No Fading at +70℃: ENRICH STN Yellow-Green Display Keeps Oven Control Panels Reliable Under Prolonged Heat

In laboratory settings, ovens and incubators often run continuously for days or even weeks. The displays on their control panels must remain stable under such prolonged high-temperature conditions, clearly showing critical parameters like temperature and timing. Many ordinary displays suffer from contrast drop, character fading, slow response, or even permanent damage when exposed to heat—an unacceptable risk for experiments that rely on precise data.

ENRICH introduces an STN yellow-green positive segment LCD specifically engineered for high-temperature environments. With exceptional thermal stability and high-contrast visibility, it is the ideal choice for laboratory oven and incubator control panels.

STN Yellow-Green Technology: Clarity Under Heat
In conventional TN displays, liquid crystal molecules tend to lose their twist elasticity at high temperatures, causing contrast to plummet. ENRICH’s STN (Super Twisted Nematic) yellow-green positive technology uses a more stable liquid crystal formulation, maintaining high contrast between the yellow-green background and black characters even at +70℃. Lab personnel can read temperature values, countdown timers, and operating status at a glance—without squinting.

-20℃ to +70℃ Wide Temperature Range: From Cold Start to Hot Operation
Laboratory equipment may be powered on directly after being taken from cold storage. ENRICH’s display offers an operating range of -20℃ to +70℃ and a storage range of -30℃ to +80℃. Whether it‘s a cold start on a winter day or prolonged heating inside an oven, the screen responds instantly and remains clear—no ghosting, no fading.

6:00 Viewing Angle: Optimized for Horizontal Placement
Oven and incubator control panels are typically mounted horizontally or with a slight tilt, viewed from a standing position. ENRICH’s 6:00 viewing angle is optimized for this scenario, delivering peak contrast when viewed from slightly above. No bending, no head-tilting—parameter reading is effortless.

1/8 Duty Low Power: Cool Operation Under Continuous Run
Long-running equipment is sensitive to internal heat buildup. ENRICH’s display uses a 1/8 duty cycle, 1/4 bias drive, minimizing power consumption while supporting plenty of display content. Paired with 3.0V low voltage, the screen generates almost no extra heat, adding no thermal burden to the oven’s control system.

6 Yellow LED Backlights: Gentle Illumination in Low Light
Laboratory lighting conditions vary—fluorescent tubes, window sunlight, even darkroom observation. ENRICH equips the display with 6 yellow LED backlights. Yellow light is softer and less glaring than white, and offers better penetration through mist or dust particles. When lab personnel check readings in dim conditions or at night, the screen remains clearly visible without disturbing other experiments.

PIN Connection and HT1622 Driver: A Foundation of Stability
Laboratory equipment may experience mild vibration (e.g., near a centrifuge). ENRICH’s PIN connection provides a secure, vibration-resistant attachment. The HT1622 driver IC supports multiple segments, allowing simultaneous display of temperature, humidity, time, and other parameters—meeting the complex data presentation needs of ovens and incubators.

When high heat is the norm, ENRICH STN yellow-green display keeps your data vivid. Long-term stable, reliably clear—safeguarding precision experiments.
