Folding display device

The present invention relates to a display device, and more particularly to a folding display device.

In recent years, flexible display technology has matured, and various manufacturers have begun to apply flexible displays to various products. In the case of a folding electronic product, when a user wants to use a folding electronic device, the folding electronic product can be unfolded to fully expand the flexible display screen and have a large display screen. When the user wants to carry, the folding electronic device can be folded to reduce the size of the folding electronic device to improve carrying convenience. That is to say, the foldable electronic device can simultaneously have the visual enjoyment of a large screen of a large-sized display device and the portability of a small-sized display device.

In general, foldable electronic products can reduce the size of the folded electronic products, but they will fold the flexible display of the folded electronic products, causing the internal circuit of the flexible display to be short-circuited or broken. risk. In addition, although an accommodating space is formed inside the folding electronic product, the flexible display screen can be flexibly accommodated in the accommodating space to avoid the occurrence of the folding, but the folding electronic product is opened when the electronic product is opened. The flexible display loses its support and cannot be leveled. Therefore, how to overcome the risk of short circuit and open circuit when the flexible display of the folding electronic product is folded in half and the problem of not easily flattening when opening is one of the problems that the researcher should solve.

The present invention relates to a folding display device, thereby simultaneously avoiding the risk of short circuit and open circuit when the flexible display of the folding electronic product is folded in half, and the problem of not easily flattening when opened.

The folding display device disclosed in the present invention comprises a pivoting member, a first housing, a first support plate, a second housing, a second support plate, a first coupling member, a second coupling member and a flexible display screen. The pivoting member has a first side and a second side opposite to each other. The first housing and the first support plate are respectively pivotally disposed on the first side of the pivoting member. The second housing and the second support plate are respectively pivotally disposed on the second side of the pivoting member. One end of the first coupling member is pivotally disposed on the first housing, and the other end of the first coupling member is pivotally disposed on the first support plate. One end of the second coupling member is pivotally disposed on the second housing, and the other end of the second coupling member is pivotally disposed on the second support plate. The flexible display screen includes a first bonding section, a flexing section and a second bonding section. The first joint segment and the second joint segment are respectively connected to opposite ends of the flexure segment. The first bonding section and the second bonding section are respectively attached to the first supporting board and the second supporting board. The first housing and the second housing are openable and closable relative to the pivoting member, and the first supporting member and the second supporting member are respectively engaged with the first pivoting member through the first coupling member, and the first supporting plate is opened and closed. The pivoting angle of the pivotal member with respect to the second supporting plate is greater than the pivoting angle of the first housing and the second housing relative to the pivoting member.

According to the folding display device disclosed in the above embodiment, the pivoting angle of the first supporting plate and the second supporting plate relative to the pivoting member is greater than that of the first housing and the second housing relative to the pivoting member through the four-bar linkage principle. The pivot angle. Thereby, when the folding display device is opened, the first support plate and the second support plate can support the flexible display screen in parallel with each other, and when the folding display device is received, the first support plate and the second support plate can The distance between the two support segments is increased by the relative inclination, so that the flexible display screen can be flexibly accommodated between the two support segments, thereby preventing the internal circuit of the flexible display screen from being pressed to cause a short circuit or an open circuit.
