“High-resolution visuals” maximize the value of information, while “audio design” creates a sense of unity within a space.
We consider large-scale audio-visual solutions not merely as equipment, but as “infrastructure that enhances communication”. In educational, business, and research environments, we propose visual and audio solutions that enable richer and more effective communication.
◇Large-Scale Visual Solutions
Display systems continue to grow in scale, and LED display technology now enables unprecedented flexibility in both size and form.
Leveraging our extensive experience in the design and delivery of projectors, LCD displays (including LCD video walls), and LED display, Totsu delivers optimized solutions tailored to each client’s needs. We also create immersive environments through the integration of large-scale and multi-screen displays with advanced audio solutions.
About LED Display
An LED display is a large-scale visual display system that uses light-emitting diodes (LEDs) as its light source, characterized by its high brightness and vivid image quality.
Because each LED functions as an individual pixel, images remain clear and detailed even when viewed from a distance. By combining multiple panels, large-scale displays of various sizes and shapes can be freely configured.
Unlike LCD video walls, LED displays enable the creation of seamless large-scale displays without bezels.

About LCD Video Walls
LCD video walls are created by arranging multiple displays to form a large visual surface.
They enable a wide range of visual expressions, such as displaying different content on each individual screen.
About High-Brightness, High-Resolution Projectors
By adopting laser light sources, these projectors achieve both high brightness and long lifespan. Compared to large-scale LED displays, they offer a more cost-effective solution for creating large-screen visual presentations.
◇Advantages and Disadvantages of Each Equipment
| LED Display | LCD Video Walls | Projectors | |
| Advantages | 1. High brightness and high contrast 2. Long lifespan and low power consumption 3. Flexible scalability in size and shape 4. Excellent color reproduction and video performance |
1. Lower initial installation cost 2. Shorter lead time |
1. Projection possible on any surface with sufficient wall space 2. Relatively low initial cost 3. Installation possible without construction work |
| Disadvantages | 1. Higher initial cost compared to other equipment 2. Longer lead time required |
1. Reduced visibility in bright environments 2. Fixed panel sizes limit flexibility in installation locations 3. Bezels become noticeable when configured as a large display |
1. Susceptible to ambient light conditions 2. Higher maintenance requirements, such as lamp replacement (lamp-based models) 3. Image quality may be affected by the installation environment 4. Limitations in achievable contrast ratio |
◇Audio Solutions
Audio systems consist of a wide range of equipment, including speakers, microphones, mixers, amplifiers, digital signal processors, and transmission cables. Each equipment has its own characteristics, making proper selection based on the installation environment and intended application essential.
Totsu has extensive expertise in designing and implementing large-scale audio-visual systems optimized for a wide range of applications.
Upon request, we also provide advanced acoustic measurements and simulations. By carefully selecting and precisely tuning equipment based on the size and geometry of the space, we deliver clear, balanced, and high-quality sound performance.
