The embedded display buffer allows WQVGA up to 480x272 at 24bpp or 800x480 8bpp for single layer display, or 480x272 at 16bpp (Main layer) and 480x272 at 8bpp (PIP layer) for two layer display.

Epson Display Controllers reduce the load on the main CPU by off-loading the display process to a discrete display controller. The controllers combine high-speed display output with additional features that add capability to both new and revised designs, while maintaining industry leading low power consumption. Epson Display Controllers offer excellent solutions for embedded equipment, mobile terminals, automotive equipment, and a wide variety of other applications.

Easy TFT display control, combining XMC™ microcontroller with EPSON S1D13781 TFT CTRL IC. The S1D13781 embedded graphic accelerator and video memory is controlled by EPSON’s free-of-charge Graphics Library/API running on XMC™ MCU. System resource free-up, scalability up to 7“ displays and 800x480 resolution, and exciting HMI experience are only some of the benefits.

Epson LCD drivers, developed from the display ICs for digital watches, have been driving display panels of mobile phones around the world. Our many years of technological expertise have yielded a number of LCD driver options for diverse LCD panels.

Simple LCDC series is applicable to TFT LCD panel from QVGA up to WVGA resolution and suitable for FA controller, medical instrument, measurement equipment and OA applications.

Seiko Epson Corporation started supplying its latest display controller IC reference design compatible with the Arduino Due 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 connectors (40-pin and 54-pin) that can be used to connect to separately available WQVGA (480×272 dot) or QVGA (320×240 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. The evaluation board is available for purchase from online shops from September. Sample software can be downloaded free-of-charge from Epson with user registration.

“Going forward, Epson will continue to release display controller IC reference designs,” said Kazuhiro Takenaka, deputy chief operating officer of Epson’s Microdevices Operations Division. “Our aim is to help our customers by supporting higher resolution small- and medium-sized TFT LCD panels and evaluation boards with other microcontrollers.”

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.

2017/03 To Small-medium TFT-LCD requirement, RAIO announce its new RA8871M/RA8873M controller, with the powerful features make the device suitable for both HVGA and WVGA display applications in the mainstream market.

Seiko Epson Corporation (TSE: 6724, “Epson”) has begun volume production of S1D13L04 display controllers that support color TFT*1 liquid crystal display panels with up to XGA resolution. Epson plans to produce 20,000 units per month.

Manufacturers are increasingly demanding color TFT liquid crystal display panels for use in industrial equipment and medical instrument control panels because of their good visibility and rendering capability. Moreover, as prices for color TFT LCDs fall, they are adopting larger panel sizes and higher resolutions (e.g., XGA). In addition, low-power devices are increasingly required for mobile devices and environmentally-conscious manufacturing.

In response to these needs, Epson developed the S1D13L04. The latest addition to Epson’s simple LCD controller series, the S1D13L04 is a low-cost, low-power solution that provides the essential functions of a display controller.

*1 A type of active-matrix liquid crystal display that uses thin-film transistors (TFTs). They are widely used for displays on products such as PCs and LCD TVs.
