HDMI


HDMI is an acronym for High-Definition Multimedia Interface.

HDMI means it is able to send a lot of data, very quickly. However, HDMI isn’t an analog communication like VGA, S-Video or parallel like 24-bit or 18-bit RGB TFTs. HDMI is actually a high-speed serial interface using a fancy TMDS (Transition Minimized Differential Signaling) protocol.

Unlike SPI where 1-bit is transferred per clock cycle, HDMI transfers 10-bits per clock cycle which further increases the bandwidth. The clock can be anywhere from 25 MHZ all the way to 340 MHz. This intense bandwidth allows HDMI standard to support up to an amazing 48 bits of color depth (that’s dense!).

For embedded applications, the typical color depth and resolution are well within HDMI’s capabilities. The important thing about Crystalfotnz HDMI embedded displays is that they give you an easy way to connect an embedded display to the now small and low cost embedded computers, such as a Raspberry Pi, or an Intel Compute Stick.
