Display Modules

LED Dot Matrix and Cluster

The LTP-757KA is a variant of LED dot matrix and clusters, which can be used in various digital display applications. It is a common anode type, with 7 columns and 57 rows and a total of 399 LEDs. Each individual LED can be activated, making it possible to achieve a wide range of digital functions, such as displaying the time, date, temperature, message and many other types of digital information.

Application Field

The LTP-757KA is designed to be used in digital display applications, such as clocks, thermometers, message boards and many other products where digital information needs to be displayed. It is also used in many industrial and commercial products, such as ATM\'s and vending machines.

Working Principle

The working principle of the LTP-757KA is based on the idea of multiplexing the LEDs in order to achieve greater brightness. The individual LEDs are connected in a row-column matrix and are activated by applying a current through the appropriate row and column connections. When the LED is activated, the current travels through the LED, causing it to light up. The current is then routed to the next LED in the matrix, and so on, until all of the LEDs have been lit. Multiplexing is used to ensure that each LED is lit for the same length of time, thereby ensuring a uniform and bright display.

By controlling the flow of current through the LED matrix, different output signals can be generated, allowing for a wide range of digital displays. For example, a clock can be created by setting each LED to correspond to one of the 12 hours in the day, and the LED will light up the appropriate time. By varying the pattern and timing of the LEDs being lit, more complex digital displays can be achieved.

In addition to using the LTP-757KA in digital displays, it can also be used in other applications, such as security systems, lighting systems and gaming applications. The LTP-757KA is a versatile and reliable LED matrix and cluster that can be used for a wide variety of applications. It is ideal for projects where a high level of brightness and uniformity is required, and its multiplexing capabilities allow for a wide range of digital displays.
