TLC6983: Required Q'ty of TLC6983

Hi Michael,

The number of device for your application mainly depends on your current request. so how much average current(R/G/B) do you need?

Hi Monet,

Thanks for your kind support.

For your reference, the type of LED is Micro LED.

The average current required for each R/G/B is 0.5mA.

Best Regards,

Hi Michael

1. Suggest using TLC6983 with 2 stackable mode. 2 device design to drive 32*30 RGB.

so 1080/30 * 1980/32 *2 = 4320 TLC6983

2. Using TLC6984 with 3 stackable mode, 3 device design to drive 48 * 40 RGB

so 1080/40 * 1920/48 *2 = 2160 TLC6984

Hi Michael,

based on the set is 950 x 534,

• if the average current is around 0.5mA,considering the scan efficiency, suggested to use TLC6983 device
  • 2 device in 2-stackable mode to drive 30 * 32 RGB
  • the IC number should be 950/32 * 534/32 * 2 = 30 * 18 * 2= 1080 devices
• if the average current is lower than 0.5mA, suggest to use TLC6984 device 
  • 3 device in 3-stackable mode8 to driver 38 * 48 RGB
  • the IC number should be 950/38 * 534/48 * 2(double sided)= 600 devices

by the way, do you have any spec about the pixel pitch? which kind of LED will you use? COB or SMT?

Hi Monet,

Pixel pitch is 2mm.

However, I didn't receive any information about what type of package it is.

Based on the pixel pitch, it seems to be SMT type.

I have a question about the IC number in the calculation you provided.

1. TLC6983

* 2 device in 2-stackable mode to drive 30 * 32 RGB
* the IC number should be 950/32 * 534/32 * 2 = 30 * 18 * 2= 1080 devices

Question

Question1, Is this for single sided?

Question2, If it is right, for double sided, the IC number should be 950/32 * 534/32 * 2(2 device in 2-stackable mode) * 2(double sided) = 30 * 18 * 2 * 2= 2160 devices

2. TLC6984

* 3 device in 3-stackable mode8 to driver 38 * 48 RGB
* the IC number should be 950/38 * 534/48 * 2(double sided)= 600 devices

Question

Question1, For single sided, I think that calculation is 950/38 * 534/48 * 3(3 device in 3-stackable mode)

                  Is it right? If I misunderstood the calculation, could you please explain the calculation formula?

If you have any calculation sheet, could you please share it?

Hi Michael,

Our expert is currently out of office and will reply to you next Monday. Thanks for your understanding.
