Abstract

The invention discloses an embedded touch display panel and a preparation technology thereof. The embedded touch display panel sequentially comprises a TFT (thin film transistor) substrate, a liquid crystal layer, a color filter, a polarizer and a glass cover plate, wherein the polarizer is a non-conductive polarizer, a transparent conductive layer is arranged between the polarizer and the color filter, a ground pin is also arranged on the TFT substrate, and the transparent conductive layer is electrically connected with the ground pin on the TFT substrate. The transparent conductive layer and the non-conductive polarizer are adopted to replace a high-impedance-state polarizer in the embedded touch display panel, and the production cost is greatly reduced; the partial attachment method of the frame-attached non-conductive polarizer is adopted, so that the bubble problem caused by full-attached polarizers is effectively solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an in-cell touch display panel and a preparation process thereof. Background technique [0002] In the prior art, the touch display panel includes an on-cell touch display panel (OnCellTouch) and an in-cell touch display panel (InCellTouch). [0003] The on-cell touch display panel (OnCellTouch) refers to the touch panel installed outside the display panel, including resistive and capacitive touch panels, which are usually manufactured by other touch panel manufacturers, and then connected with the display panel. Panels are pasted and assembled. [0004] The in-cell touch display panel (InCellTouch) integrates touch components into the display panel, so that the display panel itself has a touch function, so there is no need for additional lamination or assembly processes with the touch panel, so that Technologies are usually developed by TFTLCD panel makers.
