8.0 Inch 800x1280 Portrait TFT LCD Module MIPI DSI - VXT800BYH-01

The VXT800BYH-01 is an 8.0-inch 800 x 1280 portrait TFT LCD module driven by an HX8260 over a 4-lane MIPI DSI interface on a 24-pin FPC, and the reason a panel this size ships on 24 pins is the interface. Four differential data lanes plus one differential clock pair carry what a 24-bit parallel RGB bus would need fifty pins to carry, so a 1,024,000-pixel display fits a host with a DSI peripheral and almost no other pins to spare. It is the most portrait panel here - 800 x 1280 in a 16:10 column - with square 0.13455 mm pixels at 188.8 PPI, 16.7M colours stated outright, and a diagonal of 203.09 mm that lands within 0.05 per cent of the nominal 8.0 inch. And TE is brought out on pin 4, which is the tearing effect output: with a 2.0 MB frame buffer too big to double cheaply, being able to stay single-buffered and still write tear-free is the difference between a workable design and an expensive one. Three things need settling before you commit. The logic voltage is stated two ways and they do not agree: pin 7 is annotated IOVCC 1.8V while the electrical table's supply-voltage-for-logic row gives 2.8 V typical, and the thresholds are written as fractions of VDD without saying which rail, so a 1.8 V host is either comfortably inside or well outside depending on which figure holds. The storage temperature runs -30 to +70 against an operating range of -20 to +70, so the high end is not wider at all - storage should be wider at both ends and here it is not. And the backlight's seven-in-series array is derived rather than stated, and it puts 27 mA through each string against a 30 mA absolute maximum.
