Vehicle-mounted capacitive touch display and manufacturing process thereof

Abstract

The invention relates to a vehicle-mounted capacitive touch display and a manufacturing process thereof. The display comprises a transparent glass cover plate, a touch screen function sheet and a display module; the glass cover plate is provided with a non-visible region and a visible region in a closed ring shape; the non-visible region is located in a peripheral edge region of the glass cover plate; the visible region is located in the non-visible region; the upper surface of the glass cover plate is covered by a black semi-transparent explosion-proof film; a region corresponding to the non-visible region of the lower surface of the glass cover plate is provided with a shielding layer; the touch screen function sheet is arranged on the display module; the glass cover plate covers the touch screen function sheet; and the touch screen function sheet is located below the visible region of the glass cover plate. By arranging the black semi-transparent explosion-film film on the glass cover plate, the non-visible region of the glass cover plate achieves an integrated black effect together with the color of the touch screen function sheet; and by testing, the process difficulty of arranging a semi-transparent layer on the lower surface of the glass cover plate is avoided, so that the production cost is reduced, the production efficiency is improved, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a capacitive touch display for a vehicle and a manufacturing process thereof. Background technique [0002] Capacitive touchscreens are increasingly finding their way into cars as consumers have grown accustomed to using smartphones and tablets in their daily lives. The content displayed on the car screen comes from a wide range of sources, both inside and outside the car. Moreover, many newer applications now require touchscreen panels, which change the role of automotive displays from simply presenting visual information to actual human-machine interfaces. This shift is driving display design requirements toward easy-to-view designs that incorporate larger sizes, non-rectangular or curved shapes, and higher resolutions, as the amount of data displayed increases. A general capacitive touch display is provided with an opaque layer around it and there is a significant co...

Problems solved by technology

The main defect of this method is that the uniformity of the thickness of the semi-permeable layer is not well controlled, resulting in uneven brightness and darkness in the visible area, and the impurities and white spots in the semi-permeable layer cause a very high defect rate and difficult inspection. The lower the yield rate, and this method can only be printed one by one, the efficiency is low, the production cost is high, the process is complicated, and there are environmental problems, and it is not suitable for large-scale production
