Display modules are widely used in many kinds of electronic products, such as computers, televisions and smartphones, for the purpose of displaying information like images, text or video. Among them, LCD, OLED, and Graphic display modules are the three main categories. Among these, LCD displays are the most common, and even now, LCD display technology is developing in various directions, from passive to active module applications. 2700770 is one of the most used active display modules for applications like industrial control systems, prototype development, and automotive displays. The major features and working principles of 2700770 will be discussed below.

Features of 2700770
2700770 is a 4-wire active display module with an integrated driver IC. The major features include:

  • A normal-white LCD panel with a resolution of 128 x 64.
  • Integrated controller with a user friendly parallel bus interface.
  • On board power supply, self-refresh, and supply voltage auto detection.
  • On board contrast adjust, CE mark, and font expanding function.
  • Industrial grade wide temperature range (from -20°C up to +70°C).

The features mentioned above are obviously beneficial for various applications, like industrial control systems, prototype applications, and display interactions with the user in cars, for example.

Working Principle of 2700770
2700770 is a type of LCD (Liquid Crystal Display) module. It works on the principle of a light valve. A liquid crystal material is sandwiched between two conductive plates, one of which having transparent electrodes in the form of stripes. By applying a voltage to the electrodes, an electric current is induced which can control the orientation of the molecules of the liquid crystal material. This property is used to alter the light passing through them, thus providing the basis of a light valve. Thus, when a voltage is applied across the electrodes, the molecules will align with each other and cause light to be blocked, thus forming a picture.

2700770 operates with a 4-bit parallel interface and it offers several advantages over other LCD modules like a wide viewing angle and Contrast Ratio, High Brightness, Colorful and excellent Transmittance, and Interface Flexibility. The contrast ratio of the LCD panel can be adjusted by an integrated controller for clearer display. Moreover, the integrated image data buffer avoids any data loss during a refresh cycle.

Conclusion
Overall, 2700770 is a 4-wire active display module which offers a wide range of features, including an integrated driver IC, self-refresh and supply voltage auto detection, contrast adjust, CE mark, and font expanding function. It has been widely used in various applications like industrial control systems, prototype development, and automotive displays. Its working principle is based on the light valve technology which involves controlling the orientation of liquid crystal molecules to block the passage of light and form a picture.
