LED character and arithmetic displays are widely used in today’s electronic products for information display and control. Among them, the LED Character and Numeric display family, represented by the SA40-18CGKWA, is particularly well-suited for character and arithmetic display applications. This article will introduce the application field and working principle of the SA40-18CGKWA.

The SA40-18CGKWA is an ultra-bright 14-segment two-digit numeric display in an SMT package. It can be used to display numeric information and has been applied to the following fields: industrial digital identification systems, voltmeter, ammeter, frequency counters, digital clocks, digital thermometers, and digital humidity meters. The SA40-18CGKWA display module is composed of a circuit board, display window, LED device and a control signal driver chip.

The working principle of SA40-18CGKWA is as follows. The control signal is first sent to the signal driver chip. The signal driver chip decodes the control signal and drives the anode and cathode of the internal LED. The input information is displayed on the common anode pattern surface. The display uses ultra-bright commonly anode single LEDs, which provide bright optical output. The technical parameters of SA40-18CGKWA can meet the demands of various applications.

In conclusion, the SA40-18CGKWA is an ultra-bright 14-segment two-digit numeric display in an SMT package. It is suitable for character and arithmetic display applications in industrial digital identification systems, voltmeters, ammeters, frequency counters, digital clocks, digital thermometers, and digital humidity meters. Its working principle is that the control signal is first sent to the signal driver chip and the input information is displayed on the common anode pattern surface. It is an ideal LED character and numeric display.
