LDQ-C513RI is a popular display module that is used for LCD character and numeric displays. It has a variety of features, making it suitable for many different types of applications. In this article, the application field and working principle of this display module will be discussed.

The LDQ-C513RI has a 5x13 dot matrix LCD and a 5 row x 22 column LCD. It is a character display that is capable of displaying up to 6 lines of information with 40 characters per line. The keys are made of a quartz-based substrate and each character has two LED illuminated states. With its low power consumption, it is ideal for any type of display applications.

The LDQ-C513RI display module comes with a variety of features, such as contrast control, automatic contrast balance, positive contrast, wide character angle, display cleaning, text rollover, and pulse width modulation (PWM). These features make the display module suitable for a wide range of applications. It is also compatible with software, such as LabView, for easy integration with other components.

The working principle of the LDQ-C513RI display module is based on the principle of how LEDs emit light when excited. The module uses three individual LEDs per character, which are positioned in a column in front of the LCD panel. The LEDs on the left and right sides of the column are connected to the left and right rails of the module, respectively. When the module receives an electrical signal, the LEDs emit light in the shape of the desired character.

The LEDs are connected to the module through two different voltages. One is the logic 0 voltage, which is the low threshold voltage, while the other is the logic 1 voltage, which is the high threshold voltage. Depending on the voltage level, the brightness and contrast of the display can be adjusted. The contrast of the display is controlled by controlling the intensity of the current, while the brightness is controlled by changing the full-scale current.

The LDQ-C513RI is a versatile display module that is designed for a variety of different applications. It can be used in industrial, automotive, medical and consumer electronics applications. It is suitable for digital signage, point-of-sale (POS) systems and displays, automotive instrumentation and digital dashboards. It is also used in factory and process automation, marine applications, data loggers and medical equipment.

The LDQ-C513RI display module is a popular choice for many applications due to its wide range of features, low power consumption and compatibility with various software programs. With its high contrast, wide angle viewing and high resolution, the LDQ-C513RI is an excellent choice for any type of display application.
