Product Introduction

The CH190QV01A is a high-performance 1.9-inch IPS TFT LCD module with 170×320 resolution, 400 cd/m² brightness (driven by 4 white LEDs), and an 800:1 contrast ratio, delivering sharp, vivid visuals with excellent legibility in bright indoor or semi-outdoor environments. Leveraging IPS/Transmissive/Normally Black technology, it provides 80°/80°/80°/80° full viewing angles, ensuring consistent color and brightness from any angle—ideal for applications where off-axis viewing is common. With an ultra-compact form factor of 25.8(W) × 49.72(H) × 1.43(T) mm and an active display area of 22.7 × 42.72 mm, it fits seamlessly into space-constrained devices such as mini IoT terminals, portable medical instruments, and compact industrial controllers.
The module supports dual interfaces—8080-8bit MCU for fast data transmission and 4-line 8-bit SPI for simplified wiring—enabling flexible integration with a wide range of microcontrollers and embedded systems. Its 30-pin FPC connector ensures stable, low-profile connections without bulky hardware. Designed for reliability, it operates across –20°C to +70°C (storage: –30°C to +80°C), making it suitable for demanding environments like factory floors, field-deployed sensors, or temperature-variable clinical settings. Backlight longevity and compliance with environmental standards further enhance its suitability for long-life, professional-grade applications where clarity, compactness, and robustness are essential.
