PDF datasheet for the PW065XS4 TFT panel, revision 1.1 per the name, roughly 486 KB. The PW prefix follows the PVI naming pattern, and 065 points to a 6.5 inch class display. The document typically includes pin definitions, power sequencing, signal timing, backlight specifications and mechanical outline. Use it to measure correct voltages on the connector or to check whether another panel can be fitted. Variants with different suffix numbers may have other pinouts, so confirm the label matches PW065XS4.
