The LTP-1557AKA Display Modules - LED Dot Matrix and Cluster are consisting of ultra-bright LEDs which are mounted on a PCB containing a latch circuit. It is created to easily assemble into a 16×7 dot matrix display for monitoring information for details.

This display module can be used for a variety of applications, such as test equipment and data processing display. It is also suitable for displaying clocks, electric meters, small size LED displays, process controllers, and digital calculators.

The display module consists of two parts: an LED cluster module and a control circuit. The cluster module is composed of 162 ultra-bright LEDs (9 red, 63 green, 60 blue, 12 orange, and 8 white) that are arranged in a 16×7 dot matrix. The control circuit consists of two types of circuits: logic and latch. The logic circuit is used to control the light intensity and the latch circuit is used to store the dot matrix data that is sent from the MCU.

The LTP-1557AKA works with two data buses: a “Y” bus to transmit the data to the latch circuit and the “X” bus to control the light emission. The logic circuit is used to translate the binary data and control the light emission. The latch circuit (or shift register) stores the data sent from the MCU and controls the relevant output port. The data is sent from the MCU in serial from, which is then converted to parallel data and then sent to the LEDs. Depending on the signal received, the LEDs will emit light accordingly.

The LTP-1557AKA is designed for durability and can be used for applications in outdoor, harsh environments, such as automotive and industrial environments. Its wide operating temperature range (-40ºC to +80ºC) enables the module to withstand extreme temperatures. The ultra-bright LEDs have a wide viewing angle of 160º, making it ideal for applications that require visibility from all angles.

The LTP-1557AKA module is powered by two power sources: one power source is used to operate the LEDs while the other is used to operate the logic circuit. The LED power source runs at 1.2 V to 3 V and the logic circuit power source runs at 3 V to 5 V, depending on the application. Since the LED unit operates at a low voltage, there is no need for complex heat dissipation mechanisms.

In conclusion, the LTP-1557AKA Display Modules - LED Dot Matrix and Cluster is the perfect choice for applications that require an ultra-bright LED display. With its wide viewing angle and operating temperature range, it is suitable for applications in a variety of environments, including outdoors and extreme temperatures. It is easy to use and comes with two power sources, making it a reliable and efficient display module.
