SPI stands for Serial Peripheral Interface. SPI is a simple serial bus that is often used by LCD or OLED controllers. SPI as implemented for OLED and LCD controllers typically uses a “3-wire SPI” or “4-wire SPI” scheme. Detailed Definition SPI was originally championed by Motorola (now Freescale). In its original “pure” form SPI uses … Read more SPI
STN stands for Super-Twisted Nematic. STN is the commonly used LCD material in passive character and graphic LCDs.
TAB stands for tape automated bonding. Some of Crystalfontz’s displays use a TAB style tail that should be soldered directly to corresponding pads on a PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair … Read more TAB
TFT stands for Thin Film Transistor. TFTs are also known as “Active Matrix TFT LCD modules” and have an array of these thin film transistors fabricated on the glass that makes the LCD. There is one of these transistors for each pixel on the LCD. For a typical small color TFT LCD with a resolution … Read more TFT
TRANSFLECTIVE is a portmanteau of TRANSmissive and reFLECTIVE. A transflective LCD combines the best features of a reflective LCDs and transmissive LCDs. A transflective LCD will reflect ambient light, allowing it to be visible in normal office light without using a backlight. In bright sunlight, a transflective LCD is still visible and does not … Read more Transflective
A transmissive LCD depends on light from its backlight being transmitted through the LCD to your eyes. Transmissive LCDs are always combined with a backlight. Transmissive LCDs can be seen easily in normal office lighting, and in darkness. Typically transmissive LCDs will not be visible in bright sunlight. It is possible to make a sunlight … Read more Transmissive
ZIF: Short for Zero Insertion Force connector. This kind of connector is intended to be used with FPC (Flexible Printed Circuit) or FFC (Flat Flexible Cable). Typically a ZIF connector has a movable element that can be opened or closed. In the open position FPC/FFC can be easily slid in, then the connector is closed … Read more ZIF
