LCD Numeric Display Modules
LCD Numeric Display Modules are small, self-contained LCDs that are designed to display only numeric values (usually 3-7 digits). They are typically used in electronic systems to display readings such as temperatures, time, or current flow. This type of LCD operates in either transistor-transistor logic (TTL) or in complementary metal-oxide semi-conductor (CMOS). The TFT and LCD backlight that is used for these modules come in a variety of color choices and backlight options. The LCD module is composed of two main parts: the LCD display and the display hardware. The hardware usually includes a driver, a controller, and display electronics. The driver controls how the display images are transferred to the LCD. The controller handles communications between the LCD and the display system, while the electronic components allow the LCD to display different images. This type of LCD display is traditionally available in single character heights from 0.5 to 4.3 mm, with a range of resolutions from128 to 1024 dots. For improved performance in daylight operation, LCD modules with a polarized film can be used.
