The difference between EDP and LVDS interface

EDP and LVDS are two common interface technologies. This article will provide you with a detailed analysis of the technical characteristics, application scenarios and differences between EDP and LVDS interfaces.

EDP interface
1.Technical features: EDP is a high-performance, low-cost display interface technology formulated by VESA. The EDP interface supports higher data transmission rates, reaching 1.62Gbps, 2.7Gbps and 5.4Gbps, and is suitable for high-resolution, high-refresh rate display devices.
2.Application scenario: The EDP interface has high transmission rate and low power consumption, and is particularly suitable for high-performance display devices.

LVDS interface
1.Technical features: LVDS is a low-voltage differential signal transmission technology with the characteristics of high speed and low power consumption. The LVDS interface supports lower data transmission rates, such as 162Mbps, 324Mbps, etc., and is suitable for lower resolution display devices.
2.Application scenarios:LVDS interface is widely used in display devices in industrial control, medical equipment, vehicle navigation and other fields. Its lower transmission rate and mature technology are particularly suitable for scenarios that do not require very high display performance.

The difference between EDP and LVDS interfaces
1.Transmission rate:The EDP interface has a high transmission rate, up to 5.4Gbps, while the LVDS interface has a relatively low transmission rate, up to 324Mbps. Therefore, the EDP interface is more suitable for high-resolution, high-refresh-rate display devices.
2.Power consumption:The EDP interface has low power consumption and is particularly suitable for battery-powered devices such as laptops. Although the LVDS interface also has low power consumption, its power consumption is relatively high on high-performance display devices.
3.Cost: Due to its mature technology, the cost of the LVDS interface is relatively low. As the EDP interface is relatively new in technology, its cost is relatively high.
4.Application scenarios:The EDP interface is particularly suitable for high-performance display devices, such as 4K resolution monitors. The LVDS interface is more suitable for scenarios that do not require very high display performance, such as industrial control, medical equipment, etc.

Summary: EDP and LVDS interfaces have their own characteristics and are suitable for different application scenarios. Understanding their technical characteristics, application scenarios and differences will help us make the right choice when choosing an LCD display. With the continuous advancement of technology, more high-performance, low-cost interface technologies may appear in the future, bringing more possibilities to LCD display applications.
