DETAILED DESCRIPTION OF THE INVENTION

FIG. 1A is a schematic three-dimensional view of a display panel according to the first embodiment of the present invention, and FIG. 1B is a schematic sectional view taken along a section of a line I-I in FIG. 1A. Referring to FIG. 1A and FIG. 1B, a display panel 100 of this embodiment includes a frame 110, a panel body 120, and a plurality of elastic buffer members 130. The frame 110 and the panel body 120 are assembled, and the frame 110 surrounds the panel body 120 and the elastic buffer members 130, as shown in FIG. 1A.

The material of the frame 110 may be plastic, and the frame 110 includes a frame plate 112 and a frame body 114. The frame plate 112 has a plane 112a and an opening 112b. The opening 112b is located in the plane 112a, and the frame body 114 is disposed on the plane 112a and surrounds the opening 112b. Specifically, the frame body 114 includes four frame bars 114a, in which the frame bars 114a are connected with each other and surrounding the opening 112b. Each frame bar 114a has two end portions E1 and a center portion C1. In each frame bar 114a, the center portion C1 is located between the end portions E1, and end portions E1 of two adjacent frame bars 114a are connected with each other, thereby forming the frame body 114.

The panel body 120 is disposed on the plane 112a and covers the opening 112b. The panel body 120 is located among the elastic buffer members 130. The panel body 120 may be applied to an existing liquid crystal display panel, that is, the panel body 120 may be an existing liquid crystal panel body. In other words, the panel body 120 may include a thin film transistor (TFT) array substrate (not shown), a color filter substrate (not shown), and a liquid crystal layer (not shown).

The material of the elastic buffer members 130 may be plastic, and the elastic buffer members 130 may be integrally formed with the frame 110. For example, the elastic buffer members 130 and the frame 110 may be manufactured by the same injection molding process. Moreover, the elastic buffer members 130 are disposed on the plane 112a and face each other, and each elastic buffer member 130 is located between one of the frame bars 114a and the panel body 120.

Each elastic buffer member 130 includes a stop block 132 and a support plate 134, as shown in FIG. 1B. The support plate 134 is connected between the stop block 132 and the frame plate 112 and has a contact plane 134a. A thickness T1 of the support plate 134 is between 1 mm and 2 mm. The stop block 132 protrudes from the contact plane 134a. After the frame 110 and the panel body 120 are assembled, the contact plane 134a faces the panel body 120, so when the display panel 100 shakes due to transportation, or when a vibration test is performed, the panel body 120 will collide with the contact plane 134a.

When the panel body 120 collides with the contact plane 134a, the support plate 134 is bent under the collision of the panel body 120, and meanwhile an elastic force is applied to the panel body 120, so as to stop the panel body 120 continuing to move toward the support plate 134. In this way, the support plate 134 may alleviate the collision force of the panel body 120 with the support plate 134, thereby avoiding a crack or a fracture occurring in the panel body 120 due to the collision with the frame 110.

Additionally, each stop block 132 may have a slope 132a and a bottom 132b. The bottom 132b is connected between the slope 132a and the contact plane 134a, and an included angle A1 between the bottom 132b and the slope 132a is smaller than 90 degrees. For example, the included angle A1 as shown in FIG. 1B is smaller than 45 degrees. When a worker mounts the panel body 120 into the frame 110 from the top down, the slopes 132a enable the panel body 120 to smoothly pass through the stop blocks 132, and the elastic buffer members 130 can clip the panel body 120, so as to fix the panel body 120 between the bottoms 132b of the stop blocks 132 and the plane 112a.

The number of the elastic buffer members 130 may be equal to or more than eight. Taking FIG. 1A as an example, the number of the elastic buffer members 130 included by the display panel 100 is ten. Eight elastic buffer members 130 are corresponding to the end portions E1 respectively, and the remaining two elastic buffer members 130 are corresponding to the two center portions C1 respectively. Therefore, in this embodiment, each elastic buffer member 130 is closely adjacent to one end (that is, the end portion E1) or a center part (the center portion C1) of one of the frame bars 114a.

Although FIG. 1A shows ten elastic buffer members 130, according to the size of the panel body 120 and the type of a display to which the display panel 100 is applied, the display panel 100 may include only two elastic buffer members 130. For example, when the display panel 100 includes a small-size panel body 120 and is manufactured into a screen of a handheld electronic device such as a mobile phone or a personal digital assistant (PDA), the display panel 100 may include only two elastic buffer members 130 corresponding to the center portions C1, and the two elastic buffer members 130 may still have the function of clipping and fixing the panel body 120.

Moreover, in other embodiments, the number of the elastic buffer members 130 may be just eight, and the eight elastic buffer members 130 are corresponding to the end portions E1 respectively. That is to say, the two elastic buffer members 130 corresponding to the center portions C1 may be omitted. It can be known that the number and the distribution of the elastic buffer member 130 as shown in FIG. 1A are merely illustrated as an example, and are not intended to limit the present invention.

FIG. 2A is a schematic three-dimensional view of a display panel according to the second embodiment of the present invention, and FIG. 2B is a schematic partial enlarged view of one of the elastic buffer members in FIG. 2A, in which FIG. 2B is a schematic enlarged view of a region R1 in FIG. 2A. Referring to FIG. 2A and FIG. 2B, a display panel 200 of this embodiment is similar to the display panel 100, for example, the display panel 200 also includes a frame 110 and a panel body 120, and differences between the display panels 200 and 100 are mainly introduced hereinafter.

The display panel 200 further includes a plurality of elastic buffer members 230. The elastic buffer members 230 are disposed on a plane 112a face to face, and the frame 110 surrounds the panel body 120 and the elastic buffer members 230. The elastic buffer members 230 are different from the elastic buffer members 130 in structure. Specifically, each elastic buffer member 230 includes a bump 232 and a blade spring 234. The bump 232 is disposed on the plane 112a and may be connected with the frame body 114, and the blade spring 234 is disposed between the bump 232 and the panel body 120 and is connected with the bump 232.

In each elastic buffer member 230, a gap G1 exists between the blade spring 234 and the bump 232, as shown in FIG. 2B. The material of the elastic buffer members 230 may be plastic, and the elastic buffer members 230 may be integrally formed with the frame 110. For example, the elastic buffer members 230 and the frame 110 may be manufactured by the same injection molding process or be formed of the same object through the same machining process. Each blade spring 234 has an outward convex camber 234a facing the panel body 120, so when the display panel 200 shakes due to transportation, or when a vibration test is performed, the panel body 120 will collide with the outward convex camber 234a.

Since the gap G1 exists between the blade spring 234 and the bump 232, when the panel body 120 collides with the outward convex camber 234a, the blade spring 234 may be deformed and thus is depressed toward the gap G1, and meanwhile the blade spring 234 applies an elastic force to the panel body 120, so as to stop the panel body 120 continuing to move toward the blade spring 234. In this way, the blade spring 234 may alleviate the collision force of the panel body 120, so as to avoid a crack or a fracture occurring in the panel body 120 due to the collision with the frame 110.

It can be noted that FIG. 2A shows ten elastic buffer members 230 in which eight elastic buffer members 230 are corresponding to end portions E1 of all frame bars 114a respectively, and the remaining two elastic buffer members 230 are corresponding to center portions C1 of two of the frame bars 114a respectively, but the display panel 200 may include only two elastic buffer members 230 corresponding to the center portions C1 according to the size of the panel body 120 and the type of a display to which the display panel 200 is applied.

Moreover, in other embodiments, the number of the elastic buffer members 230 may be just eight, and the eight elastic buffer members 230 are corresponding to the end portions E1 respectively, that is, the two elastic buffer members 230 corresponding to the center portions C1 may be omitted. Therefore, the number and the distribution of the elastic buffer member 230 as shown in FIG. 2A are merely illustrated as an example, and are not intended to limit the present invention.

FIG. 3A is a schematic three-dimensional view of a display panel according to the third embodiment of the present invention, and FIG. 3B is a schematic partial enlarged view of one of the elastic buffer members in FIG. 3A, in which FIG. 3B is a schematic enlarged view of a region R2 in FIG. 3A. Referring to FIG. 3A and FIG. 3B, a display panel 300 of this embodiment is similar to the display panel 100. For example, the display panel 300 also includes a frame 110 and a panel body 120, and differences between the display panels 300 and 100 are mainly introduced hereinafter.

Specifically, the display panel 300 further includes a plurality of elastic buffer members 330. The elastic buffer members 330 are disposed on a plane 112a face to face, and the frame 110 surrounds the panel body 120 and the elastic buffer members 330. The elastic buffer members 330 are different from the elastic buffer members 130 in structure.

In detail, each elastic buffer member 330 includes a stop plate 332 and a plurality of elastic members 334. In each elastic buffer member 330, the stop plate 332 is located between the elastic members 334 and the panel body 120, and the elastic members 334 are connected with the stop plate 332 and the frame body 114. The elastic members 334 may be springs, and each stop plate 332 has a contact plane 332a. The contact planes 332a face the panel body 120.

When the display panel 300 shakes due to transportation, or when a vibration test is performed, the panel body 120 will collide with the contact plane 332a, so that the stop plate 332 presses the elastic members 334. At this time, the pressed elastic member 334 is compressed to generate an elastic force. This elastic force is applied to the stop plate 332 and able to stop the panel body 120 continuing to move toward the stop plate 332. In this way, the elastic buffer member 330 may alleviate the collision force of the panel body 120, so as to avoid a crack or a fracture occurring in the panel body 120 due to the collision with the frame 110.

It can be noted that in the embodiment as shown in FIG. 3A, the number of the elastic members 334 included by each elastic buffer member 330 is two, but in other embodiments, the number of the elastic members 334 included by each elastic buffer member 330 may be only one or more than two (such as three). Therefore, the number of the elastic members 334 as shown in FIG. 3A and FIG. 3B is merely illustrated as an example, and is not intended to limit the present invention.

Additionally, it can be noted that although FIG. 3A shows ten elastic buffer members 330 in which eight elastic buffer members 330 are corresponding to end portions E1 of all frame bars 114a respectively, and the remaining two elastic buffer members 330 are corresponding to center portions C1 of two of the frame bars 114a respectively, the display panel 300 may also include only two elastic buffer members 330 according to the size of the panel body 120 and the type of a display to which the display panel 300 is applied.

Moreover, in other embodiments, the number of the elastic buffer members 330 may be just eight, and the eight elastic buffer members 330 are corresponding to the end portions E1 respectively, that is, the two elastic buffer members 330 corresponding to the center portions C1 may be omitted. Therefore, the number and the distribution of the elastic buffer member 330 as shown in FIG. 3A are merely illustrated as an example, and are not intended to limit the present invention.

In view of the above, when the display panel shakes due to transportation, or when a vibration test is performed, a plurality of elastic buffer members included by the display panel of the present invention may apply an elastic force to a moving panel body, so as to stop the panel body continuing to move toward the frame. In this way, the present invention can alleviate the collision force of the panel body, thereby avoiding a crack or a fracture occurring in the panel body.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
