7 inch capacitive touch panel HCT1829GG070A1-V0 features Glass-Glass (G+G) structure with 2.0 mm cover lens, glass touch sensor, and ILI2511 touch controller. Designed as standalone touch component, this 7 inch touch panel uses USB interface for integration with compatible host systems. Its black silk-printed cover glass and flexible printed circuit (FPC) support installation in industrial and commercial equipment. Mechanical fit, USB controller compatibility, and any subsequent bonding to separately selected LCD module should be evaluated during product integration.

Combining glass-based touch structure, integrated controller, and USB connection for mechanical and electrical integration into OEM equipment.
Glass+Glass Touch Structure
The G+G construction combines 2.0 mm glass cover lens with 0.70 mm glass touch sensor, joined by 0.20 mm SCA layer. The panel features black border printing, light transmittance of at least 86%, and cover hardness of at least 6H. These specifications provide defined optical and mechanical characteristics for equipment integration.
ILI2511 USB Touch Controller
The integrated ILI2511 controller provides the touch-processing solution for this 7 inch USB touch panel. 4-pin USB connection carries power and differential data signals between the controller and the host system. USB compatibility, driver requirements, touch-point configuration, and application behavior should be verified against the intended operating system and hardware platform.
FPC & Mechanical Integration
The touch panel features 164.66×99.76 mm cover lens, with separate touch sensor and FPC connection arrangement. Its dimensional drawing supports evaluation of bezel clearance, connector placement, and assembly tolerances. MAXEN can review mounting and interface requirements for integration into new OEM equipment or compatible existing designs.

FAQs
Q
1. How is the USB touch panel connected to a host system?

1. How is the USB touch panel connected to a host system?
The controller provides 4-pin USB connection with VDD, D−, D+, and GND signals. Before integration, the host's USB interface, controller supply requirements, connector arrangement, operating system, and driver support should be checked. A functional sample test is recommended to confirm touch recognition and coordinate mapping on the intended hardware platform.
Q
2. How is compatibility with an existing 7 inch LCD verified?
▼
2. How is compatibility with an existing 7 inch LCD verified?
Compatibility is evaluated from the cover lens dimensions, viewing area, sensor outline, FPC position, bezel clearance, and the chosen bonding or mounting method. LCD panel size alone is not sufficient to confirm fit. Customers should provide the LCD mechanical drawing and assembly requirements so that MAXEN can review the proposed integration before sample approval.
Q
3. Are multi-touch and glove operation supported?
▼
3. Are multi-touch and glove operation supported?
The provided drawing identifies the ILI2511 controller but does not state the supported touch-point count or verified glove-touch conditions. These functions should not be assumed from the controller name alone. MAXEN can evaluate the target operating mode using the selected sensor configuration, controller firmware, cover glass, and customer application requirements.
Q
4. What are the MOQ, lead time, and sample requirements?
▼
4. What are the MOQ, lead time, and sample requirements?
MOQ and production lead time depend on whether the order uses the existing design or requires customized cover glass, FPC, tooling, or controller configuration. Customers can share the expected annual quantity, host-system information, and mechanical drawings for quotation. Sample evaluation should cover electrical connection, touch performance, and mechanical assembly before production approval.
Q
5. Which cover glass and FPC features can be customized?
▼
5. Which cover glass and FPC features can be customized?
For OEM projects, MAXEN can review requests involving cover glass outline, black border artwork, FPC routing, and connector placement. Changes to the glass stack, electrical configuration, or surface treatments require separate engineering evaluation and may affect tooling, sampling, and lead time.
