fpga lcd display manufacturer

If you’re reading this article on a desktop or laptop computer, you’re probably staring at millions of pixels on a TFT LCD display. TFT became a dominant technology due to its picture quality and fast response times, but it’s not the only way to build an LCD. There are cheaper technologies, such as STN and its color variant, CSTN. They’re rarely used nowadays, but [Wenting Zhang] had one lying around and wanted to take a crack at driving it.

[Wenting] instead grabbed an FPGA and got to work. Driving displays can be taxing for small microcontrollers, so an FPGA is always a great choice when working on such projects. They’re easily capable of generating whatever weird and wacky signals are required, and can generate many such signals in parallel without breaking a sweat.

The life span of traditional LCD screens is between 40,000 and 60,000 hours, and the more recent popular OLED screens have a life span of about 30,000 hours. If you look at the phone for an average of 3 hours a day, it can also last 10,000 days, or 27 years, which is far more than the average user’s replacement cycle.

OLED display technology, which uses a very thin coating of organic material and a glass substrate (or flexible organic substrate) that emits light when an electric current is passed through it.

Nowadays, OLED screen has become the standard for high-end smartphones, compared with the traditional LCD technology, it is not only thinner, lower energy consumption, high brightness, can display pure black, faster response time, but also can be made into a curved screen, giving people a different visual impact

Why under-screen fingerprint recognition can only be used in OLED screen? This is because it is relatively “soft”, OLED in the construction of only two layers of thin film and glass or plastic substrate, and through the OLED material self-lighting characteristics, can be without backlight module and color filter, also do not need the general LCD panel filling liquid crystal process, can achieve 0.5-1.8mm thickness. Nowadays, most of the under-screen fingerprint recognition is optical fingerprint program, so relatively in the use of optical fingerprint program, OLED screen will be more suitable.

Why can’t under-screen fingerprint recognition be used in LCD screen? This is because it is relatively “hard”, the working principle of LCD is mainly composed of two parallel glass plate, between the two layers of glass plate and then by the liquid crystal layer and polarizer, color filter layer and so on material composition. In simple terms, LCD is the need for backlight irradiation to display, so is the result of LCD screen than OLED screen thicker, light transmission is weaker, not conducive to the use of under-screen fingerprint identification.

Since OLED screen can use under-screen fingerprint recognition, why do not all cell phone manufacturers use OLED screen? This involves the advantages and disadvantages of LCD screens and OLED screens.

LCD screen, although temporarily can not use under-screen fingerprint recognition, but, LCD screen is also the advantages of OLED can not be comparable, there is a natural DC dimming more eye protection, color is also natural, drawing people prefer LCD, screen life compared to OLED long, but also not easy to change color, also do not have to worry about using a long time after the problem of burning screen, which is also the reason why LCD loyal users like it.

In addition, LCD screen does not stimulate the human eye, will not cause eye fatigue, especially open eye protection mode filtering blue light, less damage to the eyes. oled screen will leave residual shadows, eye damage, even dimming can not be completely avoided.

Adding a character liquid crystal display (LCD) to an FPGA project is a simple and inexpensive way to get your project talking. In this post I discuss interfacing an FPGA with garden-variety generic 1602 LCD like the one pictured nearby. These alphanumeric displays include an integrated HD44780-compatible controller with a parallel interface that enables you to send data in ASCII format one byte at a time. The output is two lines of 16 characters each on a fixed dot matrix grid. They"re cheap as chips (as my English friends say) and perfect for displaying measurements, results of calculations and any other simple messages.

My objective here was to develop a reusable Verilog module that could be dropped in to multiple FPGA projects and handle the low-level communication with the LCD. As part of an effort to make the Verilog as platform independent as possible, I developed and tested the module on two different boards. First is an Olimex ICE40HX8K-EVB board using the Project Icestorm workflow. (I discuss the board and Project Icestorm in an earlier post here: iCE40 and the IceStorm Open Source FPGA Workflow.) Second is an Arrow BeMicro CV board featuring an Intel/Altera 5CEFA2F23C8N Cyclone V, developed using Quartus 15.0.

The Hitachi HD44780 LCD controller has been around for decades. I don"t have an exact year of release, but a quick search has it turning up in catalogs and magazines by the early-to-mid-eighties. Somewhere along the line Hitachi stopped making them, but compatible replacements exist including the Sunplus SPLC780, the Samsung KS0066U and the Sitronics ST7066U. While not all small text displays are HD44780-compatible, the instruction set and interface for the controller have become something of a standard.

Both 5v and 3.3v displays are available. While it"s technically possible to interface a 5v version, I don"t have any appetite for letting 5v devices get too close to the 3.3v IO pins on my FPGA board, so I"m of course using a 3.3v version.

Configuring these displays is reasonably easy and there is a lot of raw material online to help get a project started. The fact that they"ve been around so long means there are tutorials available for every imaginable microcontroller. They"ve even shown up on some Xilinx and Altera training and development boards over the years.

I think I"ve got the timing pretty-well demystified and I"ll provide some detail further in this posting. But at a high level I can say that it"s very helpful to remember that the timing requirements from the datasheets are minimum requirements. You don"t have to try to achieve these exact time values. In fact, unless you have an application that needs to squeeze every nanosecond of performance out of the display, you can save yourself a lot of headache by building in some nice buffer around the minimum timings.

Five of the pins are dedicated to power, including a contrast control for adjusting the backlighting. Vss (ground) and Vdd (positive supply) are the main power for the logic. A and K are positive and ground to the backlight. The V0 pin adjusts the contrast to the display. Most setups use a 10k potentiometer on the contrast pin. You can tie it straight to ground through a 1K to 4K resistor, but the contrast is pretty sensitive and if you use a potentiometer you"ll probably be happier.

Three of the pins are dedicated to control signals. The RS (register select) is used to indicate whether data on the bus is a character (RS=1) or an instruction (RS=0). The E (enable) pin is toggled on and off to enter the data. The R/W (read/write) pin switches between read (R/W=1) and write (R/W=0). R/W is frequently tied to ground and the LCD is treated as a write only device. (My setup has R/W tied to ground and the FPGA and Verilog ignore it.)

The remaining eight pins are the data bus. As noted, data on the bus can either be a character or an instruction. Characters include standard ASCII codes for the numbers 0-9, letters a-z and A-Z, and many of the general standard ASCII punctuation and symbols such as !, ?, #, and $. Beyond those characters, the LCD will have additional characters depending on the manufacturer of the board and the version of the controller. The controller can also manage user-defined custom characters.

At the highest level, controlling the display can be seen as a simple process of pushing a sequence of instructions and characters through by setting up the RS pin and the DB0-7 pins one byte at a time while toggling the E pin on and off to tell the controller as each byte is ready.

Before data or instructions can be written to the controller, an initialization sequence must be executed that configures the controller and makes sure it"s ready to receive input. The HD44780 does run through a version of the initialization when it first powers up, but there are a few problems with that routine. The hardware initialization is somewhat fragile and very dependent on the circuit"s power supply. It also sets the controller to a default that might not be the desired state. Best practice looks to be including initialization in the design. For my own use, I have the FPGA drive the full initialization sequence on startup and have also tied the sequence to a push button on my board for a soft reset.

Steps 2,3 and 4 all load the same instruction to the controller. Once RS and D[0-7] are set on the FPGA it is not necessary to keep resetting them - all that is needed is to bring the enable pin high and low at the appropriate times.

Step 8 configures the Entry Mode which determines what the controller does as it receives new characters. The setting here fills in text from left to right while the display itself stays still. There are multiple options.

To implement the initialization sequence, I again use a state machine to step through the process. I actually combine the initialization and operating phases into one 26-step state machine (code further below). Of course, my solution is only one of many possible approaches. In researching for this project and hunting up examples of FPGAs driving LCDs, I found tremendous variety in the ways that people setup their state machines and manage the timing. It"s certainly worth looking around for inspiration.

The final steps in making a usable LCD driver involve reconfiguring the module to process incoming data (rather than just displaying the letter "H" in the notional code) and establishing some type of handshaking.

Slightly trickier is the idea of establishing communication between the LCD driver module and the hypothetical other module producing the data. The LCD driver needs to know when there is fresh data available to be written to the display. Likewise, since the LCD driver needs considerable time to process a byte of data, the data producing module needs to know when the LCD driver is ready. In the code below you"ll see that I addressed these two parallel needs with a "data_ready" input bit and a "busy_flag" output bit.

In states 23-25, which comprise the portion of the state machine that actually writes data to the LCD, state 23 will idle until the data_ready bit goes high. Once the bit goes high, the module sets its own internal tracking bit called "start" to high, sets the busy_flag output high, and starts processing the incoming data. The busy_flag and start bits remain high until the process is complete.

Below is the Verilog code for the full LCD driver module. This module has been tested with a hello world demonstration. I"m not displaying the full demo, but you can download it here: Verilog LCD Hello World Demonstration. The demonstration adds a ROM with the ASCII codes for Hello World and a controller that interfaces with the LCD module to feed one character at a time.

Project IceStorm is the first, and currently only, fully open source workflow for FPGA programming. Here, the software and hardware are discussed and a small sample project implemented.

The panel uses a 30-pin connector (which plugs into a port on the mainboard). The 30 pin connector then splits into two: one set of wires goes to the inverter for the backlight, and the other set containing the LVDS & EDID wires goes to the PCB on the LCD panel.

FPD-Link is a high speed digital video interface that is used to transmit video from the GPU (laptop/tablet/TV motherboard) to the display panel. FPD-Link uses LVDS (Low Voltage Differential Signalling), which transmits bits of data as differences in voltages between the 2 twisted pair wires. LVDS reduces the generation of electromagnetic noise, and due to the twisted pair cables and differential signalling, is resistant to common mode noise as well. Note that most literature refers to FPD-Link as "LVDS", although LVDS is just the electrical standard, and FPD-Link defines the signalling/packet structure.

From what I"ve read here and here, FPD-Link is being phased out and replaced by embedded Display Port. As panel resolutions increase, LVDS requires multiple channels (eg at 1080p60, FPD-Link requires around 4 or 5 channels @ ~135Mhz), but eDP can do with only 1 or 2 channels, and much higher signalling rates (1.6, 2.7, 5.4 Gbits). eDP would be interesting to try, but it would need a more expensive FPGA that has Gigabit transceivers.

I then turned to the the laptop mainboard, since if there was a LVDS transmitter, I could find a way to route the signals from the FPGA to the transmitter. I managed to find schematics for the laptop, but the LVDS signals were being routed directly from the Intel Chipset. I checked the datasheet for the chipset (an Intel 965 Express), and it confirmed that the Chipset was infact generating LVDS. This meant that it wouldn"t be possible to tap the data lines of any LVDS transmitter, and I would need to find a way of generating it.

I was searching for LCD addon boards (PMOD, FMC etc.) to see how the signalling & conversion is implemented, when I found a forum post detailing how Avnet"s 7-inch Zed Touch Display Kit generates a LVDS signal using the Zynq"s TMDS33 outputs.

The LCD panel uses a CFL backlight (it"s from an old laptop), so my first task was to turn on the backlight. I referred to the pinout of the connector, and the schematics of the laptop main board to try to figure out how it was being controlled.

The next blog post LCD panel + FPGA with an HDMI sink = External Display will continue from here: implement a HDMI sink, and display the received video on the LCD panel.

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.
