Abstract

The invention discloses a tough cover plate, a manufacturing method thereof and a touch display device. The touch cover plate comprises a cover plate body, a functional key pattern and a key functional wire, and the functional key pattern and the key functional wire are arranged on the back side of the cover plate body and are connected. According to the tough cover plate, the manufacturing method thereof and the touch display device, the functional key pattern and the key functional wire are arranged on the back side of the cover plate body, the problem that an adopted virtual functional key occupies a display area is avoided, and accordingly the display area of a screen is enlarged. A flexible circuit board does not need to be arranged on the back side of the cover plate body, the thickness of a key area of the cover plate body is reduced, and accordingly the situation that space is reserved for the flexible circuit board on the structure is avoided.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a touch cover plate, a manufacturing method thereof, and a touch display device. Background technique [0002] The in-cell (INCELL) and external (ONCELL) structures integrate the touch function of the external touch screen, but this function integration is limited to the display area (AA area) of the liquid crystal display (Liquid Crystal Display, referred to as LCD). The key part of the external touch screen does not have an integrated touch function. [0003] At present, the function buttons of the embedded (INCELL) and external (ONCELL) display modules mainly include two forms: 1. The LCD display area is realized by virtual function buttons, and the cover (CoverGlass, referred to as CG) is not set Button; 2. Set up a flexible printed circuit (FPC for short) on the back of the button area of ​​the CG to realize the button function. [0004] However, the existing technical sol...
