TLC6948: RGB LED Matrix (Display) Driver Inquiry

Minsu Park

Part Number: TLC6948

Tool/software:

Hi, TI expert

I would like to inquire about RGB LED matrix solutions.

- Specification

1. RGB LED

2. Up to 2048 LEDs(64x32)

3. Each LED current is 20mA

4. Frame up to 60Hz

I would like to ask if there is a reference circuit diagram and sample code for the TLC6948 solution.

I would like to ask if there is a better solution other than the TLC6948.

Best Regard

Hi Minsu,

I just want to check the spec:

1. does 64*32 mean the RGB pixel number?

if the average current is up to 20mA, i will suggest use LP5892 or TLC69628.

LP5892 is 48 channels,40mA, 16 scan LED Driver, you can use 2 scans to drive 96 LEDs(32 RGB).

TLC69628 is 48 channels direct LED Driver, the peak current is up to 60mA and each one can drive 16 RGBs.
