M121AW81 R0 is an 11.8-inch liquid crystal module product developed by Kunshan Longteng Optoelectronics Co. (Longteng, IVO) using a-Si TFT-LCD technology. It is fitted with WLED backlighting, no backlight drive, and no touch. As an IPS, often black display, transmission LCD module products, M121AW81 R0 can provide 750 cd / m2 display brightness 1000: 1 transmission contrast,As well as the viewing angle of 85 / 85 / (85 (Typ.) (CR ≥ 10) (L / R / U / D), the optimal viewing angle is full view, and its response time is 25 (Typ.)(Tr + Td) ms. With an 8-bit grayscale signal per pixel, the product can display 16.7M colors and display 72% color saturation (NTSC). Backlight aspects of this product uses 8S4P WLED light-emitting side light source, the service life of the light source is 50K hours, without backlight drive. The M121AW81 R0 features an LVDS (2ch, 8-bit) signal interface with a total of 40 pins, terminal connections and a drive voltage of 3.3 V (Typ.). Its typical vertical refresh rate Fv is 60 Hz.Its working temperature is -40 ~ 85 ° C, storage temperature is -40 ~ 95 ° C, and vibration resistance is 2.9 G (28.4 m / s2).Based on its portrait mode, wide temperature, 3G earthquake resistance, high brightness, white LED backlighting, life of more than 50,000 hours, surface fog surface, etc., this model is recommended for outdoor brightness, vehicle display, etc.
