Abstract

The invention discloses a resistor array touch screen. The touch screen body includes a detecting layer, a working layer, and a transparent insulation point layer between the detecting layer and the working layer. The detecting layer includes a transparent conductive film detecting layer, including a plurality of detecting units, wherein these detecting units are mutual independent and insulated, and each detecting unit forms a detecting electrode for determining touch points. The working layer includes a transparent conductive film resistor working layer matching with the detecting electrodes, and the transparent conductive film resistor working layer forms a resistor working unit. The invention realizes resistor array touch screen multi-point touching by different locating areas of different points in the resistor array touch screen multi-point touching determined by the different detecting electrodes, and supports single-point touch or multi-point touch concerning two or more points. The precise positions of detecting touch points in the detecting electrode area are detected by specific resistor characteristic signal detected by the detecting electrodes where the touch points locate, therefore the invention has precise positioning characteristic like common resistor touch screens.

Description

technical field [0001] The invention relates to a touch screen, in particular to a resistance array touch screen capable of supporting single point or multi-point touch of more than two points. Background technique [0002] Existing touch screens generally include a touch panel, a controller and a software driver. Touch panels are transparent panels with a touch-sensitive surface. The touch panel is located on the front of the display so that the touch-sensitive surface covers the viewable area of ​​the display. The touch panel records touch events and sends touch signals to the controller. The controller processes these signals and sends the data to the computer system. A software driver translates touch events into computer events. [0003] Several touch screen technologies are known, including: resistive, capacitive, infrared, surface acoustic wave, electromagnetic, near-field imaging, and others. Consider the advantages and disadvantages of each device when designin...
