Many customers often ask if it's feasible to switch from a projector to an LED display screen. The answer is definitely yes! LED displays are becoming increasingly widespread, installed in conference rooms, exhibition halls, banquet halls, media centers, command centers, and more. LED displays offer bright, vibrant colors, and screen sizes can be customized. They also maintain their color quality for several years without significant color decay.
Projectors, on the other hand, require curtains to be drawn in bright light and during the day, and their color decay becomes severe after a few years. Below, we'll use a 150-inch projector as an example, configured as a P1.86 full-color LED display:
We can find information online that the aspect ratio of a 150-inch projection screen varies, resulting in different lengths and widths. A 150-inch 16:9 screen is 332.08cm x 186.80cm; a 150-inch 4:3 screen is 304.8cm x 228.6cm.
A 150-inch projection screen has a total area of approximately 3.321m * 1.868m ≈ 6.20㎡. The P1.86 full-color screen module size is 320mm * 160mm. This 320mm * 160mm size is commonly used now because many video sources are 16:9 aspect ratio, so we'll use that for calculations. The length is approximately 3.321m / 0.32m ≈ 11 modules (rounded to the nearest integer), 11 modules * 0.32 = 3.52m. The height is approximately 1.868m / 0.16m ≈ 12 modules (rounded to the nearest integer), 12 modules * 0.16m = 1.92m. The P2 full-color screen area is approximately 3.52m * 1.92m ≈ 6.76㎡.
The size and area are similar to a 150-inch projection screen. A P1.86 full-color ultra-high-definition screen with a surface area of around 6 square meters would provide excellent results.
P1.8 small-pitch LED displays are used in multimedia conference rooms, a type of multi-functional conference room that has emerged and rapidly gained popularity in recent years, becoming standard equipment in hotels and businesses. Modern conference rooms can meet the needs of various reports, lectures, discussions, press conferences, training sessions, and academic exchanges (depending on specific requirements, they may also accommodate simultaneous interpretation, remote video conferencing, voting, cinematography, karaoke, etc.).
Modern multimedia conference systems include LED large-screen display systems, digital conference discussion systems, signal control systems, conference recording systems, multimedia audio and video switching systems, and conference sound reinforcement systems. A central integrated control system organically combines all these devices with the entire conference environment into a unified whole.
The core LED large-screen display is designed to process various graphic and textual information, including computer signals, DVD player signals, and video recorder signals. Commonly used equipment includes projectors or LED small-pitch displays. LED small-pitch displays offer advantages such as seamlessness, high brightness, high grayscale, high refresh rate, high contrast, wide viewing angle, and long lifespan, and have gradually replaced traditional screen displays, becoming the mainstream configuration for modern conference rooms.
In addition to the advantages of traditional LED screens, our system supports tablet control, eliminating the need to consider the computer's location or the speaker's position; a single iPad allows for mobile, remote control of the displayed content. The screen brightness can be adjusted with a single click based on the ambient light level, quickly, instantly, and effectively, without disrupting the meeting or requiring additional illuminance analysis.
When meetings are long, lowering the screen brightness effectively prevents eye strain and improves meeting efficiency. In bright sunlight or high-brightness indoor environments, increasing the brightness allows for clear video switching without curtains, and supports instantaneous switching between multiple video signals. It supports input from various devices such as laptops, USB drives, external hard drives, cameras, and DV camcorders; and supports playback of Office software such as PPT, Word, and Excel. For efficient heat dissipation, the system eliminates the need for a screen fan, achieving true "zero noise" and ensuring a pleasant meeting atmosphere.
When purchasing an LED display screen, please provide the following information carefully:
1. Installation Environment: Please specify the intended installation environment of the LED display screen: indoor or outdoor, wall-mounted, column-mounted, or other method.
2. Viewing Distance: Please provide the closest viewing distance after the LED display screen is installed.
3. Product Specifications and Model: Please specify the specifications of the LED display screen you wish to select. If unsure, please feel free to contact our sales staff by phone.
① Commonly used outdoor full-color LED display screen models include: P2.5, P3, P4, P5, P6, P8, P10
② Commonly used indoor full-color LED display screen models include: P1.25, P1.523, P1.667, P1.923, P2, P2.5, P3, P4, P5

4. Screen Size: Please specify the area of the LED display screen you wish to create, including its exact length and width, so we can provide you with a more detailed quote. If you only have an approximate area, we can recommend a standard aspect ratio of 4:3 or 16:9 for better image quality and display effect. When choosing the display screen model, both the screen size and viewing distance must be considered.
