LED Display Module

Bolymin - LED Display Module 

LED Display Module   

A LED display Module is a flat panel display that uses an array of light-emitting diodes as pixels for a video display.

LED displays are brighter and visible from a greater distance, which makes them optimum for sunlight readable application. Also, it offers a wider viewing angle up-to 178 Degree (Horizontal & Vertical).

One major challenge to drive the LED display is higher numbers of MCU (Microcontroller) I/O pins requirement, which makes it difficult to use it with MCU that have lower number of pins such as PIC12F.   

Seven Segment LED Driving Method

Bolymin LED Display Module   

Bolymin LED Display Module consists of LED Display, PCB, IC and it is connected through the SPI interface. 

For example, for example with old method 48 I/O could reduce to 4 I/O based on Bolymin design and provides full control of all digits and decimal points.

Bolymin – LED Display Module

LEDs are flat panel displays that emit visible light when an electric current passes through the light-emitting diodes. Bolymin LED Display Module consists of LED Display, PCB, IC and it is connected through the SPI interface. Compared to LCD displays LED displays are brighter, have a wider viewing angle and visible from a greater distance. However, the downside is they are resource-hungry.
