2.2 inch 240*320 ST7789V 8bit MCU interface TFT LCD display module with touch screen panel LM022TQ02NS is a 2.2 inch TFT LCD Display.The model is featured with 18-BIT RGB/MCU interface. It can be used in signal analyzers or bench top laboratory equipment, handhold microscope and other handhold devices.

A TFT LCD display module consists of a TFT LCD panel, one or more COG (chip-on-glass) or COB (chip-on-board) driver ICs, a backlight, and an interface. Several TFT display interface technologies exist today. Picking the right interface depends on specific end-product concerns. There are several types of TFT display interfaces which have been designed in the last number of years for various screen sizes, including LVDS, (Low-Voltage Differential Signaling) parallel, SPI (Serial Peripheral Interface) RGB and so on. Here is an overview of these display interfaces to give you a better idea of the variety of TFT LCD displays that are taking center stage.

SPI LCD Interface: Serial Peripheral Interface allows serial (one bit at a time) exchange of data between two devices. It has an advantage over parallel ones, that of simpler wiring. SPI also can have longer cables, since there is much less interaction or crosstalk in the cable. The downside of SPI is that you can"t read from the TFT LCD display, you can only write on it and it is slow. That"s why you normally see smaller TFT LCD screens use SPI.

MCU Parallel Interface: Many modern MCUs have built-in LCD controller function. There are two types that are commonly used, 6800 and 8080. Generally, MCU/Parallel interface consist of data signal(4/8/9/16 bits) and control signal. MCU interface is simple, but requires display RAM.

RGB Interface: RGB interface is a special kind of parallel interface. It requires no display RAM. MCU directly updates the TFT screen, sending Red Green & Blue sub-pixel data (16/18/24 bits) and timing signals. RGB interface provides high speed communication to TFT LCD, but it needs more data wires and controlling is more complex.

LVDS Interface: Low-voltage differential signaling is an electrical digital signaling standard. Devices with LVDS interface can communicate at very high speeds over inexpensive twisted-pair copper cables. It is much less susceptible to EMI and crosstalk issues, allowing the transmitting device to be located farther from TFT LCD display.

UART/RS232/RS485: These serial interfaces are used in Topway"s Smart TFT LCD display module. Universal Asynchronous Receiver/Transmitter (UART) is a block of circuitry responsible for implementing serial communication. Essentially, the UART acts as an intermediary between parallel and serial interfaces. On one end of UART is a bus of eight-or-so data lines (plus some control pins), on the other is the two serial wires – RX and TX.

HDMI Interface: High Definition Multimedia Interface is a connector and cable definition that supports high-quality and high-bandwidth streams of video and audio between devices.

MIPI DSI: MIPI Display Serial Interface defines a high-speed serial interface bewteen host processor and display module. The interface facilitates a high performance, low power and low EMI way to render brilliant color for the most dempanding image and video scenes.

The parallel interface typically controls the LCD via 8 data pins and 3 control lines. The control lines used are Enable (E), Register Select (RS), and Read/Write (R/W). RS tells the LCD module if the information being sent is an Instruction or Data. The Enable tells the LCD module that the data or instruction in the register is ready to be interpreted by the LCD Module. Some controllers may have more than one Enable Control Line. The Read/Write tells the module whether to write data or read data from the register.

Serial LCD controllers typically have one Serial Data Line that writes data and cannot read. Normally, a Register Select Line(Sometimes designated A0) is used to tell the controller whether the incoming data is display information or a controller command

SPI, or Serial Peripheral Interface bus, is a synchronous (data is synchronized to the clock) serial data link standard that operates in full duplex mode, which means that devices that can communicate with one another simultaneously. To do this, two data lines are required. With this standard, devices communicate in a master/slave mode, where the master device (host processor) initiates the data and the clock. The LCD module is the (or one of the) peripheral slave device(s) attached to the data bus. Multiple peripherals (display modules and other devices) are addressed on the same serial data bus. However, the LCD module will only listen to the data it sees when the Chip Select line is active (usually low). If the Chip Select line is inactive (usually High), the LCD module listens to the data on the bus, but ignores it. The SDO line is not active when this state occurs. The SPI bus is comprised of four logic signals, two control lines and two data lines and is commonly referred to as SPI (4 wire).

With CS (Chip-Select) the corresponding peripheral device is selected by the LCD Controller. This pin is mostly active-low. In the unselected state the SDO lines are hi-impedance and therefore inactive. The clock line SCL is brought to the device whether it is selected or not. The clock serves as synchronization of the data communication.

The chip select signal CS is optional for a single device system, because you could tie the CS input at the LCD Module low, if the other lines are dedicated to SPI use. This is sometimes called a 3 Wire SPI Interface.

Since the SPI interface protocol is a de facto standard, many variations of the standard protocol are used. For instance, chip manufacturers may use some of the parallel data lines when configuring the IC driver chip for serial communication. chip manufacturers may use some of the parallel data lines when configuring the IC driver chip for serial communication.

I2C uses only two bi-directional lines, Serial Data Line (SDA) and Serial Clock (SCL), which are both typically pulled up with resistors. Typical voltages used are +5 V or +3.3 V. One of the strengths of the I2C interface is that a micro can control multiple devices with just the two I/O pins and software. Because of the I2C design, it is only half-duplex. The interface generally transmits 8-bit words, sending the most significant bit first.

LVDS (Low Voltage Differential Signaling) technology provides a port with low voltage difference and differential signals. Developed by NS Technology Co., the American company uses digital video signal to resolve the excess amount of resource consumed and reducing EMI (Electromagnetic Interference) while transferring high bit rate data using TTL (Transistor-Transistor Logic). LVDS ports are able to perform differential data transfer between PCB traces or balanced cables with a relatively low output voltage swing (350mV), allowing a transfer speed up to several hundred megabit per second with low voltage difference. As a result, low voltage swing and low current drive applications have led to dramatic reduction in resource consumption and noise.

Connector ports for devices such like cameras, displays, basebands, and RF interfaces are standardized under MIPI Alliance specifications. These specifications include design, manufacturing costs, structural complexity, power consumption and degree of EMI.

Hi, I"m trying to figure out how to connect this old TFT LCD from my old Toshiba satellite (that I ripped down all internal component to make a case for the rasp) to the Pi"s DSI interface. Could you help me?

The chip from the LVDS4PI EVO is EOL, so not an option anymore (and hard to find). I have some spare board available, also some interface cable which should match to your module.

Note: be sure to save the CCFL inverter! If that one - or the lamp itself - is death you can send your module to electronic waste scrap. Also save the interface cables to the inverter!!!

Gotta say, LVDS4PI looks like a huge improvement compared to those generic, bulky HDMI-to-LVDS that have so many unnecessary connectors for hooking them up to the Pi, such as VGA etc. LVDS4PI seems like a great module for compact projects, and being able to embed the circuits directly into new boards would make LCD panel-based projects even more streamlined!

LVDS4PI is using a DPI interface and converts it to LVDS. As the dual-channel transmitter uses on the EVO board is EOL and the inferface of my choice has always been DSI (as it leaves GPIO available to the user) they way to go for is MIPI2LVDS

What"s the compatibility like with your boards and all the LCD panels out there? I don"t have much experience with LCD panel tech, so I assume that the protocols for LVDS between panels can vary slightly (seeing how there"s thousands of manufacturers)...

If it"s a dead-dead situations : can I replace it with another generic inverter or not? (the factory inverter from my LCD is still intact ; see first post with Google Drive photos)

I had success with a ‘standard’ LVDS - HDMI bridge board but found I needed the brightness up full (controlled on the interface) to see the image properly. The brightness is not a function of the backlight but the pixel luminosity.

The beauty for me with the purchased board was that it came with that LCD interface cable - that alone was worth the cost, but I wish I had known about abugsworstnightmare’s board at the time.

A TFT, or Thin-Film Transistor, utilizes a display that allows for each pixel to be controlled by a transistor and separately address each position. The components of a TFT LCD module are a TFT LCD panel, one or more COG or COB driver ICs, a backlight, and an interface. An interface is a shared boundary across which two separate components of a computer system exchange information. As TFT displays have started being mass produced, production has improved, and the price has become more affordable.

There are now a number of TFT display interface technologies. The best interface to choose relies on particular end-product considerations. The last several years have seen the development of numerous TFT display interfaces, including LVDS (Low-Voltage Differential Signaling), parallel, SPI (Serial Peripheral Interface), and I2C or I2C (also known as I squared C) display, and others.

An SPI or Serial Peripheral Interface enables data exchange between two devices. Compared to parallel ones, it has the benefit of more intuitive and simple wiring. Since there is substantially less contact or crosstalk in the cable, SPI also allows for longer cables. The disadvantage of SPI is that it is slow and only allows for writing to the TFT LCD panel. SPI is typically used in smaller TFT LCD screens because of this. But perhaps your project might require a built-in LCD controller, for which an MCU Parallel interface might be a good fit.

An MCUPI or an MCU Parallel interface is usually pretty simple and usually requires display RAM. There are two common types that are found; the first is 6800, and the other is 8080. 8080 is nRD and nWR, 6800 is RD/nWR and E. A unique sort of parallel interface is the RGB interface. There is no need for display RAM. The MCU directly updates the TFT screen by delivering Red, Green, and Blue sub-pixel data (16/18/24 bits) and timing signals. The RGB interface offers a high-speed connection but requires more data cables and has more complicated controls.

A high-speed serial interface between a host CPU and a display module called MIPI Display Serial Interface allows for the integration of displays to provide high performance, low power, and low electromagnetic interference (EMI) while also lowering the number of pins and retaining vendor compatibility. Designers can use MIPI DSI to provide transmission of stereoscopic content and to enable excellent color rendering for the most demanding picture and video situations.

Low-voltage differential signaling, or LVDS, is a high-speed, long-distance digital interface that transmits serial data (one bit at a time) through two copper wires that are 180 degrees apart from one another. This setup makes the noise easier to identify and filter, which lowers noise emissions. Focus LCDs offers a versatile display that uses this technology, E70RA-HW520-C. The monitor in question is a 7.0" TFT with 1024x600 pixels and a maximum color depth of 16.7M. The inbuilt gate and source driver ICs in this display can be programmed using a typical graphics controller.

HDMI is one that many consumers may already be familiar with. High Definition Media Interface provides a connector and cable definition that supports high-bandwidth video and audio streams. HDMI is an almost direct replacement for analog video standards.

There are then a diverse set of interfaces that can be considered for your display project; whether you decide to go with HDMI, LVDS, MIPI DSI, or the others mentioned, or simply can"t decide, feel free to contact Focus LCDs, where we can address use-case specific questions and provide additional details.
