10.1 Inch 1280x800 MIPI TFT LCD Module 2.9mm Without Touch - VXTA10BXH-01

2.9 mm, and why that number is worth something

Two and a half millimetres does not sound like much until you are working inside a fixed enclosure depth. Consider where it goes:

• Behind the panel. Every millimetre you do not spend on the display is a millimetre available for the board, the battery, the connector stack or the standoff height.
• In the bezel. A thinner module lets the front surface sit closer to the panel plane, which is what a flush-mounted design needs.
• In the stack-up. If you are adding your own cover lens and touch layer anyway, starting from 2.9 mm instead of 5.15 mm leaves far more room before the assembly becomes too deep for the housing.

PWMI and PWMO: dimming handled on the module

You feed a PWM signal in on pin 30; the timing controller produces the output on pin 26 to drive your LED driver. That takes dimming — its frequency, duty step and ramp — out of your firmware and puts it on the panel designer. Dimming is one of the things most often added late and done badly: too low a frequency beats against cameras and eyes, too coarse a step flickers at low brightness, and a naive implementation lets the backlight surge at power-up. Confirm the expected PWMI frequency and polarity with us before layout — the specification names the pins but not the timing.
