5 Advantages Of G+G And G+P Capacitance Touch Display for Mac

The realm of computing has witnessed a significant transformation with the integration of touch screen technology, especially within the ecosystem of Apple’s macOS devices. This evolution not only signifies a shift in user interaction but also marks a technological leap in how we envision and utilize our computers. Here, we delve into the intricate world of touch display for mac, focusing on their structure, technological underpinnings, and the profound impact they have on Mac users.

Understanding the Fundamentals of Touch Screen Technology

Touch screens have become an integral part of modern computing, offering a more intuitive and interactive way to engage with digital content. The technology behind these screens, particularly in high-end devices like Macs, predominantly involves capacitive touch sensing:

• Capacitive Touch Screens: These work by sensing the electrical charge from your body when you touch the screen. This technology requires a conductive material like your finger to interact with the screen’s electric field. Capacitive touch screens can be further categorized based on their construction:
  • G+G (Glass + Glass): This is the most prevalent in premium devices, including the latest touch-enabled Macs. It involves a tempered glass cover bonded to a sensor glass layer. This structure provides:
    • Durability: The top layer of tempered glass has a hardness rating of 6H-7H, making it resistant to scratches and daily wear. This is particularly beneficial for devices like Macs, which might be used in various settings, from professional studios to rugged environments.
    • Corrosion Resistance: Unlike plastic covers, glass does not react to substances like oils, acids, or sunlight, ensuring the screen remains clear and functional even in challenging conditions.
    • High Light Transmittance: Glass allows up to 91% light to pass through, offering crystal-clear visuals which are crucial for graphic designers, video editors, and users requiring accurate color representation.
    • Smooth Interaction: The glass-on-glass construction provides a smooth, frictionless surface for touch, enhancing the user experience in navigation, drawing, or any touch-based interaction.
  • G+F (Glass + Film): This structure uses a thin film as the upper layer, which can offer flexibility and a lower cost but at the expense of some durability and visual clarity.
  • G+P (Glass + Plastic): Here, the touch sensor is paired with a plastic cover. While this is less common in high-end devices due to its susceptibility to scratches and lower light transmittance, it’s often used in more budget-friendly or flexible applications.

The Advantages Of G+G And G+P capacitative touch screen:

1) Hard And Wear-resistant

The surface cover of the G+G capacitative touch screen is tempered glass. Its surface is very hard, the hardness can reach 6H- 7H. As long as you don’t need to grind super-hard objects. Such as quartz, emery paper. Generally, you don’t have to worry about scratches.

The disadvantage is that the processing technology is difficult and the cost is high.

However, the surface of the G+P capacitive screen is PET plastic. The hardness is usually only 2~3H, which is quite soft.

Moreover,it is very easy to produce scratches in daily use.So you can add a film and carefully protect it. Its advantages are The process is simple and the cost is low.

2) Corrosion Resistance

The surface of the G+P capacitative touch screen is plastic. So it is easy to harden, become brittle, and change color under the action of acid, alkali, oily substances and sunlight. Therefore, you must use it carefully to avoid contact with these substances. If improper use, it will produce aerosol and leukoplakia.

The tempered glass surface of the G+G capacitative touch screen is very resistant to corrosion. It is not afraid of similar substances at all. And strong acid and alkali are not good. You can use it with confidence and boldness anywhere, especially when you are eating and operating. it is inevitable that your fingers Will not be stained with grease.

The corrosion resistance of the G+G capacitive screen is extremely obvious.

3) High Light Transmittance

We not only use the capacitance touch screen for operation, but more importantly, for viewing and appreciating the screen content.

The light transmittance of the G+G glass capacitance touch screen is as high as 91%. It has little effect on the screen picture. While the G+P PET cover is transparent. The light rate is only 83%, the light loss is serious. The picture is inevitably low and dim.

However, the light transmittance of the PET cover will gradually decrease over time. It is also a fatal flaw of the G+P capacitance touch screen.

4) The Control Feels Smooth

The glass screen of G+G is very smooth. And the touch of fingers is like clouds and water. Moreover, the control feels very smooth. While G+P’s PET plastic is a polymer material with great surface damping force. So the sliding feel is jerky and not smooth. It is very influential operating experience.

5) High Reliability

The cover plate of G+G capacitive screen and sensor glass are glued using advanced optical glue and vacuumed. It has a very high service life and adhesion.

G+P capacitive screen uses PET’s own chemical glue for bonding . The process is very simple. But the bonding reliability is not high. There is also a very important point. the thermal expansion coefficient of the thermal expansion .

And contraction of the G+P capacitive screen sensor glass and the PET plastic cover is huge. However, at high or low temperatures, the G+P capacitive screen will be prone to the difference in the expansion coefficient. And cracked, thus scrapped!

The Evolution of Touch in Macs

Apple’s foray into touch-enabled devices began with the iPhone and iPad, leveraging the G+G structure for its benefits. Here’s how touch has transformed Macs:

1. Integration into macOS: Recent updates to macOS have introduced touch capabilities in some models, providing users with an entirely new dimension of interaction:
   • Enhanced Creativity: Artists and designers benefit from direct touch control, which can simulate the feel of traditional media with digital precision.
   • Streamlined Operations: Simple gestures for navigation, zooming, and scrolling make the user experience more fluid, reducing the reliance on physical inputs like mouse or trackpad.
   • Touch Bar: While not a full touch screen, the Touch Bar in MacBook Pros offers context-sensitive controls, showing how Apple is integrating touch into their computing ecosystem gradually.
2. Challenges and Innovations:
   • Adapting Software: Touch functionality requires software to be optimized for touch input, which involves rethinking user interfaces and interaction models.
   • Balancing Traditional Use: Apple has had to ensure that the touch functionality doesn’t detract from the traditional Mac experience, which has always emphasized precision through peripherals like the mouse and keyboard.
3. Future Prospects:
   • Foldable Displays: Apple’s patents suggest interest in foldable screens, which could bring touch functionality to larger Mac devices, offering the benefits of both portability and expansive screen real estate.
   • Haptic Feedback: Enhancing touch screens with haptic feedback could provide tactile feedback, simulating physical buttons or textures, thus bridging the gap between touch and traditional input methods.

Detailed Analysis of G+G in Macs

The G+G structure in touch-enabled Macs offers several advantages:

• Optical Quality: With high light transmittance, Macs provide vivid and accurate displays, essential for professional-grade work.
• Reliability: The use of optical glue ensures a robust bond between the glass layers, minimizing the risk of delamination over time.
• Sensitivity and Precision: The G+G structure allows for high touch sensitivity, crucial for fine motor tasks like drawing or editing.
