APA107, HD107S, and HD108 all belong to the CLK+DAT control type. Typically, we think of APA107 as an alternative to APA102C and SK9822, HD107S as an upgrade to APA107 and APA102, and HD108 as an upgrade to HD107S. Among all the addressable led strip IC chips, only HD108 supports 16-bit 65536 grayscale variations at present, the others are 8-bit 256 levels of grayscale.
HD108 LED has the fastest refresh rate, responds and updates LED status instantly, and with a 16-bit 65536 high-definition grayscale and a wider range of colors to provide richer, more realistic and detailed images and animated lighting effects. With optimal color matching and consistency across the entire HD108 LED strip or pixel matrix, and low forward voltage drop, HD108 strip is ideal for LED screens requiring the best animation and visual effects.
What is the difference between APA107, HD107s, HD108, APA102, and SK9822 led strips?
• SK9822: 4.7 kHz PWM, transmission rate 15MHZ. • APA102: 20+ kHz PWM, transmission rate 20MHZ.
• APA107 is a 4-pin programmable LED IC chip inside an RGB or White SMD5050, 9 kHz PWM frequency, transmission rate 30MHZ.
• HD107s is a 6-pin LED IC embedded in RGB/White SMD5050 or RGB SMD2020/ SMD3535, 26+ kHz PWM frequency, transmission rate 40MHZ.
• HD108 is a 6-pin LED IC built-in RGB SMD5050, PWM frequency is up to 27 kHz, 40 MHZ data rate.
