Problems solved by technology

Since the chip parts of the touch display device, such as the protective cover, the touch sensing element layer, and the display panel, will be processed by high-temperature processes (processes), the stress of each chip part will be released, resulting in various Warpage of sheet parts
When the gap between the parts above the sticker and the parts below shrinks with the thinning of the touch display device, it will also cause the upper and lower parts to contact each other, and then a Newton's ring phenomenon will occur, causing the traditional The display screen of the touch display device is defective

Embodiment Construction

[0045] refer to figure 1 , figure 1 A schematic cross-sectional view of a touch display device 200 according to an embodiment of the present invention is shown. The touch display device 200 includes a protective cover 101, such as tempered glass, which has a first surface 101A (outer surface) as a touch side, and a second surface 101B (inner surface) opposite to the first surface 101A. ). In this embodiment, the first surface 101A is a flat surface, while the second surface 101B has a curved concave surface, and the curved concave surface of the second surface 101B can be formed by grinding or etching. The concave shape may be a curved concave surface or an arched concave surface. In this embodiment, the shape of the concave surface is an arc-shaped concave surface, which is composed of a plurality of gradient slopes. The arched concave surface is composed of two side slopes and a middle plane.

Abstract

The embodiment of the invention provides a touch display device, a protective cover thereof and a lamination device. The touch display device comprises the protective cover, which is provided with a first surface and an opposite second surface, the first surface is an even surface, a touch-sensing element is arranged under the second surface of the protective cover, a display element is arranged under the touch-sensing element, border adhesive is arranged between the touch-sensing element and the display element, a clearance surrounded by the border adhesive is formed between the touch-sensing element and the display element, and the height of the center of the clearance is greater than the height of the circumference of the clearance. According to an embodiment, the protective cover of the touch display device comprises the even outer surface and the concave inner surface. The lamination device for the touch display device comprises a first tray and a second tray, which are respectively used for carrying the protective cover and the touch-sensing element. The invention can prevent the contact between the upper part and the lower part of the touch display device, thus overcoming the phenomenon of Newton's ring encountered by conventional touch display devices.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device using glue to join upper and lower parts. Background technique [0002] In the current touch display device, its main components such as the protective cover, the touch sensing element layer, and the display panel all belong to a sheet structure, and the touch sensing element layer attached to the protective cover can be used The glue is bonded with the display panel, and a gap surrounded by the glue is formed between the display panel and the touch sensing element layer. [0003] When the touch display device is gradually becoming thinner, the thickness of the sticker will be thinner, and the gap surrounded by the sticker between the display panel and the touch sensing element layer will also be reduced accordingly. Since the chip parts of the touch display device, such as the protective cover, the touch sensing element layer, and the display panel, will ...
