Dot Matrix is an unique category of LED Displays and also found in LCD and OLED products. The concept of LED Dot Matrix Display is the same as LCD Dot Matrix and OLED Dot Matrix. It is able to show characters, numbers or graphics by light up different pixels(dots) of a Display.
Most LEDs in a Dot Matrix Display have a shared anode(co-anode) or cathod(co-cathod) pin, and controlled by a driver IC.
Normally, this driver IC is seperatelly from LED Dot Matrix and provided from the customer. Although the driver IC commonly from customer’s choice, the IC could sit on cutomser’s PCB board or LED Dot Matrix Display Module. This all up to customer’s requirement.
LED Dot Matrix Display is highly application/customer driven products. Besides shap and pixels, the color(s) of each pixels are also widely diverse across different displays.
In another term, the color(s) of each pixel are independent to another pixel. Although, rectangle is the most common shape for Dot Matrix Display, but other shapes such as circle or/and triangle are also available for various usages.
Not only the shape of Dot Matrix LED Display could be different, but also the shape of each single dot could be different. Circle or square are the most common shape of each dots, but rectangle also able to be found in certain application. In rare case, triangle, oval or other shapes are also used.
The Global Dot matrix LED display market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
MAX7219 LED Dot Matrix 4 In 1 Display with 5P Line Module The MAX7219 Dot Led Matrix Module is a serial input common-cathode driver that interfaces micro-controllers to LED matrices. All common micro-controllers can be connected to this module by using a 4-wire serial interface.
Each output can be addressed without refreshing the entire display. This module requires only 3 I/O lines for driving the display, making it ideal for your microcontroller projects. Only one external register is used to set the segment current of each LED.
This product has 4 Dot Matrix LED’s cascaded to form a single LED Display to allot more area to the user on the display. This is Dot Led Matrix Module incorporating MAX7219 Driver chip.
By using this dot LED module in the upcoming project, the users will be able to add some great cool animation.Connecting the two modules is also very easy. Only connect the output pins of the previous breakout board to the input pins of the new module, thus with such arrangement.
