The VXT350CQH-05 is a 3.5-inch 320 x 240 QVGA TFT LCD module, and two things about it are worth knowing before anything else. It is 3.2 mm thick, the thinnest module in this range on the same 76.90 x 63.90 mm footprint, and it carries no touch panel - so if your product has a separate touch solution, or none, you are not paying for one. The backlight is confirmed twice over: the mechanical drawing shows the LED circuit as six dies in one string from LEDA to LEDK, and 19.2 V over six gives exactly 3.20 V per LED, while the stated 0.384 W matches 19.2 V x 20 mA exactly. Response time is also better documented than usual, with both Ton and Toff published and floors on each - 15 and 30 ms on, 35 and 50 ms off - and contrast carries a 200 minimum. Two things need settling before you commit. This is a TN panel: the specification states a 12 o'clock viewing direction with grey-scale inversion at 6 o'clock, and vertical angles of 50 and 60 degrees, so mounting orientation has a right answer - if your product is handheld and the orientation is not under your control, ask us about a panel with no preferred direction. And the timing chapter runs three pages and is published entirely as diagrams, with a note saying the sequences are for reference only and referring you to the HX8238D data sheet, so there is nothing in this document to configure a controller from.
