reference design for tft lcd panel in stock

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.

The adoption of LCD technology in vehicular displays has happened quite quickly and smart displays have by now pretty much replaced the mechanical dashboards of yesteryears in cars. In an interview with our team, Rei Tjoeng from Sharp Devices revealed some interesting information regarding automotive-grade LCDs, the recent trends, and specific characteristics that make some LCD displays different from the others available in the market.

A. Adoption of TFT in 2-wheeler cluster applications has increased in a big way. The global automotive industry is widely believed to be on the cusp of tremendous change in terms of manufacturing, sales, and the overall business model, owing to the rapid advances in new-age technologies such as autonomous driving, augmented reality, and big data.

Advanced driver-assistance systems (ADAS)—such as parking assistance, forward collision, lane-departure warnings, and blind-spot monitoring—are frequently hailed as the technologies that will usher us into an age of autonomous transportation, but drivers are still either untrusting or too trusting of these features. This has led to an evolution of sorts in the in-car user experience interfaces, and more so with the way automotive display makers are developing new products.

The future for ergonomic conformal displays, display-based dash, central console, in-door wing mirrors, and transparent displays that offer unobtrusive visual information during journeys is bright. Head-up displays are fast gaining popularity as an ideal interface for disseminating crucial information such as navigation messages, vehicle speed, and warnings.

A. Yes, reflective LCDs, which use ambient light to reflect in order to read. In 2W cluster applications, where TFT is exposed to direct sunlight, readability is a major issue. Sharp Reflective LCD is a solution as visibility is crystal clear without any glare and is available in colour too. Equipped with a backlight, it can be used at night also.

Normal TFT has to pump more power through the backlight, which results in more power consumption and backlight life also gets affected to a large extent. This reflective LCD consumes very little power and could be the best fit-in product for the EV segment.

A. The market is now shifting to large-size TFT displays in the automotive segment. These displays are automotive-grade LCDs and are tested for shock, vibration, high and low temperature, etc. For more protection and safety, glass bonding is done over TFT. Glass bonding with a cover glass on the LCD protects it from shock, as the hardened adhesive behind the glass acts as a shock absorber. Shakes and shocks are less likely to damage the display and glass, making this an important benefit for transportation applications. In the unlikely event that the glass is damaged, shards of broken glass will remain stuck to the optical adhesive.

A. Reflective LCD and Progressive Super View are the two technologies which are effective under high ambient light. In progressive super view technology, internal and external reflection is cut down, which results in a clear view without glare. And the beauty of this technology is that it happens without pumping more power from the backlight. This helps in more lifetime of the backlight and less power consumption.

Reflective LCD is another technology that uses ambient light to reflect in order to read, hence there is more clarity under sunlight and very less power is needed. It is more beneficial for EV applications.

A. Automotive-grade LCDs have strict requirements. The LCD must remain working during the extreme environment, for example, Indian summertime. For example, our LCDs are tested for storage temperature of -40 to 95°C and operating temperature of -30 to 85°C.

From a design engineer’s perspective, what are the top factors—besides the obvious ones like price, size, brand, after-support, etc—that should be borne in mind while selecting the right LCD panel?

There are a few LCD specs the design engineers need to consider at high priority when they select the LCD. The first specification will be the screen size and aspect ratio. The aspect ratio is the ratio between the length and width of the LCD. Some common ratios are 4:3, 5:4, 16:9, and so on. Of course, sometimes marketing people will also consider these specs as they will affect the whole outlook and design of the product.

Then the engineer may need to consider the LCD’s resolution and interface, whether they are matching with the motherboard. If the product is a semi-outdoor or outdoor application, then the engineer needs to also check the LCD’s brightness and operating temperature range, because these are very important specs if the product is located in the sunshine.

A. The smartphone has become very popular in recent years and it is influencing the engineers’ design. We saw some EV companies use the smartphone LCD as the cluster or GPS display for their first-generation products. The smartphone LCD is nice but, unfortunately, it is not designed for automotive applications, especially not for 2-wheeler outdoor usage. When the 2-wheeler is under the sunshine, the driver can barely see anything from the smartphone LCD. And, also, the smartphone LCD’s lifetime becomes much shorter under the automotive application scenario.

A. Sharp Singapore has been in this region for many years. We understand our customers. First, our team will get the customer’s requirements from both the marketing and engineering sides. We will check the customer’s motherboard’s graphics capability, display interface, and other necessary technical details. We will propose the best suitable LCDs to the customer and explain the reason. We will explain what we observe from the market trend and help the customer to know the best options.

LCD samples and demo kits are available for the engineers to see the actual performance. There is also technical support available to help the design engineers to evaluate the LCD and design-in the LCD.

Q. Do you have some form of sampling programme for them to receive samples during their prototyping stages? Do you have development or evaluation kits for your LCD displays?

A. Sharp Singapore understands that samples and evaluation kits are important in the project’s early stage. Evaluation kits are available for the engineer to evaluate the LCD performance during the proof of concept stage. Then we will provide sample LCDs for the customer’s prototype builds.

A. We have salespersons stationed in India at New Delhi and Bangalore. They are working closely with the customers’ design engineers. There are technical support persons in Singapore and Japan. Our Indian team can support the customer onsite and bridge as technical person effectively between India and Singapore.

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

The speed of playing all the GIF files are edited and we made them faster or slower for better understanding. The speed of motions depends on the speed of your processor or type of code or size and thickness of elements in the code.

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.”
