reference design for tft lcd panel price

Have your product stand out with the DT050ATFT display - our 5” TFT LCD module with full viewing angle. The full viewing angle feature allows the display contents of the LCD to be visible from practically any angle. It"s a cost-effective enhancement compared to using an IPS display. The 5" TFT has 800 x 480 RGB resolution and supports 24-bit parallel RGB input mode. The LCD uses two driver ICs to drive the display: a source driver with TCON (Ilitek ILI6122) and a gate driver (Ilitek ILI5960). It also is available with either a resistive touchscreen or capacitive touchscreen panel. This 5 inch LCD is an ideal option for a variety of digital devices including video or POS systems.

Improve your product design by adding the DT010ATFT: a small, simple 1” TFT LCD with IPS technology. This mini TFT display is perfect as a status indicator presenting graphic icons or simplified information. The IPS technology included in this display allows your content to be crisp and clear no matter what angle your user is viewing it from. The ST7735S driver IC provides on-chip storage and power system. This IC allows for fewer components and a simple design to easily integrate the DT010ATFT into your next product.

The TFT LCD Controller Reference Design from Digital Blocks enables hardware designers to accelerate the design-in of TFT LCD panel displays into their system. The Reference Design centers on Digital Blocks DB9000AVLN TFT LCD Controller IP Core, which is available in Altera® netlist or Verilog RTL formats.

The DB9000AVLN contains an Altera Avalon® System Interconnect for interface to the NIOS® II processor and SDRAM or SRAM controllers. Either memory can serve as the Frame Buffer. Software supplied with the Reference Design runs on the NIOS®II processor to place an image in Frame Buffer memory and setup & invoke the DB9000AVLN to drive the LCD panel.

Utilizing Altera’s Quartus II tools, the Reference Design places into an Altera Cyclone, Stratix, or Arria series FPGA development kit. All Altera FPGAs are supported.

In addition to supporting the Altera Avalon System Interconnect, the DB9000 Family of TFT LCD Controllers IP Cores & Reference Designs can connect via Qsys. Likewise, the DB9000 family member with AXI interconnect — the DB9000AXI — can connect via the AMBA AXI.interconnect fabric to a ARM® Cortex™-A9 processor within the Cyclone V and Arria® V SoC FPGAs.

Digital Blocks TFT LCD Controller reference design enables you to accelerate the design-in of TFT LCD panel displays in your system. The reference design centers on the Digital Blocks DB9000AVLN TFT LCD Controller intellectual property (IP) core, which is available in netlist or VHDL/Verilog HDL register transfer level (RTL) formats.

The DB9000AVLN core contains an Avalon® Memory-Mapped system interconnect for interfacing to the Nios® II embedded processor and SDRAM or SRAM controllers (either memory can serve as the frame buffer). Software supplied with this reference design runs on the Nios II embedded processor to place an image in the frame buffer memory and invokes the DB9000AVLN core to drive the LCD panel.

Using the Intel® Quartus® Design Software, you can instantiate the TFT LCD Controller reference design in a Cyclone®, Cyclone® II, or Cyclone® III FPGA development kit. See the Demonstrated Intel® Technology section for a complete list of supported Intel® FPGA development kits.

You can connect your LCD panel to the Intel FPGA development kit with the fabrication of an appropriate cable. Please contact Digital Blocks for more details.

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.”

TFT LCD panels always have a controller in there which is a CoG (chip on glass) type IC planted on to the panel to drive the rows and columns. The chip has referenace values and tables to drive the display to get the desired contrast and bias voltage needed to control the LCD pixels properly. Incorrect values can cause the panel to look low contrast and weak, or in the other extreme case cause permanent damage to the panel.

The CoG controller IC datasheet usually specifies a range of VGH, VGL, VCOM and AVDD values as absolute maximum rating. As a designer you must ensure that those values are not exceeded. Because the current draw is very little on VGH, VGL and VCOM, overshoots can be a problemin poorly designed circuits.

In addition to this, the LCD manufacturer configures the CoG LCD controller to use certain bias voltages that match the LCD panel characteristics (all LCD panels are not exactly the same). Here is an example from a 7″ display datasheet (ER-TFT07-2) with RGB interface.
