LTM-8328PKR-04 Application Field and Working Principle

LTM-8328PKR-04, which belongs to the group of display modules-LED character and Numeric, is a multifunction display module that is widely used in industrial control systems, medical devices, etc. An advantage of this module is that it can drive both segment display and dot-matrix characters. It is featured by a high contrast ratio and wide viewing angle that makes the information whether in segment display or dot-matrix mode clearly visible by users. The module is powered by operating voltage of 5V and maximum power of 0.4w, which is not too high to consume a significant amount of energy.

The basic display components of this module include dot-matrix and segment characters. A dot-matrix character is made up of 8x8 LED. As this matrix is driven between multiplex, it is capable of displaying 8 digits at the same time. The segment characters is made up of 8 segments (including dot/decimal point) and 7 common sources. With the support of segment controller ST7056i, each character can be composed of up to 28segments. Apart from single segment displays, the module can also drive multiple segment displays like those of alphanumeric characters with 8x14, 10x16 and 12x16 formats.

The working principle of LTM-8328PKR-04 mostly depends on the driving technique from ST7028i. This is a compact controller that combines LCD (liquid crystal display) driving, segment driver and display RAM in one package. The controller makes it possible to form characters in segment, dot-matrix, and alphanumeric display. The microcontroller can also control 32 character segments and 64 array displays. To make the module work properly, it needs to be partnered with a power driving module.

Despite the small size of LTM-8328PKR-04, the module provides users with unprecedented flexibility in terms of the control of segment display or dot-matrix operations. It can be regarded as a one-stop solution for various displaying needs in industrial control systems, medical devices, and other fields. Furthermore, such flexibility can be achieved without too high power consumption.
