IPS Display 2 Click

How does it work?

IPS Display 2 Click is based on the ER-TFT1.54-2, a 1.54" TFT LCD display without a touch panel from EastRising Technology. Designed for high-resolution visual output, this display offers a crisp 240x240 pixel resolution, ideal for applications requiring clear and vibrant graphics. It connects through an 15-pin FPC connector with a 0.3mm pitch, ensuring stable communication with the host system. This board is suitable for projects requiring a compact, high-resolution screen, such as handheld devices, smart displays, or informational panels.

Though the display is not sunlight-readable, its compact design integrates it into various indoor applications. With a diagonal size of 1.54 inches, it boasts a compact form factor, featuring an outline dimension of 31.52mm (W) by 313.72mm (H) with the FPC folded and a thickness of just 1.9mm. The visual area of 28.72mm by 28.72mm ensures an optimal display experience, while the active area of 27.72mm (W) by 27.72mm (H) provides high precision in rendering content. The dot pitch of 0.1155mm by 0.1155mm guarantees fine detail in the display's output.

The ER-TFT1.54-2 is driven by the ST7789V controller, a highly integrated single-chip controller and driver specifically designed for 262K-color graphic TFT-LCDs, offering vibrant color depth and smooth graphical performance. 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 RS 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.

Software Support

We provide a library for the IPS Display 2 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on MIKROE github account.

Library Description

This library contains API for IPS Display 2 Click driver.

Key functions

• ipsdisplay2_fill_screen This function fills the screen with the selected color.

• ipsdisplay2_write_string This function writes a text string starting from the selected position in a 6x12 font size with a specified color.

• ipsdisplay2_draw_line This function draws a line with a specified color.

Example Description

This example demonstrates the use of the IPS Display 2 Click by showing a practical example of using the implemented functions.
