China touch panel for interactive whiteboard Manufacturer, Supplier, Factory

The VXT140HSS-01 is a 1.4-inch 240 x 240 square TFT LCD module driven by ST7789V2, selectable between 8080 MCU parallel (8-bit, D0-D7) and 4-line SPI by a single IMX strap pin, on a 20-pin FPC at 0.5 mm pitch. It suits square and round wearable UI, compact instruments and small control panels. The active area is genuinely square at 25.20 x 25.20 mm, matching the 240 x 240 dot matrix exactly, Brightness 800-1100 cd/m2 , contrast is 900 typical, all four viewing angles are 80 degrees with an ALL viewing direction. The module is 30.00 x 35.00 x 2.20 mm with a 0.128 W backlight from two LEDs. Three things need settling first: the SDA pin description depends on IM3, which has no pin on the connector, and no pin is named SCL although 4-line SPI requires one; the timing chapter is images only, recovered here by OCR, and is specified against a VDDI rail that does not exist on the connector; and the packing table lists module dimensions of 105.5 x 67.2 x 3.0 mm against 30.00 x 35.00 x 2.20 in the general specification.

Victronix VXT350QHI-19: a 3.5 inch portrait TFT LCD module with 320x480 pixels and 262K colors over a 48.96 x 73.44 mm active area. All viewing direction with free grey-scale inversion and 80 degrees at 3, 6, 9 and 12 o'clock alike, so there is no wrong mounting orientation. RGB, MCU and SPI interfaces on one 50-pin FPC selected by IM0, IM1 and IM2, ILI9488 controller, VCI 2.8 V and IOVCC 1.8 V rails so 1.8 V logic drives it directly, 6-LED backlight, 2.25 mm thin, -20 to +70 C operating. For handheld instruments, portable monitors, smart home control panels, POS terminals, medical devices and industrial HMI.

The VXT104QXHA-02-B is a 10.4-inch TFT LCD module with 1024 x 768 XGA resolution and an HDMI input — the first HDMI module in our range, and the difference is the point. Every other module we sell is a component you have to drive: your processor needs the right peripheral, your firmware needs an initialisation sequence, your board needs a frame buffer, and your power design needs the sequencing right. This one includes the driver PCBA, so it takes HDMI from a single-board computer, an industrial PC, a media player or a laptop and shows a picture. There is no display interface to design and no 1.5 MB of frame memory to find in your host. It is also the easy answer when an old XGA panel fails: you do not have to reproduce the original interface, just feed it HDMI from the new computer. Power comes from a 12 V DC jack or 5 V over the HDMI connector, with the jack recommended because no input current is published. Brightness is 600 cd/m² with contrast at 600 minimum and 800 typical, viewing angle 80° in all four directions, and pixels square to within 0.002% so circles need no correction. We are equally plain about what the document does not settle: no LED forward voltage or backlight power, no input current, brightness and viewing angle carry typical values with no minimums, the supported HDMI video modes are not listed, and the outline drawing is missing from the file.

The VXT400MCCA-01 is a round TFT module: 720 x 720 pixels in a square array with a circular active area of 101.52 mm diameter. It is the largest round module we offer — the others are 1.6 and 2.1 inches — and at 720 x 720 the highest resolution, at 180 PPI. The round shape suits products whose face is already circular: instrument gauges, thermostats, rotary controls, speaker and hub covers, and automotive clusters. Designers should know that the circle covers only 78.5% of the pixel array, so the four corners are invisible and content must stay within about 45 mm of centre. It runs MIPI DSI with four data lanes, and the capacitive touch interface sits on the same 30-pin connector — interrupt, I2C, reset and two dedicated supply pins — so one flex and one socket cover display and touch. Separate 1.8 V and 3.3 V rails mean 1.8 V host logic connects directly with no level shifting. The module is 2.09 mm thick, the thinnest in this size class.

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.
