5.5-inch OGS Structure Projected Capacitive Touch Panel for Smart Electronic Equipment
Fill out my online form.
Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.
Greg: Hello, Dr Pan. I am Greg. There are so many structures for projected capacitive touch screen. May I ask what OGS structure is?
Dr Pan: Hello, Greg. OGS means one glass solution.
Dr Pan: It is going to need one glass to achieve the touch function.
Dr Pan: Let us look at the structure “One-sheet two-ITO laminated structure”.
Dr Pan: From top to bottom, Cover glass, ITO1 and ITO2.
Dr Pan: Advantage: thinnest, high transmittance, multi-touch, good at hand writing.
Dr Pan: Disadvantage: low reliability, low strength, low anti ESD, high cost, only suitable for the sizes less than 15 inch.
Greg: Dr Pan, after learning so many structures of capacitive touch screen, do you think OGS is the future?
Dr Pan: Maybe. It is very thin, light, and high light transmittance because it only has one glass.
Dr Pan: But it has been so many years since OGS technology has been invented, we are still unable to solve the problems of low strength and low anti-interference.
Dr Pan: There is no evidence that the problems can be solved anytime soon unless there are major innovations in the glass industry.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
