Working Principle

The QBQ28O1 display module uses a segmented LED display. It consists of two parts: a light source and a character pattern. The light source emits light onto the character pattern. This is called the projected display. The character pattern is made up of two types: the anode and the cathode. The anode consists of small LEDs arranged in a grid, while the cathode consists of a single high brightness LED. When current is applied to the display, the LED character pattern is lit up.

The LED character pattern is controlled by the driver chip. The driver chip contains a set of control signals that control the brightness of the LED. The driver chip also contains a set of circuits that control the blink rate of the LED. The blink rate can be adjusted to change the contrast of the display.

The QBQ28O1 is also capable of displaying icons. The icons are generated by the driver chip, and they are displayed on the character pattern. These icons can be used to show information such as time, numbers and the status of connected devices.
