and good word of mouth to ensure product quality. Such as Leyard, Unilumin, Absen, LEGIDATECH, Ledman and so on.

Next, adjust the brightness and contrast parameters of the display. Most LED displays provide brightness and contrast adjustment functions, and users can make appropriate adjustments according to actual needs. In the indoor environment, the brightness can be appropriately reduced to avoid over-brightness to the human eye stimulation.

While in the outdoor environment, the brightness should be increased appropriately to ensure the clarity of information conveyed. Contrast is also one of the important parameters, too low contrast will lead to blurring of the picture, while too high contrast will make the picture too exaggerated. By reasonably adjusting the brightness and contrast parameters, you can get a better display effect.

Finally, the reasonable use of lighting environment and background colour matching. When using LED display, the lighting environment and background colour matching are important factors affecting the brightness and contrast. If the surrounding environment is too bright, the brightness of the display needs to be increased accordingly to ensure the clarity of the picture.

In the darker environment, you can appropriately reduce the brightness of the display, so as not to be too bright and harsh. In addition, the matching of the background colour can also regulate the overall visual effect. For example, the use of dark coloured fonts on a white background can improve the clarity and contrast of the display.
