Seiko Epson Corporation (“Epson”) has begun shipping samples of the S1D13709, a new display controller IC with built-in memory that is capable of easily controlling the display of both text and graphics on color TFT[1] and STN[2] LCD panels. This display controller is ideal for control panels used on factory automation equipment and office equipment such as printers and multifunction units.

STN panels are often used as control panels on factory automation systems and office equipment, but demand for color TFT panels in these applications has been growing in recent years because of their good visibility and greater powers of expression. The new S1D13709, with built-in CGROM[3], can enable such popular features as mixed text and graphics, overlays, and smooth scrolling (vertical and horizontal) on both STN and TFT LCD panels. In addition, since memory for the display is built-in, no external memory is needed. This saves space and design work for users. The software of the new S1D13709 is compatible with that of the S1D13700, Epson’s previous display controller IC for monochrome STN LCD panels. This makes it easy for S1D13700 users to migrate to color TFT LCD panels.

Going forward, Epson intends to leverage its unique set of compact, energy-saving, and high-precision technologies to help enrich society by providing products and services that solve real issues for customers.

Users of the S1D13700, Epson’s previous display controller IC for monochrome STN display panels, can use the new S1D13709 with their existing software to control color TFT LCDs (some restrictions apply).

Hantronix TFT LCDs will deliver a vibrant, high contrast user interface to any application. Our TFT displays are available in a wide range of sizes, and are easy to incorporate into any design. We offer the most popular and cost-effective Amorphous Silicon Thin Film Transistor or a-SiTFT panels. This application note discusses how to drive a TFT LCD using widely available microprocessors.

Note that some small, lower end panels may not have all of the electronics included with them because of size or cost restraints. Some panels have a simple row and column interface. Some may need an external timing controller. Some have a processor bus type Interface.

Many LCD controllers, including those integrated into microcontrollers, will directly drive the signals shown in Figure 1. This means that the biggest obstacle to quickly getting an image on the screen is generating the appropriate signal timing. The LCD controller is responsible for generating the timing; however software must be written to correctly program the controller for the specific LCD model.

An LCD panel comprises a matrix of pixels (picture elements), divided into red, green, and blue "sub-pix-els". Each sub-pixel is driven by a small transistor. Typically, LCD panels have internal row and column drivers, much like DRAM. A row is selected by the row driver, then the column driver sequences through each of the columns. After each of the columns has been written, the row driver selects the next row and the process repeats. The VSYNC signal resets both row and column drivers to the upper left pixel. The HSYNC causes the row driver to step to the new row. The clock sequences the column driver through each of the pixels, with each clock edge latching data values for the red, green, and blue sub-pixels. These values drive a form of D/A converter to store an electrical charge in a capacitor in each sub-pixel which controls the drive of the transistor; this in turn controls the brightness of the sub-pixel. A red-green-blue color mask is used to filter the light from each sub-pixel to form its corresponding color.

Like a DRAM, an LCD panel must be constantly refreshed or the image will fade. Most TFT LCD panels work when refreshed around 60 Hz. The imagedata is usually held in a section of main memory called a frame Buffer.

Each location in the frame buffer corresponds to a pixel on the LCD. The value in the location determines the color displayed for that pixel. See Figure 2. The size of the frame buffer depends on two things: the number of locations needed, and the size of each location.

TFT panels typically have an input of at least 6 bits of red data, 6 bits of green data, and 6 bits of blue data. A panel with 6 red, 6 green, and 6 blue data lines is termed a 6-bit panel. If the processor or LCD controller doesn"t drive as many data lines as the panel requires, use the data line configuration shown in Figure 3 or Figure 5.

Seiko Epson Corporation announced that it will in September start supplying its latest display controller IC reference design compatible with the Arduino Due including the Atmel SAM3X8E 32-bit microcontroller based on ARM"s Cortex-M3 open source hardware platform. This new reference design will support the development of products using small- and medium-sized TFT LCD panels, providing significantly shorter development times and a lower cost evaluation environment. The reference design includes an evaluation board with an integrated S1D13781 LCD controller IC manufactured by Epson and a software library providing simple graphics functions.

The S1D13781 Shield TFT evaluation board is compatible with Arduino Due. Both this evaluation board and the software library were developed to be compatible with the Arduino Due environment, providing a simple hardware connection that allows the evaluation board to be powered by Arduino Due, and with simple software installation and usage. The evaluation board includes two FPC (Flexible printed circuits: It"s possible to easily change the shape of these flexible circuits without affecting their electrical characteristics) connectors (40-pin and 54-pin) that can be used to connect to separately available WQVGA (400x240 dot) or QVGA (320x240 dot) TFT panels.

The S1D13781 Shield TFT evaluation board can also be used to evaluate the low cost S1D13L01 LCD controller that shares the same features as the S1D13781, except for BitBLT functionality (A function that transfers bitmap images used on the display from the main memory to the graphics memory). The evaluation board will be available for purchase from online shops in September. To be made available on Epson"s website from September 2015.

If the controller is on the back of the LCD, then you are in luck. If it"s not, then you will have to find an equivalent LCD controller and design a PCB with a microcontroller on it.

The first thing to do is find the datasheet for the LCD controller chip, without this you have a real uphill battle. If you know the manufacturer and find the package this might help you reverse engineer your module. Some companies only provide datasheets on request, some you have to have an agreement with them.

If what you have salvaged is an LCD module that is manufactured, this will be easier to interface to as the manufacturer will in all likely hood have the datasheet and drivers.

Once you have found the datasheet, you can then figure out how to interface to it. The LCD controller will either be a parallel (for the bigger screens with a faster update) or a serial (smaller screens with a slower update). Some of the serial screens use SPI. The parallel ones will have data and address lines and control lines similar to writing to memory.

Then connect your microprocessor to the data (and or address lines) and see if you can access a register and read and write data to the LCD (preferably control registers to test communication).

Remember that to implement one interface to an LCD can take man months of time to implement for a product, a project like this can really help you appreciate economies of scale.
