The LOD-H02004DP-G is a type of LCD module that includes both character and numeric displays. It consists of two 16x2 character screens that are each capable of displaying up to 32 characters. It also includes two 8x1 numerical displays. This type of module is typically used in industrial control, instrumentation and medical applications.

The working principle of the LOD-H02004DP-G is fairly simple. It employs a series of LEDs placed behind the LCD and matrixed with the display to provide a readable image. The LEDs are connected to two voltage sources, one providing the power to turn on or off the display and the other controlling the brightness. The LEDs are then put under the control of a single controller, typically an IC, which drives them in a sequential fashion to form a visual image.

In order to display a character or numeric figure, the LOD-H02004DP-G LCD module uses the combination of a 4-bit BCD code, which stands for binary-coded decimal and 5-bit grayscale codes. These codes are translated by a keyboard matrix circuit that is present on the module to actual figures displayed on the screen.

The LOD-H02004DP-G is a good choice for applications that require an easily readable graphical display such as instrumentation, medical and industrial control systems. Its combination of two character screens and two 8x1 numerical displays gives it the versatility to suit many different kinds of applications. Its simple working principle also makes it easy to use and operate.
