What LCD is this? and the Driver Chip? #1

Closed Helder1981 closed 3 years ago

This looks like a custom made LCD or a standard LCD with custom Flex on it. Can you tell us what the original LCD was or the driver IC it uses so other LCDs can be used.

Thanks.

The original screen we used is a SAEF SF-TC154B-8377A-N which used to be available on Alibaba, but this is no longer the case.

You can find its datasheet here: ALIBABA_SAEF_SF-TC154B-8377A-N_annote.pdf

It uses an ST7789V integrated driver IC.

Our current screen is no longer manufactured by SAEF, but our changes to the orignal model are:

change the flex shape and dimensions
add the TE (Tearing Effect) signal from the driver IC on the connector (pin 9)

Here is our current screen spec: DISPLAY - SF-TC154B-8737A-N - CUSTOM FLEX - 0.3.PDF
