What is the resistive film Character LCD Module method resistive touch panel technology

Resistive film type touch panel technology with the 40-year-old the oldest, is also one of the main. In the touch panel GongHuoE in 2009, the resistive film about half way. The number of vendors in the world, more than 50.TFT LCD Misplays
The basic structure of the resistive film, forming a transparent conductive film on a glass substrate, the spacer clamped thereon, and then set the transparent conductive thin film. The electric field is applied on the transparent conductive thin film of the upper side and the lower side of the glass substrate in the vertical direction, respectively. Touch an arbitrary position on the side of the transparent conductive thin film, the transparent conductive film on the glass substrate and the lower side portion will be short-circuited. Touch position is calculated by measuring the voltage decline. Recently, for the realization of thin film substrate in place of the lower side of the glass substrate; improve the durability of the glass substrate with a transparent conductive film instead of on the side of the transparent conductive film began to appear. In addition, the embodiment of the antiglare (AG) and antireflection surface treatment has also emerged. The resistive film becomes large in size, the accuracy and the yield will fall. Therefore, the current size of about 2 to 26 inches. Uses, and more for mobile products and POS terminals.
The resistive film method is considered in a long period of time can not support more than two fingers simultaneously touch on the screen to operate the multi-point touch. However, to achieve multi-touch resistive film type touch panel has been published. Multi-touch resistive film is France Stantum. The company uses digital resistive film (also known as matrix resistive film method) instead of the regular analog resistive film, developed a multi-touch detection technology alone. The electrode structure of the type with ordinary analog resistive film method. Using a linear mapping of the resistive film, rather than the entire surface of the uniformly distributed resistive film. Up and down along the cross direction relative to the formation of a touch panel. Currently, the company is developing to support more than 10 points at the same time the digital input resistance film type touch panel.TFT LCD Module
