1. G+F process structure of capacitive screen
The capacitive screen of G+F structure has the first layer of tempered glass on the surface, and then a layer of FILM film material. That is, glass cover + OCA + Film Sensor. Glass cover: plays the role of protecting the screen and optimizing the surface texture. Generally, tempered glass with high strength, hardness and good light transmittance is selected. OCA: is a solid optical glue with good viscosity and high light transmittance. It is used for the bonding between the glass cover and the Film Sensor. Film Senser: The Senser made of FILM film material is the signal function layer of the capacitive screen, which transmits touch signals and can realize the touch function. Scope of application of this structure: suitable for products below 3.5 inches, low-cost solution.
2. G+F+F process structure of capacitive screen
The capacitive screen with G+F+F process structure also has the first layer of tempered glass, but with two layers of film material. The difference from the G+F structure is that it has an extra layer of Film Sensor. G+F+F can achieve multi-touch, and the screen is thinner, but the cost is higher than G+F.
3. G+G process structure of capacitive screen
The capacitive screen with G+G process structure, namely GLASS+GLASS, has the first layer of tempered glass on the surface and another layer of glass material Senser. The biggest difference between it and the G+F structure is the use of glass material Senser. The characteristics of G+G capacitive screen: hard and wear-resistant, corrosion-resistant, high light transmittance, smooth control feel, and good reliability. Since the surface cover is tempered glass, its surface is very hard, with a hardness of more than 8H, and it is very good at preventing scratches.
4. G+P process structure of capacitive screen
The capacitive screen of G+P process structure has the first layer of tempered glass and a touch layer of PC material. The characteristics of G+P capacitive type: low cost and simple process. Disadvantages: not wear-resistant, not corrosion-resistant, poor light transmittance, slow control and poor reliability.
The above are the most common capacitive screen process structures on the market. In fact, each structure has its advantages and disadvantages. Users need to choose the appropriate capacitive screen product based on their own costs and application areas.
