The VXT350LQZ-01P is a 3.5-inch 320 x 240 QVGA TFT LCD module with a 4-wire resistive touch panel, and the touch specification is the reason to look at it. Section 6 publishes what almost nothing in this size does: linearity of +/-1.5% after environmental and life testing, terminal resistance per axis, insulation resistance of 20 megohms minimum, response time under 10 ms, light transparency of 78% minimum, operation force of 80 gf typical, surface hardness of 3H minimum, 100,000 pen sliding cycles and 1,000,000 hitting cycles - with the test conditions for each. Two other figures are unusually trustworthy. Brightness carries both a floor and a ceiling, 280 minimum and 420 maximum around the 350 typical, so you can see the production spread as well as the worst case.The viewing angles are the narrowest in our range at 25 degrees typical on one horizontal side and 45 everywhere else, and while the specification states a 6 o'clock viewing direction, it is the horizontal pair that is asymmetric rather than the vertical one - so confirm the orientation with us and expect a narrow cone.

The VXT430MBVS-03 is a 4.3-inch TFT LCD module with 480 x 800 pixels in portrait. The active area of 56.16 x 93.60 mm is taller than it is wide by an exact 5:3, matching the pixel count, and the pitch works out to 0.117 mm on both axes - square, so circles and dial scales need no correction. Pixel count is 384,000, identical to an 800 x 480 landscape panel: a portrait interface is a transposition of what you already have, and the frame buffer is the same 750 KB at RGB565. One detail saves a component. Logic IO runs from a separate 1.8 V rail, and with VIH at 0.7 IOVCC a 1.8 V host drives it directly - no level shifters, which is not the case on the 3.3 V IO modules elsewhere in this size. Images travel over 24-bit RGB with a real data-enable line, and the driver is configured over a 3-line serial interface, so both paths are on the one 45-pin FPC. Contrast carries a stated 700 minimum against 1000 typical, uniformity 80% minimum, and viewing angle 85 degrees in all four directions with no preferred orientation.

The VXT500BKI-01F is a 5.0-inch TFT LCD module with 720 x 1280 pixels in portrait - HD resolution on a five-inch panel, and one of the highest pixel densities in our range. The pixels are square: 0.08625 mm on both axes, which is exactly what 62.1 mm over 720 pixels and 110.4 mm over 1280 pixels both give, and the shape is an exact 16:9 turned on its side. Brightness is 680 cd/m2 minimum against 850 typical, contrast 1000:1 minimum, and viewing angle 70 degrees minimum in all four directions with no preferred orientation, so how you mount it is a mechanical decision rather than an optical one. Touch is five-point capacitive in a G+G stack rated at 6H and 85% transparency, on its own 7-pin I2C connector. The display runs four MIPI lanes from a single 2.8 V rail, and both the logic current and the backlight power are published, so the total draw can be worked out at roughly 0.93 W.

The CTP-VX185A2132 is an 18.5-inch capacitive touch panel in G+G construction, and the only panel in our range with a USB interface — so it works the moment you plug it in, with the multi-touch HID driver already in Windows, Linux, macOS and Android. There is no I2C address to configure and no level shifting to worry about. Ten-point touch, a 409.8 x 230.4 mm active area matched to 1366x768, powered from 5 V. Built for kiosks, information displays, POS and interactive screens.

The CTP-VX116B5741-GG is an 11.6-inch capacitive touch panel in G+G construction, sized for 1366x768 displays. Transmittance is at least 85% with ≥6H hardness, response is ≤12 ms. Suited to portable terminals, industrial tablets, POS, medical devices and vehicle displays.

The VXT084XJWA-01 is an 8.4 inch XGA TFT LCD module with a 4:3 viewing area for instruments and monitoring interfaces. Wide viewing angles, adjustable backlighting and an extended operating temperature range support equipment integration.
