TM035KDH03 Display Performance and Optical Characteristics
The TM035KDH03 is designed to balance low power consumption and clear image quality, making it suitable for indoor and light outdoor HMI applications. Its key display and optical parameters are outlined below.
Drive Interface and Hardware Compatibility
The module uses a standard 50-pin Digital RGB interface (24-bit/18-bit) and can connect to popular MCUs and embedded processors such as STM32, ESP32, and NXP i.MX series. The built-in display driver includes basic timing control and bias voltage generation, simplifying driver development.
Power Management and Thermal Control
Designed for handheld devices, the TM035KDH03 is optimized for low power consumption. Its backlight typically uses six LEDs in series or parallel, with an operating current of around 20 mA and total power consumption below 0.5 W, making it suitable for battery-powered terminals.
Environmental Performance and Mechanical Design
The module features a compact design and operates from -20°C to +70°C, with a storage temperature range of -30℃ to +80℃. It offers good resistance to vibration and interference and can be used in outdoor environments with appropriate structural protection.
TM035KDH03 Backlight and Power Requirements
The TM035KDH03 backlight typically uses six high-brightness white LEDs (WLEDs), usually connected in series. Under standard conditions, the backlight current is 20 mA, with a typical forward voltage of 18–20 V.
For logic and LCD power, the module uses a standard 3.3 V (VCC/VDD) supply, with only a few milliamps of operating current. In some designs, if the driver IC does not include a boost circuit, external circuitry may be required to provide bias voltages such as VGH (about 15 V) and VGL (about -10 V).
The total module power consumption, including the backlight, is typically around 0.4–0.5 W. For PCB layout, keep the backlight boost circuit away from sensitive RGB signal lines and use proper power filtering to reduce switching noise and display interference.
TM035KDH03 Block Diagram
The TM035KDH03 display module consists mainly of a 3.5-inch LCD panel (320 × 240), COG LCD driver IC, backlight unit (B/L), and FPC interface. The main board sends 24-bit RGB/CCIR image data (D00–D23), timing signals (HSYNC, VSYNC, CLK), SPI configuration signals, power, and backlight control through the FPC. The integrated Source/Gate Driver, TCON, grayscale voltage, charge pump, and VCOM circuits work together to control the LCD pixels and display images.
