SK-GEN4-28D is a monochrome graphic LCD module available in STN and FSTN LCD technology with a resolution of 128 x 64 pixels and a diagonal size of 28.95 mm (1.14"). It offers a passive display matrix with LED backlighting and utilizes 18-bit 8-level gray scale. These features make it suitable for a wide range of applications such as automotive, medical, consumer electronics, and industrial.

The SK-GEN4-28D LCD module is designed with a built-in controller, a powerful processor, memory, timing, and input voltage regulation. It is built with a sturdy metal case and has a user-friendly interface for controlling the LCD. This allows for easy integration into any system. Besides the backlighting feature, the module also includes a 25mA automotive backlight, which offers brighter illumination than traditional LCDs.

To understand the working principle of the SK-GEN4-28D LCD module, it is important to first gain an understanding of how LCDs work. A liquid crystal display (LCD) consists of two sheets of polarizing material with a layer of liquid crystal between them. When an electric field is applied, the molecules in the liquid crystal align themselves in the direction of the field and create a microscopic pattern on the LCD. This pattern then modifies the direction of light passing through the layers, forming a visible image on the display.

The SK-GEN4-28D utilizes a passive matrix display that utilizes a thin film transistor (TFT) to control each pixel. It works by activating the gate line and data line while powering the TFT to activate a specific row and column of the matrix. When an individual pixel is activated, the associated TFT switches on and transmits power to the liquid crystal cell associated with it, resulting in a change of light passing through the LCD, creating a visible image on the display.

In addition to the backlighting option, the module is equipped with an LED temperature sensing feature that prevents the module from overheating. This feature is beneficial in longer display modules, since it prevents the display from appearing faint in time due to overheating. It also improves the brightness of the image by enhancing the power efficiency.

The SK-GEN4-28D is a versatile graphic LCD module suitable for a range of applications. Its monochrome display and 8-level grayscale resolutions make it perfect for displaying images and text in a variety of different environments. Furthermore, its power efficiency and temperature sensing feature make it well suited for use in a wide range of industries.
