本发明涉及显示领域，特别涉及一种触控结构及显示面板。
背景技术
由于有智能驾驶、智能家电、便携式终端等方面的需求，柔性显示屏在近年来的各大展会上备受关注，被认为是未来显示器的重要发展方向。
液晶显示屏或是OLED显示屏由于其轻、薄、显示效果好等优点，已被广泛应用并被市场普遍接受。但市场对于显示屏的轻薄要求却是在不断提高。近年来，由其是手机制造商对整机厚度减薄的持续需求，使得其对手机屏幕(TFTLCD\OLED)的厚度持续要求减薄。这其中偏光片作为屏幕构成的主要结构之一，对偏光片的本体厚度的要求也是希望其能在保持正常功能的同时，能够越来越薄，从而减薄屏幕的整体厚度。
对此，业界不断研发，将偏光板的厚度从最初的单偏200μm左右，通过TAC及PVA结构减薄，将其整体厚度逐渐降到100μm。之后，各偏光板供应商开始探索通过将TAC更换为更薄的COP材料以进一步的降低厚度。更有甚者，通过减少TAC层来实现将其整体厚度降低到80μm左右。考虑到支持强度收缩及信赖性等问题，减少TAC层的偏光片POL多使用在带增反膜的下偏光板中，这样可以将上、下偏光板的整体厚度降到160um左右。
