Which Is Better for The EDP Interface Or LVDS Interface of Industrial LCD Screens?

Both the EDP interface and the LVDS interface are utilized by a wide variety of industrial LCD panels. These screens come in a wide variety of configurations. These video signal interfaces, which are also referred to as EDP and LVDS, are utilized in industrial computers for the purpose of connecting touch displays or LCD screens. Which of the two interfaces—the EDP interface or the LVDS interface—will be more advantageous to use? To be more specific, what is the difference? It will be investigated further down the road.

1.Introduction to EDP Interface

Additionally, there is a fully digital interface that is referred to as the EDP interface. This interface is founded on the DisplayPort architecture and protocol. The term "Embedded DisplayPort" is commonly used to refer to this interface when it is spoken in English. Some of the gadgets that typically make use of the communication interface include laptops, tablets, and computer screens. Other examples include other electronic devices. The display resolution of computers that make use of EDP display interfaces is superior to that of machines that make use of LVDS connections. The utilization of EDP communication interfaces, which are commonly utilized by high-definition screens, is typically the method by which wide-angle features are achieved. The screen interface is a 0.3-0.5 tiny pitch welded flat wire embedded within the EDP screen cable. This wire serves as the screen interface. Single channel and dual channel are the two categories that can be used to classify the EDP channel categorization. Twisted wires can be used to construct EDP screen cables in a variety of configurations, including 2, 3, 5, and 8 total wires. However, the most common configuration for EDP screen cables consists of two or three twisted wires for the signals.


2.Introduction to LVDS Interface

Low Voltage Differential Signaling (LVDS) is a sort of low voltage differential signal technology that is also known as that technology. LVDS is also referred to as that technology. When it comes to the delivery of broadband high bit rate data and the utilization of TTL level, it is a method of digital video signal transmission that was developed in order to address the issues of high power consumption and high electromagnetic interference (EMI). By utilizing low voltage amplitude and low current drive outputs, LVDS makes it possible to transfer signals at a rate of several hundred megabits per second (Mbps) over differential PCB pairs or balanced cables. This is made possible by the employment of LVDS. This is performed with the intention of achieving low noise levels and minimal power usage during the process. Two unique categories of LVDS screen cables are high-definition cables and standard-definition cables. Both of these categories can be distinguished from one another. In the same way as the high-definition line of the JAE FIRE51P takes the form of a double row with a spacing of 0.5, the high-definition line of the LVDS is likewise mirrored in this manner. Regarding the LVDS standard clearance line, the spacing is between 1.0 and 1.25, and rivets are used to assemble the terminals. Additionally, the spacing is between 1.0 and 1.25. In all-in-one computers that are used for industrial control, the LVDS interface is exploited to a significant degree.

Utilizing low-voltage and low-current driving methods is one of the most significant properties of the LVDS interface. This not only results in little noise but also in low power consumption, making it one of the most notable characteristics of the interface. The EDP interface takes advantage of a micro packet structure, which is one of the characteristics that sets it apart from other interfaces. Among the many advantages of this structure are its capacity to facilitate the simultaneous transmission of a large number of data, its straightforward circuit, and its ability to reduce electromagnetic interference. Because of this, the EDP interface has a transmission rate that is noticeably higher than the LVDS interface's rate of transmission. As an additional point of interest, high-definition screens often make use of the EDP communication interface in order to accomplish wide-angle capabilities.

In the case of an LCD panel with the same resolution, for example, the utilization of an LVDS interface requires the utilization of more than twenty pairs of data transmission pathways being utilized. In the event that an EDP interface is utilized, it is only necessary to have between four and six identical pairs of lines. Consequently, in comparison to other technologies, EDP offers a greater number of obvious advantages when it comes to high-resolution and high-definition panels. A substantial number of industrial LCD displays are currently making use of EDP interfaces in order to increase the speed at which data is transmitted between display panels and processors of the screen. This is being done in order to improve the efficiency of the data transmission process. Recently, electronic display panel (EDP) interfaces have become the most prominent technology in the areas of high-definition screens and full view screens. As a result of its low power consumption profile, low-voltage direct current (LVDS) is commonly utilized in the field of industrial LCD displays. This is in addition to the fact that it is able to fulfill the requirements of a diverse range of customers.
