China 3.9 inch colour TFT Manufacturer, Supplier, Factory

The VXT350EVV-01 puts 640 x 480 into 3.5 inches - 307,200 pixels at 232.0 PPI on square 0.1095 mm pixels, the sharpest 3.5-inch panel in this range. What makes it usable rather than just dense is that the optical figures come with floors: brightness 250, 320 and 440, contrast 600 minimum against 800 typical, uniformity 80 per cent minimum, and all four viewing angles identical at 75 minimum and 85 typical, which is what the ALL viewing direction promises.

This Victronix 3.5 inch Tianma Panel TFT Module offers 380 cd/m² brightness, 500:1 contrast ratio, and viewing angles of 70° horizontal / 60° vertical ensure vivid imagery. Secondly, the device supports both 24-bit RGB parallel and SPI control. Additionally, it features a 6-die white LED backlight with a lifespan of 30,000 to 50,000 hours, ensuring reliable performance in various industrial applications. Besides, it meets RoHS standards and passes rigorous reliability tests (thermal shock, humidity, storage) to operate flawlessly in extreme temperatures (-20°C to +70°C) and withstand harsh storage conditions (-30°C to +80°C). This Victronix 3.5 inch TFT Module is suitable for video door phone, smart home, GPS, camcorder, digital camera application, industrial equipment device, and other electronic products that require high-quality flat panel displays and excellent visual effects.

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 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 VXT430HNS-01-W is a 4.3-inch transmissive TFT module with 480 x 272 resolution, an anti-glare polarizer, and an operating range of -30 to +85°C, without touch. Its most useful property only appears when you compare it with a sibling: it shares the mechanical envelope, connector and pin-out of the VXT430HWE-03-W, which is the same module at 800 x 480 — same outline, same 40-pin assignment, same contrast and viewing angle — with one third the frame buffer at 255 KB. That makes resolution a choice you can defer rather than a decision that locks your mechanics. Pixels are exactly square at 0.198 x 0.198 mm, so circles, dials and round indicators need no artwork correction. Brightness is given as 440 minimum, 550 typical and 660 maximum, with contrast at 640 minimum and 800 typical. Reliability covers ten tests including vibration and 60 G shock, with MTBF of 50,000 hours. Two gaps are stated plainly: logic supply current is not published, and storage temperature is not wider than operating.

The VXT101BAH-02 is a 10.1 inch color TFT LCD module for equipment that uses separate buttons, keypads or host controls. Its landscape display and LVDS interface provide a platform for presenting menus, measurements and operating information.
