The middle frame 11 may have the nature of not easy to be deformed, i.e., limited amount of deformation. The middle frame 11 has a first surface 111 and a second surface 112 opposite to each other. The display panel 12 refers to a display panel known or generally used by those skilled in the art, and is disposed on the first surface 111. The first fixed structure sets 20 are configured to fix the display panel 12 to the middle frame 11. Particularly, the first fixed structure set 20 is a technical means known to or generally used by those skilled in the art. For example, the first fixed structure set 20 may include a pillar disposed on the display panel 12 and having a screw hole and a hole disposed on the middle frame 11 and formed with a through-hole, and accordingly, a screw is fastened to the screw hole through the through-hole, so that the display panel 12 is fixed to the middle frame 11. In addition, in the above manner, it is preferable that the pillar may abut against a bottom surface of the hole.
The second fixed structure set 30 is configured to fix the display panel 12 to the middle frame 11, and a fixing configuration of the first fixed structure set 20 is different from a fixing configuration of the second fixed set structure 30.
Preferably, the number of the first fixed structure sets may be at least three. The at least three first fixed structure sets 20 and the at least one second fixed structure set 30 are disposed along four vertices of a rectangle. The display device 1 of the present invention uses a fixing scheme according to technical means known to or generally used by those skilled in the art in order to achieve the attachment between the display panel 12 and the middle frame 11 at the three fixed points where the first fixed structure sets 20 are positioned. In addition, the three fixed points may form a plane, so that it is possible to ensure that the display device 1 itself of the present invention is flattened and no residual internal stress is present. In addition, the second fixed structure set 30 having a predetermined structural arrangement is additionally used, and accordingly, the display panel 12 is locked to the middle frame 11 while a gap is maintained. Thus, under the condition that the display panel 12 is firmly fixed to the middle frame 11, the display panel 12 is prevented from being stressed at the fixed point of the second fixed structure set 30, so as to maximally ensure a state in which no internal stress exists in the display panel 12 itself. Accordingly, the display device 1 of the present invention can prevent the MURA effect from occurring in a liquid crystal display module (LCD module, LCM) of a screen display device due to deformation of the middle frame 11.
Referring to
As shown in the drawings, the second fixed structure set 30 will be further described. The second fixed structure set 30 includes a panel side fixing unit 31 and a middle frame side fixing module 32, in which the panel side fixing unit 31 is disposed on the display panel 12 to face the surface of the first surface 111, and the middle frame side fixing module 32 is disposed on the middle frame 11 to correspond to the panel side fixing unit 31.
The panel side fixing unit 31 includes a positioning member 311. The positioning member 311 may be formed of a metal material, and a first positioning section 312 is formed at one end of the positioning member 311 away from the display panel 12. Preferably, the positioning member 311 may be a vertical plate member vertically disposed from the display panel 12 toward the first surface 111.
The middle frame side fixing module 32 includes a mounting portion and a fixing member 323. The positioning member 311 and the fixing member 323 are respectively disposed on both sides of the mounting portion facing each other, and the fixing member 323 fixes the first positioning section 312. The mounting portion includes a cut-out opening 321, at least one fastening hole 322 and an inclined surface section 325. The cut-out opening 321 is formed to penetrate the first surface 111 and the second surface 112 to allow the positioning member 311 to pass through. In other words, the cut-out opening 321 may have a shape of a rectangular cut-out opening. The at least one fastening hole 322 is disposed on the second surface 112 and adjacent to the cut-out opening 321. In this embodiment, one fastening hole 322 is taken as an example, however, the present invention is not limited thereto. Particularly, a geometric center of the cut-out opening 321 and a geometric center of the fastening hole 322 may be preferably positioned on the same straight line. According to the drawings of the present embodiment, it appears as a straight line in the vertical direction, however, the configuration may be modified according to practical application. Therefore, the present invention is not limited thereto.
The fixing member 323 may be formed of a metal material, and have an approximately L-shaped structure. The fixing member 323 has a second positioning section 3231 and a circlelike hole 3232. In addition, the second positioning section 3231 is disposed on a short arm of the fixing member 323 having the L-shaped structure, and the circlelike hole 3232 is disposed on a long arm of the fixing member 323 having the L-shaped structure. The inclined surface section 325 is disposed on the second surface 112, in which the inclined surface section 325 gradually protrudes from the fastening hole 322 toward the cut-out opening 321 on the second surface 112, and a first end of the inclined surface section 325 protruding from the second surface 112 is parallel to a wall surface of the cut-out opening 321. In addition, the fastening hole 322 is formed in the inclined surface section 325 and the fastening hole 322 is adjacent to a second end of the inclined surface section 325, in which the second end is opposite to the first end.
When the fixing member 323 is disposed on the second surface 112, the second positioning section 3231 is fixed to the first positioning section 312. Preferably, the first positioning section 312 may be a through-hole such as a triangular hole, a rectangular hole or a circular hole. In this embodiment, a circular hole is exemplarily illustrated, however, the present invention is not limited thereto. In addition, the second positioning section 3231 may be a protruding pillar such as a triangular pillar, a rectangular pillar or a circular pillar. In this embodiment, a circular pillar is exemplarily illustrated, however, the present invention is not limited thereto. Thus, fixing the second positioning section 3231 to the first positioning section 312 corresponds to, for example, inserting the protruding pillar into the through-hole. The fastening member 324 using a screw known to or generally used by those skilled in the art is fastened to the fastening hole 322 through the circlelike hole 3232. Accordingly, the display panel 12 may be prevented from being stressed at the locking points of the second fixed structure set 30, so as to maximally ensure a state in which no internal stress exists in the display panel 12 itself.
Referring to
As shown in the drawings, preferably, the cut-out opening 321 has a width greater than a thickness of the positioning member 311, and the circlelike hole 3232 has an elongated elliptical shape. In other words, the elongated elliptical hole 3232 and the inclination of the inclined surface section 325 provide elasticity to adjust tension in which the display panel 12 is fixed to the middle frame 11 by using the second fixed structure set 30. When the fastening member 324 comes into close contact with one end of the second positioning section 3231 within the elongated elliptical hole 3232, pressure for contracting the display panel 12 inward may be provided, and when the fastening member 324 moves away from the end of the second positioning section 3231 within the elongated elliptical hole 3232, outward pressure may be applied to the display panel 12. The above manner can achieve the purpose of adjusting and relieving the internal stress of the display panel 12 and suppressing the occurrence of the MURA effect.
The fixed structure set according to the present invention is the same as or similar to the second fixed structure set of the display device of the present invention. In other words, details of the fixed structure set of the present invention have already been described in the display device of the present invention. Thus, identical or similar description will not be repeated herein.
The above description is only for illustrative purpose and is not restrictive. All modifications and changes within the scope without departing from the spirit of the present invention are included in the claims appended hereto.
