Engineering Change Notification 04/16/2020
This notice on April 16th 2020, is to inform you of a change to the following 7" TFT products:
The TFT Panel and Driver IC used in the manufacturing of these products have changed for improvements in performance.
The old panel had a contrast ratio of 400:1. The new panel has a contrast ratio of 500:1.
All our testing has found the new display to be backwards compatible with existing systems without the need for any hardware or software modifications.
As with any compatible ICs made by different manufacturers, slight variations in timings and tolerances are present between the old and new driver ICs.
Please use the links below for a detailed comparison.
Old Driver IC Datasheet: HX8264
The new displays will be labeled with a Rev1A identified after the part number.
We understand that every customer’s application is unique, and therefore recommend you test and validate samples of the updated design.
