This report assumes the IC is the Goodix GT911 (the most common in the GT9XX family for this resolution), as the GT915 and GT928 share similar architecture but differ in maximum touch points and reporting ID.
Patient monitors, portable ultrasound viewers, and infusion pump interfaces require reliable touch response. The LVDS interface ensures noise immunity in MRI or RF-rich environments.
The GT9xx reports touch coordinates as 16-bit values. Ensure correct orientation: gt9xx1024x600
Normal landscape (1024 wide, 600 high):
If your LCD rotates 90°/180°, swap or invert axes in software, or adjust the swap_xy and mirror registers (0x8050, 0x804E). This report assumes the IC is the Goodix
While exact figures depend on the specific GT9XX sub-model, most units in this family share the following core characteristics:
| Parameter | Typical Value | | --- | --- | | Screen Size | 10.1 inches diagonal | | Resolution | 1024 (RGB) x 600 | | Aspect Ratio | 16:9 | | Pixel Pitch | 0.2175 (H) x 0.2085 (V) mm | | Active Area | 222.72 (H) x 125.28 (V) mm | | Display Mode | Normally Black, Transmissive | | Viewing Direction | IPS (typically 85/85/85/85) or TN (70/70/50/70) depending on variant | | Interface | LVDS (Low-Voltage Differential Signaling) or RGB 24-bit parallel | | Touch Panel | Capacitive (GT911, GT928) or optional Resistive | | Operating Temp | -20°C to +70°C | | Storage Temp | -30°C to +80°C | | Backlight | LED array (typical 300–500 cd/m² brightness) | X ranges 0–1023 Y ranges 0–599
The LVDS interface is a standout feature for the GT9XX1024x600. Compared to older parallel RGB interfaces, LVDS uses fewer pins, supports longer cable runs, and is resistant to electromagnetic interference (EMI)—critical for industrial environments.
