In order to describe the sliding structure, the second side plate 144 of FIGS. 1A and 2A has only a part, and the rest is omitted, but it is conceivable that the sliding structure 130 is slidably disposed in the sliding groove of the second side plate 144, and the appearance of the second side plate 144 The appearance is substantially the same as that of the first side plate 142. The first side plate 142 also has a sliding groove for sliding the rail (not shown), but it is not necessarily for the toothed track to slide, but for the general smooth track, mainly for the auxiliary and balancing track.

Next, referring to FIG. 1B and FIG. 2B, the display device 100 is engaged between the first toothed track T1 and the second toothed track T2 by the protruding teeth 130A of the wheel T3 to make the first display screen 110 and the second display. The screens 120 are overlapped with each other by the rotation of the reel T3 or each of them is expanded in a opposite direction into a wide display screen of a larger size, providing different user needs for use. In FIG. 1B, when the second display screen 120 is overlaid on the first display screen 110, one end of the first toothed track T1 and one end of the second toothed track T2 overlap each other, and the wheel T3 is positioned. Between the two ends, and the position of the reel T3 is substantially at a central position of the back plate 140 and the two display screens 110, 120 which are superposed on each other. In addition, in FIG. 2B, when the first display screen 110 and the second display screen 120 are respectively deployed, the other end of the first toothed track T1 and the other end of the second toothed track T2 overlap each other, and the wheel T3 It is positioned between the other ends, and the position of the wheel T3 is substantially at the center of the back plate 140 and the unfolded two display screens 110, 120. Therefore, regardless of how the two display screens 110, 120 are moved, the convex teeth 130A of the reel T3 can maintain the meshing state with the bi-toothed rails T1, T2, and stably between the ends of the bi-toothed rails T1, T2. mobile.

In detail, the reel T3 has a rim 130B surrounding the side surfaces of the convex teeth 130A, and its circumferential surface is slightly higher than the ridge lines of the convex teeth 130A, and functions as a limit ring to support the two-toothed track T1. The card limit of T2 is located on one side of the rim 130B. In addition, a tooth groove 130C is formed between adjacent convex teeth 130A, for example, a sector-shaped tooth groove. When the convex teeth 130A rollly contact the first tooth-shaped track T1 and the second tooth-shaped track T2, the first tooth-shaped track T1 and the second tooth-shaped track T2 can be engaged in the groove 130C to hold the wheel T3. Move back and forth on a straight path, not easy to fall off.

Next, FIG. 3 is another schematic diagram of the second display screen after deployment. Referring to FIG. 2A and FIG. 3, after the second display screen 120 is deployed, although the display area of the first display screen 110 and the display area of the second display screen 120 can be combined into a larger display area, the second display screen 110, 120 If they are at different levels, they do not actually reach a seamless joint. In order to enable the two adjacent sides S3, S4 of the two display screens 110, 120 to be truly joined together, the display device 100 is designed to be tilted by an angle of an axis, for example, 10 degrees to 15 degrees. Left and right, so that the first display screen 110 and the second display screen 120 are slightly V-shaped (one tilt, the other does not need to be tilted), so that there is no obvious gap between the adjacent two sides S3, S4 of the different horizontal planes. presence.

In the embodiment of FIG. 3, the back surface of the second display screen 120 is provided with, for example, two torsion springs 150 respectively located at opposite ends of the axial direction E for providing a force when the second display screen 120 is rotated. Please refer to FIG. 4A and FIG. 4B , which are a side view and a top view of the torsion spring disposed in the axial direction of FIG. 3 . In FIG. 4A, the torsion spring 150 generates a torsion force between the two application points G1 and G2. When the two display screens 110 and 120 are overlapped, the torsion force abuts between the two display screens 110 and 120, respectively. The external interference force is in a state of static balance, and the second display screen 120 cannot be rotated. However, when the external display force is less than the torsion force after the two display screens 110, 120 are deployed, the torque will force the second display screen 120 to rotate until its back side obliquely contacts the backing plate 140. Therefore, the adjacent two sides S3, S4 of the two display screens 110, 120 can be truly joined together.

In the embodiment, when the second display screen 120 is tilted, the second toothed track T2 is engaged with the sliding slot of the second side plate 144, and thus does not rotate with the second display screen 120. At the same time, the torsion spring 150 applies a force on the first stud F1 of the second toothed track T2 to generate a reaction force, so that the second display screen 120 is thereby reacted (ie, torque) relative to the second toothed track. T2 rotates to keep it tilted. Moreover, the second protruding column F2 is further provided with a second protrusion F2, and the side of the second display screen 120 is provided with a groove F3. When the second display screen 120 is not inclined, the second protruding column F2 Can be accommodated in the groove F3. When the second display screen 120 rotates, the groove F3 moves downward and is not at the same level as the second protrusion F2, thereby releasing the engagement state, but when the second display screen 120 is applied to return to the horizontal state At this time, the second stud F2 returns to the engaged state with the groove F3. The above-mentioned snapping manner is only one of the possible positioning mechanisms, and the invention is not limited.

In the present embodiment, although only one sliding structure 130 is described, it includes two-toothed rails T1, T2 and a reel T3. However, it is conceivable that the display device 100 can have a set of sliding structures on the opposite side of the first display panel 142 and the second side panel 144 of the two display screens 110, 120, and the operation is the same, and is omitted here. Moreover, the supporting force provided by the backboard 140 can be replaced by other supporting mechanisms. Even without the support of the backboard 140, the two display screens 110, 120 can still be superposed or unfolded by the sliding structure 130, so The embodiment of the present display device 100 is not affected.

In summary, the display device of the present invention includes a first display screen, a second display screen, and a sliding structure. The first display screen has a first toothed track and the second display screen has a second toothed track. The second display screen is slidably overlapped or unfolded on the first display screen, and the second display screen is expanded to form a wide display screen with the first display screen. The surface of the runner has a plurality of convex teeth, and the convex teeth rollly contact the first toothed track and the second toothed track, and are in the first toothed track with the relative movement of the first and second display screens The ends of the two-toothed rail move between. Therefore, the display device is applied to a notebook computer, and the size of the screen can be changed from a single screen size to a double screen size, and the width is extended to be twice as wide as the original, so that the user can use a larger screen; When you go out, you can also stack the two display screens to reduce the space occupied and make the storage more flexible.
