Abstract
The invention discloses a touch structure and a flexible display with the touch structure. The touch structure comprises a first insulating layer; a first metal layer is arranged on the first insulating layer, and a plurality of first touch electrodes distributed in a grid mode and first metal wires connected between the first touch electrodes are arranged in the first metal layer; the second metal layer is arranged above the first metal layer, and a plurality of second touch electrodes distributed in a grid mode and second metal wires connected between the second touch electrodes are arrangedin the second metal layer; wherein the first metal wires and the second metal wires form an intersection region; the second insulating layer is arranged between the first metal wires and the second metal wires; at least one flexible insulator is arranged in the second insulating layer, and the flexible insulator is located in the intersection area. The flexible display provided by the invention is easier to fold and better in structure, effectively prevents touch failure under repeated bending and high-strength impact, and improves the quality and use performance of the flexible display.
Description
technical field [0001] The present invention relates to the fields of displays and the like, in particular to a touch control structure and a flexible display with the touch control structure. Background technique [0002] With the rapid development of display technology, active matrix organic light-emitting diode (AMOLED) flexible display technology has attracted great attention, including large-size full-screen, bendable, even foldable, fixed-curve mobile phones in the future. The market will be widely used. [0003] However, the poor mechanical reliability of flexible panels with bendable or foldable features is the main obstacle to the mass production of such products. The existing touch structure usually uses metal mesh (Metalmesh) technology to combine silver, copper Metal materials such as glass or polyethylene terephthalate (PET) are placed on plastic films such as glass or polyethylene terephthalate (PET), and are grown to form conductive metal grid patterns. The ...
