tft display with serial interface brands

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.

The PICASO-GFX2 belongs to a family of processors powered by a highly optimised soft core virtual engine, E.V.E. (Extensible Virtual Engine). EVE is a proprietary, high performance virtual processor with an extensive byte-code instruction set optimised to execute compiled 4DGL programs. 4DGL (4D Graphics Language) was specifically developed from ground up for the EVE engine core. It is a high level language which is easy to learn and simple to understand yet powerful enough to tackle many embedded graphics applications.

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.

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.

This 2.2-inch LCD module with a resolution of 240X320. It only requires 5 IOs to lighten the display, or a direct hardware serial peripheral interface that can be driven. LCD color screen display has SMT reflow and industrial control quality, which can work stably for a long time.

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).

Occasionally, SDI (serial data in) may be called out as MOSI (Master Out Slave In) from Motorola"s original name for these lines and MISO (Master In Slave Out) for SDO. The chip select line may be alternatively labeled SS (Slave-Select), or STE (Slave Transmit Enable). SPI is sometimes referred to as National Semiconductor"s trademark Microwire, which is essentially a predecessor of SPI, which only supports half duplex.

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.

SPI Data transmissions usually involve two shift registers. Most display module applications normally use 8-bit words. However, different size words, such as 12 bit, are also used. By convention, the most significant bit is shifted out of one shift register while the least significant bit is shifted in. The word is then written into memory if the CS (chip-select) is low (active). If not, the data is ignored.

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.
