Texas Instruments Incorporated today introduced six- and four-channel electromagnetic interference (EMI) filters for LCD display applications, the TPD6F202 and TPD4F202. Electrostatic discharge (ESD) ratings exceed the IEC 61000-4-2 specification by at least three times for contact discharge. Both are 67 percent better than the specification for air-gap discharge. This allows the signal to be transmitted through the device while it filters out the higher frequency RF and electromagnetic interferences (RF/EMI) that can appear as lines on a screen, especially LCD displays. The devices" compact size allows designers to optimize previously wasted space under connectors. Targeted applications include LCD display interfaces and anything that needs RF/EMI filtering on data lines, such as portable applications, cell phones, LCD interfaces, and video connections.

Flat Panel Display Link, more commonly referred to as FPD-Link, is the original high-speed digital video interface created in 1996 by National Semiconductor (now within Texas Instruments). It is a free and open standard for connecting the output from a graphics processing unit in a laptop, tablet computer, flat panel display, or LCD television to the display panel"s timing controller. Most laptops, tablet computers, flat-panel monitors, and TVs use the interface internally.

Another display interface based on FPD-Link is OpenLDI. It enables longer cable lengths because of a built-in DC balance coding to reduce the effects of intersymbol interference. In the OpenLDI version of DC balance coding, one of the seven serialized bits indicates whether the coding scheme needs to invert the other six bits transmitted in the clock period to maintain DC balance. Therefore, each LVDS pair other than the clock pair effectively transmits six bits per clock cycle. However, OpenLDI lost the video-transfer standards competition to Digital Visual Interface (DVI) in the early twenty-first century, and the result was stand-alone LCD panels using DVI to receive video from a desktop computer.

FPD-Link III"s embedded control channel uses the I2C bus protocol between the source and destination in the first implementations (however, it is not limited to I2C). The I2C master can read and write to all the slaves on the other side of the FPD-Link III chipset, which is effectively transparent to the I2C master and slaves communications. For example, this enables infotainment head units to control and configure displays, and image processing units to control and configure cameras using the same twisted pair cable as the data transmission.
