Abstract

The invention provides a curved touch display screen and a preparation method thereof. The curved touch display screen comprises a glass cover plate, wherein a touch film and a display screen are sequentially arranged at one side of the glass cover plate; the glass cover plate, the touch film and the display screen form a multi-layer composite structure, a first conducting circuit layer and a second conducting circuit layer are respectively arranged at two sides of the touch film, the first conducting circuit line is laminated to the glass cover plate, and the second conducting circuit layer is laminated to the display screen. According to the invention, OCA optical cement is adopted as an adhesive to be matched with the process of defoaming with a still kettle, so as to realize complete lamination of an OLED display screen which cannot resist high temperature with other components; then precise slab single-face heating and hot bending forming is performed, the process is simple, the rate of finished products and the stability of finished products are high, the production efficiency is greatly improved, the service life of the product is greatly prolonged, and the prepared curved touch screen has the performances of scratch resistance and full shielding and interference resistance, and has an arc field of view and arc angle of view, a convenient touch function and strong practicability.

Description

Technical field: [0001] The invention relates to the technical field of touch screen protective films, in particular to a curved touch display screen and a preparation method thereof. Background technique: [0002] With the development of technology, many display devices with curved surfaces appear, such as curved TVs. Compared with the flat touch screen, the curved touch screen can provide a wide panoramic image effect with its curved design surrounded by the direction of the user. Since any point on the screen is equal to the distance from the eyes, no matter whether the objects in the screen appear in the center or the edge, it will not happen. It also reduces the distortion of uneven viewing angle distance when viewed at a close distance, allowing the audience to fully immerse themselves in the wonderful and realistic pictures, bringing the audience a more realistic and comfortable look and feel. [0003] The current method of manufacturing a curved touch screen is to a...
