H040R-30MB-A1 is a circular 4-inch TFT LCD module. This LCD screen adopts an IPS panel, with a resolution of 720×720, full viewing Angle, MIPI 30-pin interface, JD9365DA Driver IC, and a brightness of 350nit. The working temperature can withstand -20℃ to +70℃, and a touch screen can be optionally equipped. This 4-inch circular TFT LCD screen is mainly applied in automotive and industrial instruments : suitable for automotive instrument panels, navigation systems or industrial control panels. Its circular shape matches the layout of traditional instruments, facilitating real-time monitoring of vehicle conditions or production processes. Professional instruments and interactive devices: including aviation instruments, audio mixing consoles or security monitoring terminals, utilize the ring-shaped display feature to optimize parameter visualization and operational efficiency. Smart home and control Terminal: In a smart home system, a 4-inch circular screen is often integrated into smart door locks (such as video door locks), central control panels or temperature control devices, used to display status information or operation interfaces. In addition, it can also be used in medical instruments. In fields such as industrial control instruments

This circular 4-inch display is ideally engineered for automotive instrument clusters, smart home control panels (such as thermostats and smart video door locks), medical devices, security monitoring setups, and diverse industrial control instruments.
Yes, while standard modules do not have touch integrated, a capacitive touch panel (CTP) is available as an optional feature. The interface definition reserved pins (Pins 25 to 30) for seamless touch integration.
The module utilizes a high-speed MIPI 30-pin interface along with the JD9365DA driver IC, supporting a full 16.7M color depth and 720×720 HD circular resolution.
The module is built for industrial-grade durability, operating reliably within a temperature range of -20℃ to +70℃, with storage tolerance spanning -25℃ to +75℃.
Featuring a luminance of 350 cd/m² and an IPS panel architecture, the module ensures clear visibility from all angles (full viewing direction) for both indoor and dashboard environments.
