China 21.5 inch capacitive touch panel 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 2.8 inch QVGA Capacitive Touch TFT Module is a high-performance 2.8 inch TFT LCD module featuring integrated capacitive touch control. Designed for embedded industrial applications, it combines a bright QVGA display, 5-point touch interface, and robust construction in a compact 59.5 × 83 × 3.85mm form factor. As a leading manufacturer and supplier of TFT modules in China, we are proud to offer the Victronix 2.8 inch TFT Module. This product not only complies fully with ROHS environmental standards, ensuring exceptional performance in various applications, but we also provide customized services to meet our customers' specific needs.

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 VXT350MLH-03P is a 3.5-inch 320 x 240 TFT LCD module with a 4-wire resistive touch panel, and resistive sensing works with gloves, wet hands or a stylus. The brightness 200 cd/m2 minimum with the touch panel fitted, contrast 300 minimum and NTSC 50% minimum - and because brightness is also published without the touch panel at 300 cd/m2

The CTP-T700GA-51 is a 7-inch capacitive touch panel in G+G construction, and the only panel in our range with true ten-point multi-touch — the other three 7-inch panels all stop at five. That matters for two-person operation, multi-finger gestures and collaborative interfaces. An Atmel maXTouch 641T controller drives a 16 by 28 channel grid, behind a 1.1 mm cover glass rated at 6H with impact energy of at least 0.35 J. Suited to collaborative terminals, education displays, industrial HMI and kiosks.

The VXT686BZSA-01 is a 6.86-inch bar-type TFT LCD for elongated display layouts. With 16.7 million colors and wide viewing angles, the module provides space for status indicators, menu items and operating information in compact equipment panels.
