Product Specifications
--Product Description
Congratulations to okystar for becoming a strong customer of Alibaba
Specification: 1. Display type: 7-Segment (x 4) 2. Type: Common Cathode (CC) 3. Maximum Ratings: IF: Maximum Forward Current 20mA (constant current per segment) VF: Maximum Forward Voltage 2V (Typical) 4. Character Height: 14.2mm (0.56″) 5. Module (L x W x H):51 x 19 x 8mm (2 x 0.75 x 0.31) 6. Weight: 8g Features: 1. 4-digit 7-Segment display with common cathode (CC) 2. 0.56″ high characters 3. 20 mA current 4. 2V forward voltage drop Theory of Operation 1. Each digit of these displays have 7 separate LEDs comprising the 7 segments of the digit plus an 8th LED that functions as a decimal point. The LEDs are labeled segment A thru G and the decimal point is DP. 2. The displays are common cathode (CC) type which means that all 8 of the LEDs in each of the 4 digits have their cathodes tied together and these are pulled to ground to enable that digit. These connections are labeled G1 – G4 in the drawing. 3. To light a particular segment, the control (anode) pin for that segment is driven HIGH. These 8 control pins should each have series current limiting resistors to prevent damage to the LED module or the UC. Instead of the control pins, current limiting resistors can be put on the pins connected to ground so that fewer are needed, but in that case the brightness of the display will vary depending on how many segments are lit at one time so that practice is not really recommended. 4. The connections for each of the individual segments such a ‘A’ are connected together in all 4 digits, so the displays are designed to be used in a multiplexed fashion unless you want all 4 digits to always show the same number or character which generally isn’t all that useful. | ||||||
