Selecting a COB LED display requires more than comparing pixel pitch and purchase price. A display installed in a control room has different requirements from one used in a boardroom, retail showroom, broadcast studio, museum, or exhibition hall. Viewing distance, screen size, content detail, installation structure, maintenance access, operating hours, and room lighting all affect the final product choice. Buyers should match the product series to the actual environment instead of automatically choosing the smallest pixel pitch.
A cob led screen mounts multiple LED chips directly onto the circuit board and protects them with an integrated surface layer. This structure supports fine pixel pitches, smooth display surfaces, close-range viewing, and better protection against impact, dust, and moisture. JR Visual currently provides several COB product series for different indoor projects, including M-COB, iX-III, iTmax, and the iX Series. Available pixel pitches cover 0.6mm to 1.8mm, while the standard 600 × 337.5mm cabinet follows a 16:9 aspect ratio.
Choose Pixel Pitch Based on Viewing Distance
Pixel pitch refers to the distance between the centres of adjacent LED pixels. A smaller pixel pitch places more pixels within the same display area, helping viewers read small text and see detailed images from a shorter distance. P0.6, P0.7, and P0.9 COB displays are more suitable for command centres, broadcast studios, executive meeting rooms, and other spaces where viewers sit close to the screen. These applications often display maps, spreadsheets, surveillance feeds, charts, and detailed presentation content.
P1.2 and P1.5 can provide a more balanced option for corporate meeting rooms, training centres, showrooms, and exhibition halls. They maintain suitable image detail while controlling the total project cost. P1.8 may suit larger indoor spaces where the viewing distance is longer, and the content mainly includes videos, large images, or simple presentation graphics.
Because the suitable viewing distance changes with pixel pitch, buyers should evaluate the actual room layout before selecting a display. Choosing a finer pitch than the application requires can increase the project cost without creating a noticeable improvement for viewers. A High-pixel-pitch LED display may work in projects with longer viewing distances and less detailed content. However, it is not a suitable replacement for a fine-pitch COB display when users need to read small text or examine detailed visual data from close range.
M-COB for Control Rooms and Monitoring Centres
Control rooms regularly display maps, alarm information, equipment status, surveillance video, and operating data. Displays may run for long hours, so the installation should provide stable performance and convenient front access. The M-COB LED Display is a reasonable option for traffic control centres, security monitoring rooms, factory control rooms, data centres, and emergency command centres.
M-COB offers pixel pitches from P0.6 to P1.8. Buyers can select P0.6 or P0.9 for close-viewing environments with detailed data, while P1.2, P1.5, or P1.8 may suit larger monitoring rooms with longer viewing distances. Its lightweight cabinet integrates the power supply, receiving card, and hub card into one structure. This reduces internal wiring and allows the cabinet to be mounted directly onto the wall. This design is useful when a control room has limited space behind the display. The protected COB surface also reduces the risk of damage when technicians clean or maintain the screen.
iX-III for Meeting Rooms and Boardrooms
Meeting rooms place users relatively close to the display. Documents, spreadsheets, diagrams, video calls, and presentation slides must remain clear from different seats around the room. The iX-III COB Indoor LED Display is suitable for boardrooms, conference rooms, training rooms, executive briefing rooms, and multipurpose corporate spaces. The series supports P0.6, P0.7, P0.9, P1.2, and P1.5 configurations. P0.9 may suit executive boardrooms where users sit close to the display and regularly view detailed documents. P1.2 or P1.5 can provide a more economical configuration for larger conference rooms.
Its 600 × 337.5mm cabinet follows a 16:9 ratio, helping system designers build standard display formats for presentations and video conferencing. The cabinet is 38mm thick, allowing it to fit into corporate interiors without creating excessive wall depth. The iX-III also supports concave and right-angle configurations. These options are useful when the display needs to follow a curved wall or continue around an interior corner. Its protective surface and colour-calibration features also support long-term use in professional indoor environments.
iTmax for Studios and High-End Showrooms
Broadcast studios, luxury retail stores, brand experience centres, and premium exhibition spaces place greater emphasis on contrast, viewing angle, surface appearance, and installation flexibility. The iTmax COB LED Display is more suitable for these high-end visual applications. It offers P0.7, P0.9, P1.2, and P1.5 options. Its high-contrast black surface helps dark backgrounds, branded videos, digital artwork, and premium product images appear deeper and more detailed.
The wide viewing angle is useful in retail stores and exhibition halls because visitors do not always stand directly in front of the display. Customers moving through the space can still see clear images from different positions. iTmax supports wall-mounted and hanging installations. Its corner-cut cabinet structure can also support cube-style and creative display formats. These options make it suitable for flagship stores, airport commercial areas, studio backgrounds, exhibition booths, and immersive brand environments. For a standard flat retail video wall, M-COB may provide a more cost-controlled solution. For a flagship store that requires deeper blacks, wider side viewing, or a creative screen structure, iTmax provides a stronger match.
iX Series for Slim Fixed Installations
Government halls, museums, corporate reception areas, public buildings, and premium commercial spaces often need a thin fixed display that fits closely against the wall. The iX Series Indoor COB LED Display uses a 600 × 337.5mm cabinet with a thickness of 27.5mm. This slim structure helps reduce the total installation depth and allows the screen to blend into modern interior designs. The series provides front-mounted wall brackets and a fast-lock system for accurate installation. These features are useful when there is no maintenance corridor behind the display.
A slim LED display panel can be installed in reception areas, museums, government facilities, corporate lobbies, and exhibition spaces where the display cannot extend too far from the wall. The iX Series supports both COB and SMD technologies, giving system integrators more flexibility when different areas of a project have different image-quality requirements or budgets. It has also passed the EN13501 fire test, which may support projects that require fire-performance documentation during approval or tendering. Its support for flat, curved, and cube-style structures also makes it suitable for installations that need more than a conventional rectangular video wall.
Select Products for Retail and Exhibition Spaces
Retail projects can range from standard advertising walls to immersive flagship-store installations. Buyers should select the product according to viewing distance, lighting, content type, and the required screen shape. M-COB can support standard indoor retail video walls where the project needs a protected surface, direct wall mounting, and fine-pitch image quality. iTmax is more suitable for luxury stores and brand showrooms that display dark product images, premium promotional video, or creative screen structures. Its high contrast and wide viewing angle allow customers to see consistent content while walking through the space.
The iX Series suits stores, museums, and exhibitions that need a slim wall-mounted screen or a display integrated into a customised interior structure. P0.9 or P1.2 may suit screens installed behind counters or close to product display areas. P1.5 or P1.8 can be more economical for larger advertising walls viewed from farther away. Strong interior lighting can also affect perceived contrast. Buyers should test the COB surface under the actual shop, museum, or exhibition lighting before approving the final product.
Compare the Complete Project Cost
The display quotation represents only one part of the total project cost. Buyers should also calculate the supporting structure, installation labour, control system, video processor, power distribution, transportation, spare parts, and future maintenance. Smaller pixel pitches contain more pixels and normally cost more. Choosing P0.6 for a room that only requires P1.5 can increase the display cost and processing requirements without producing a visible improvement for the audience. COB displays may have a higher initial price than some SMD products. However, their protected surfaces can reduce damage during transportation, installation, cleaning, and daily operation.
Maintenance access also affects long-term costs. A screen installed directly against a wall should support front maintenance. Otherwise, technicians may need to dismantle surrounding decoration or remove complete cabinets to replace a small component. Buyers should compare expected operating hours, viewing requirements, installation conditions, maintenance access, and replacement risks instead of judging the project only by the display price per square metre.
Which COB LED Display Should You Buy?
M-COB is suitable for control rooms, monitoring centres, corporate offices, training rooms, and standard retail video walls that need direct wall mounting and an integrated cabinet structure. iX-III is suitable for boardrooms, conference rooms, executive briefing rooms, and corporate spaces where viewers sit close to the display and regularly view documents or detailed presentation content. iTmax fits broadcast studios, luxury showrooms, exhibition spaces, flagship stores, and creative commercial installations that require high contrast, wide viewing angles, or flexible installation methods.
The iX Series works well for museums, government buildings, corporate reception areas, and slim fixed installations that require front installation, a thin cabinet, fire-test documentation, or curved and cube-style screen structures. Before requesting a quotation, buyers should provide the screen width and height, minimum viewing distance, target resolution, content format, installation method, wall condition, daily operating hours, maintenance space, and required certifications. Matching the product series and pixel pitch to the actual environment helps buyers control costs while achieving the required image quality, installation result, and long-term reliability.
