Abstract
A touch display device, including a protective layer, a display module, a touch layer, a fingerprint sensor layer, a backlight, and a shading layer. The fingerprint sensor layer and the touch layer are stacked together in the display area of the display device. By integrating the fingerprint sensor layer and the touch layer, the fingerprint recognition function can be realized while implementing the touch display, which not only reduces the production process, reduces the production cost, but also reduces the overall thickness of the display device.
