China high brightness 4.3 inch TFT Manufacturer, Supplier, Factory

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.

Victronix 3.5'' 480x800 IPS TFT Module VXT350BVS-04，its IPS technology provides consistent color and clarity across wide 80-degree viewing angle in all directions, 450 cd/m² typical brightness, 16.7M colors and a high typical contrast ratio of 1000:1. Secondly, it supports both SPI (3-line serial) and high-speed 24-bit RGB parallel interfaces (configurable for 18/16-bit), offering seamless integration with diverse systems. Besides, it features a 7S white LED backlight system with a lifespan of 20,000 to 50,00 hours, maintaining 50% brightness retention, which ensures long-term usage in various industrial applications.

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.

Victronix VXT430TWH-06P is a 4.3-inch TFT LCD module in portrait, and it carries a four-wire resistive touch panel. That combination is easy to overlook and hard to replace. A resistive panel responds to pressure rather than to a finger's conductivity, so it works with gloves, wet or oily hands, a stylus, or the tip of a tool, and it costs less than a capacitive stack — at the price of multi-touch, of 80% transmittance against the 85% a capacitive panel gives, and of a surface that takes a deliberate press. The shape suits a vertical column: the active area is taller than it is wide, so readings stack one per row, scrolling lists and status panels fit naturally, and a portrait enclosure needs no rework. The display itself runs 24-bit RGB on a 40-pin FPC from a single 3.3 V rail, and 130,560 pixels need only 255 KB of frame buffer — small enough that a microcontroller with 512 KB of internal SRAM needs no external RAM at all. Most optical figures carry a stated floor: 310 cd/m² minimum brightness, 400 minimum contrast, 80° minimum viewing angle. Two things want settling before you commit, and we set them out rather than leave them for bring-up: the specification writes the resolution as 480 × 272 while the geometry says the panel is 272 wide by 480 tall, and the driver IC is named two different ways in two different places.

The VXT174MYKH-01 is the smallest TFT module we make and the second transflective one in our range. At 1.74 inches in a 40.77 × 36.20 × 2.40 mm footprint, it is sized for something worn or carried — and transflective means the backlight can be switched off entirely in daylight, not merely dimmed. With a 3.0 V backlight needing no boost converter and a 60 KB frame buffer needing no external RAM, three power savings stack in one display. Rated -30 to +70°C.

The Victronix VXT700QAEW-01C is a 7.0-inch TFT LCD module that ships as a finished touch assembly rather than a bare panel. A projected-capacitive sensor, G+G construction, 6H surface hardness, at least 85% light transmittance — so there is no second touch part to source, no alignment step and no bonding process in your build. Luminance is 1000 cd/m² typical with an 80/80/80/80 viewing angle, video arrives over 40-pin LVDS driven by EK79001HN and EK73215BCGA, with an ILI2130 touch controller. Rated -30°C to +85°C, RoHS compliant.
