China 3.5 inch G+F touch screen panel Manufacturer, Supplier, Factory

The VXT397IWI-01P is a 3.97-inch 480 x 800 portrait TFT LCD module with a 4-wire resistive touch panel, and the touch is what distinguishes it from the other 480 x 800 panel in this size.Resistive sensing responds to pressure rather than to a finger's conductivity, so it works with gloves, wet hands, a stylus or a tool tip, which is why it is still the choice for industrial and medical equipment. The optical table is also unusually well specified: luminance carries a stated minimum of 240 and a stated maximum of 420 alongside the 300 typical, and contrast carries a 300 minimum, so there are figures you can hold us to at incoming inspection - which is not the case on several modules in this size. Two things need settling before you commit. This is a TN panel: the specification states a 6 o'clock viewing direction, grey-scale inversion at 12 o'clock, and vertical viewing angles of 50 degrees one way and 25 the other, so mounting orientation has a right answer - if your product is handheld and the orientation is not under your control, the IPS panel also in this size is the better buy.

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 VXT500BWEF-01 is a 5.0-inch transflective TFT LCD module with 800x480 resolution — the only transflective panel in our range. It reads in sunlight by reflecting ambient light rather than outshining it, and the backlight can be dimmed or switched off outdoors, cutting power sharply. Brightness is 200 cd/m² with 60:1 contrast and a 15 ms response, the fastest we specify. The panel is a 6 o'clock type and the logic rail runs from 2.5 V to 3.3 V. Rated -20 to +70°C.

The VXT430BPSA-04 is a 4.3-inch TFT LCD module with 480x272 resolution and a true 24-bit RGB888 interface, supplied without touch. It shares its entire electrical and mechanical platform with our VXT430MPSA-16 and differs in one figure: a 20,000-hour backlight instead of 50,000. That makes it the choice where a display can be serviced easily — supervised indoor equipment, machine panels, instruments — rather than unattended installations where a service visit costs more than the panel. Rated -30 to +80°C.

The VXT397FBWS-01 is a 3.97-inch transflective TFT LCD that combines ambient-light reflection with LED backlighting. An anti-glare surface and compact portrait format support integration into handheld instruments and space-conscious equipment.

The VXT104QXHA-03 is a 10.4 inch XGA TFT LCD module with high brightness, wide viewing angles and PWM backlight control. Its LVDS interface and wide operating temperature range suit integration into industrial equipment and embedded display systems.
