1.8 Inch Serial SPI TFT LCD Display Module Price in Bangladesh

The 1.8 Inch Serial SPI TFT LCD Display Module is a compact color screen designed for displaying text, numbers, graphics, sensor readings and graphical user interfaces in electronic projects. Its small footprint makes it useful for applications where a larger display would occupy too much space.

Unlike a basic monochrome LCD, this TFT display can present colorful information, icons, menus and simple graphical elements. This makes it suitable for Arduino projects, ESP32 development, embedded electronics, portable instruments and student experiments.

The module typically provides a resolution of 128 × 160 pixels and uses an SPI communication interface. SPI allows a microcontroller to transfer display data using a small number of communication lines, helping preserve GPIO pins for sensors, buttons and other peripherals. Many versions use the ST7735 or ST7735S display controller, which is supported by commonly used graphics libraries.

Whether you are developing a digital measuring instrument, a sensor dashboard or a small handheld device, this display provides an accessible way to add color and graphical feedback to your design.

What Is a Serial SPI TFT LCD?

A TFT LCD is a thin-film-transistor liquid crystal display that uses individual pixel control to produce images and text. The SPI interface is a serial communication method that transfers commands and display data between a controller and the display module.

Using SPI reduces the number of data connections compared with a typical parallel display interface. The microcontroller sends commands to configure the display and then transfers pixel data to draw text, lines, shapes, images and other graphical elements.

Key Features

• Compact 1.8-inch screen: Suitable for small electronic devices and portable projects.
• Color graphics: Supports colorful text, icons and interface elements.
• 128 × 160 resolution: Provides 20,480 individual pixels for displaying information.
• SPI communication: Helps reduce the number of GPIO pins needed.
• Microcontroller compatibility: Suitable for compatible Arduino, ESP32, STM32 and Raspberry Pi projects.
• Graphics library support: Common controller variants work with libraries such as Adafruit GFX and Adafruit ST7735.
• Sensor data visualization: Can display numerical readings and basic graphs.
• Menu interfaces: Useful for project settings, status screens and navigation menus.
• Compact PCB construction: Convenient for breadboard prototypes and custom electronics enclosures.
• Educational value: Helps students learn display programming, SPI communication and graphical interface development.

Technical Specifications

Important: Some modules accept 3.3V only, while others include voltage regulation or level shifting for 5V systems. Confirm the board’s pin labels and specifications before connecting it to a controller.

Working Principle

The TFT panel displays images by controlling the light transmission of its pixels. The display controller manages the commands and pixel data sent from the connected microcontroller.

When the project program sends a display command, the controller configures the screen or selects a drawing operation. The microcontroller can then send pixel data to display text, graphics, colors and numerical values.

The SPI interface transfers this information serially over clock and data lines, with additional control pins typically used for chip selection, reset and data/command selection.

With a suitable graphics library, a developer can draw shapes, print text, create simple animations and show readings from sensors connected to the same microcontroller.

Applications

1. Arduino Projects

Use the display with Arduino UNO, Mega or compatible boards to create small information screens and interactive electronic prototypes.

2. ESP32 and IoT Devices

Display sensor readings, connection status, temperature, humidity and other project information locally.

3. Digital Measuring Instruments

Develop compact interfaces for voltmeters, thermometers, counters and other low-voltage measuring projects.

4. Robotics Projects

Show robot status, sensor values, operating modes and other diagnostic information.

5. Portable Electronics

Integrate a small color interface into handheld devices and battery-powered prototypes.

6. Data Monitoring

Display numerical measurements, simple charts and status indicators from connected sensors.

7. Educational Laboratories

Demonstrate SPI communication, display initialization, pixel graphics and microcontroller programming.

8. Custom User Interfaces

Build simple menus, icons, progress indicators and graphical status screens for DIY electronics.

Advantages

Small form factor: The compact screen is appropriate for projects with limited mounting space.

Color display: Color coding can make readings, warnings and status information easier to interpret.

Efficient communication: SPI reduces the number of signal connections required compared with many parallel displays.

Flexible programming: Common graphics libraries make it easier to create custom interfaces.

Broad application potential: The display can be adapted to numerous embedded systems and electronics experiments.

Limitations

• The 128 × 160 resolution is suitable for basic graphics but limited for detailed images or complex interfaces.
• A 1.8-inch screen may be difficult to read from a distance.
• SPI communication uses GPIO pins and may require careful pin selection when other SPI devices are connected.
• Controller initialization settings can differ between module revisions.
• Some versions do not include a microSD card slot or touch functionality.
• A module without suitable level shifting may be damaged by incompatible logic voltages.

Installation and Usage Tips

1. Identify the display controller and pin labels on your specific module.
2. Confirm the supported supply voltage and logic levels before connecting power.
3. Connect the SPI clock and data pins to compatible microcontroller pins.
4. Connect the CS, DC and reset pins as required by the library and module.
5. Install a graphics library compatible with the controller.
6. Select the correct display initialization option and orientation.
7. Begin with a basic test sketch that displays text and colored shapes.
8. Check wiring and pin assignments if the screen remains blank or displays incorrect colors.
9. Avoid applying excessive pressure to the LCD panel.
10. Provide suitable backlight power and avoid exceeding the module’s electrical ratings.
