H121HHD20I1K001-CT1 is a 12.1 inch TFT LCD module with capacitive touch function. The capacitive touch screen supports multi-touch, has fast response and no pressure required, and is highly sensitive and smooth to operate. This LCD panel uses IPS panel technology to provide full viewing angles and rich display colors. The resolution is 1024×768 (XGA), with moderate pixel density, and the display of text, images and videos is clear and detailed, providing a high-definition visual experience. The LVDS 20PIN interface, with a 900nit high brightness design, can maintain clear display even in outdoor or strong light conditions. It is made of reinforced glass and impact-resistant materials, capable of withstanding external impacts and scratches. The working temperature can withstand -10℃ to +60℃, and can adapt to harsh environments such as industrial and vehicle use.

Frequently Asked Questions
What is the resolution and panel type of the H121HHD20I1K001-CT1?
The H121HHD20I1K001-CT1 features a 12.1-inch IPS TFT LCD panel with a resolution of 1024×768 (XGA). The IPS technology ensures full viewing angles from all directions and rich, accurate color reproduction with a 16.7M color depth.
Does this LCD module support touch input, and what type of touch technology is used?
Yes, the H121HHD20I1K001-CT1 is equipped with a capacitive touch screen (CTP) that supports multi-touch gestures. It requires no physical pressure to operate, offers fast response times, and provides a highly sensitive and smooth user experience.
Can the H121HHD20I1K001-CT1 be used in outdoor or high-brightness environments?
Absolutely. This module features a high brightness of 900 cd/m² (nits), which makes it well-suited for use in direct sunlight, outdoor kiosks, industrial environments, and other high ambient light conditions where standard displays would appear washed out.
What interface does the H121HHD20I1K001-CT1 use and what are the pin definitions?
The module uses an LVDS 20PIN interface. The 20 pins cover differential data inputs (CH0–CH3), differential clock inputs, ground (GND) pins, power supply (VDD at 3.3V), and control signals including BIST mode select, SEL68 for 6/8-bit data selection, and display direction controls (reLR and reUD).
What is the operating temperature range of this LCD module?
The H121HHD20I1K001-CT1 has an operating temperature range of -10℃ to +60℃ and a storage temperature range of -20℃ to +70℃. This makes it suitable for use in demanding environments such as industrial facilities, vehicles, and outdoor equipment.
What are the physical dimensions of the H121HHD20I1K001-CT1 module?
The overall dimensions of the LCM + CTP assembly are 286.5mm (W) × 225mm (H) × 12.19mm (D). The active display area measures 245.76mm × 184.32mm. The module is constructed with reinforced glass and impact-resistant materials to ensure durability in challenging application environments.
