Detail Information

12.8-Inch Optical Bonded Capacitive Touch Display

JT128TM001-V2 is a 12.8-inch CTP + LCD module with 1920 × 1080 resolution, LVDS video and USB / I2C touch interfaces. It combines a G+G touch structure with optical bonding, an ILI2511 controller, 10 touch points and an etched anti-glare surface.

This page is based on the preliminary specification dated January 12, 2026. Optical-table luminance is 560 nits typical with CTP. The mechanical drawing separately lists 800 nits; this discrepancy requires confirmation before design approval. No 800-nit or sunlight-readable claim is made here.

Power-On / Power-Off Sequence

Follow the source sequence for VCC, RESET, STBYB, LVDS and backlight. The diagram lists a restart interval of at least 2 seconds.

The source lifetime table and its notes use different current conditions. No lifetime claim is made until these are reconciled. The source specifies a 12S4P, 48-LED circuit and recommends constant-current drive. Review the full backlight thermal/current requirements before integration.
