Description
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. G+G+LCD structure, etched AG surface and 6H hardness. ILI2511 controller; USB / I2C touch interfaces. Outline dimensions: 294.4 × 178.5 × 14.25 mm, excluding PCBA. View the full-size drawing. 50-pin FPC connector: AORORA F31L-1A7H1-21050 or BJD 101049-205050, as named in the source. NTC: Murata NCU15XH103F6SRC. These are source-listed limits, not nominal supply settings. The horizontal-display timing is for two-port LVDS; it does not change the 1920 × 1080 panel resolution. 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. “—” means not specified; TBD values remain unresolved. Source measurement guidance specifies 30-minute stabilization and 30-minute backlight warm-up in a windless room. White uniformity is minimum divided by maximum luminance across nine points, multiplied by 100%. These are specification test conditions, not independent certification or proof of completed qualification. The source requires no surface condensation during testing, a maximum display-surface temperature of 85°C and at least 24 hours of recovery at room temperature before cosmetic/function inspection. Confirm the preliminary specification revision, brightness discrepancy, backlight current/lifetime conditions, mechanical fit and host LVDS compatibility before sample approval. Supply the model number, required quantity, host details and enclosure drawing when making an inquiry.12.8-Inch Optical Bonded Capacitive Touch Display
