背景技术Background technique
现代消费性电子装置多配备触摸板做为其输入设备之一。触摸板根据感测原理的不同可分为电阻式、电容式、音波式及光学式等多种形式。Modern consumer electronic devices are often equipped with touch pads as one of their input devices. Touch panels can be divided into resistive, capacitive, acoustic and optical types according to different sensing principles.
触控面板的技术原理是当手指或其他介质接触到屏幕时,依据不同感应方式,侦测电压、电流、声波或红外线等,以此测出触摸点的坐标位置。例如电阻式即为利用上、下电极之间的电位差,计算施压点位置,以检测出触摸点所在。电容式触控面板是利用排列的透明电极与人体之间的静电结合所产生的电容变化,从所产生的电流或电压来检测其坐标。The technical principle of the touch panel is that when a finger or other medium touches the screen, it detects voltage, current, sound waves or infrared rays according to different sensing methods, so as to measure the coordinate position of the touch point. For example, the resistive type uses the potential difference between the upper and lower electrodes to calculate the position of the pressure point to detect the location of the touch point. The capacitive touch panel uses the capacitance change generated by the electrostatic combination between the arranged transparent electrodes and the human body, and detects its coordinates from the generated current or voltage.
随着智能型手机的普及化,多点触控的技术需求与日俱增。目前,多点触控主要是通过投射电容式(Projected Capacitive)触控技术来实现。With the popularization of smart phones, the demand for multi-touch technology is increasing day by day. At present, multi-touch is mainly realized through projected capacitive (Projected Capacitive) touch technology.
投射电容式技术主要是通过双层氧化铟锡材质(Indium Tin Oxide,ITO)形成行列交错感测单元矩阵,以侦测得到精确的触控位置。投射电容式触控技术的基本原理是以电容感应为主,利用设计多个蚀刻后的氧化铟锡材质电极,增加数组存在不同平面、同时又相互垂直的透明导线,形成类似X、Y轴驱动线。这些导线皆由控制器所控制,其是依序扫瞄侦测电容值变化馈送至控制器。The projected capacitive technology mainly uses a double-layer Indium Tin Oxide (ITO) material to form a row-column interlaced sensing unit matrix to detect precise touch positions. The basic principle of projected capacitive touch technology is based on capacitive sensing. By designing multiple etched indium tin oxide electrodes, an array of transparent wires with different planes and perpendicular to each other is added to form a drive similar to X and Y axes. Wire. These wires are all controlled by the controller, which scans sequentially to detect changes in capacitance values and feeds them to the controller.

The sensing conductor lines 110 , 120 on the known organic light emitting diode display touch panel structure 100 are arranged along a first direction (Y) and a second direction (X). When the sensing conductor line 120 performs touch sensing and transmits the sensed signal to the control circuit 131 on a flexible circuit board 130, it needs to be connected to the flexible circuit through the side wiring 150 of the panel 140. plate 130. Such a design will increase the width of the frame of the touch panel, which is not suitable for the trend of narrow frame design. Therefore, there is still room for improvement in the known organic light emitting diode display touch structure.
