1. 320×240 Standard Small Resolution for Low-Cost MCU

AM-320240LQTZQW-33H adopts 3.5-inch 320×240 pixels, delivering smooth text and monitoring curves without aliasing. Low rendering workload lets 51, STM8 and other low-cost MCUs drive it fluently, ideal for teaching labs and simple testing equipment UI development.

2. IPS 85° Four-Direction Wide View

Built on original AMPIRE IPS substrate, the viewing angle reaches 85° up/down/left/right, eliminating the side-view whitening of traditional TN screens. Multiple operators at a console and hand-held oblique viewing keep consistent color and brightness, easing long-term observation.

3. RGB+SPI Dual-Reuse Interface, Wide MCU Compatibility

A single 50PIN FPC supports both parallel RGB and serial SPI protocols. Low-end MCUs and high-end ARM controllers connect directly, shipped with two complete driver routine sets, flexible hardware design and much shorter new-project development cycle.

4. 400cd/m² Uniform Long-Life LED Backlight

6S1P LED array delivers stable 400cd/m² brightness, clearly readable in ordinary workshop and clinic daylight. Slow backlight decay means no frequent screen replacement during years of non-stop operation, lowering after-sales maintenance cost.

5. -20~70℃ Wide Temp, 3.45mm Ultra-Thin Body

The module passes high-low temperature cycling aging tests, lighting up stably in winter cold workshops and summer sealed control cabinets. Total thickness only 3.45mm fits various slim hand-held and wall-mounted device housings with less assembly space.

6. Multi-Industry Small Embedded Applications

Industrial Control Equipment

Micro PLC, pipeline status monitoring small operation panels

Portable Medical Instruments

Simple vital-sign detectors, clinic small diagnostic devices

Environmental Monitoring Terminals

Water quality, temperature & humidity portable field collectors

MCU Teaching Kits

STM32/51 MCU training development supporting displays

Small Smart Controllers

Access control, temperature control wall-mounted simple panels

7. Product Selection Guidance

Low-cost MCU projects prefer 320×240 small IPS color screen;
Choose RGB/SPI dual interface version to be compatible with various main controllers;
400cd/m² brightness is sufficient for workshop and clinic indoor environments;
Select -20~70℃ wide-temp spec for equipment with large winter-summer temperature difference;
3.45mm ultra-thin module fits slim device housing design.
