Display Modules - LCD, OLED Character and Numeric

BLC2021-AL-USB-FG is a lightweight display module, which is mainly used for display of characters and numbers in portable applications, such as mobiles, laptops, cameras and tablets. It is composed of a display unit, a driver IC and an interface. The driver IC is used to control the display content, while a range of interfaces are provided for connection to the host device.

The display unit consists of a variety of light emitting diodes (LEDs) and a range of LCD, OLED character or numeric display elements. The LEDs are used to provide general illumination, while the character and numeric display elements are used to present numerical and textual data. Depending on the type of display selected, different types of elements are used to create different visual effects.

The driver IC is responsible for controlling the various elements of the display. It can be connected to the host device through a variety of interfaces, such as USB, I2C and SPI. The driver can be programmed to display different types of data or messages, as well as providing animated or static screen effects.

Central to the BLC2021-AL-USB-FG’s working principle is its ability to control the brightness of each individual element within the display. Each element is connected to a driver IC which is separately controlled via external programming, such as a PC. The driver IC can adjust the individual brightness levels of each element to create a desired level of overall brightness. This light level is then maintained by the module’s internal memory, meaning that the same level of brightness can be maintained regardless of the level of displayed data or images. This means that, for example, the display of a text message or image will not dim as the user scrolls, allowing for a high level of brightness for longer periods of time.

The BLC2021-AL-USB-FG’s wide range of support for different displays makes it an ideal module for a range of applications. Its compact size and lightweight design make it ideal for portable applications, while its flexible programming interface and adjustable brightness levels make it suitable for a variety of uses. It is therefore suitable for a wide range of applications, such as automotive displays, medical equipment and industrial applications.
