IPS Display 3 Click

How does it work?

IPS Display 3 Click is based on the ER-TFT0.99-2 display module from EastRising, which integrates a GC9107 controller in a chip-on-glass package. It provides a high-quality visual interface through its 0.99-inch IPS TFT LCD, designed for applications where space is limited but reliable display performance is required. This display features a 128x115 pixel resolution with a dot pitch of 0.190 by 0.190 millimeters, ensuring crisp and clear image reproduction. It employs IPS technology, delivering wide viewing angles of 80 degrees in all directions, a typical contrast ratio of 900:1, and brightness up to 450 cd/m2, making it suitable for diverse embedded systems where readability and color fidelity are important, though not optimized for direct sunlight visibility.

The display supports 4K, 65K, and 262K colors, offering flexible color depth options depending on application requirements. With a typical response time of 30 milliseconds, it provides smooth image transitions adequate for graphical user interfaces and simple animations. Display has an outline dimension of 26.71 by 26.22 millimeters and a slim 1.8 millimeter thickness including the folded FPC connector, while the active area of 24.36 by 21.89 millimeters ensures an efficient use of space for visible content. The visual area of 24.96 by 22.49 millimeters provides an optimal balance between display size and board footprint. IPS Display 3 Click does not feature a touch panel, maintaining simplicity for projects that rely on external input methods.

This board operates through a 3-wire serial SPI interface, ensuring smooth communication between the display and the host MCU. Beyond the SPI interface pins, the display also uses additional control signals for enhanced functionality. The RST pin plays a crucial role in ensuring reliable operation by allowing the display to be reset. This is essential for recovering from errors and initializing the display during power cycles. The BCK pin serves as a display backlight control, and the DC pin serves as a display data/command selection pin, crucial for distinguishing between data and command instructions sent via the SPI interface. This enables precise control over the display's functionality, ensuring that graphical content and operational commands are processed correctly.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Example Description

This example demonstrates the use of the IPS Display 3 Click board by showing a practical example of using the implemented functions.

Key Functions

• ipsdisplay3_cfg_setup This function initializes Click configuration structure to initial values.
• ipsdisplay3_init This function initializes all necessary pins and peripherals used for this Click board.
• ipsdisplay3_default_cfg This function executes a default configuration of IPS Display 3 Click board.
• ipsdisplay3_fill_screen This function fills the screen with the selected color.
• ipsdisplay3_write_string This function writes a text string starting from the selected position in configured font size with a specified color.
• ipsdisplay3_draw_line This function draws a line with a specified color.

Application Init

Initializes the driver and performs the Click default configuration.

Application Task

Showcases the text writing example as well as drawing pictures and objects, and filling the whole screen with a desired color. All data is logged on the USB UART where you can track the program flow.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
