Design Engineer's defining Display technology are also defining their own reputation.

Experienced Design Engineer's face pressure in Display component and module selection, especially when their HMI Design falls prey to a display EOL scenario. The consequences can be brutal; commercially, technically and from a manufacturing standpoint.

Suddenly production halts, revenues are affected, the reputational damage is significant.

How Does Halo Design for Longevity.

Looking specifically at TFT design and production, the two main high risk design components are the Mother-Glass and TFT Controller IC.  Halo has developed a dual source approach.

Firstly let's focus on the Mother-Glass. Instead of waiting for one of the only global sources (CMI, AUO, BOE, Sharp, CPT etc) to announce a substrate becoming EOL, Halo designs for longevity from day one. This means that any display you select from Halo, will already have a dual source Mother-Glass. That way, if the primary source is made obsolete, our client's enjoy a secondary option, form , fit and function identical, pin to pin compatible, with minor optical nuance the only concern posed to continuity of supply.

Secondly if the TFT IC changes, Halo can adopt the next iteration of IC, and maintain design compatibility by adapting Mother-Glass timing and drive characteristics to the IC,as well as engineering a pin to pin forwarc and backward compatible pin configuration for the FPC.

 

Quite simply, don't take longevity for granted. The philosophy of mitigating risk of EOL at the design stage is paramount in safeguarding client reputation, and business relationship.
