tft lcd controller vhdl factory

Not long ago, we published some articles about controlling different kinds of displays, using your FPGA. On a VGA screen, on a small LCD screen, on a PSP LCD or even for the old, but nasty-analog-signaled NTSC system.

And today, we share with you another great tutorial on how to control a LCD TFT, that takes advantage of the ability of a FPGA to fully control what happens on every single clock cycle.

You may think, well, another LCD tutorial, more on the same…And you will be wrong. There are no identical systems. Each one has its own features which make it unique, and we want you to know them.

This is a very well explained tutorial that gives you all the files you will need to successfully implement it: schematics, VHDL code files, Project files, datasheets of the display…Everything!

In addition the author takes some extra time to explain what really matters about this project and what makes it different from any other “How to control your LCD screen with your FPGA”. To properly control a TFT display you need two specific timed signals: DCLK (Pixel Clock) and DE (Data Enable). Why the code lines that control these two signal are coded the way they are is carefully explained in the article so you don´t want to miss it. Understanding this will make you capable of playing with any other TFT screen you may find.

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.

TFT-LCD technology is based on semiconductor IC manufacturing processes, and is unique in that it uses glass substrates rather than traditional silicon wafers. For the TFT manufacturing process, thin film formation, such as CVD and PVD processes, is a very important part. The ODF process has been developed for the assembly of color filters and TFT substrates, and is used in large size LCDs.

First of all, the movement and arrangement of liquid crystal molecules need electrons to drive, so in the carrier of liquid crystal – TFT glass, there must be able to conduct the part to control the movement of liquid crystal, here will use ITO (Indium TIn Oxide, transparent conductive metal) to do this thing. ITO is transparent, also known as thin film conductive crystal so that it will not block the backlight.

The different arrangement of liquid crystal molecules and the rapid movement changes to ensure that each pixel accurately display the corresponding color, and the image changes precisely and quickly, which requires precision control of the liquid crystal molecules. ITO film requires special processing, as if printed circuitry on a PCB board, drawing conductive lines throughout the LCD board.

For array panels with back-channel etched TFT structure.The main process can be divided into 5 steps (5 lightings) according to the sequence of the layers to be made and the interrelationship between the layers.

The process includes: PECVD triple layer continuous film formation, island lithography, island dry lithography and other processes. After these processes, the final amorphous silicon island for TFT is formed on the glass substrate. The graphics obtained after the process is completed are shown in the following figure.

Specific processes include: S/D metal layer sputtering into a film, S/D lithography, S/D wet lithography, channel dry lithography and other processes. After these processes, the source, drain, channel and data lines of the TFT are finally formed on the glass substrate. At this point, the TFT has been produced. The graphics obtained after the process is completed are shown in the following figure.

The process includes PECVD, photolithography, and dry lithography of vias. After these processes, the final TFT channel protective insulation layer and guide through the hole are formed on the glass substrate. The graphics obtained after the process is completed are shown in the following figure.

Color filters can be produced by various methods; photolithography is a typical method. In photolithography, color filters are produced by exposing a glass substrate coated with a photographic color resist through a photomask. The resist is hardened to form the RGB pattern of the LCD.

When making LCD panels it is impossible to produce them one by one, which is too inefficient, so multiple pieces are processed at once and separated by cutting.

In between of these you will see a small green connector board, which is our own 7-inch LCD Breakout board with the required switch-mode power supply for powering the LED backlight, together with the interface connector with the 18-bit color signals, Pixel Clock, Data Enable and PWM.

Where the TDEH and TDE are definitions as found in the datasheet. In the top of our VHDL code all these timing definitions has been programmed as constants:

The main part of the architecture is the uBlaze microcontroller. It is connected to many GPIO peripherals for controlling LEDs, 7Segment, Image RAM content and for reading both from DIP Switches and from graphics controller the current line and column for debug. To uBlaze is connected also the interrupt controller as a peripheral. Push buttons and internal timer are connected to interrupt controller.

Another important part of the architecture is Image RAM memory. The RAM memory is described by a vhdl code and is a simple dual RAM memory. This RAM contains the image graphics controller will display on LCD. The size of the image stored in RAM memory depends on the virtual size of the LCD. The VmodTFT LCD has 272 lines and 480 columns and a colour depth of 8 bits for each primary colour. The number of cells of the RAM memory is 130560 and each one contains the data on 24 bits. Therefore the size of the LCD is roughly 3Mb. It requires 96 BRAM block out of 135 the Artix7 FPGA has. The Image RAM memory is interfacing with Pixel Controller GPIO peripheral of uBlaze. This peripheral writes on RAM the value of each pixel. This is connected to port A of uBlaze. The port B of the RAM is connected to graphic controller.

The next part of the system architecture is graphics controller. The latter accesses the Image RAM Port B with the signal address and the Port B output is connected to its RGBin input. The graphics controller is also connected to the VmodMIB via the Pmod connectors in order to set each pixel value of the display.
