FSTN (Film-compensated Super-twisted Nematic) provides a sharper contrast than STN by adding a film. The cost is approximately 5% higher than STN. FSTN works great for indoor and outdoor applications and is mainly used in graphic displays and higher end products. The Transflective polarizer is a mixture of Reflective and Transmissive. It provides the ability to read the LCD with or without the backlight on. It will work for all lighting conditions from dark with backlight to direct sunlight which makes it the most common choice. There is no cost difference between Transflective, Transmissive and Reflective.

means Twisted Nematic Liquid Crystal Display. It is the first commercial success LCD technology which is still widely used in low cost and low power consumption applications. Of course, we mean it passive TN LCDs.

If TN technology combined with TFT (Thin Film Transistor), it becomes active matrix display which is widely available for full color display market. Because the name of TN is very technical, when we hear TFT display which we know it is for short of TN type TFT LCD displays. How TN display technology works, showing in Fig.1.

STN LCD means Super Twist Nematic Liquid Crystal Display. TN LCD displays have the advantage of low cost and low power consumption, but it also has its intrinsic disadvantages, such as narrow viewing angle, poor contrast and limit to be used in high multiplex (duty) application.

They can only be used for some alphanumeric displays. Scientists and engineers invented STN LCD to overcome the limitation of TN LCD to make high duty graphic LCD display possible.

Compared with TN LCD’s 90otwist degree, STN LCD increases the twist to 180oto 270o. With this change, STN display’s electro-optical performance changes greatly. See Fig. 2.

Japanese scientists and engineers used a layer of retardation film to compensate the color to make STN color changing to Black and White. Monochrome black and white FSTN makes CSTN (Color STN) possible.

Compared with TN displays, FSTN displays have much higher contrast and wider viewing angles. But FSTN technology are only limited to passive matrix application. They can’t be used together with TFT technology like TN technology to become active matrix displays.

As FSTN LCDs can be made high density together with COG (Chip on Glass) technology, the FSTN display modules can be made high compact to make thin and light possible.

The same as other LCDs, FSTN LCDs can’t emit the light themselves. They have to assembled with backlight to make them LCD display modules to be able to use in applications. But backlight will drive a lot of power.

The parallel interface typically controls the LCD via 8 data pins and 3 control lines. The control lines used are Enable (E), Register Select (RS), and Read/Write (R/W). RS tells the LCD module if the information being sent is an Instruction or Data. The Enable tells the LCD module that the data or instruction in the register is ready to be interpreted by the LCD Module. Some controllers may have more than one Enable Control Line. The Read/Write tells the module whether to write data or read data from the register.

Serial LCD controllers typically have one Serial Data Line that writes data and cannot read. Normally, a Register Select Line(Sometimes designated A0) is used to tell the controller whether the incoming data is display information or a controller command

SPI, or Serial Peripheral Interface bus, is a synchronous (data is synchronized to the clock) serial data link standard that operates in full duplex mode, which means that devices that can communicate with one another simultaneously. To do this, two data lines are required. With this standard, devices communicate in a master/slave mode, where the master device (host processor) initiates the data and the clock. The LCD module is the (or one of the) peripheral slave device(s) attached to the data bus. Multiple peripherals (display modules and other devices) are addressed on the same serial data bus. However, the LCD module will only listen to the data it sees when the Chip Select line is active (usually low). If the Chip Select line is inactive (usually High), the LCD module listens to the data on the bus, but ignores it. The SDO line is not active when this state occurs. The SPI bus is comprised of four logic signals, two control lines and two data lines and is commonly referred to as SPI (4 wire).

With CS (Chip-Select) the corresponding peripheral device is selected by the LCD Controller. This pin is mostly active-low. In the unselected state the SDO lines are hi-impedance and therefore inactive. The clock line SCL is brought to the device whether it is selected or not. The clock serves as synchronization of the data communication.

The chip select signal CS is optional for a single device system, because you could tie the CS input at the LCD Module low, if the other lines are dedicated to SPI use. This is sometimes called a 3 Wire SPI Interface.

SPI Data transmissions usually involve two shift registers. Most display module applications normally use 8-bit words. However, different size words, such as 12 bit, are also used. By convention, the most significant bit is shifted out of one shift register while the least significant bit is shifted in. The word is then written into memory if the CS (chip-select) is low (active). If not, the data is ignored.
