China 3.5 inch capacitive touch screen display Manufacturer, Supplier, Factory

The VXT104BGH-01P is a 10.4-inch 800 x 600 SVGA TFT LCD module with a touch panel, driven over an LVDS interface on a 20-pin connector - four differential pairs, three data channels and one clock, with eight grounds and one between every pair. That is the industrial format: 480,000 pixels over a 212.20 x 158.40 mm active area, and a differential interface in place of the forty-pin parallel buses the smaller panels here need. Contrast carries a floor of 300 against 500 typical, NTSC a floor of 50 against 60, uniformity a floor of 75 per cent, and the rise and fall times are given separately at 10 ms each rather than squeezed into one row. The backlight is 36 LEDs, six in series and six strings in parallel, at 18.0 V and 120 mA for a derived 2.16 W.

This Victronix 2.4 inch 240x320 IPS TFT Module is a high-quality 2.4 inch TFT LCD module engineered for reliable performance in demanding applications. Featuring an IPS (In-Plane Switching) panel with a resolution of 240×320 pixels, it delivers wide viewing angles (80° horizontal/vertical) and vivid 262K color reproduction. Ideal for industrial controls, medical devices, and portable instruments, this module combines compact dimensions (42.72×60.4×2.2 mm) with robust engineering.

The VXT280CQI-02 is a 2.8-inch 240 x 320 portrait TFT LCD module on a 16-bit 8080 MCU bus,The colour depth is stated outright at 65K, which most specifications leave blank. The diagonal runs over rather than short: 43.20 x 57.60 mm gives exactly 72.0000 mm, or 2.8346 inches against a nominal 2.8, a margin of 1.2 per cent - the widest in this range. The backlight is four white LEDs in parallel, one anode and four cathode pins, at 3.2 V and 60 mA, which is 15 mA per LED against a 30 mA absolute maximum.

The VXT121QXHA-01 is a 12.1-inch TFT module with 1024 x 768 pixels, and it is the only 4:3 panel in our 12.1-inch range — the other two are 1280 x 800. That matters because XGA in a 4:3 layout is what a very large installed base of industrial controllers, medical instruments and test equipment was designed around, and it remains the usual target when a display in existing hardware has to be replaced. The active area is 245.76 x 184.32 mm with pixels that are square to ten decimal places, so circles and dial scales stay true. Brightness is 1000 cd/m², the highest figure we publish in this size, and the viewing angle is 85° in all four directions with no stated best direction. The interface is 4-lane LVDS on a 20-pin connector, and it runs from a single 3.3 V rail — no separate gate or analogue supplies to generate. We are equally direct about what this module demands and what is not yet documented: the backlight draws about 14 W, which is over 90% of the module's total power and needs a real thermal plan; brightness and viewing angle are given as typical values without stated minimums; and the driver IC, outline dimensions and LVDS data mapping are not in the file we hold.

The VXTA10BXH-01C is a 10.1-inch 1280x800 TFT with an integrated capacitive touch panel, driven over 4-lane MIPI DSI. Against our 10.4-inch 800x600 module it carries 2.1 times the pixels through 35% fewer pins — 39 instead of 60, and 32 functional instead of 43 — because four differential pairs move the whole image. Touch is on the module with an FT5426, so there is no separate flex to route. The backlight has PWM in and PWM out, so dimming is handled on the module rather than in your firmware. It is 16:10 at 150 PPI, anti-glare, with 80° viewing in all four directions and no gray scale inversion — together the signature of an IPS cell. Contrast is 700 minimum. The document has real problems, listed here: an active-area figure that does not reconcile, a touch controller with no I2C pins, and a brightness figure with no minimum.

The CTP-T350GF-08 is a 3.5-inch capacitive touch panel in G+F construction — the only film-sensor panel in our range, and the only one with a six-pin FPC. Its ITO film sensor is 0.125 mm against 0.55 mm for glass, so the stack is thinner and lighter even behind a 1.1 mm cover glass. It reports a single touch point, which suits button and menu interfaces rather than gestures. Rated -20 to +70°C with ±8 kV air-discharge ESD. Built for appliance controls, elevator panels, thermostats and simple HMI.
