What are the advantages and disadvantages of touch screen sensors?

As a professional manufacturer in the touch screen industry, Shenzhen Xinlilai Touch Technology Co., Ltd. is well aware that there is no perfect functional chip, only the most suitable solution for specific application scenarios. Let's objectively analyze the advantages and disadvantages of mainstream feature films to help you make wiser choices.
 

Traditional ITO functional sheet: a mature and stable choice
Indium tin oxide (ITO) functional sheets are currently the most widely used solution. Its advantages lie in mature technology, high light transmittance (up to 90% or more), and high degree of process standardization. Our ITO functional sheet has undergone special treatment, with a surface hardness of up to 7H, which can effectively resist daily scratches. In addition, ITO functional sheets also have inherent limitations: they are brittle and not suitable for flexible applications; When used on a large scale, the resistance value is relatively high, which may affect touch sensitivity; However, as a rare metal, indium poses certain supply chain risks.
Metal mesh functional sheet: the preferred choice for large-sized applications
 

For medium to large-sized touch devices, metal mesh functional sheets exhibit unique advantages. The grid structure composed of ultra-fine copper wires allows its square resistance to be as low as 15 Ω/□, making it particularly suitable for interactive whiteboards or digital signs over 86 inches. In actual testing, our metal mesh functional sheet can maintain stable performance in environments ranging from -20 ℃ to 85 ℃. However, such functional chips may produce Moir é fringes at specific angles, which have a slight impact on the display effect and need to be optimized through special grid design.
 

Hybrid functional film: an innovative solution for balancing performance
We have developed various hybrid functional films for specific application scenarios. For example, in the automotive field, combining ITO with metal grids not only ensures high transparency but also enhances stability in complex electromagnetic environments. The medical device specific functional sheet has added antibacterial coating, which meets both touch accuracy and hygiene requirements. Although these customized solutions have a high unit price, they can bring significant differentiated competitive advantages to end products.
 

Choice suggestion: What is suitable is the best
When selecting feature films, it is recommended to consider four dimensions: 1) device type and usage environment; 2) Touch performance requirements; 3) Display effect requirements; 4) Cost control objectives.
