Principle of Work:

 

The Display Shield 3.2 inch TFT 480x320 HX8357C operates using a combination of the display module and the HX8357C driver IC. The display module is made up of multiple layers including the glass substrate, a color filter layer, and a thin-film transistor layer. When an electrical charge is applied to the thin-film transistor layer, it controls the passage of light through the color filter layer to create the displayed image. The HX8357C driver IC acts as a bridge between the microcontroller and the display module. It receives digital signals from the microcontroller and converts them into analog signals that are sent to the display module. The driver IC also contains advanced features such as hardware scrolling, windowing, and anti-aliasing that enhance the display's visual quality. To operate the display shield, a microcontroller such as an Arduino Mega or Due is connected to the shield's 16-bit parallel data bus. The microcontroller sends digital signals to the HX8357C driver IC, which converts them into analog signals that are sent to the display module. The module then displays the desired image or graphics on the screen. The SD card adapter on the back of the shield allows for easy storage and retrieval of images, videos, or other data without requiring additional hardware.

  tft.fillScreen(TFT_BLACK);    // Fill the screen with black color
  tft.setTextSize(2);           // Set the text size
  tft.setTextColor(TFT_WHITE);  // Set the text color to white
  tft.setCursor(80, 120);       // Set the cursor position to the center of the screen
  tft.print("Techmaze.ae");      // Print the text
}

void loop() {
  // Nothing to do here

Comparisons:

The HX8357 and ILI9481 Overall, are two different driver ICs and both are popular driver ICs that are suitable for a range of microcontroller-based projects. The choice between the two depends on the specific requirements of the project and the available budget, here are some of the differences between the two:

  • Color Reproduction: The HX8357 has better color reproduction than the ILI9481, with support for 16 million colors as opposed to the ILI9481's support for 65K colors. This means that the HX8357 can display more vibrant and accurate colors.
  • Refresh Rate: The HX8357 has a faster refresh rate compared to the ILI9481. This means that the HX8357 can display fast-moving graphics with less lag and motion blur.
  • Price: The HX8357 is generally more expensive than the ILI9481, which may be a consideration for some projects.
