SC03-12EWA Application Field and Working Principle

The SC03-12EWA display module belongs to the Display Modules - LED Character and Numeric category of electronic components. It is a 4-digit 7-segment common anode display module that is highly efficient and reliable in operation. The SC03-12EWA can be used in various applications and disciplines like scoreboards, timekeeping, industrial automation, production systems, and so on.

In terms of structure, the SC03-12EWA is composed of 45 pieces of LEDs and a PCB plate. The LEDs are individually packaged in SMT (surface mounted technology) packages. The light source of each LED is a die with an inorganic electro-luminescent material. The PCB plate is made with high-quality material, aiding in delivering electricity and a solid electronic connection between the board, LED and other components.

The SC03-12EWA is operated through a voltage supply of 7.2V-7.8V DC. The module acts as a 4-digit common anode 7-segment display character. Each segment can be individually activated, allowing for a clear display of numerical characters and symbols. The SC03-12EWA is also dimmable, meaning that the brightness of the display can be adjusted through pulse width modulation (PWM) of the voltage. This feature allows for the display to be used under different light environments.

In order to adapt the SC03-12EWA to a particular application, various controller boards, drivers or different interfaces can be used. For example, SPI bus or I2C bus. Depending on the controller board, specific signals will be used to activate the various segments of the display. A sequence of instructions written in a specific language will determine the display pattern.

For optimal performance, the SC03-12EWA should be mounted in a correct orientation and observation angle, after which the display should be connected to a power source and the specific controller board. When the circuit is connected, using the controller board, low voltage signals will be sent in order to correctly display the intended character or symbol.

In terms of features and performance, the SC03-12EWA is an excellent choice for applications requiring precise numeric displays. Its ability to dim the display, using a PWM signal, makes it especially attractive for light environments. Its size and weight are also favourable for embedded system applications. In general, the SC03-12EWA is an effective and reliable display module for a wide range of applications.
