LED displays are widely used in many industrial applications, including traffic control, office automation, safety, environmental monitoring and machine control. Among them, the QBSS400R display module is the most powerful, most versatile and cost-effective of all LED display modules available today. It can easily be used to create customized display solutions for applications such as graphic and text display.

QBSS400R is a high-density LED character and numeric display module with a total of 400 dots for graphical and text display. It has a wide viewing angle and excellent contrast, high brightness, long life and low power consumption.

The QBSS400R consists of five 7-Segment LED characters, four characters across and five characters up, and two 16-bar LED Bar Displays, one side and one across. It also has two LED indicators, one RGB and one monochrome, and one LED power indicator. There are 11 SMD LED Blocks, six 4-digit blocks, two 2-digit blocks, two 1-digit blocks and one 0-digit block. All components are totally certificated according to UL, ROHS and IEC standards.

The QBSS400R display module supports 256 different display modes. In addition to Standard display content such as numerical, text or graphic, its 256 different display modes provide extended capabilities such as dimming level, color selection, blink sequence and many other functions. Further, its LED power indicator provides information about the system status such as an alarm or a warning.

The QBSS400R is designed to easily integrate into existing applications and products, providing an enhanced visual experience. For instance, it can be used as a backlight for LCD displays, helping to easily display texts and graphics in customized solutions. Its extended temperature range and superior brightness make it ideal for outdoor applications.

The working principle of the QBSS400R is based on direct current drive. An increase in the voltage applied to the cathode will cause a corresponding turn-on of the seven LEDs within the display. Conversely, a decrease in the voltage at the cathode will cause the display to turn off. The supply voltage range is generally +3.3 V to +7.0 V and a temperature range of -40°C to +85°C.

The QBSS400R is an ideal choice for applications requiring a high-density LED display module. It provides a cost-effective and reliable solution for any application that requires a graphic and text display. Its extensive features, combined with its superior performance, make it the perfect choice for any application.
