Description
Product Introduction
The CTPH050A11 is a professional-grade 5.0-inch LCD Touch Panel component specifically engineered for high-resolution TFT-LCD and IPS displays. This product adopts a rugged Glass+Glass dual-glass architecture with a total thickness of 2.0±0.2mm, delivering excellent optical transmittance (≥85%) and a surface hardness of up to 6H, ensuring superior visual clarity and scratch/s abrasion resistance. The panel is powered by a high-performance GT911 driver IC and supports IIC communication interface.
In terms of electrical and physical characteristics, its operating voltage is 3.0V±0.3V, with lens dimensions of 133.00×68.50mm and a view area of 110.10×62.05mm, supporting 480×854 resolution coordinate positioning. To guarantee stability in industrial-grade applications, this LCD Touch Panel operates reliably from -20°C to 70°C and can be stored from -30°C to 80°C (humidity ≤90% RH). The backside is reinforced with a steel plate for grounding and pre-laminated with 3M high-performance double-sided tape, making it ideal for smart handheld terminals, industrial control panels, automotive displays, and other reliability-critical scenarios.
Product Highlights of LCD Touch Panel
- Rugged G+G Dual-Glass Architecture with 6H Surface Hardness
Designed for demanding industrial and commercial environments, this 5.0-inch LCD Touch Panel rejects the easily deformable and yellowing G+F construction in favor of a robust G+G full-bonded structure. The top protective glass achieves a surface hardness of up to 6H, effectively resisting scratches, abrasion, and impact from daily use, ensuring that end devices remain intact after years of high-frequency operation. - ≥85% High Transmittance for True-Color Visual Experience
In outdoor or bright-light conditions, display visibility is paramount. This capacitive touch screen features high optical transmittance of ≥85%, significantly minimizing light reflection and scattering among multiple layers. This allows the underlying 480×854 resolution LCD display to fully preserve its native color saturation, high contrast, and backlight brightness, delivering a crisp and clear interactive visual experience. - Built-in GT911 Industrial-Grade Capacitive Touch Controller
At the core of this LCD Touch Panel is the high-performance GT911 driver IC, which integrates 26 drive channels and 14 sense channels. With a native touch scanning frequency of up to 100Hz, automatic temperature drift compensation, and robust EMI filtering algorithms, the GT911 precisely captures minute capacitance changes. This ensures smooth, zero-latency, drift-free 5-point touch operation even in electrically noisy factory floors or equipment interiors. - Wide Operating Temperature Range for Extreme Environments
To meet the stringent selection criteria for automotive, power, and outdoor terminals, this LCD Touch Panel offers exceptional weather resistance and stable operation under wide temperature fluctuations, with an operating temperature range of -20°C to +70°C (relative humidity ≤90% RH) and a storage temperature range of -30°C to +80°C (relative humidity ≤90% RH).
Core Application Fields
With its compact 5.0-inch form factor and industrial-grade reliability, this LCD Touch Panel is widely adopted across the following vertical industries:
- Industrial Automation and HMI Control Panels: CNC machines, programmable logic controller terminals, smart power meters, and other applications requiring dustproof, moisture-proof, and shock-resistant performance.
- Smart Home Ecosystems and Building Intercoms: High-end smart wall switches, smart home central gateways, access control security panels, and video doorbells.
- Medical Devices and Biochemical Testing Instruments: Portable patient monitors, smart infusion pump control screens, and laboratory testing equipment. The flat G+G glass surface is easy to clean and compatible with frequent wiping using isopropyl alcohol or medical-grade disinfectants.
- Intelligent Transportation and Automotive Displays: Smart dashboards for two-wheel electric vehicles, EV charger HMI, OBD-II diagnostic systems, and marine electronic instruments operating in wide-temperature environments.
- Warehouse Logistics and Handheld Terminals: Logistics PDAs, rugged tablets, mobile retail POS machines, and other handheld devices subject to high-frequency use and frequent drops or impacts.
Technical FAQ of LCD Touch Panel
Q1: How are the pins defined on this 5.0-inch LCD touch screen panel?
A: The CTPH050A11 connects to the main control board via a 6-pin FPC flexible tail cable with a 0.5mm pitch. The precise hardware pin symbol definitions from Pin 1 to Pin 6 are as follows:
- VDD: Core power input pin
- INT: Interrupt output pin (sends a low-level interrupt signal to the host MCU/CPU upon touch event detection)
- GND: System ground
- SDA: I2C serial data line
- SCL: I2C serial clock line
- RTN / RESET: Hardware reset pin (active low, used to initialize the GT911 chip)
Q2: What are the key advantages of the G+G dual-glass structure over G+F architecture for an LCD Touch Panel?
A: The G+G architecture offers significantly superior structural rigidity and optical quality compared to G+F. A G+G panel consistently maintains high transmittance of ≥85% and does not cause water-wave distortions or color shifts on the underlying display even under localized heavy finger pressure. Moreover, in the wide-temperature environments (-20°C to +70°C) typical of industrial and automotive applications, the G+G structure resists bubble formation, warping, or touch failure caused by thermal expansion and contraction.
Q3: What bonding method is recommended for assembling this CTP touch panel with a 5.0-inch LCD display?
A: This LCD Touch Panel supports both conventional air bonding and premium optical bonding. For cost-sensitive indoor devices, perimeter double-sided tape may be used. However, for outdoor high-brightness, high-glare, or automotive scenarios, we strongly recommend full lamination using OCA or LOCA optical adhesive. Full lamination completely eliminates the air gap between glass layers, removes internal reflections, dramatically improves sunlight readability, and significantly enhances the overall module’s shock resistance and drop protection capabilities.
