The invention relates to a display technology, in particular to a display, which has a structural design for preventing a metal layer material from scratching a panel.
Organic light-emitting diode (OLED) folding screens are the hottest technology in the display industry today. In order to meet the user's good experience and the aesthetics of the product itself, it pursues thinning in the research of both screen in-folding and out-folding. For products that need to be folded out, a back of the panel needs a metal layer material to support and reduce waviness. In order to achieve the purpose of thinning, although an existing back plate made of a material such as polyimide (PI) or polyethylene (PE) has a supporting effect, it is difficult to reduce the occurrence of wrinkles, so the use of the back plates has been excluded. While only a thin stainless steel (SUS) material is used as the metal layer for the back of the panel, since the metal layer is thinner and sharp, it easily scratches the panel during pad bending.
In order to solve the problem of the conventional light-emitting diode (OLED) folding screen that the metal layer is easy to scratch the panel during pad bending, there is an urgent need to develop a novel display having a structural design for preventing a metal layer material from scratching a panel.
In view of this, the present invention provides a display. By blunting an edge of a metal sheet to provide a blunt structure which can prevent the sharp metal sheet from scratching a panel during pad bending, thereby improving a yield of pad bending in a module manufacturing process.
Therefore, according to an embodiment of the present invention, the present invention provides a display, including: a panel including a bending area and two non-bending areas disposed on opposite sides of the bending area; and a first metal sheet and a second metal sheet respectively disposed on the two non-bending areas, wherein an end portion of at least one of the first metal sheet and the second metal sheet close to the bending area has a blunt structure.
In an embodiment of the present invention, a side of the first metal sheet close to the bending area is provided with a support plate integrally formed with the first metal sheet, so that the side of the first metal sheet close to the bending area has an increased thickness to form the blunt structure.
In an embodiment of the present invention, the second metal sheet is provided with an adhesive material integrally formed with the second metal sheet, and the adhesive material covers an upper side and a lower side of the second metal sheet.
In an embodiment of the present invention, each of end portions of the first metal sheet and the second metal sheet close to the bending area has the blunt structure.
In an embodiment of the present invention, the blunt structure is adjacent to an upper surface of the panel.
In an embodiment of the present invention, an upper side and a lower side of each of end portions of the first metal sheet and the second metal sheet close to the bending area have the blunt structure.
In an embodiment of the present invention, the blunt structure is a chamfered structure.
In an embodiment of the present invention, the panel is an organic light emitting diode panel, and the display further includes a touch panel, a polarizer, and a coating, which are sequentially arranged on the panel corresponding the first metal sheet from top to bottom.
In an embodiment of the present invention, the display further includes a circuit trace electrically connected to the second metal sheet.
In an embodiment of the present invention, when the display is bent, the second metal sheet is located above the first metal sheet.
