Problems solved by technology

Usually, the multi-layer ink is formed by a printing process, resulting in a high thickness of the ink layer, usually the thickness of each ink layer is about 8um to 10um, and to form a colored frame, such as three layers of white ink and one layer of black ink The combination of the white frame will lead to the film thickness of the decorative layer as high as 32-40um, and the decorative layer will form a high step difference at the junction of the touch area and the non-touch area. Timely generation of bubbles

Abstract

The present invention relates to a touch display apparatus. The touch display apparatus is defined to comprise a touch area for displaying an image and receiving a touch operation and a non-touch area surrounding the touch area. The touch display apparatus comprises a cover plate, a display panel, and a decorative layer and a shielding layer that are located between the cover plate and the display panel and are arranged corresponding to the non-touch area. The decorative layer is used for providing a required border color for the touch display apparatus, and the shielding layer is used for shielding electrical signal transmission cabling surrounding the touch display apparatus. The decorative layer is between the cover plate and the shielding layer. The shielding layer is made of metal or metal oxide. According to the touch display apparatus, metal or metal oxide is used as the shielding layer of the touch display apparatus, so that a probability of bubble generation in the touch display apparatus is reduced. In addition, light absorbance of a decorative border can be improved, thereby having a good shielding effect.

Description

technical field [0001] The invention relates to a touch display device. Background technique [0002] The touch display device includes an out-cell touch display device (OutCellTouchDisplay) and an in-cell touch display device (In-cellTouchDisplay), which define a touch area and a non-touch area surrounding the touch area. Usually, in the non-touch area, the surface of the touch display device is decorated by arranging multiple layers of light-shielding ink to cover the metal wiring for signal transmission and forming a colored decorative frame. Usually, the multi-layer ink is formed by a printing process, resulting in a high thickness of the ink layer, usually the thickness of each ink layer is about 8um to 10um, and to form a colored frame, such as three layers of white ink and one layer of black ink The combination of the white frame will lead to the film thickness of the decorative layer as high as 32-40um, and the decorative layer will form a high step difference at th...
