China 11.6 inch touch screen for industrial tablet Manufacturer, Supplier, Factory

The VXT350CHH-08C1 is a 3.5-inch 320 x 480 portrait TFT LCD module with a capacitive touch panel, G+G construction with a 0.7 mm toughened cover lens over 0.55 mm sensor glass, 1.4 mm total thickness, FT5443DQS over I2C, 2.8 to 3.3 V supply with 1.8 V IO, 85% minimum light transmittance, 6H surface hardness, 0.25 J impact energy and 5 touch points. Brightness is the other strong figure: 600 cd/m2 typical with a stated minimum of 480 and a stated maximum of 720, so you get a floor to hold us to and a ceiling that shows the production spread. And the backlight reconciles: 19.2 V over the six dies the block diagram states gives exactly 3.20 V per LED, and the stated 0.768 W matches 19.2 V x 40 mA exactly.

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.

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 VXT350MSGV-01 is a 3.45-inch TFT module with 640 x 480 pixels — standard VGA in the classic 4:3 shape — over an active area of 70.08 x 52.56 mm. At 232 PPI it is the highest-density module in this size class, carrying four times the pixels of the 320 x 240 modules that share this identical active area: 307,200 against 76,800. Small text becomes readable, fine graphics render as drawn, and pixels are exactly square at 0.1095 mm so circles need no correction. It runs 24-bit RGB for video and 3-wire SPI for configuration on one 40-pin connector driven by an NV3052C, with DE and SYNC timing charts both provided. Contrast is given as a 600:1 minimum, and viewing angle is 80° in all four directions with viewing direction ALL, so mounting orientation is a mechanical decision only. The backlight is six LEDs in series at just 20 mA — half the current of most modules this size, at 0.36 W. Reliability covers nine tests including vibration, random vibration and 100 G shock.

The VXT430MPIA-03C is a 4.3-inch TFT module with a five-point capacitive touch panel bonded on: a 480 x 272 RGB display and an I2C touch controller in one assembly. What sets it apart is practical rather than headline — this is the 4.3-inch module whose power you can actually budget, because it publishes a logic current of 22 mA where the sibling module rated identically leaves it as TBD. Total draw is about 0.67 W, the lowest of any 4.3-inch module we offer with touch. It is also unusually complete on the touch side: accuracy of ±1.5 mm at the centre and ±2.5 mm at the edge, surface hardness of at least 7H, and transparency of at least 85% are all given as numbers. Contrast is 800:1 minimum with 80° viewing in all four directions. Two things need attention before ordering, and both are stated here: the module matches a sibling part on every comparable figure apart from the driver IC, and its reliability programme is shorter than the rest of the range.

The VXT700MYIA-03C is a 7-inch front panel assembly: a display and touch stack under a custom cover glass carrying three functional openings — a camera window, a proximity sensor window and a microphone through-hole. The ink over the openings is specified with a number you can measure: visible light transmittance at 520 nm below 25%, which is what lets the proximity sensor hide behind the glass while still passing IR. Everything runs on one 40-pin flex at 0.30 mm pitch, and that flex carries the LED backlight as well, so there is one connector rather than two. The glass has an anti-fingerprint coating, there is black electromagnetic shielding on both sides, and the section gives a 2.25 mm finished stack with component height capped at 1.8 mm. This is a mechanical drawing, so the page is explicit about what is not in it: no resolution, interface, pin assignment, optical or environmental data.
