China 5 point capacitive touch panel Manufacturer, Supplier, Factory

This Victronix 7 inch 800x480 Capacitive Touch TFT Module is a high-performance 7 inch TFT LCD module designed for industrial embedded systems. It features an 800×480 resolution screen, a capacitive touch panel (CTP), and a high-luminance backlight system within a compact form factor. As a professional manufacturer and supplier of TFT modules in China, this Victronix 7 inch TFT Module is fully compliant with ROHS environmental standards, ensuring superior application performance. We offer a customized service to meet the needs of our customers.

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 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 VXT430MPIA-03 is a 4.3-inch TFT module with a 480 x 272 RGB panel, an ILI6485D driver and a 5S2P white LED backlight, and no touch panel. It is the display-only member of a pair: the VXT430MPIA-03C is the same module with five-point capacitive touch bonded on. Comparing the two gives something most suppliers cannot show — a measured figure for what adding touch actually costs. This module is rated 500 cd/m² and the touch version 400, on otherwise identical hardware: same panel, same driver, same backlight, same timing, and CIE colour coordinates matching to four decimal places. That difference is the touch panel, and it works out at about 20 per cent of your brightness. Beyond that it is a well-documented module: 800:1 contrast minimum, a published logic current of 22 mA giving a calculable total of about 0.67 W, and full timing tables for three operating modes.

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.

The CTP-VX104B5747-GG is a 10.4-inch capacitive touch panel in G+G construction, sized for the 1024x768 industrial panels that a great deal of equipment was built around — so it is usually bought as a replacement rather than a new design. At 10.4 inches it sits just past the 10.1-inch boundary in the inspection standard, making it one cosmetic tier more permissive than sub-10-inch panels. Transmittance is ≥85% with ≥6H hardness, response ≤12 ms. Suited to industrial HMI, medical devices, CNC controls and legacy upgrades.
