3.5" 320x240 Anti-Glare TFT LCD Module Wide Temperature - VXT350HQS-01X-W

The Anti-Glare Polarizer: Reflections Removed, Not Outshouted

Most display modules leave the factory with a glossy top polarizer. Under a bright light that surface behaves like a mirror, and what the operator sees is not the screen but the ceiling lamp, the window behind them, or their own reflection. The usual reflex is to specify more brightness.

That works, but it is the expensive way round the problem.

The anti-glare treatment is built into the polarizer itself, so there is no additional part, no lamination step and nothing to delaminate. It does not consume power, so it does not add heat to a sealed enclosure, and it does not shorten the backlight. It simply stops the front surface from behaving like a mirror.

The honest trade is that a matte surface adds a very slight haze, which costs a little perceived sharpness when you hold the display very close. For a 3.5-inch panel read at arm's length on a bench, in a vehicle, or on a machine, that is a good trade. If your product is a close-viewing optical instrument, ask us about the glossy version instead.

Two more ratings that make it work

Rated -30°C to +85°C

Operating range is -30°C to +85°C, among the widest in our range and ten degrees better than a typical -20 to +70°C panel at both ends. In practice the rating removes hardware rather than just surviving conditions:

• No fan or vent for a sealed enclosure that gets hot in summer.
• No heater for equipment shipped to cold climates.
• One part for all markets rather than a temperate and a cold-climate variant.
• Fewer things to fail later — a fan and a heater are two more components with bearings, filters and contacts.
