    • A touch screen system includes an in-cell type optical touch device for displaying images and receiving a light signal, an out-cell type touch device for sensing a finger or a non-optical stylus, a first functional unit connected with the in-cell type optical touch device, a second functional unit connected with the out-cell type touch panel and a third functional unit connected with the first functional unit and the second functional unit. The out-cell type touch device is disposed on the in-cell type optical touch device. The first functional unit converts an analog sensing signal received by the in-cell type optical touch device into a first electrical signal. An object-sensing signal generated from the out-cell type touch panel is processed by the second functional unit to generate a second electrical signal. The third functional unit analyzes the first electrical signal and the second electrical signal and generates valid output signals.
    • 触摸屏系统包括用于显示图像和接收光信号的小区内型光学触摸装置,用于感测手指或非光学触控笔的外部小区类型的触摸装置,与信元内连接的第一功能单元 与小区型触摸面板连接的第二功能单元和与第一功能单元和第二功能单元连接的第三功能单元。 外部小区型触摸装置设置在小区型光学触摸装置中。 第一功能单元将由单元内型光学触摸装置接收的模拟感测信号转换为第一电信号。 从小区外触摸面板产生的对象感测信号由第二功能单元处理以产生第二电信号。 第三功能单元分析第一电信号和第二电信号并产生有效的输出信号。
