Our 64128LX monochrome graphic LCD module has a viewing area of approximately 60 x 30 mm. This LCD is suitable for a wide variety of applications and is available with several different backlight colors. The COG IC is the Sitronix ST7565R. This LCD has a FPCinterface.

The ST7565R is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or 4-line SPI display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor. Because the chips in the ST7565R contain 65x132 bits of display data RAM and there is a 1-to-1 correspondence between the LCD panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The ST7565R chips contain 65 common output circuits and 132 segment output circuits, so that a single chip can drive a 65x132 dot display (capable of displaying 8 columns x 4 rows of a 16x16 dot kanji font).

The liquid crystal display (LCD) technology has been used in several electronic products over the years. There are more reasons for LCDs to be more endearing than CRTs.

Have you ever asked yourself what LCD is? No worries, we are here for you. Therefore, like in any display gadget, liquid crystal display coordinates with a microprocessor or microcontroller. The MCPU and MCU send the brightness that every pixel should produce. It creates the required color of the pixel for your LCD screen.

However, the mode of communication between the MPU/MCU and an LCD segment is known as the interface. We shall discuss more of the LCD interface in this guide.

The LCD interface is a link between the flat panel display module and the multimedia processor. Therefore, the interface can be separated or incorporated as part of the structure on the chip. Additionally, the application produces an image, and then the screen displays it using an LCD interface for the user.

Besides,  the serial peripheral interface has another component known as the slave select (SS) or chip select. The function of the SS is to wake the peripheral to receive or send data. For instance, since the SPI can support several peripherals, the SS can wake particular peripherals instead of all. Finally, you can use the SPI in graphic, character, digit, and small TFT LCDs. It allows simple interfacing, affordable hardware, and faster speeds than in the SCI.

It is another serial interface in LCDs that resembles the SPI with slave, clock functions, and master. The I²C does not integrate the SS line as in SPI. Therefore, a process known as addressing is essential in selecting a slave to communicate. A frame of the signal is sent on the data bus to address a specific slave after the first bit. Nevertheless, the output signal gets to every slave connected with, although only the slave with the corresponding address to the signal will receive the message.

The MCU interface is essential because it can write and read data stored in the internal frame bugger or the gadget"s storage. Therefore, if you want to store images for future use, MCU is the best match for you.

Additionally, in MCU parallel interface for Liquid Crystal Displays, data signals are sent through data lanes on either 18-bit, 16-bit, 9-bit, or 8-bit data channels. Besides, the MCU interface is simple, although it requires a display RAM for its memory functionality. Also, you can use it in graphic LCDs, character LCDs, and small TFT LCDs.

LVDS is an acronym for Low-Voltage Differential Signaling. This type of interface is essential as a complement for large LCDs and peripherals that require high bandwidth, such as HD graphics and fast frame rates. Therefore, it is a good choice due to its fast data transmission while consuming low voltage. One of the LVDS interface wires carries the precise inverse of its companion. Additionally, the electric charge from one wire is correctly masked by the other wire, reducing the interference to the wireless system nearby. Finally, at the recipient end, a circuit checks the variation in voltage between the two wires.

Red Green and Blue (RGB) interface functions are to link with color displays. It transmits 8 bits of data for each of the colors in every clock oscillation. Therefore, this means there are 24 bits of data sent for every clock oscillation.

Currently, you must have seen an improvement in terms of performance as electronic devices become smaller and easy to use. Therefore, this has led to the introduction of an embedded display port. The interface connects a video device to a display device and carries USB, audio, and other data forms. Moreover, this display port offers a high-performance external A/V interface hence high display resolutions of 4K. Additionally, the motive behind the development of this interface is due to several computing requirements. First of all, the main requirement is hardware integration.

This is a new technology development from the MIPI alliance. Mobile Industry Processor Interface has become a preferred option for mobile developers. This interface uses the same signaling as in LVDS. It uses a clock pair and 1-8 data lanes. Mobile Industry Processor Interface supports complex rules that allow low power and high-speed modes. Additionally, it reads data coming from the display at low rates.

When choosing the correct display interface for your device, you need to consider several factors. Therefore, it requires you to know how to connect the display to your electronic system. Nevertheless, it would be best if you choose the correct interface for your display. Additionally, consider the amount of data transferred and the refresh rate your system requires.

Finally, we have made it easier as we have given you all the details on each display interface, including the pros and cons. Therefore, having gone through our guide, you will never have issues when making your choice.
