As the first in the world we do provide TFT displays with 3.2", 4.3" and 7", which are immediately running and do provide from the first minute the full functionality. These displays do require a single supply 5V= (EA eDIPTFT32: 5V= or 3.3V=) and an interface RS-232, I²C or SPI only.

Like all EA DIP modules, the EA eDIPTFT displays are simply inserted in the PCB and soldered in place. No screws, distance sleeves or cables are required, thus saves material cost and simplifies construction. This results in a saving of between 2 and 4 minutes per module during assembly!

For a standard screw mounting (e.g. together with the optional mounting bezel), the displays do come with 2 additional mounting clips for easy screw mounting.Communication via serial interface (RS-232, I²C, SPI)

Additionally to the well-proved versions with a resistive touch panel currently we do provide 2 displays with 4.3" and 7" alternatively equipped with a capacitive touch panel: EA eDIPTFT43-ATC (4.3") and EA eDIPTFT70-ATC (7").

The advantage is more transperency that leads for both sizes to again more brightness and a very contrasty display. The surface is made of glass which is hard profen against scratch, it is hygienic and resistant against all cleaning stuff. The design with its black frame grants your equipment a valuable, modern optic.

An essential detail with industrial applications ist the usability with and without hand gloves. Even when the display is put behind a 3mm glass plate it may be operated perfectly.Technology

This is a 5" Raspberry Pi LCD touchscreen with 800*480 resolution and 108×64.8mm display area. The product supports Raspberry Pi DSI display interface and comes with a capacitive touch panel on its screen and supports 5 touch points.

The special holes design on the back of the screen is convenient to directly install the Raspberry Pi in the product. There is no need to provide external power for the touchscreen as the Raspberry Pi power supply is adopted. In addition, the screen supports hardware backlight adjustment. The function can be realized by turning the potentiometer on the back of the display.

The μLCD43(GFX) is an intelligent graphics display that harnesses the power of Active Matrix LCD (TFT) technology to deliver a diverse range of features in a single, compact cost effective unit. Embedded at the heart of the design is the PICASO-GFX2 processor.

4DGL allows the developer to write applications in a high level syntax similar to popular languages such as BASIC, C and Pascal and run it directly on the PICASO-GFX2 processor embedded in the uLCD-43 module. It allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, Graphics LCD Display, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uLCD-43 module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.

Display size, contrast, color, brightness, resolution, and power are key factors in choosing the right display technology for your application. However, making the right choice in how you feed the information to the display is just as vital, and there are many interface options available.

All displays work in a similar manner. In a very basic explanation, they all have many rows and columns of pixels driven by a controller that communicates with each pixel to emit the brightness and color needed to make up the transmitted image. In some devices, the pixels are diodes that light up when current flows (PMOLEDs and AMOLEDs), and in other electronics, the pixel acts as a shutter to let some of the light from a backlight visible. In all cases, a memory array stores the image information that travels to the display through an interface.

According to Wikipedia, "an interface is a shared boundary across which two separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. Some computer hardware devices such as a touchscreen can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system.” In other words, an interface is something that facilitates communication between two objects. Although display interfaces serve a similar purpose, how that communication occurs varies widely.

Serial Peripheral Interface (SPI) is a synchronous serial communication interface best-suited for short distances. It was developed by Motorola for components to share data such as flash memory, sensors, Real-Time Clocks, analog-to-digital converters, and more. Because there is no protocol overhead, the transmission runs at relatively high speeds. SPI runs on one master (the side that generates the clock) with one or more slaves, usually the devices outside the central processor. One drawback of SPI is the number of pins required between devices. Each slave added to the master/slave system needs an additional chip select I/O pin on the master. SPI is a great option for small, low-resolution displays including PMOLEDs and smaller LCDs.

Philips Semiconductors invented I2C (Inter-integrated Circuit) or I-squared-C in 1982. It utilizes a multi-master, multi-slave, single-ended, serial computer bus system. Engineers developed I2C for simple peripherals on PCs, like keyboards and mice to then later apply it to displays. Like SPI, it only works for short distances within a device and uses an asynchronous serial port. What sets I2C apart from SPI is that it can support up to 1008 slaves and only requires two wires, serial clock (SCL), and serial data (SDA). Like SPI, I2C also works well with PMOLEDs and smaller LCDs. Many display systems transfer the touch sensor data through I2C.

RGB is used to interface with large color displays. It sends 8 bits of data for each of the three colors, Red Green, and Blue every clock cycle. Since there are 24 bits of data transmitted every clock cycle, at clock rates up to 50 MHz, this interface can drive much larger displays at video frame rates of 60Hz and up.

Low-Voltage Differential Signaling (LVDS) was developed in 1994 and is a popular choice for large LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is a great solution because of its high speed of data transmission while using low voltage. Two wires carry the signal,  with one wire carrying the exact inverse of its companion. The electric field generated by one wire is neatly concealed by the other, creating much less interference to nearby wireless systems. At the receiver end, a circuit reads the difference (hence the "differential" in the name) in voltage between the wires. As a result, this scheme doesn’t generate noise or gets its signals scrambled by external noise. The interface consists of four, six, or eight pairs of wires, plus a pair carrying the clock and some ground wires. 24-bit color information at the transmitter end is converted to serial information, transmitted quickly over these pairs of cables, then converted back to 24-bit parallel in the receiver, resulting in an interface that is very fast to handle large displays and is very immune to interference.

Mobile Industry Processor Interface (MIPI) is a newer technology that is managed by the MIPI Alliance and has become a popular choice among wearable and mobile developers. MIPI uses similar differential signaling to LVDS by using a clock pair and one to eight pairs of data called lanes. MIPI supports a complex protocol that allows high speed and low power modes, as well as the ability to read data back from the display at lower rates. There are several versions of MIPI for different applications, MIPI DSI being the one for displays.

Display components stretch the limitations of bandwidth. For perspective, the most common internet bandwidth in a residential home runs on average at around 20 megabits per second or 20 billion 1s and 0s per second. Even small displays can require 4MB per second, which is a lot of data in what is often a tightly constrained physical space.

Take the same PMOLED display with the 128 x 128 resolution and 16,384 separate diodes; it requires information as to when and how brightly to illuminate each pixel. For a display with only 16 shades, it takes 4 bits of data. 128 x 128 x 4 = 65,536 bits for one frame. Now multiply it by the 60Hz, and you get a bandwidth of 4 megabits/second for a small monochrome display.

This article about TFT display interfaces was written by Julia Nielsen. Julia Nielsen is a jack-of-all-trades writer, having written for newspapers, magazines, websites, and blogs for the last 15 years. When she’s not dabbling in the written word, she’s spending time with her beautiful granddaughter. She loves to hear from readers, especially when they offer chocolate.

Display technology has evolved at lightning speed for the last number of years, as opposed to when even the most sophisticated products incorporated numeric or segment displays and alphanumeric or character display technology. The same products also required buttons which have been replaced with resistive and capacitive touch panels.

When color TFT (Thin-Film Transistors) first came onto the stage, they created a buzz in the tech world that hasn’t stop buzzing since. TFT utilizes a type of display that controls each pixel with a transistor, allowing it to individually address each location.

As TFT yields improved with mass production, manufacturing, as well as healthy competition, TFT displays have soared in production performance and dived in price. Because of this, TFTs are considered the de facto standard of displays that boast of full color, brightly backlit (high NIT counts), high video speeds, better viewing angle, specifically for mobile devices and other small devices needing clear displays, such as phones, watches, security systems, and the like.

OLED (organic light-emitting diode) are increasing in popularity, but are still second to TFTs. Much of this is due to the long lead time and shorter half-life of the OLED displays. Although we offer OLED technology, we recommend TFT for the majority of the new design requests we receive.

There are several types of TFT display interfaces which have been designed in the last number of years for all variations of screen size, including LVDS, (Low-Voltage Differential Signaling) parallel, SPI (Serial Peripheral Interface) and I2C or I²C (aka I squared C) display.

Low-voltage differential signaling was first designed in the early 1990’s and has seen its popularity mainly in LCD-TVs, industrial cameras, notebook and tablets, and communication systems. LVDS is a technical standard that specifies electrical characteristics of a differential, serial communications protocol, which allows the operation of low power, but very high speed using inexpensive twisted-pair copper cables.

LVDS is a differential signaling system, meaning it transmits information as the difference between the voltages on a pair of wires. Its popularity comes from the benefit of reducing noise levels and low power consumption, which results in even more benefits, such as lower heat dissipation and longer battery life; and because the differential drivers can be included on the LVD interface, smaller parts count, lowered parts cost, and increased reliability is a win-win for businesses and consumers.

Commercial and military, as well as aerospace applications also use LVDs in their products for a robust, long-term solution for high-speed data transmission needs. Flat panel displays, printers, digital copiers, and even cell phones incorporate LVDs to provide an excellent display quality. There are different types of LVDS protocols. When looking for the right LVDs, consider data rate, operating temperature range, and supply voltage, using these filters.

Note: Most TFT displays will operate down to -30C without the need of a heater. OLEDs will operate down to -40C without a heater, but OLEDs that are larger than 3.5” are much more expensive and have a longer lead time than TFTs.

Parallel interface or parallel port is a type of display interface found on computers for connecting peripherals. In the past, most people associated a ‘parallel’ interface with a printer port. This type of interface refers to a multi-line channel with each line capable of transmitting several bits of data on each simultaneously (bi-directional) or parallel to each line.

Newer PC’s have eliminated parallel interfaces in exchange for fire wire, USB2 and USB3. Parallel interfaces are still the most common for several LCD technologies such as character and monochrome graphics.

Parallel interface is nothing new, going back to the beginning of the 1970’s in its development and implementation. The first printer to use the interface was the Centronics 101 model printer, which became the standard at that time. But because a number of cables were required, Dataproducts and other developers had to create up to 50-pin connectors.

Fast forward to 1981 and IBM introduced their computers and printers with a 25-pin connector on the PC end and a 36-pin connector on the Centronics printer, thus the parallel interface had evolved to using both systems. In 1987, IBM introduced a bidirectional parallel interface. Since then, the parallel interface has evolved, with other companies developing their own, with even more parallel ports, including scanners.

Since technology has advanced exponentially in the last decade, so has the parallel interface, evolving to include supercomputers that allow for high-performance interfaces and network storage devices. These super performance display interfaces are capable of transferring billions of bits of data per second over short distances on local area networks. Graphical printers, along with a variety of other devices have been designed to communicate with the parallel ports including:External modems

Some of the early MP3 players and digital cameras also used a parallel port connection for transferring songs to a device, so you can see how far back the interface has been utilized in electronics.

Serial Peripheral Interface allows the serial (one bit at a time) exchange of data between two devices. A master, which controls one or more devices. Each device has its own slave connection. The master can interface with multiple slaves independently.

The term SPI was coined by Motorola and is typically used in communication systems between the CPU (Central Processing Unit) and peripheral devices (Any computer device not part of the essential computer, but situated close by). Serial interfaces have an advantage over parallel ones, that of simpler wiring. They can also have longer cables since there is much less interaction or crosstalk among the conductors in the cable. Many types of devices use SPI, such as:Shift registers

A key difference between SPI and Parallel is that with a serial interface, it only allows for transferring data one bit at a time but decreased the pins required, as opposed to the parallel, which allows multiple bits at a time, but requires more pins (8 data pins and 3 controllers). The downside with a SPI is that you can’t read from the display you can only write on it, and it’s typically slower.

I²C, Inter-integrated Circuit pronounced I-squared-C or I-2-C for a less technical term, is a serial protocol for two-wire interface to connect low-speed devices like micro-controllers, EEPROMS, A/D and D/A converters, I/O Interfaces and other peripherals in embedded systems. It was designed to allow easy communication between components which reside on the same circuit board. I²C only requires two wires: SCL (serial clock) and SDA (serial data). It is a multi-master, multi-slave, single-ended, serial-computer bus, (a communication system that transfers data between components inside a computer or between computers) and was invented by Phillips Semiconductor.

SMbus, (System Management Bus) developed by Intel in 1995, is a subset of I²C, which defines the protocols more strictly. Modern systems employ rules and policies from SMbus, sometimes supporting both systems, requiring minimum reconfiguration. Since 1982, there have been seven revisions to the I²C interface, and has evolved, as every other interface, with new technology always on the horizon.

As far as these two TFT display interfaces, we find that SPI is more popular than I2C when designing a custom LCD. We get hit with questions such as:Why is SPI more popular than I2C?

TFTs and OLEDs are standard, off-the-shelf displays that come with the interface already chosen for you. In many of the TFTS that Focus Display Solutions offers, the built-in controller allows the user to select from multiple display interfaces. Including RGB (Red, Green, Blue).

As a general rule, the larger the display the better it is to choose a LVDS interface since it transfers data so quickly. LVDS is more expensive than SPI, I2C, RGB and parallel.

6) Power on the Raspberry Pi and wait for a few seconds until the LCD displays normally. And the touch function can also work after the system starts.

On December 2, 2021, the Raspberry Pi OS was divided into two branches, the Buster branch and the Bullseye branch. The Buster branch is a continuation of the old system and is more stable. The Bullseye branch added some new features, using open source libraries and new interfaces. Since the current Bullseye branch has just been released shortly, it is not stable yet. If you are an industrial user, it is strongly recommended to use the Buster branch.

Connect the Raspberry Pi camera to the CSI interface of the Raspberry Pi, power on the Raspberry Pi again, and after the system boots, execute the following command:
