    • A touch panel display configured to improve touch panel detection for sensor panels embedded in display modules. Touch panel detection can be improved by arranging an optically anisotropic cover over a display module within which an optical sensor panel is embedded. Since the optically anisotropic cover comprises light-guiding channels through which light is guided by total internal reflection, the cover can effectively shift the sensor plane from an outer surface of the cover, near the location of an object to be detected, to an inner surface of the cover, near the location of the sensor panel. In additional, the optically anisotropic cover can effectively shift the image plane from the inner surface of the cover, near the display module, to the outer surface of the cover, near the viewing surface.
    • 触摸面板显示器被配置为改进嵌入在显示模块中的传感器面板的触摸面板检测。 可以通过在嵌入光学传感器面板的显示模块上布置光学各向异性覆盖层来改善触摸面板检测。 由于光学各向异性覆盖物包括导光通道,通过该导光通道光被全内反射引导,所以盖可以有效地将传感器平面从待检测物体的位置附近的盖的外表面移动到内表面 的盖子,靠近传感器面板的位置。 此外,光学各向异性覆盖物可以有效地将图像平面从显示模块附近的盖的内表面移动到靠近观察表面的盖的外表面。
