In the field of touch screens, glass and PMMA materials each have their own unique advantages, the specific choice of which material depends on the specific application needs of the touch screen and budget.
Advantages of glass material:
1. Touch sensitivity and optical transparency:
The surface of glass is smoother and less uneven, which contributes to the smoothness and stability of the fingertip when sliding on the touch screen.
With better optical transparency, glass can more accurately transmit touch signals and provide a clear, accurate display.
2. Hardness and abrasion resistance:
Glass is harder, more wear-resistant and less prone to scratches than acrylic, and can better resist the wear and tear caused by daily use.
High hardness glass materials such as Corning glass, its hardness can reach 8H ~ 9H, more to meet the needs of high durability.
3. Chemical and heat resistance:
Glass is an inorganic material that is not susceptible to chemical corrosion or ultraviolet light from sunlight, and will not yellow or be affected by chemicals over time.
Glass has high thermal stability and will not be deformed by high temperatures and other problems.
4. Environmental friendliness:
Glass is a natural material that can be reused through recycling and is highly environmentally friendly.
Advantages of PMMA material:
1. Impact resistance:
Acrylic panels are many times better than glass in terms of impact resistance, with little risk of fracture, making them more suitable for application scenarios that require a certain level of impact.
2. light weight:
The same size and thickness, PMMA is lighter than glass, easy to install and carry.
3. Processing efficiency and cost:
PMMA cover are more efficient in the processing, and the production cost is relatively low, suitable for mass production and application.
4. Transparency:
PMMA has excellent transparency, although it may not be as high as glass, but in some application scenarios is sufficient to meet the needs.
Comprehensive comparison and selection recommendations:
1. Durability and clarity: If the touch screen needs to withstand frequent touch and slide, and the image quality and clarity of the high requirements, it is recommended to choose glass.
2. Lightweight and cost: If the touch screen needs to be lightweight and low cost, and the durability and clarity requirements are not particularly high, you can choose PMMA material.
3. Specific application scenarios: in the need to withstand a certain degree of impact or special chemical environment of the scene, the acrylic material may be more suitable. In the need for high light transmission, high clarity, high durability of the scene, the glass material is more advantageous.
In summary, whether the touch screen is made of glass or PMMA is good, depending on the specific application requirements and budget. When choosing, touch sensitivity, hardness and abrasion resistance, chemical and heat resistance, self-weight and cost should be considered in order to make the most suitable choice.
