China 2.3 inch QVGA display Manufacturer, Supplier, Factory

The VXT430PNO-01 is a 4.3-inch TFT LCD module at 480 x 272, The specification states the recommended viewing direction as ALL and names the technology as MVA, gives 80 degrees in all four directions, and leaves the grey-scale inversion direction blank - three consistent signals that mean there is no wrong way to mount it. On a TN panel a preferred direction and an inversion direction are stated, and a unit mounted where the operator looks up at it can land on the wrong side; here that decision disappears. The frame buffer is 255 KB, small enough that a microcontroller with 512 KB of internal SRAM needs no external RAM at all. Luminance is 280 minimum against 350 typical and 420 maximum, so there is a floor to hold us to and a ceiling that shows the spread. The backlight is twelve LEDs in six series strings of two, at 19.2 V and 40 mA drawing 0.768 W, with 30,000 hours minimum life. Reliability runs nine tests at 240 hours including vibration, ESD and an MTBF of 50,000 hours. Two cautions.

The VXT620HWI-01 is a 6.2-inch TFT LCD module with 800 x 480 WVGA pixels on a 24-bit parallel RGB interface, and its most useful property is not a headline number but how the optical table is written. Luminance is given as 400 minimum, 500 typical and 600 maximum. Contrast carries a 480 minimum against 600 typical. Uniformity is 70% minimum. The module runs on an ILI6123H and ILI5480. Ratings are -20 to +70 °C, and reliability runs 240 hours per condition with 100 thermal shock cycles and 100 G mechanical shock.

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 VXT430MPSA-16 is a 4.3-inch TFT LCD module with 480x272 resolution and a true 24-bit RGB888 interface, built around a backlight rated for 50,000 hours — the longest in our range and roughly two and a half times the 20,000-hour life of our high-brightness 4.3-inch module. Sixteen LEDs share the load across eight series pairs, which is why it lasts. It ships without touch, so you fit your own or none at all. Rated -30 to +80°C for panel and control equipment that runs continuously.

The CTP-VX215A5698-GG is a 21.5-inch capacitive touch panel in G+G construction, sized for 1920x1080 displays and for the enclosures, VESA mounts and kiosk cabinets already built around that format. It adds touch to an existing panel instead of replacing the whole assembly. Transmittance is at least 85% with ≥6H surface hardness, response is ≤12 ms, and it runs from 2.8 to 3.3 V. Suited to kiosks, POS, industrial HMI and education displays, and to retrofitting touch onto existing 21.5-inch hardware.

The VXT270AUOP-01C is a 27 inch HMI display module with Full HD resolution, 10-point capacitive touch, 300 cd/m² brightness and a 3000:1 contrast ratio. Dual-channel LVDS and USB touch support integration into industrial control systems.
