LAP-301YL is a type of LED character and numeric display module, including a variety of LED display area configurations, such as 8×8 matrix and 7-segment numeric display. It is regularly used in predetermined applications, such as calculating machinery, appliances, telecommunication equipment, as well as traffic and medical systems.

These modules come equipped with four frequency channels, which provide the ability to display various characters and numbers. The display layout is optimized to ensure that a wide range of text and graphics can be viewed clearly on the small LCD of a cell phone or notebook PC.

Within the module, an extra shift register is installed for operating the LED displays. Generally, it is equipped with an 8-bit serial data control selector to select the LED. Moreover, the module itself is driven by the LM329 LED driver.

In terms of display configuration, LAP-301YL mainly provides an 8×8 LED matrix and 7-segment display. Both are capable of displaying up to eight characters or numbers; they also feature up to seven dots which can be used to form any kind of characters or numbers.

The operational principle of the LAP-301YL module is relatively simple. First, when the power is switched on, the electricity will flow through the C1 and R1 resistor to feed the ICM7LT and IVLM329 ICs with the necessary power.

The ICM7LT IC is responsible for collecting data from the serial data port and decoding the data into 8-bit parallel data format. This data is used to control the MCU to drive the LED characters.

The IVLM329 IC acts as a driving circuit for the LED display. In this case, the common anode of the LED is connected to the power line and the segments of the LED are connected to the corresponding output pins of the IC.

This module is also equipped with one control pin for programming the display. The pin should be connected to low level for programming the display. Once programmed, the display will cycle through the stored characters or numbers.

Overall, the LAP-301YL is a reliable, high-quality LED module designed and manufactured to meet the most demanding requirements in the display market. With its user-friendly interface, the module can be used in a wide range of applications, from calculating machinery to telecommunication equipment.
