Our engineering research has developed a touch screen I2C into USB compatible software, convenient I2C and USB conversion, in the design and debugging can be fast detection.

An LCD consists of two polarizing filters that are perpendicular to each other, so under normal circumstances, all light trying to penetrate should be blocked. But because of the deformation of the liquid crystal between the two filters, the light is altered 90 degrees by the liquid crystal molecules after passing through the first filter and eventually through the second filter.

"Optical lamination technology of LCD touch screen is the future trend. Optical lamination is to completely fit the panel and touch screen together in a seamless way. There is no air layer between the display layer and the touch layer, and dust isolation reduces the reflection between the display panel and the glass. The lamination technology makes the whole LCD more thin, the display looks more t
