The utility model provides a touch screen. The touch screen comprises a display area and a non-display area, wherein the display area is divided into N touch areas, and each touch area comprises a plurality of touch electrodes for touch recognition; a master controller and N touch ICs are arranged in the non-display area; the touch electrodes in the N touch areas are connected to N touch ICs respectively, and the N touch ICs are connected to a master controller; wherein each touch IC is used for detecting whether touch occurs in each touch area or not, calculating position coordinates and sending the position coordinates to the master controller when touch occurs, and the master controller is used for processing the position coordinates; a regional mode is adopted, an independent small-size touch IC and master controller combined mode is adopted, touch recognition of a large-size touch screen is achieved, on one hand, the number of channels can be guaranteed, recognition precision canbe guaranteed, and on the other hand, production cost can be reduced. 本实用新型提供了一种触摸屏，触摸屏包括显示区和非显示区；显示区划分为N个触摸区域，每个触摸区域内包括用于进行触摸识别的多个触控电极；非显示区内设置有总控制器和N个触控IC；N个触摸区域内的触控电极分别连接至N个触控IC，所述N个触控IC连接至总控制器；各个所述触控IC用于检测各个触摸区域内是否发生触摸，在发生触摸时计算位置坐标并发送至所述总控制器，所述总控制器用于对所述位置坐标进行处理；采用分区域的方式，分别采用独立的小尺寸触控IC和总控制器组合的方式，实现大尺寸触摸屏的触控识别，一方面能够保证通道数量，保证识别精度，另一方面能够降低生产成本。
