The interface types used for LCD displays are diverse and versatile, including RGB, MCU, LVDS, and MIPI. Below is a brief overview of the structural principles of these interfaces:

RGB Interface:

Its transmits signals for the red, green, and blue color components, which are the fundamental elements for constructing color images.

Requires signals such as HSYNC (Horizontal Synchronization Signal), VSYNC (Vertical Synchronization Signal), ENABLE, CS (Chip Select Signal), RESET, and sometimes RS (Register Select Signal).

It is primarily used in small to medium-sized LCD display devices, such as 2.0", 2.31", 2.4", 2.8", 4.3", 5.0", 7.0", 9.0", and 10.1" screens.

MCU Interface:

It is mainly used in the field of microcontrollers. Widely adopted in smaller-sized mobile phones, featured of cost-effectiveness.

Standardized as the 8080 bus standard proposed by Intel, also referred to as DBI (Data Bus Interface), MPU (Microprocessor Interface), or CPU Interface.

It includes two modes: 8080 and 6800, differing in timing.

It supports data transmission of 8, 16, 18, and 24 bits.

Its typical signals such as WR (Write Signal), RD (Read Signal), RS, RESET, and CS.

Advantages: simple and convenient control, eliminating the need for clock and synchronization signals.

However, it consumes GRAM, limiting its use to smaller screens, typically 4" and below, such as 2.0", 2.31", 2.4", and 2.8" screens.

LVDS Interface:

LVDS (Low Voltage Differential Signaling) is a new generation of high-speed, long-distance transmission interface.

LVDS interface is also recognized as a low-voltage differential signaling technology interface developed to overcome the drawbacks of TTL-level transmission, such as high power consumption and EMI (Electromagnetic Interference) for broadband high-rate data transmission. Utilizes very low voltage swings (approximately 350mV) for differential data transmission over two PCB traces or a pair of balanced cables.

Compared to TTL interfaces, LVDS requires fewer cables, offers higher speeds, and consumes less power.

LVDS interface is widely used in high-resolution LCD displays and high-speed transmission applications.

MIPI Interface:

MIPI (Mobile Industry Processor Interface) is designed specifically for mobile devices.

MIPI Standards is a newly standard with ongoing modifications and improvements. Mostly its mature interface applications include DSI (Display Interface) and CSI (Camera Interface). CSI/DSI refer to their respective applications for cameras or displays, both having complex protocol structures.

MIPI interface an transmit multiple data and control signals per clock cycle, making it faster and more capable than TTL and LVDS interfaces.

It is widely used in modern smartphones, tablets, and other mobile devices.

Each of these interfaces has unique structural principles, suitable for different application scenarios and device types. When selecting an LCD screen interface for customization, the choice is primarily determined by the client's motherboard interface. Through software driver matching, the screen can be activated, realizing the product's display solution.
