Optoma 3653RK 65" 4K Creative Touch 3 Series Interactive Flat Panel Display price in Bangladesh

At its core, the panel features a 65-inch Ultra HD (3840 × 2160) resolution screen, offering sharp detail and vibrant color reproduction. The use of direct LED backlighting and a zero-bonding panel design minimizes the air gap between the glass and display, improving clarity while enhancing touch accuracy. The brightness level of about 450 nits and wide 178-degree viewing angles ensure that the display remains visible and consistent even in larger rooms with varied seating arrangements. With a dynamic contrast ratio of 5,000:1, the panel produces deep blacks and clear text, crucial for presentations and teaching materials.

One of the major strengths of this display is its interactive touch capability. The Optoma 3653RK supports up to 40 simultaneous touch points on Android and 50+ points when paired with Windows devices. This allows multiple users to write, draw, and interact at the same time, supporting group activities and collaborative sessions. The panel offers excellent touch accuracy (<1.0 mm) and a low latency of under 3.3 milliseconds, giving a natural and smooth writing experience whether using a stylus, finger, or palm. The glass surface is anti-glare and anti-fingerprint with a hardness rating of 7H, making it durable enough to withstand daily classroom or office use.

The built-in Android 14 operating system, powered by an octa-core processor with 8 GB of RAM and up to 128 GB storage (depending on region), provides a responsive interface for apps and collaboration software. Teachers and presenters can access Optoma’s whiteboard app, annotate over content, and share screens without needing an external PC. The Google EDLA certification ensures security, reliable updates, and seamless integration with Google’s ecosystem. For additional functionality, the OPS slot supports modular PC upgrades, while external laptops or desktops can be connected via HDMI, DisplayPort, or USB-C.

Connectivity is a major highlight of the 3653RK. It includes multiple HDMI ports, VGA, USB-A, USB-C, RJ-45, RS-232 control, and audio in/out, making it compatible with a wide range of devices. The panel also supports wireless screen sharing through Optoma’s “Display Share,” enabling users to mirror their smartphones, tablets, or laptops without extra hardware. The built-in 40-watt speakers provide clear sound for classrooms and small to medium-sized meeting rooms, eliminating the need for external speakers in many cases.

From a design perspective, the display has a slim bezel, durable construction, and a VESA mount pattern for flexible installation on walls or stands. It weighs about 40 kg and has an expected lifespan of 50,000 hours, ensuring long-term reliability. Power consumption averages around 140 watts, which is efficient for its size and capabilities.

In summary, the Optoma 3653RK is an all-in-one interactive solution that blends a sharp 4K display, robust touch functionality, versatile connectivity, and collaboration tools. It is particularly well-suited for educational institutions, corporate boardrooms, and training centers, where interactive learning and teamwork are essential. While it may not reach the brightness levels of premium digital signage, its balance of performance, features, and durability makes it a strong choice for most indoor professional environments.
