Common and Custom Interfaces for TFT Displays

When selecting a display panel for our devices, in addition to evaluating the AA area (active area), peripheral dimensions, and the LCD panel's optical characteristics, it's crucial to choose a suitable interface mode for the LCD screen that matches our host controller board. The compatibility of the interface mode directly determines whether you can use a particular LCD display.

Rongen Display offers various commonly and customly TFT-LCD interfaces, and it's essential to pay special attention to whether the interface is compatible with your host controller board when making your selection. Based on our experience, we have compiled the following commonly used interfaces and provided brief explanations of their concepts and characteristics:

RGB (Red-Green-Blue) Interface:
RGB is a widely used analog interface that separates image data into its primary colors. It is known for its simplicity and versatility, making it suitable for various applications.


SPI (Serial Peripheral Interface) Interface:

SPI is a serial communication interface that is valued for its efficiency and straightforwardness. It is commonly employed in embedded systems and IoT devices.


MCU (Microcontroller Unit) Interface:

The MCU interface is tailored for microcontroller-based applications, simplifying connections for embedded systems.


MIPI (Mobile Industry Processor Interface) Interface:

MIPI interfaces are often found in mobile devices, providing high-speed data transfer and low EMI. They are ideal for compact and portable devices.


LVDS (Low-Voltage Differential Signaling) Interface:

LVDS provides high-speed data transmission with low power consumption and is used in applications where noise immunity and high bandwidth are critical, such as industrial and automotive systems.


eDP (Embedded DisplayPort) Interface:

eDP is commonly used in laptops and tablets, offering high-quality video and audio signals with minimal power consumption.


I2C (Inter-Integrated Circuit) Interface:

I2C is a two-wire communication interface suitable for applications where multiple devices need to communicate with each other.


VGA (Video Graphics Array) Interface:

VGA is an analog video interface primarily used for older computer displays. It is gradually being phased out in favor of digital interfaces.


HDMI (High-Definition Multimedia Interface) Interface:

HDMI is a popular digital interface for high-definition audio and video transmission, commonly used in modern home entertainment systems.


USB (Universal Serial Bus) Interface:

USB interfaces serve various purposes, including data transfer, power supply, and connecting peripheral devices.


These interfaces offer a range of features and characteristics, and the choice depends on your specific application requirements, including data transfer speed, power consumption, and compatibility with your host controller board.
