Automotive RGB LED Matrix (Display) Driver Inquiry

Other Parts Discussed in Thread: LP5891-Q1

Hi, TI expert

A customer has an inquiry about a driver product or solution related to an RGB LED Matrix or Display for automotive use.

The application is a project to create a module that implements a custom pattern display by configuring 71X32 (2272EA) RGB LEDs on the front grill of the vehicle.

Customer was thinking of an individually controlled ISELED solution, but there is a request from an end customer to review a solution using general RGB LED, so if you have a similar solution or related product, please introduce it.

Please check. Thank you.

Hi Grady,

For 71*33 RGB LEDs, what's the current for each LED and the zone pitch?

We have a product suitable for this application but it's now sampling (not RTMed yet).

BR, Gracie

Hi, Gracie

The details confirmed by the customer are as follows.

For 71*33 RGB LEDs, what's the current for each LED and the zone pitch?

→ It is planned to be written in the location of the front grill.

It will be determined accurately after optical simulation, but at the moment it has not been decided whether it will be 0.2W or 0.5W.

It seems to be one of the two.

The pitch is around 4mm in review with conventional ISELEDs.

Please recommend a suitable product. (For reference, the customer has an NDA signed with TI.)

Thank you.

Hi Grady,

Then the sampling device would be quite suitable for this current and pitch. You may contact the product line via mail I provided in private message.

Thanks, Gracie
