QBSS390CR Optoelectronics

The QBSS390CR is one of the most versatile LED character and numeric displays. Its working principle is based on the use of External Light Emitting Diodes (ELEDs) to illuminate a variety of character and numeric formats. This device can be used in a wide range of applications and is one of the most flexible device available in the market.

The display module uses two types of ELEDs; which are arranged in an array. The topmost ELEDs illuminate the character and numeric fields, while the bottom ELEDs provide backlight to improve readability. The form factor of the device is small and compact, allowing it to be used in a variety of applications such as LED character displays for multimedia personal computer, desktop calculators, electronic data processing systems, embedded system automation, security systems, industrial scheduling and process control.

The device works by utilizing two-wire serial communication interface and a host processor. The host processor will send data to the QBSS390CR, which will then be interpreted into relevant instructions. The instructions are then converted into the corresponding character and numeric display patterns. The patterns can be updated in real time, as the display is continuously being driven by the host processor.

The ELEDs in the device are powered by a series of LED drivers, which can be pre-programmed to support various types of character encodings. The LED drivers are also responsible for providing the necessary power and control signals to the ELEDs. These power signals can be adjusted to produce different levels of brightness, which allows the user to customize the display to their desired level.

The QBSS390CR is highly versatile and is able to display a wide range of text and numeric formats, such as hexadecimal, decimal, and binary. This device is capable of supporting up to 24 characters, allowing for a range of different applications. Additionally, this device has the capability to accept a variety of input formats, such as ASCII, BCD, and hexadecimal. Furthermore, it is also capable of driving up to 8 ELEDs simultaneously and can display up to 4 characters at any one time.

In conclusion, QBSS390CR is a highly efficient, robust and flexible LED character and numeric display device that is suited for a variety of applications, including multimedia personal computers, entertainment systems, embedded system automation and industrial scheduling. Its two-wire serial communication interface and programmable LED drivers allow for easy integration into a wide range of systems.
