近年来，随着操作人性化、简洁化的发展趋势，带有触控面板的触控显示设备被越来越广泛地应用于生活中。由于用户可以通过直接用手或者其他物体接触触控面板的方式输入讯号，从而减少甚至消除用户对其他输入设备(如键盘、鼠标、遥控器等)的依赖，使用户操作的便利性大幅提升。In recent years, with the development trend of humanized and simplified operation, touch display devices with touch panels are more and more widely used in daily life. Since users can input signals by directly touching the touch panel with their hands or other objects, the user's dependence on other input devices (such as keyboard, mouse, remote control, etc.) is reduced or even eliminated, and the convenience of user operation is greatly improved.
一般触控面板的触控单元包括一感应电极数组，其具有沿垂直、水平方向排列的复数感应电极串行、用以电性连接感应电极的桥接金属、以及位于其间的绝缘层。触控面板上需要设置保护玻璃(coverglass)以保护触控面板，利用黏着剂取代传统手机屏幕贴边框的方式，将保护玻璃与触控面板全面性贴合，能够有效改善因贴边框形成的空气层而影响触控面板的显示质量。现今常见的黏着剂如：光学胶层(OpticalClearAdhesive,OCA)、光学树脂层(opticalClearresin,OCR)等。A touch unit of a general touch panel includes a sensing electrode array, which has a plurality of sensing electrode series arranged in vertical and horizontal directions, bridging metals for electrically connecting the sensing electrodes, and an insulating layer therebetween. The touch panel needs to be equipped with a cover glass to protect the touch panel. Using an adhesive instead of the traditional mobile phone screen frame, the cover glass and the touch panel are fully bonded, which can effectively improve the atmosphere caused by the frame. layer and affect the display quality of the touch panel. Common adhesives such as: Optical Clear Adhesive (OCA), Optical Clear Resin (OCR), etc.
然而，虽然黏着剂可改善触控面板的显示质量，却使触控面板的电极数组图案容易被人眼察觉，造成可视性问题。由此，目前亟需发展一种触控显示设备，其能够降低电极图案的可视性问题，以提升使用者观看触控显示设备的视觉质量。However, although the adhesive can improve the display quality of the touch panel, it makes the electrode array pattern of the touch panel easy to be perceived by human eyes, causing visibility problems. Therefore, there is an urgent need to develop a touch display device, which can reduce the visibility problem of the electrode pattern, so as to improve the visual quality of the user watching the touch display device.
发明内容Contents of the invention
