第一电极22和第二电极52相对设置形成电容式触控面板100，满足触控要求，金属材料制成的第一电极22和第二电极52易弯折，适用于柔性显示设备，且材料阻抗低，第一电极22与第一引脚24、第二电极52与第二引脚54可以在同一道制程中图案化完成，减少制程，节约生产成本。
请参阅图19，本发明实施例还提供一种显示设备200，包括显示面板300和本发明实施例提供的触控面板100，触控面板100固定于显示面板300的显示面302一侧，用于接收用户的触控。一种实施方式中，显示设备200为柔性显示设备200，显示面板300及触控面板100均具有柔性可弯折。显示面板300可以为有源矩阵有机发光二极体(Active-matrix organic light emitting diode，AMOLED)显示面板300，显示设备200包括手机、电视、显示器、平板电脑等。
第一电极22和第二电极52相对设置形成电容式触控面板100，满足触控要求，金属材料制成的第一电极22和第二电极52易弯折，适用于柔性显示设备200，且材料阻抗低，第一电极22与第一引脚24、第二电极52与第二引脚54可以在同一道制程中图案化完成，减少制程，节约生产成本。
以上所揭露的仅为本发明几种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
